For purposes of simplicity and illustration, this disclosure is mainly explained with reference to examples. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. It will be apparent, however, that the present disclosure may be practiced without being limited to these specific details. In other instances, some methods and structures have not been described in detail to avoid unnecessarily obscuring the disclosure.

Throughout this disclosure, the terms "a" and "an" are intended to mean at least one specific element. When used herein, the term "includes" means including but not limited to, and the term "includes" means including but not limited to.

Electronic devices, such as computing devices, may use rollable display panels to display image content. These rollable display panels include a plurality of pixels formed on a thin and flexible substrate, where the flexible substrate can include materials such as plastic, metal, or flexible glass. In this way, even when the rollable display panel may be bent, folded or rolled, the rollable display panel may be able to display desired image content without suffering damage. Examples of such rollable display panels include: flexible liquid crystal display panels, flexible plasma display panels, flexible e-ink display panels, flexible organic light-emitting diode panels, and flexible electrowetting Monitor panels, among others.

To transmit image content to the rollable display panel, the computing device may send data associated with the image content to a controller operatively connected to the rollable display panel. When there is a rollable touch display panel, the controller can send a signal associated with a contact at a location on the rollable touch display panel.

In an alternative use to a rollable display panel, a computing device may include a rollable display panel to enable multiple display sizes at the user's discretion. Therefore, the same computing device can have a range of display sizes, rather than having one screen with a fixed screen size. In order to resize an effective display panel size, the computing device may have to perform some rollback and expansion operations in order to increase/decrease an area on which image content is to be displayed. In some examples, some of these operations may imply the use of additional tools to remove fixed components to facilitate Resize the rollable display panel. For example, when the computing device is a laptop computer that includes a cover portion rotatably coupled to a base portion, the roll-up display panel configuration may be secured via a series of screws. In order to expand/reduce the effective display panel size, a user may have to use a tool to remove the screws, then the user may have to set the desired effective display panel size, and then put the screws back on the cover portion , to ensure that the integrity of the computing device is not affected by the resizing process.

Throughout this disclosure, the term "effective display panel size" is used to refer to the portion of a roll-out display panel on which image content is displayed to a user, that is, on which the user can view the The size of an area of image content.

Disclosed herein are examples of computing devices and methods for modifying an effective display panel size without the use of additional tools. Accordingly, different examples of computing devices and methods are described.

Referring now to FIG. 1A , a computing device 100 is shown that includes a rollable display panel 130 . The computing device 100 includes a base part 110, a cover part 120, and a rollable display panel 130, wherein the cover part 120 is rotatably coupled to the base part 110 via a hinge 140. The base portion 110 of the computing device 100 includes a track 111 extending along a length of the base portion 110, and a rotor 112 movable along the track 111. In the computing device 100 of FIG. 1A , the rotor 112 is parallel to a rotation axis defined by the hinge 140 . Therefore, a movement of the rotor 112 away from the hinge 140 may cause the rollable display panel 130 to be released a distance from the rotor 112 .

As explained previously, rollable display panels can be used to enable a range of effective display panel sizes without the use of additional tools to remove fixed components. In FIG. 1A , a first portion 131 of the roll-up display panel 130 is fixedly attached to an upper side of the cover portion 120 , and a remaining portion of the roll-up display panel 130 is wrapped around the rotor 112 . Therefore, the effective display panel size of the computing device 100 corresponds to the first portion 131 of the rollable display panel 130, that is, on the The user can see an area of the image content displayed on the rollable display panel 130 .

Referring now to FIG. 1B , the computing device 100 of FIG. 1A is shown with the rollable display panel 130 extending over the base portion 110 of the computing device 100 . As explained above, as the rotor 112 moves along the track 111 , the rotor 112 unwraps a second portion 132 of the roll-up display panel 130 .

In some examples, movement of rotor 112 along track 111 may be triggered by a triggering event. In response to the triggering event, the rotor 112 of the base portion 110 moves along the track 111 so that the rotor 112 unfolds the second portion 132 of the rollable display panel 130 . In order to unfold the second portion 132 of the rollable display panel 130 , the rotor 112 is rotated in an unwinding direction so that the rollable display panel 130 is released from a lower area of the rotor 112 . In one example, the trigger event may be received by a controller of the computing device 100 , and the controller may control an actuator located in the base portion 110 of the computing device 100 to move along the The track 111 moves the rotor 112 .

In some other examples, the base portion 110 of the computing device 100 may further include a biasing element for biasing the rotor 112 to the second position, and a locking member for locking movement of the rotor 112 . When a controller of the computing device 100 receives a trigger event, the controller controls the locking member to unlock the movement of the rotor 112 so that the rotor 112 moves to the second position. In other examples, the triggering event may include manually moving the rotor 112 along the track 111 (eg, a user may move the rotor 112 along the track 111 ).

Referring now to FIG. 2A , a computing device 200 including an opening 213 is shown. The computing device 200 includes a base part 210, a cover part 220 and a rollable display panel 230. The base portion 210 and the cover portion 220 are rotatably coupled via a hinge 240 (not visible in Figure 2A). In FIG. 2A , an upper side of the cover part 220 and an upper side of the base part 210 form an angle of 180 degrees.

The base portion 210 of the computing device 200 includes rails 211a and 211b, a rotor 212 and an opening. 213. The opening 213 located in a proximal area of the base portion 210 is used to receive the rotor 212 so that the rotor 212 does not protrude from the base portion 210 . In some examples, the position of the rotor 212 within the opening 213 may be called an initial position (or first position). In some other examples, the base portion 210 may further include a cover to close the opening 213 when the rotor 212 is located in the opening 213, wherein the cover may be between an open position and a closed position. move between.

In the example of FIG. 2A , the rollable display panel 230 includes a first portion 231 fixedly attached to the upper side of the cover portion 220 , and the remaining rollable display panel 230 is wound around the rotor 212 so as to effectively The display panel size corresponds to the first portion 231 of the rollable display panel.

In some other examples, computing device 200 may include a single track instead of tracks 211a and 211b. However, in order to balance the forces exerted by the rotor 212 and the rollable display panel 230 wrapped around the rotor 212, the use of the rails 211a and 211b increases the life of the mechanical connection structure.

Referring now to Figure 2B, the computing device 200 of Figure 2A is shown as the rotor 212 moves along one of the tracks 211a and 211b. Due to this movement, the rotor 212 has protruded from the opening 213 and moved to a second position. When moving from the initial position (shown in Figure 2A) to the second position (shown in Figure 2B), the rotor 212 unfolds a second portion 232 of the rollable display panel 230 so that the rollable display panel 230 can The roll display panel 230 covers an area of the base portion 210 . Specifically, the second portion 232 of the rollable display panel 230 is released from an upper area of the rotor 212 (that is, the rotor 212 must be rotated in a counterclockwise direction to unfold the rotor 212 Rollable display panel 230). For example, in FIG. 2B , the rollable display panel 230 partially covers a keyboard disposed on an upper surface of the base portion 210 . In some examples, movement of the rotor may be based on a trigger event. Examples of trigger events include both mechanical events and signal-based events.

In one example, in order to move the rotor 212 along the tracks 211a and 211b, the base portion 210 of the computing device 200 may include a motor. After receiving a trigger event, the motor can move the rotor 212. In one example, the motor may be mechanically connected to the rotor 212 via a transmission element such as a gear train or a belt. In other examples, the tracks 211a and 211b may include an actuator to move the rotor 212 in response to a triggering event. In some other examples, the rotor 212 may be manually positioned by a user.

In some examples, tracks 211a and 211b may include a slope along base portion 210 such that rotor 212 is at a different distance relative to base portion 210. In this way, when the rotor 212 moves along the rails 211a and 211b, the height difference caused by the reduced radius of the rotor 212 and the roll-up display panel 230 on the rotor can be compensated. In one example, the highest position of the rotor 212 is at a distal end of the base portion 210 , and the lowest position of the rotor 212 is at a proximal end of the base portion 210 . In other words, the lowest position of the rotor 212 corresponds to a rotor position in which the amount of the roll-up display panel 230 on the rotor 212 is at its maximum, and the highest position of the rotor 212 corresponds to a position in which the roll-up display panel 230 on the rotor 212 is at its maximum. The volume of the rollable display panel 230 is at its minimum corresponding to a rotor position.

As explained with reference to other examples, movement of the rotor 212 along the track causes the rotor 212 to unfold the second portion 232 of the roll-up display panel 230 . In some examples, the base portion 210 of the computing device 200 may include a sensor to determine an unlocked state associated with a distance at which the rollable display panel 230 is released from the rotor 212, and based on the unlocked state to display an image content on the rollable display panel 230. For example, in the computing device 200 of FIG. 2B , a distance of the rollable display panel 230 is still wrapped around the rotor 212 . Therefore, this distance of the rollable display panel 230 may not be used to present image content. Specifically, the effective display panel size in which image content can be presented is defined by the first portion 231 of the rollable display panel 230 and the second portion 232 of the rollable display panel 230 .

Referring now to Figure 3A, a side view of a computing device 300 is shown. The computing device 300 includes a base portion 310 that is rotatably coupled to a cover portion 320 via a hinge assembly 340 . the The base portion 310 of the computing device 300 includes a rotor 312 that can move along a track of the base portion 310, and an opening 313. In FIG. 3A , the rotor 312 is in an initial position, in which the rotor 312 is secured within the opening 313 so that the rotor 312 does not protrude from an upper surface of the base portion 310 .

To enable multiple effective display panel sizes for the computing device 300, the computing device 300 includes a rollable display panel 330. Specifically, in FIG. 3A , a first portion 331 of the rollable display panel 330 is disposed on an upper side of the cover portion 320 . In one example, the first portion 331 of the rollable display panel 330 may be fixedly attached via a series of securing elements distributed along the length and width of the cover portion 320 . In FIG. 3A , in addition to the first portion 331 , the rollable display panel 330 is rolled around the rotor 312 by a distance such that movement of the rotor 312 along one of the base portions 310 can cause the rollable display panel 330 to roll around the rotor 312 . A second portion of the display panel 330 is released from the rotor 312 .

In the computing device 300 of FIG. 3A , the cover portion 320 is coupled to the base portion via a hinge assembly 340 . In some examples, the hinge assembly 340 may include a locking member to lock a rotation of the cover portion 320 relative to the base portion 310 . In one example, the rotation may be locked when the cover portion 320 and the base portion 310 form an angle of 180 degrees. In order to determine the angle between the cover portion 320 and the base portion 310, the hinge assembly 340 may further include a sensor. However, in other examples, the hinge locking members of the hinge assembly 340 may include a series of locking positions along an angular range. In one example, the locking member may include a locking feature to automatically lock the rotation when an angle of 180 degrees between the cover portion 320 and the base portion 310 is reached.

Referring now to FIG. 3B , the computing device 300 is shown in a second position. When in the second position, the locking member of the hinge assembly 340 has locked the rotation of the cover part 320 relative to the base part 310 . In the example of FIG. 3B , the rotor 312 has protruded from the opening 313 of the base portion 310 and moved along the path indicated by the dotted line. As a result of this movement, a second portion 332 of the roll-up display panel 330 has been released from the rotor 312 . In one example, a movement of the rotor 312 along the track of the base portion 310 The dynamic system causes the rotor 312 to rotate in the unwinding direction, so that the rollable display panel 330 wrapped around the rotor 312 is released. In the example of FIG. 3B , the unlocking direction corresponds to the counterclockwise direction.

As explained above, the image content to be presented on the rollable display panel 330 may be determined based on a current position of the rotor 312 relative to an initial position (eg, the initial position shown in FIG. 3A ). In order to determine the position of the rotor 312, the base portion 310 of the computing device 300 includes a sensor 314. In one example, the sensor determines a distance relative to the rotor 312 and determines an unlocked state based on the determined distance. Then, based on the unfolded state, the image content to be displayed on the rollable display panel 330 is modified so that the user can see the first portion 331 along the rollable display panel 330 and the rollable display Image content extending from the second portion 332 of the panel 330 (ie, the remainder of the rollable display panel 330 surrounding the rotor 312 may not be able to display image content).

Referring now to Figure 3C, a side view of a computing device 300C is shown in a second position 312C. The computing device 300C includes a base portion 310 that is rotatably coupled to a cover portion 320 via a hinge assembly 340. In the computing device 300C, a first position 312A in which the rotor 312 is located in a proximal end of the base portion 310, a path from the first position 312A to the second position 312C and the transmission element 315 are represented by dotted lines. express.

In order to move the rotor 312 from the first position 312A to the second position 312C, the base portion 310 includes a transmission element 315 . In one example, the transmission element 315 corresponds to a belt that is mechanically connected to the rotor 312 such that the rotor 312 moves along the track of the base portion 310 when the belt is moved, such as by an actuator. As explained previously, movement of the rotor 312 may be triggered upon receipt of a trigger event. In one example, when a trigger event is received, an actuator located in the base portion 310 of the computing device 300C moves the transmission element 315 so that the rotor 312 moves from the first position 312A to the second position. 312C. In some examples, the triggering event may be an angular position between the cover portion 320 and the base portion 310 . Then, when an angle between the cover part 320 and the base part 310 is equal to a critical angle, the movement of the rotor 312 along the track of the base part is performed. In a In one example, the relative position between the cover portion 320 and the base portion 310 may be measured using a sensor located in the hinge assembly 340 .

In the second position 312C of the rotor 312, a second portion 332 of the rollable display panel 330 has been released from the top of the rotor 312. Therefore, the rollable display panel 330 covers an upper surface of the base portion 310 of the computing device 300C. In some examples, in order to lock the second portion 332 of the rollable display panel 330, the rotor 312 may include a torsion element (not shown in FIG. 3C) to apply a torque in a rolling direction. (In Figure 3C, the winding direction corresponds to a clockwise direction). In one example, the torsion element can be a spring. Therefore, although the rotor 312 has released the second portion 332 of the rollable display panel 330, the second portion 332 may not be released.

Although the computing devices 100, 200, 300 and 300C previously explained in FIGS. 1A to 3C include rollable display panels 130, 230 and 330, it should be noted that in other examples, the rollable display panels Alternatively, a display assembly may be provided which includes a fixed display panel on an upper side of the cover portion and a rollable display panel wrapped around a rotor movable along a track of the base portion, wherein the retractable display panel One edge of the roll display panel is attached to the fixed display panel. In this manner, instead of a rollable display panel including a first portion and a second portion of the rollable display panel, the computing device can include two different displays: a fixed display panel and a rollable display panel. Since rollable display panels are more expensive than fixed display panels, having two different displays reduces the overall cost of the display assembly. On the other hand, when a single rollable display panel is used, continuity of image content along the rollable display panel is easier than with a display assembly containing two separate display panels.

According to some examples, the track of the base portion of the computing device may be tilted to compensate for the height difference caused by releasing the rollable display panel. Therefore, the second portion of the roll-up display panel uncoiled from the rotor can remain flat even though the radius of the roll-up display panel on the rotor has been reduced.

Referring now to Figure 4, a detailed view of a computing device 400 is shown. The computing device 400 includes a base portion 410 rotatably coupled to a cover portion 420 with a first portion 431 of a rollable display panel 430 attached to an upper side of the cover portion 420 . For illustrative purposes, one lateral side of the base portion 410 is not shown so that elements contained in the base portion 410 are visible in FIG. 4 .

The base portion 410 of the computing device 400 includes a rotor assembly 412 for moving along a track (not shown in FIG. 4 ) of the base portion 410 . The rotor assembly 412 includes a rotor on which the rollable display panel 430 is wound. In addition, the base portion 410 includes a transmission element 415 and a locking member 416 for locking the movement of the rotor assembly 412 along one of the rails. In one example, the transmission element 415 is operably connected to an actuator (eg, a motor) in the base portion 410 such that the transmission element 415 transmits movement from the actuator to the rotor assembly 412 . In other examples, the base portion 410 does not include an actuator, and the transmission element 415 can control a movement operation when moving the rotor assembly 412 along the track of the base portion 410 .

In the computing device 400 of FIG. 4 , the locking member 416 is used to lock a movement of the rotor assembly 412 . In one example, the locking member 416 can lock the movement when the rotor assembly 412 exceeds a critical speed. In other examples, the locking member locks the movement of the rotor assembly 412 until a trigger event is received.

Although the locking member 416 of the computing device 400 of FIG. 4 is connected to the transmission element 415, in other examples, alternative positions may be possible. In one example, the locking member 416 may be positioned in the rotor assembly 412 such that the locking member 416 unlocks a portion of the track of the rotor assembly 412 along the base portion 410 when receiving a triggering event. Move.

Referring now to FIG. 5, a detailed view of a base portion 510 of a computing device 500 is shown. The base portion 510 includes a track 511 extending along a length of the base portion 510 . In addition, the base portion 510 includes a rotor assembly 512 movable along the track 511, wherein the rotor assembly 512 contains a gear train.

As previously explained, a second portion 532 of a roll-up display panel 530 unfolds from a top region of the rotor of the rotor assembly 512 as the rotor assembly 512 moves along the track 511 of the base portion 510 . In the example of FIG. 5 , the rotor assembly 512 includes a gear-based connection structure to maintain locking of the second portion 532 after the second portion 532 is released. The gear-based connection structures include a counter gear assembly coupled to the rotor of the rotor assembly 512 and to the track 511 . In one example, the track 511 corresponds to a gear track, wherein the reverse gear assembly of the rotor assembly 512 is mechanically connected to the gear track and the rotor of the rotor assembly 512 such that the rotor assembly A movement of 512 from a first position to a second position a distance away from the first position causes the rotor of the rotor assembly 512 to move in an unwinding direction (counterclockwise direction in Figure 5). Rotate. In other words, a movement of the rotor assembly 512 away from the initial position can proportionally release the second portion 532 of the roll-up display panel.

Referring now to FIG. 6 , a detailed view of a base portion 610 of a computing device 600 including an actuator 619 is shown. For illustrative purposes, one lateral side of the base portion 610 is not shown so that internal components in the base portion 610 are visible.

The base portion 610 of the computing device 600 of Figure 6 includes a gear track 611, a rotor assembly 612, a transmission element 615, a locking member 616, and an actuator 619. The rotor assembly 612, which is similar to the rotor assembly 512 of the computing device 500 of Figure 5, includes a counter gear assembly, a rotor, the locking member 616, and a torsion element 618 coupled to the rotor ( Indicated by dashed lines). In the example of Figure 6, the torsion element 6218 corresponds to a spring. However, in other examples, other elements capable of recovering size and shape after a deformation may be used. The reverse gear assembly of the rotor assembly 612 converts a linear movement of the rotor assembly 612 into a rotation of the rotor. Next, if the rotor assembly 612 moves away from its initial position of the rotor in which the second portion 632 is completely wrapped around the rotor assembly 612, the reverse gear assembly can convert this movement into a movement in the unwinding direction. rotation, which can result in a rollable display panel 630 The second part 632 is released. As previously explained, the twisting element 618 can be used to lock the second portion 632 of the rollable display panel 630 . Therefore, although the amount of release of the roll-up display panel 630 from the rotor results in a reduction in the rotor radius, which can cause the second portion 632 of the roll-up display panel 630 to loosen, the twisting element 618 is The rotor is biased in a winding direction in order to compensate for the difference caused by the reduction in radius. In one example, the twisting element 618 applies a torque in a rolling direction (clockwise direction in FIG. 6 ), so that the second portion 632 of the rollable display panel is locked.

To move the rotor assembly 612 along the gear track 611 of the base portion 610, the computing device 600 includes an actuator 619. In one example, the actuator 619 can be a motor. In order to transmit the movement of one of the actuators 619 to the rotor assembly 612, the rotor assembly 612 is attached to a transmission element 615. Therefore, when a triggering event occurs, the actuator 619 moves the transmission element 615 such that the movement causes a linear movement of the rotor assembly 612 along the gear track 611 of the base portion 610 .

In some examples, gear track 611 may be tilted such that the rotor systems of rotor assembly 612 are at different heights relative to base portion 610 as rotor assembly 612 moves along gear track 611 . In this manner, the decrease/increase in radius caused by rolling/unrolling of the rollable display panel can be compensated in order to keep the second portion 632 of the rollable display panel 630 flat.

As explained previously, the locking member may be used to lock a movement of the rotor assembly 612 along the gear track 611 .

In some examples, the position of the stand topographical body 750 may be controlled based on an unfolded state associated with a second portion 732 of the rollable display panel of the computing device 700 . For example, based on a position of a rotor relative to base portion 710 , the support topography 750 can be removed from the base portion 710 The surface 710B protrudes. In one example, the position of the stent topography 750 can be controlled based on a stent topography expansion signal sent by the controller of the computing device 700 . In response to the stent topology deployment signal, the actuator 752 is used to move the stent topography 750 to the deployment position.

Although the stand feature 750 of the computing device 700 of FIGS. 7A and 7B is located on the surface 710B of the cover portion 720, it should be understood that other alternative positions may be possible, such as on one of the lateral sides of the base portion 710. a bracket topography 750 on a surface of the cover portion 720 of the computing device 700 .
