Display device

Technical Field

The application relates to the technical field of rotating social televisions, in particular to a display device.

Background

The smart television has an independent operating system and supports function expansion. Various application programs can be installed in the smart television according to the needs of the user, for example, social applications such as traditional video applications and short videos, and reading applications such as cartoons and books. The applications can display application pictures by utilizing a screen of the intelligent television, and rich media resources are provided for the intelligent television. Meanwhile, the intelligent television can also perform data interaction and resource sharing with different terminals. For example, the smart television can be connected with a mobile phone through a wireless communication mode such as a local area network and bluetooth, so as to play resources in the mobile phone or directly project a screen to display a picture on the mobile phone.

However, since the picture scales corresponding to different applications or media assets from different sources are different, the smart tv is often used to display pictures with different scales from the traditional video. For example, video resources shot by a terminal such as a mobile phone are generally vertical media resources with aspect ratios of 9:16, 9:18, 3:4 and the like; and the pictures provided by the reading application are vertical resources similar to the aspect ratio of the book. The aspect ratio of the display screen of the intelligent television is generally in a transverse state of 16:9, 16:10 and the like, so when vertical media such as short videos, cartoons and the like are displayed through the intelligent television, vertical media pictures cannot be normally displayed due to the fact that the picture ratio is not matched with the display screen ratio. Generally, the vertical media asset images need to be zoomed to be displayed completely, which not only wastes the display space on the screen, but also brings bad user experience.

Detailed Description

In order to make the embodiments in the present application better understood by those skilled in the art, the embodiments in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The rotary social television is a novel intelligent television and mainly comprises a display and a rotary component. The display is connected to the support or the wall through the rotating assembly, and the display placing angle can be adjusted through the rotating assembly to achieve the purpose of rotation. Different display placement angles can accommodate animated pages of different aspect ratios, for example, in most cases the display is placed horizontally to display video frames of movies, television shows, etc. having an aspect ratio of 16: 9. When a video frame has a 9:16 aspect ratio of short video, caricature, or the like, the horizontally disposed display needs to be scaled and black areas are displayed on both sides of the display. Thus, the display can be positioned vertically by rotating the assembly to accommodate a 9:16 scaled video frame.

The applications supported by the rotary social television are numerous, so that a user can conveniently watch the television, and a starting signal source of the television can be appointed by setting a starting mode. For example, in order to obtain the viewing experience of a conventional television, a starting signal source of the television can be set as a live signal, so that the television directly enters a live state after being started. The user can set the starting signal source into any application program through the setting program. Because the postures of the display supported by different applications are different, the posture of the television at the time of starting up is adaptive to the application used as the starting-up signal source, and the picture corresponding to the application of the starting-up signal source can be normally displayed.

However, when watching television, the user can adjust the display posture of the rotary social television according to needs, and the display posture is still kept after adjustment when the television is turned off. For example, when a user watches a short video or a cartoon through a television, the user switches the screen to a vertically placed state and turns off the television in the vertically placed state. When the user starts the computer for the next time, the screen is in a vertically placed state, and if the starting signal source is set to be an application only supporting the horizontally placed state, the screen is not matched with the application of the starting signal source, and the screen cannot be correctly displayed. Accordingly, the present application provides a display device.

In order to facilitate a user to display a target media asset detail page in different horizontal and vertical screen states of a display and to facilitate improvement of user viewing experience of a display device in different viewing states, embodiments of the present application provide a display device, a detail page display method, and a computer storage medium, where the display device is, for example, a rotating television.

In FIG. 3, user interface 265, receives various user interactions. Specifically, it is used to transmit an input signal of a user to the controller 250 or transmit an output signal from the controller 250 to the user. For example, the remote controller 100A may transmit an input signal, such as a power switch signal, a channel selection signal, a volume adjustment signal, etc., input by the user to the user interface 265, and then the input signal is transferred to the controller 250 through the user interface 265; alternatively, the remote controller 100A may receive an output signal such as audio, video, or data output from the user interface 265 via the controller 250, and display the received output signal or output the received output signal in audio or vibration form.

In some embodiments, a user may enter user commands on a Graphical User Interface (GUI) displayed on the display 275, and the user interface 265 receives the user input commands through the GUI. Specifically, the user interface 265 may receive user input commands for controlling the position of a selector in the GUI to select different objects or items. Among these, "user interfaces" are media interfaces for interaction and information exchange between an application or operating system and a user, which enable the 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 (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 control, a menu, a tab, a text box, a dialog box, a status bar, a channel bar, a Widget, etc.

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

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

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

The demultiplexing module is configured to demultiplex an input audio/video data stream, where, for example, an input MPEG-2 stream (based on a compression standard of a digital storage media moving image and voice), the demultiplexing module demultiplexes the input audio/video data stream into a video signal and an audio signal.

And the video decoding module is used for processing the video signal after demultiplexing, including decoding, scaling and the like.

And the image synthesis module is used for carrying out superposition mixing processing on the GUI signal input by the user or generated by the user and the video image after the zooming processing by the graphic generator so as to generate an image signal for display.

The frame rate conversion module is configured to convert a frame rate of an input video, for example, convert a frame rate of an input 60Hz video into a frame rate of 120Hz or 240Hz, where a common format is implemented by using, for example, an interpolation frame method.

A display format module for converting the signal output by the frame rate conversion module into a signal conforming to a display format such as the display 275, for example, converting the format of the signal output by the frame rate conversion module to output RGB data signals.

A display 275 for receiving the image signal from the video processor 270 and displaying the video content, the image and the menu manipulation interface. The display video content may be from the video content in the broadcast signal received by the tuner-demodulator 210, or from the video content input by the communicator 220 or the external device interface 240. The display 275, while displaying a user manipulation interface UI generated in the display apparatus 200 and used to control the display apparatus 200.

And, the display 275 may include a display screen assembly for presenting a picture and a driving assembly for driving the display of an image. Alternatively, a projection device and projection screen may be included, provided that the display 275 is a projection display 275.

Rotating assembly 276, controller 250 may issue a control signal to cause rotating assembly 276 to rotate display 275.

The audio processor 280 is configured to receive an external audio signal, decompress and decode the received audio signal according to a standard codec protocol of the input signal, and perform audio data processing such as noise reduction, digital-to-analog conversion, and amplification processing to obtain an audio signal that can be played by the speaker 286.

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

In other exemplary embodiments, video processor 270 may comprise one or more chips. Audio processor 280 may also comprise one or more chips.

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

And a power supply 290 for supplying power supply support to the display apparatus 200 from the power input from the external power source under the control of the controller 250. The power supply 290 may be a built-in power supply circuit installed inside the display apparatus 200 or may be a power supply installed outside the display apparatus 200.

Because the display device 200 provided herein includes the display 275 and the rotating assembly 276, the rotating assembly 276 can rotate the display 275 to enable the display 275 to be in different display orientations. Thus, in one implementation, the display direction may include a landscape display direction and a portrait display direction. Wherein the landscape display direction is a display direction in which the length (width) of the display 275 in the horizontal direction is greater than the length (height) of the display 275 in the vertical direction when viewed from the front of the display 275; the vertical screen display direction is a display direction in which the length (width) of the display 275 in the horizontal direction is smaller than the length (height) of the display 275 in the vertical direction when viewed from the front of the display 275.

Obviously, depending on the installation/placement position of the display device 200, the vertical direction is referred to as substantially vertical in the present application, and the horizontal direction is also referred to as substantially horizontal. The horizontal display direction is mainly used for displaying horizontal media such as a tv drama and a movie as shown in fig. 5A. The mode of operation of the display 275 in the landscape orientation may be referred to as the landscape viewing mode and the mode of operation of the display 275 in the portrait orientation may be referred to as the portrait viewing mode. The controller 250 in the display device 200 is further communicatively connected to the server 300 for invoking an interface of the server 300 to obtain corresponding data. The display 275 in the display device 200 can be driven to rotate by the rotation assembly 276 and used to display a user interface. In practical applications, a user may control a play mode, play contents, and the like of the display apparatus 200 through the control device 100, wherein the play mode includes a landscape viewing mode and a portrait viewing mode.

The vertical screen display direction is mainly used for displaying vertical media such as short videos and cartoons, as shown in fig. 5B. In the vertical screen display direction, the display 275 may display the user interface corresponding to the vertical screen display direction and have an interface layout and an interaction mode corresponding to the vertical screen display direction. In the vertical screen media asset watching mode, a user can watch vertical screen media assets such as short videos and cartoons. Similarly, since the controller 250 in the display device 200 is further in communication connection with the server 300, the media asset data corresponding to the vertical screen can be acquired by calling the interface of the server 300 when the vertical screen displays the direction.

The vertical screen display direction is more suitable for playing the picture with the ratio of 9:16, etc., such as short videos shot by a terminal such as a mobile phone, etc. Because terminal equipment such as cell-phones adopts 9 more: 16,9: 18, and the like, when the terminal accesses the display device 200 and displays a terminal screen through the display device 200, the vertical screen display direction can avoid excessive zooming of the screen, the application page of the display 275 is fully utilized, and better user experience is achieved.

It should be noted that the horizontal screen display direction and the vertical screen display direction are only two different display directions of the display 275, and do not limit the displayed content, for example, vertical media such as short videos and cartoons can still be displayed in the horizontal screen display direction; horizontal media such as TV dramas and movies can still be displayed in the vertical screen display direction, and only the display windows which are not matched with each other need to be compressed and adjusted in the display direction.

When the user uses the display device 200, the display direction of the display 275 is adjusted according to the viewing needs of the user. For example, after a rotation command is issued by controlling a rotation key on the apparatus 100, or selecting a rotation option on a UI interface, or inputting a "rotation" related voice through a voice system, the controller 250 controls the rotation component 276 to rotate according to the rotation command to drive the display 275 to rotate. For example, when the user wants to watch a short video through the display device 200, the user can input a rotation instruction in one of the above manners to rotate the display 275 in the landscape display direction counterclockwise by 90 degrees to the portrait display direction, so as to adapt to the picture scale of a vertical application such as a short video.

There is a case where a user watches a video using the display apparatus shown in the present application, but a display direction supported by the video is not identical to a current display direction of the display 275, resulting in a problem of wasting screen resources. Specifically, referring to fig. 6, fig. 6 is a schematic diagram of a video frame of the display 275 according to a possible embodiment, and it can be seen in the interface 1 that a display direction of the video support is a vertical-screen display direction, but a current display direction of the display 275 is a horizontal-screen display direction, which results in a waste of screen resources corresponding to the area a and the area B of the display 275.

Typically, the user will choose to control the rotation of the display 275 so that the display direction of the rotated display 275 is consistent with the display direction supported by the video, and particularly, referring to interface 2 in fig. 6, it can be seen that the screen resources are fully utilized.

In order to improve the experience of the user, in the process of rotating the display 275, the video frame of the currently played video needs to be controlled to rotate, and the rotation direction of the video frame is opposite to the rotation direction of the display 275, so as to ensure that the video frame watched by the user is always in a still state, specifically, refer to fig. 7A and 7B, where fig. 7A and 7B are schematic diagrams of changes of the video frame in the process of rotating the display 275. It can be seen that, during the rotation of the display 275, the rotation direction of the video frame is always opposite to the rotation direction of the display 275, so that the video interface viewed by the user is always in a static state. Generally, the controller 250 of the display apparatus draws based on a rotation angle of the display 275 during drawing of the video picture, for example, the controller 250 reads that the display 275 rotates clockwise by 3 degrees, and correspondingly controls the video picture to rotate counterclockwise by 3 degrees during drawing of the video picture.

A chain motor (also referred to herein as a rotation assembly 276) is currently used to rotate the display 275. The rotating component 276 is provided with a limit switch, and when the rotating component 276 drives the display 275 to rotate by 90 degrees, the rotating component will collide with the limit switch, so that the rotation angle of the display 275 is greatly changed, which can be specifically referred to fig. 8A and 8B. Fig. 8A is a graph of rotation angle of the display 275 versus rotation time during the rotation of the display 275 from the portrait screen state to the landscape screen state by the rotating assembly 276. At time Ti, rotating assembly 276 strikes a limit switch and the corresponding angle of rotation of display 275 fluctuates significantly. Fig. 8B is a graph of rotation angle of the display 275 versus rotation time during the rotation of the display 275 from the landscape state to the portrait state by the rotating assembly 276. At time Ti, rotating assembly 276 strikes a limit switch and the corresponding angle of rotation of display 275 fluctuates significantly.

When the rotation angle of the video interface is drawn based on the rotation angle of the display 275, the video interface greatly shakes when the rotating component 276 hits the limit switch, and specifically, as shown in fig. 7A and 7B, the frame 11 and the frame 12 obviously shake.

In order to solve the above technical problem, an embodiment of the present application illustrates a display device, and a work flow of the display device may refer to fig. 9. Specifically, the display device shown in the embodiment of the present application includes: a display 275, a rotating assembly 276, and a controller 250, wherein:

a display 275 for presenting video pictures.

A rotating assembly 276, wherein the rotating assembly 276 is connected with the display 275 and is configured to drive the display 275 to rotate;

a controller 250 configured to perform the steps of:

s101, in response to an instruction to play a video, controls the display 275 to play the video;

the controller 250 may receive an instruction for playing a video input by a user through a user interface. For example: the user may initiate a radio function of controller 250 based on the wake-up word and then interact with controller 250. A specific implementation may be where the user speaks a wake-up word prior to interacting with controller 250, at which time the radio of controller 250 can be initiated. Accordingly, the controller 250 may receive an instruction input by a user through the user interface.

The controller 250 may also be responsive to user initiated instructions for playing the video via a remote control. For example: if the user wants to watch the video, the user presses a corresponding key on the remote controller, and at this time, the remote controller sends an instruction for playing the video to the controller 250.

The embodiments of the present application merely show two sending manners of the instruction for playing the video by way of example, and in the process of practical application, the sending manner of the instruction for playing the video is not limited to the two manners.

S102 reads a first display direction and a second display direction, where the first display direction is a display direction supported by a currently played video, and the second display direction is a current display direction of the display 275;

in this embodiment, in response to the playing of the video, the controller 250 may obtain whether the first display direction is the landscape display direction or the portrait display direction, and whether the second display direction is the landscape display direction or the portrait display direction by executing the relevant program. There are various ways of determining the first/second presentation directions.

For example, the controller 250 may determine the first presentation direction by reading a resolution of the video. Wherein the resolution of the video includes the width and height of the video. If the width is larger than the height, the display direction of the video is a transverse screen display direction; and if the width is smaller than the height, the display direction of the video is the vertical screen display direction.

Specifically, after completing the action of loading the video, the attribute value of the video is also stored in the local memory of the controller 250, and at this time, the controller 250 may determine the display direction of the video by calling the resolution in the attribute value. The resolution describes the number of pixels that the video contains in both the "horizontal" and "vertical" dimensions. For example, a 1920 × 1080 video is composed of 1920 pixels in the horizontal direction and 1080 pixels in the vertical direction (2,073,600 pixels in total). And based on the resolution, whether the video is a horizontal screen display video or a vertical screen display video can be obtained.

In a possible embodiment, the resolution of the video loaded by the controller 250 is 320 × 240, and the controller 250 determines that the video is a landscape display video, and the corresponding first display direction is a landscape display direction. In another possible embodiment, the resolution of the loaded video is adjusted to 768 × 1024 by the controller 250, and the controller 250 determines that the video is the vertical-screen display video, and accordingly, the first display direction is the horizontal-screen display direction.

For another example, to add a direction identifier to the configuration information, the controller 250 may obtain the configuration information of the video being played through the application; then, it is determined whether the first display direction is a landscape display direction or a portrait display direction based on the configuration information.

Specifically, the controller 250 is further configured to: reading a direction identifier; if the display direction identifier is a first direction identifier, the display direction supported by the video is a horizontal screen display direction; and if the display direction identifier is a second direction identifier, the display direction supported by the video is a vertical screen display direction. In the practical application process, the first identification value and the second identification value may be set according to requirements, and the applicant does not make much limitation herein. An identification value may be added to the configuration information: and com, H/V/HV, wherein H represents that the video only supports the horizontal screen display direction, V represents that the video only supports the vertical screen, and HV represents that the video simultaneously supports the horizontal screen display direction and the vertical screen display direction.

In a possible embodiment, controller 250 retrieves the orientation of the video as: and com, H, the controller 250 determines the display direction of the video support as the landscape display direction. In another possible embodiment, the controller 250 reads the orientation identification of the video: and com, V, the controller 250 determines the first display direction as the vertical screen display direction.

The current presentation direction (second presentation direction) of the display 275 may be monitored by a sensor built into the display device 200. For example, a gyroscope, a gravitational acceleration sensor, or the like is provided on the display 275 of the display device 200, and attitude data of the display 275 with respect to the direction of gravity can be determined by measuring angular acceleration or the direction of gravity. The monitored attitude data is then compared with the attitude data in the horizontal screen display direction and the vertical screen display direction, respectively, to determine the display direction in which the display 275 is currently located.

For another example, a grating angle sensor, a magnetic field angle sensor, a sliding resistance angle sensor, or the like may be provided on the rotating member 276, and the display direction in which the display 275 is currently located may be determined by measuring the angle of rotation of the rotating member 276 and comparing the angle with the angle in the landscape display direction and the portrait display direction, respectively.

The embodiment of the application is only an exemplary determination method for showing several first/second display directions, and in the process of practical application, the determination method for the first/second display directions is not limited to the above several methods.

S103, if the first display direction is not consistent with the second display direction, controlling the rotating component 276 to rotate the display 275, so that the display direction of the rotated display 275 is consistent with the first display direction;

in the actual display adapting process, if the first display direction is not consistent with the second display direction, the rotating assembly 276 is controlled to drive the display 275 to rotate, so that the display direction of the rotated display 275 is consistent with the first display direction.

For example, if it is detected by the angle sensor that the current rotation angle of the display 275 is 90 degrees, it may be determined that the display direction of the display 275 is the vertical display direction, and when the first display direction is the horizontal display direction, the display 275 may be rotated, so that the display direction of the rotated display 275 is the vertical display direction.

For another example, if it is detected by the angle sensor that the current rotation angle of the display 275 is 90 degrees, it may be determined that the display direction of the display 275 is the landscape display direction, and when the first display direction is the portrait display direction, the display 275 may be rotated, so that the display direction of the rotated display 275 is the landscape display direction.

S104, responding to the display 275 starting to rotate, recording the rotation time, wherein the rotation time is used for recording the time length of the rotation of the display 275;

in this embodiment, the controller 250 records the rotation time in response to the display 275 starting to rotate. There are various ways of determining the direction in which the display 275 will begin to rotate.

For example: referring now to fig. 10, fig. 10 is a flowchart illustrating operation of the controller 250 according to one possible embodiment, the controller 250 being further configured to perform the steps of:

s1041 acquiring a first rotational speed, the first rotational speed being used to record a rotational speed of the display 275;

a sensor may be provided on the controller 250 for monitoring the first rotational speed of the display 275 in real time. Typically the first rotational speed is 0, i.e. the display 275 is in a stationary state.

S1042 if the first rotation speed is greater than a preset rotation speed, the display 275 starts to rotate;

the preset rotation speed can be set according to requirements during practical application, and in a feasible embodiment, the preset rotation speed can be 0.01 degrees/ms. The controller 250 collects a first rotation speed every 20ms, and when the collected first rotation speed is greater than 0.01 degree/ms, the controller 250 starts recording the rotation time. The corresponding actual recording mode may be that, when the acquired first rotation speed is greater than 0.01 degrees/ms, the corresponding time is the start 0 of the rotation time.

S1043 if the first rotation speed is less than a preset rotation speed, the display 275 stops rotating.

The first rotation rate continues to be greater than the preset rotation rate during rotation of the display 275, and the first rotation rate is less than the preset rotation rate when the display 275 stops rotating.

In practice, the display 275 may be rotated by an external force, and the first rotation speed recorded by the controller 250 may be greater than the preset rotation speed. In order to avoid the above problem, in the present embodiment, the controller 250 may start recording the rotation time when the first rotation speed acquired n times in succession is greater than the preset rotation speed.

S105, generating a predicted angle according to the rotation time and a prestored rotation speed;

the rotation speed generation process of the present application can refer to fig. 11, wherein the controller 250 is further configured to perform the following steps:

s1051 respectively records the time T required by N times of rotating the display 275 by a first preset angle_θ,N；

The first preset angle can be set according to requirements during practical application, and in a feasible embodiment, the first preset angle is set to be 90 degrees.

First rotation: the controller 250 controls the display to rotate while recording the time T required for the display 275 to rotate 90 degrees_90,1；

And (3) second rotation: the controller 250 controls the display to rotate while recording the time T required for the display 275 to rotate 90 degrees_90,2；

And (3) third rotation: the controller 250 controls the display to rotate while recording the time T required for the display 275 to rotate 90 degrees_90,3；

Fourth rotation: the controller 250 controls the display to rotate while recording the time T required for the display 275 to rotate 90 degrees_90,4；

……

And (3) rotation for the Nth time: the controller 250 controls the display to rotate while recording the time T required for the display 275 to rotate 90 degrees_90,N。

S1052 counting the probability of occurrence at each time;

controller 250 tallies T_θ,1，T_θ,2……T_θ,NThe probability of occurrence.

FIG. 12 shows T according to a possible embodiment_θ,N-P, wherein the abscissa denotes T_θ,NI.e., the time required for the display 275 to rotate theta, P is T_θ,NThe probability of occurrence.

S1053, screening out the time with the probability greater than the preset probability as the target time;

the preset probability can be set according to requirements, wherein the higher the value of the preset probability is, the more accurate the corresponding calculation result is.

With continued reference to FIG. 12, any time between Ti and Tj may be used as the target time.

S1054, calculating the rotating speed according to the first preset angle and the target time;

the rotational speed can be calculated according to the following formula:

wherein V is a rotation speed, theta is a first preset angle, and T_θ,NIs the target time.

In a possible embodiment, θ is 30 degrees, calculated according to the method described above:

in a possible embodiment, θ is 90 degrees, calculated according to the method described above:

s1055 stores the rotation speed.

S106, drawing the video picture based on the prediction angle.

Specifically, the process of drawing the video picture may be as follows: the control of the rotating assembly 276 rotates the display 275 in a first direction; the controller 250 is further configured to: and controlling the video picture to rotate by a prediction angle according to a second direction so as to keep the video picture relatively still, wherein the first direction and the second direction are associated.

There are various ways to render the video based on the prediction angle;

for example: in a possible embodiment, the pre-stored rotation angle is 0.01 degrees/ms. When the controller 250 controls the rotating component 276 to drive the display 275 to rotate clockwise, the controller 250 calculates the prediction angle to be 0.2 degrees in 20ms, and the controller 250 configures a video picture to initialize OpenGL, configures an OpenGL environment, loads a video resource, and sets a video parameter. Starting the content of the video pictures, each picture model angle is rotated by 0.2 degrees counterclockwise, and the angle can change along with the change of the prediction angle in the subsequent configuration process. To keep the video page rotating, it always rotates around the center of the display 275. For example, the display 275 has a size W × H and the corresponding video frame is rotated around the (W/2, H/2) point.

For example: in a possible embodiment, the pre-stored rotation angle is 0.01 degrees/ms. When the controller 250 controls the rotating component 276 to drive the display 275 to rotate clockwise, the controller 250 calculates the prediction angle to be 0.2 degrees in 20ms, and the controller 250 configures a video picture to initialize OpenGL, configures an OpenGL environment, loads a video resource, and sets a video parameter. Starting the content of the video pictures, each picture model angle is clockwise rotated by-0.2 degrees, and the angle can change along with the change of the prediction angle in the subsequent configuration process. To keep the video page rotating, it always rotates around the center of the display 275. For example, the display 275 has a size W × H and the corresponding video frame is rotated around the (W/2, H/2) point.

The following describes in detail the operation process of the display device shown in the embodiment of the present application with reference to specific examples:

fig. 13A is a diagram illustrating a change of a video picture during rotation of the display 275 according to a possible embodiment. In the initial state, the current display orientation of the display 275 is the landscape display orientation. The user sends an instruction for playing the video to the controller 250, and the controller 250 controls the display device to display the video, at this time, the video frame can refer to the frame 31. The controller 250 determines that the display direction supported by the video is the vertical screen display direction by reading the resolution of the video. The current display direction of the display 275 is not consistent with the display direction supported by the currently played video, and the controller 250 controls the rotating assembly 276 to drive the display 275 to rotate clockwise, so that the display 275 rotates from the landscape state to the portrait state; in response to the display 275 starting to rotate, the controller 250 records the time of the rotation.

In the embodiment, the video picture rotates at a constant speed according to the rotation speed of 0.01 degrees/ms, the video picture changes smoothly in the process, and the user experience is better.

Fig. 13B is a diagram illustrating a change of a video picture during rotation of the display 275 according to another possible embodiment. In the initial state, the current display orientation of the display 275 is the vertical screen display orientation. The user sends an instruction for playing the video to the controller 250, and the controller 250 controls the display device to display the video, at this time, the video frame can refer to the interface 41. The controller 250 determines that the display direction supported by the video is the landscape display direction by reading the direction identifier of the video. The current display direction of the display 275 is not consistent with the display direction supported by the currently playing video, and the controller 250 controls the rotating component 276 to rotate the display 275 clockwise, so that the display 275 rotates from the portrait screen state to the landscape screen state. In response to the display 275 starting to rotate, the controller 250 records the time of the rotation. The controller 250 generates a predicted angle based on the rotation time and a rotation speed (0.01 degree/ms) stored in advance; and controlling the content of the video picture to rotate counterclockwise by the prediction angle in each video picture drawing process, wherein the video picture can refer to a picture 42, a picture 43, a picture 44 and a picture 45 in the rotation process. In the embodiment, the video picture rotates at a constant speed according to the rotation speed of 0.01 degrees/ms, the video picture changes smoothly in the process, and the user experience is better.

It can be seen that the present embodiment illustrates a display device including a display 275, a rotating assembly 276, and a controller 250. When the controller 250 receives an instruction for playing a video, the controller 250 controls the display 275 to play the video, and the controller 250 reads the first display direction and the second display direction at the same time; if the first display orientation is not consistent with the second display orientation, the controller 250 controls the rotating assembly 276 to rotate the display 275. When the display 275 starts to rotate, the controller 250 records the rotation time. The controller 250 calculates a prediction angle according to the rotation time and a pre-stored rotation speed each time a video picture is drawn; the controller 250 renders the video picture based on the predicted angle. In the rotation process of the display device 275 shown in the embodiment of the present application, the predicted rotation angle is calculated based on the rotation time and the rotation speed, the predicted angle is not affected by the actual rotation angle of the display 275, and even in the case where the display 275 greatly shakes due to touching the limit switch during the rotation process, the controller 250 can obtain an appropriate predicted angle based on the rotation time and the rotation speed at that time. According to the method and the device, the prediction angle is uniformly increased along with the increase of time, so that the video picture configured based on the prediction angle rotates at a constant speed along with the increase of time, the video picture changes smoothly in the process, and the user experience is better.

In the implementation shown in the embodiment of the present application, the videos include a cable video and a network video, where the network video includes: video pictures and graphic layer pictures covering the upper layer of the video pictures. The graphic layer picture is also referred to as OSD (on screen display) in the embodiment of the present application, and the graphic layer picture is displayed in a fixed or non-fixed manner. For example: the graphic layer picture may be a picture in which various notifications and the like can be superimposed using characters while a video program is being played. When a user needs to know certain information, the user calls a graphic layer picture corresponding to the information, and the graphic layer picture is cancelled after a period of time. For example: the user wants to know the volume of the currently played video, and the user calls a graphic layer picture corresponding to the volume through voice or a remote controller. The display 275 displays the graphic layer picture corresponding to the volume, and the graphic layer picture corresponding to the volume is canceled after 20 seconds. The graphics layer picture is only displayed on the display 275 when called by the user through voice or a remote control. Generally, the display 275 does not display the graphic layer screen during the rotation of the display 275, and therefore, the appearance of the graphic layer screen during the rotation of the display 275 does not affect the experience of the user.

In order to reduce the data processing amount of the controller 250, in the embodiment shown in the present application, before the display 275 rotates or when the display 275 rotates, if the auto-rotation control symbol of the graphics layer picture is in the on state, the state of the auto-rotation control symbol is adjusted to the off state, so that the controller 250 does not need to draw the graphics layer pictures of different rotation angles in real time during the rotation of the display 275.
