Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The present application is mainly directed to audio and video synchronization processing of a display device having a dual-system and dual-display structure, that is, a display device having a first controller (first hardware system), a second controller (second hardware system), a first display and a second display, and the structure, function, implementation, and the like of the display device having the dual-system hardware structure will be described in detail below.

For convenience of use, various external device interfaces are usually provided on the display device, so as to connect different peripheral devices or cables to realize corresponding functions. When the high-definition camera is connected to the interface of the display device, if the hardware system of the display device does not have the hardware interface of the high-pixel camera for receiving the source code, the data received by the camera cannot be presented on the display screen of the display device.

Also, due to the hardware structure, the hardware system of the conventional display device only supports one path of hard decoding resource, and usually only supports video decoding with a resolution of 4K at maximum, so when video chat while watching the network television is to be implemented, in order not to reduce the definition of the network video picture, it is necessary to decode the network video using the hard decoding resource (typically, GPU in the hardware system), and in this case, only the video chat picture can be processed in such a way that the video is soft decoded by a general processor (e.g. CPU) in the hardware system.

The soft decoding is adopted to process the video chat pictures, so that the data processing load of the CPU is greatly increased, and when the data processing load of the CPU is too heavy, the problems of picture blocking or unsmooth can occur. Furthermore, due to the data processing capability of the CPU, when the video chat frame is processed by adopting the soft decoding of the CPU, the multi-channel video call cannot be realized, and when the user wants to perform video chat with a plurality of other users at the same time in the same chat scene, the situation of access blocking occurs.

Based on the above-mentioned aspects, to overcome the above-mentioned drawbacks, the present application discloses a dual hardware system architecture to implement multiple video chat data (at least one local video).

The concepts related to the present application will be described with reference to the accompanying drawings. It should be noted that the following descriptions of the concepts are only for making the content of the present application easier to understand, and do not represent a limitation on the protection scope of the present application.

In various embodiments of the present application, the hardware system may also be generally referred to as a motherboard (or a chip).

A schematic diagram of an operation scenario between a display device and a control apparatus according to an exemplary embodiment is exemplarily shown in fig. 1. As shown in fig. 1, a user may operate the display apparatus 200 by controlling the device 100.

The control device 100 may be a remote controller 100A, which may communicate with the display device 200 through infrared protocol communication, bluetooth protocol communication, zigBee protocol communication, or other short-range communication, and is used to control the display device 200 through wireless or other wired modes. The user may control the display device 200 by inputting user instructions through keys, voice input, control panel input, etc. on the remote controller 100A. Such as: the user can input corresponding control commands through volume up and down keys, channel control keys, up and down/right movement keys, voice input keys, menu keys, on/off keys, etc. on the remote controller 100A to realize the functions of the control display device 200.

The control apparatus 100 may also be an intelligent device, such as a mobile terminal 100B, a tablet computer, a notebook computer, etc., which may communicate with the display device 200 through a local network (LAN, local Area Network), a wide area network (WAN, wide Area Network), a wireless local area network (WLAN, wireless Local Area Network), or other networks, and control the display device 200 through an application program corresponding to the display device 200. For example, the display device 200 is controlled using an application running on a smart device. The application may provide various controls to the User through an intuitive User Interface (UI) on a screen associated with the smart device.

By way of example, both the mobile terminal 100B and the display device 200 may be provided with software applications, so that connection communication between the two may be implemented through a network communication protocol, thereby achieving the purpose of one-to-one control operation and data communication. Such as: the mobile terminal 100B and the display device 200 can be made to establish a control instruction protocol, the remote control keyboard is synchronized to the mobile terminal 100B, and the functions of controlling the display device 200 are realized by controlling the user interface on the mobile terminal 100B; the audio/video content displayed on the mobile terminal 100B may also be transmitted to the display device 200, so as to implement a synchronous display function.

As shown in fig. 1, the display device 200 may also be in data communication with the server 300 through a variety of communication means. In various embodiments of the present application, the display device 200 may be permitted to make a wired or wireless communication connection with the server 300 via a local area network, a wireless local area network, or other network. The server 300 may provide various contents and interactions to the display device 200.

By way of example, the display device 200 receives software program updates by sending and receiving information, and electronic program guide (EPG, electronic Program Guide) interactions, or accesses a remotely stored digital media library. The servers 300 may be one group, may be multiple groups, and may be one or more types of servers. Other web service content such as video on demand and advertising services are provided through the server 300.

The display device 200 includes a first display 201 and a second display 202, where the first display 201 and the second display 202 are independent from each other, and a dual hardware control system is adopted between the first display 201 and the second display 202.

Wherein the first display 201 and the second display 202 may be used to display different display screens. For example, the first display 201 may be used for screen display of a conventional television program, and the second display 202 may be used for screen display of auxiliary information such as notification messages, voice assistants, etc.

Alternatively, the content displayed on the first display 201 and the content displayed on the second display 202 may be independent from each other and not affect each other. For example, while the first display 201 plays a television program, the second display 202 may display information such as time, weather, air temperature, reminder messages, etc., that are not related to the television program.

Alternatively, there may be an association relationship between the content displayed on the first display 201 and the content displayed on the second display 202. For example, when the first display 201 plays the main screen of the video chat, the second display 202 may display information such as an avatar, a chat duration, and the like of the user currently accessing the video chat.

Alternatively, some or all of the content displayed by the second display 202 may be adjusted to the display of the first display 201. For example, information such as time, weather, air temperature, and a reminder message displayed on the first display 201 may be adjusted to be displayed on the first display 201, while other information is displayed on the second display 202.

In addition, the first display 201 displays the multi-party interactive screen while displaying the conventional television program screen, and the multi-party interactive screen does not obstruct the conventional television program screen. The display modes of the traditional television program picture and the multiparty interaction picture are not limited in the application. For example, the present application may set the positions and sizes of the conventional television program picture and the multiparty interactive picture according to the priorities of the conventional television program picture and the multiparty interactive picture.

Taking the example that the priority of the traditional television program picture is higher than that of the multiparty interaction picture, the area of the traditional television program picture is larger than that of the multiparty interaction picture, and the multiparty interaction picture can be positioned at one side of the traditional television program picture or suspended at one corner of the multiparty interaction picture.

The display device 200, in one aspect, may be a liquid crystal display, OLED (Organic Light Emitting Diode) display, projection display device; in another aspect, the display device may be a smart television or a display system of a display and a set-top box. The particular display device type, size, resolution, etc. are not limited, and those skilled in the art will appreciate that the display device 200 may be subject to some changes in performance and configuration as desired.

The display device 200 may additionally provide an intelligent network television function of a computer support function in addition to the broadcast receiving television function. Examples include web tv, smart tv, internet Protocol Tv (IPTV), etc. In some embodiments, the display device may not have broadcast receiving television functionality.

As shown in fig. 1, a camera may be connected or provided on the display device 200, so as to present a picture surface captured by the camera on a display interface of the present display device or other display devices, so as to implement interactive chat between users. Specifically, the picture shot by the camera can be displayed in a full screen, a half screen or any optional area on the display device.

As an optional connection mode, the camera is connected with the rear shell of the display device through the connection plate, and is fixedly installed in the middle of the upper side of the rear shell of the display device, and as an installable mode, the camera can be fixedly installed at any position of the rear shell of the display device, and the image acquisition area of the camera can be ensured not to be blocked by the rear shell, for example, the display orientation of the image acquisition area and the display device is the same.

As another alternative connection mode, the camera is connected with the rear shell of the display device in a liftable manner through a connection plate or other conceivable connectors, and a lifting motor is installed on the connector, so that when a user needs to use the camera or has an application program to use the camera, the camera is lifted out of the display device, and when the user does not need to use the camera, the camera can be embedded behind the rear shell, so that the camera is protected from being damaged and privacy security of the user is protected.

As an embodiment, the camera adopted in the application can be 1600 ten thousand pixels, so as to achieve the purpose of ultra-high definition display. In practical use, cameras higher or lower than 1600 ten thousand pixels may also be used.

After the camera is installed on the display device, the contents displayed in different application scenes of the display device can be fused in a plurality of different modes, so that the function which cannot be realized by the traditional display device is achieved.

For example, a user may conduct a video chat with at least one other user while watching a video program. The presentation of the video program may be a background picture over which a window of video chat is displayed. The function is visual and can be called as 'chat while watching'.

Optionally, in the scene of "watch while chat", at least one video chat is performed across terminals while live video or network video is being watched.

In another example, a user may conduct a video chat with at least one other user while entering the educational application study. For example, students may be able to achieve remote interaction with teachers while learning content in educational applications. The function is visual and can be called as 'learning while boring'.

In another example, a user may conduct a video chat with a player entering a game while playing a card game. For example, a player may enable remote interaction with other players when entering a gaming application to participate in a game. The function is visual and can be called 'play while watching'.

Optionally, the game scene is fused with the video picture, the portrait in the video picture is scratched, and the portrait is displayed in the game picture, so that the user experience is improved.

Optionally, in somatosensory games (such as ball playing, boxing, running, dancing, etc.), the body gestures and actions are obtained through the camera, limb detection and tracking, detection of key point data of the bones of the body, and then the body gestures and actions are fused with animation in the games, so that the games of scenes such as sports, dance, etc. are realized.

In another example, a user may interact with at least one other user in a karaoke application, video and voice. The function is visual and can be called 'watch and sing'. Optionally, when at least one user enters the application in the chat scene, a plurality of users can jointly complete recording of a song.

In another example, the user may open the camera locally to take pictures and video, and the function may be referred to as "looking at the mirror".

In other examples, more functions may be added or the above functions may be reduced. The function of the display device is not particularly limited in this application.

The application center may obtain these applications from different sources, store them in local storage, and then be run on the display device 200.

Since the second controller 310 and the first controller 210 may have separate operating systems installed therein, there are two independent but interrelated subsystems in the display device 200. For example, the second controller 310 and the first controller 210 may be independently provided with Android (Android) and various APP, which may each implement a certain function, and make the second controller 310 and the first controller 210 cooperatively implement a certain function.

A schematic diagram of a user interface in the display device 200 according to an exemplary embodiment is illustrated in fig. 9. As shown in fig. 9, the user interface includes a view first diagram display area 2011 and a second diagram display area 2021. The function implementation of the first drawing display area 2011 and the second drawing display area 2021 is substantially the same, and only the first drawing display area 2011 will be described with emphasis. By way of example, wherein the first view display area 2011 includes a layout of one or more different items. And a selector for indicating that the item is selected is also included in the user interface, and the position of the selector can be moved by user input to change the selection of a different item.

A "user interface" is a media interface for interaction and exchange of information between an application or operating system and a user, which enables conversion between an internal form of information and a user-acceptable form. A commonly used presentation form of a user interface is a Graphical User Interface (GUI), which refers to a user interface graphically displayed in connection with computer operations. It may be an interface element such as an icon, a window, a control, etc. displayed in a display screen of the electronic device, where the control may include a visual interface element such as an icon, a button, a menu, a tab, a text box, a dialog box, a status bar, a navigation bar, a Widget, etc.

In some embodiments, the first view display area 2011 is a scalable view display. "scalable" may mean that the first view display area 2011 is scalable in on-screen size or duty cycle, or that the items in the view display 201 are scalable in on-screen size or duty cycle.

"item" refers to a visual object displayed in a view display area of a user interface in the display device 200 to represent corresponding content such as an icon, a thumbnail, a video clip, and the like. For example: the items may represent movies, image content or video clips of a television show, audio content of music, applications, or other user access content history information.

Further, the item may represent an interface or an interface set display in which the display device 200 is connected to an external device, or may represent an external device name or the like connected to the display device. Such as: a set of signal source input interfaces, or a high definition multimedia interface (High Definition Multimedia Interface, HDMI), a USB interface, a PC terminal interface, or the like.

It should be noted that: the view display area may present Video chat project content or present application layer project content (e.g., web page Video, video On Demand (VOD) presentations, application screens, etc.).

"selector" is used to indicate that any item therein has been selected, such as: a cursor or a focus object. Positioning the selection information input according to the icon or menu position touched by the user in the display 200 may cause movement of the display focus object in the display device 200 to select a control item, one or more of which may be selected or controlled.

The focus object refers to an object that moves between items according to user input. Illustratively, the focus object location is achieved or identified by drawing a thick line through the item edge. In other embodiments, the focus form is not limited to examples, and may be a form in which a cursor or the like is tangible or intangible to a user, such as a form in which a 3D deformation of an item is possible, and may also change the mark of a border line, size, color, transparency, outline, and/or font of a text or image of the focused item.

The event transmission system 2914, which may monitor user input for each predefined event or sub-event, provides control identifying the event or sub-event directly or indirectly to the interface layout management module 2913.

The interface layout management module 2913 is configured to monitor a user interface state (including a position and/or a size of a view partition, an item, a focus, or a cursor object, a change process, etc.), and according to the event or the sub-event, modify a layout of a size and a position, a hierarchy, etc. of a view display area, and/or adjust or modify a size or a layout of a position, a number, a type, a content, etc. of a layout of various items in the view display area. In some embodiments, modifying and adjusting the layout includes displaying or not displaying item content in each view partition or view partition on the screen.

And a user input interface for transmitting an input signal of a user to the controller or transmitting a signal output from the controller to the user. Illustratively, the control device (e.g., mobile terminal or remote control) may send input signals such as power switch signals, channel selection signals, volume adjustment signals, etc., input by the user to the user input interface, which may then be forwarded to the controller; alternatively, the control device may receive an output signal such as audio, video, or data, which is output from the user input interface via the controller, and display the received output signal or output the received output signal in the form of audio or vibration.

In some embodiments, a user may input a user command through a Graphical User Interface (GUI) displayed on the display 200, and the user input interface receives the user input command through the Graphical User Interface (GUI). Alternatively, the user may input the user command by inputting a specific sound or gesture, and the user input interface recognizes the sound or gesture through the sensor to receive the user input command.

A block diagram of a display device presenting a dual system dual screen according to an exemplary embodiment is illustrated in fig. 10. Referring to fig. 10, the display device provided in the embodiment of the present invention includes two main controllers, which are a second controller and a first controller, respectively, where each main controller runs an independent Android system, that is, a system N (second hardware system) is configured in the second controller, a system a (first hardware system) is configured in the first controller, and the system N is a master system and the system a is a slave system.

To enable presentation of the capabilities of both systems to a user, the display device is configured with a dual display. The dual display comprises a first display (small screen) and a second display (large screen), wherein the second display is in communication connection with the system N and is used for displaying the display content of each application configured in the system N and providing main television service; the first display is connected with the camera and the system A and is used for displaying social capacity and auxiliary information prompt to a user. The system a has installed therein an application related to the camera, and the system N has installed thereon other applications for presenting social capabilities. The first display may also be connected to a system N, where the system N is configured to control on and off of a backlight of the first display when the first display is connected to the system N.

The system N and the system A are connected through HDMI interfaces, so that the switching of the interfaces of the system N and the system A can be realized. The two systems can be connected through a data path for realizing data transmission between the two systems. Because the system N does not provide social capability, functions such as video chat, magic mirrors and the like are configured on the system A, when a user performs video chat, the content of the system A is displayed through a second display (large screen) instead of a first display (small screen); and when the user exits the video chat, the content of the system A is displayed through the first display, and the second display displays the content of the system N.

Therefore, in order to realize the content coordination display in the large and small double screens of the double-system display device, the embodiment of the invention provides the double-screen display device, and when the application in the system A needs to be displayed on the second display, the application is switched to a data interface of the system A, and related data of the system A is transmitted to the second display for display; when the application in the system A no longer needs to be displayed on the second display, the data interface of the system N is switched to display the related data of the system N on the second display, and then the related data of the system A is displayed on the first display. Therefore, the dual-screen display device provided by the embodiment can realize coordinated display of dual-system application on the dual display.

A block diagram of a dual screen display device according to an exemplary embodiment is illustrated in fig. 11. Referring to fig. 11, a dual-screen display device provided in an embodiment of the present invention includes: the first controller, the second controller, the first display and the second display. The first display is in communication connection with the first controller and is configured to display content of a first application, wherein the first application is an application configured in the first controller; the second display is communicatively connected to the second controller, the second display being configured to display content of the first application or display content of a second application, the second application being an application configured in the second controller.

The first controller comprises an HDMI Switch module, the second controller comprises a signal source switching module, the first controller is configured to receive an application starting instruction sent by the second controller, and the HDMI Switch module switches a data interface; the signal source switching module is configured to switch the data interfaces of the first controller and the second controller, when the first application needs to be displayed on the second display, the signal source switching module can switch the currently connected data interface (the data interface of the second controller is connected under normal conditions) into the data interface of the first controller, so that the data interface of the first controller is connected with the second display, and the display content of the first application is displayed on the second display; and when the second application is displayed on the second display, the signal source switching module can switch the currently connected data interface (which can be the data interface of the first controller) into the data interface of the second controller, and establish the connection between the data interface of the second controller and the second display, so that the display content of the second application is displayed on the second display.

The triggering condition of the signal source switching module for switching the data interfaces of the two controllers is that the second controller receives the instruction, the second controller realizes the switching of the data interfaces, and the data interfaces are timely switched and connected with the corresponding display according to the display requirement of the application in each controller.

A flowchart of a method of switching a dual system size dual screen application display in accordance with an exemplary embodiment is illustrated in fig. 12. To this end, to enable coordinated presentation of dual system applications on a dual display, the second controller is configured to perform a method of switching dual system size dual screen application displays, see fig. 12, the method comprising:

s21, acquiring a connection state of a first controller data interface and a connection state of a second controller data interface, wherein the connection state of the data interfaces is used for representing whether the corresponding controller is connected with the first display or the second display currently.

When the coordinated display of the dual system application on the dual display is realized, the connection state of the dual display and the dual controller in the current dual-screen display device needs to be determined, and the connection state of the dual controller can be characterized by the signal source switching module. For this purpose, the second controller obtains the connection state of the signal source switching module, which is used to characterize the connection state of the first controller data interface and the connection state of the second controller data interface.

That is, according to the connection state of the signal source switching module, it can be determined whether the first controller data interface is connected to the first display or the second display, and whether the second controller data interface is connected to the second display. After determining the connection state of the first controller data interface and the connection state of the second controller data interface, it may be determined with which controller the second display is being connected, thereby determining whether a process of switching the data interfaces needs to be performed when a certain application is started later.

For example, the connection state of the signal source switching module may be determined, and may include, but is not limited to, a first controller data interface being connected to a first display, a second controller data interface being connected to a second display; the first controller data interface is connected with the second display, and the second controller data interface is not connected with any display and belongs to the undetermined state.

S22, receiving an application starting instruction for starting the appointed application, wherein the application starting instruction carries the packet name of the appointed application.

When a user starts a certain application through a homepage of the remote controller or the display device, the generated application starting instruction is sent to the second controller, and the second controller receives and responds to the application starting instruction to start the appointed application. The designated application may be an application configured in the first controller or an application configured in the second controller.

The homepage is configured in the first controller, and when a user wants to start an application in the first controller, the user needs to send an application start instruction to the second controller for processing whether the first controller or the second controller receives a request first.

When the user selects to start the appointed application, the sent application starting instruction comprises the packet name of the appointed application so as to distinguish the application.

S23, determining an application source and a display requirement of the specified application based on the package name of the specified application, wherein the application source is used for representing whether the specified application belongs to the first controller or the second controller, and the display requirement is used for representing whether display content of the specified application needs to be displayed on the first display or the second display.

The package name may determine the name of the specified application, and may also determine the source and the presentation requirement of the application, i.e. according to the package name, it may be determined that the specified application is an application that is configured in the first controller and that needs to be displayed on the first display, or that the specified application is an application that is configured in the first controller and that needs to be displayed on the second display, or that the specified application is an application that is configured in the second controller and that needs to be displayed on the second display.

S24, generating an interface switching identification based on the connection state of the first controller data interface, the connection state of the second controller data interface, the display requirement of the appointed application and the application source.

The connection status of the first controller data interface and the connection status of the second controller data interface may determine which controller is being connected to the second display and which controller is being connected to the first display, and the presentation requirements and application sources of a given application may explicitly determine whether the application is an application configured in the first controller or an application in the second controller, and whether the application needs to be displayed in the first display or in the second display. Therefore, according to the four parameters, whether the data interface of the corresponding controller needs to be switched can be judged, and when the data interface needs to be switched, an interface switching identifier is generated, and the interface switching identifier is used for realizing the calling of the data interface of the controller to which the specified application belongs.

In some embodiments, situations where it is desirable to generate an interface switch identification include, but are not limited to: when the data interface of the first controller is connected with the first display and the application is designated as the application which is required to be displayed in the second display, the switching is required at this time. When the data interface of the first controller is connected with the second display and the application is designated as the application which is required to be displayed in the first display, the switching is required at this time. When the data interface of the first controller is connected with the second display and the application is designated as the application which is required to be displayed in the second display, the switching is required at this time. The three cases in the above example are cases where the first controller data interface and the second controller data interface need to be switched, and at this time, an interface switching identifier needs to be generated to implement switching of the two controller data interfaces. It can be seen that the situation that the data interface needs to be switched is when the currently connected display of the same controller is inconsistent with the display to be connected by the display requirement, or when the currently connected display of the same controller is inconsistent with the controller to be connected.

In other embodiments, when the data interface of the first controller is currently connected to the second display and the application is designated as the application that needs to be displayed in the second display, the display content of the application in the first controller may be directly displayed in the second display without switching. When the data interface of the first controller is connected with the first display and the application is designated as the first controller and needs to be displayed in the first display, the display content of the application in the first controller can be directly displayed on the first display without switching. In this case, the display content of the application may be directly invoked to be displayed on the corresponding display.

S25, calling a data interface of the controller to which the specified application corresponding to the interface switching identification belongs, and displaying the display content of the specified application in a display corresponding to the display requirement.

When the data interfaces of the two controllers need to be switched, the second controller calls the data interface of the controller to which the appointed application belongs, the switched display and the data interface are determined in response to the interface switching identification, and the connection between the display and the data interface of the controller is established, so that the display content of the appointed application is displayed in the display, and the display is the target display determined according to the display requirement of the appointed application.

If the designated application is an application in the first controller and needs to be displayed on the second display, at this time, the first controller in the first controller needs to receive an application starting instruction sent by the second controller, and starts the designated application in response to the application starting instruction, and meanwhile, the data interface of the first controller is switched to the HDMI interface so as to transmit the display content of the designated application to the second display through the HDMI interface and display the display content.

In some exemplary embodiments of the present application, the second controller further comprises a signal source switching module configured to switch the data interface of the first controller with the second controller; and generating an interface switching identifier according to the following steps: acquiring a connection state of a signal source switching module, wherein the connection state of the signal source switching module is used for representing the connection state of a first controller data interface and the connection state of a second controller data interface; judging whether a current controller corresponding to the connection state of the signal source switching module is consistent with a controller to which the appointed application belongs or not and whether a current display corresponding to the connection state of the signal source switching module is consistent with a target display of the appointed application or not based on the connection state of the signal source switching module, the display requirement of the appointed application and the application source; and if the current controller corresponding to the connection state of the signal source switching module is consistent with the controller to which the appointed application belongs and the current display corresponding to the connection state of the signal source switching module is inconsistent with the target display of the appointed application, generating an interface switching identifier.

In some exemplary embodiments of the present application, the second controller is configured with a content presentation application therein; and presenting the display content of the specified application in the display corresponding to the display requirement, including: the method comprises the steps that a data interface of a first controller is connected with a first display, an application source of a specified application is the first controller, and when a display requirement is displayed on a second display, an application starting instruction carrying an interface switching identifier is sent to the first controller, and the first controller is used for switching the data interface of the first controller according to the interface switching identifier carried in the application starting instruction; starting a content display application, and generating a display interface in the second display, wherein the display interface of the content display application is used for displaying display content of a designated application; and calling the data interface after the switching of the first controller, and presenting the display content of the appointed application in the display interface corresponding to the second display.

In some exemplary embodiments of the present application, the data interface comprises an HDMI interface; and presenting the display content of the specified application in the display interface corresponding to the second display, including: invoking a signal source switching module to switch the signal source of the second controller to an HDMI (high-definition multimedia interface) of the first controller, wherein the HDMI is used for transmitting display contents of a specified application in the first controller; and receiving display content of the appointed application transmitted by the HDMI interface and displaying the display content in a display interface corresponding to the second display.

In some exemplary embodiments of the present application, the first display is communicatively coupled to the second controller; and, the method further comprises: receiving a first display backlight closing instruction sent by the first controller, wherein the first display backlight closing instruction is used for closing backlight of a first display in the first controller; and responding to the instruction for closing the backlight of the first display, and closing the backlight of the first display in the first controller.

In some exemplary embodiments of the present application, the method further comprises: acquiring display content of a previous application before display content of a specified application is displayed in the second display; the display content of the prior application is presented in a second display.

In some exemplary embodiments of the present application, the presenting the display content of the specified application in the display corresponding to the display requirement includes: the data interface of the first controller is connected with a second display, the application source of the appointed application is the second controller, and the display requirement is that the appointed application is started when the second display is displayed; calling a signal source switching module to switch the signal source of the second controller to a system interface of the second controller; and acquiring display content of the appointed application based on a system interface of the second controller, and presenting the display content in the second display.

In some exemplary embodiments of the present application, the method further comprises: transmitting an interface change notification to a first controller, wherein the interface change notification is used for enabling the first controller to acquire a homepage of the first controller and display the homepage in a first display, and transmitting a first display backlight starting instruction to a second controller; receiving a first display backlight starting instruction sent by the first controller, wherein the first display backlight starting instruction is used for starting backlight of a first display in the first controller; and responding to the instruction for starting the backlight of the first display, and starting the backlight of the first display in the first controller.

Another flowchart of a method of switching a dual system size dual screen application display in accordance with an exemplary embodiment is illustrated in fig. 13; a first dataflow diagram of a method of switching a dual system size dual screen application display according to an exemplary embodiment is illustrated in fig. 14. To this end, to enable coordinated presentation of dual system applications on a dual display, a first controller of a first controller is configured to perform a method of switching dual system size dual screen application displays, see fig. 13 and 14, the method comprising the steps of:

S11, receiving an application starting instruction which is sent by the second controller and carries an interface switching identifier, wherein the application starting instruction is used for starting a specified application, and the interface switching identifier is generated by the second controller based on the connection state of the data interface of the first controller, the connection state of the data interface of the second controller, the display requirement of the specified application and an application source.

After the user starts the designated application by sending an application start instruction to the second controller, the second controller executes the processes of steps S22 to S24, and generates an interface switching identifier according to the connection state of the first controller data interface and the connection state of the second controller data interface after determining the display requirement and the application source of the designated application. The first controller is required to perform a data interface switching specification designating the application as an application in the first controller and the application is required to be presented on the second display.

After the second controller generates the interface switching identifier, it is indicated that the display currently connected with the first controller is inconsistent with the display corresponding to the display requirement, and the data interface of the first controller needs to be switched to be connected with the display corresponding to the display requirement. For example, the data interface of the first controller is currently connected to the first display, and the designated application needs to be displayed on the second display, and the data interface of the first controller needs to be switched to HDMI to establish a connection with the second display, so that the display content of the designated application is output to the second display for display.

Therefore, when the second controller sends the application starting instruction to the first controller, the second controller needs to carry the interface switching identifier at the same time, so that the first controller can switch the data interface of the first controller according to the interface switching identifier after receiving the application starting instruction.

And S12, responding to an application starting instruction, switching a data interface, wherein the data interface is used for outputting display contents to the first display or outputting display contents to the second display.

And S13, starting a designated application based on the switched data interface, and displaying the display content of the designated application in a display calling the switched data interface.

The first controller responds to an application starting instruction to start a designated application, and meanwhile, the HDMI Switch module switches the display content output interface according to the interface switching identification, namely switches the data interface of the first controller to HDMI of the connection target display. After the first controller establishes connection between the interface switched by the first controller and the display calling the interface, the first controller can start the appointed application, and meanwhile, the display content of the appointed application is output to the display calling the interface for display. For example, the interface after the first controller is switched is called to be the second display, and then the display content of the appointed application is output to the second display for display.

In another embodiment, there is a case that the display content of the designated application needs to be displayed on the first display, and at this time, the first controller switches the data interface of the first controller to establish a connection with the first display, and calls the switched data interface as the first display. The first controller responds to the application starting instruction, starts the appointed application, and outputs display content of the appointed application to the first display for displaying.

It can be seen that, in the dual-screen display device provided by the embodiment of the present invention, when executing the switching method of dual-system dual-screen application display, the second controller receives an application start instruction triggered by a user, determines a display requirement and an application source of a specified application according to the application start instruction, and generates an interface switching identifier according to the connection state of the first controller data interface and the connection state of the second controller data interface. If the appointed application is an application in the first controller, the first controller receives and responds to an application starting instruction carrying an interface switching identifier sent by the second controller, after the data interface of the first controller is switched, the appointed application is started, and meanwhile, the display content of the appointed application is output to a display calling the switched data interface, which can be a first display or a second display, so that the coordinated display of the dual-system application on the dual display is realized.

In the foregoing step S24, several cases of switching the data interfaces are disclosed, including when the currently connected display of the same controller is inconsistent with the display to be connected by the display requirement, or when the currently connected controller of the same controller is inconsistent with the controller to be connected. The process of the second controller in generating the interface switch identifier is not the same for different situations.

A flowchart of a method of generating an interface switch identification in accordance with an exemplary embodiment is illustrated in fig. 15. Referring to fig. 15, the method is applicable to the case that the interface switching identifier is generated when the display connected currently of the same controller is inconsistent with the display to which the display requirement is to be connected. At this time, the second controller is further configured to perform the steps of:

s201, acquiring a connection state of a signal source switching module, wherein the connection state of the signal source switching module is used for representing the connection state of a first controller data interface and the connection state of a second controller data interface.

The signal source switching module configured in the second controller is used for switching the data connection gates of the first controller and the second controller, namely the signal source switching module is used for realizing the calling and switching of the data connection gates of the first controller and the data interfaces of the second controller. The second controller obtains the connection state of the signal source switching modules, and can determine which display the first controller data interface is connected with, or which display the second controller data interface is connected with.

For example, the first controller data interface is establishing a connection with the first display, or the first controller data interface is establishing a connection with the second display, or the second controller data interface is establishing a connection with the second display.

S202, judging whether a current controller corresponding to the connection state of the signal source switching module is consistent with a controller of the appointed application or not and whether a current display corresponding to the connection state of the signal source switching module is consistent with a target display of the appointed application or not based on the connection state of the signal source switching module, the display requirement of the appointed application and the application source;

s203, if the current controller corresponding to the connection state of the signal source switching module is consistent with the controller of the appointed application, and the current display corresponding to the connection state of the signal source switching module is inconsistent with the target display of the appointed application, generating an interface switching identifier.

The connection state of the signal source switching module can determine which display the data interfaces of the two controllers are in connection with, and the display requirement of the specified application can determine whether the application needs to display the first display or the second display, and the application source of the specified application can determine whether the application to be started is located in the first controller or the second controller. Therefore, the judgment criterion for judging whether or not a certain controller data interface needs to be switched is whether or not the controller connected with a certain display is consistent with the controller to which the specified application belongs, and whether or not the display connected with the current controller is consistent with the target display of the specified application. The target display is the display corresponding to the display requirement.

If the controller connected with a certain display is consistent with the controller of the appointed application and if the display connected with the current controller is inconsistent with the target display of the appointed application, the data interface needs to be switched so that the data interface of the controller of the appointed application is connected with the display corresponding to the display requirement.

For example, when the data interface of the first controller is currently connected to the first display, and the controller to which the designated application belongs is the first controller and the target display is the second display, a switch is required at this time. When the data interface of the current first controller is connected with the second display, and the assigned application belongs to the first controller and the target display is the first display, the switching is needed at this time.

And the second controller generates an interface switching identifier immediately when judging that the data interface switching is needed.

Another method flow diagram for generating an interface switch identification in accordance with an exemplary embodiment is illustrated in fig. 16. Referring to fig. 16, it is applicable to a case where the current controller connected to the same display and the controller to be connected are not identical. At this time, the second controller is further configured to perform the steps of:

S301, acquiring a connection state of a signal source switching module, wherein the connection state of the signal source switching module is used for representing the connection state of a first controller data interface and the connection state of a second controller data interface.

S302, based on the connection state of the signal source switching module, the display requirement of the appointed application and the application source, judging whether the current controller corresponding to the connection state of the signal source switching module is consistent with the controller of the appointed application, and whether the current display corresponding to the connection state of the signal source switching module is consistent with the target display of the appointed application.

S303, if the current controller corresponding to the connection state of the signal source switching module is inconsistent with the controller of the appointed application, and the current display corresponding to the connection state of the signal source switching module is consistent with the target display of the appointed application, generating an interface switching identifier.

In this embodiment, the contents of steps S301 to S302 refer to the contents of steps S201 to S202, and the criterion for determining whether the interface switching identifier needs to be generated by the second controller is the same as that of the previous embodiment, and will not be described again here.

If the second controller judges whether the controller connected with a certain display is inconsistent with the controller of the appointed application, and if the display connected with the current controller is consistent with the target display of the appointed application, the data interface is required to be switched, so that the data interface of the controller of the appointed application is connected with the display corresponding to the display requirement.

For example, when the data interface of the first controller is connected to the second display, and the controller to which the designated application belongs is the second controller and the target display is the second display, a switch is required at this time.

Therefore, according to the method for generating the interface switching identifier provided in the foregoing embodiments, the second controller may accurately determine whether to switch the data interface of the corresponding controller according to the relevant information (display requirement and application source) of the specified application and the connection state of the signal source switching module, and generate the interface switching identifier when the data is required to be switched.

And after the second controller judges that the data interface is required to be switched, calling the switched interface, and displaying the display content of the appointed application in the target display. In the above embodiment, but not limited to, three cases where the data interface needs to be switched are proposed, in order to display the display content of the specified application, that is, based on step S25, the following embodiment proposes three corresponding methods for displaying the display content of the specified application.

It should be noted that the case where the data interface needs to be switched is not limited to the three cases set forth in the foregoing embodiments, and the method of displaying the display content of the specified application is not limited to the three cases set forth in the following embodiments.

A first method flow diagram illustrating display content of a specified application in accordance with an exemplary embodiment is illustrated in fig. 17. Referring to fig. 14 and 17, in a case where the HDMI interface of the first controller is adapted to be output to the small screen but an application to be displayed on the large screen by the first controller is to be started, the second controller is further configured to perform the steps of:

s401, connecting a data interface of a first controller with a first display, designating an application source of an application as the first controller, and sending an application starting instruction carrying an interface switching identifier to the first controller when the second display is displaying the application source, wherein the first controller is used for switching the data interface of the first controller according to the interface switching identifier carried in the application starting instruction.

In the case that the data interface needs to be switched, for example, the display currently connected to the data interface of the first controller is the first display (small screen), but the designated application to be opened by the user is an application installed in the first controller, and when the application needs to be displayed on the second display (large screen), the second controller sends an application starting instruction to the first controller.

And the first controller switches the display content output interface to the HDMI connected with the second display by the HDMI Switch module according to the interface switching identification carried in the application starting instruction, namely, switches the data interface of the first controller to the HDMI interface, so that the output of the display content of the application is designated in the first controller.

S402, starting a content display application, and generating a display interface in a second display, wherein the display interface of the content display application is used for displaying display content of a specified application.

A content presentation application (LiveTV) is configured within the second controller and is initiated by the second controller. The content display application is used for providing a display interface after being started and is displayed in the second display, and the display content of the appointed application is displayed in the display interface.

The second controller immediately starts the content presentation application after sending the application start instruction to the first controller to generate a presentation interface in the second display.

S403, calling the data interface after the switching of the first controller, and displaying the display content of the appointed application in the display interface corresponding to the second display.

After the first controller switches the data interface of the first controller into the HDMI interface according to the interface switching identification carried in the application starting instruction, the second controller calls the HDMI interface of the first controller, and the display content of the appointed application is output to the second display through the HDMI interface and is presented in the display interface.

Specifically, when the second controller invokes the data interface after the first controller is switched to expose the display content of the specified application, the second controller is further configured to perform the following steps:

Step 501, a signal source switching module is invoked to switch the signal source of the second controller to the HDMI interface of the first controller, where the HDMI interface is used to transmit the display content of the specified application in the first controller.

When the data interface between the two controllers is switched, the switched data interface is an HDMI interface. And after the data interface of the first controller is switched to the HDMI interface, the first controller waits to be called.

The signal source (data interface) switching is realized in the dual-screen display device, so that the second controller controls the signal source switching module to switch the signal source of the second controller where the target display is located to the HDMI interface of the first controller, and the HDMI interface of the first controller is used for transmitting display contents of the appointed application.

In the process of switching the signal source by the signal source switching module, although the switching process is short, a blank can also appear in the second display. Thus, to avoid displaying the switch state in a flashing form on the second display, a default interface may be generated and displayed on the second display during the signal source switching process, obscuring the signal source callback process. And synchronously displaying the display interface of the second display and the display content of the appointed application after the signal source is switched.

Step 502, receiving display content of the designated application transmitted by the HDMI interface, and presenting the display content in a presentation interface corresponding to the second display.

After the signal source switching module completes switching of the signal source and establishes connection between the HDMI of the first controller and the second display, the second controller can receive display content of the designated application in the first controller transmitted through the HDMI. At this time, the second controller has opened the content presentation application and generated a presentation interface in the second display, and thus, the display content of the specified application can be presented in the presentation interface.

After the display content of the appointed application in the first controller is displayed in the second display, the first display does not need to provide social capability any more, and then can enter a standby state, and the backlight of the first display can be turned off. The backlight of the first display is controlled by a second controller of the second controllers, and therefore the first display is communicatively coupled to the second controller. At this time, in performing the turning off of the first display backlight, the second controller is further configured to perform the following method:

step 601, receiving a first display backlight closing instruction sent by a first controller, where the first display backlight closing instruction is used to close a backlight of a first display in the first controller.

Step 602, in response to a first display backlight closing instruction, closing a backlight of a first display in a first controller.

After the first controller completes the data interface switching of the first controller, the first display does not need to display relevant information of the designated application, so that the first controller can generate a command for turning off the backlight of the first display and send the command to the second controller. The second controller receives and responds to the instruction of turning off the backlight of the first display, and turns off the backlight of the first display.

In this embodiment, the second controller needs to call the signal source switching module to switch the signal source before the second controller executes the backlight closing instruction of the first display and before the process of displaying the display content of the designated application in the second display, the effect of turning off the backlight is presented, so that the influence on the visual effect of the user caused by the always on backlight of the first display in the process of switching the signal source and displaying the display content of the designated application is avoided, and the experience is poor.

For example, the user clicks the mirror application icon on the homepage, and after receiving an application start instruction for starting the application, the second controller determines that the mirror application in the first controller is started and needs to be displayed in the second display. At this time, the second controller generates an interface switching identifier and sends the interface switching identifier to the first controller along with an application starting instruction. The first controller sends a command for closing the backlight of the first display to the second controller, and the second controller closes the backlight of the first display after receiving the command. The second controller launches a content presentation application (LiveTV), generates a presentation interface and displays it in the second display. Meanwhile, the first controller switches the display content output interface to the HDMI connected with the second display by the HDMI Switch module according to the interface switching identification, namely, the data interface of the first controller is switched to the HDMI interface, so that the display content applied by the mirror is output to the HDMI connected with the second controller. The second controller calls the signal source switching module, and connection between the HDMI of the second controller and the HDMI of the first controller is established, so that display content of the mirror application is output to the second display through the HDMI and is displayed in the display interface. At this time, the second display (large screen) displays the interface of the mirror application, while the first display (small screen) is black.

A second method flow diagram illustrating display content of a specified application in accordance with an exemplary embodiment is illustrated in fig. 18; a second dataflow diagram of a method of switching a dual system size dual screen application display according to an exemplary embodiment is illustrated in fig. 19. Referring to fig. 18 and 19, in a case where the HDMI interface of the first controller is adapted to be output to the large screen but an application to be displayed on the small screen by the first controller is to be started, the first controller is further configured to perform the steps of:

and S701, connecting a data interface of the first controller with a second display, designating an application source of the application as the first controller, and receiving an application starting instruction carrying an interface switching identifier sent by the second controller when the display requirement is displayed by the first display so as to switch the data interface of the first controller according to the interface switching identifier carried in the application starting instruction.

In the case that the data interface needs to be switched, for example, the display currently connected to the data interface of the first controller is the second display (large screen), but the designated application to be opened by the user is the application installed in the first controller, and when the application needs to be displayed on the first display (small screen), the second controller sends an application starting instruction to the first controller.

And the first controller switches the display content output interface to the HDMI connected with the first display by the HDMI Switch module according to the interface switching identification carried in the application starting instruction, namely, the data interface of the first controller is switched to the HDMI interface, so that the display content of the specified application in the first controller is conveniently output to the small screen.

S702, calling a data interface after the switching of the first controller, and displaying the display content of the appointed application in a display interface corresponding to the first display.

After the first controller completes the switching of the first controller data interface, the first controller data interface disconnects from the second display and establishes a connection with the first display. And the first controller transmits the display content of the appointed application to the first display through the data interface switched by the first controller so as to be displayed on the first display.

The method provided by the embodiment is also suitable for the situation that when the application in the first controller runs, the display content of the application is displayed in the second display, and after the running of the application is finished, the display content of the application in the first controller is displayed in the first display again by switching the data interface. When the application in the first controller is realized and needs to be displayed on the large screen, the display content can be transmitted to the large screen; and when the display is not needed to be displayed on the large screen, the display content is transmitted to the small screen again by switching the data interface, so that the coordinated display of the double-screen application is realized.

Since the backlight of the first display is in an off state when the first display is not in use, the backlight of the first display needs to be turned on again after the first controller completes the data interface switching and displays the display content of the designated application. Specifically, in performing the turning on of the first display backlight, the first controller is further configured to:

step 801, sending a first display backlight starting instruction to a second controller, where the first display backlight starting instruction is used to start backlight of a first display in the first controller.

Step 802, the second controller starts the backlight of the first display in the first controller in response to the instruction for starting the backlight of the first display.

The first controller, after outputting the display content of the specified application to the first display, needs to turn on the backlight of the first display again in order to facilitate the user's viewing. Therefore, a first controller generates a first display backlight starting instruction and sends the first display backlight starting instruction to a second controller, and the second controller receives and responds to the first display backlight starting instruction to start the backlight of the first display, so that a user can conveniently view display content of a specified application displayed in the first display.

In this embodiment, after the first controller outputs the display content of the specified application to the first display after the timing of sending the instruction for starting the backlight of the first display, the first controller presents the effect of "back-on backlight", so as to avoid the situation that the first display is preferentially started, and the display content of the specified application is not displayed in the first display at this time, so that the blank display is prevented from being seen by the user.

After the display content of the appointed application in the first controller is switched from the second display to the first display for display, the second display does not need to display the display content of the appointed application any more, but a blank screen cannot be displayed, and at the moment, the second controller can acquire the previous display content for display. To this end, the second controller is further configured to perform the steps of:

step 901, acquiring display content of a previous application before displaying display content of a specified application in a second display.

Step 902, display content of a previous application is presented in a second display.

The second display executes a preset program of itself before displaying the display content of the specified application in the first controller, that is, the second display displays the display content of a certain application. The second display displays the display content of the previous application as the content that has been displayed before the display content of the specified application.

After the first controller switches the data interface, the connection with the second display is disconnected, and meanwhile, the second controller closes the content display application, and at the moment, the display interface is not displayed in the second display. In order to avoid blank screen of the second display, the second controller acquires the display content of the prior application and redisplays the display content of the prior application in the second display.

For example, when the user starts the application a, the second controller determines that the application a is an application in the first controller and needs to be displayed on the first display. And determining that the data interface of the first controller is connected with the second display according to the connection state of the signal source switching module, generating an interface switching identifier by the second controller at the moment, and sending the interface switching identifier to the first controller along with an application starting instruction through a data path. The first controller responds to the application starting instruction, and according to the interface switching identification, the HDMI Switch module switches the display content output interface to the HDMI connected with the first display, so that the data interface of the first controller is switched, the interface is connected with the first display, and the display content of the application A is output to the first display for display. At the same time, the second controller closes a content presentation application (LiveTV) and invokes the display content of the application before the second controller enters the LiveTV for presentation on the second display. The first controller sends a command for starting the backlight of the first display to the second controller, and the second controller starts the backlight of the first display after receiving the command. At this time, the second display (large screen) displays the display content of the previous application, and the first display (small screen) displays the display content of the application a.

A third method flowchart of presenting display content of a specified application in accordance with an exemplary embodiment is illustrated in fig. 20; a third data flow diagram of a method of switching a dual system size dual screen application display in accordance with an exemplary embodiment is illustrated in fig. 21. Referring to fig. 20 and 21, when the HDMI interface of the first controller is currently output to the large screen, but an application in the second controller needs to be started, the application in the second controller is displayed in the large screen, and the second controller is further configured to perform the following steps:

s1001, connecting a data interface of the first controller with a second display, designating an application source of the application as the second controller, and starting the designated application when the display requirement is displayed on the second display.

S1002, calling a signal source switching module to switch the signal source of the second controller to a system interface of the second controller.

S1003, acquiring display content of the designated application based on a system interface of the second controller, and presenting the display content in the second display.

In the case that the data interface needs to be switched, for example, the display currently connected to the data interface of the first controller is a second display (large screen), and the designated application to be opened by the user is an application installed in the second controller, and when the application needs to be displayed on the second display (large screen), the second controller sends an application starting instruction to the first controller.

In other embodiments, this may also occur when the display content of the application in the first controller provided in the above embodiments is displayed after the second display, and the user directly opens the application in the second controller.

The user triggers the designated application in the second controller, which then starts the designated application. At this time, in order to open the designated application, the second controller invokes the signal source switching module, and the data interface of the first controller, which is being connected to the second display, needs to be switched to the system interface of the second controller. Since the application is designated as an application in the second controller and the application can only be displayed in the second display, the signal source switching module switches to the system interface when switching back to the data interface in the second controller.

The second controller establishes connection between a system interface of the second controller and the second display, and outputs display content of the appointed application to the second display for display through the system interface.

Because the second display is displaying the display content of the application in the first controller, when the application in the second controller is forcedly started, the connection between the data interface of the first controller and the second display is cut off, and the display content of the application in the first controller can not be displayed in the second display. Thus, for subsequent processing of the application in the first controller, after the second controller starts the specified application, the second controller is further configured to perform the following method:

Step 1101, sending an interface change notification to the first controller, where the interface change notification is used to enable the first controller to acquire a homepage of the first controller, display the homepage in the first display, and send a command to turn on the backlight of the first display to the second controller.

Step 1102, receiving a first display backlight starting instruction sent by a first controller, where the first display backlight starting instruction is used for starting backlight of a first display in the first controller.

Step 1103, in response to the instruction for turning on the backlight of the first display, turning on the backlight of the first display in the first controller.

The second controller generates an interface change notification after switching to a system interface of the second controller and displaying display content of the appointed application in the second display, and sends the interface change notification to the first controller. The first controller receives and responds to the interface change notification to cut off the progress of the application originally displayed in the second display. Meanwhile, a homepage of the first controller is acquired, and the display content output interface is switched to the HDMI connected with the first display by the HDMI Switch module so as to display the homepage of the first controller in the first display. That is, after the application of the first controller is displayed in the second display and the user forcibly starts the application in the second controller, the application of the first controller that has been started is immediately terminated and the operation of the application is exited because the display content cannot be displayed in the first display.

After the first controller displays the homepage on the first display, the backlight of the first display needs to be turned on again in order to facilitate the user's viewing. Therefore, a first controller generates a first display backlight starting instruction and sends the first display backlight starting instruction to a second controller, and the second controller receives and responds to the first display backlight starting instruction to start the backlight of the first display, so that a user can conveniently view display content of a specified application displayed in the first display.

In this embodiment, the first controller obtains the content of the homepage from the first controller to the first display after sending the instruction for turning on the backlight of the first display, which shows the effect of "back-on backlight", so as to avoid the situation that the first display is turned on preferentially, but no content is displayed in the first display at this time, and avoid the blank display from being seen by the user.

For example, when the data interface of the first controller outputs to the second display, application B on the second controller is directly started (applications on system N are all displayed in the second display). When the user starts the application B, the second controller judges that the application B is the application on the second controller, the application B is started immediately, and the data interface output to the second display is switched to the system interface of the second controller. The second controller generates an interface switching notification and sends the interface switching notification to the first controller, after the first controller receives the interface switching notification, the first controller judges that the interface output to the second display is switched from HDMI to other signal sources (system interfaces), and then obtains the homepage of the first controller, and the HDMI Switch module switches the display content output interface to HDMI connected with the first display so as to display the homepage of the first controller on the first display. The first controller sends a command for starting the backlight of the first display to the second controller, and the second controller starts the backlight of the first display after receiving the command. At this time, the second display displays the display content of the application B, and the first display displays the homepage of the first controller.

According to the technical scheme, the dual-screen display device executes the switching method of the dual-system-size dual-screen application display, wherein the processing method of the second controller comprises the steps of obtaining the connection state of the data interface of the first controller and the connection state of the data interface of the second controller, receiving an application starting instruction carrying the package name for starting the appointed application, determining the application source and the display requirement of the appointed application based on the package name of the appointed application, and generating an interface switching identifier by combining the connection states of the data interfaces of the two controllers so as to realize the calling of the data interfaces of the corresponding controllers. And calling a data interface of the controller to which the specified application corresponding to the interface switching identification belongs, and displaying the display content of the specified application in a display corresponding to the display requirement. It can be seen that, in the dual-screen display device provided by the embodiment of the present invention, the second controller determines whether the designated application corresponding to the application start instruction belongs to the first controller or the second controller, and whether the display content of the designated application needs to be displayed on the first display or the second display, after determining the source and the display requirement of the application, generates the interface switching identifier to control the corresponding controller to switch the data interface, so as to realize the display of the display content of the designated application on the display corresponding to the display requirement, and ensure the coordinated display of the dual-system dual-screen application.
