Description

Display device

Technical Field

The application relates to the technical field of rotating 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 pages by utilizing a screen of the smart television, and rich media resources are provided for the smart 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 page on the mobile phone.

However, since the page ratios corresponding to different applications or media assets from different sources are different, the smart tv is often used to display pages with different ratios from the traditional video ratio. 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 pages 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 smart television is generally in a horizontal 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 smart television, a vertical display page cannot be normally displayed due to the fact that the page proportion is not matched with the display screen proportion. Generally, the vertical display page needs to be zoomed to display completely, which not only wastes the display space on the screen, but also brings bad user experience.

Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the 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 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 may 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. having an aspect ratio of 16: 9. When a video page is a 9:16 aspect ratio page of short video, caricature, etc., the horizontally positioned display needs to zoom the page and display black areas on both sides of the display. Thus, the display can be positioned vertically by rotating the assembly to accommodate a 9:16 ratio video page.

The applications supported by the rotary 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 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 tv, the user can adjust the display posture of the rotating tv as required, and still keep the adjusted posture when turning 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. Therefore, the application provides a display device and a display method of an application interface.

In order to facilitate a user to display a target media asset detail page in different horizontal and vertical screen display directions 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.

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.

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 an RGB data signal.

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 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 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.

Because the display device 200 provided by the present application includes the display 275 and the rotating component 276, the rotating component 276 can rotate the display 275, so that the display 275 can 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 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 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 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 page 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 page through the display device 200, the vertical screen display direction can avoid excessive zooming of the page, 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 may 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 page scale of a vertical application such as a short video.

There is an application scenario where the rotating television rotating assembly does not have the condition of driving the display to rotate; however, the display device does not provide any prompt for the user, and the user knows that the rotating component of the display device does not have the condition of driving the display to rotate after sending the rotating command to the display device for multiple times, so that the user experience is poor.

In order to improve the experience of the user, the embodiment of the application shows a display device, and the work flow of the display device can refer to fig. 6. 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 displaying the presentation page.

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 steps S101-S104;

s101, receiving a rotation instruction;

in some implementations, the user may input an operation instruction (also referred to as a rotation instruction in this embodiment) for triggering rotation to the display device 200, so that the display direction of the display 275 is converted from the landscape display direction to the portrait display direction, that is, the display device is converted from the landscape viewing mode to the portrait viewing mode; or the display direction of the display 275 is changed from the vertical screen display direction to the horizontal screen display direction, that is, the display device is changed from the vertical screen asset viewing mode to the horizontal screen asset viewing mode.

For example, in the landscape mode, when the user watches cable tv and wants to watch tremble audio after a certain period of time, the user may send a rotation command to the controller 250, and the controller 250 controls the rotating component 276 to rotate the display 275 after receiving the rotation command sent by the user. The control process described above can be understood as an active input.

For example, the switching between the landscape screen viewing mode and the portrait screen viewing mode may be a control instruction actively issued by the controller 250; for example, the controller 250 may monitor the display direction of the playing media asset and the current display direction of the display 275 in real time, and control the active control rotating assembly 276 to rotate the display 275 when the display direction of the media asset is not consistent with the display direction of the display 275.

S102, if the rotating assembly does not have the condition of driving the display to rotate, the display is controlled to display prompt information.

S103, the rotating assembly has the condition of driving the display to rotate, and the rotating assembly is controlled to drive the display to rotate;

there are various ways to determine whether the rotating component 276 has the condition for rotating the display.

For example, in a feasible embodiment, referring to fig. 7, the operation flow of the display device is shown in fig. 7, which is a flowchart of the operation flow of the display device according to a feasible embodiment. In response to the rotation instruction, the controller executes step S10211 to read an identification of a rotation port for connecting the rotating component 276, the identification being a first identification when the rotating component 276 is inserted into the rotation port; when the rotating component 276 is detached from the rotating port, the identification switches to a second identification; if the identifier is the first identifier, it is verified that the rotating component 276 has established a connection with the controller, and the controller executes step S103 to control the rotating component 276 to rotate the display by a preset angle. In this embodiment, the preset angle is not limited. If the identifier is the second identifier, the controller executes step S104 to control the display to display a prompt message, where the prompt message is used to prompt the user that the rotating component 276 is not inserted into the rotating port in this embodiment, at this time, the display interface of the display may refer to fig. 8, and fig. 8 is an exemplary schematic diagram illustrating a display interface, and it can be seen that when the controller reads that the identifier of the rotating port is the second identifier, the display displays a prompt message used to prompt the user that the rotating component 276 is not inserted into the rotating port.

For example, in practical applications, in order to prevent the rotation of the display device caused by the misoperation of the user, a rotation switch may be disposed in the display device, and the controller may control the rotation component 276 to rotate the display device when the rotation switch is in the on state, and the controller may not control the rotation component 276 to rotate when the rotation switch is in the off state. Specifically, referring to fig. 9, an implementation manner of determining whether the rotating element 276 has a condition for driving the display to rotate may be shown, and fig. 9 is a flowchart illustrating an operation of the display device according to a feasible embodiment. In response to the rotation instruction, the controller is configured to execute step S10221 to read the state of the rotary switch, and control the rotating assembly 276 to rotate the display to a preset angle if the rotary switch is in the on state. If the rotary switch is in the chopping state, controlling the display to display prompt information, wherein the prompt information is used for prompting a user that the rotary switch is in the chopping state; referring to fig. 10, a display interface of the display at this time, fig. 10 is a schematic diagram illustrating an exemplary display interface, and it can be seen that when the controller reads that the rotary switch is in the chopping state, the display displays a prompt message for prompting a user that the rotary switch is in the chopping state. The user can activate the rotary switch according to the prompt.

For example, in a possible embodiment, the operation flow of the display device can refer to fig. 11, and fig. 11 is a flowchart illustrating the operation flow of the display device according to a possible embodiment. In response to the rotation instruction, the controller is configured to perform step S10231 to read the identification of the rotation port. If the identification is a second identification, the control display presents a prompt for the user that the rotating assembly 276 is not inserted into the rotating port. If the identifier is the first identifier, the controller executes step S10232 to read the state of the rotary switch, and if the rotary switch is in the connected state, the controller controls the rotating assembly 276 to rotate the display to the preset angle. And if the rotary switch is in the chopping state, controlling the display to display prompt information, wherein the prompt information is used for prompting a user that the rotary switch is in the chopping state in the embodiment.

For example, in a possible embodiment, the operation flow of the display device can refer to fig. 12, and fig. 12 is a flowchart illustrating the operation flow of the display device according to a possible embodiment. In response to the rotation instruction, the controller executes step S10241 to read the state of the rotary switch, and if the rotary switch is in the chopping state, controls the display to display a prompt message for prompting a user that the rotary switch is in the chopping state; if the rotary switch is in the on state, the controller performs step S10242 to read the identification of the rotary port. If the identification is a second identification, the controller controls the display to present a notification message to the user that the rotating assembly 276 is not inserted into the rotating port. If the mark is the first mark, the controller controls the rotating component 276 to rotate the display to a preset angle.

Further, each rotating assembly 276 is limited by its structure, and may rotate a total angle in the clockwise direction, and the rotating assembly 276 may be damaged if the rotating assembly rotates in the clockwise direction by an angle greater than or equal to the total angle in the clockwise direction. Accordingly, there is a total angle of rotation in the counterclockwise direction, and typically the total angle of rotation in the counterclockwise direction is greater than or equal to the total angle of rotation in that direction, the rotating assembly 276 may be damaged.

In practice, when the display device may receive a positional restriction that results in a total angle of rotation in a clockwise direction, typically greater than or equal to the total angle of rotation in the clockwise direction, the rotating assembly 276 may encounter an obstacle during rotation of the dynamic display 275. Accordingly, there is also a total angle of rotation in the counter-clockwise direction, typically greater than or equal to the total angle of rotation in the counter-clockwise direction, and rotating assembly 276 may encounter an obstacle during rotation of movable display 275.

Based on the above scenario, the controller needs to determine a rotatable direction after receiving the rotation command, and the rotating component 276 only has a rotation condition when the rotatable angle in the rotatable direction is greater than the preset angle.

Specifically, the implementation manner of determining whether the rotating component 276 has the condition of driving the display to rotate may be:

in practical applications, the rotation command may include a control direction, such as "rotate left to vertical screen mode", and the rotation command may not include a control direction, such as "rotate to vertical screen mode". The technical scheme shown in the embodiment of the application adopts different processing modes according to whether the rotation instruction contains the control direction;

(1) in the case where the rotation command includes a control direction:

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

specifically, after receiving the rotation command, the controller 250 first identifies whether the rotation command includes the control direction, and if the rotation command includes the control direction, the processing flow of the display device may refer to fig. 13A, where the controller 250 is further configured to: step S10251 is performed to read the first rotation margin.

The first rotation allowance is a rotatable angle of the rotating assembly 276 in the control direction; (wherein, the pair of angles of rotation of the rotating assembly 276 in the control direction may also be referred to as the angle of rotation of the display in the control direction).

In this embodiment, the first rotation margin is a rotatable angle of the rotating component 276 in the control direction, which is a total angle that the control direction can rotate — an angle that the control direction has rotated;

wherein the control direction has rotated through an angle (also referred to as a real-time rotation angle) as a result of being monitored by the monitoring component 277.

The process of generating the first rotation margin is described in detail below with reference to specific examples.

In a possible embodiment the rotation command is "90 degrees clockwise" and the corresponding "clockwise" is the control direction. When receiving the rotation instruction, the controller 250 calls "360 degrees" as a total angle that can be rotated in the "clockwise" direction; controller 250 recalls the angle "0" degrees "that has been turned in the" clockwise "direction; the controller 250 calculates the first rotation margin as "360 degrees".

S103, in response to the fact that the first rotation allowance is larger than or equal to the preset angle, the control direction is determined to be the rotatable direction, and the rotating assembly is controlled to drive the display to rotate in the rotatable direction for the preset angle.

The following describes the determination process of the target direction in detail with reference to specific examples.

The rotation command may include a control angle, where the control angle is a preset angle, such as "90 degrees clockwise rotation" or "180 degrees clockwise rotation"; the rotation command may not include a control angle, such as "clockwise rotation to vertical screen mode" or "clockwise rotation to vertical screen mode". The embodiment of the present application shows that the technical solution is suitable for the rotation of the display 275, and usually the display 275 is switched between the "vertical screen mode" and the "horizontal screen mode", so that the rotation command may not include a control angle, and the preset angle is 90 degrees.

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

And S104, in response to the first rotation allowance being smaller than the preset angle, controlling the display to display prompt information for prompting a user that the display does not support rotation in the control direction, or, in response to the first rotation allowance being smaller than the preset angle, determining that the reverse direction of the control direction is the rotatable direction.

For the determination of the rotatable direction, reference may be made to the above embodiments, which are not described herein again.

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

(2) In the case where the rotation command does not include a control direction:

the controller 250 first identifies whether the user information includes the control direction after receiving the rotation instruction, and in response to the rotation instruction not including the control direction, the processing flow of the display apparatus may refer to fig. 13B, and the controller 250 is further configured to execute step S10261 to read a second rotation margin, which is a rotatable angle of the rotating element 276 in the preset direction.

In this embodiment, the second rotation allowance is a rotatable angle of the rotating component 276 in the preset direction, where the rotatable angle is a total angle that the preset direction can rotate — an angle that the preset direction has rotated;

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

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

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

S103, in response to the fact that the second rotation allowance is larger than or equal to the preset angle, the preset direction is determined to be the rotatable direction, and the rotating assembly is controlled to drive the display to rotate upwards for the preset angle;

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

In a possible embodiment the rotation command is "rotate 90 degrees" and in this embodiment "clockwise" is the preset direction. When receiving the rotation instruction, the controller 250 calls "360 degrees" as a total angle that can be rotated in the "clockwise" direction; controller 250 recalls the "360 degrees" angle that has been turned in the "clockwise" direction; the controller 250 calculates the second rotation margin as "0 degree".

S104 determines that the reverse of the preset direction is the rotatable direction in response to the second rotation margin being less than the preset angle.

In a possible embodiment, after determining the rotatable direction, the controller may further read the identifier of the rotation port, and if the identifier is the first identifier, control the rotation component 276 to rotate the display to a preset angle in the rotatable direction; if the identification is a second identification, the control display presents a prompt for the user that the rotating assembly 276 is not inserted into the rotating port.

In a possible embodiment, after determining the rotational direction, the controller may further read the state of the rotary switch;

if the rotary switch is in the chopping state, controlling a display to display prompt information, wherein the prompt information is used for prompting a user that the rotary switch is in the chopping state; if the rotary switch is in the on state, the control rotating component 276 drives the display to rotate to a preset angle in the rotatable direction.

A second aspect of the embodiments of the present application shows a display device, and the work flow of the display device can refer to fig. 14. 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 displaying the presentation page.

a controller 250 configured to perform steps S201-S204;

s201, responding to the starting of the application, reading a first display direction and a second display direction, wherein the first display direction is a display direction supported by the currently started application, and the second display direction is a current display direction of the display;

in some feasible embodiments, in response to the starting of the application, the controller 250 reads a first display direction and a second display direction, where the first display direction is a display direction supported by the currently started application, and the second display direction is a current display direction of the display 275; if the first display direction is not consistent with the second display direction, the controller 250 controls the rotating assembly 276 to rotate the display 275, so that the display direction of the rotated display 275 is consistent with the first display direction; for example, if the controller 250 detects that the current rotation angle of the display 275 is 90 degrees through the angle sensor, it may determine 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 the controller 250 detects that the current rotation angle of the display 275 is 90 degrees through the angle sensor, it may determine 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.

There are various ways to read the first/second display directions.

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

Specifically, after the action of loading the application interface is completed, the attribute value of the application interface 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 application interface by calling the resolution in the attribute value. The resolution describes the number of pixels that an application interface contains in both the "horizontal" and "vertical" dimensions. For example, the 1920 × 1080 application interface is composed of 1920 pixels in the transverse direction and 1080 pixels in the longitudinal direction (2,073,600 pixels in total). Based on the resolution, whether the display direction of the application interface is the horizontal screen display direction or the horizontal screen display direction can be obtained.

For another example, to add a direction identifier to the configuration information of the application interface, the controller 250 may obtain the configuration information of the current pull-up application 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 the first direction identifier, the display direction supported by the application interface is a horizontal screen display direction; and if the display direction identifier is the second direction identifier, the display direction supported by the application interface is the 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 application interface only supports the horizontal screen display direction, V represents that the application interface only supports the vertical screen, and HV represents that the application interface simultaneously supports the horizontal screen display direction and 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 embodiments of the present application only show several implementation manners of reading the first/second display directions by way of example, and in the process of practical application, the implementation manner of reading the first/second display directions is not limited to the above several manners.

S202, if the first display direction is not matched with the second display direction, determining that the rotating assembly does not have the condition of driving the display to rotate, and controlling the display to display prompt information;

s203, if the rotating component is determined to have the condition of driving the display to rotate, the rotating component 276 is controlled to drive the display to rotate;

In specific implementations, the present application also provides a computer storage medium, wherein the computer storage medium may store a program, and the program may include some or all of the steps in the embodiments of the method provided by the present application when executed, and when the controller 250 of the display device provided by the present application runs the computer program instructions, the controller 250 executes the steps in which the controller 250 of the present application is configured. The storage medium may be a magnetic disk, an optical disk, a read-only memory (ROM), a Random Access Memory (RAM), or the like.

Those skilled in the art will clearly understand that the techniques in the embodiments of the present application may be implemented by way of software plus a required general hardware platform. Based on such understanding, the technical solutions in the embodiments of the present application may be essentially implemented or portions thereof contributing to the prior art may be embodied in the form of a software product, which may be stored in a storage medium, such as a ROM/RAM, a magnetic disk, an optical disk, etc., and includes several instructions for enabling a computer device (which may be a personal computer, a server, or a network device, etc.) to execute the method of the embodiments or some portions thereof in the embodiments of the present application.
