[0032] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0033] The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0034] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] Next, combine Figure 1-Figure 2 The steps of the screen display method provided in the embodiment of the present application are described in detail.

[0036] See also Figure 1 , which is a flow chart of a screen display method provided in an embodiment of the present application, may include the following steps:

[0037] S101, obtaining active window information on each screen;

[0038] Among them, the active window information includes a virtual screen identifier, which is used to mark the virtual screen on which the active window is displayed. The active window displayed on the virtual screen carries the virtual screen identifier. Each screen corresponds to a virtual screen. The virtual screen carries a default identifier for distinguishing each virtual screen. The default identifier of the virtual screen is consistent with the virtual screen identifier of the virtual screen. The active window is one or more interfaces displayed on the screen.

[0039] For example, after the terminal is started and before any application is opened, there is only one active window A on screen 1, that is, desktop interface A' displayed on the screen after the terminal is started. Clickable application icons are displayed on active window A. When any application A on the desktop is opened by clicking the application icon, an interface B' showing the content related to application A will be generated, that is, active window B; if the content displayed by interface B' changes after clicking the content displayed by active window B, that is, the content displayed by active window B changes, or if interface C' is generated after clicking the content displayed by active window B, then this interface C' is active window C, or if interface C' is no longer displayed, that is, active window C is closed. The virtual screen contains the information and display content of the screen, that is, if there are 3 active windows displayed on screen 1, then virtual screen 1 contains the display information of the 3 active windows on screen 1, and each virtual screen corresponds to one screen, that is, virtual screen 1 corresponds to screen 1, and virtual screen 2 corresponds to screen 2. Any virtual screen carries a default identifier, and the default identifiers carried by each virtual screen are different, which are used to distinguish each virtual screen. In the initial state when the terminal is started, the virtual screen identifier carried by the virtual screen is consistent with the default identifier, and the virtual screen identifier is used to mark the virtual screen displayed by the active window; any active window displayed on the virtual screen carries the virtual screen identifier of the virtual screen. If the virtual screen identifier of virtual screen 1 is 1, then the active windows displayed on virtual screen 1 carry the virtual screen identifier 1.

[0040] In a possible implementation, the terminal or system obtains the active window information of each screen. Among them, the terminal is an entity on the user side that includes one or more display screens for receiving or transmitting signals, and can also be called a user client or user equipment (User Equipment, referred to as UE). It can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on the water surface (such as on a ship, etc.); it can also be deployed in the air (for example, on an airplane, a balloon, and a satellite, etc.). It can also be called a user terminal, a terminal device, an access terminal device, a vehicle-mounted terminal, a UE unit, a UE station, a mobile station, a mobile station, a remote station, a remote terminal device, a mobile device, a UE terminal device, a mobile terminal, a wireless communication device, a UE agent or a UE device, etc. The terminal can be fixed or mobile, etc. Its specific form can be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver function, a vehicle-mounted terminal device, a wireless terminal in a smart home, a wearable terminal device, etc. The system can be composed of two or more terminals connected as mentioned above. It should be noted that the connection method includes but is not limited to making the terminals in the system in the same local area network environment or connecting via data cables, and the embodiments of the present application do not impose any limitations.

[0041] S102, changing the virtual screen identifier of the virtual screen to be switched according to the first switching operation of the user on the screen to be switched among the screens, and sending the active window carrying the target virtual screen identifier to the virtual screen to be switched for display.

[0042] In a possible implementation, the active windows of each virtual screen are mapped into layers, the layers correspond to the active windows one by one, the virtual screen identifier of the layer is consistent with the virtual screen identifier of the corresponding active window, the layer carries layer sequence number information, and the layer sequence number information is used to determine the order in which the active windows corresponding to the layer are displayed on the virtual screen; the layers are summarized and stored.

[0043] For example, the virtual screen identifier of virtual screen 1 corresponding to screen 1 is 1, and active window A and active window B are displayed on screen 1, then active window A and active window B are displayed on virtual screen 1, and the virtual screen identifiers of active window A and active window B displayed on screen 1 and virtual screen 1 are both 1, the virtual screen identifier of virtual screen 2 corresponding to screen 2 is 2, and active window C, active window D and active window E are displayed on screen 2, then active window C, active window D and active window E are displayed on virtual screen 2, and the virtual screen identifiers of active window C, active window D and active window E displayed on screen 2 and virtual screen 2 are both 2, active window A-active window E are mapped to layer a-layer e, and the virtual screen identifiers carried by layer a and layer b is 1, and the virtual screen identifier carried by layer c, layer d and layer e is 2; the layer sequence information of layer a-layer e is determined by the order in which the corresponding active windows are displayed on the virtual screen. For example, if the order in which active window C-active window E is displayed on the virtual screen is active window C, active window D, active window E, and active window C is displayed on the top layer of virtual screen 2, then the layer sequence information of layer c, layer d and layer e is arranged in ascending order of sequence number 1, sequence number 2 and sequence number 3, indicating the order of display, and layer c is located at the top layer, or, the layer sequence information of layer c-layer e is arranged in descending order of sequence number 3, sequence number 2 and sequence number 1, indicating the order of display, and layer c is located at the top layer, and the embodiment of the present application does not make any limitation. The method for determining the order in which the active windows are displayed can be the reverse order of the order in which the active windows are generated. For example, active window A is generated first in screen 1, and then active window B is generated. Then the order in which the active windows are displayed on the screen is active window B, active window A, and active window B is located on the upper layer of active window A.

[0044] Aggregating and storing layers means aggregating and storing the layers corresponding to the active windows on each virtual screen. When aggregating the layers, the layers can be arranged in a queue according to the Z-order method. The Z-order method is used to set the display order. The display order is determined by setting the Z-axis value of the layer. The larger the Z-axis value, the higher the display layer is. For example, the specific implementation method of aggregating the layers in the above example and arranging them into a queue according to the Z-order method is to obtain the layer sequence information of each layer, first obtain layer a and layer b carrying the virtual screen identifier 1, since layer b is located above layer a, the Z-axis value of layer a is set to 1, and the Z-axis value of layer b is set to 2, and then obtain layers c-layer e carrying the virtual screen identifier 2, since layer e is located below layer d, and layer d is located below layer c, the Z-axis value of layer e is set to 3, the Z-axis value of layer d is set to 4, and the Z-axis value of layer c is set to 5; or, first obtain layer c, layer d and E carrying the virtual screen identifier 2 and set their Z-axis values ​​to 3, 2, and 1 respectively, then obtain layer a and layer b carrying the virtual screen identifier 1 and set their Z-axis values ​​to 4 and 5 respectively. If there are more virtual screens and layers, the Z-axis values ​​of the layers are set using the above Z-order method, which will not be repeated here.

[0045] It should be noted that after each layer is stored, the layer information will be updated in real time according to the changes of the active window displayed on the screen. For example, when the active window A on screen 1 is closed, the stored layer a will no longer exist; when the display content of the active window A on screen 1 changes, the display content of layer a will also change accordingly, that is, the layer is always consistent with the corresponding active window.

[0046] It should be noted that, if we call the content displayed before the screen to be switched receives the first switching operation the original content of the screen to be switched, and the content displayed after receiving the first switching operation is called the synchronized content of the screen to be switched, after the screen to be switched receives the first switching operation, the original content is not closed or disappears, but is hidden or replaced, and the original content will be recorded in the layer before being hidden or replaced, and the original content recorded in the layer will not change, and after receiving the first switching operation, the content displayed on the screen to be switched is displayed synchronously with the content displayed on the target screen. For example, there are screen 1 and screen 2, screen 1 is the virtual screen to be switched, and screen 2 is the target screen. If the content displayed on screen 1 before receiving the first switching operation is layer a, and the content displayed on screen 2 is layer b, then layer a is called the original content of screen 1, and layer b is called the synchronized content of screen 1. After screen 1 receives the first switching operation, the original content layer a of screen 1 is stored and does not change. At this time, the content displayed on screen 1 and screen 2 is both layer b. If a new layer c is generated on screen 2, the corresponding layer c is displayed on screen 1. If layer b of screen 2 changes, layer b displayed on screen 1 changes accordingly.

[0047] In a possible implementation, when the number of screens is two, the first switching operation includes a first switching instruction for one-key switching.

[0048] Among them, the first switching instruction of the first switching operation can be generated on the switching button displayed on the screen to be switched. The first switching instruction is an instruction that can be executed by the terminal. The generation method of the first switching instruction includes but is not limited to clicking the switching button or obtaining a voice instruction input by the user that matches the instruction preset by the terminal for activating the first switching instruction. The embodiment of the present application does not impose any limitation. The first switching instruction is used to make the screen to be switched display the content displayed on the target screen. For example, the two screens are screen 1 and screen 2. After the user clicks the switching button displayed on screen 1, the content displayed on screen 1 changes to the content displayed on screen 2.

[0049] In one possible implementation, when the number of screens is two, the virtual screen identifier of the virtual screen to be switched is changed according to the first switching instruction so that the virtual screen identifier of the virtual screen to be switched is consistent with the virtual screen identifier of the target virtual screen; and the layer carrying the target virtual screen identifier is distributed to the virtual screen to be switched.

[0050] According to the first switching instruction, the virtual screen identifier of the target virtual screen corresponding to the target screen is obtained, the virtual screen identifier of the virtual screen to be switched is changed to the virtual screen identifier of the target virtual screen, and according to the changed virtual screen identifier of the virtual screen to be switched, a layer carrying a virtual screen identifier consistent with the changed virtual screen identifier of the virtual screen to be switched is obtained, and the layer is distributed to the virtual screen to be switched, and the virtual screen to be switched maps the layer distributed to the virtual screen to be switched to the screen to be switched for display. For example, the two screens are screen 1 and screen 2, respectively. If the virtual screen identifier of virtual screen 1 corresponding to screen 1 is 1, and the virtual screen identifier of the virtual screen corresponding to screen 2 is 2, after the user clicks the switching button displayed on screen 1, the virtual screen identifier of virtual screen 1 is changed to 2, and the layer carrying the virtual screen identifier 2 is distributed to virtual screen 1, and virtual screen 1 maps the layer carrying the virtual screen identifier 2 to screen 1 for display.

[0051] In a possible implementation, when the number of screens is more than two, the first switching operation includes a first instruction for triggering switching and a second instruction for indicating a target screen to switch to.

[0052] Among them, the first instruction of the first switching operation can be generated on the selection button displayed on the screen to be switched, and the first instruction is an instruction that can be executed by the terminal. The generation method of the first instruction includes but is not limited to clicking the selection button or obtaining a voice instruction input by the user that matches the instruction preset by the terminal for activating the first instruction, and the embodiment of the present application does not make any restrictions. The first instruction is used to display a menu interface on the screen to be switched, and the content of the menu interface is the display content of each screen other than the screen to be switched, and the display content can be clicked; the second instruction of the first switching operation can be generated on the content of the menu interface, and the second instruction is an instruction that can be executed by the terminal. The generation method of the second instruction includes but is not limited to clicking the display content of a screen in the menu interface or obtaining a voice instruction input by the user that matches the instruction preset by the terminal for activating the second instruction, and the embodiment of the present application does not make any restrictions. The screen where the clicked display content is located is determined as the target screen, and the second instruction is used to make the screen to be switched display the content displayed on the target screen. For example, the terminal has three screens, namely screen 1, screen 2 and screen 3. After the user clicks the selection button displayed on screen 1, the content displayed on screen 2 and screen 3 is displayed on screen 1. The content of screen 2 and screen 3 displayed on screen 1 can be clicked. If the user clicks the display content of screen 2 displayed on screen 1, screen 1 changes from displaying the content displayed on screen 1 to displaying the content displayed on screen 2.

[0053] In one possible implementation, when the number of screens is more than two, screen information of each screen is obtained according to a first instruction and displayed on the virtual screen to be switched, and the screen information is used to distinguish the screens; the virtual screen identifier of the target virtual screen is obtained according to a second instruction; the virtual screen identifier of the virtual screen to be switched is changed according to the virtual screen identifier of the target virtual screen, so that the virtual screen identifier of the virtual screen to be switched is consistent with the virtual screen identifier of the target virtual screen; and the layer carrying the target virtual screen identifier is distributed to the virtual screen to be switched.

[0054] According to the first instruction, display contents of screens other than the screen to be switched are obtained and displayed on the screen to be switched; according to the second instruction, the target screen is determined, the virtual screen identifier of the target virtual screen corresponding to the target screen is obtained, the virtual screen identifier of the virtual screen to be switched is changed to the virtual screen identifier of the target virtual screen, and according to the changed virtual screen identifier of the virtual screen to be switched, a layer carrying a virtual screen identifier consistent with the changed virtual screen identifier of the virtual screen to be switched is obtained, and the layer is distributed to the virtual screen to be switched. The virtual screen to be switched maps the layer distributed to the virtual screen to be switched to the screen to be switched for display. For example, the terminal has three screens, namely screen 1, screen 2 and screen 3. If the virtual screen identifier of the virtual screen 1 corresponding to screen 1 is 1, the virtual screen identifier of the virtual screen corresponding to screen 2 is 2, and the virtual screen identifier of the virtual screen corresponding to screen 3 is 3, after the user clicks the selection button displayed on screen 1, the content displayed on screen 2 and screen 3 is displayed on screen 1, and the content of screen 2 and screen 3 displayed on screen 1 can be clicked. If the user clicks the display content of screen 2 displayed on screen 1, the virtual screen identifier 2 of the virtual screen 2 corresponding to screen 2 is obtained, the virtual screen identifier of virtual screen 1 is changed to 2, and the layer carrying the virtual screen identifier 2 is distributed to virtual screen 1, and virtual screen 1 maps the layer carrying the virtual screen identifier 2 to screen 1 for display.

[0055] It should be noted that, when the second instruction is not generated after the first instruction is generated or the first instruction is generated again, it means that the screen to be switched has not achieved synchronous display with other screens.

[0056] It should be noted that when the display contents of each screen other than the screen to be switched are obtained according to the first instruction and displayed on the screen to be switched, the display contents of each screen at the moment when the first instruction is generated are obtained. For example, screen 1 is the screen to be switched, the content displayed on screen 2 is layer a, and the original content of screen 3 is layer b, but before the first instruction is generated, screen 3 has been synchronized with screen 2, and the content displayed on screen 3 is layer a, and the content displayed on screen 4 is layer c. Then, according to the first instruction, the display content of screen 2 displayed on screen 1 is layer a, the display content of screen 3 is also layer a, and the display content of screen 4 is layer c. Then, when the target screen is screen 2 or screen 3, the content displayed on screen 1 after receiving the second instruction is layer a, and when the target screen is screen 4, the content displayed on screen 1 after receiving the second instruction is layer c.

[0057] By executing the above method, the original content of the screen can be retained, and the synchronous display of the screen can be achieved quickly and stably.

[0058] After the screen to be switched is displayed synchronously with the target screen, the content displayed on the screen to be switched can be switched back to the original content of the screen to be switched, thus realizing the switching between synchronous display and asynchronous display. Figure 2 , is a flow chart of another screen display method provided by an embodiment of the present application. Among them, steps S201-S202 and Figure 1 S101-S102 are the same and will not be described again here. After step S202, the following steps may also be included:

[0059] S203, changing the virtual screen identifier of the virtual screen to be switched according to the second switching operation of the user on the screen to be switched among the screens, and sending the active window carrying the virtual screen identifier to be switched to the virtual screen to be switched for display.

[0060] According to the second switching operation of the user on the screen to be switched, the virtual screen identifier of the virtual screen to be switched is changed, and the active window carrying the virtual screen identifier to be switched is sent to the virtual screen to be switched for display, and the second switching operation includes a third instruction for one-key switching; according to the third instruction, the default identifier of the virtual screen to be switched is obtained; according to the default identifier of the virtual screen to be switched, the virtual screen identifier of the virtual screen to be switched is changed, so that the virtual screen identifier of the virtual screen to be switched is consistent with the default identifier of the virtual screen to be switched; and the layer carrying the virtual screen identifier to be switched is distributed to the virtual screen to be switched.

[0061] It should be noted that when the number of screens is two, a switch button is displayed on each screen for switching to synchronous display or asynchronous display; when the number of screens is more than two, after the screen to be switched and the target screen are displayed synchronously, the selection button automatically becomes a switch button for quickly switching back to the original content of the screen to be switched, or there are both selection buttons and switch buttons on each screen, the selection button is used to select the screen to be displayed synchronously with it, and the switch button is used to quickly switch back to the original content of the screen to be switched, and when the screen to be switched displays the original content of the screen to be switched, clicking the switch button is equivalent to refreshing the display of the screen to be switched.

[0062] Among them, the third instruction of the second switching operation can be generated on the switch button displayed on the screen to be switched, and the third instruction is an instruction that can be executed by the terminal. The generation method of the third instruction includes but is not limited to clicking the switch button or obtaining a voice instruction input by the user that matches the instruction preset by the terminal for activating the third instruction, and the embodiment of the present application does not impose any limitation. The third instruction is used to make the screen to be switched display the original content of the screen to be switched. For example, the two screens are screen 1 and screen 2, and screen 1 synchronously displays the content displayed by screen 2. After the user clicks the switch button displayed on screen 1, screen 1 changes from displaying the content displayed on screen 2 to displaying the original content of screen 1.

[0063] The virtual screen identifier of the virtual screen to be switched is changed to the default identifier of the virtual screen to be switched, and a layer carrying a virtual screen identifier consistent with the changed virtual screen identifier of the virtual screen to be switched is obtained according to the changed virtual screen identifier of the virtual screen to be switched, and the layer is distributed to the virtual screen to be switched, and the virtual screen to be switched maps the layer distributed to the virtual screen to be switched to the screen to be switched for display. For example, the two screens are screen 1 and screen 2, the default identifier of screen 1 is 1, and the default identifier of screen 2 is 2. If screen 1 and screen 2 synchronously display the content of screen 2, the virtual screen identifiers of virtual screen 1 and virtual screen 2 corresponding to screen 1 and screen 2 are both 2. After the user clicks the switch button displayed on screen 1, the virtual screen identifier of virtual screen 1 is changed to 1, and the layer carrying the virtual screen identifier of 1 is distributed to virtual screen 1, and virtual screen 1 maps the layer carrying the virtual screen identifier of 1 to screen 1 for display.

[0064] By executing the above method, the original content of the screen can be obtained, and the asynchronous display of the screen can be achieved quickly and stably.

The layer carries the layer sequence number information, which is used to determine the order in which the active windows corresponding to the layer are displayed on the virtual screen.

[0074] Acquire the virtual screen identifier of the active window, so that the active window is displayed in a layered manner on each screen whose virtual screen identifier is consistent with the virtual screen identifier of the active window;
