The rotary television is a novel intelligent television and mainly comprises a display and a rotary component. Wherein, the display passes through rotatory subassembly to be connected on support or wall, and the angle is placed to the adjustable display of accessible rotatory subassembly, reaches rotatory purpose. Different display placement angles can accommodate animated pages of different aspect ratios, for example, in most cases the display is placed sideways to display video pages of movies, television shows, etc. with an aspect ratio of 16. When the aspect ratio of a video page is a page of a short video, caricature, etc. of 9. Thus, the display can be vertically positioned by the swivel assembly to accommodate a 9.

The applications supported by the rotary television are numerous, and a starting signal source of the television can be appointed by setting a starting mode so as to be convenient for a user to watch. 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 display postures 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 page corresponding to the application of the starting-up signal source can be normally displayed.

However, when watching the television, the user can adjust the posture of the display of the rotating television according to the requirement and still keep the adjusted posture when turning off the television. 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. If the power-on signal source is set to be an application only supporting the horizontal placement state, the screen posture is not matched with the power-on signal source application, and the screen cannot be displayed correctly. Therefore, the application provides a display device and a display method of an application interface.

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 input by a user, such as a power switch signal, a channel selection signal, a volume adjustment signal, etc., to the user interface 265, and then the input signal is forwarded 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, the user may enter user commands in 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 common 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 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.

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

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 and also displays 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 component for rendering pages and a driving component that drives the display of images. Alternatively, a projection device and projection screen may be included, provided that display 275 is a projection display.

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 noise reduction, digital-to-analog conversion, and amplification processing on the received audio signal to obtain an audio signal that can be played in the microphone 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 microphone 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.

Since the display device 200 provided by the present application includes the display 275 and the rotating assembly 276, the rotating assembly 276 can rotate the display 275 to make the display 275 have 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 orientation is a display orientation 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 when the display 275 is in the landscape orientation may be referred to as the landscape viewing mode, and the mode of operation when the display 275 is 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 and obtaining corresponding data. The display 275 in the display device 200 can be rotated 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-screen asset viewing mode and a portrait-screen asset 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 page with the ratio of 9:16, etc., such as short videos shot through a terminal like a mobile phone, etc. Because terminal equipment such as cell-phone adopts 9 more: 16,9:18, and the like, when the terminal accesses the display device 200 and displays a terminal page through the display device 200, the vertical screen display direction can avoid excessive zooming of the page, the application interface 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; the transverse media assets such as TV dramas and movies can still be displayed in the vertical screen display direction, and only the incompatible 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 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 a 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.

The display device may start a plurality of applications in a working process, and the applications related in the embodiment of the present application include a horizontal screen application and a vertical screen application, where a display direction of the horizontal screen application is a horizontal screen display direction, and a display direction of the vertical screen application is a vertical screen direction. Generally, when a display device starts a plurality of applications, the display device needs to adjust a display direction according to a currently displayed application interface, which requires the display device to frequently adjust the display direction of the display. For example, the first application started by the display device is a landscape screen application, the display direction of the corresponding display is a landscape screen display direction, when the display starts the second application (the second application is a portrait screen application), the display device adjusts the display direction of the display to be a portrait screen display direction, and when the display starts the third application (the third application is a landscape screen application), the display device adjusts the display direction of the display to be a landscape screen display direction.

In order to solve the foregoing technical problem, an embodiment of the present application provides a display device, where the display device at least includes: a display, a rotating assembly and a controller; the functions and connection modes of the display, the rotating assembly and the controller can refer to the above embodiments, and are not described herein.

Operation flow diagram of a display device referring to fig. 6, fig. 6 is a flowchart of operation of a display device according to a possible embodiment, wherein:

the controller is configured to execute step S101, when the display is in the landscape display direction, each time the application is started, read the display direction of the current application interface, where the current application interface is an application interface of the started application;

when the user wants to start the application, the user can start the application by sending an application start instruction to the display device. In some feasible embodiments, the application start instruction may be an instruction sent by the user in the form of voice; the sending process of the application start instruction may be: the user outputs a wakeup word in advance and then outputs an application start instruction, and the user establishes a connector connection with the controller 250 based on the wakeup word so that the controller 250 can respond to the application start instruction output by the user accordingly. For example, the user inputs a wake word "little congruence" and an application start instruction "start karaoke application". In some feasible embodiments, the application start instruction may be an application start instruction sent by a user through a remote controller; the sending process of the application start instruction may be: the user touches the relevant control of the remote controller, so that the controller 250 can send a corresponding application start instruction, and the controller 250 can respond to the application start instruction accordingly. For example, the user may trigger the remote controller to send an application start command to the controller 250 by clicking a confirmation key of the remote controller. In the present embodiment, only two display device starting modes are provided by way of example, and in the process of actual application, the sending process of the application starting instruction may be, but is not limited to, the two modes.

The implementation manner of reading the display direction of the current application may be:

the application interfaces are divided into a floating layer interface and a non-floating layer interface in the present application. The floating layer interface refers to a temporary application interface for opening an application on the current page. These temporary application interfaces can accomplish suggestive or context-dependent tasks that are less disruptive and maintain a more consistent use experience for the user. The float interface may also be referred to as "float", "bullet box", etc. The non-floating layer interface is an application interface which is used for displaying components of the characteristics and functions of the application interface facing the outside, and usually occupies the whole application interface in the displaying process. Therefore, the experience of the user is directly influenced by the display effect of the non-floating layer interface. The scheme shown in the embodiment of the application firstly determines the currently applied non-floating layer interface before controlling the display to rotate.

The non-float interface can be found by the following method; a controller 250 further configured to perform the following steps (11) - (13);

step (11) acquiring a Task list running in the foreground, acquiring first Activity information from the first Task list, and judging whether an application interface corresponding to the first Activity information is a floating layer interface or not;

the way of obtaining the Task list running in the foreground can be to input a Task command into a port of the system, and all processes of the machine can be displayed in the Task list. The Tasklist command may view not only the system processes, but also each incoming Activity information. Whether the process application interface is a non-floating interface can be determined by identifying the Activity information of the process application interface.

The implementation manner of determining whether the process application interface is a non-floating layer interface through the Activity information is various:

for example, whether the application interface corresponding to the Activity information is a non-floating interface can be determined by whether the Activity information is stored in the floating interface list.

For example, it may be determined whether a first Activity information is stored in a floating layer interface list, where the floating layer interface list is used to record Activity information of a floating layer interface in the display device; if the first Activity information is stored in the floating layer interface list, determining that the application interface corresponding to the first Activity information is a floating layer interface; otherwise, determining that the application interface corresponding to the first Activity information is a non-floating layer interface. In the embodiment of the application, activity information of the floating layer interface is stored in a floating layer interface list in advance, and the floating layer interface list is stored in a memory. Controller 250 may retrieve the list of float interfaces as needed during operation.

It is worth noting that each application corresponds to a plurality of process application interfaces, and for any application, the number of non-floating layer interfaces is much larger than that of floating layer interfaces, and based on this, the scheme shown in the embodiment of the present application generates a floating layer interface list according to Activity information of a floating layer interface of the application for any application. The data recorded in the floating layer interface list is less, so that on one hand, the available capacity of the memory of the display equipment can be improved, and further, the data processing efficiency of the display equipment is improved; on the other hand, in the process of determining whether the first Activity information is stored in the floating layer interface list, the controller 250 needs to traverse the floating layer interface list, and the data recorded in the floating layer interface list is less, so that the corresponding traversal efficiency is improved.

And for example, whether the application interface corresponding to the Activity information is a non-floating layer interface can be determined through the application interface theme of the Activity information. Specifically, reading an application interface theme of the first Activity information; if the theme of the application interface is a transparent theme, determining that the application interface corresponding to the first Activity information is a floating layer interface; otherwise, determining that the application interface corresponding to the first Activity information is a non-floating layer interface.

Each Activity information is recorded with an application interface theme, the application interface theme is recorded with a setting value corresponding to the application interface, and the setting value may include setting values such as an application interface style, an application interface title, and an application interface transparency. Wherein the transparency may include: layout transparency, activity transparency, color transparency, background transparency, etc. The controller 250 may determine whether the application interface corresponding to the Activity information is a non-floating interface according to the setting value of the transparency.

Step (12) in response to that the application interface corresponding to the first Activity information is not a floating interface, determining that the application interface corresponding to the first Activity information is a non-floating interface;

and (13) in response to that the first Activity information is a floating layer interface, searching for second Activity information in the first Task list, and searching for a second Task list when the first Task list is searched and a non-floating layer interface is not found, and sequentially performing until the non-floating layer interface is found.

It should be noted that an application interface corresponding to an application may include a floating layer interface and a non-floating layer interface, or may include only a non-floating layer interface. The implementation manner for determining the non-suspension layer interface shown in the above embodiment is adopted.

The non-floating layer interface determined by the controller 250 for the first time is the application interface of the current application.

And determining the display direction of the application according to the configuration information of the non-floating layer interface. Generally, the screen orientation in the configuration information represents the display direction of the application. In one possible implementation, the screen orientation is landscreen, which indicates that the display direction of the application is the Landscape display direction, and in one possible implementation, the screen orientation is portait, which indicates that the display direction of the application is the Portrait display direction.

The controller is configured to execute step S102, if the display direction of the current application interface is the vertical-screen display direction, control the rotating assembly to drive the display to rotate from the horizontal-screen display direction to the vertical-screen display direction, and delete the started horizontal-screen application.

And in the initial state, the display direction of the display is the horizontal screen display direction, and when the display direction of the current application interface read by the controller is the vertical screen display direction. The controller may control the rotation component to rotate the display 275, so that the display direction of the rotated display 275 is the vertical display direction. In this embodiment, when the display is rotated from the landscape screen state (corresponding to the display direction being the landscape screen display direction) to the portrait screen state (corresponding to the display direction being the landscape screen display direction). The controller deletes all horizontal screen applications started before, so that when the display is in a vertical screen state, only the vertical screen applications are started, further the display is prevented from being switched between the horizontal screen state and the vertical screen state, and further the display is prevented from being damaged due to frequent switching between the horizontal screen state and the vertical screen state.

In the technical scheme shown in the embodiment of the application, the display identification position is adopted to record the display direction of the display, for example, when the display is in the horizontal screen display direction, the display identification position is the horizontal screen display identification position, and when the display is in the vertical screen display direction, the display identification position is adjusted to the vertical display position by the horizontal display position.

Based on the display identification bit, the controller can determine whether to display the horizontal screen homepage or the vertical screen homepage by reading the identification bit each time the homepage is returned. For example, when the display is in the landscape display orientation, and the user controls the display device to return to the home page, the controller controls the display to display the landscape home page, which is used to display icons corresponding to all applications in the present application, because the display identification bit is the landscape display identification bit. For another example, when the display is in the vertical screen display direction, and the user controls the display device to return to the home page, because the display identification bit is the vertical screen indication bit, the controller controls the display to display a vertical screen home page, and the vertical home page is used for displaying an icon corresponding to the vertical screen application.

The controller is configured to execute step S103 to control the display to show the application interface.

The following describes the operation flow of the display device provided in the present application in detail with reference to specific examples:

in a possible embodiment, when the display device is powered on, the display is in a landscape state, in which the display is used to display a landscape home page, and fig. 7 is a schematic diagram of a landscape home page provided according to a possible embodiment, and it can be seen from the diagram that the landscape home page is used to display all applications installed on the display device, including a landscape application and a portrait application. Each time the controller is used for clicking the corresponding icon, the controller starts an application interface corresponding to the application. For example, the controller starts the application 1, the application 2, and the application 3 in sequence, where the application 1 is a horizontal screen application, the application 2 is a horizontal screen application, and the application 9 is a vertical screen application, an application stack constructed by the display device in this embodiment may refer to fig. 8, and corresponding interface changes may refer to fig. 9 in a process of starting multiple applications by the display device. When the display device starts the application 9, the controller reads the display direction of the application 9 as the vertical screen display direction, and the controller controls the rotating assembly to drive the display to rotate from the horizontal screen mode to the vertical screen mode. When the display is rotated to the vertical screen mode, the launched horizontal screen applications (application 1 and application 2) are deleted, and at this time, the application stack constructed by the display device can refer to fig. 10. When the user touches the return control, the display direction of the current display is the vertical screen display direction, and correspondingly, the display device displays a vertical screen homepage, and in the process of returning to the homepage, the interface change diagram of the display device can refer to fig. 11. When the user clicks the return home control, the controller controls the display to show the vertical screen home page, and fig. 12 is a schematic diagram of a vertical screen interface provided according to one possible embodiment.

In a possible embodiment, the controller is further configured to perform the steps of: responding to the modification of the display identification bit, and recording the rotation angle of the display; deleting the launched landscape application in response to the rotation angle being equal to the preset angle.

In a possible embodiment, the initial state display is in landscape mode, and the preset angle may be, but is not limited to, 90 degrees. In response to the modification of the display identification bit, the controller starts recording the rotation angle of the display, and when the rotation angle is equal to 90 degrees, the controller deletes the started landscape application. By adopting the scheme shown in the application, the situation that the display cannot rotate to the vertical screen display direction due to faults can be guaranteed, the horizontal screen application started before the display can still be stored in the controller, and after subsequent problems are solved, the horizontal screen application started before can be directly called by control.

In a possible embodiment, the controller is further configured to: and when the display is in the vertical screen display direction, responding to the starting of the current application interface, and controlling the display to display the current application interface.

In this embodiment, since the vertical screen home page is used to display the vertical screen application icon, when the display device is in the vertical screen display direction, all the applications started by the display are vertical screen applications. Therefore, when the display is in the vertical screen display direction, the display direction of the application does not need to be read by the controller when the application is started every time, and the display is directly controlled to display the application interface of the application.

Due to the fact that the size of the display device is large, the rotating speed is slow, 8-10 seconds are usually needed, and an application interface displayed by the display device can incline in the rotating process, so that the experience of a user is influenced.

Based on the above problems, according to the technical scheme shown in the embodiment of the application, the rotating animation can be configured in the rotating process of the display, the rotating animation is arranged on the upper layer of the application interface, and the rotating animation is always matched with the display direction of the display in the rotating process of the display, so that the user experience is better.

A specific implementation can be seen in fig. 13. FIG. 13 is a flowchart of the operation of a display device provided in accordance with a possible embodiment;

the controller is configured to execute step S201, when the display is in the landscape display direction, each time the application is started, read the display direction of the current application interface, where the current application interface is an application interface of the started application;

the display direction of the application interface may refer to the above embodiments, which are not described herein.

S202, if the display direction of the current application interface is the vertical screen display direction, controlling the rotating assembly to drive the display to rotate from the horizontal screen display direction to the vertical screen display direction;

the implementation manner of controlling the rotating assembly to drive the display to rotate from the horizontal screen display direction to the vertical screen display direction may refer to the above embodiments, and is not described herein again.

S203, if the display direction of the current application interface is the vertical screen display direction, adjusting the display identification position from a horizontal identification position to a vertical identification position;

s204, responding to the modification of the display identification position, displaying the rotating animation by the display of the controller, recording the rotating angle of the display, and positioning the rotating animation on the upper layer of the current application interface;

the rotation angle can be directly read by the controller, or the angle increment value of the display is read by the controller, and then the rotation angle is calculated by the angle increment value of the controller. For example: the controller receives the angle increment value of 0.1 degree every 10ms, and the corresponding rotation angles calculated every 10ms are respectively as follows: 0.1 degree, 0.2 degree, 0.3 degree, 823060, and 90 degrees.

In the present application, the rotation direction of the animation is opposite to the switching direction of the display at any time, and the rotation angle of the animation is the same as the rotation angle of the display. For example, in some feasible embodiments, the display is in the landscape display orientation in the initial state, and in response to the modification of the display identification bits, the controller 250 controls the rotating component 276 to rotate the display 275, so that the display orientation of the display 275 after rotation is the portrait display orientation; in this process, the controller reads the rotation angle of the display at a preset. At 10ms, the rotation angle read by the controller is 0.25 degrees in anticlockwise rotation, and the controller controls the rotation animation to rotate 0.25 degrees in clockwise rotation. According to the above process, a rotation animation is drawn based on the collected rotation angle until the display stops rotating.

S205 deletes the rotation animation in response to the rotation angle being equal to the preset angle.

Referring to fig. 14, an interface change diagram of a display during rotation of the display, fig. 14 is a diagram of an interface change displayed by the display during rotation of the display according to a possible embodiment.

The above embodiments illustrate solutions in which a chain motor (also referred to as a rotation assembly in this application) 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 can collide with the limit switch, so that the rotating angle of the display 275 is greatly changed, and correspondingly, when the display rotates to be close to 9 degrees, the rotating animation drawn based on the rotating angle can be greatly inclined.

In view of the above problems, the application itself provides a further improvement to the display device provided in the above embodiment, and fig. 15 is a flowchart of the operation of the improved display device, where fig. 15 is a flowchart of the operation of the display device provided in accordance with a possible embodiment;

the controller is configured to execute step S301, when the display is in the landscape display direction, each time the application is started, reading the display direction of the current application interface, where the current application interface is an application interface of the started application;

S302, if the display direction of the current application interface is the vertical screen display direction, controlling the rotating assembly to drive the display to rotate from the horizontal screen display direction to the vertical screen display direction;

S303, if the display direction of the current application interface is the vertical screen display direction, adjusting the display identification position from a horizontal identification position to a vertical identification position;

s304, responding to the modification of the display identification position, recording rotation time, wherein the rotation time is used for recording the rotation duration of the display;

the manner of determining the rotation of the display can be implemented in a manner conventional in the art, and will not be described herein.

S305, generating a predicted angle according to the rotation time and the rotation speed stored in advance;

the rotation speed is generated in advance in the application, and the rotation speed can be directly called when a prediction angle needs to be generated. Wherein the generation process of the rotation speed can be: the controller is configured to perform steps (21) - (24);

step (21) the controller records the time T required for the display 275 to rotate the first preset angle N times respectively _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: controller 250 controls display rotation while recording display 275 rotates 90 degreesRequired time T _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 。

Step (22) the controller counts the probability of occurrence at each time;

controller 250 tallies T _θ,1 ，T _θ,2 ……T _θ,N The probability of occurrence.

Step (23) the controller screens 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.

Step (24) calculating the rotation 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,N Is the target time.

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

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

in the present application, angle = rotation time rotation speed is predicted.

S306 draws a rotation animation based on the predicted angle.

S307 deletes the rotation animation in response to the rotation time being equal to the preset time.

The implementation direction of drawing the rotation animation based on the prediction angle is similar to the implementation manner of drawing the rotation animation based on the rotation angle, and is not described herein again.

In the process of rotating the display of the display device, the predicted rotation angle is calculated based on the rotation time and the rotation speed, the predicted angle is not influenced by the actual rotation angle of the display, and even if the display is greatly shaken due to the fact that the display touches the limit switch in the rotating process, the controller 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 rotary animation configured based on the prediction angle is rotated at a uniform speed along with the increase of time, the picture of the rotary animation is changed smoothly in the process, and the user experience is good.

The embodiment of the present application further illustrates a display device, and the operation flow of the display device can refer to fig. 16, where fig. 16 is an operation flow diagram of a display device provided according to a feasible embodiment;
