Display Devices

This application is a divisional application of (application number: 202010177064.4, application date: 2020-03-13, invention name: display device).

Technical Field

The present disclosure relates to the technical field of smart televisions, and in particular to display devices.

Background Art

Smart TV devices have independent operating systems and support functional expansion. Various applications can be installed on smart TVs according to user needs, such as traditional video applications, social applications such as short videos, and reading applications such as comics and books. These applications can use the screen of smart TVs to display application images and provide smart TVs with rich media resources. At the same time, smart TVs can also interact with different terminals for data and resource sharing. For example, smart TVs can connect to mobile phones through wireless communication methods such as LAN and Bluetooth to play resources in mobile phones or directly cast the screen to display the images on mobile phones.

However, since different applications or media sources have different picture ratios, smart TVs are often used to display pictures with different ratios from traditional videos. For example, video resources shot by mobile phones and other terminals are generally vertical media with aspect ratios of 9:16, 9:18, 3:4, etc.; while the pictures provided by reading applications are vertical resources with an aspect ratio similar to that of books. The aspect ratio of the display screen of a smart TV is generally horizontal, such as 16:9. Therefore, when displaying vertical media such as short videos and comics on a smart TV, the vertical media picture cannot be displayed normally because the picture ratio does not match the display screen ratio. Generally, the vertical media picture needs to be scaled to be fully displayed, which not only wastes the display space on the screen, but also brings a bad user experience.

Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

A rotating TV is a new type of smart TV, which mainly includes a display and a rotating component. The display is fixed to a wall or a bracket through a rotating component, and the display placement angle can be adjusted through the rotating component to achieve the purpose of rotation to adapt to display images with different aspect ratios. For example, in most cases the display is placed horizontally to display video images with aspect ratios of 16:9, 18:9, etc. When the aspect ratio of the video screen is 9:16, 9:18, etc., the horizontally placed display needs to scale the screen and display black areas on both sides of the display. Therefore, the display can be placed vertically through the rotating component to adapt to video images with ratios of 9:16, 9:18, etc.

In order to facilitate users to display target media asset details pages in different horizontal and vertical screen states of the display, and to improve the user viewing experience when the display device is in different viewing states, the embodiment of the present application provides a display device, a details page display method and a computer storage medium, and the display device is such as a rotating TV.

In some other exemplary embodiments, the detector 230 may further include a light receiver for collecting ambient light intensity to adapt to changes in display parameters of the display device 200 .

In some other exemplary embodiments, the detector 230 may also include a temperature sensor, such as by sensing the ambient temperature, the display device 200 may adaptively adjust the display color temperature of the image. For example, when the temperature is high, the display device 200 may be adjusted to display a cooler color temperature of the image; when the temperature is low, the display device 200 may be adjusted to display a warmer color temperature of the image.

The external device interface 240 is a component that provides the controller 250 with control of data transmission between the display device 200 and an external device. The external device interface 240 can be connected to an external device such as a set-top box, a game device, a notebook computer, etc. in a wired/wireless manner, and can receive data such as video signals (such as moving images), audio signals (such as music), additional information (such as EPG), etc. from the external device.

Among them, the external device interface 240 may include: a high-definition multimedia interface (HDMI) terminal 241, a composite video blanking synchronization (CVBS) terminal 242, an analog or digital component terminal 243, a universal serial bus (USB) terminal 244, a component terminal (not shown in the figure), a red, green and blue (RGB) terminal (not shown in the figure), and any one or more of the like.

The controller 250 controls the operation of the display device 200 and responds to the user's operation by running various software control programs (such as an operating system and various application programs) stored in the memory 260.

As shown in FIG3 , the controller 250 includes a random access memory (RAM) 251, a read-only memory (ROM) 252, a graphics processor 253, a CPU processor 254, a communication interface 255, a communication bus 256, a rotation processor 257, and an animation processor 258. The RAM 251, the ROM 252, the graphics processor 253, the CPU processor 254, the communication interface 255, and the controller 250 are connected via the communication bus 256. The function of the rotation processor 257 will be described in detail in the subsequent embodiments.

ROM252 is used to store various system startup instructions. When a power-on signal is received, the display device 200 starts to power on, and the CPU processor 254 runs the system startup instructions in ROM252, and copies the operating system stored in the memory 260 to the RAM 251 to start running the startup operating system. After the startup of the operating system is completed, the CPU processor 254 copies various application programs in the memory 260 to the RAM 251, and then starts running the startup various application programs.

The graphics processor 253 is used to generate various graphic objects, such as icons, operation menus, and user input command display graphics. The graphics processor 253 may include an operator, which is used to perform operations by receiving various interactive instructions input by the user, and then display various objects according to display attributes; and a renderer, which is used to generate various objects based on the operator, and display the rendering results on the display 275.

The CPU processor 254 is used to execute the operating system and application instructions stored in the memory 260, and to process various applications, data and content according to the received user input instructions, so as to finally display and play various audio and video contents.

In some exemplary embodiments, the CPU processor 254 may include multiple processors. The multiple processors may include a main processor and multiple or one sub-processors. The main processor is used to perform some initialization operations of the display device 200 in the display device preload mode, and/or the operation of displaying a picture in the normal mode. The multiple or one sub-processors are used to perform an operation in the display device standby mode and other states.

The communication interface 255 may include a first interface to an nth interface, and these interfaces may be network interfaces connected to external devices via a network.

The controller 250 may control the overall operation of the display device 200. For example, in response to receiving a user input command for selecting a GUI object displayed on the display 275, the controller 250 may perform an operation related to the object selected by the user input command.

The object may be any one of the selectable objects, such as a hyperlink or an icon. The operation related to the selected object may be, for example, an operation of displaying a page, document, image, etc. connected to the hyperlink, or an operation of executing a program corresponding to the object. The user input command for selecting the GUI object may be a command inputted through various input devices (e.g., a mouse, a keyboard, a touch pad, etc.) connected to the display device 200 or a voice command corresponding to a voice spoken by the user.

The memory 260 is used to store various types of data, software programs or applications for driving and controlling the operation of the display device 200. The memory 260 may include volatile and/or non-volatile memory. The term "memory" includes the memory 260, the RAM 251 and the ROM 252 of the controller 250, or a memory card in the display device 200.

In some embodiments, the memory 260 is specifically used to store the running program that drives the controller 250 in the display device 200; store various application programs built into the display device 200 and downloaded by the user from an external device; store data such as visual effect images for configuring various GUIs provided by the display 275, various objects related to the GUI, and selectors for selecting GUI objects.

In some embodiments, the memory 260 is specifically used to store drivers and related data for the tuner-demodulator 210, the communicator 220, the detector 230, the external device interface 240, the video processor 270, the display 275, the audio processor 280, etc., such as external data received from the external device interface (e.g., audio and video data) or user data received by the user interface (e.g., key information, voice information, touch information, etc.).

In some embodiments, the memory 260 specifically stores software and/or programs for representing an operating system (OS), which may include, for example, a kernel, middleware, an application programming interface (API), and/or an application. Exemplarily, the kernel may control or manage system resources, as well as functions implemented by other programs (such as the middleware, API, or application); at the same time, the kernel may provide an interface to allow the middleware, API, or application to access the controller to control or manage system resources.

Fig. 4 exemplarily shows a block diagram of the architecture configuration of the operating system in the memory of the display device 200. The operating system architecture is composed of an application layer, a middleware layer and a kernel layer from top to bottom.

The application layer includes both built-in applications and non-system-level applications. It is responsible for direct interaction with users. The application layer can include multiple applications, such as settings applications, e-mail applications, media center applications, etc. These applications are mainly developed based on the Android system, and the development language can be Java/C++. These applications can also be implemented as Web applications, which are executed based on the WebKit engine, and can be developed and executed based on HTML5, Cascading Style Sheets (CSS) and JavaScript.

Here, HTML, the full name of which is HyperText Markup Language, is a standard markup language used to create web pages. Web pages are described by marking tags. HTML tags are used to describe text, graphics, animations, sounds, tables, links, etc. The browser will read the HTML document, interpret the content of the tags in the document, and display it in the form of a web page.

CSS, the full name of which is Cascading Style Sheets, is a computer language used to express the style of HTML files. It can be used to define style structures, such as fonts, colors, positions, etc. CSS styles can be directly stored in HTML web pages or in separate style files to control the styles in web pages.

JavaScript is a language used for web page programming. It can be inserted into HTML pages and interpreted and executed by browsers. The interactive logic of web applications is implemented through JavaScript. JavaScript can encapsulate JavaScript extension interfaces through browsers to achieve communication with the kernel layer.

The middleware layer can provide some standardized interfaces to support the operation of various environments and systems. For example, the middleware layer can be implemented as the Multimedia and Hypermedia Information Coding Experts Group (MHEG) middleware related to data broadcasting, as the DLNA middleware related to external device communication, or as the middleware that provides the browser environment for the application programs in the display device to run.

The kernel layer provides core system services, such as file management, memory management, process management, network management, system security permission management, etc. The kernel layer can be implemented as a kernel based on various operating systems, for example, a kernel based on the Linux operating system.

The kernel layer also provides communication between system software and hardware, and provides device driver services for various hardware, such as: providing display drivers for monitors, camera drivers for cameras, key drivers for remote controls, WiFi drivers for WiFi modules, audio drivers for audio output interfaces, power management drivers for power management (PM) modules, etc.

In FIG3 , the user interface 265 receives various user interactions. Specifically, it is used to send the user's input signal to the controller 250, or transmit the output signal from the controller 250 to the user. Exemplarily, the remote controller 100A can send the user's input signal such as a power switch signal, a channel selection signal, a volume adjustment signal, etc. to the user interface 265, and then the user interface 265 forwards it to the controller 250; or, the remote controller 100A can receive the output signal such as audio, video or data output from the user interface 265 after being processed by the controller 250, and display the received output signal or output the received output signal in the form of audio or vibration.

In some embodiments, the user may input a user command in a graphical user interface (GUI) displayed on the display 275, and the user interface 265 receives the user input command through the GUI. Specifically, the user interface 265 may receive a user input command for controlling the position of a selector in the GUI to select different objects or items. Among them, the "user interface" is a medium interface for interaction and information exchange between an application or an operating system and a user, which realizes the conversion between the internal form of information and the form acceptable to the user. The commonly used form of the user interface is a graphical user interface (GUI), which refers to a user interface related to computer operation displayed in a graphical manner. It can be an interface element such as an icon, a window, a control, etc. displayed on the display of an electronic device, wherein the control may include visual interface elements such as icons, controls, menus, tabs, text boxes, dialog boxes, status bars, channel bars, widgets, etc.

Alternatively, the user may input a user command by inputting a specific sound or gesture, and the user interface 265 recognizes the sound or gesture through a sensor to receive the user input command.

The video processor 270 is used to receive external video signals and perform video data processing such as decompression, decoding, scaling, noise reduction, frame rate conversion, resolution conversion, and image synthesis according to the standard codec protocol of the input signal to obtain a video signal that can be directly displayed or played on the display 275.

For example, the video processor 270 includes a demultiplexing module, a video decoding module, an image synthesis module, a frame rate conversion module, a display formatting module, and the like.

Among them, the demultiplexing module is used to demultiplex the input audio and video data stream. For example, if the input MPEG-2 stream (a compression standard for moving images and voice based on digital storage media) is input, the demultiplexing module will demultiplex it into video signals and audio signals, etc.

The video decoding module is used to process the demultiplexed video signal, including decoding and scaling processing.

The image synthesis module, such as an image synthesizer, is used to superimpose and mix the GUI signal generated by the graphics generator according to the user input or itself with the scaled video image to generate an image signal for display.

The frame rate conversion module is used to convert the frame rate of the input video, such as converting the frame rate of the input 60Hz video to a frame rate of 120Hz or 240Hz. The usual format is implemented by a frame insertion method.

The display formatting module is used to change the signal output by the frame rate conversion module into a signal that conforms to the display format of a display, such as converting the format of the signal output by the frame rate conversion module to output an RGB data signal.

The display 275 is used to receive the image signal input from the video processor 270 and display the video content, image and menu operation interface. The displayed video content may be the video content in the broadcast signal received by the tuner demodulator 210, or the video content input from the communicator 220 or the external device interface 240. The display 275 also displays the user operation interface UI generated in the display device 200 and used to control the display device 200.

Furthermore, the display 275 may include a display component for presenting images and a driving component for driving image display. Alternatively, if the display 275 is a projection display, it may also include a projection device and a projection screen.

The controller can send a control signal to the rotating component 276 to rotate the display 275 .

In one implementation, the display device 200 includes a rotating assembly 276, which can fix the display device 200 and control the display 275 to rotate so that the display 275 is in a horizontal or vertical state under the control of the controller 250. The rotating assembly 276 can be fixed to the back of the display 275, and the rotating assembly 276 is used to be fixed to the wall, and the rotating assembly 276 receives the control instruction of the controller 250 to rotate the display 275 in a vertical plane so that the display 275 is in a horizontal or vertical state.

The horizontal screen state refers to a state in which the length (width) of the display 275 in the horizontal direction is greater than the length (height) in the vertical direction when viewed from the front of the display 275; the vertical screen state refers to a state in which the length (width) of the display 275 in the horizontal direction is less than the length (height) in the vertical direction when viewed from the front of the display 275. Obviously, the vertical direction in this application refers to approximately vertical, and the horizontal direction also refers to approximately horizontal.

Driven by the rotating component 276, the display 275 can rotate 90 degrees clockwise or counterclockwise so that the display 275 is in a portrait state. In the portrait state, the display can display the user interface corresponding to the portrait state, and has an interface layout and interaction method corresponding to the portrait state. In the portrait media viewing mode, the user can watch short videos, comics and other vertical media. Similarly, since the controller 250 in the display device 200 is further connected to the server 300 in communication, it is possible to obtain the corresponding media data of the vertical screen by calling the interface of the server 300 in the portrait state.

The vertical screen state is more suitable for playing media with a vertical screen ratio of 9:16, such as short videos shot by mobile phones and other terminals. Since mobile phones and other terminal devices mostly use vertical screen ratios such as 9:16 and 9:18, when the terminal is connected to the display device 200 and the terminal screen is displayed through the display device 200, the vertical screen state can avoid excessive scaling of the screen, make full use of the display screen of the display 275, and have a better user experience.

The monitoring component 277 is used to monitor the component rotation information of the rotating component 276 and output the component rotation information to the controller.

The audio processor 280 is used to receive external audio signals, and perform decompression and decoding according to the standard codec protocol of the input signal, as well as audio data processing such as noise reduction, digital-to-analog conversion, and amplification processing to obtain an audio signal that can be played in the speaker 286.

Exemplarily, the audio processor 280 may support various audio formats, such as MPEG-2, MPEG-4, Advanced Audio Coding (AAC), High Efficiency AAC (HE-AAC), and the like.

The audio output interface 285 is used to receive the audio signal output by the audio processor 280 under the control of the controller 250. The audio output interface 285 may include a speaker 286, or an external audio output terminal 287 of a generating device for outputting to an external device, such as an earphone output terminal.

In some other exemplary embodiments, the video processor 270 may include one or more chips. The audio processor 280 may also include one or more chips.

Furthermore, in some other exemplary embodiments, the video processor 270 and the audio processor 280 may be separate chips, or may be integrated into one or more chips together with the controller 250 .

The power supply 290 is used to provide power supply support for the display device 200 with power input from an external power source under the control of the controller 250. The power supply 290 can be a built-in power supply circuit installed inside the display device 200, or a power supply installed outside the display device 200.

During the application of the display device, due to the limitation of the rotating component and its component structure, after rotating to a certain direction by a certain angle, it cannot continue to rotate in the same direction. Therefore, if the rotating component rotates in one direction each time, it will be damaged after multiple rotations.

Based on the above technical problem, the embodiment of the present application shows a display device, and the structure of the display device and the functions of each component can refer to the above embodiment. On the basis of the above embodiment, the specific operation process of the controller can refer to Figure 5. The controller is configured to execute step S101 to receive a user control instruction input by a user;

S102: In response to receiving a control instruction input by a user, reading a rotatable direction of the display

In this embodiment, the user control instruction may be a user voice, for example, the user voice is "rotate XX degrees to X", "rotate to portrait mode to X", "rotate to portrait mode", etc. In this embodiment, the user control instruction may also be operation information. Specifically, the user may output the operation information to the controller through the remote controller. For example, the operation information corresponding to the volume reduction button of the remote controller is "rotate XX degrees to X", and the user touches the volume reduction button to trigger the remote controller to output the operation information.

For a scenario where the user interacts with the controller through user voice, the user control instruction is the user voice, and accordingly, the controller 250 is configured to recognize the user control instruction;

The user sends a user control command to the controller 250 through the remote controller. Specifically, the remote controller is usually equipped with multiple buttons such as a sound adjustment button, a channel switching button, a signal source button, etc. In actual application, the corresponding relationship between each button and the user control command can be preset. When the user touches the corresponding button, the remote controller sends the user control command corresponding to the button to the controller 250.

In actual application, the user control instruction may include a control direction, such as "rotate left to portrait mode", or may not include a control direction, such as "rotate to portrait mode". The technical solution shown in the embodiment of the present application adopts different processing methods depending on whether the user control instruction includes a control direction;

(1) When the user control instruction includes the control direction:

In response to the user control instruction including a control direction, the controller 250 is configured to read the rotatable margin in the control direction;

Specifically, after receiving the user control instruction, the controller 250 first identifies whether the user information contains a control direction. If the user control instruction contains a control direction, the processing flow of the display device can refer to Figure 6A, and the controller 250 is further configured to: execute step S2A1 to read the first rotation margin, and the first rotation margin is the rotatable angle of the rotating component 276 in the control direction; (wherein, the rotatable angle of the rotating component 276 in the control direction can also be referred to as the rotatable angle of the display in the control direction).

Each rotating assembly 276 is limited by its own structure. There is a total angle that can be rotated in the clockwise direction. Generally, if the angle rotated in the clockwise direction is greater than or equal to the total angle that can be rotated in this direction, the rotating assembly 276 may be damaged. Correspondingly, there is also a total angle that can be rotated in the counterclockwise direction. Generally, if the angle rotated in the counterclockwise direction is greater than or equal to the total angle that can be rotated in this direction, the rotating assembly 276 may be damaged.

In actual application, the display device may be limited by the placement position, resulting in a total angle that can be rotated in the clockwise direction. Usually, the angle of rotation in the clockwise direction is greater than or equal to the total angle that can be rotated in this direction. In this case, the rotating component 276 may encounter obstacles in the process of driving the display 275 to rotate. Correspondingly, there is also a total angle that can be rotated in the counterclockwise direction. Usually, the angle of rotation in the counterclockwise direction is greater than or equal to the total angle that can be rotated in this direction. In this case, the rotating component 276 may encounter obstacles in the process of driving the display 275 to rotate.

In this embodiment, the first rotation margin is the rotatable angle of the rotating assembly 276 in the control direction, and the rotatable angle = the total angle that the control direction can rotate - the angle that the control direction has rotated;

The angle through which the control direction has been rotated (also referred to as a real-time rotation angle) is the result of monitoring by the monitoring component 277 .

The generation process of the first rotation margin is described in detail below with reference to a specific example.

In a feasible embodiment, the user control instruction is "rotate 90 degrees clockwise", and the corresponding "clockwise" is the control direction. When the controller 250 receives the user control instruction, it retrieves the total angle that can be rotated in the "clockwise" direction as "360 degrees"; the controller 250 retrieves the angle "0" degree that has been rotated in the "clockwise" direction; the controller 250 calculates the first rotation margin as "360 degrees".

S1B1, in response to the first rotation margin being greater than or equal to a preset angle, determining that the control direction is a rotatable direction;

The process of determining the target direction is described in detail below with reference to a specific example.

The user control instruction may include a control angle, in which case the control angle is a preset angle, such as "rotate 90 degrees clockwise" or "rotate 180 degrees clockwise". The user control instruction may not include a control angle, such as "rotate clockwise to portrait mode" or "rotate clockwise to portrait mode". The application embodiment shows that the technical solution is applicable to the rotation of the display 275. Usually, the display 275 switches between "portrait mode" and "landscape mode". Therefore, the user control instruction may not include a control angle, in which case the preset angle is 90 degrees.

In a feasible embodiment, the user control instruction is "rotate 90 degrees clockwise". The controller 250 calculates that the first rotation margin is "360 degrees" and the preset angle is 90 degrees. In response to the first rotation margin "360 degrees" being greater than or equal to the preset angle "90 degrees", the controller 250 determines that the control direction "clockwise" is a rotatable direction.

In response to the user control instruction including the control direction, the processing flow of the display device can refer to FIG. 6B , and the controller 250 is further configured as follows:

S2A1 reads a first rotation margin, where the first rotation margin is a rotatable angle of the rotating component 276 in a control direction;

In a feasible embodiment, the user control instruction is "rotate 90 degrees clockwise", and the corresponding "clockwise" is the control direction. When the controller 250 receives the user control instruction, it retrieves the total angle that can be rotated in the "clockwise" direction as "360 degrees"; the controller 250 retrieves the angle "360 degrees" that has been rotated in the "clockwise" direction; the controller 250 calculates the first rotation margin as "0 degrees".

S1B2 determines that the reverse direction of the control direction is a rotatable direction in response to the first rotation margin being smaller than a preset angle.

The method for determining the rotatable direction can be found in the above embodiments and will not be described in detail here.

In a feasible embodiment, the user control instruction is "rotate 90 degrees clockwise". The controller 250 calculates that the first rotation margin is "0 degrees" and the preset angle is 90 degrees. In response to the first rotation margin "0 degrees" being less than the preset angle "90 degrees", the controller 250 determines that the reverse direction of the control direction "counterclockwise" is the rotatable direction.

(2) When the user control instruction does not include the control direction:

After receiving the user control instruction, the controller 250 first identifies whether the user information contains a control direction. In response to the user control instruction not containing a control direction, the processing flow of the display device can refer to Figure 7A. The controller 250 is further configured to execute step S2A2 to read the second rotation margin, and the second rotation margin is the rotatable angle of the rotating component 276 in the preset direction.

In this embodiment, the second rotation margin is the rotatable angle of the rotating assembly 276 in the preset direction, and the rotatable angle = the total angle that can be rotated in the preset direction - the angle that has been rotated in the preset direction;

The angle by which the preset direction has been rotated (also referred to as a real-time rotation angle) is the result of monitoring by the monitoring component 277 .

The generation process of the second rotation margin is described in detail below with reference to a specific example.

In a feasible embodiment, the user preset information is "rotate 90 degrees", and in this embodiment, "clockwise" is the preset direction. When the controller 250 receives the user preset information, it retrieves the total angle that can be rotated in the "clockwise" direction as "360 degrees", and the controller 250 retrieves the angle that has been rotated in the "clockwise" direction as "360 degrees"; the controller 250 calculates the second rotation margin as "0 degrees".

S1B3, in response to the second rotation margin being greater than or equal to the preset angle, determining the preset direction as a rotatable direction;

In a feasible embodiment, the user control instruction is "rotate 90 degrees", and in this embodiment, "clockwise" is the preset direction. The controller 250 calculates that the second rotation margin is "0 degrees" and the preset angle is 90 degrees. In response to the second rotation margin "0 degrees" being less than the preset angle "90 degrees", the controller 250 determines that the reverse direction of the control direction "counterclockwise" is the rotatable direction.

In response to the user control instruction not including a control direction, the processing flow of the display device can refer to FIG. 7B , and the controller 250 is further configured to execute step S2A2 to read a second rotation margin, where the second rotation margin is a rotatable angle of the rotating component 276 in a preset direction.

In a feasible embodiment, the user control instruction is "rotate 90 degrees", and in this embodiment, "clockwise" is the preset direction. When the controller 250 receives the user control instruction, it retrieves the total angle that can be rotated in the "clockwise" direction as "360 degrees"; the controller 250 retrieves the angle "360 degrees" that has been rotated in the "clockwise" direction; the controller 250 calculates the second rotation margin as "0 degrees".

S1B4: In response to the second rotation margin being smaller than the preset angle, determining that the reverse direction of the preset direction is a rotatable direction.

The method for determining the rotatable direction can be found in the above embodiments and will not be described in detail here.

In a feasible embodiment, the user control instruction is "rotate 90 degrees clockwise". The controller 250 calculates that the first rotation margin is "0 degrees" and the preset angle is 90 degrees. In response to the first rotation margin "0 degrees" being less than the preset angle "90 degrees", the controller 250 determines that the reverse direction of the control direction "counterclockwise" is the rotatable direction.

S103 controls the display to rotate to a preset angle in the rotatable direction.

The specific rotation process of the display can be seen in FIGS. 8A and 8B , which are schematic diagrams showing the rotation of the display according to a preferred embodiment.

The rotating component 276 is configured to execute step S104 to drive the display to rotate a preset angle based on the control of the controller.

It can be seen from the above technical solutions that the display device shown in the embodiment of the present application includes: a display; a controller configured to: read the rotatable direction of the display in response to a control instruction input by a user; and control the display to rotate to a preset angle in the rotatable direction. Based on the present invention, the controller reads the rotatable direction of the display device each time before controlling the display to rotate. If the rotatable angle in the rotatable direction is greater than the preset angle, the display is controlled to rotate to the preset angle in the rotatable direction. The above control method can avoid damage to the display caused by excessive rotation.

It is worth noting that the implementation process of the above control method can rely on the controller, or it can rely on the conversion processor in the controller, or it can rely on an independent rotation processor established in the display device. In actual application, the display device can be configured according to actual needs.

Embodiment 2:

Furthermore, during the process of the display 275 rotating to a preset angle in a certain direction, it may encounter obstacles (such as the user's furniture) and fail to complete the rotation to the preset angle.

Please refer to FIG. 9A . The display device shown in the present application is based on the display device shown in Example 1. The controller 250 is further configured to execute step S104 to monitor the real-time rotation angle of the rotating component 276 .

The data collection process of the controller 250 is described in detail below with reference to specific examples.

The data collected by the controller 250 can be found in Table 1.

Table 1

In this embodiment, the controller 250 collects the angle increase value of the component rotation, and each angle increase value recorded by the acceleration sensor corresponds to a real-time rotation angle.

For example, in the initial state, the display 275 is in the horizontal state and the corresponding real-time rotation angle is "0 degrees";

At 0.2S, the angle increase value received from the acceleration sensor is "2 degrees", and the corresponding real-time rotation angle is "2 degrees";

The angle increase value received from the acceleration sensor at 0.4S is "2 degrees", and the corresponding real-time rotation angle is "4 degrees".

The controller 250 is further configured to: execute step S1052A to calculate the rate of change of the real-time rotation angle;

The controller 250 collects an angle increase value of "2 degrees" at 0.2S, and the corresponding real-time rotation angle is "2 degrees". The controller 250 calculates that the change rate of the real-time rotation angle in the time from 0s to 0.2s is 2/0.2=10 degrees/second. In this implementation, the preset change rate is 5 degrees/second. Based on this, it can be determined that the change rate of the real-time rotation angle in unit time in the time of 0.2s is greater than the preset change rate, and it is determined that the rotating component 276 is continuously rotating.

The controller 250 collects the angle increase value "0 degrees" at 0.4S, and the controller 250 calculates that the change rate of the real-time rotation angle in the time of 0.2-0.4S is 0/0.2=0 degrees/second. In this embodiment, the preset change rate is 5 degrees/second. Based on this, it can be determined that the change rate of the real-time rotation angle in the time of 0.2s-0.4s in 1s is less than the preset change rate, and it is determined that the rotation component 276 stops rotating in the time period of 0.2s-0.4s.

In the process of actual application, in order to reduce the amount of calculation of the controller 250, the controller 250 can calculate the rate of change over a certain period of time. In a feasible real-time, the controller 250 collects an angle increase value of "2 degrees" at 0.2s, the controller 250 receives an angle increase value of "0 degrees" sent by the acceleration sensor at 0.4s, the controller 250 receives an angle increase value of "0 degrees" sent by the acceleration sensor at 0.6s, the controller 250 receives an angle increase value of "0 degrees" sent by the acceleration sensor at 0.8s, and the controller 250 receives an angle increase value of "0 degrees" sent by the acceleration sensor at 1s. At this time, the controller 250 calculates that the real-time rotation angle has a change rate of 0.2/1=0.2 degrees/second within 0-1s, and the preset change rate in this implementation is "5 degrees/second". Based on this, it can be determined that the change rate of the real-time rotation angle within 1s is less than the preset change rate within 0-1s, and it is determined that the rotating component 276 stops rotating.

S1051B, in response to the change rate being less than a preset change rate, calculating an angle difference between the real-time rotation angle and the preset angle;

In response to the difference being greater than the preset angle difference, determining current rotation information, the current rotation information comprising: a current rotation direction and a current rotation angle, the current rotation direction being the rotatable direction, and the current rotation angle being the difference between the preset angle and the real-time rotation angle;

In actual application, the preset angle difference can be set according to demand, and the applicant does not limit the preset angle difference.

In a feasible embodiment, in the initial state, the display 275 is in the horizontal screen state and the corresponding real-time rotation angle is "0 degree"; the preset angle difference is "5 degrees", the user control instruction is "rotate 90 degrees clockwise", and the controller 250 determines that "clockwise" is the rotatable direction.

The angle increment value collected at 5.2S is "2 degrees", and the corresponding real-time rotation angle is "52 degrees";

The angle increase value collected at 5.4S is "2 degrees", and the corresponding real-time rotation angle is "54 degrees".

The angle increment value collected at 5.6S is "2 degrees", and the corresponding real-time rotation angle is "56 degrees";

The angle increase value collected at 5.8S is "2 degrees", and the corresponding real-time rotation angle is "58 degrees".

The angle increment value collected at 6S is "2 degrees", and the corresponding real-time rotation angle is "60 degrees";

The angle increment value collected at 6.2S is "0 degrees", and the corresponding real-time rotation angle is "60 degrees";

The angle increase value collected at 6.4S is "0 degrees", and the corresponding real-time rotation angle is "60 degrees".

The angle increment value collected at 6.6S is "0 degrees", and the corresponding real-time rotation angle is "60 degrees";

The angle increase value collected at 6.8S is "0 degrees", and the corresponding real-time rotation angle is "60 degrees".

The angle increment value collected at 7S is "0 degrees", and the corresponding real-time rotation angle is "60 degrees";

The controller 250 calculates the rate of change of the real-time rotation angle in the time period every 1s. The rate of change of the real-time rotation angle in the time period from the 5th to the 6th second is "(0+0+0+0+0)/1", which is less than the preset rate of change "5 degrees/second". It is determined that the rotation assembly 276 stops rotating at this time, and the real-time rotation angle at this time is "60 degrees". Accordingly, the angle difference between the real-time rotation angle "60 degrees" and the preset angle is "30 degrees".

In response to the difference value "30 degrees" being greater than the preset angle difference value "0 degrees", the current rotation information is determined, and the current rotation information includes: the current rotation direction and the current rotation angle, the current rotation direction is the rotatable direction "clockwise", and the current rotation angle is the difference value "30 degrees" between the preset angle and the real-time rotation angle.

S1051D outputs a rotation instruction carrying the current rotation information;

The rotating component 276 is further configured to execute step S106 based on the control of the rotation instruction, driving the display 275 to rotate according to the instruction of this rotation information.

It should be noted that the above monitoring (collection) process and calculation process can be completed based on the controller. In a feasible embodiment, the above calculation process can also be based on a conversion processor set in the controller. The above monitoring process can also be completed based on an independently set monitoring component 277, which can be a gyroscope, a geomagnetic sensor, an acceleration sensor, or a variety of sensors. Of course, other sensors are not excluded.

In a feasible embodiment, the monitoring component 277 may be an acceleration sensor, which collects a real-time rotation angle at every preset time interval.

Embodiment 3:

Please refer to FIG. 9B . In a feasible embodiment, the controller 250 of the display device is further configured to execute step S104 to monitor the real-time rotation angle of the rotating component 276 based on the display device shown in Embodiment 1.

The controller 250 is further configured to: execute step S1052A to calculate the rate of change of the real-time rotation angle;

The calculation process of the change rate of the real-time rotation angle can be referred to in the above embodiment and will not be described in detail here.

S1052B, in response to the change rate being less than a preset change rate, calculating an angle difference between the real-time rotation angle and the preset angle;

S1052C: In response to the difference being greater than the preset angle difference, determining current rotation information, the current rotation information including: current rotation direction and current rotation angle, the current rotation direction being the opposite of the rotatable direction, and the current rotation angle being the sum of the real-time rotation angle and the preset angle;

S1052D outputs a rotation instruction carrying the current rotation information;

S106 The rotating component 276 is further configured to drive the display 275 to rotate according to the instruction of this rotation information based on the control of the rotation instruction.

For example: In a feasible embodiment, in the initial state, the display 275 is in the horizontal screen state and the corresponding real-time rotation angle is "0 degrees"; the preset angle difference is "5 degrees", the user control instruction is "rotate 90 degrees clockwise", and the controller 250 determines that "clockwise" is the rotatable direction. The controller 250 calculates the rate of change of the real-time rotation angle of the time period in the unit time every 1s. The rate of change of the real-time rotation angle in the time period from the 5th to the 6th second is "(0+0+0+0+0)/1", which is less than the preset change rate of "5 degrees/second". It is determined that the rotating component 276 stops rotating at this time, and the real-time rotation angle at this time is "60 degrees". Correspondingly, the angle difference between the real-time rotation angle "60 degrees" and the preset angle is "30 degrees".

In response to the difference value "30 degrees" being greater than the preset angle difference value "0 degrees", the current rotation information is determined, and the current rotation information includes: the current rotation direction and the current rotation angle, the current rotation direction is the opposite "counterclockwise" of the rotatable direction, and the current rotation angle is the sum of the real-time rotation angle and the preset angle "60 degrees + 90 degrees".

8 Optionally, in response to the difference being greater than a preset angle difference, the total angle that can be rotated in that direction is modified.

Furthermore, when the display 275 is rotated 90 degrees in a certain direction, it may encounter obstacles (such as the user's furniture) on the way and fail to complete the preset angle. When this problem occurs once or N times, it can be automatically recorded in the software and the total angle that can be rotated in this direction can be modified. For example, if the display 275 cannot be rotated clockwise when in landscape mode, the total angle that can be rotated in the clockwise direction is 0. In this way, in the above step 4, it directly returns to the state that there is no rotation margin in the direction to be rotated.

Optionally, the direction of each rotation is fixed to be the opposite direction of the last rotation. For example, if the screen is rotated clockwise when it is turned to portrait mode, then the next time it is turned to landscape mode, it is rotated counterclockwise in the opposite direction.

It should be noted that the above monitoring (collection) process and calculation process can be completed based on the controller. In a feasible embodiment, the above calculation process can also be based on a conversion processor set in the controller. The above monitoring process can also be completed based on an independently set monitoring component 277, which can be a gyroscope, a geomagnetic sensor, an acceleration sensor, or a variety of sensors. Of course, other sensors are not excluded.
