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. 9a illustrates a schematic diagram of 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 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 conversion between an internal form of information and 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. "zoomable," may mean that the first view display area 2011 is zoomable in size or proportion on the screen, and the items in the first view display area 2011 are zoomable 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.).

"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.

In some embodiments, 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, controlling the presentation of a user interface including a number of UI objects on the user interface on the second display 380, the second controller 310 may perform an operation related to an object selected by a user command in response to the received user command for the UI object on the user interface.

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. In an exemplary embodiment, the first user interface and the second user interface may display home pages of operating systems on which the first controller and the second controller are run, 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 screens, picture screens, 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.

In order to solve the problem that too many operable items cannot be displayed in the second user interface due to the size of the second display/second user interface, in the embodiment of the present application, a setting menu of the second display is displayed in the second user interface, the setting menu includes the operable items acting on the second display, and then, the user can input an operation in the second user interface to control the second display.

Fig. 9b to 12 show schematically an interaction process for causing the first display to present a GUI by operating the control means.

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 a plurality of items thereon, such as an item for setting a push function, an item for adjusting backlight brightness of the second display, and the like, wherein the push function is to display push information in the second user interface. 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.

A user interface interaction process in which the display device presents the setting menu of the second display is explained below with reference to fig. 10 to 12.

First, on the interface shown in fig. 9b, a user may input a user instruction indicating a menu of the display system 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, and 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, i.e., the item 9641 and 9644, is displayed in response to the user instruction.

As described above, on the setting menu of the second display presented on the first display, there are a plurality of items, such as the item 9661 ("sub-screen brightness"), the item 9662 ("do not disturb"), the item 9663 ("smart life"), and the item 9664 ("sub-screen theme") shown in fig. 12. Among them, item 9661 ("sub-screen brightness") and item 9662 ("do not disturb") are used to adjust the backlight brightness of the second display, item 9663 ("smart life") is used to turn on or off the push function applied on the second display, i.e. to display push information on the second user interface, and item 9664 ("sub-screen theme") is used to set the interface theme of the second user interface.

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 according to the adjustment rule corresponding to the operated item in response to the operation.

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 33 in a manner of reading/writing the GPIO interface on the second display driving board 33 through the communication bus, so that the second display driving board 33 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 switch 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 obtains 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 homepage at 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 homepage at the topmost page reaches a duration threshold value so as to instruct the first controller to adjust the backlight brightness of the second display from the current brightness to a preset low brightness.

The preset low brightness is a brightness value pre-stored by the first controller. In an exemplary embodiment, 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 no interaction or push exists on the second display, the backlight brightness of the second display is automatically reduced after a period of time (duration threshold) so that the second display is integrated with the frame and the base of the display device in appearance, and the user is not disturbed when the user inputs the operation related to the first display.

In some embodiments, if the brightness of the second display is the preset low brightness, if the second controller monitors that the topmost page displayed by the second display is switched from the homepage to another interface except the homepage, the second controller sends a second message to the first controller 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 details are not repeated here.

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

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 carrying out proportion adjustment on the brightness of the second display, so that the display device supports a user to carry out active adjustment on the brightness of the second display through a menu, the second item is used for carrying out automatic adjustment on the brightness of the second display, and therefore when 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.

In some embodiments, the second display has an item for turning on or off the push function on a setting menu, and the user can operate the item on the setting menu by operating the control device to turn on or off the push function. For example, as shown in fig. 12, the user may move the position of the selector to drop the selector into an item 9663 ("wisdom life") and operate the decision key to turn the push function on or off. The controller acquires the push information and displays the push information in the second user interface under the condition that the push function is started. Therefore, the user can obtain the experience of receiving message pushing on the display equipment, and the displayed pushing information cannot block the content watched by the user.

In some embodiments, the push information includes, but is not limited to, pictures, posters, text, and the like.

In some embodiments, the pushing information may specifically include: weather information, history records (such as video watching records) of application login accounts, various types of updating information (such as drama update and order progress provided by an application), various types of recommendation information (such as commodity recommendation and new film/program recommendation), real-time/hot information, various types of help information (such as how to shut down, how to use a voice function and the like) and the like. For example, weather information is displayed in the second user interface shown in fig. 9, and a new message alert is displayed in the second user interface shown in fig. 9.

Due to the fact that the pushed information is complicated and complicated, in order to improve the pushing effect and ensure that the pushed information draws attention of a user, in some embodiments, a pushing sequence is preset, and when pushing is needed, the pushed information is displayed in the second user interface according to the preset sequence.

In some embodiments, the controller detects whether the push function is started in response to the startup of the display device, and if the push function is started, acquires at least one piece of push information and displays the at least one piece of push information in the second user interface according to a preset sequence; if the push function is closed, the process is ended, i.e. the step of pushing the information to the second display is not executed.

In a specific implementation, the open state or the closed state of the push function may be saved as a system attribute, and the open state and the closed state are represented by different attribute values, for example, when a user operates to open the push function, an attribute value 1 is saved, and when a user operates to close the push function, an attribute value 0 is saved. The controller may detect whether the push function is enabled by obtaining the attribute value of the attribute.

In some embodiments, not only the push information is pushed to the second user interface according to the preset sequence, but also a display duration may be set for each piece of push information in advance. The preset display durations corresponding to different push information may be the same or different. When the push information is displayed, timing the display duration of the current push information, canceling the display of the push information when the display duration of the current push information reaches the corresponding preset display duration, and displaying the next piece of push information. Therefore, for each piece of push information, after the display time of the push information reaches a certain value, the push information automatically disappears in the second user interface, and user operation is not needed, so that user experience can be provided.

In some embodiments, after the last piece of push information is displayed, the backlight brightness of the second display is reduced to the preset low brightness, so that the second display is integrated with the frame and the base of the display device in appearance, and the user is not disturbed when the user inputs the operation related to the first display.

Illustratively, push information such as weather, history, drama updates, member notifications, order progress, hotspot information, new-film recommendations, good recommendations, voice help, etc. is displayed in the second user interface in the following order and display duration.

Sequence of	Push information name	Display duration/second
			1	Weather (weather)	15
2	History record	10
			3	Series update	10
4	Member notification	10
			5	Order progress	10
6	Hot spot information	15
			7	New film recommendation	10
8	Good item recommendation	10
			9	Voice help	10

It should be noted that the above-mentioned pushing sequence and the displaying time duration are only an exemplary embodiment, and those skilled in the art may adjust the pushing sequence and the time duration as needed, and may also set different pushing times for different pushing information, for example, pushing the weather of the day before 18:00 a day, pushing the message of the tomorrow after 18:00 a day, pushing the weather of the future week at 12:00 a noon of each day, and so on. In addition, information pushing can be increased or decreased according to user operation. The number of push pieces can be set for each class of push information, for example, after the mobile terminal is started up, the push information of three good object recommendation classes is obtained and displayed in the second user interface in sequence.

The display device provided by the embodiment of the application can utilize the second display to display the push information by adding the second display below the first display playing a main display role, so that a user can obtain experience of receiving message push on the display device, and the content displayed on the first display cannot be shielded. The operable items acting on the second display (i.e., the items in the setting menu of the second display) are displayed in the first user interface, which facilitates the user operation and avoids inconvenience caused by the small size of the second display.

An interactive control method may be executed by the first controller in conjunction with the method flowchart shown in fig. 15, but is not limited to this, and referring to fig. 15, the method may include:

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