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

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

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

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

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.

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.

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

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 device

200. For example, Android (Android) and various APPs may be independently installed on the

second controller

310 and the

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.

The embodiment of the application further provides a method for adjusting the backlight brightness of the display device. Fig. 15 and 16 exemplarily show an adjustment method of the backlight luminance of the display device.

In connection with the method flowchart shown in fig. 15, the method may be performed by the first controller, and the method includes the following steps, but is not limited thereto.

Step

101, presenting a first user interface on a first display; such as the first user interface shown in fig. 8.

And 102, receiving a menu item display instruction input by a user on the first user interface, wherein the menu item display instruction indicates that a setting menu of a second display is displayed.

The user can input the above menu item display instruction by operating the control device, for example, pressing one or more times a menu key, a direction key, an OK key, etc. on the control device.

Step

103, responding to the menu item display instruction, presenting a setting menu of the second display on the first display, wherein the setting menu comprises an item for adjusting the brightness of the second display;

the setting menu of the second display may be the setting menu 966 in the first user interface shown in fig. 12. The items on the setup menu for adjusting the brightness of the second display may be as shown in fig. 12 as item 9661 ("sub-screen brightness") and item 9662 ("do not disturb").

And 104, responding to the operation of the user on the item, setting the brightness of the second display, and adjusting the brightness of the second display to the target brightness.

In some embodiments, the item for adjusting the brightness of the second display comprises a second item for automatically adjusting the brightness of the second display. Based on this, step 104 may specifically include receiving a brightness value input by the user through operation of the first item, where a brightness corresponding to the brightness value input by the user is the target brightness; the brightness of the second display is then adjusted to the brightness value entered by the user.

In still other embodiments, the items for adjusting the brightness of the second display include a second item for automatically adjusting the brightness of the second display. In connection with the method flowchart shown in fig. 16,

step

104 may include the following steps:

and 1041, receiving a time length threshold value input by the user through operating the second item.

The duration threshold is used for triggering automatic adjustment of the brightness of the second display, and the automatic adjustment specifically comprises: when the topmost page displayed by the second display is a home page and the display time length reaches the time length threshold value, adjusting the brightness of the second display to a preset low brightness, wherein the preset low brightness is the target brightness

And 1042, sending the duration threshold to a second controller.

Step

1043, when a first message sent by the second controller is received, adjusting the brightness of the second display to a preset low brightness, where the first message is sent when the second controller sends a display time length reaching a time length threshold when the topmost page displayed by the second display is a home page.

Step

1044, when a second disappearance sent by the second controller is received, adjusting the brightness of the second display to the brightness value input by the user, where the second message is sent when the second controller monitors that the topmost page displayed by the second display is switched from the home page to another interface other than the home page when the brightness of the second display is the preset low brightness.

In the above example, the process of the first controller adjusting the brightness of the second display comprises: the first controller converts the brightness value or the preset low brightness input by the user into a corresponding PWM signal according to the corresponding relationship between the brightness value and the PWM value, transmits the PWM signal to the communication bus (I2C), and inputs the PWM signal to the second

display driver board

34 in a way of reading/writing the GPIO interface on the second

display driver board

34 through the communication bus, so that the second

display driver board

34 performs backlight brightness adjustment control on the

second backlight assembly

22 according to the input PWM signal.

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.
