Fig. 1 is a schematic diagram of a multi-screen display system 100 according to an embodiment of the present application, as shown in fig. 1, the multi-screen display system 100 includes a display control device 110, a first display screen 121, and at least one second display screen 122, where the display control device 110 may be connected to the first display screen 121 and the at least one second display screen 122, respectively. In fig. 1, only 3 second display screens 122 are taken as an example, and the number of second display screens is not limited.
Optionally, one of the first display screen 121 and the at least one second display screen 122 is a main display screen (hereinafter, referred to as a main screen), and the others are sub display screens (hereinafter, referred to as sub screens). For example, the first display screen 121 may be a main screen and the second display screen may be a sub-screen.
Alternatively, the display control apparatus 110 may be independent of any display screen; or the display control apparatus 110 may be disposed on the same device (e.g., a first display device) as the primary screen (e.g., the first display screen 121) and connected to the secondary screen (e.g., the at least one second display screen 122).
Alternatively, the device (for example, the first display device) disposed with the display control apparatus 110 may be signal-transmitted and spliced with the display device (for example, the second display device) disposed with the second display screen through a high-definition multimedia interface (High Definition Multimedia Interface, HDMI) line.
Alternatively, the first display screen 121 and the second display screen 122 may be the smart interactive tablet, and the display control device 110 may be integrated with the first display screen 121 and/or the second display screen 122.
In the multi-screen display system, different display screens can be cooperatively displayed according to a copy mode or an expansion mode. In the copy mode, each display displays the same content, for example, window one is displayed in the display interfaces of the first display and the second display in fig. 2 a; in the extended mode, the contents displayed by the display screens are different, for example, a complete picture can be cooperatively presented, or respective display interfaces are opened, for example, a first display window is displayed in the display interface of the first display screen in fig. 2b, and a second display window is displayed in the display interface of the second display screen.
In the above expansion mode, the opened application window is displayed in one display screen, for example, the application window is displayed in the main display screen by default, when other display screens need to display the application window, the application window of the main screen needs to be "dragged" to the auxiliary screen, and in combination with the illustration of fig. 3a, the application window in the first display screen is moved to the second display screen, and the application window needs to be dragged to the second display screen; similarly, when an application window displayed in one display screen needs to be displayed across screens, one side or a corner of the application window needs to be "stretched" to the other display screen, and in combination with fig. 3b, the application window of the first display screen is stretched to the second display screen.
However, in a large indoor or outdoor space of a venue, the size of each screen is large, the application window of the main screen is dragged to the auxiliary screen, or the main screen window is stretched to the auxiliary screen, the path of cursor movement is long, the operation time is long, the application window is easy to separate from the cursor control in the dragging process, and the operation efficiency of displaying the application window by the auxiliary screen is low.
Aiming at the problem of low control efficiency of an application window in the double-screen or multi-screen display scene, the embodiment of the application provides the following three possible solutions: according to the scheme I, the display control device judges the moving speed of an application window in a display interface of a first display screen along with a dragging operation, and whether the application window is moved to a second display screen or not is determined; the second scheme is that the display control device opens an application window displayed in the display interface of the main screen on the second display screen after determining that the selection operation of the function control is received through the display interface of the second display screen; according to the third scheme, the display control device determines the aspect ratio of the application window to be displayed, and when the aspect ratio of the application window to be displayed exceeds the aspect ratio of the first display screen, the application window is displayed together according to the aspect ratio of the application window to be displayed through the first display screen and the second display screen.
The multi-screen display method provided by the present application is described below by way of several embodiments.
It should be understood that the execution subject of the embodiments of the present application may be a display control device, such as the display control device 110 in fig. 1 described above. The display control device may be an independent electronic device, for example, an electronic device with a display control device disposed thereon is connected to the first display screen and the at least one second display screen, and controls the first display screen and the at least one second display screen to display, and the electronic device may be, for example, a smart interactive tablet, a smart television, a smart screen, a mobile phone, a computer, or the electronic device may be a server; or the display control device and the first display screen can be disposed in the same electronic equipment, for example, the electronic equipment with the display control device and the first display screen disposed is connected with at least one second display screen, the display control device controls the first display screen and the at least one second display screen to display, and the electronic equipment can be, for example, an intelligent interaction tablet, an intelligent television, an intelligent screen, a mobile phone, a computer and the like. The electronic device in which the display control apparatus is disposed may be a chip, a processor, or the like.
Alternatively, the connected display screen may be an electronic device having only a display function, or may be a terminal device having a display function, such as a smart tablet, a smart television, a smart screen, a mobile phone, a computer, or the like.
Fig. 4 is a schematic flow chart of a multi-screen display method 200 provided in an embodiment of the present application, and the multi-screen display method 200 shown in fig. 4 includes all or part of the following procedures.
S210: responding to the dragging operation of a user on a first window in a display interface of the first display screen, determining a first speed, wherein the first speed is determined based on the speed of the first window in a first displacement, and the first displacement is a displacement of a preset length before a stopping position of the dragging operation;
s220-1: and if the speed of the first window in the first displacement is greater than or equal to a preset value, moving the first window from the display interface of the first display screen to the display interface of the second display screen.
S220-2: and if the speed of the first window in the first displacement is smaller than a preset value, displaying the first window at a stop position of the dragging operation.
It should be noted that the first window may be an application window displayed in the display interface of the first display screen. For example, after the user operates to open the first window, the first window is displayed in the first display screen by default.
Optionally, the display interface of any display screen is an interactive interface, the user can input instructions through touch operation or mouse operation in the interactive interface, and for the display control device, a cursor (including an implicit cursor or a display cursor) can be generated at the touch position or the mouse operation position of the user, and the user operation can be acquired and identified through the cursor.
When a user drags a first window in a display interface of a first display screen, the display control device can determine information such as a path, time and the like of a dragging operation according to movement of a cursor in the dragging operation process, and determine whether to move the first window from the display interface of the first display screen to the display interface of a second display screen based on the information of the dragging operation.
It should be noted that, the first displacement is a displacement of a preset length before the stop position of the drag operation, that is, a displacement of the "tail" of the drag operation, and the first speed may be understood as an instantaneous speed of the "tail" of the drag operation.
If the first speed is greater than or equal to the preset value, it indicates that the speed of the movement of the drag operation of the user is relatively high, as shown in fig. 5, for example, the first window may be understood as "flicking" in this case, and the first window may be moved from the display interface of the first display screen to the display interface of the second display screen.
Alternatively, the first window may be moved to a center position of the display interface of the second display screen.
Optionally, when the first window is moved from the display interface of the first display screen to the display interface of the second display screen, the moving display effect is not limited in the embodiment of the present application. For example, the first window may display a display interface that moves to the second display screen, e.g., the first window flies from the display interface of the first display screen into the display interface of the second display screen, or the first window may implicitly move to the display interface of the second display screen. When the first window implicitly moves from the display interface of the first display screen to the display interface of the second display screen, the moving dynamic effect is not displayed, namely the first window is not displayed from the display interface of the first display screen and is displayed in the display interface of the second display screen at the same time, or the first window gradually disappears from the display interface of the first display screen and is gradually displayed in the display interface of the second display screen.
It will be appreciated that the display control means may move the first window to each of the at least one second display, or may determine one or more target displays from the at least one second display, and move the first window to one or more target displays (how to determine target displays is explained in detail below).
If the first speed is less than the preset value, it indicates that the movement speed of the drag operation of the user is slower, for example, as shown in fig. 3a, in this case, the first window may move along with the drag operation, specifically, may move along with the cursor corresponding to the drag operation, and after the drag is finished, the first window stops moving, and the first window may move on the first display screen or may move to any second display screen.
Alternatively, the first speed may be the maximum speed of the first window in the first displacement, or the first speed may be the average speed of the first window in the first displacement.
Alternatively, the preset value may be 2 pixels per millisecond (px/ms).
In some embodiments, the display control apparatus moving the first window from the display interface of the first display screen to the display interface of the second display screen may include: the display control device determines a target display screen from at least one second display screen according to the displacement direction of the dragging operation, the position direction of the target display screen relative to the first display screen is the same as the displacement direction of the dragging operation, and the display control device moves the first window from the display interface of the first display screen to the display interface of the target display screen.
As shown in fig. 6, a second display screen is respectively arranged above, right and upper right of the first display screen. The displacement direction of the drag operation (namely, the displacement direction of the cursor corresponding to the drag operation) is the upper right side of the first display screen, the display control device determines that the target display screen is the second display screen positioned at the upper right side of the first display screen in the three second display screens, and then the display control device moves the first window from the display interface of the first display screen to the display interface of the second display screen positioned at the upper right side.
In some embodiments, the user may "flick" the plurality of application windows displayed in the display interface of the first display screen to the second display screen in sequence, respectively, through a plurality of drag operations. Then, before the first window is "flicked" to the second display, there may already be at least one second window in the display interface of the second display that is "flicked" by the first display. But this is only an example of the second window and does not constitute any limitation on the second window. For example, the second window of the second display may also be moved to the second display at a constant speed by the display device of the first display, or the second window may also be displayed by default by the second display.
In the scene where the second display screen has displayed at least one second window, the S220-1 may include: and superposing and displaying the first window above the second window in a mode of not shielding the window control.
For example, as shown in fig. 7, the first window is displayed above the second window in a superimposed manner with the upper right corner of the second window at the top of the display interface as a reference point, without blocking the window control of the second window.
As shown in fig. 7, when a plurality of application windows automatically move from the first display screen to the second display screen, each application window, for example, the plurality of second windows and the plurality of first windows in fig. 7, are sequentially overlapped by shielding with the upper right corner as a reference point according to the sequence.
Therefore, in this embodiment, the display control device determines whether to quickly move the first window in the display interface of the first display screen to the display interface of the second display screen by determining the first speed of the drag operation, so that compared with the case that the user moves the first window to the second display screen in a drag manner, the operation efficiency of displaying the first window on the second display screen is improved.
Fig. 8 is a flowchart of a multi-screen display method 300 according to an embodiment of the present application, where the method 300 includes at least part of the following procedures:
S310, acquiring a selection operation of a user on a first control in a function menu sub-interface, wherein the function menu sub-interface is displayed on a display interface of the second display screen, and the first control corresponds to a first window in the display interface of the first display screen;
s320-1, responding to the selected operation, and controlling a display interface of the second display screen to display the first window;
s320-2, responding to the selected operation of the first control, and controlling the display interface of the first display screen not to display the first window.
Illustratively, the display interfaces of each display (including the first display or either the second display) include a function menu list interface. When the first window is displayed in the display interface of the first display screen, a first control is displayed in the function menu list interface in the display interface of any second display screen, and the first control corresponds to the first window. And the first control in the display interface of any display screen has the functions of: and displaying the first window on a display interface of the current display screen.
The user may perform a selection operation on the first control in the display interface of any of the second display screens, for example, touching the first control, clicking the first control through a mouse, or the like. The display control device responds to the selected operation, namely, the first window is displayed in the display interface of the current second display screen.
Optionally, when the display control device displays the first window on the display interface of the second display screen by responding to the selection operation of the first control, the display control device may also respond to the selection operation of the first control and control the display interface of the first display screen not to display the first window. Of course, the display interface of the first display screen may still continue to display the first window, which is not limited in this application.
In some embodiments, as shown in connection with fig. 9a, in a display screen where the first window is not displayed, the function menu sub-interface may be collapsed and a floating window (e.g., a hover ball) may be displayed, which expands into the function menu sub-interface when the user moves the cursor to the floating window control (i.e., performs a selection operation on the floating window control) by operation, see fig. 9b. Further, the user may click the first control in the function menu sub-interface, that is, select the first control, and after receiving the selection operation of the user on the first control, the display control device displays the first window in the second display screen. Alternatively, the first window in the first display may be closed. See fig. 9c.
Alternatively, the function menu sub-interface may be displayed in the form of a sidebar.
In other words, the display control device may obtain a selection operation of the floating window control by the user, and display the sidebar display window on which the function menu sub-interface is displayed on the display interface of the second display screen in response to the selection operation. Further, the display control device may receive a selection operation of the user on the first control at the function menu sub-interface, and control the display interface of the second display screen to display the first window.
Therefore, in this embodiment, the display control device obtains the selection operation of the user on the first control by the function menu sub-interface of the second display screen, so that the first window displayed on the display interface of the first display screen is displayed on the display interface of the second display screen.
Fig. 10 is a flowchart of a multi-screen display method 400 according to an embodiment of the present application, where the method 400 includes at least part of the following procedures:
s410, acquiring a first operation of a user on a first window in a display interface of the first display screen, wherein the first operation is used for changing the aspect ratio of the first window into a target aspect ratio;
S420, responding to the first operation, and if the target length-width ratio is greater than or equal to the length-width ratio of the first display interface, displaying the first window on the display interface of the first display screen and the display interface of the second display screen in a cross-screen display mode according to the target length-width ratio.
For the above S410, it should be noted that the window control of the first window may include a window proportional control, and the display control device may obtain a selection operation (i.e., a first operation) of the window proportional control by the user, where a proportion corresponding to the window proportional control is a target aspect ratio example; or the display control means may acquire a window ratio (i.e., a first operation) input by the user, the window ratio being the target aspect ratio, and so on.
It should be noted that, in S420, if the target aspect ratio of the first operation instruction is greater than the aspect ratio of the first display screen, it means that the first window cannot be displayed with better display effect when the first window is displayed maximally. In this case, the display control device displays the first window on the display interface of the first display screen and the second display screen in a cross-screen display manner according to the target aspect ratio. For example, the display control device may display the first window on the display interfaces of the first display screen and the one second display screen in a cross-screen display manner, or may display the first window on the display interfaces of the first display screen and the plurality of second display screens, which is not limited in this embodiment.
Alternatively, the target aspect ratio may be an aspect ratio of the content to be displayed in the first window.
For example, in conjunction with fig. 11a, the aspect ratio of the first display screen is 16:9, and the display control device obtains the target aspect ratio of 32:9 in response to the user selecting the window proportional control (32:9 control), then in conjunction with fig. 11b, the display control device may stretch the first window displayed in the display interface of the first display screen to the display interface of the second display screen, and the second display screen and the first display screen together complete the display of the first window.
Optionally, after the first window is "stretched" to the second display screen, the content displayed in the first window may be scaled from the isocratic center to the center position of the window.
Optionally, after the first window is displayed in a stretched state on the display interfaces of the first display screen and the second display screen, the display control device may exit the stretched state of the first window in response to the second operation of the user, for example, resume the display of the first window on the display interface of the first display screen. Alternatively, the second operation may be a double-click operation input by the user at any position of the display interface of the first display screen or the second display screen, or may be a selection operation of exiting the full-screen control by the user at the display interface of the first display screen or the second display screen.
Therefore, in this embodiment, the display control device obtains the selection operation of the window proportional control in the display interface of the first display screen, or the target aspect ratio of the first window input by the user, and when the target aspect ratio is greater than or equal to the aspect ratio of the first display interface, the first window can be quickly displayed on the display interface of the first display screen and the display interface of the second display screen in a cross-screen display manner according to the target aspect ratio. Compared with the method that a user is required to 'stretch' one side or one corner of the first window from the display interface of the first display screen to the display interface of the second display screen, the operation efficiency of the first window is improved.
