In some embodiments, a user may input a user command through a Graphical User Interface (GUI) displayed on the display 260, and the user input interface receives the user input command through the Graphical User Interface (GUI). Alternatively, the user may input the user command by inputting a specific sound or gesture, and the user input interface recognizes the sound or gesture through the sensor to receive the user input command.

In some embodiments, a "user interface" is a media interface for interaction and exchange of information 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 commonly used presentation form of the user interface is a graphical user interface (Graphic User Interface, GUI), which refers to a user interface related to computer operations that is displayed in a graphical manner. It may be an interface element such as an icon, a window, a control, etc. displayed in a display screen of the electronic device, where the control may include a visual interface element such as an icon, a button, a menu, a tab, a text box, a dialog box, a status bar, a navigation bar, a Widget, etc.

In some embodiments, the display device 200 may be a touch display device, where the display device is a touch display formed by a touch component and a screen. The touch display device supports the touch interaction function, and a user can operate the host only by lightly touching the display with fingers, so that the operations of a keyboard, a mouse and a remote controller are eliminated, and man-machine interaction is more straightforward. On the touch display, the user can input different control instructions through touch operations. For example, a user may input touch instructions such as clicking, sliding, long pressing, double clicking, etc., and different touch instructions may represent different control functions.

To implement the different touch actions, the touch assembly may generate different electrical signals when the user inputs the different touch actions, and transmit the generated electrical signals to the controller 250. The controller 250 may perform feature extraction on the received electrical signal to determine a control function to be performed by the user based on the extracted features. For example, when a user enters a click touch action at any program icon location in the application program interface, the touch component will sense the touch action and thereby generate an electrical signal. After receiving the electrical signal, the controller 250 may determine the duration of the level corresponding to the touch action in the electrical signal, and recognize that the user inputs the click command when the duration is less than the preset time threshold. The controller 250 then extracts the location features generated by the electrical signals to determine the touch location. When the touch position is within the application icon display range, it is determined that a click touch instruction is input by the user at the application icon position. Accordingly, the click touch instruction is used to perform a function of running a corresponding application program in the current scenario, and thus the controller 250 may start running the corresponding application program.

For another example, when the user inputs a sliding motion in the media presentation page, the touch assembly also sends the sensed electrical signal to the controller 250. The controller 250 first determines the duration of the signal corresponding to the touch action in the electrical signal. When the duration time is determined to be longer than the preset time threshold value, the position change condition generated by the signals is judged, and obviously, the generation position of the signals changes for the interactive touch action, so that the user is determined to input a sliding touch instruction. The controller 250 then determines the sliding direction of the sliding touch command according to the change condition of the signal generating position, and controls the page turning of the display screen in the media display page so as to display more media options. Further, the controller 250 may further extract characteristics such as a sliding speed and a sliding distance of the sliding touch instruction, and perform a picture control of turning pages according to the extracted characteristics, so as to achieve a following effect.

Similarly, for the touch instructions such as double-click and long-press, the controller 250 may extract different features, determine the type of the touch instruction through feature judgment, and execute corresponding control functions according to a preset interaction rule. In some embodiments, the touch assembly also supports multi-touch, such that a user may enter touch actions on the touch screen via multiple fingers, e.g., multi-finger clicks, multi-finger long presses, multi-finger swipes, etc.

The touch control action can be matched with a specific application program to realize a specific function. For example, after the user opens the drawing board application, the display 260 may present a drawing area, the user may draw a specific touch action track in the drawing area through the sliding touch instruction, and the controller 250 determines a touch action pattern through the touch action detected by the touch component and controls the display 260 to display in real time, so as to satisfy the demonstration effect. For example, it is a basic function of a touch screen display device that a user rotates a finger touching a display to control the display to display a picture. The current interaction mode is that after a plurality of fingers rotate on a screen, the picture immediately rotates to a horizontal or vertical angle according to the rotation direction of the fingers, no interaction process exists, and the user experience is poor.

In some embodiments, a system of display devices may include a Kernel (Kernel), a command parser (shell), a file system, and an application program. The kernel, shell, and file system together form the basic operating system architecture that allows users to manage files, run programs, and use the system. After power-up, the kernel is started, the kernel space is activated, hardware is abstracted, hardware parameters are initialized, virtual memory, a scheduler, signal and inter-process communication (IPC) are operated and maintained. After the kernel is started, shell and user application programs are loaded again. The application program is compiled into machine code after being started to form a process.

Referring to FIG. 4, in some embodiments, the system is divided into four layers, from top to bottom, an application layer (referred to as an "application layer"), an application framework layer (Application Framework layer) (referred to as a "framework layer"), a An Zhuoyun row (Android run) and a system library layer (referred to as a "system runtime layer"), and a kernel layer, respectively.

In some embodiments, at least one application program is running in the application program layer, and these application programs may be a Window (Window) program of an operating system, a system setting program, a clock program, or the like; or may be an application developed by a third party developer. In particular implementations, the application packages in the application layer are not limited to the above examples.

The framework layer provides an application programming interface (application programming interface, API) and programming framework for the application. The application framework layer includes a number of predefined functions. The application framework layer corresponds to a processing center that decides to let the applications in the application layer act. Through the API interface, the application program can access the resources in the system and acquire the services of the system in the execution.

As shown in fig. 4, the application framework layer in the embodiment of the present application includes a manager (manager), a Content Provider (Content Provider), and the like, where the manager includes at least one of the following modules: an Activity Manager (Activity Manager) is used to interact with all activities that are running in the system; a Location Manager (Location Manager) is used to provide system services or applications with access to system Location services; a Package Manager (Package Manager) for retrieving various information about an application Package currently installed on the device; a notification manager (Notification Manager) for controlling the display and clearing of notification messages; a Window Manager (Window Manager) is used to manage bracketing icons, windows, toolbars, wallpaper, and desktop components on the user interface.

In some embodiments, the activity manager is used to manage the lifecycle of the individual applications as well as the usual navigation rollback functions, such as controlling the exit, opening, fallback, etc. of the applications. The window manager is used for managing all window programs, such as obtaining the size of the display screen, judging whether a status bar exists or not, locking the screen, intercepting the screen, controlling the change of the display window (for example, reducing the display window to display, dithering display, distorting display, etc.), etc.

In some embodiments, the system runtime layer provides support for the upper layer, the framework layer, and when the framework layer is in use, the android operating system runs the C/C++ libraries contained in the system runtime layer to implement the functions to be implemented by the framework layer.

In some embodiments, the kernel layer is a layer between hardware and software. As shown in fig. 4, the kernel layer contains at least one of the following drivers: audio drive, display drive, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (e.g., fingerprint sensor, temperature sensor, pressure sensor, etc.), and power supply drive, etc.

Based on the display device, the display device can support the rotation and/or lifting functions by adding the driving component and the gesture detection component. Typically, the drive assembly includes a rotation assembly and/or a lift assembly with which the controller 110 may communicate to control the rotation assembly to drive the display to rotate when it is desired to rotate the display and to control the lift assembly to drive the display to raise or lower when it is desired to raise or lower the display.

In a possible implementation manner, the rotating component and/or the lifting component are provided with a GPIO interface, and the controller changes the GPIO interface state of the rotating component and/or the lifting component by reading the GPIO interface. When the state of the GPIO interface is changed, the rotating component and/or the lifting component drive the display to rotate and/or lift according to the changed state of the GPIO interface.

In a possible implementation, the lifting assembly and/or lifting assembly includes an MCU chip on which a bluetooth module is integrated, such that the lifting assembly and/or lifting assembly supports bluetooth functions, such as Bluetooth Low Energy (BLE), and further, the controller 110 may communicate with the lifting assembly and/or lifting assembly based on a bluetooth protocol.

In some embodiments, the detection assembly includes a sensor for detecting a rotational state of the display and a sensor for detecting a display lift state. During the rotation or lifting process of the display, the controller monitors the rotation state or lifting state of the display in real time according to the data detected by the gesture detection assembly. For example, in the process of controlling the rotation of the display, information such as the rotation angle, the angle speed and the like is acquired by monitoring the data of the sensor. In the process of controlling the lifting of the display, the information such as the lifting distance, the lifting speed and the like is obtained by monitoring the data of the sensor.

In some embodiments, the detection assembly is included in the drive assembly. For example, a sensor for detecting the rotation state of the display is included in the rotation assembly, and forms the rotation assembly together with the rotation assembly. The sensor for detecting and displaying the lifting state is arranged on the lifting assembly and forms the lifting assembly together with the lifting assembly.

Fig. 5 is a schematic rear view of a display device according to the present application, which includes a display 260 and a lift driving device 511, as shown in fig. 5, in some exemplary embodiments. The elevation driving apparatus 511 includes an elevation guide rail fixed to the bracket 512. The rotation driving device is then arranged inside the lifting driving device, i.e. between the lifting driving device and the display, not shown in fig. 5.

In some embodiments, controller 250 controls the operation of display device 200 and responds to user operations associated with display 260 by running various software control programs (e.g., an operating system and/or various application programs) stored on memory. For example, control presents a user interface on a display, 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 controller 250 may perform an operation related to the object selected by the user command.

The display device provided by the application has the function of a drawing board. The palette function is implemented based on a palette function related application installed on the display device. For ease of description, the palette function related application will be referred to as a palette application.

In some embodiments, some or all of the steps involved in embodiments of the present application are implemented within an operating system and in an application. In some embodiments, the application program used to implement some or all of the steps of embodiments of the present application is the "palette application" described above, which is stored in memory, and the controller 250 controls the operation of the display device 200 and responds to user operations associated with the application program by running the application program in an operating system.

It should be noted that the display device according to the embodiment of the present application includes, but is not limited to, the display device 200 described in the above embodiment, and may also be other terminal devices having an image display function, a data processing function, and an information receiving and transmitting function, such as a mobile phone, a tablet computer, and other portable mobile terminals. Hereinafter, embodiments of the present application will be described in detail by taking a display device as an example.

After the display device starts the palette application, an electronic palette interface is presented on the display. An electronic palette interface displays areas of user interface objects, information, and/or inputtable content corresponding to one or more functions of the palette application. The aforementioned user interface objects refer to objects that make up the electronic palette interface and may include, but are not limited to, text, images, icons, soft keys (or "virtual buttons"), drop-down menus, radio buttons, check boxes, selectable lists, and the like. The displayed user interface objects may include non-interactive objects for conveying information or constituting the appearance of the user interface, interactive objects available for user interaction, or a combination of non-interactive objects and interactive objects. The user may interact with the user interface object by making contact with the touch screen at a location of the touch screen corresponding to the interactive object with which the user wishes to interact. The display device detects a contact and responds to the detected contact by performing an operation corresponding to interaction of the interactive object.

In some embodiments, the electronic palette interface includes a drawing area and a control area. The drawing area is an area capable of inputting contents, and the control area is used for intensively displaying user interface objects and information corresponding to one or more functions of the drawing board application. The user interface object includes, but is not limited to, a brush control, an erasure control, a sharing control, and the like, and the information includes various parameter information corresponding to the brush control, such as a current input color, an optional color, thickness, line shape, and the like.

FIG. 6 is an electronic palette interface shown in some embodiments of the application. As shown in fig. 6, the electronic palette interface includes a drawing area 610 and a control area 620. The drawing area 610 is used for receiving content input by a user through a control in the control area 620, and displaying part or all of an area of a layer of the received content, and the content received by the drawing area 610 may be at least one of lines, graphics, and characters. The control section 620 is a part or all of a layer for displaying various functional controls, and the functional controls displayed by the control section 620 include at least one of a brush control 621, an erasure control 622, a cut control 623, a delete control 624, a video control 625, a share control 626, a cancel control 627, a restore control 628, a save control 629, and a close application control 630.

In some embodiments, referring to fig. 7, the layer to which the control area 620 belongs may be superimposed on the layer to which the drawing area 610 belongs, and the user may select the layer to which the control area 620 belongs, and move the layer to which the control area 620 belongs to any position on the layer to which the drawing area 610 belongs through touch drag.

In some embodiments, when the middle brush control 621 is selected, the corresponding brush toolbar 700 of the brush control is triggered and displayed, and referring to fig. 8, the brush type, line color, line type, line thickness, and the like may be selected in the brush toolbar 700. The user selects the target type of brush control 621 to pick up the brush, and after picking up the brush, the user can continue to select the existing line color, line type, line thickness, and other options in the toolbar. The line color, line type, and line thickness selected by the user in the toolbar are input by the brush control 621 configured as the target type. In a state of picking up the brush control, the user may input content based on contact with the drawing area 610, i.e., a contact trajectory of the user on the drawing area 610.

In some embodiments, each time the user inputs operation contents in the drawing area 610, the display device stores drawing operation data corresponding to the operation contents.
