For example, the at least one sensor 540 may include a grip sensor. The electronic device 100 may identify whether the electronic device 100 is gripped by using the grip sensor. For example, the at least one sensor 540 may include an acceleration sensor (eg, a 6-axis sensor). The electronic device 100 may detect an arrangement state of the electronic device 100 using the acceleration sensor, and may detect whether the electronic device 100 is placed on an object according to the arrangement state.

Hereinafter, an example of the mobile device 530 will be described.

According to various embodiments, the moving device 530 may include devices for slidingly moving the display 510 (or the first structure 101 or the first plate 111a). For example, the moving device 530 may include a motor for rotating the above-described roller 151 in one direction (eg, clockwise or counterclockwise). In addition to the motor, the moving device 530 may include various devices for rotating the roller 151 to slide the display 510 (or the first structure 101 or the first plate 111a). have. Meanwhile, without being limited thereto, the electronic device may include a guide member and/or a guide structure (eg, a fixing member) for guiding the display 103 instead of the roller 151 .

Meanwhile, according to various embodiments, the present invention is not limited thereto, and as described above, the display 510 is manually performed by a user (eg, the display 510 (or the first structure 101 , or the first plate 111a). ) may be slid in a first direction (eg, direction ①) or pull in a second direction opposite to the first direction). In this case, the mobile device 530 may be implemented in the electronic device 100 , but the embodiment is not limited thereto and the mobile device 530 may not be implemented as shown in FIG. 5 .

Hereinafter, an example of the processor 560 will be described. At least some of the modules (eg, the movement control module 561, the movement detection module 563, and the refresh rate control module 565) included in the processor 560 of the electronic device 100 are software, firmware, hardware, Or it may be implemented (eg, implemented) as a combination of at least two or more of them. For example, the modules may include an application executable by the processor 560 of the electronic device 100, a program, computer code, instructions, a routine, Or it may be stored in the electronic device 100 in the form of a process. When the modules are executed by the processor 560 , the modules may cause the processor 560 to perform an operation associated with the module.

First, the movement control module 561 will be described.

According to various embodiments, the movement control module 561 may control the display 510 (or the first structure 101 or the first plate 111a) of the electronic device 100 to slide. For example, the movement control module 561 may drive the above-described movement device 530 (eg, a motor) to control the roller 151 to rotate in one direction to slide the display 510 . . For example, when the movement control module 561 rotates the roller 151 in a first direction (eg, counterclockwise), the display 510 slides out and moves, and the roller 151 ) in the second direction (eg, clockwise), the display 510 slides in and rotates in the second direction after rotating the roller 151 in the first direction. In this case, the display 510 may slide-out and then slide-in. According to the control of the movement control module 561 , a distance at which the display 510 slides (eg, a slide-out movement or a slide-in movement) may be limited (eg, about 40 mm). For example, the maximum distance the slide-out moves is the maximum distance exposed to the outside through the second structure 102 in the state in which the first structure 101 is accommodated in the second structure 102 . As such, it may be determined by at least one of a width of the first structure 101 or a width of the second structure 102 . Also, for example, the maximum distance the slide-in moves is when the first structure 101 is the second structure in a state in which the first structure 101 is maximally exposed to the outside through the second structure 102 . The distance received into ( 102 ), which may also be determined by at least one of the width of the first structure ( 101 ) or the width of the second structure ( 102 ). For example, as at least one of the width of the first structure 101 and the width of the second structure 102 increases, the slide movement of the first structure 101 (eg, a slide out movement or a slide in movement) When the first structure 101 is guided (or supported) by the inner lower surface of the second structure 102, it can be slid for a longer distance.

According to various embodiments, the movement control module 561 may control the display 510 to slide based on occurrence of a specified event. For example, the specified event identifies the execution and/or operation of the specified app, and a user input (eg, identification of selection of an icon, pressing of a physical key) for triggering a slide movement of the flexible display. identification) may be included.

According to various embodiments, the display 510 (or the first structure 101, or the first plate 111a) slides at a predetermined speed (eg, a slide out movement, a slide movement) can be controlled. For example, the movement control module 561 moves so that the display 510 is moved at a speed (eg, 40 mm/sec) that moves to a maximum distance (eg, about 40 mm) for a preset time (eg, 1 sec). The device 530 (eg, a motor) may be controlled. The speed is not limited to the description, and may be set, reset, and/or changed to various values. Also, for example, the movement control module 561 may control the display 510 to slide and move at a speed determined based on various information (eg, external illumination). For example, the movement control module 561 may control the display 510 to move at a lower speed as the external illuminance decreases.

Meanwhile, the present invention is not limited thereto, and as described above, the display 510 may be pulled and moved by the user as described above. Even in this case, the control operation of the electronic device 100 described in this document may be applied mutatis mutandis. For example, while the display 510 of the electronic device 100 is pulled by the user, hovering values of a designated area of the display 510 are recognized, and movement of the display 510 is performed based on the recognized hovering values. A limiting operation (eg, limiting the movement of the first structure 101 so that the display is no longer pulled) may be performed.

Hereinafter, the movement detection module 563 will be described.

According to various embodiments, the movement detection module 563 is configured to perform the display 510 (or the first structure 101, or the first plate 111a) based on the value obtained from the at least one sensor 540 described above. ) of the slide movement state (eg, whether the slide movement is started or whether the slide movement is completed), and the distance to which the slide is moved may be detected. Also, the movement detection module 563 may identify a parameter associated with an area of the display 510 that is changed according to the slide movement of the display 510 . In an embodiment, the parameter determines the area (or the length in one direction (eg, the direction in which the display is drawn in and out (eg, the horizontal direction, the X direction)) of the area exposed to the outside of the display 510 ). may include For example, the movement detection module 563 may identify a distance to which the display 510 is slid, and calculate an area corresponding to the identified distance to which the display 510 is slid. The movement detection module 563 may identify the area of the area of the display 510 currently exposed to the outside by adding the calculated area to the area before the display 510 is slid. Also, in an embodiment, the parameter may include a ratio (eg, a screen expansion ratio) of an exposed area to an accommodated area of the display 510 . For example, the movement detection module 563 identifies the distance to which the display 510 is slid, and compares the identified slidable distance with the maximum slidable distance of the display 510 to generate the display 510 . It is possible to identify the ratio of the exposed area to the accommodated area of . Also, in an embodiment, the parameter may include a distance at which the current display 510 is drawn (or a retracted distance). For example, the movement detection module 563 may identify the distance at which the display 510 is drawn by identifying the distance through which the display 510 is slid. The refresh rate control module 565 may determine a refresh rate to be set in the area of the display 510 based on the parameter associated with the identified area of the display 510 , which will be described later.

Hereinafter, the refresh rate control module 565 will be described.

According to various embodiments, the refresh rate control module 565 may set the refresh rate of at least a partial area of the display. The operation of setting the refresh rate of the region may mean that the refresh rate control module 565 controls the display driver IC 520 to set the refresh rate of at least a partial region of the display 510 . The refresh rate is defined as the number of frames of content displayed on the display 510 for a specified period of time (eg, 1 sec), and the display driver IC 520 controls the display in all directions (eg, horizontal direction) to implement one frame. It can be set by controlling the time at which pixels (or elements) are turned on once. For example, the refresh rate control module 565 may transmit information 601 for setting the refresh rate to the display driver IC 520 . For example, as shown in FIG. 6 , the information 601 for setting the scan rate may include information on a specific region in which the scan rate is to be controlled (eg, information on gate lines corresponding to a specific region) or in a specific region. It may include at least one of information about the scan rate to be set. The display driver IC 520 may control the gate driver IC 523 to display content in a specific area at a specific refresh rate based on the received information, which will be described later. In an embodiment, the refresh rate control module 565 identifies information (eg, coordinate information) on the location of a specific region (eg, a region currently exposed to the outside, or a sub-region divided when using a multi-window), and identifies It is possible to identify information on a gate line disposed at a position corresponding to the information on the changed position. In another embodiment, the scan rate control module 565 identifies information on the externally exposed region based on the movement detection module 563, and based on the parameter identified by the movement detection module 563 described above Information on a refresh rate to be set in an area exposed to the outside of the display 510 may be identified. For example, the scan rate control module 565 may set the scan rate in proportion to the value of the parameter. For example, the refresh rate control module 565 may identify a higher refresh rate as the area of the exposed region, the screen expansion ratio, and/or the slide movement distance increases. In another embodiment, the refresh rate control module 565 may identify information on the above-described divided regions of the display 510 and identify information on a refresh rate to be set in the identified divided regions. For example, the refresh rate control module 565 identifies information on sub-regions of the display 510 generated based on the occurrence of an event for using the multi-window as described above, and identifies the area ( Alternatively, information on a refresh rate to be set for each area may be identified based on a length (eg, width or length) in one direction (eg, a direction in which the display is moved).

Hereinafter, the display driver IC 520 will be described. Although described later, the display driver IC 520 may include a plurality of display driver ICs 520 or a single display driver IC 520 . Meanwhile, the display driver IC 520 is not limited to the configurations shown in FIG. 5 and may include more configurations. For example, the display driver IC 520 may further include a power module, a control register, and a graphic RAM (GRAM). Since the display driver IC 520 may be implemented as a known technology, a detailed description of the display driver IC 520 other than the display driver IC 520 described below will be omitted.

According to various embodiments, the display driver IC 520 may display content on at least a partial area of the display 510 at a specified refresh rate. For example, the display driver IC 520 receives information about the content to be displayed from the processor 560, and as shown in FIG. 6, a region (eg, external) from the processor 560 (eg, a refresh rate control module). It is possible to receive information about an area exposed to the , or one of the divided areas) and information about a scan rate to be set in the area. The display driver IC 520 Vsync at a period corresponding to the scan rate along with information on the gate line to be controlled by the gate driver IC 523 based on the received information on the region and the information on the scan rate to be set in the region. A signal (vertical synchronization signal) and a Hysnc signal (horizontal synchronization signal) may be provided (or transmitted, or transmitted). For example, when the Vsync signal is provided with a first period (eg, 1/60 Hz) corresponding to the scan rate, the Hsync signal may be provided with a period smaller than the first period (eg, 1/60 Hz). The Vsync signal indicates the start and/or end of one frame when displaying content (eg, indicates the end of a previous frame or the beginning of a new frame when receiving a Vsync signal), and the Hsync signal includes a plurality of gates for displaying one frame. A time point at which a pulse is applied may be indicated for each line. The gate driver IC 523 identifies gate lines corresponding to the information on the line, and sequentially applies a pulse to each of the plurality of gate lines based on the received Vsync signal and Hsync signal for each of the identified gate lines. You can do horizontal line updates. According to the application of the pulse, the light sources or transistors connected to each gate line are turned on, and in the turned-on state, the light sources or transistors respond to the voltage applied to the source line (or data line). It can be controlled so that light of a corresponding intensity is output by the The display driver IC 520 may transmit pixel data (eg, RGB data) to be displayed for each pixel of the area to the source driver IC 525 using the timing controller 521 based on the content information. The source driver IC 525 is configured to correspond to pixel data of light sources (eg, OLED) or transistors (eg, TFT) included in each of the plurality of pixels of the region of the display 510 based on the pixel data. By applying a voltage, a portion of content (eg, one pixel of content) corresponding to pixel data may be displayed for each pixel. Meanwhile, after the above-described vertical synchronization signal (Vsync signal) is provided, display update may be performed for a relatively short period of time rather than using the entire period until the next vertical synchronization signal, but various embodiments are not limited thereto. Those skilled in the art will understand. For example, the display driver IC 520 may be configured to provide a vertical synchronization signal and to provide a horizontal synchronization signal (Hsync signal) without a rest period at a constant period until the next vertical synchronization signal is provided.

According to various embodiments, the display driver IC 520 stores information 603 for a plurality of refresh rates in advance (eg, in the memory 527 ) as shown in FIG. 6 , and stores the stored information and the processor ( 560), the scan rate of the specific region may be controlled based on information about the scan rate to be set in the specific region. For example, as shown in FIG. 6 , the information 603 on the plurality of refresh rates may include a plurality of preset refresh rate values and information on the types of applications corresponding to the plurality of preset refresh rate values. . The display driver IC 520 identifies a refresh rate corresponding to the refresh rate or application type information received from the processor 560 among a plurality of refresh rate values, and identifies a refresh rate to be set in a specific area based on the identified refresh rates. This can be done, which will be described later with reference to FIGS. 11 to 15 . Meanwhile, without being limited thereto, the information on the plurality of refresh rates may be stored in a separate memory (eg, the memory 2130 of FIG. 21 ) in the electronic device 100 instead of the display driver IC 520 . have. In addition, without being limited to the above description, the processor 560, not the display driver IC 520, identifies information on the refresh rate to be set in the region, and finally, based on the information about the plurality of scan rates stored in advance, the region It is also possible to identify a scan rate to be set in .

In an embodiment, the electronic device 100 may include a plurality of display driver ICs (eg, a first display driver IC 711 and a second display driver IC 712 ) as shown in 701 of FIG. 7 . can For example, the plurality of display driver ICs (eg, the first display driver IC 711 and the second display driver IC 712 ) may be configured in a plurality of regions (eg, the first region 511 ) of the display 510 . . ) can be controlled. The number of display driver ICs (eg, the first display driver IC 711 and the second display driver IC 712 ) includes a plurality of regions (eg, the first region 511 ) for independently controlling the refresh rate; It may correspond to the number of second regions 513). In another embodiment, the electronic device 100 controls the plurality of regions (eg, the first region 511 and the second region 513 ) of the display 510 as shown in 702 of FIG. 7 . It may include a single display driver IC 721 for Hereinafter, when a plurality of display driver ICs are implemented (eg, 701 in FIG. 7 ) and when implemented as a single display (eg, 702 in FIG. 7 ), respective implementation examples and operation examples will be described in detail.

First, examples in which a plurality of display driver ICs (eg, the first display driver IC 711 and the second display driver IC 712 ) are implemented and operation examples will be described with reference to FIGS. 8A and 8B .

According to various embodiments, as shown in FIG. 8A , the electronic device 100 includes a plurality of pre-designated (or preset) areas (eg, a first area 511 , a first area A plurality of display driver ICs (eg, a first display driver IC 711 and a second display driver IC 712 ) for controlling the second region 513 ) may be included. In this case, as shown in FIG. 8A , the scan rates of the regions (the first region 511 and the second region 513 ) divided in a direction (eg, the Y direction) perpendicular to the draw-in and pull-out directions of the display are independently determined. It can be controllable (or configurable). A plurality of predefined regions (eg, first region 511, second region) controlled by the plurality of display driver ICs (eg, first display driver IC 711 and second display driver IC 712 ) The area of the region 513) may be fixed. For example, the electronic device 100 includes a first display driver IC 711 for controlling a first area exposed to the outside and a second display driver IC 713 for controlling a retractable or retractable second area. may include Also, for example, when the multi-window is used, the predetermined layout includes a plurality of sub-areas (or a plurality of spaces), and accordingly, when the multi-window is used, a plurality of areas ( Example: The first area 511 and the second area 513) may be preset. Meanwhile, the display 510 is not limited thereto, and more regions may be set on the display 510 (eg, the number of divided regions when using a multi-window is preset to three or more). One display driver IC (eg, the first display driver IC 711 or the second display driver IC 713 ) among the plurality of display driver ICs may include a region (eg, the first region 511 ) of the display 510 . Alternatively, in order to control the plurality of pixels 800 of the second region 513), the device may be electrically connected to a device (eg, a light source or a transistor) for each pixel corresponding to (or disposed in one region) of the region. have. For example, one gate driver IC (eg, the first gate driver IC 813 or the second gate driver IC 823 ) is connected to the gate lines of one region, and one source driver IC (eg, the first source) The driver IC 815 or the second source driver IC 825 may be connected to source lines of one region. For example, a gate driver IC (eg, first gate driver IC 813 or second gate driver IC) of one display driver IC (eg, first display driver IC 711 or second display driver IC 713 ) 823 ) is a region (eg, a first region 511 or a second region) of the plurality of gate lines 801 extending in a direction (eg, Y direction) perpendicular to the direction in which the display 510 is drawn in or pulled out. A device connected to (eg, connected to a gate input terminal) disposed in the second region 513) and disposed for each pixel of one region (eg, the first region 511 or the second region 513). , a pulse voltage transmitted in the vertical direction (eg, Y direction) may be applied. In addition, the source driver IC (eg, the first source driver IC 815 or the second source driver IC 825 of one display driver IC (eg, the first display driver IC 711 or the second display driver IC 713 )) )) is a region (or region) of a plurality of data lines 802 (or source lines) extending in a direction (eg, an X direction or a horizontal direction) corresponding to a direction in which the display 510 is drawn in or drawn out. For example, connected to data lines (eg, connected to a source input terminal) disposed in the first region 511 or the second region 513), and pixels in one region (eg, the first region or the second region) As an element arranged for each element, it is possible to provide pixel data for content display in the horizontal direction (eg, the X direction). The processor 560 (eg, the refresh rate control module 565) is configured to use at least some of the plurality of display driver ICs (eg, the first display driver IC 711 and the second display driver IC 713) for setting the refresh rate. Information (eg, information 601 for setting the refresh rate of FIG. 6 ) may be transmitted. For example, as described above with reference to FIGS. 6 to 7 , the processor 560 (eg, the refresh rate control module 565 ) is configured in one region (eg, the first region 511 or the second region 513 ). Identifies information for setting the refresh rate, and transmits information for setting the refresh rate of one area to the one area among a plurality of display driver ICs (eg, the first display driver IC 711 or the second display driver IC 713 ) It can be passed to a display driver IC associated with (eg, set to control an area). As an example, when the processor 560 (eg, the refresh rate control module 565 ) sets the scan rate in a specific region larger than one region (eg, the first region 511 or the second region 513 ), the specific region Information for setting the refresh rate of a part included in one area (eg, the first area 511) among the areas is transmitted to the first display driver IC 711, and another area (eg, the second area) of the specific area (eg, the second area ( 513)), information for setting the refresh rate of other parts may be transmitted to the second display driver IC 713 . For example, the specific area may be an area exposed to the outside of the display 510 . As another example, the processor 560 (eg, the refresh rate control module 565 ) identifies a plurality of scan rates to be set for each of a plurality of preset regions (eg, the first region 511 and the second region 513 ). can For example, the processor 560 (eg, the refresh rate control module 565 ) may identify a plurality of sub-scan rates to be set for each of the plurality of sub-regions when the multi-window is used. The processor 560 (eg, the refresh rate control module 565 ) displays information for setting the scan rate of one region (eg, the first region 511 ) based on the identification of a plurality of sub-scan rates, to the first display. It is transmitted to the driver IC 711 , and information for setting a refresh rate of another region (eg, the second region 513 ) may be transferred to the second display driver IC 713 . Each of the plurality of display driver ICs (eg, the first display driver IC 711 and the second display driver IC 713 ) includes received regions (eg, the first region 511 , the second region 513 ). A Vsync signal and an Hsync signal may be generated based on the information for setting the scan rate for each region, and the scan rate may be controlled for each region based on the generated signals (eg, a Vsync signal and an Hsync signal). For example, the first display driver IC 711 (eg, the first timing controller 811 ) is provided in the first period T1 corresponding to the received refresh rate information (or corresponding to the first scan rate). The first Vsync signal (Vsync_#1) and the first Hsync signal (Hsync_#1) in the 1-1 period (T1-1) smaller than the first period (T1) are transferred to the first gate driver IC 813, It is possible to control content to be displayed at a first refresh rate in one area (eg, the first area 511 ). Similarly, the second display driver IC 713 (eg, the second timing controller 821 ) is provided in the second period T2 corresponding to the received scan rate information (or corresponding to the second scan rate). The second Vsync signal (Vsync_#2) and the second Hsync signal (Hsync_#2) of the second period (T2-2) shorter than the second period (T2) are transferred to the second gate driver IC (823). , it is possible to control content to be displayed at the second refresh rate in another area (eg, the second area 513 ). Since the operation of displaying content by the display driver IC 520 is the same as described above, a redundant description will be omitted. When the first scan rate is lower than the second scan rate, the first period T1 of the first Vsync signal Vsync_#1 is the second period of the second Vsync signal Vsync_#2 as shown in FIG. 8A . It can be longer than (T2). Conversely, when the first scan rate is higher than the second scan rate, the first period T1 of the first Vsync signal Vsync_#1 is the second period T2 of the second Vsync signal Vsync_#2. could be shorter. In addition, when the first scan rate and the second scan rate are the same, the first period T1 of the first Vsync signal Vsync_#1 is the same as the second period T2 of the second Vsync signal Vsync_#2. can

In this case, the operations of the first gate driver IC 813 and the second gate driver IC 823 are performed as described above, and a single source driver IC may provide pixel data to pixels of the entire area.

Also, the present invention is not limited to that shown in FIG. 8A, and as shown in FIG. 8B , the plurality of gate lines 801 are arranged (or extended) in a direction horizontal to the direction in which the display is drawn in or drawn out (eg, the X direction). and the plurality of source lines 802 may be disposed (or extended) in a vertical direction (eg, a Y direction). In this case, as shown in FIG. 8B , the scan rates of the regions (the first region 511 and the second region 513 ) divided in a direction (eg, the X direction) horizontal to the input and output directions of the display are independently determined.

For example, the processor 560 (eg, the refresh rate control module 565 ) may identify a specific region and a scan rate to be set in the specific region. The processor 560 (eg, the refresh rate control module 565) identifies one display driver IC (eg, the first display driver IC 711 of the plurality of display driver ICs) based on the identification of the refresh rate to be set in the specific region. ) or the second display driver IC 713 ) for setting the refresh rate of a specific region (eg, information on the specific region and information on the refresh rate to be set in the specific region) may be transmitted.

The single display driver IC 721 may be electrically connected to a plurality of pixels 800 included in the entire area of the display 510 as is known in the art. Since the arrangement of the gate lines 801 and the arrangement of the source lines 802 are the same as those described above with reference to FIG. 8A , overlapping descriptions will be omitted. A single display driver IC 721 is configured to set a refresh rate for each of a plurality of regions (eg, the first region 511 and the second region 513 ) from the processor 560 (eg, the refresh rate control module 565 ). Information (eg, information 601 for setting the scan rate of FIG. 6 ) may be received, and the scan rate may be controlled for each area based on the received information. For example, based on the received information (eg, the information 601 for setting the refresh rate of FIG. 6 ), the single display driver IC 721 sends the third gate driver IC 833 to a region (eg: Information on first gate lines corresponding to the first region 511) and the first Vsync in a first period T1 corresponding to a first scan rate to be set in one region (eg, the first region 511) The first Hsync signal Hsync_#1 is transmitted in the 1-1 period T1-1 shorter than the signal Vsync_#1 and the first period T1, and in another region (eg, the second region 513) ) and the second Vsync signal (Vsync_#2) in the second period T2 corresponding to the second scan rate to be set in one region (eg, the second region 513) and the second Hsync signal Hsync_#2 may be transmitted in a 2-2 second period T2-2 shorter than the second period T2. The magnitude relationship between the periods (eg, the first period T1, the 1-1 period T1-1, the second period T2, and the 2-1 period T2-1) is as described above. Since they are the same, overlapping descriptions are omitted. At this time, the third gate driver IC 833 receives the received signals (eg, first to second Vsync signals (Vsync_#1, Vsync_#2), first to second Hsync (Hsync_#1, Hsync_#2) )), when turning on (eg, turning on a light source or transistor) pixels in one region (first region 511) and another region (second region 513), one region ( The time at which the pixel is turned on in the first region 511) and the time at which the pixel is turned on in another region (the second region 513) do not overlap may be controlled. A single display driver IC 721 (eg, the third timing controller 831 ) uses the third source driver IC 835 to form a plurality of regions (eg, the first region 511 , the second region ( 513)) When the pixels included in each are turned on, pixel data is transmitted to the turned-on pixels, and content is displayed for each of a plurality of regions (eg, the first region 511 and the second region 513). can do.

According to various embodiments, as shown in FIG. 8E , the electronic device 100 includes a source input terminal of a device (eg, a light source or a transistor) disposed in the plurality of pixels 800 of the entire area of the display 510 . It may include a single display driver IC 721 independently electrically connected to the . As described above, the single display driver IC 721 is the third gate driver IC 833, which includes information on the first gate lines corresponding to one region (eg, the first region 511) and one region ( Example: The first period T1 corresponding to the first scan rate to be set in the first region 511), and the 1-1 period T1 shorter than the first Vsync signal Vsync_#1 and the first period T1 -1) to transmit the first Hsync, information on second gate lines corresponding to another region (eg, the second region 513) and to be set in one region (eg, the second region 513) The second Hsync may be transmitted in a second Vsync signal Vsync_#2 in a second period T2 corresponding to the second scan rate and in a second period T2-2 shorter than the second period T2. However, in the third gate driver IC 833 , the time when the pixel is turned on in one region (the first region 511 ) does not overlap with the time when the pixel is turned on in another region (the second region 513 ). A single display driver IC 721 is included for each of a plurality of regions (eg, the first region 511 and the second region 513 ) using the third source driver IC 835 without the need to control the By transferring pixel data to each pixel, content can be displayed for each of a plurality of regions (eg, the first region 511 and the second region 513 ).

In addition, according to various embodiments, more operations than those illustrated in FIG. 9 or at least one fewer operations may be performed. Hereinafter, FIG. 9 will be described with reference to FIGS. 10A to 10B.

According to various embodiments, the electronic device 100 may identify the first parameter associated with the first area of the display 510 in operation 901 . For example, the electronic device 100 (eg, the movement detection module 563 ) may identify a parameter associated with the currently exposed area of the display 510 . As described above, the parameters are the area of the externally exposed area (eg, the first area A1), the exposed area (eg, the first area A1) and the other accommodated area (eg, the second area). (A2)) ratio (eg, a screen expansion ratio) or a distance at which the display 510 is drawn out (or a retracted distance) may be included. For example, as shown in 1001 of FIG. 10A , the electronic device 100 may display an exposed area (eg, a first area (first area A1 in FIGS. 1 to 3 ) in a state in which the display 510 is retracted to the maximum as shown in 1001 of FIG. 10A . ))) and associated parameters can be identified. As another example, as shown in 1004 of FIG. 10B , the electronic device 100 includes an exposed area (eg, the first area A1 and the second area A2) in a state in which the display 510 is drawn out to the maximum, as shown in 1004 of FIG. 10B . Associated parameters can be identified. Without being limited thereto, the electronic device 100 is in a state in which the display 510 is retracted or withdrawn by a predetermined distance rather than the maximum according to the reciprocating movement of the first structure (eg, 1002 and 1003 in FIG. 10A , and FIG. 10B ). At 1005 and 1006 , parameters associated with an exposed area of the display 510 (eg, at least a portion of the first area A1 and the second area A2 ) may be identified.

According to various embodiments, the electronic device 100 uses the at least one display driver IC 520 in operation 903 to display the content at the first refresh rate associated with the first parameter. You can control the area. For example, the electronic device 100 (eg, the refresh rate control module 565 of the processor 560 ) controls the currently exposed area (eg, the first area A1 ) based on the identified value of the first parameter. Information for setting the refresh rate may be identified, and information for setting the refresh rate of the identified currently exposed area (eg, the first area A1) may be transmitted to the display driver IC 520 . As described above in FIG. 6 , the information for setting the scan rate (eg, the information 601 for setting the scan rate of FIG. 6 ) includes information about an exposed area (eg, the first area A1 ) (eg, exposure). information on gate lines corresponding to the exposed region) or information on a scan rate to be set in the exposed region. A scan rate (eg, a first scan rate) to be set in the first area A1 may be set in proportion to a value of a parameter associated with the exposed first area A1 . The display driver IC 520 may transmit the Vsync signal and the Hsync signal to the gate driver IC 523 at a cycle corresponding to the first scan rate based on the received scan rate setting information as described above. The gate driver IC 523 sequentially applies a pulse to each of the gate lines corresponding to the first area A1 based on the Vsync signal and the Hsync signal to turn the plurality of pixels in the first area A1. - It can be controlled to be on. All of the plurality of pixels in the first area A1 may be continuously turned on at a cycle corresponding to the first scan rate. The source driver IC 525 transmits the pixel data to the turned-on pixels according to the application of the pulse, thereby providing the first content with the first scan rate on the first area A1 as shown in 1001 of FIG. 10A . (1011) can be displayed. Alternatively, the description is not limited thereto, and as illustrated in 1004 of FIG. 10B , the third content 1041 may be displayed on the first area A1 and the second area A2 at the third scan rate. As described above, the first content 1011 may include an execution screen of an application and various types of media content such as images and images. The display driver IC 520 can be implemented with a plurality of display driver ICs 711 and 713 or a single display driver IC 721 as described above with reference to FIGS. 8A to 8E, and the operation is as described above. Therefore, redundant descriptions are omitted. Hereinafter, examples of an operation of identifying a scan rate to be set in a currently exposed area (eg, the first area A1 ) based on the identified parameter of the electronic device 100 will be described.

In an embodiment, the electronic device 100 may calculate a scan rate to be set in the exposed region based on a preset maximum scan rate and a ratio of the current parameter to the maximum parameter as shown in Equation 1 below. For example, the maximum refresh rate may be a preset refresh rate corresponding to a state in which the display 510 is maximally exposed. The electronic device stores information on the maximum scan rate in advance, and when the currently identified first parameter (eg, the area of the currently exposed area (eg, the first area A1 )) is maximally exposed to the stored maximum scan rate. The scan rate to be set for the currently exposed area (e.g., the first area A1) is obtained by multiplying the ratio of the parameter of can be calculated

Also, without being limited to what is described, using the formula substituted with the minimum parameter instead of the maximum parameter and with the minimum scanning rate preset to correspond to the case of being drawn in at the maximum instead of the maximum scanning rate of [Equation 1], the exposed area ( Example: A scan rate to be set in the first area A1) may be calculated.

In another embodiment, the electronic device 100 stores in advance information on a plurality of refresh rate values corresponding to each of the plurality of parameter values, and a first corresponding to the currently identified first parameter among the plurality of refresh rate values. 1 It is also possible to identify the refresh rate.

According to various embodiments, the electronic device 100 determines that at least a portion of the second area A2 is exposed according to the movement of the first structure in operation 905 , based on the identification of the first area A1 and the second area ( A second parameter associated with at least a portion of A2) may be identified. For example, the electronic device 100 may cause the display 510 to display based on the occurrence of an event set to cause the slide movement of the display 510 (or the first structure 101 or the first plate 111a). It can be controlled to slide. The specified event identifies the execution and/or operation of the specified app, and a user input for triggering a slide movement of the display 510 (eg, identification of an icon selection, identification of pressing a physical key) may include doing Based on the identification of the occurrence of the specified event, the electronic device 100 may control the moving device 530 (eg, a motor) to rotate the roller 151 to move the first structure. As the first structure moves, at least a portion of the area (eg, the second area A2 ) accommodated in the electronic device 100 as shown in 1001 , 1002 , and 1003 of FIG. 10A is moved to the outside. can be exposed According to the slide movement of the display 510 , the electronic device 100 identifies at least a portion of the first area A1 and the second area A2 exposed to the outside of the display 510 , and moves to the identified outside. A second parameter associated with at least a portion of the exposed first area A1 and the second area A2 (eg, an area of at least a portion of the first area A1 and the second area A2 exposed to the outside, exposure A ratio (eg, a screen expansion ratio) of at least a portion of the first and second areas A1 and A2 and another portion of the accommodated second area A2, or a distance at which the display 510 is drawn out (or , at least one of the incoming distance) can be identified. In this case, the value of the second parameter may be greater than the value of the previously identified first parameter. Also, without being limited thereto, according to the movement of the first structure, as shown in 1004 , 1005 , and 1006 of FIG. 10B , some of the areas exposed to the outside of the display 510 into the inside of the electronic device 100 ( Example: A portion of the second area A2) may be introduced. In this case, the electronic device 100 determines parameters related to other non-introduced portions of the first and second areas A1 and A2 exposed to the outside (eg, an area of an externally exposed region, an externally exposed region). At least one of a ratio (eg, a screen reduction ratio) or a distance to which the display 510 is drawn (or a distance from which the display 510 is drawn) may be identified. In this case, the value of the identified second parameter may be smaller than the value of the previously identified first parameter. Since the operation of identifying the parameter associated with the exposed region of the electronic device 100 is the same as described above, a redundant description will be omitted.

According to various embodiments, the electronic device 100 identifies a new parameter (eg, a second parameter) based on satisfaction of a specified condition so that content is displayed at a new refresh rate (eg, second scan rate, third scan rate). The display driver IC 520 may be controlled. For example, the satisfaction of the specified condition may include that a specified time elapses (eg, n seconds have elapsed) after the display 510 is drawn in or pulled out.

According to various embodiments, the electronic device 100 displays the content at the second refresh rate identified based on the second parameter in operation 907 in the first area A1 and the second area of the display 510 . At least a part of (A2) can be controlled. For example, the electronic device 100 (eg, the refresh rate control module 565 of the processor 560 ) controls the currently exposed area (eg, at least a portion of the first area A1 and the second area A2 ). Information for setting the refresh rate may be identified, and information for setting the refresh rate of the identified currently exposed region may be transmitted to the display driver IC 520 . As an example, the electronic device 100 is a scan rate to be set in at least a portion of the first area A1 and the second area A2 , and a second scan rate corresponding to the value of the second parameter (eg, FIG. 10A ). of the third refresh rate) can be identified. Based on the value of the second parameter being higher than the value of the first parameter, the second scan rate (eg, or the third scan rate of FIG. 10A ) may be set to be higher than the previously identified first scan rate. The second display driver IC 520 is configured to correspond to the refresh rate to be set in at least a portion of the exposed first area A1 and the second area A2 based on the received refresh rate setting information as described above. The second Vsync signal Vsync_#2 and the second Hsync signal Hsync_#2 having the second period may be transmitted to the gate driver IC 523 . The gate driver IC 523 operates the first and second regions A1 and A2 based on the signals (eg, the second Vsync signal Vsync_#2 and the second Hsync signal Hsync_#2). By sequentially applying a pulse to each of the gate lines corresponding to at least a portion, at least a plurality of pixels in the first area A1 and the second area A2 may be controlled to be turned on. The source driver IC 525 transmits the pixel data to the turned-on pixels according to the application of the pulse, so that the second scan rate (eg, the third scan rate of FIG. 10A ) is performed on the first area A1 . The second content 1021 (eg, or the third content 1031) may be displayed. Also, for example, without being limited to the description, as shown in FIG. 10B , when the display 510 is slid in, the displayed contents 1051 and 1061 have a lower refresh rate than the previous refresh rate (eg, the third refresh rate) ( Example: 2nd scan rate, 1st scan rate).

According to various embodiments, the electronic device 100 may control the display driver IC 520 to display content by gradually changing from the previously identified first refresh rate to the second refresh rate. For example, the electronic device 100 (eg, the refresh rate control module 565 of the processor 560 or the display driver IC 520 ) may identify a plurality of intermediate scan rates between the first scan rate and the second scan rate. . The electronic device 100 (eg, the refresh rate control module 565 or the display driver IC 520 of the processor 560) transmits Vsync signals and Hsync signals having a plurality of periods corresponding to the plurality of intermediate refresh rates. sequentially transferred to the gate driver IC 523 so that the scan rate of the exposed region (eg, at least a portion of the first region A1 and the second region A2) is changed from the first scan rate to the second scan rate can be controlled

As illustrated in 1202 of FIG. 12 , the electronic device 100 may identify a scan rate (eg, a first scan rate 1221 ) corresponding to the identified parameter. Operations 1101 to 1103 of the electronic device 100 may be performed in the same manner as operations 901 to 905 of the electronic device 100 , and thus overlapping descriptions will be omitted. Meanwhile, not limited to the description and/or illustrated, even when the display 510 is retracted, the operation of identifying the parameter may be performed as described above.

As shown in 1202 of FIG. 12 , the electronic device 100 responds to the parameter associated with the previously stored exposed area (eg, at least a portion of the first area A1 and the second area A2) of the display 510 . Based on the identified scan rate (eg, the first scan rate 1221) and a plurality of pre-stored scan rate values (eg, first to fourth set scan rates), the exposed area (eg, the first scan rate) is compared based on the comparison result.

Information for setting the identified second scan rate (e.g., the second set scan rate) (e.g., information on gate lines corresponding to at least a part of the first area A1 and the second area A2 and the second scan rate information) may be transmitted to the display driver IC 520 .

For example, as shown in 1703 of FIG. 17A , the electronic device 100 performs two applications (eg, a first application (App 1) and a second application (App 2)) executed in the foreground mode. The exposed area of the display 510 may be divided in a vertical direction to be divided into two sub areas (a first sub area 1731 and a second sub area 1732 ). Also, for example, when at least three or more applications are executed as a plurality of icons are selected as shown in 1706 of FIG. 17B , the electronic device 100 divides the entire area of the display 510 into three or more sub-areas ( For example, it may be divided into a third sub-region 1761 , a fourth sub-region 1762 , and a fifth sub-region 1763 ). Three or more sub-regions (eg, the third sub-region 1761, the fourth sub-region 1762, and the fifth sub-region 1763) are implemented with different sizes, and in the arrangement example shown in 1706 of FIG. 17B It is not limited and may be arranged in various examples. Also, for example, as shown in 1707 of FIG. 17B , the electronic device 100 divides the exposed area of the display 510 in the horizontal direction, and divides the exposed area into sub areas (eg, the sixth sub area 1771 and the second sub area 1771 ). 7 sub-regions 1772) may be created. Implementation examples of the above-described sub-regions may be combined. Meanwhile, the event for using the multi-window may include various events in addition to receiving an input for executing an application on the multi-window panel.

For example, as shown in 1703 of FIG. 17A , the electronic device 100 may slide the display 510 so that the display 510 is maximally drawn out based on the occurrence of an event for using the multi-window. can Meanwhile, without being limited to the description and/or illustrated, the electronic device 100 has an area corresponding to (eg, proportional to) the number of the plurality of sub-regions (or the number of executed applications) of the area of the display 510 . The display 510 may be slidably moved by a distance corresponding to the area to be exposed to the outside. Alternatively, the display 510 may be pulled out by the user after the occurrence of an event for using the multi-screen without being limited thereto.

According to various embodiments, in operation 1605 , the electronic device 100 may identify the first refresh rate based on a parameter related to the exposed area of the display 510 . For example, the electronic device 100 may identify a parameter associated with the currently exposed area of the display 510 and identify a scan rate (eg, a first scan rate) corresponding to the identified parameter. The operation of identifying the parameter of the electronic device 100 and the scan rate corresponding to the parameter may be performed as described above in operations 901 to 907 of the electronic device 100, and thus a redundant description will be omitted.

According to various embodiments, the electronic device 100 performs at least a scan rate independently controllable (or configurable) among the plurality of sub-regions based on lengths in one direction of the plurality of sub-regions divided in operation 1607 . Some sub-regions may be identified. For example, the electronic device 100 measures the entire length of the display 510 in one direction (eg, vertical direction, Y direction) and the length of the plurality of sub-regions in one direction (eg, vertical direction, Y direction). Based on the comparison, at least some sub-regions whose scan rate is independently controllable among the plurality of sub-regions may be identified. For example, the one direction may be a direction perpendicular to a direction in which the display is drawn in or drawn out, a direction in which gate lines are arranged, or a direction in which a pulse is applied by the display driver IC 520 (eg, the gate driver IC 523 ). . In an embodiment, as described above with reference to FIG. 8A , the one direction may be a vertical direction (or a Y direction). In another embodiment, as described above with reference to FIG. 8B , the one direction may be a horizontal direction (or an X direction). For convenience of description, hereinafter, the gate line extends in a vertical direction, and the one direction is described as a vertical direction (or Y direction) as an example. For example, the electronic device 100 selects some sub-regions having a length in the vertical direction (hereinafter, referred to as a control length) corresponding to the total length L of the display 510 in the vertical direction among the plurality of sub-regions. It may be identified, and it may be identified that the scan rate is independently controllable for some identified sub-regions. As an example, referring to 1703 of FIG. 17A , the electronic device 100 has a control length L in a vertical direction among a plurality of sub-regions (eg, the first sub-region 1731 and the second sub-region 1732 ). The first sub-region 1731 and the second sub-region 1732 having . As another example, referring to 1707 of FIG. 17B , the electronic device 100 includes a plurality of sub-regions (eg, a sixth sub-region) having a length (eg, SL3, SL4) shorter than the control length L in the vertical direction. 1771 and the seventh sub-region 1772) can be independently identified as regions in which the scan rate cannot be controlled. In this case, as shown in 1707 of FIG. 17B , the electronic device 100 includes a plurality of sub-regions (eg, the sixth sub-region 1771 and the seventh sub-region 1771 ) at the first scan rate identified to be set in the exposed region. The scan rate of the region 1772) may be set. Also, for example, the electronic device 100 may identify some sub-regions having the control length L in the vertical direction by summing among the plurality of sub-regions as independently controllable regions. In this case, the electronic device 100 identifies sub-regions that are adjacent to each other (eg, in contact with each other) and disposed in one direction (eg, a vertical direction) among the sub-regions, and the length of the identified sub-regions in one direction When corresponding to the control length by summing , the identified sub-regions may be identified as independently controllable regions. As an example, referring to 1706 of FIG. 17B , the electronic device 100 moves in a vertical direction among a plurality of sub-regions (the third sub-region 1761 , the fourth sub-region 1762 , and the fifth sub-region 1763 ). In addition to the third sub-region 1761 having a control length L, the fourth sub-region 1762 and the fifth sub-region 1762 and 5 1763 may be identified as regions 1760 in which the scan rate is independently controllable.

Meanwhile, the present invention is not limited thereto, and when the display driver IC is implemented as described above with reference to FIGS. 8D and 8E , scan rates of all sub-regions may be independently controllable.

According to various embodiments, in operation 1609 , the electronic device 100 performs at least one sub-scan rate corresponding to the at least partial sub-region based on the size and the first scan rate of at least some sub-regions identified as independently controllable. may be identified, and the display driver IC 520 may be controlled to display content at the at least one sub refresh rate identified in operation 1611 . For example, the electronic device 100 controls sub-regions (eg, the first sub-region of FIG. 17A ) identified as having a controllable scan rate independent of the scan rate (eg, the first scan rate) identified as being set in the exposed region. Based on the length (or area) of 1731 and the second sub-region 1732 and 1700 of FIG. 17B in another direction (eg, a horizontal direction), a scan rate (eg, the second sub-region) to be set in the identified regions 1 sub-scan rate, second sub-scan rate) may be determined. The electronic device 100 (eg, the scan rate control module 565 of the processor 560 ) provides information for setting a scan rate for each sub-region (eg, information on gate lines corresponding to each sub-region, and the sub-region) information on the refresh rate to be set for each of the fields) may be transmitted to the display driver IC 520 . The display driver IC 520 generates a Vsync signal and an Hsync signal having a period corresponding to the information on the gate line for each sub-region and the refresh rate for each sub-region, and controls the content to be displayed (eg, the gate driver IC 523 ). ) control, source driver IC 525 control). Since the control operation of the display driver IC 520 has been described above, a redundant description thereof will be omitted. Hereinafter, an example of an operation of identifying a scan rate to be set in sub-regions of the electronic device 100 will be described.

According to various embodiments, the electronic device 100 is configured based on the longest length (hereinafter, the maximum horizontal length) among the lengths of the sub-regions controllable independently of the first scan rate in another direction (eg, the horizontal direction). , a scan rate to be set in all of the plurality of sub-regions (or an exposed area of the display 510 (eg, at least a portion of the first area A1 and the second area A2)) may be identified. For example, the electronic device 100 reflects the ratio of the maximum horizontal length to the total length in the horizontal direction of the display 510 to the first scan rate as shown in [Equation 2] below, so that the plurality of sub-regions A scan rate to be set in the entire area (or in an exposed area of the display 510 (eg, at least a portion of the first area A1 and the second area A2 )) may be calculated. As an example, referring to 1703 of FIG. 17A , the electronic device 100 displays a first horizontal length ( sw1-1) is identified as being the longest, the ratio of the first horizontal length sw1-1 to the total horizontal length W1 of the display is calculated, and the calculated ratio may be multiplied by the first scan rate.

Without being limited thereto, when the gate line extends horizontally and the pulse application direction of the gate driver IC 523 is horizontal, the equation substituted for “vertical” instead of “horizontal” in [Equation 2] is the scan rate. can be used to identify.

According to various embodiments of the present disclosure, the electronic device 100 controls each of the independently controllable sub-regions based on the first scan rate and the length of each of the independently controllable sub-regions in a different direction (eg, a horizontal direction). It is possible to identify the scan rate to be set in . For example, in the electronic device 100, the length of one sub-region in the horizontal direction and the total length of the display 510 in the horizontal direction at the first scan rate as shown in [Equation 3] below. A scan rate to be set in each of the plurality of sub-regions may be calculated by reflecting the length ratio. As an example, referring to 1703 of FIG. 17A , the electronic device 100 calculates a ratio of each of the horizontal lengths (eg, sw1-1, sw1-2) of the plurality of sub-regions to the total horizontal length w of the display. Thus, the calculated ratio may be multiplied by the first scan rate.

Without being limited thereto, when the gate line extends horizontally and the pulse application direction of the gate driver IC 523 is horizontal, the equation substituted for “vertical” instead of “horizontal” in Equation 3 above is the scan rate. can be used to identify.

According to various embodiments, as described above, referring to FIG. 17C , the electronic device 100 stores a plurality of refresh rate values and/or information on a content type corresponding to the plurality of refresh rate values 1511 based on It is also possible to determine the scan rate to be set for each sub-region. For example, the electronic device 100 may identify information on content to be displayed for each sub-region (eg, information on the type of application) and identify a scan rate corresponding to the identified type of application. For example, as shown in FIG. 17C , the electronic device may identify the second set refresh rate 1782 corresponding to the type (eg, App B) of the application App 2 displayed on the second sub area 1732 . have. The electronic device 100 determines a scan rate 1781 (eg, a first set scan rate) identified based on the scan rate (second sub scan rate) identified as being set in the sub-region and a scan rate corresponding to the identified type of application ( 1782) (eg, a second set scan rate), and based on the comparison result, a scan rate to be finally set in the sub-region may be identified (eg, a higher first set scan rate is identified). Since the operation of identifying the scan rate based on the comparison result of the electronic device 100 has been described above with reference to FIGS. 11 to 15 , a redundant description will be omitted.

According to various embodiments, when the sub-region is changed while the multi-window is being used, the electronic device 100 may change the scan rate set in the changed sub-region. For example, when the areas of the sub-regions (eg, the first sub-region 1731 and the second sub-region 1732 ) are changed, the electronic device 100 may change the lengths of the sub-regions in the horizontal direction based on the A scan rate set for each sub-region may be changed. For example, as shown in 1801 of FIG. 18 , the electronic device 100 includes a plurality of sub-regions between the plurality of sub-regions (eg, the first sub-region 1731 and the second sub-region 1732 ). An object 1811 (eg, a line) for adjusting the size is displayed, and a plurality of sub-regions (eg, the first sub-region 1731 and the second sub-region 1731 ) are displayed based on a user input to select and drag the object 1811 The area of the 2 sub-regions 1732) may be adjusted. Based on the ratio (or difference) between the length of the sub-region in the horizontal direction before the area change of the sub-region and the changed length of the sub-region in the horizontal direction, the electronic device 100 performs a scan rate (eg, the first sub-scan rate or second sub-scan rate) can be changed. For example, the electronic device 100 reflects the ratio of the length in the horizontal direction before the change of the sub-region to the changed length in the horizontal direction of the sub-region in the scan rate before the change of the sub-region as shown in Equation 4 below. Thus, the changed scan rate (eg, the third sub scan rate or the fourth sub scan rate) may be calculated. The electronic device 100 may control the display driver IC 520 to display content in a plurality of sub-regions (eg, the first sub-region 1731 and the second sub-region 1732 ) at the changed refresh rate. .

Without being limited thereto, when the gate line extends horizontally and the pulse application direction of the gate driver IC 523 is horizontal, the formula substituted for “vertical” instead of “horizontal” in Equation 4 above is the scan rate can be used to identify

In an embodiment, as illustrated in 1802 of FIG. 18 , the electronic device 100 includes a plurality of sub-regions (eg, a first sub-region 1731 and a second sub-region 1732 ) arranged side by side in a vertical direction. ) can be controlled to be arranged in the horizontal direction. The electronic device 100 independently controls the scan rate among the plurality of sub-regions based on a change in the arrangement of the plurality of sub-regions (eg, the first sub-region 1731 and the second sub-region 1732 ). Some possible sub-regions can be re-identified. As illustrated in 1802 of FIG. 18 , when all of the plurality of sub-regions (eg, the first sub-region 1731 and the second sub-region 1732 ) are arranged in a horizontal direction, the electronic device 100 All of the plurality of sub-regions may be identified as having uncontrollable scan rates independently. In this case, the electronic device 100 may control the display driver IC 520 to display content in the plurality of sub-regions at a scan rate (eg, a first scan rate) corresponding to a parameter associated with the exposed region.

As described above, when a specified condition is satisfied (eg, a specified time elapses) after a sub-region is changed (eg, an area of a sub-region is changed, an arrangement of a sub-region is changed), the electronic device 100 changes the scan rate The display driver IC 520 may be controlled to display the raw content. For example, after the area of the first sub-region 1731 and/or the second sub-region 1732 is changed, the electronic device 101 does not display the content at the refresh rate corresponding to the changed area for a specified time, When a specified time elapses, the display driver IC 520 may be controlled to display content at a refresh rate corresponding to the changed area. Accordingly, the electronic device 101 may refrain from performing the operation of changing the scan rate in response to each of the plurality of area changes each time when the areas of the sub-regions are not changed at once but are changed a plurality of times. have. Even at this time, when the scan rate is changed stepwise as shown in FIG. 17C , the electronic device 101 may change the scan rate stepwise at a designated time interval for a designated time period as described above.

According to various embodiments, when the display 510 is slid while using the multi-window, the electronic device 100 may change the refresh rate set for each of the plurality of sub-regions. In an embodiment, the electronic device 100 identifies an identified refresh rate (eg, a second scan rate) based on a parameter associated with the changed exposed region of the display 510 , and a sub-region based on the identified second scan rate It is possible to identify a scan rate to be set for each field. For example, when the display 510 is further drawn out as shown in 1704 of FIG. 17A or the display 510 is further retracted as shown in 1705 of FIG. 17A, the electronic device 100 may display ( A parameter associated with an exposed area of the display 510 that is changed according to the withdrawal or retraction of the 510 may be identified. The electronic device 100 may identify changed scan rates (eg, a fourth sub scan rate and a fifth sub scan rate) to be set in the changed exposed region based on the identified parameter. The electronic device 100 determines the horizontal length sw2-1 of the sub-regions (eg, the first sub-region 1731 and the second sub-region 1732 ) that are changed according to drawing out or retracting of the display 510 . A second scan rate corresponding to sw2-2 or sw3-1 and sw3-2) and a length (W2 or W3) in the horizontal direction of the entire area of the drawn display 510 are identified, and based on this, a sub-region is identified. It is possible to identify a scan rate to be set for each field. Since the operation of identifying the scan rate to be set for each sub-region (eg, the first sub-region 1731 and the second sub-region 1732 ) of the electronic device 100 has been described above, a redundant description will be omitted.

Hereinafter, an example of an operation of the electronic device 100 according to various embodiments will be described.

According to various embodiments, the electronic device 100 may set the scan rate of a specific region corresponding to the occurrence of the specified event as a preset scan rate (eg, the highest scan rate) based on the occurrence of the specified event.

19 is a flowchart 1900 for explaining an example of an operation of the electronic device 100 according to various embodiments. According to various embodiments, the operations illustrated in FIG. 19 are not limited to the illustrated order and may be performed in various orders. In addition, according to various embodiments, more operations than those illustrated in FIG. 19 or at least one fewer operations may be performed. Hereinafter, FIG. 19 will be described with reference to FIG. 20 ( FIGS. 20A and 20B ).

FIG. 20A is a diagram for explaining an example of an operation of setting a specific area to a preset refresh rate when the display 510 of the electronic device 100 is drawn out (or drawn in) according to various embodiments of the present disclosure. 20B is a diagram for describing an example of an operation of setting a specific area to a preset refresh rate when using a multi-window of the electronic device 100 according to various embodiments of the present disclosure.

According to various embodiments, the electronic device 100 may identify occurrence of a specified event in operation 1901 , and set a scan rate of a region associated with the event generated in operation 1903 as a preset scan rate. For example, the occurrence of the designated event is to identify that the display 510 is drawn out (or drawn in (not shown)) as shown in FIG. 20A , or a refresh rate independently of a plurality of sub-areas when using a multi-window This may include receiving user input to select some sub-region that is controllable. Hereinafter, an operation of setting a scan rate of a specific area to a preset scan rate for each example of occurrence of a specified event of the electronic device 100 will be described.

According to various embodiments, when the display 510 is drawn out (or retracted), the electronic device 100 may set the scan rate of the specific region 2011 to a preset scan rate. For example, the specific area 2011 is an area (eg, the second area A2) (eg, the second area ( A2)), the entire area of the display 510, or a curved area corresponding to (eg, positioned on) a roller electronic device 100 (eg, movement detection module 563). can identify the occurrence of an event indicating that the display 510 is drawn out (or retracted) based on identifying the slide movement of the display 510 using a sensor (eg, hall-sensor) as described above. Based on the generated event, the electronic device 100 sets the scan rate of the specific region 2011 higher than the scan rate set before the occurrence of the event (eg, a scan rate identified based on a parameter associated with an externally exposed region). In an embodiment, the higher scan rate may be the highest scan rate (highest scan rate) among a plurality of preset scan rates previously stored in FIGS. 12 to 13. In this case, For a specified period of time from the occurrence of the event, the change of the refresh rate may not be performed or a specific refresh rate may be maintained. If the event is not completed, the original refresh rate will be maintained. A change operation may also be performed.

According to various embodiments of the present disclosure, as shown in FIG. 20B , the electronic device 100 receives a user input for selecting a sub-region whose refresh rate is independently controllable from among a plurality of sub-regions set according to the use of a multi-window. Based on this, the scan rate of a specific region (eg, some sub-regions whose scan rate is independently controllable selected by a user) may be set as a preset scan rate. For example, the electronic device 100 receives a user's input on the display 510 and corresponds to the received user's input among the plurality of sub-regions (eg, including a location where the user's input was received). A sub-region can be identified. The electronic device 100 may identify whether the identified sub-region is a region in which a scan rate is independently controllable. The operation of identifying a region in which the scan rate of the electronic device 100 is independently controllable is the same as described above in operation 1607 of FIG. 16 , and thus a redundant description will be omitted. For example, as shown in 2003 of FIG. 20B , the electronic device 100 receives a user input for selecting one sub-region 2032 among two sub-regions (eg, 2031 and 2032), and the selected one sub-region When the region 2032 has the control length L, one selected sub-region may be identified as an independently controllable region. Also, for example, as shown in 2004 of FIG. 20B , the electronic device 100 receives a user input for selecting one sub-region 2042 that cannot be independently controlled from among the three sub-regions 2041 , 2042 , and 2043 . When identified, one sub-region 2042 and adjacent (or contacted) sub-regions (eg, 2043 and 2041) are arranged side by side in the vertical direction and have a length corresponding to the control length L when summed Another sub-region 2043 may be identified, and the selected sub-region 2042 and the identified sub-regions 2043 may be identified as the independently controllable region 2044 . The electronic device 100 identifies that an event has occurred based on the identification of the independently controllable region according to a user input, and transfers the scan rate of the independently controllable region to the scan rate set before the occurrence of the event (eg, to the sub region). It can be set to a higher scan rate than the set scan rate). In an embodiment, the higher scan rate may be the highest scan rate (highest scan rate) among a plurality of preset scan rates previously stored in FIGS. 12 to 13 .

According to various embodiments, the electronic device 100 may set the existing refresh rate when the event generated in operation 1905 ends. For example, when the slide movement of the display 510 is completed, the electronic device 100 identifies the identified based on the parameter associated with the area exposed to the outside of the display 510 that is changed according to the slide movement of the display 510 . The scan rate of a specific area can be set as the scan rate. Also, for example, when a specified period has elapsed after the user input is released, the electronic device 100 may set the scan rate of the independently controllable region to the previously set scan rate. Meanwhile, the electronic device 100 performs a predetermined process (or maintains the focus) even if the user input is maintained or the user input is released (eg, content displayed in the corresponding area is played, text is input in the corresponding area) ), the scan rate of the independently controllable area can be maintained at a higher scan rate.
