Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The present application is not limited to a display device having a dual system and dual display structure as shown in fig. 1 to 7, 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 a display device having a non-dual system, that is, having one controller (hardware system), or having more than two controllers (hardware systems).

In a specific implementation manner of the present application, a display device with dual systems is used to describe the technical solution of the present application. The structure, function, implementation, and the like of the display device having the dual system hardware structure will be described in detail first.

For the convenience of users, various external device interfaces are usually provided on the display device to facilitate connection of different peripheral devices or cables to implement corresponding functions. When a high-definition camera is connected to an interface of the display device, if a hardware system of the display device does not have a hardware interface of a high-pixel camera receiving the source code, data received by the camera cannot be displayed on a display screen of the display device.

Furthermore, due to the hardware structure, the hardware system of the conventional display device only supports one path of hard decoding resources, and usually only supports video decoding with a resolution of 4K at most, so when a user wants to perform video chat while watching a network television, the user needs to use the hard decoding resources (usually GPU in the hardware system) to decode the network video without reducing the definition of the network video screen, and in this case, the user can only process the video chat screen by using a general-purpose processor (e.g. CPU) in the hardware system to perform soft decoding on the video.

The soft decoding is adopted to process the video chat picture, so that the data processing burden of a CPU (central processing unit) can be greatly increased, and when the data processing burden of the CPU is too heavy, the problem of picture blocking or unsmooth flow can occur. Further, due to the data processing capability of the CPU, when the CPU performs soft decoding on the video chat screen, multi-channel video calls cannot be generally implemented, and when a user wants to perform video chat with multiple other users in the same chat scene, access is blocked.

In view of the above aspects, to overcome the above drawbacks, the present application discloses a dual hardware system architecture to implement multiple channels of video chat data (at least one channel of local video).

The concept to which the present application relates will be first explained below with reference to the drawings. It should be noted that the following descriptions of the concepts are only for the purpose of facilitating understanding of the contents of the present application, and do not represent limitations on the scope of the present application.

The term "module," as used in various embodiments of the present application, may refer to any known or later developed hardware, software, firmware, artificial intelligence, fuzzy logic, or combination of hardware and/or software code that is capable of performing the functionality associated with that element.

The term "remote control" as used in the embodiments of the present application refers to a component of an electronic device (such as the display device disclosed in the present application) that is capable of wirelessly controlling the electronic device, typically over a short distance. The component may typically be connected to the electronic device using infrared and/or Radio Frequency (RF) signals and/or bluetooth, and may also include functional modules such as WiFi, wireless USB, bluetooth, motion sensors, etc. For example: the hand-held touch remote controller replaces most of the physical built-in hard keys in the common remote control device with the user interface in the touch screen.

The term "gesture" as used in the embodiments of the present application refers to a user behavior used to express an intended idea, action, purpose, or result through a change in hand shape or an action such as hand movement.

The term "hardware system" used in the embodiments of the present application may refer to a physical component having computing, controlling, storing, inputting and outputting functions, which is formed by a mechanical, optical, electrical and magnetic device such as an Integrated Circuit (IC), a Printed Circuit Board (PCB) and the like. In various embodiments of the present application, a hardware system may also be referred to as a motherboard (or chip).

Fig. 1 is a schematic diagram illustrating an operation scenario between a display device and a control apparatus. As shown in fig. 1, a user may operate the display apparatus 200 through the control device 100.

The control device 100 may be a remote controller 100A, which can communicate with the display device 200 through an infrared protocol communication, a bluetooth protocol communication, a ZigBee (ZigBee) protocol communication, or other short-range communication, and is used to control the display device 200 in a wireless or other wired manner. The user may input a user instruction through a key on the remote controller 100A, voice input, control panel input, or the like to control the display apparatus 200. Such as: the user can input a corresponding control command through a volume up/down key, a channel control key, up/down/left/right movement keys, a voice input key, a menu key, a power on/off key, etc. on the remote controller 100A to control the functions of the display device 200.

The control device 100 may also be an intelligent device, such as a mobile terminal 100B, a tablet computer, a notebook computer, and the like, which may communicate with the display device 200 through a Local Area Network (LAN), a Wide Area Network (WAN), a Wireless Local Area Network (WLAN), or other networks, and implement control of 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 program running on the 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.

For example, the mobile terminal 100B and the display device 200 may each have a software application installed thereon, so that connection communication between the two can be realized through a network communication protocol, and the purpose of one-to-one control operation and data communication can be further realized. Such as: a control instruction protocol can be established between the mobile terminal 100B and the display device 200, a remote control keyboard is synchronized to the mobile terminal 100B, and the function of controlling the display device 200 is realized by controlling a user interface on the mobile terminal 100B; the audio and 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 apparatus 200 may also perform data communication with the server 300 through various communication means. In various embodiments of the present application, the display device 200 may be allowed to be in 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 apparatus 200.

Illustratively, the display device 200 receives software Program updates, or accesses a remotely stored digital media library by sending and receiving information, and Electronic Program Guide (EPG) interactions. The servers 300 may be a group or groups, and may be one or more types of servers. Other web service contents such as a video on demand and an advertisement service are provided through the server 300.

The display device 200 includes a first display 201 and a second display 202, wherein the first display 201 and the second display 202 are independent from each other, and the first display 201 and the second display 202 are controlled by different hardware systems respectively.

The first display 201 and the second display 202 may be used to display different screen contents. For example, the first display 201 may be used for screen display of conventional television programs, and the second display 202 may be used for screen display of auxiliary information such as notification type messages, voice assistants, and the like.

Alternatively, the content displayed by the first display 201 and the content displayed by the second display 202 may be independent of each other and not affected by each other. For example, when the first display 201 plays a television program, the second display 202 may display information such as time, weather, temperature, reminder messages, and the like, which are not related to the television program.

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

Optionally, part or all of the content displayed by the second display 202 may be adjusted to be displayed by the first display 201. For example, the information such as time, weather, temperature, reminder message, etc. 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 picture while displaying the traditional television program picture, and the multi-party interactive picture does not block the traditional television program picture. The display mode of the traditional television program picture and the multi-party interactive picture is not limited by the application. For example, the position and the size of the traditional television program picture and the multi-party interactive picture can be set according to the priority of the traditional television program picture and the multi-party interactive picture.

Taking the example that the priority of the traditional television program picture is higher than that of the multi-party interactive picture, the area of the traditional television program picture is larger than that of the multi-party interactive picture, and the multi-party interactive picture can be positioned at one side of the traditional television program picture and can also be arranged at one corner of the multi-party interactive picture in a floating manner.

The display device 200, in one aspect, may be a liquid crystal display, an oled (organic Light Emitting diode) display, a projection display device; in another aspect, the display system may be a smart television or a display and a set-top box. The specific type, size, resolution, etc. of the display device 200 are not limited, and those skilled in the art will appreciate that the display device 200 may vary somewhat in its capabilities and configuration as desired.

The display apparatus 200 may additionally provide an intelligent network tv function that provides a computer support function in addition to the broadcast receiving tv function. Such as a network television, a smart television, an Internet Protocol Television (IPTV), etc. In some embodiments, the display device may not have a broadcast receiving television function.

As shown in fig. 1, a camera may be connected or disposed on the display device 200, and is used to present a picture taken by the camera on a display screen of the display device or other display devices, so as to implement interactive chat between users. Specifically, the picture shot by the camera may be displayed on the display device in a full screen, a half screen, or in any selectable area.

As an optional connection mode, the camera is connected with the rear shell of the display device through the connecting plate, and is fixedly installed in the middle of the upper side of the rear shell of the display device.

As another optional connection mode, the camera is connected to the rear shell of the display device through a connection board or another conceivable connector, the camera is capable of lifting and descending, a lifting motor is installed on the connector, when a user wants to use the camera or an application program wants to use the camera, the camera is lifted out of the display device, and when the camera is not needed, the camera can be embedded into the rear shell, so that the camera is protected from being damaged, and privacy safety of the user is protected.

As an embodiment, the camera adopted in the present application may have 1600 ten thousand pixels, so as to achieve the purpose of ultra high definition display. In actual 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 by different application scenes of the display device can be fused in various different modes, so that the function which cannot be realized by the traditional display device is achieved.

Illustratively, 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 as a background frame over which a window for video chat is displayed. The function is called 'chat while watching'.

Optionally, in a scene of "chat while watching", at least one video chat is performed across terminals while watching a live video or a network video.

In another example, a user can conduct a video chat with at least one other user while entering the educational application for learning. For example, a student may interact remotely with a teacher while learning content in an educational application. Vividly, this function can be called "chatting while learning".

In another example, a user conducts a video chat with a player entering a card game while playing the game. For example, a player may enable remote interaction with other players when entering a gaming application to participate in a game. Figuratively, this function may be referred to as "watch while playing".

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

Optionally, in the motion sensing game (such as ball hitting, boxing, running and dancing), the human posture and motion, limb detection and tracking and human skeleton key point data detection are obtained through the camera, and then the human posture and motion, the limb detection and tracking and the human skeleton key point data detection are fused with the animation in the game, so that the game of scenes such as sports and dancing is realized.

In another example, a user may interact with at least one other user in a karaoke application in video and voice. Vividly, this function can be called "sing while watching". Optionally, when at least one user enters the application in a chat scenario, multiple users may jointly complete recording of a song.

In another example, a user may turn on a camera locally to take pictures and videos, figurative, which may be referred to as "looking into the mirror".

In other examples, more or less functionality may be added. The function of the display device is not particularly limited in the present application.

The event transmission system 2914 may be implemented within the operating system 2911 or within the application 2912. In some embodiments, an aspect is implemented within the operating system 2911 and concurrently in the application programs 2912 for listening for various user input events, and will implement one or more sets of predefined operations in response to various events referring to the recognition of various types of events or sub-events.

The event monitoring module 2914-1 is configured to monitor an event or a sub-event input by the user input interface.

The event identification module 2914-2 is used to input various event definitions for various user input interfaces, identify various events or sub-events, and transmit them to the process for executing one or more sets of their corresponding handlers.

The event or sub-event refers to an input detected by one or more sensors in the display device 200 and an input of an external control device (e.g., the control apparatus 100). Such as: the method comprises the following steps of inputting various sub-events through voice, inputting a gesture sub-event through gesture recognition, inputting a remote control key command of a control device and the like. Illustratively, the one or more sub-events in the remote control include a variety of forms including, but not limited to, one or a combination of key presses up/down/left/right/, ok keys, key presses, and the like. And non-physical key operations such as move, hold, release, etc.

The interface layout management module 2913, directly or indirectly receiving the input events or sub-events from the event transmission system 2914, monitors the input events or sub-events, and updates the layout of the user interface, including but not limited to the position of each control or sub-control in the interface, and the size, position, and level of the container, which are related to the layout of the interface.

Since the operating system 3911 of the second controller 310 is similar to the operating system 2911 of the first controller 210 in function, reference may be made to the operating system 2911 for details, which are not repeated herein.

As shown in fig. 8, the application layer of the display device includes various applications that can be executed at the display device 200.

The application layer 2912 of the first controller 210 may include, but is not limited to, one or more applications such as: a video-on-demand application, an application center, a game application, and the like. The application layer 3912 of the second controller 310 may include, but is not limited to, one or more applications such as: live television applications, media center applications, and the like. It should be noted that what applications are respectively contained in the second controller 310 and the first controller 210 is determined according to the operating system and other designs, and the present invention does not need to make specific limitations and divisions on the applications contained in the second controller 310 and the first controller 210.

The live television application program can provide live television through different signal sources. For example, a live television application may provide television signals using input from cable television, radio broadcasts, satellite services, or other types of live television services. And, the live television application may display video of the live television signal on the display device 200.

A video-on-demand application may provide video from different storage sources. Unlike live television applications, video on demand provides a video display from some storage source. For example, the video on demand may come from a server side of the cloud storage, from a local hard disk storage containing stored video programs.

The media center application program can provide various applications for playing multimedia contents. For example, a media center, which may be other than live television or video on demand, may provide services that a user may access to various images or audio through a media center application.

The application program center can provide and store various application programs. The application may be a game, an application, or some other application associated with a computer system or other device that may be run on a display device. The application center may obtain these applications from different sources, store them in local storage, and then be operable on the display device 200.

Since the second controller 310 and the first controller 210 may have independent operating systems installed therein, there are two independent but interrelated subsystems in the display apparatus 200. For example, Android (Android) and various APPs may be independently installed on the second controller 310 and the first controller 210, and may all realize a certain function, and the second controller 310 and the first controller 210 cooperate to realize a certain function.

Fig. 9 illustrates a schematic diagram of a user interface in the display device 200. As shown in fig. 9, the user interface includes a first view display area 2011 and a second view display area 2021. The first view display area 2011 and the second view display area 2021 have substantially the same function, and only the first view display area 2011 is described in an important manner below. Illustratively, among other things, the first view display 2011 includes layouts for one or more different items. And a selector indicating that the item is selected is also included in the user interface, and a position of the selector is movable by a user input to change a selection of a different item.

A "user interface" is a media interface for interaction and information exchange between an application or operating system and a user that enables the conversion of the internal form of information to a form acceptable to the user. A common presentation form of a user interface is a Graphical User Interface (GUI), which refers to a user interface related to computer operations and displayed in a graphical manner. It may be an interface element such as an icon, a window, a control, etc. displayed in the 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 size or proportion on the screen, and the items in the first view display area 2011 are scalable in size or proportion on the screen.

The "item" is displayed in a view display area of the user interface in the display device 200 to represent a visual object of 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 a collection of interfaces on which the display device 200 is connected to an external device, or may represent a name of an external device connected to the display device, or the like. Such as: a signal source input Interface set, or a High Definition Multimedia Interface (HDMI), a USB Interface, a PC terminal Interface, and the like.

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

A "selector" is used to indicate where any item has been selected, such as a cursor or a focus object. Positioning the selection information input according to an icon or menu position touched by the user in the display 200 may cause movement of a focus object displayed 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 position is implemented or identified by drawing a thick line through the item edge. In other embodiments, the focus form is not limited to an example, and may be a form such as a cursor that is recognizable by the user, either tangible or intangible, such as in the form of a 3D deformation of the item, or may change the identification of the border lines, size, color, transparency, and outline and/or font of the text or image of the item in focus.

The event transmission system 2914, which may monitor user input for each predefined event or sub-event heard, 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 the state of the user interface (including the position and/or size of the view partition, the item, the focus or the cursor object, the change process, and the like), and according to the event or the sub-event, may perform a modification on the layout of the size and position, the hierarchy, and the like of the view display area, and/or adjust or modify the layout of the size or/and position, the number, the type, the content, and the like of the layout of various items in the view display area. In some embodiments, the layout is modified and adjusted, including displaying or not displaying the view sections or the content of the items in the view sections 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. For example, the control device (e.g., a mobile terminal or a remote controller) may send an input signal, such as a power switch signal, a channel selection signal, a volume adjustment signal, etc., input by a user to the user input interface, and then the input signal is forwarded to the controller by the user input interface; alternatively, the control device may receive an output signal such as audio, video, or data output from the user input interface via the controller, and display the received output signal or output the received output signal in audio or vibration form.

In some embodiments, a user may input a user command on 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 receives the user input command by recognizing the sound or gesture through the sensor.

Referring again to the hardware architecture block diagram of the display device shown in fig. 5, the display device provided in the embodiment of the present invention includes two controllers, which are a second controller and a first controller, respectively, each controller runs an independent Android system, that is, a system N runs on the second controller, a system a runs on the first controller, the system N is a master system, and the system a is a slave system.

To enable the capabilities of both systems to be exposed to the user, the display device is configured with dual displays. The dual display includes a first display (small screen) 280 configured to display contents of a first application as a sub-screen, the first application being an application configured in the first controller, and a second display (large screen) 380; the second display is configured to display, as a home screen, display content of a first application or display content of a second application, which is an application configured in the second controller.

The second display 380 (i.e. the first display 201 in fig. 1) is communicatively connected to the second controller 310 (system N) for displaying the display content of each application configured in the system N and providing the main tv service; the first display 280 (i.e., the second display 202 in fig. 1) is connected to the camera and the first controller 210 (system a) for displaying the social ability and the auxiliary information prompt to the user. The system A is provided with an application related to the camera, and the system N is provided with other applications for presenting social ability. The first display may also be connected to the system N, and the system N is configured to control the backlight of the first display to be turned on and off when the first display is connected to the system N.

The system N and the system A are connected through a USB interface, a serial port or an HDMI interface, and the switching of the system N and the system A interface can be realized. The two systems can be connected through a data path to realize data transmission between the two systems. Because the system N does not provide social ability, the functions of video chat, magic mirror and the like are configured on the system A, and when a user conducts video chat, the content of the system A is displayed through the second display (large screen) instead of the first display (small screen).

When the user quits the video chat, the display device provided by the embodiment can coordinate and control the two systems, so that the corresponding application content can be accurately displayed on the large screen and the small screen. For example, if the first display previously displayed the home page of system a, the second display previously displayed a video playback, such as a video played by a media center. At this point, the user triggers the display of the first application to be presented on the second display, for example, launching and displaying a "mirror" application in the first controller on the second display. In this scenario, after the user triggers the return key on the remote control, the second display ends displaying the content of the "look at mirror" application, and displays the application before starting the "look at mirror" application, i.e., the homepage of system a, in the first display; the video playback that was displayed prior to the "mirror" application, i.e., the video played by the media center, is displayed in the second display.

For another example: when a user conducts video chat on one display, a video chat interface is displayed on a second display (a main screen). If the user wants to watch other video programs with the chatting person, the display device is required to transfer the video chat content to another display (usually a small-sized sub-screen) of the same product. The effect of continuing to carry out video chat on the other display when the original display watches other video programs is achieved.

It can be seen that, in the process of starting the application in the first controller and needing to be displayed on the second display, or when the content displayed on the first display is switched to the second display for display, there is a scene that is switched from the small screen to the large screen; and in the process after the first application displayed in the second display is quitted, or when the display content displayed on the second display is switched back to the first display for display, a scene of switching from a large screen to a small screen exists. When the two displays switch the display screen, the processing schedules of the two controllers cannot be kept consistent, so that the two displays cannot synchronously display the screen.

Therefore, when the dual-screen display device switches the displays, the phenomenon that the two displays flicker or blue screen and the like due to the fact that the two displays cannot synchronously display corresponding pictures is avoided, and the user impression is influenced. The display device provided by the embodiment of the invention can add animation effect to the two displays for shielding in the process of switching the double screens, thereby avoiding the phenomena of screen flashing, blue screen and the like of the two displays from being seen by a user when the pictures are switched. The animation effect can be quickly transmitted across the system and played simultaneously, and the effects of quick switching and smooth animation are achieved.

A first flowchart of a method for displaying a two-screen two-system screen-switching animation according to an exemplary embodiment is illustrated in fig. 10. Referring to fig. 10, in a display device according to an embodiment of the present invention, when performing display of a dual-screen dual-system screen switching animation, specifically when adding an animation effect during switching from a large screen to a small screen, a second controller is configured to perform the following steps:

and S11, capturing the appointed picture displayed in the second display to obtain the appointed picture.

The display device provided by the embodiment is characterized in that when the content displayed in the second display is switched to the first display for display, the animation effect added in the switching process comes from the display picture of the current display, namely the display picture in the second display.

The second controller intercepts the current displayed picture of the second display as a designated picture and stores the designated picture as an animation effect for shielding.

And S12, dividing the designated picture into a plurality of picture blocks to form a picture block set, and displaying the picture block set in the second display.

Since the communication speed across the system is slow, the designated picture data amount intercepted by the second controller is large, for example, 1920 × 1080 pixels, four bytes of color data per pixel ARGB _8888, totaling 7.9 MB. If the second controller directly sends the picture with larger data volume to the first controller, the first controller will need a period of time to receive the specified picture, and the whole picture as the animation material is loaded, so that the time is consumed, and the effect of quickly generating transition animation when the content of the double-display is switched cannot be achieved.

A schematic diagram of a second display displaying a set of picture blocks according to an exemplary embodiment is illustrated in fig. 11. Therefore, referring to fig. 11, the display device provided in this embodiment may cut the cut specified picture by the second controller to obtain a plurality of sub-blocks, i.e. a plurality of picture blocks, and reference numerals 1 to 15 in fig. 11 exemplarily show a schematic diagram of dividing the specified picture into 15 picture blocks. The 15 picture blocks form a picture block set and are displayed in the second display so as to shield the second display in the process of picture switching. At this time, the complete picture block set displayed in the second display is the initial state of the animation effect.

In order to ensure that the animation effect is presented when the large screen is switched to the small screen, the second controller can divide the designated pictures according to the manner of presenting the animation effect. In particular, in forming the set of picture blocks for rendering the animation effect, the second controller is further configured to:

and step 121, acquiring a preset animation sliding direction.

And step 122, equally cutting the appointed picture into a plurality of picture blocks along the direction parallel to the sliding direction of the preset animation to form a picture block set.

The preset animation sliding direction is used for representing the switching direction when the screen displays the animation. As shown in fig. 11, since the two displays are in a top-bottom structure, and the second display is located above the first display, when the second display switches pictures to the first display, the sliding direction of the animation is preset from top to bottom, that is, the designated picture is gradually displayed in the first display from the first picture block on the left side in a downward falling manner, so that the effect of switching the animation from the second display to the first display is achieved.

In order to enable the designated pictures to be sequentially sent to the first controller according to a certain sequence and be sequentially displayed in the first display according to the certain sequence, the second controller determines that the cutting direction can be parallel or perpendicular to the sliding direction of the preset animation when the designated pictures are cut. Fig. 11 is a diagram showing the effect when the cutting direction is parallel to the preset animation slip.

In addition, in order to ensure that the time consumed by the first controller for receiving and loading each picture block is the same, and avoid the phenomenon that one part of the animation effect is displayed quickly and the other part of the animation effect is displayed slowly, in the embodiment, the second controller can equally cut the appointed pictures, so that the presentation of the animation effect is smoother and smoother. That is, each tile is the same in size and shape and is arranged in an order perpendicular to the sliding direction of the preset animation, i.e., from left to right.

In other embodiments, the designated picture may not be cut according to the equal requirement, and the cutting direction may not be parallel to the sliding direction of the preset animation, for example, perpendicular or at an angle. If the designated picture is randomly cut, the size and the shape of each formed picture block are different, and the arrangement sequence may not be in the sequence of the preset animation sliding direction. For example, if the cutting direction is perpendicular to the sliding direction of the preset animation, the arrangement sequence of the picture blocks is from top to bottom; when sending to the first controller, the second controller may send the picture blocks located at the lowest layer of the second display first, that is, sequentially send the picture blocks to the first controller from bottom to top.

If the designated picture is cut randomly, the arrangement sequence of each picture block is irrelevant to the preset animation sliding direction, at the moment, when the animation effect is presented, the second controller can mark each picture block and send the corresponding picture block to the first controller according to the mark sequence.

And S13, sequentially sending each picture block to the first controller according to a preset animation sliding direction, so that the first controller displays each picture block received sequentially in the first display, and the preset animation sliding direction is used for representing the switching direction when the screen displays the animation.

After finishing the designated picture cutting, the second controller respectively sends each picture block to the first controller through the USB port, the Ethernet or other interfaces in sequence according to the preset animation sliding direction, so that each time the first controller receives one picture block, the picture block is displayed in the first display, and the animation effect that the picture moves slowly from the second display to the first display is presented.

An animation effect diagram in which a tile is first moved from top to bottom according to an exemplary embodiment is illustrated in fig. 12. Referring to fig. 12, when an animation effect of a slow movement of a picture, that is, an effect of a movement from top to bottom, is presented, the second controller may sequentially send the picture blocks to the first controller according to a certain sequence.

In this embodiment, when sequentially transmitting each picture block, the second controller is further configured to:

and 131, acquiring the picture blocks which are centrally positioned at the front end according to the preset animation sending direction.

Step 132, the picture block at the front end is sent to the first controller.

If the preset animation sending direction is from left to right, the picture block at the front end in the picture block set is the leftmost picture block, namely the picture block corresponding to the sequence number 1. When the second controller determines the picture block which is in accordance with the preset animation sending direction and is positioned at the front end, namely the picture block with the sequence number of 1 is determined, the second controller sends the picture block to the first controller.

S14, receiving a corresponding tile receiving instruction sent by the first controller when the tile receiving is completed.

When the first controller receives the current picture block sent by the second controller, in order to ensure the animation effect and present the effect that the picture is moving slowly, the picture block which is moved to the first controller in the second display needs to be eliminated in the second display. Therefore, in order to enable the second controller to immediately eliminate the picture blocks displayed in the second display and sent to the first controller, the first controller generates a picture block receiving instruction immediately after receiving the picture blocks and feeds the picture block receiving instruction back to the second controller.

S15, deleting the tile corresponding to the tile receiving instruction in the tile set, and displaying the remaining tiles on the second display.

After receiving the picture block receiving instruction sent by the first controller, the second controller can delete the corresponding picture block in the picture block set, so that the original position of the picture block displayed in the second display is blank, and other picture blocks which are not sent to the first controller are continuously displayed in the second display.

For example, after the tile 1 in fig. 12 is sent to the first controller, the second controller blanks the original position of the tile 1 displayed in the second display, while the other tiles (serial numbers 2 to 15) that are not sent to the first controller continue to be displayed in the second display.

A second flowchart of a method for displaying a two-screen two-system screen-switching animation according to an exemplary embodiment is illustrated in fig. 13. Referring to fig. 13, in a display device according to an embodiment of the present invention, when performing display of a dual-screen dual-system screen switching animation, specifically when adding an animation effect during switching from a large screen to a small screen, a first controller is configured to perform the following steps:

and S21, receiving each picture block sent by the second controller.

S22, when the tile reception is completed, a tile reception command is generated and sent to the second controller.

And S23, sequentially displaying the picture blocks corresponding to the picture block receiving instructions in the first display according to the receiving time sequence.

The first controller receives each picture block sent by the second controller in sequence, and generates a corresponding picture block receiving instruction immediately after receiving each picture block, and sends the corresponding picture block receiving instruction to the second controller, so that the second controller deletes the corresponding picture block displayed in the second display, and the effect that the picture in the second display moves to the first display in a landing mode is presented.

The first controller can display a picture block in the first display after receiving the picture block, so that the animation effect presented in the first display is obtained by sequentially displaying the corresponding picture blocks according to the receiving time sequence.

When the animation effect that the picture moves slowly, that is, the effect that the picture moves from top to bottom, is presented, the first controller may sequentially display the corresponding picture blocks according to a certain order.

In this embodiment, while each of the picture blocks is displayed in turn in the first display, the first controller is further configured to:

and 231, selecting an idle area positioned at the front end as a target display area in the display interface of the first display according to the preset animation receiving direction, wherein the idle area is an area in which the picture block is not displayed in the display interface.

Step 232, displaying the picture block corresponding to the picture block receiving instruction generated at the current receiving time in the target display area.

If the preset animation receiving direction is from left to right, in the display interface of the first display, the idle area positioned at the front end is the leftmost area in the display interface, and the area is used as a target display area, so that the picture block corresponding to the current receiving time is displayed in the target display area.

Fig. 14 is a schematic diagram illustrating division of a region of a first display according to an exemplary embodiment. Referring to fig. 14, when the first display does not display any picture block, the display interface of the first display is a complete free area. If part of the picture blocks are already displayed in the first display in the process of presenting the animation effect, for example, the area a is the area where the picture blocks are already displayed, the area B + C is a free area, the free area located at the front end is close to the area a where the picture blocks are already displayed according to the preset receiving direction, that is, the area B is the free area at the front end, that is, a target display area, and the target display area is used for displaying the picture blocks sent by the second controller at the current receiving time.

In order to present the animation effect of descending from top to bottom, the free area can be cut according to the cutting requirement adopted when the designated picture is divided, namely the free area is divided into a plurality of sub-areas, the width of each sub-area is the same as that of each picture block, namely, a certain picture block in the second display can vertically descend at the corresponding position of the first display.

Because the size of the two displays is different in the dual-screen display device adopted in this embodiment, and the size of the second display is larger than that of the first display, in order to enable the picture blocks in the second display to be correspondingly displayed at the corresponding positions of the first display and enable the first display to completely display the picture block set presented by the second display in the initial animation state, when the first controller receives each picture block, the first controller needs to perform animation drawing on the picture block, so as to obtain the modified picture block.

Specifically, the first controller is further configured to:

and 2321, acquiring the size, occupied position size and target display area size of the picture block in the second display.

And 2322, calculating the size proportional relation between the picture block and the target display area.

Step 2323, the received picture block is scaled according to the size proportion relation, and the modified picture block is obtained.

And 2324, displaying the modified picture block in the target display area.

The first controller may scale down the received picture block according to a size proportional relationship of the sub-area and the picture block displayed in the second display when receiving the picture block. For example, referring to fig. 12, after the second controller sends the tile 1 to the first controller, the first controller calculates the size ratio of the first target display area to the position size of the second display occupied by the tile 1 and the tile 1, and then reduces the received tile 1 according to the size ratio to obtain a modified tile 1' to be displayed in the first target display area.

An animation effect diagram of a second move of a tile from top to bottom according to an exemplary embodiment is illustrated in FIG. 15. Referring to fig. 15, after the first controller completes the display of the tile 1', the second controller transmits the tile 2 to the first controller. After the first controller receives the picture block 2, a picture block receiving instruction is generated and sent to the second controller, the second controller deletes the picture block 2 in the second display, blanks are displayed at the original position of the picture block 2 displayed in the second display, and other picture blocks (serial numbers 3 to 15) which are not sent to the first controller are continuously displayed in the second display. Meanwhile, the first controller receives the picture block 2, calculates the size proportion of the second target display area to the picture block 2, and reduces the size of the received picture block 2 according to the size proportion to obtain a picture block 2' which is displayed in the second target display area.

According to the preset animation receiving direction, the second target display area is positioned at the right side of the first target display area, namely, the picture block 2 'is displayed at the right side of the picture block 1'. The second controller sequentially sends the picture blocks in the second display to the first controller according to a preset animation sending direction; and the first controller sequentially displays the received picture blocks in the first display according to a preset animation receiving direction. Therefore, in the process of switching from a large screen to a small screen, the display equipment presents an animation effect according to the preset animation sliding direction, namely, the second display moves the appointed picture to the first display slowly in a downward falling mode.

In order to enable the animation effect to be faster and smoother in the process of switching from the large screen to the small screen, the display device provided by the embodiment of the invention can synchronously present animation materials, namely picture blocks, in the first display and the second display. That is, each tile disappears in the second display, i.e., the corresponding tile is displayed in the first display. After all tiles in the second display disappear, the first display may present the animation effect of all the tiles originally displayed in the second display. Therefore, it is required to ensure that the sum of the number of the picture blocks displayed in the first display and the number of the picture blocks displayed in the second display is equal to the total number of the picture blocks in the picture block set; the picture blocks displayed in the first display and the picture blocks displayed in the second display form a set of picture blocks.

The display device provided by the embodiment can synchronously display the animation effect in the two displays when the large screen is switched to the small screen. However, when the display device is switched from the small screen to the large screen, the scheme for synchronously displaying the animation effect in the two displays may be the same as the scheme provided in the above-described embodiment.

A third flowchart of a method for displaying a two-screen two-system screen-switching animation according to an exemplary embodiment is illustrated in fig. 16. Referring to fig. 16, in a display device according to an embodiment of the present invention, when performing display of a dual-screen dual-system screen switching animation, specifically when adding an animation effect during switching from a small screen to a large screen, a first controller is configured to perform the following steps:

and S31, capturing the appointed picture displayed in the first display to obtain the appointed picture.

The display device provided by the embodiment is characterized in that when the content displayed in the first display is switched to the second display for display, the animation effect added in the switching process comes from the display picture of the current display, namely the display picture in the first display.

The first controller intercepts a current displayed picture of the first display as a designated picture and stores the designated picture as an animation effect for shielding.

And S32, dividing the designated picture into a plurality of picture blocks to form a picture block set, and displaying the picture block set in the first display.

A schematic diagram of a first display displaying a set of picture blocks according to an exemplary embodiment is illustrated in fig. 17. Therefore, referring to fig. 17, the display device provided in this embodiment may cut the cut specified picture by the first controller to obtain a plurality of sub-blocks, that is, a plurality of picture blocks, where reference numerals 1 to 15 in fig. 17 exemplarily show a schematic diagram of dividing the specified picture into 15 picture blocks. The 15 picture blocks form a picture block set and are displayed in the first display so as to shield the first display in the process of picture switching. At this time, the complete picture block set displayed in the first display is the initial state of the animation effect.

In order to ensure that the animation effect is presented when the small screen is switched to the large screen, the first controller can divide the designated pictures according to the manner of presenting the animation effect. In particular, in forming a set of tiles for rendering an animation effect, the first controller is further configured to:

and step 321, acquiring a preset animation sliding direction.

And 322, equally cutting the appointed picture into a plurality of picture blocks along the direction parallel to the sliding direction of the preset animation to form a picture block set.

The preset animation sliding direction is used for representing the switching direction when the screen displays the animation. As shown in fig. 17, since the two displays are in a top-bottom structure, and the first display is located below the second display, when a picture is switched from the first display to the second display, the sliding direction of the animation is preset from bottom to top, that is, the designated picture is gradually displayed in the second display by starting from the first picture block on the left side and rising upwards, so that the effect of switching the animation from the first display to the second display is achieved.

In order to enable the designated pictures to be sequentially sent to the second controller according to a certain sequence and be sequentially displayed in the second display according to a certain sequence, the first controller determines that the cutting direction can be parallel or perpendicular to the preset animation sliding direction when the designated pictures are cut. Fig. 17 is a diagram showing the effect when the cutting direction is parallel to the preset animation slip.

In addition, in order to ensure that the time consumed by the second controller for receiving and loading each picture block is the same, and avoid the phenomenon that one part of the animation effect is displayed quickly and the other part of the animation effect is displayed slowly, in the embodiment, the first controller can equally cut the appointed pictures, so that the presentation of the animation effect is smoother and smoother. That is, each tile is the same in size and shape and is arranged in an order perpendicular to the sliding direction of the preset animation, i.e., from left to right.

In other embodiments, the designated picture may not be cut according to the equal requirement, and the cutting direction may not be parallel to the sliding direction of the preset animation, for example, perpendicular or at an angle. If the designated picture is randomly cut, the size and the shape of each formed picture block are different, and the arrangement sequence may not be in the sequence of the preset animation sliding direction. For example, if the cutting direction is perpendicular to the sliding direction of the preset animation, the arrangement sequence of the picture blocks is from top to bottom; when sending the tile to the second controller, the first controller may send the tile at the top layer of the first display to the second controller first, that is, sequentially sending the tile to the second controller from top to bottom.

If the designated picture is cut randomly, the arrangement sequence of each picture block is irrelevant to the preset animation sliding direction, at the moment, when the animation effect is presented, the first controller can mark each picture block, and send the corresponding picture block to the second controller according to the mark sequence.

And S33, sequentially sending each picture block to the second controller according to a preset animation sliding direction, so that the second controller displays each picture block received sequentially in the second display, and the preset animation sliding direction is used for representing the switching direction when the screen displays the animation.

After finishing the designated picture cutting, the first controller respectively sends each picture block to the second controller through the USB port, the Ethernet or other interfaces in sequence according to the preset animation sliding direction, so that the second controller displays the picture block in the second display after receiving one picture block, and the animation effect that the picture moves slowly from the first display to the second display is presented.

An animation effect diagram of a first bottom-up movement of a tile according to an exemplary embodiment is illustrated in fig. 18. Referring to fig. 18, when an animation effect of a slow movement of a picture is presented, that is, an effect of moving from bottom to top, a first controller may sequentially send picture blocks to a second controller according to a certain sequence.

In this embodiment, when sequentially transmitting each picture block, the first controller is further configured to:

and S331, acquiring the picture blocks which are centrally positioned at the front end according to the preset animation sending direction.

And S332, sending the picture block positioned at the front end to the second controller.

If the preset animation sending direction is from left to right, the picture block at the front end in the picture block set is the leftmost picture block, namely the picture block corresponding to the sequence number 1. When the first controller determines the picture block which is in line with the preset animation sending direction and is positioned at the front end, namely the picture block with the sequence number of 1 is determined, the first controller sends the picture block to the second controller.

S34, receiving a corresponding tile receiving instruction sent by the second controller when the tile receiving is completed.

When the second controller receives the current picture block sent by the first controller, in order to ensure the animation effect and present the effect that the picture is moving slowly, the picture block which is moved to the second controller in the first display needs to be eliminated in the first display. Therefore, in order to enable the first controller to immediately eliminate the picture blocks displayed in the first display and sent to the second controller, the second controller generates a picture block receiving instruction immediately after receiving the picture blocks and feeds the picture block receiving instruction back to the first controller.

S35, deleting the tile corresponding to the tile receiving instruction in the tile set, and displaying the remaining tiles in the first display.

After receiving a picture block receiving instruction sent by the second controller, the first controller can delete the corresponding picture block in the picture block set, so that the original position of the picture block displayed in the first display is blank, and other picture blocks which are not sent to the second controller are continuously displayed in the first display.

For example, after sending tile 1 in fig. 18 to the second controller, the first controller blanks the original position of tile 1 displayed in the first display, while the other tiles (serial numbers 2 to 15) that are not sent to the second controller continue to be displayed in the first display.

A fourth flowchart of a method of displaying a two-screen two-system screen-switching animation according to an exemplary embodiment is illustrated in fig. 19. Referring to fig. 19, in a display device according to an embodiment of the present invention, when performing display of a dual-screen dual-system screen switching animation, specifically when adding an animation effect during switching from a small screen to a large screen, a second controller is configured to perform the following steps:

and S41, receiving each picture block sent by the first controller.

S42, when the tile reception is completed, a tile reception command is generated and sent to the first controller.

And S43, sequentially displaying the picture blocks corresponding to the picture block receiving instructions in the second display according to the receiving time sequence.

The second controller receives each picture block sent by the first controller in sequence, generates a corresponding picture block receiving instruction immediately after receiving each picture block, and sends the corresponding picture block receiving instruction to the first controller, so that the first controller deletes the corresponding picture block displayed in the first display, and the effect that the picture in the first display moves to the second display in a lifting mode is presented.

And the second controller can display the picture block in the second display after receiving one picture block, so that the animation effect presented in the second display is obtained by sequentially displaying the corresponding picture blocks according to the receiving time sequence.

When the animation effect that the picture moves slowly, that is, the effect of moving from bottom to top, is presented, the second controller may sequentially display the corresponding picture blocks in the second display according to a certain order.

In this embodiment, while each of the picture blocks is displayed in turn in the second display, the second controller is further configured to:

and 431, according to the preset animation receiving direction, selecting an idle area positioned at the front end in the display interface of the second display as a target display area, wherein the idle area refers to an area where the picture block is not displayed in the display interface.

And step 432, displaying the picture block corresponding to the picture block receiving instruction generated at the current receiving time in the target display area.

And if the preset animation receiving direction is from left to right, in the display interface of the second display, the idle area positioned at the front end is the leftmost area in the display interface, and the area is used as a target display area so as to display the picture block corresponding to the current receiving time in the target display area.

Fig. 20 is a diagram illustrating division of a region of a second display according to an exemplary embodiment. Referring to fig. 20, when the second display does not display any picture block, the display interface of the second display is a complete free area. If part of the picture blocks are already displayed in the second display in the process of presenting the animation effect, for example, the area a is the area where the picture blocks are already displayed, the area B + C is a free area, the free area located at the front end is close to the area a where the picture blocks are already displayed according to the preset receiving direction, that is, the area B is used as the free area at the front end, that is, a target display area, and the target display area is used for displaying the picture blocks sent by the first controller at the current receiving time.

In order to present the animation effect rising from bottom to top, the free area can be cut according to the cutting requirement adopted when the designated picture is divided, namely the free area is divided into a plurality of sub-areas, the width of each sub-area is the same as that of each picture block, namely, a certain picture block in the first display can vertically rise to the corresponding position of the second display.

Because the size of the two displays is different in the dual-screen display device adopted in this embodiment, and the size of the second display is larger than that of the first display, in order to enable the picture block in the first display to be correspondingly displayed at the corresponding position of the second display and enable the second display to completely display the picture block set presented by the first display in the initial animation state, when the second controller receives each picture block, the picture block needs to be subjected to animation drawing to obtain the modified picture block.

Specifically, the second controller is further configured to:

step 4321, obtain the size, occupied position size and target display area size of the picture block when displayed on the first display.

Step 4322, calculate the size ratio of the tile to the target display area.

Step 4323, scaling the received picture block according to the size ratio to obtain the modified picture block.

Step 4324, display the modified tile in the target display area.

The second controller may scale down the received picture block according to a size proportional relationship of the sub-area and the picture block displayed in the first display when receiving the picture block. For example, referring to fig. 18, after the first controller sends the tile 1 to the second controller, the second controller calculates the size ratio of the first target display area to the position size of the first display occupied by the tile 1 and the tile 1, and then enlarges the received tile 1 according to the size ratio to obtain a modified tile 1' to be displayed in the first target display area.

An animation effect diagram of a second bottom-up movement of a tile according to an exemplary embodiment is exemplarily shown in fig. 21. Referring to fig. 21, after the second controller completes the display of the picture block 1', the first controller transmits the picture block 2 to the second controller. After receiving the picture block 2, the second controller generates a picture block receiving instruction to the first controller, the first controller deletes the picture block 2 in the first display, and blanks are displayed at the original position of the picture block 2 displayed in the first display, and other picture blocks (serial numbers 3 to 15) which are not sent to the second controller are continuously displayed in the first display. Meanwhile, the second controller receives the picture block 2, calculates the size ratio of the second target display area to the picture block 2, and then enlarges the received picture block 2 according to the size ratio to obtain a picture block 2' which is displayed in the second target display area.

According to the preset animation receiving direction, the second target display area is positioned at the right side of the first target display area, namely, the picture block 2 'is displayed at the right side of the picture block 1'. The first controller sequentially sends the picture blocks in the first display to the second controller according to a preset animation sending direction; and the second controller sequentially displays the received picture blocks in the second display according to a preset animation receiving direction. Therefore, in the process of switching from the small screen to the large screen, the display device presents an animation effect according to the preset animation sliding direction, namely, the first display moves the designated picture to the second display slowly in an upward lifting mode.

In order to enable the animation effect to be faster and smoother in the process of switching from the small screen to the large screen, the display device provided by the embodiment of the invention can synchronously present animation materials, namely picture blocks, in the first display and the second display. That is, each tile disappears in the first display, i.e., the corresponding tile is displayed in the second display. After all tiles in the first display disappear, the second display may present the animation effect of all the tiles originally displayed in the first display. Therefore, it is required to ensure that the sum of the number of the picture blocks displayed in the first display and the number of the picture blocks displayed in the second display is equal to the total number of the picture blocks in the picture block set; the picture blocks displayed in the first display and the picture blocks displayed in the second display form a set of picture blocks.

It should be noted that, in the above embodiments, the display device is provided, and when the first display is switched to the second display or the second display is switched to the first display, the display device is configured vertically, and the two displays are different in size.

However, in practical applications, the two displays configured in the display apparatus may also adopt a left-right structure, and the sizes of the two displays may be the same. In this case, during the process of switching between two displays, the related method provided in the foregoing embodiment may also be used, except that in this scenario, when the second controller (or the first controller) sends the picture block to the first controller (or the second controller), the first controller (or the second controller) may directly display the picture block without performing the scaling process on the picture block. And the animation effect can be in the form of moving from left to right or moving from right to left. The specific implementation process is only required to refer to the method provided by the foregoing embodiment, and is not described in detail here.

As can be seen from the foregoing technical solutions, in the display device provided in the embodiments of the present invention, when a screen is switched from one display to another display, the controller corresponding to the main switching display intercepts a designated screen displayed in the display, divides the designated screen into a plurality of picture blocks, sequentially sends each picture block to another controller, and the another controller sequentially displays each picture block in the another display according to the receiving time sequence. The main controller deletes the sent picture blocks in the picture block set and displays the rest picture blocks in the corresponding display. Therefore, when the two displays switch pictures, the picture block disappearing in one display can be immediately displayed in the other display, namely, the animation effect is presented by the moving and displaying process of the picture block according to the preset animation sliding direction, the animation effect is synchronously added on the two displays, and the past animation effect of the picture block slowly moving from one display to the other display is presented, so that the phenomena of flashing screens or blue screens and the like existing in the two displays due to the fact that the two displays cannot synchronously display the corresponding pictures are shielded. In addition, animation effects presented on the two displays of the display device can be quickly transferred across the system and played simultaneously, so that the effects of quick switching and smooth animation are achieved, and the user impression is improved.
