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, and implementation of the display device having a 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 that receives 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 picture is blocked or unsmooth. Further, due to the data processing capability of the CPU, when the CPU performs soft decoding on the video chat screen, multiple paths of 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.

Based on the consideration 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 of the present application will be described first with reference to the drawings. It should be noted that the following descriptions of the concepts are only intended to make the contents of the present application more easily understood, 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 various 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 components may generally 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 a common remote control device with a user interface in a touch screen.

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

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 generally referred to as a motherboard (or chip).

A schematic diagram of an operation scenario between a display device and a control apparatus is exemplarily shown in fig. 1. 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 be installed with a software application, so that connection communication between the two may be implemented through a network communication protocol, and thus, the purpose of one-to-one control operation and data communication may be implemented. Such as: a control instruction protocol can be established between the mobile terminal 100B and the display device 200, the remote control keyboard is synchronized to the mobile terminal 100B, and the function of controlling the display device 200 is realized by controlling the user interface on the mobile terminal 100B; the audio and video contents 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 time, weather, temperature, reminder messages, 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 a multi-party interactive picture while displaying a 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 it will be understood by those skilled in the art that the display device 200 may be modified in its performance and configuration as desired.

The display apparatus 200 may additionally provide an intelligent network television function providing a computer support function in addition to the broadcast receiving television 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 while entering a gaming application to participate in a game. Figuratively, the function may be said to be "play while looking".

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 posture and the motion of the human body, the limb detection and tracking and the detection of the key point data of the human skeleton are obtained through the camera, and then the detection is fused with the animation in the game, so that the game of the 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". Alternatively, 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 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 device 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 implement a certain function, and the second controller 310 and the first controller 210 cooperate to implement a certain function.

Fig. 9a schematically shows a user interface in the display device 200. As shown in fig. 9a, 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 will be described in detail below. Illustratively, the first view display 2011 includes layout of 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 can be moved by user input to change 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 that 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 a user input. Illustratively, the focus object position is implemented or identified by drawing a thick line at 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 tangible or intangible to be recognized by a user, such as a form such as a 3D distortion of an item, and may also change the identification of a border line, size, color, transparency, and outline and/or font of the text or image of the item in focus.

Referring to the embodiment shown in fig. 1-9 a, the display device includes a first display 280, a first controller 210, a second display 380, and a second controller 310. As shown in fig. 1, the first display and the second display have different display sizes, the first display with a larger size plays a main display role, which is also called a main screen, and the second display with a smaller size plays an auxiliary display role, which is also called a sub screen.

The first controller 210 controls the operation of the display device 200 and responds to user operations associated with the first display 280 by running various software control programs (e.g., an operating system and/or various application programs) stored on the memory 290. For example, control presents a user interface on the first display 280, the user interface including a number of UI objects thereon; in response to a received user command for a UI object on the user interface, the first controller 210 may perform an operation related to the object selected by the user command.

The second controller 310 controls the operation of the display device 200 and responds to user operations associated with the second display 380 by running various software control programs stored on the memory 390 (e.g., with installed third party applications, etc.), as well as interacting with the first controller 210. For example, the second controller 310 may control presentation of a user interface including several UI objects on the user interface on the second display 380, and in response to a received user command for a UI object on the user interface, may perform an operation related to the object selected by the user command.

For ease of illustration, the user interface presented on the first display 280 is referred to as a first user interface, and the user interface presented on the second display 380 is referred to as a second user interface. Alternatively, the first user interface and the second user interface may display home pages of operating systems run by the first controller and the second controller, respectively.

Fig. 9b exemplarily shows a play screen provided by the display device, and the play screen is composed of a first user interface presented on the first display and a second user interface presented on the second display, as shown in fig. 9 b. One or more of interface elements, video frames, picture frames, etc., such as the home page displayed on the first display in fig. 9b, may be displayed in the first user interface and/or the second user interface.

Fig. 9b to 12 show exemplary interaction procedures for causing the first display to present a GUI by operating the control device.

When the first display displays the first user interface as shown in fig. 9b, the user may input a menu item display instruction by operating the control device 100 (e.g., the remote controller 100A) to instruct the display apparatus to present a setting menu of the second display on the first display, the setting menu having an item for adjusting the backlight brightness of the second display thereon. When the first controller receives the menu item display instruction input by the user, the setting menu of the second display is controlled to be presented on the first display in response to the menu item display instruction.

The following describes a user interface interaction process of the display device to present a setting menu of the second display, with reference to fig. 10 to 12.

First, on the interface shown in fig. 9b, a user may input a user instruction indicating to display a system menu by activating a "menu" key on the control device, the first controller may present a user interface as shown in fig. 10 on the first display in response to the user instruction, the user interface having a menu option page 90 displayed therein, the menu option page 90 containing a plurality of items 91-97, and a selector 98 displayed to indicate that any one of the items is selected, the user may move the position of the selector 98 in the user interface by operating the input of the control device to change the selection of a different item.

Next, in fig. 10, when a user operates the control device to input a user instruction indicating that the selector 98 selects the item 96, the first controller may present a user interface as shown in fig. 11, in which a main setting menu page ("AI setting") 96 is displayed, on the first display in response to the user instruction, the main setting menu page 96 corresponding to detailed menu options of the item 96, i.e., the items 961 and 967. Thereafter, in fig. 11, when a user operates the control device to input a user instruction instructing the selector 98 to select an item 964, the first controller may present, on the first display, a user interface as shown in fig. 12 in which a setting menu ("sub-screen setting") 964 of the second display containing detailed menu options corresponding to the item 964, that is, the item 9641 and 9644, is displayed in response to the user instruction.

As described previously, on the setting menu of the second display presented on the first display, there are one or more items for adjusting the backlight brightness of the second display, such as the item 9661 ("sub-screen brightness") and the item 9662 ("do-not-disturb") shown in fig. 12.

In some embodiments, the items for adjusting the backlight brightness of the second display each correspond to different adjustment rules, such as scaling, i.e. adjusting the backlight brightness in response to the user adjusting the brightness value on the user interface in an equal proportion, or automatically adjusting the backlight brightness in response to the preset condition being met.

When the first display displays the setting menu as shown in fig. 12, the user can operate an item for adjusting the brightness of the second display on the setting menu by operating the control means, and when the first controller receives a user operation of the item by the user, the brightness of the second display is adjusted in response to the operation according to the adjustment rule corresponding to the operated item.

For example, the item for adjusting the brightness of the second display may be a first item for scaling the brightness of the second display, such as item 9641 ("sub-screen brightness") shown in fig. 12. The user can input the brightness value of the second display by operating the first item, and the first controller can adjust the backlight brightness of the second display to the brightness value input by the user.

For example, as shown in fig. 12, the user may instruct the selector 98 to select the item 9661 by operating the control device, and the first controller presents a user interface as shown in fig. 13, in which a brightness adjustment bar is displayed, on the first display in response to the user operation. On the user interface shown in fig. 13, the user can trigger the left or right direction key on the control device to turn down or turn up the brightness value.

As can be seen from the above example, the user may modify the brightness value of the second display based on interaction with the first item and the brightness adjustment bar. Meanwhile, based on the operation of the user on the first item and the brightness adjustment bar, the first controller may receive a brightness value input by the user, and then, may adjust the backlight brightness of the second display to the brightness value input by the user.

In a specific implementation, the luminance value corresponds to the PWM value in equal proportion, the first controller may convert the luminance value input by the user into a corresponding PWM signal, transmit the PWM signal to the communication bus (I2C), and input the PWM signal to the second display driving board 34 in a manner of reading/writing the GPIO interface on the second display driving board 34 through the communication bus, so that the second display driving board 34 performs backlight luminance control on the second backlight assembly 22 according to the input PWM signal.

As another example, the item for adjusting the brightness of the second display is a second item for automatically adjusting the brightness of the second display, such as item 9642 ("do not disturb") shown in fig. 12. The user can input a time length threshold value for triggering automatic adjustment of the brightness of the second display by operating the second item, so that when the topmost page displayed by the second display is an operating system homepage of the second controller and the display time length reaches the time length threshold value, the first controller adjusts the backlight brightness of the second display to a preset low brightness.

For example, as shown in fig. 12, the user may instruct the selector 98 to select an item 9642 by operating the control means, and the first controller may present, on the first display, a user interface as shown in fig. 14 in which a plurality of items 96421 and 96426 are displayed, which correspond to the toggle button of the "do not disturb" function and the time threshold option provided by the display device, respectively, in response to the user operation. In the user interface shown in fig. 14, the user may operate the control device to select an item, to input a time threshold corresponding to the selected item, for example, 2 minutes as shown in fig. 14, or to input a user instruction for turning off the "do not disturb" function.

During specific implementation, the first controller sends the brightness value input by the user to the second controller, and the second controller stores the brightness value as a system attribute value after receiving the brightness value. The second controller acquires a topmost page (top activity) displayed by the second display and monitors switching of the topmost page, judges whether the topmost page is a homepage (Launcher) of an operating system operated by the second controller, times the display duration of the topmost page when the homepage is the topmost page, and sends a first message to the first controller when the display duration of the topmost page of the homepage reaches a duration threshold value to instruct the first controller to adjust the backlight brightness of the second display to a preset low brightness from the current brightness.

The preset low brightness is a brightness value pre-stored by the first controller. Optionally, the preset low brightness value is lower than the user set brightness of the first display and lower than the user set brightness value of the second display, but is not limited thereto.

It should be added that if it is detected that the homepage exits from the topmost page when the display time of the homepage on the topmost page does not reach the time threshold, that is, the topmost page is switched from the homepage to other pages except the homepage, the timing is stopped.

Thus, when there is no interaction or push on the second display, the backlight brightness will automatically be turned down after a period of time (duration threshold) has passed, making the second display visually blend into the display device bezel and base, and not bothering the user when the user inputs operations related to the first display.

In some embodiments, if the brightness of the second display is the preset low brightness, when the second controller detects that the topmost page displayed on the second display is switched from the main page to an interface other than the main page, the second controller sends a second message to the first controller, so as to instruct the first controller to adjust the brightness of the second display from the preset low brightness to a brightness value set by a user, so as to ensure that the second display normally presents the picture content.

It should be noted that the process of adjusting the brightness of the second display by the first controller in response to receiving the first message or the second message is the same as the process of adjusting the brightness of the second display by the second controller in response to the operation of the first item by the user, and is not described herein again.

It can be seen from the foregoing embodiments that, when the first display presents the first user interface, the first controller may present, in response to a menu item display instruction input by a user, a setting menu of the second display on the first display, and may adjust, in response to a user operation on an item on the setting menu for adjusting the brightness of the second display, the backlight brightness of the second display according to an adjustment rule corresponding to the item.

The items for adjusting the brightness of the second display can comprise a first item and/or a second item, the first item is used for adjusting the brightness of the second display in proportion, so that the display device supports a user to actively adjust the brightness of the second display through setting a menu, the second item is used for automatically adjusting the brightness of the second display, so that the display device supports that interaction and pushing do not exist on the second display, the brightness is automatically adjusted to be low after a period of time, the display device is integrated with a frame and a base of the display device in appearance, and the user cannot be disturbed when the user inputs operation related to the first display.
