Technical field

This application relates to the technical field of rotating social television, and in particular to a display device.

Background technique

Smart TV has an independent operating system and supports function expansion. Various applications can be installed in the smart TV according to user needs, for example, traditional video applications, social applications such as short videos, and reading applications such as comics and books. These applications can use the screen of the smart TV to display application images, and provide rich media resources for the smart TV. At the same time, smart TVs can also exchange data and share resources with different terminals. For example, a smart TV can be connected to a mobile phone through wireless communication methods such as local area network, Bluetooth, etc., so as to play resources in the mobile phone or directly cast a screen to display the screen on the mobile phone.

However, because different applications or media assets from different sources correspond to different picture ratios, smart TVs are often used to display pictures with different ratios from traditional video. For example, video resources captured by mobile phones and other terminals are generally vertical media assets with aspect ratios of 9:16, 9:18, 3:4, etc.; while the images provided by reading applications are similar to the aspect ratio of books Vertical resources. The aspect ratio of the smart TV display screen is generally 16:9, 16:10 and other horizontal states. Therefore, when displaying short videos, comics and other vertical media assets through the smart TV, the screen ratio does not match the display screen ratio and cannot be normal. Display the vertical media assets screen. Generally, it is necessary to zoom the vertical media image to display it completely, which not only wastes the display space on the screen, but also brings a bad user experience.

Detailed ways

In order to enable those skilled in the art to better understand the embodiments of this application, the following will clearly and completely describe the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described The embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work should fall within the protection scope of this application.

Rotating social TV is a new type of smart TV, which mainly includes a display and rotating components. Among them, the display is connected to the bracket or wall through a rotating component, and the placement angle of the display can be adjusted by the rotating component to achieve the purpose of rotation. Different monitor placement angles can adapt to animated pages with different aspect ratios. For example, in most cases, the monitor is placed horizontally to display video images such as movies and TV shows with an aspect ratio of 16:9. When the aspect ratio of the video screen is 9:16 for short videos, comics, etc., the horizontally placed monitor needs to zoom in and out of the screen, and black areas are displayed on both sides of the monitor. Therefore, the display can be placed vertically by rotating the component to adapt to the 9:16 ratio video picture.

There are many applications supported by Rotating Social TV. In order to make it easier for users to watch, you can specify the start-up signal source of the TV by setting the start-up method. For example, in order to obtain the movie-watching experience of a traditional TV, the start-up signal source of the TV can be set to a live broadcast signal, so that the TV directly enters the live broadcast state after being turned on. The user can set the power-on signal source to any application through the setting program. Because different applications support different display postures, the posture of the TV when it is turned on must be adapted to the application as the power-on signal source, so that the screen corresponding to the power-on signal source application can be displayed normally.

However, when the user is watching TV, he will adjust the posture of the rotating social TV’s display as needed, and keep it in the adjusted posture when it is turned off. For example, when a user watches a short video or cartoon on a TV, he switches the screen to a vertical placement state, and shuts down the device in the vertical placement state. Then when the user turns on the next time, the screen posture is in the vertical placement state. If the startup signal source is set to an application that only supports the horizontal placement state, the screen posture does not match the startup signal source application and cannot be displayed correctly. Therefore, this application provides a display device.

In order to facilitate the user to display the target media asset details page in different horizontal and vertical screen states of the display, and to improve the user viewing experience of the 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 , Display devices such as rotating TVs. It should be noted that the method provided in this embodiment is not only applicable to rotating TVs, but also applicable to other display devices, such as computers and tablet computers.

In practical applications, the rotating assembly 276 may include, but is not limited to, one or more of the aforementioned components.

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 consists of the application layer, the middleware layer, and the kernel layer from top to bottom.

For the specific configuration introduction of the display device 200, please refer to the priority document of the Chinese patent application filed with the Chinese Patent Office on May 7, 2020, with the application date of 202010377569.5, with the application name of "a display device".

Since the display device 200 provided in the present application includes a display 275 and a rotating component 276, the rotating component 276 can drive the display 275 to rotate, so that the display 275 is in different display directions. Therefore, in an implementation manner, the display direction may include a horizontal screen display direction and a vertical screen display direction. Wherein, the horizontal display direction refers to the display direction in which the length (width) in the horizontal direction of the display 275 is greater than the length (height) in the vertical direction when viewed from the front of the display 275; the vertical display direction It refers to the display direction in which the length (width) in the horizontal direction of the display 275 is smaller than the length (height) in the vertical direction when viewed from the front of the display 275.

Obviously, affected by the installation/placement position of the display device 200, the vertical direction in the present application refers to substantially vertical, and the horizontal direction also refers to substantially horizontal. The horizontal display direction is mainly used to display horizontal media assets such as TV series and movies, as shown in Figure 5A. The operation mode when the display 275 is in the horizontal display orientation may be referred to as the horizontal media viewing mode, and the operation mode when the display 275 is in the vertical display orientation may be referred to as the vertical media viewing mode. The controller 250 in the display device 200 is further connected to the server 300 in communication, and is used to call the interface of the server 300 to obtain corresponding data. The display 275 in the display device 200 can be driven to rotate by the rotating component 276 and used to display a user interface. In practical applications, the user can control the play mode, play content, etc. of the display device 200 through the control device 100, where the play mode includes a horizontal screen media viewing mode and a vertical screen media viewing mode.

The vertical screen display direction is mainly used to display vertical media assets such as short videos and comics, as shown in FIG. 5B. In the portrait display direction, the display 275 can display a user interface corresponding to the portrait display direction, and has an interface layout and interaction mode corresponding to the portrait display direction. In the vertical screen media asset viewing mode, users can watch short videos, comics and other vertical screen media assets. In the same way, since the controller 250 in the display device 200 is further connected to the server 300 in communication, it is possible to obtain the media data corresponding to the vertical screen by calling the interface of the server 300 when the display orientation is displayed in the vertical screen.

The vertical screen display direction is more suitable for playing media assets with a vertical screen ratio of 9:16, for example, short videos shot through terminals such as mobile phones. Since terminal devices such as mobile phones mostly adopt 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 display direction can avoid the transitional scaling of the screen. , Make full use of the application page of the display 275, and have a better user experience.

It should be noted that the above-mentioned horizontal display direction and vertical display direction are only two different display directions of the display 275, and do not limit the displayed content. For example, short videos, cartoons, etc. can still be displayed in the horizontal display direction. Vertical media assets; horizontal media assets such as TV series and movies can still be displayed in the vertical display direction, but the inconsistent display windows 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 user's viewing needs. For example, you can control the rotation key on the device 100, or select the rotation option on the UI interface, or input the "rotation" related voice through the voice system to issue a rotation instruction, and the controller 250 will control the rotation component 276 to rotate according to the rotation instruction. To drive the display 275 to rotate. For example, when a user wants to watch a short video through the display device 200, he can input a rotation instruction in one of the above-mentioned ways to rotate the display 275 in the horizontal display orientation 90 degrees counterclockwise to the vertical display orientation, so as to adapt to the short video, etc. The aspect ratio of the vertical application.

There is a situation where the user uses the display device shown in this application to watch a video, but the supported display direction of the video is inconsistent with the current display direction of the display 275, resulting in a problem of wasting screen resources. For details, please refer to 6. FIG. 6 is a schematic diagram of the video screen of the display 275 according to a feasible embodiment. It can be seen from the interface 1 that the display direction supported by the video is the vertical display direction, but the current display direction of the display 275 It is the horizontal display orientation, which leads to a waste of screen resources corresponding to area A and area B of the display 275.

Generally, 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. For details, refer to interface 2 in FIG. 6 to show that the screen resources are fully utilized.

In order to enhance the user’s sense of experience, during the rotation of the display 275, it is necessary to control the rotation of the video picture of the currently playing video. The rotation direction of the video picture is opposite to the rotation direction of the display 275 to ensure that the user is watching the video picture in a static state. Generally, the controller 250 of the display device draws the video image based on the rotation angle of the display 275 during the process of drawing the video. Control the video screen to rotate 3 degrees counterclockwise.

Currently, a chain motor (also referred to as a rotating assembly 276 in this application) is used to drive the display 275 to rotate. Of course, it is not limited to a chain motor, and can also be any other component that can drive rotation. The rotation component 276 is provided with a limit switch. When the rotation component 276 drives the display 275 to rotate by 90 degrees, it will collide with the limit switch, causing a large change in the rotation angle of the display 275. For details, please refer to FIGS. 7A and 7B. FIG. 7A shows the relationship curve between the rotation angle of the display 275 and the rotation time when the rotation component 276 drives the display 275 to rotate from the vertical screen state to the horizontal screen state. When the time is Ti, the rotating component 276 hits the limit switch, and the corresponding rotation angle of the display 275 fluctuates greatly. FIG. 7B shows the relationship curve between the rotation angle of the display 275 and the rotation time when the rotation component 276 drives the display 275 to rotate from the horizontal screen state to the vertical screen state. When the time is Ti, the rotating component 276 hits the limit switch, and the corresponding rotation angle of the display 275 fluctuates greatly.

When the video screen is drawn in the above manner, since the rotation angle of the video interface is drawn based on the rotation angle of the display 275, when the rotation component 276 hits the limit switch, the video interface shakes greatly.

In order to solve the above technical problems, the embodiment of the present application shows a display device. For the operation flow of the display device, refer to FIG. 8. Specifically, the display device shown in the embodiment of the present application includes: a display 275, a rotating assembly 276, and a controller 250, where:

The display 275 is used to display video images.

A rotating component 276 connected to the display 275 and configured to drive the display 275 to rotate;

The controller 250 is configured to perform the following steps:

S101 controls the display 275 to play the video in response to the instruction for playing 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 can activate the radio function of the controller 250 based on the wake-up word, and then interact with the controller 250. The specific implementation process may be that the user speaks a wake-up word before interacting with the controller 250. At this time, the radio of the controller 250 can be activated. Correspondingly, the controller 250 may receive an instruction input by the user through the user interface.

The controller 250 may also be in response to an instruction for playing a video initiated by the user through the remote control. For example, if the user wants to watch a video, he presses a corresponding button on the remote control. At this time, the remote control sends an instruction for playing the video to the controller 250.

The embodiments of the present application only exemplarily show two ways of sending instructions for playing videos. In actual applications, the ways of sending instructions for playing videos are not limited to the above two ways.

S102 reads the first display direction and the second display direction. The first display direction is the display direction supported by the currently playing video, and can also be understood as the target display direction. The second display direction is the current display direction of the display 275. Display direction

In this embodiment, in response to the playing of the video, the controller 250 may obtain whether the target display direction is the horizontal display direction or the vertical display direction, and whether the second display direction is the horizontal display direction or the vertical display direction by executing a related program. There are many ways to determine the first/second display direction.

For example, the controller 250 may determine the target display direction by reading the resolution of the video. The resolution of the video includes the width and height of the video. If the width is greater than the height, the display direction of the video is the horizontal display direction; if the width is less than the height, the display direction of the video is the vertical display direction.

Specifically, after the action of loading the video is completed, the attribute value of the video is also stored in the local memory of the controller 250. At this time, the controller 250 can determine the target display of the video by calling the resolution in the attribute value. direction. The resolution records the number of pixels included in the video in the two dimensions of "horizontal" and "vertical". 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). Based on the resolution, it can be known whether the video is a horizontal screen display video or a vertical screen display video.

In a feasible embodiment, if the resolution of the video loaded by the controller 250 is 320×240, the controller 250 determines that the video is a horizontal display video, and the corresponding first display direction is a horizontal display direction. In another feasible embodiment, the controller 250 retrieves the loaded video with a resolution of 768*1024, and the controller 250 determines that the video is a vertical screen display video, and accordingly, the first display direction is a horizontal display direction .

For another example, to add a direction indicator to the configuration information, the controller 250 may obtain the configuration information of the video being played through the application; then, based on the configuration information, determine whether the first display direction is the horizontal screen display direction or the vertical screen display direction.

Specifically, the controller 250 is further configured to: read a direction indicator; if the display direction indicator is a first direction indicator, the display direction supported by the video is a horizontal display direction; if the display direction indicator is If it is the second direction indicator, the display direction supported by the video is the vertical display direction. In the actual application process, the first identification value and the second identification value can be set according to requirements, and the applicant does not make too many restrictions here. The identification value can be added to the configuration information: com.android, H/V/HV, H indicates that the video only supports horizontal display orientation, V indicates that the video only supports vertical display, and HV indicates that the video supports both horizontal display and vertical display. direction.

In a feasible embodiment, the controller 250 retrieves the direction identifier of the video: com.android, H, and the controller 250 determines that the display direction supported by the video is the horizontal display direction. In another feasible embodiment, the controller 250 reads the direction identifier of the video: com.android, V, and the controller 250 determines that the first display direction is the vertical display direction.

The current display direction (second display direction) of the display 275 can be monitored by a sensor built into the display device 200. For example, the display 275 of the display device 200 is provided with a gyroscope, a gravity acceleration sensor, etc., and the posture data of the display 275 relative to the direction of gravity can be determined by measuring the angular acceleration or the direction of gravity. The monitored posture data is then compared with the posture data in the horizontal display direction and the vertical display direction, respectively, to determine the display direction where the display 275 is currently located.

For another example, a grating angle sensor, a magnetic field angle sensor, or a sliding resistance angle sensor, etc. can be arranged on the rotating component 276, and the angle rotated by the rotating component 276 can be measured and compared with the angle in the horizontal display direction and the vertical display direction. , To determine the current display direction of the display 275.

The embodiments of the present application are only illustrative of several ways of determining the first/second display direction. In the actual application process, the ways of determining the first/second display direction are not limited to the above-mentioned methods.

S103: If the first display direction is inconsistent with the second display direction, control the rotating assembly 276 to drive the display 275 to rotate, so that the display direction of the display 275 after the rotation is consistent with the first display direction.

In the actual display adaptation process, if the first display direction and the second display direction are inconsistent, the rotating assembly 276 is controlled to drive the display 275 to rotate, so that the display direction of the rotated display 275 is the same as the first display direction. Unanimous.

In this embodiment, the display direction of the display 275 may be a horizontal display direction or a vertical display direction. When the display 275 needs to be controlled to rotate, the controller 250 controls the rotating assembly to drive the display 275 to rotate.

In some implementations, the user can input an operation instruction to trigger the rotation to the display device 200, so that the display direction of the display 275 is changed from the horizontal display direction to the vertical display direction, that is, the display device is changed from the horizontal screen media viewing mode to the vertical display direction. The screen media viewing mode; or the display direction of the display 275 is converted from the vertical screen display direction to the horizontal screen display direction, that is, the display device is converted from the vertical screen media viewing mode to the horizontal screen media viewing mode.

For example, in the horizontal screen media viewing mode, the user watches cable TV, and after a period of time the user wants to watch vertical screen media resources, the controller 250 controls the rotating component 276 to drive the display 275 after receiving the application switching instruction sent by the user. Spin. The above control process can be understood as active input.

For example, the switching between the horizontal screen media viewing mode and the vertical screen media viewing mode may be a control command actively issued by the controller 250; for example, the controller 250 may monitor the display direction of the playing media and the display of the current display 275 in real time. Direction. When the display direction of the media asset is inconsistent with the display direction of the display 275, the active control rotating component 276 is controlled to drive the display 275 to rotate.

The media assets in this application can be, but are not limited to, videos, pictures, animations, and application interfaces. In this embodiment, a video is taken as an example to illustrate the processing flow of the display device.

For example, if the angle sensor detects that the current rotation angle of the display 275 is 90 degrees, it can be determined that the display direction of the display 275 is the vertical display direction, and when the first display direction is read as the horizontal display direction, the display 275 can be rotated , So that the display direction of the rotated display 275 is the vertical display direction.

For another example, if the angle sensor detects that the current rotation angle of the display 275 is 90 degrees, it can be determined that the display direction of the display 275 is the horizontal display direction, and when the first display direction is read as the vertical display direction, the display 275 can be performed Rotate so that the display direction of the rotated display 275 is the horizontal display direction.

S104, in response to the display 275 starting to rotate, record the rotation time, where the rotation time is used to record the time length of the rotation of the display 275.

In this embodiment, in response to the display 275 starting to rotate, the controller 250 records the rotation time. There are many ways to determine the starting direction of the display 275 to rotate.

For example: refer to FIG. 9, which is a flow chart showing the operation of the controller 250 according to a feasible embodiment, and the controller 250 is further configured to perform the following steps:

S1041 collects a first rotation speed, where the first rotation speed is used to record the rotation speed of the display 275;

In this application, a sensor may be provided on the controller 250 to monitor the first rotation speed of the display 275 in real time. Normally, the first rotation speed is 0, that is, the display 275 is in a static state.

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

In the actual application process, the preset rotation speed can be set according to requirements. In a feasible embodiment, the preset rotation speed can be 0.01 degrees/ms. The controller 250 collects a first rotation speed every 20 ms. When the collected first rotation speed is greater than 0.01 degree/ms, the controller 250 starts to record the rotation time. The corresponding actual recording method may be that when the collected first rotation speed is greater than 0.01 degree/ms, the corresponding time is the start 0 of the rotation time.

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

During the rotation of the display 275, the first rotation speed is continuously greater than the preset rotation speed, and when the display 275 stops rotating, the first rotation speed is less than the preset rotation speed.

In the actual application process, the display 275 may be rotated under the action of an external force. At this time, the first rotation speed recorded by the controller 250 may be greater than the preset rotation speed. In order to avoid the occurrence of the above-mentioned problem, in this embodiment, the controller 250 may start to record the rotation time when the first rotation speed collected for n consecutive times is greater than the preset rotation speed.

For another example, it can be approximated that when the controller 250 issues a rotation instruction, the display 275 starts to rotate. This embodiment is only illustrative of two implementations for determining the starting rotation direction of the display 275. In the actual application process, the implementation for determining the starting rotation direction of the display 275 may be, but not limited to, the above two implementations.

The drawing parameters in this application of the present application at least include the page refresh rate of the display device. In this application, drawing parameters include at least: the page refresh rate, target time, and target angle of the display device;

The page refresh rate, target time, and target angle may be stored in the memory of the controller 250 in advance.

In the actual application process, the target angle can be set according to requirements. Usually, the display 275 is switched between the horizontal display mode and the vertical display mode. Therefore, in some feasible embodiments, the target angle setting can be set, but not Limited to 90 degrees.

The page refresh rate is determined by the performance of the display device. In some feasible embodiments, the page refresh rate may be 60 times per second.

In some feasible embodiments, the controller 250 may count the time required for the display device to rotate to the target angle in advance, then generate the target time according to the statistical result, and then store the target time for subsequent applications. The process of generating the target time may be that the controller 250 is configured to perform steps 21 to 23 to generate the target time.

In the actual application process, the first preset angle can be set according to requirements. In a feasible embodiment, the first preset angle is set to 90 degrees.

...

Nth rotation: The controller 250 controls the rotation of the display, and at the same time records the time T _90,N required for the display 275 to rotate 90 degrees.

S1052 counts the probability of occurrence at each time;

The controller 250 counts the occurrence probability of _{T θ,1} , T _θ,2 ... T _θ,N.

FIG. 11 is a graph showing _{the relationship between T θ, N-} P according to a feasible embodiment, where the abscissa mark T _{θ, N} is the time required for the display 275 to rotate θ, and P is the probability _{of T θ, N appearing.}

S1053 screens out the time when the probability is greater than the preset probability as the target time;

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

Please continue to refer to Figure 11, any time between Ti and Tj can be used as the target time.

S1054 calculate the rotation speed according to the first preset angle and the target time;

The rotation speed can be calculated according to the following formula:

Among them, V is the rotation speed, θ is the first preset angle, and T _{θ, N} is the target time.

In a feasible embodiment, θ=30 degrees, calculated according to the above method:

In a feasible embodiment, θ=90 degrees, calculated according to the above method:

S1055 stores the rotation speed.

Specifically, the process of drawing a video picture may be: the control of the rotation component 276 drives the display 275 to rotate in a first direction; the controller 250 is further configured to: control the video picture to rotate in a second direction The angle is predicted so that the video picture remains relatively still, wherein the first direction and the second direction are correlated.

There are multiple implementation manners for drawing the video picture based on the predicted angle;

For example, in a feasible embodiment, the pre-stored rotation angle is 0.01 degree/ms. When the controller 250 controls the rotating component 276 to drive the display 275 to rotate clockwise, the controller 250 calculates a predicted angle of 0.2 degrees at 20ms, the controller 250 configures the video screen to initialize OpenGL, configures the OpenGL environment, loads video resources, and sets video parameters . At the beginning of the content of the video screen, the angle of each screen model is rotated by 0.2 degrees counterclockwise, and the angle will follow the change of the predicted angle in the subsequent configuration process. To ensure that the video page rotates, it always rotates around the center of the display 275. For example, the size of the display 275 is W*H, and the corresponding video image is rotated around the point (W/2, H/2).

For example, in a feasible embodiment, the pre-stored rotation angle is 0.01 degree/ms. When the controller 250 controls the rotating component 276 to drive the display 275 to rotate clockwise, the controller 250 calculates a predicted angle of 0.2 degrees at 20ms, the controller 250 configures the video screen to initialize OpenGL, configures the OpenGL environment, loads video resources, and sets video parameters . The content of the starting video screen, the angle of each screen model is clockwise rotated -0.2 degrees, in the subsequent configuration process, the angle will change with the change of the predicted angle. To ensure that the video page rotates, it always rotates around the center of the display 275. For example, the size of the display 275 is W*H, and the corresponding video image is rotated around the point (W/2, H/2).

The operation process of the display device shown in the embodiment of the present application will be described in detail below with reference to specific examples:

FIG. 12A is a diagram showing a change of the video image during the rotation of the display 275 according to a feasible embodiment. In the initial state, the current display direction of the display 275 is the horizontal display direction. The user triggers an instruction to play a vertical media asset (such as a video) to the controller 250, and the controller 250 controls the display device to display the video. At this time, the video screen can refer to the screen 31. The controller 250 determines that the display direction supported by the video is the vertical display direction by reading the resolution of the video. The current display direction of the display 275 is inconsistent with the display direction supported by the currently played video, and the controller 250 controls the rotation component 276 to drive the display 275 to rotate clockwise, so that the display 275 is rotated from the horizontal screen state to the vertical screen state; The display 275 starts to rotate, and the controller 250 records the rotation time. The controller 250 generates a predicted angle according to the rotation time and the pre-stored rotation speed (0.01 degree/ms); each time the video screen is drawn, the content of the video screen is controlled to rotate the predicted angle counterclockwise, and the video screen is rotated during the rotation process. See screen 32, screen 32, screen 33, screen 34, and screen 35. In this embodiment, the video picture rotates at a uniform speed at a rotation speed of 0.01 degree/ms, and the video picture changes smoothly during this process, and the user experience is better.

FIG. 12B is a diagram showing the change of the video image during the rotation of the display 275 according to another feasible embodiment. In the initial state, the current display direction of the display 275 is the vertical display direction. The user triggers an instruction to play horizontal media assets (such as a video) to the controller 250, and the controller 250 controls the display device to display the video. At this time, the video screen can refer to the interface 41. The controller 250 determines that the display direction supported by the video is the horizontal display direction by reading the direction indicator of the video. The current display direction of the display 275 is inconsistent with the display direction supported by the currently played video, and the controller 250 controls the rotation component 276 to drive the display 275 to rotate clockwise, so that the display 275 rotates from the vertical screen state to the horizontal screen state. In response to the display 275 starting to rotate, the controller 250 records the rotation time. The controller 250 generates a predicted angle according to the rotation time and the pre-stored rotation speed (0.01 degree/ms); each time the video screen is drawn, the content of the video screen is controlled to rotate the predicted angle counterclockwise, and the video screen is rotated during the rotation process. See screen 42, screen 43, screen 44, and screen 45. In this embodiment, the video picture rotates at a uniform speed at a rotation speed of 0.01 degree/ms, and the video picture changes smoothly during this process, and the user experience is better.

It can be seen that the embodiment of the present application shows a display device, and the display device includes a display 275, a rotating component 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 at the same time, the controller 250 reads the first display direction and the second display direction; if the first display direction and the second display direction If the display directions are inconsistent, the controller 250 controls the rotating assembly 276 to drive the display 275 to rotate. When the display 275 starts to rotate, the controller 250 records the rotation time. Each time a video screen is drawn, the controller 250 calculates a predicted angle according to the rotation time and a pre-stored rotation speed; the controller 250 draws the video screen based on the predicted angle. During the rotation of the display 275 of the display device 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, even if the display 275 is rotated during the rotation. In the case where a large jitter occurs when the limit switch is touched, the controller 250 can also obtain an appropriate predicted angle based on the current rotation time and rotation speed. In this application, the prediction angle increases uniformly with time, so that the video screen configured based on the prediction angle rotates at a uniform speed with the increase of time. In this process, the video screen changes smoothly, and the user experience is better.

In other embodiments, the operation flow of the display device can be referred to FIG. 7. The display device shown in the embodiment of the present application includes: a display 275, a rotating component 276, and a controller 250, wherein:

The display 275 is used to display the display page.

The rotating component 276 is connected to the display 275 and is configured to drive the display 275 to rotate;

The controller 250 is configured to perform the following steps:

S301 controls the rotating assembly 276 to drive the display 275 to rotate;

In S302, in response to the display 275 starting to rotate, call drawing parameters. The drawing parameters in this application include at least the page refresh rate of the display device;

S303 draws the display page of the display 275 according to the drawing parameters, so that the drawn display page matches the page refresh rate of the display device, the rotation angle of the display page is consistent with the rotation angle of the display 275, and the rotation direction of the display page is the same as the rotation direction of the display 275 on the contrary.

In order to prevent page jitter in this application, the drawing frequency of the display page is not less than the page refresh rate of the display device. Preferably, the drawing frequency of the display page is equal to the page refresh rate of the display device.

There are many ways to control the drawing frequency of the display page to be consistent with the page refresh rate of the display device.

For example, in some feasible embodiments, the page refresh rate of the display device is 60 times per second. Accordingly, the controller 250 can draw 60 display pages per minute, so that the rendered display page matches the page refresh rate of the display device. .

For another example, in some feasible embodiments, the page refresh rate is 60 times per second. The controller 250 can calculate that the display device refreshes the page every 1/60 second, and the controller 250 uses the time when the display 275 starts to rotate as the starting point for timing. , A display interface is drawn every 1/60 second, so that the drawn display page matches the page refresh rate of the display device.

This embodiment only exemplarily shows two implementations for controlling the drawing frequency of the display page to be consistent with the page refresh rate of the display device. In the actual application process, the drawing frequency of the display page and the page refresh rate of the display device are controlled. The consistent implementation can be, but is not limited to the above two implementations.

There are many ways to control the rotation direction of the display page to be opposite to the rotation direction of the display 275.

For example, the controller 250 can read the rotation direction of the display 275, and then control the display page to rotate in the opposite direction to the rotation direction selected by the rotator. In some feasible embodiments, the rotation direction of the display 275 is clockwise rotation, and the rotation direction of the corresponding display page is counterclockwise rotation.

For another example, the controller 250 may pre-store the rotation direction of the display 275, and when the display page needs to be drawn during the rotation process, the controller 250 controls the display page to rotate in the opposite direction to the rotation direction selected by the rotator.

The embodiments of the present application only exemplarily show two implementations for controlling the rotation direction of the display page to be opposite to the rotation direction of the display 275. In the actual application process, the control process can be configured according to the actual application environment. Here, the applicant Not limited.

There are many ways to control the rotation angle of the display page to be consistent with the rotation angle of the display 275.

For example, the controller 250 calculates the rotation step size DR (detRotation) of each drawn display page according to drawing parameters, and then draws the display page according to the page refresh rate, and each drawn display page is rotated by an angle of R2 (Rotation), R2=DR *a, where R2 is the rotation angle, the unit is degrees, and a is the page drawing times, the unit is times.

For another example, the controller 250 calculates the rotation step RT of each drawn display page according to the drawing parameters, and then draws a display page every interval D2, and each drawn display page is rotated by an angle of R2, where D2 (Duration) is the page Refresh time, the unit is second, D2=1/f.

Among them, the calculation process of the rotation step length is as follows:

Controller 250DR=R1/D1/f, where f is the page refresh rate, the unit is times/second; D1 is the target time, the unit is seconds; R1 is the target angle, the unit is degrees; DR is the rotation step length, the unit is Degree/time; Calculate the rotation angle according to the following formula; R2=DR*a, where R2 is the rotation angle and the unit is degrees, and a is the number of times the page is drawn, and the unit is times.

In some feasible embodiments, R=90°, D=6S, f=60 times/second; DR=90/6/60 degrees/time=0.25 degrees/time.

The embodiment of the present application only exemplarily shows two implementations of controlling the rotation angle of the display page to be consistent with the rotation angle of the display 275. In the actual application process, the control process can be configured according to the actual application environment. The applicant does not Be limited.

The drawing process of the display page will be described in detail below in conjunction with specific examples.

In some feasible embodiments, R=90°, D=6S, f=60 times/second (or Hz); DR=90/6/60 degrees/time=0.25 degrees/time.

In some embodiments, when the controller 250 controls the rotating component 276 to drive the display 275 to rotate clockwise, the controller 250 draws the first frame of the display page at 1/60s, where the rotation angle of the first frame of the display page is 0.25 The drawing process is roughly as follows: the controller 250 configures the display page to initialize OpenGL, configures the OpenGL environment, loads resources, sets resource parameters, and renders the content of the display page. The angle of the page model is rotated counterclockwise by 0.25 degrees. Draw the first frame of the display page at 2/60s, where the rotation angle of the first frame of the display page is 0.25*2 degrees, the content of the display page, the angle of each page model is 0.50 degrees counterclockwise...until the controller 250 stops rotating.

In other embodiments, when the controller 250 controls the rotating component 276 to drive the display 275 to rotate clockwise, the controller 250 draws the display page at a drawing frequency of 60 Hz, and the rotation angle of the display page drawn each time is: 0.25 degrees, 0.25*2 degrees, 0.25*3 degrees...90 degrees. The drawing process is roughly as follows: the controller 250 configures the display page to initialize OpenGL, configures the OpenGL environment, loads resources, sets resource parameters, and renders the content of the display page. The angle of the page model is rotated 0.25 degrees counterclockwise.

It is worth noting that the controller 250 needs to calculate the rotation angle in real time only when the display 275 is rotating. When the display 275 stops rotating, the controller 250 terminates the drawing of the rotation angle.

There are many ways to determine that the display 275 stops rotating.

For another example: the controller 250 is further configured to record the rotation angle, and if the rotation angle is equal to 90 degrees, the display 275 stops rotating.

For another example: the controller 250 is further configured to record the rotation time, and if the rotation angle is equal to the target rotation time, the display 275 stops rotating.

For example, the target rotation time is 6 seconds. When the controller 250 detects that the rotation speed of the display 275 is greater than the preset rotation speed, the controller 250 starts timing. When the time recorded by the display 275 is equal to 6 seconds, the display 275 stops rotating.

S404 controls the display 275 to display the display page.

In the implementation shown in the embodiments of the present application, the video includes wired video and network video, where the network video includes: a video picture and a graphics layer picture covering an upper layer of the video picture. The graphics layer screen is also referred to as OSD (Object Sequence Diagram, on-screen menu adjustment mode) in the embodiments of the present application, and the graphics layer screen is displayed in a fixed or non-fixed manner. For example: the graphics layer screen can be used to superimpose various notifications and other information with characters while playing a video program. When the user needs to know a certain information, the corresponding graphics layer screen is called, and the graphics layer screen is cancelled after a period of time. For example, if the user wants to know the volume of the currently playing video, the user can use voice or remote control to call up the graphic layer picture corresponding to the volume. The display 275 displays the graphic layer picture corresponding to the volume, and the graphic layer picture corresponding to the volume is cancelled after 20 seconds. The graphics layer picture is displayed on the display 275 when the user calls it through voice or remote control. Generally, during the rotation of the display 275, the display 275 does not display the graphics layer picture associated with the control menu.

In other embodiments, the video is generally displayed on the video layer to achieve high-quality image quality processing, and the OSD layer cannot achieve image quality processing. The Video layer cannot rotate the image in real time based on the rotation of the display device, while the OSD layer can rotate the image in real time based on the rotation of the display device. Therefore, when the video is rotating, the image in the video is generally transmitted to the OSD layer for image rotation. After the display stops rotating, the OSD layer transmits the video layer data to the video layer.
