Background

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

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

Detailed Description

In order to make 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 social television is a novel intelligent television and mainly comprises a display screen and a rotary component. Wherein, the display screen passes through rotatory subassembly to be connected on support or wall, and the angle is placed to the accessible rotatory subassembly regulation display screen, reaches rotatory purpose. Different display screen placement angles can accommodate displays of different aspect ratios, for example, in most cases the display screen is laterally positioned to display video pictures of movies, television shows, etc. having an aspect ratio of 16: 9. When the aspect ratio of a video picture is a picture such as a short video with a 9:16 ratio, a cartoon and the like, the horizontally placed display screen needs to be zoomed, and black areas are displayed on two sides of the display screen. Thus, the display screen can be vertically positioned by the rotating assembly to accommodate a 9:16 scaled video frame.

In order to achieve automatic rotation of the screen of the rotating social television, a driving motor is usually included in the rotating assembly. Typical driving motors are servo motors, stepping motors and the like which can directly control the rotation angle. The rotation process of the rotating social television is easily affected by factors in the environment, and a locked-rotor state occurs, namely, the rotation process of the display screen is interrupted due to power failure, foreign matters, artificial blocking and the like, and the display screen is not rotated to a preset state. For example, to protect the drive motor from damage due to overheating, if the display is manually forced to stop for more than 2 seconds during rotation, the system will automatically shut off the rotation of the drive motor. At this point, the rotating social television is in a locked state.

In general, the display screen of the rotating social television in the locked state is inclined, which directly affects the viewing experience of the user. For the traditional rotary social television, in order to overcome the inclined state, the user needs to manually restore the display screen to the normal state after finding the locked-rotor state, so that the use by the user is inconvenient. Moreover, when the inclination angle of the display screen is small, a user cannot easily find the inclination angle and cannot easily control the recovery operation, so that the display screen is in an inclined posture for a long time, and the inclination can influence the detection precision of the orientation sensor integrated in the rotary social television, and further influence the display effect. In order to improve the display effect, the application provides a display device and a locked rotor state recovery method.

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

The kernel layer provides core system services, such as: file management, memory management, process management, network management, system security authority management and the like. The kernel layer may be implemented as a kernel based on various operating systems, for example, a kernel based on the Linux operating system.

The kernel layer also provides communication between system software and hardware, and provides device driver services for various hardware, such as: provide display driver for the display, provide camera driver for the camera, provide button driver for the remote controller, provide wiFi driver for the WIFI module, provide audio driver for audio output interface, provide power management drive for Power Management (PM) module etc..

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

In some embodiments, a user may enter user commands on a Graphical User Interface (GUI) displayed on the display 275, and the user interface 265 receives the user input commands through the GUI. Specifically, the user interface 265 may receive user input commands for controlling the position of a selector in the GUI to select different objects or items. Among these, "user interfaces" are media interfaces for interaction and information exchange between an application or operating system and a user, which enable the conversion between an internal form of information and a form acceptable to the user. A commonly used presentation form of the user interface is a Graphical User Interface (GUI), which refers to a user interface related to computer operations and displayed in a graphical manner. It may be an interface element such as an icon, a window, a control, etc. displayed in the display screen of the electronic device, where the control may include a visual interface element such as an icon, a control, a menu, a tab, a text box, a dialog box, a status bar, a channel bar, a Widget, etc.

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

The display 275, while displaying a user manipulation interface UI generated in the display apparatus 200 and used to control the display apparatus 200.

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

Rotating assembly 276, the controller may issue a control signal to cause rotating assembly 276 to rotate display 255.

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

Illustratively, audio processor 280 may support various audio formats. Such as MPEG-2, MPEG-4, Advanced Audio Coding (AAC), high efficiency AAC (HE-AAC), and the like.

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

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

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

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

To enable rotation of the display area of the display device 200, the present application provides a display device 200 that includes a display 275, a rotation assembly 276, and a controller 250. The display 275 may be mounted to a wall or a stand by a rotating assembly 276. Wherein the controller 250 may control the rotation assembly 276 to rotate, thereby driving the display 275 to rotate. As shown in fig. 5, 6A, and 6B, the display 275 may be in the same posture as the rotating assembly 276 rotates, for example, the display 275 having a rectangular structure includes two long sides and two short sides, and when the two long sides of the display 275 are in a horizontal state, the display 275 is in a landscape state; when the two long sides of the display 275 are in the vertical state, the display 275 is in the portrait state.

That is, the landscape state is a state 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 state is a state 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, the vertical direction is substantially vertical in the present application, and the horizontal direction is also substantially horizontal, depending on the installation/placement position of the display device 200. The horizontal screen state is mainly used for displaying horizontal media such as a tv drama and a movie as shown in fig. 6A, and the vertical screen state is mainly used for displaying vertical media such as a short video and a cartoon as shown in fig. 6B.

It should be noted that the horizontal screen state and the vertical screen state are only two different display states, 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 state; horizontal media assets such as TV dramas and movies can still be displayed in the vertical screen state, and only the incompatible display windows need to be compressed and adjusted in the vertical screen state.

In the present application, the display states such as the landscape state and the portrait state are referred to as a standard state, and in the standard state, the display 275 can normally display a playback screen and a UI interface. For example, in the landscape state, the display 275 may display a movie, a tv show, or other landscape assets in full screen. Meanwhile, the placement posture of the display 275 other than the standard state is referred to as a locked-rotor state in the present application. As shown in fig. 5, in the locked state, the display 275 is normally tilted, and thus cannot be normally displayed or the displayed screen is tilted.

The locked state, which is an abnormal condition of the display 275, generally occurs in the case of power failure, clogging with foreign objects, human obstruction, and the like. For example, a sudden power failure during rotation of the display 275 from the landscape to the portrait position may cause the rotation assembly 276 to stop rotating, at which time the display 275 may be stuck in the tilted position, i.e., the locked position. In addition, in practical applications, it is also possible to cause the display 275 to be in a locked state by a human operation, for example, to cause the display 275 to be out of a standard state by rotating the display 275 by a human operation. Therefore, in order not to affect the viewing effect of the user, the locked state needs to be restored.

The present application is directed to the restoration of the locked state by rotating the assembly 276 to adjust the display 275 from the locked state back to the normal state. Obviously, for the locked-rotor condition caused by power failure and man-made blockage, since the problems of power failure and man-made blockage are generally solved before recovery, the recovery of the locked-rotor condition can be accomplished directly by the rotating action of the rotating component 276. However, for the locked state caused by the blockage of the foreign object, the blocked foreign object is removed and then the display 275 is rotated to the normal state by the rotating assembly 276.

Since the locked state of the display 275 may occur during power-on or during power-off, a resident service application needs to be embedded in the display device 200 for monitoring the rotation state of the display 275, and when the locked state of the display 275 is monitored, a corresponding locked state recovery program is started to adjust the rotation state of the display 275. The resident service application may automatically run along with the start of the operating system during the boot process of the display device 200, and is always in a background running state during the running process of the display device 200 after booting.

After the start-up, the controller 250 of the display device 200 may execute the control program by manual triggering or automatic triggering, and rotate the display 275 to the standard state before the media asset is formally played, so as to reduce the influence of the locked-rotor state on the viewing effect.

To restore the locked rotor state, the present application provides a display device 200, as shown in fig. 7, wherein the controller 250 in the display device 200 is configured to perform the following program steps:

s1: in response to activation of the display device, a current rotational state of the display is detected.

In the technical solution provided in the present application, the starting process refers to controlling the display device 200 to start and operate after the user performs a starting operation, for example, by pressing (touching) a start key on the control device 100; or controls the display device 200 to start the running process by pressing (touching) a power key on the display device 200. In the starting process of the display device 200, the hardware in the display device 200 is first powered on to run, and then the control homepage is accessed by executing the operating system program.

The controller 250 may detect a rotation state in which the display 275 is currently positioned in response to the activation of the display apparatus 200 after monitoring a power-on event of the display apparatus 200, thereby determining whether the display 275 is in a locked-rotor state. In a specific detection method, the posture of the display 275 with respect to a standard state or an initial position may be detected by a posture sensor built in the display 275 or an angle sensor provided in the rotary unit 276, and the rotation state of the display 275 may be determined.

S2: and if the display is in a locked-rotor state, acquiring a rotation instruction.

After detecting the current rotation state of the display 275, the controller 250 may execute different control programs according to the rotation state of the display 275. If the display 275 is in the locked state, a rotation command is obtained, wherein the rotation command is a control command actively sent by the user. In practical applications, the control device 100 may be provided with a rotation key, and the user may generate the rotation command by pressing the rotation key on the control device 100. The control device 100 may transmit the rotation command to the display device 200 by a wireless transmission method such as infrared transmission, bluetooth, or a cellular network.

The rotation instruction may also be generated by voice input, that is, the display device 200 has an intelligent voice system built therein, and a user may perform voice input through the voice system to enable the controller 250 to execute a control program corresponding to the voice. The user may input a designated calling word, such as "hi!by far-field speech! Xxx', calling an intelligent voice system input mode; or by pressing a voice input key on the control device 100, the input mode of the intelligent voice system is started. After the input mode is started, the user inputs specific words such as 'rotate' and 'rotate the screen' through voice, and a rotation instruction is triggered and generated.

S3: and controlling the rotating assembly to rotate according to the rotating instruction so as to rotate the display to a standard state.

After obtaining the rotation command, the controller 250 may parse the rotation command, extract the rotation manner specified therein, and generate a corresponding control command to control the rotation component 276 to rotate, thereby rotating the display 275 to the standard state. The standard state to which the display 275 is rotated may be specified in the rotation instruction, may be specified according to a preset locked-rotor state recovery mode, and may be automatically rotated to any standard state according to the current posture of the display 275.

To enable detection of the rotational state of the display 275, in one implementation, a gesture sensor is built into the display 275 for detecting the gesture of the display 275. Accordingly, as shown in fig. 9, in the step of detecting the current rotation state of the display 275 in response to the activation of the display device 200, the controller 250 is further configured to:

s111: and acquiring real-time attitude data detected by the attitude sensor.

In the present embodiment, the attitude sensor means a sensor capable of detecting a change in the attitude of the display 275, such as a gyroscope, a gravitational acceleration sensor, a magnetic force sensor, or the like. Since the installation position of the attitude sensor in the display 275 is fixed, the attitude of the display 275 with respect to the direction signal such as gravity can be determined by detecting the signal having the direction such as gravity, the earth magnetic field, or the like.

Taking a gravitational acceleration sensor as an example, a spatial rectangular coordinate system may be constructed according to the placement posture of the display 275. As shown in fig. 8, when the display apparatus 200 is mounted on a wall in a landscape state, the display screen of the display 275 is parallel to the wall surface by default. From the user viewing direction, the vertical upward direction is taken as an X axis, the horizontal leftward direction is taken as a Y axis, and the direction perpendicular to the outer edge of the front surface of the screen is taken as a Z axis. In response to the activation of the display apparatus 200, the controller 250 may detect components of the current gravitational acceleration in three coordinate axes in the spatial coordinate system through the gravitational acceleration sensor as real-time posture data (x, y, z) of the display 275, thereby determining a posture in which the current display 275 corresponds.

S112: and comparing the real-time attitude data with the standard attitude data to generate an attitude judgment value.

After acquiring the real-time pose data, the controller 250 may compare the real-time pose data with the standard pose data to determine a pose determination value. The standard posture data is a detection value of the posture sensor when the display 275 is in a standard state. The standard attitude data may be set according to the detection accuracy of the attitude sensor. For example, the standard attitude data is set as the components of the gravitational acceleration in the landscape state on three coordinate axes in the space coordinate system, that is, (x)₀，y₀，z₀) Then, the coordinate values in the real-time attitude data (x, y, z) can be compared with the standard attitude data (x) respectively₀，y₀，z₀) Corresponding coordinate values in (2). I.e. separately calculating attitude judgment values：Δx＝∣x-x₀∣；Δy＝∣y-y₀∣；Δz＝∣z-z₀∣。

In practical applications, since the display 275 generally rotates only in a vertical plane, for convenience of determination, the pose data may be converted into a rotation angle through a spatial geometric relationship, and the rotation angle may be compared with the angle of the initial 0-bit to generate a pose determination value.

S113: and if the gesture judgment value is larger than the maximum allowable deviation value, determining that the display is in a locked-rotor state.

After the attitude judgment value is generated, the attitude judgment value can be further judged to determine whether the attitude judgment value is larger than the maximum allowable deviation value. If the posture judgment value is larger than the maximum allowable deviation value, it indicates that the current posture of the display 275 is not within the allowable deviation range, i.e., the display 275 is inclined at a larger angle with respect to the standard state, i.e., the display 275 is in the locked state.

For example, the maximum allowable deviation value may also include that the gravity direction corresponding to the maximum deviation value is a component on three coordinate axes, for example, the maximum allowable deviation on the x axis is x'; the maximum allowable deviation on the y-axis is y'; the maximum allowed deviation in the z-axis is z'. Respectively comparing the attitude judgment value corresponding to each coordinate axis with the maximum allowable deviation, and determining the rotation state of the display 275 according to the comparison result; if Δ x ≦ x ' and Δ y ≦ y ' and Δ z ≦ z ', then it is determined that the display 275 is in the normal state; if the component on either coordinate axis is greater than the maximum allowable deviation, i.e., Δ x > x ', or Δ y > y ', or Δ z > z ', then it is determined that the display 275 is currently in the stalled state.

In this embodiment, the maximum allowable deviation value may be set according to the detection accuracy of the attitude sensor. Moreover, since the display 275 is inclined at a small angle in practical use, for example, 0-3 degrees will not have a large influence on the viewing effect of the user. Therefore, for a common household display device 200, especially a small screen (65 inches or less) display device 200, the maximum allowable deviation value can be properly relaxed to accommodate the return deviation of the rotating assembly 276 and the influence of fluctuations in the environment, and avoid too frequent rotation correction of the display 275.

In one implementation, an angle sensor is disposed on the rotating component 276, and the angle sensor is used for detecting the rotation angle of the rotating component. The angle sensor can be any angle sensor capable of meeting the detection precision requirement, such as a grating angle sensor, an electromagnetic angle sensor, a sliding resistor and the like. The rotation angle of the display 275 with respect to the initial 0 position can be directly detected by the angle sensor, facilitating subsequent calculations. Thus, as shown in fig. 10, the controller 250 is further configured to:

s121: and acquiring the rotation angle detected by the angle sensor.

The angle sensor may directly detect the angle of the current rotating assembly 276. In practice, the initial 0-position angle of the angle sensor can be determined according to any standard state. For example, the angle value detected by the angle sensor in the landscape state is set to the initial 0-position angle. Based on the initial 0-position angle, the relative rotation angle of the angle sensor in other rotation states, for example, the vertical screen state is rotated by +90 degrees or-90 degrees relative to the initial 0-position angle. Therefore, in the present embodiment, the rotation angle detected by the angle sensor may be an angle difference with respect to the initial 0-position angle.

S122: and comparing the rotation angle with the standard angle to generate an angle judgment value.

After obtaining the current rotation angle of the rotating assembly 276 from the angle sensor, the controller 250 may further calculate an angle judgment value by comparing the rotation angle with a preset standard angle. And the standard angle is the angle detected by the angle sensor when the display is in the standard state.

The standard state can be in various forms such as a horizontal screen state and a vertical screen state, so that the standard angle also has a plurality of angle values. For example, the corresponding standard angle in the horizontal screen state is 0 degree; the corresponding standard angle in the vertical screen state is 90 degrees. Therefore, in practical application, the rotation angle can be compared with a plurality of standard angles respectively to determine a plurality of angle judgment values. For example, rotation detected by an angle sensorWhen the dynamic angle is 30 degrees, the generated angle judgment value is r₁-30-0 ═ 30 degrees; r is₂-30-90-60 degrees.

S123: and if the angle judgment value is larger than the maximum error angle, determining that the display is in a locked-rotor state.

After the angle judgment value is generated, the generated angle judgment value may be compared with the maximum error angle, respectively, to determine the rotation state of the display 275. Since there are a plurality of angle determination values, in practical applications, if any one of the angle determination values is smaller than the maximum error angle, it is determined that the current display 275 is in the standard state.

For example, if the maximum error angle is set to 3 degrees and the current rotation angle is 1.2 degrees, the angle determination value r is set to be the maximum error angle₁1.2-0 | -1.2 degrees is less than the maximum error angle; and the angle judgment value r₂I 1.2-90 | 88.8 degrees is greater than the maximum error angle, it is determined that the display 275 is in the landscape state, which is the normal state.

The spin instructions of the present application may be used to instruct the controller 250 to run a control program that controls the spin assembly 276 to initiate spinning. According to different interaction modes of the display device 200, the input rotation instruction may be different, for example, a user may perform an operation on a control on a UI interface to generate a rotation instruction; a rotation instruction can also be generated by a rotation key on the control device 100; and a rotation related password can be input through the intelligent voice system to generate a rotation instruction.

In one implementation, the rotation instructions include directional instructions and non-directional instructions. The directional instruction is a rotation instruction containing a rotation target standard state, for example, a user inputs a rotation to vertical screen state through an intelligent voice system, that is, the input rotation instruction contains the rotation target standard state as the vertical screen state; the non-directional instruction is a rotation instruction not containing a rotation target standard state, for example, a user inputs "rotation" through the intelligent voice system, that is, the input rotation instruction does not contain the rotation target standard state.

As shown in fig. 11, if the rotation instruction is a directional instruction, the controller 250 is further configured to:

s311: extracting a first target state specified in the rotation instruction;

s312: rotating the display to the first target state.

When the rotation command is a directional command, the directional command includes a target state to which the display is to be rotated, so that the rotation member 276 can be controlled to rotate the display 275 to the corresponding target state.

For example, the current locked-rotor state is detected as: the display 275 is in the 30-degree inclined state, the rotation instruction input by the user is "rotate to vertical screen state", that is, the first target state is the vertical screen state of 90 degrees, at this time, by calculating that the angle difference between the current locked-rotor state and the vertical screen state is 60 degrees, the controller 250 controls the rotating assembly 276 to rotate 60 degrees counterclockwise, and the display 275 can be rotated to vertical screen state.

In practice, after determining the target state, the controller 250 may only instruct the rotating component 276 to rotate in the direction toward the target state, and in a different standard state, a physical method such as a limit switch may be used to force the rotating component 276 to stop rotating after the display 275 rotates to the target state, so that the display 275 rotates to the corresponding target state. For example, if the user inputs a rotation command "rotate to the portrait state", the controller 250 controls the rotating assembly 276 to rotate counterclockwise until the display 275 rotates to the portrait state.

However, in practical applications, some users may not use the voice system to input explicit executive instructions, or directly press the rotation key of the control device 100, that is, the input rotation instructions are non-directional instructions. Thus, as shown in fig. 12, if the rotation instruction is a non-directional instruction, the controller 250 is further configured to:

s321: acquiring a recording instruction;

s322: extracting a second target state specified in the recording instruction;

s323: controlling a rotation component to rotate the display to the second target state.

And the recording instruction is a rotation instruction recorded when the locked-rotor state is triggered last time by the display equipment. In the present embodiment, a background program may be configured as a default in the display device 200 to record the rotation instruction of the user. In the process of recovering the display 275 from the locked state, if the user inputs a non-directional instruction, the target state to which the user wants to rotate in the last rotation process can be determined according to the recording instruction by acquiring the recording instruction. In accordance with the same calculations as in the previous embodiment, the rotation assembly 276 is controlled to rotate the display 275 to the second target state.

For example, the current locked-rotor state is detected as: the display 275 is in a tilted state of 30 degrees. If the user presses the "rotation key" on the control device 100 or the user inputs "rotation" by voice, the rotation command is a non-directional command. At this time, after receiving the rotation command, the controller 250 obtains a recording command from the memory of the display device 200. If the recording command is "rotate from the vertical screen state to the horizontal screen state", that is, the second target state is the horizontal screen state (0 degree). After calculating the angle difference between the current locked-rotor state and the second target state to be 30 degrees, the rotating assembly 276 may be controlled to rotate clockwise by 30 degrees to rotate the display to the landscape state.

In some cases, the rotation instruction of the last rotation process may not be recorded in the display device 200, and therefore, in one implementation, as shown in fig. 13, if the rotation instruction is a non-directional instruction, the controller 250 is further configured to:

s331: calculating the angle difference between the current locked rotor state and all standard states, and determining a third target state;

s332: controlling a rotation component to rotate the display to the third target state.

And the third target state is a standard state with the smallest angle difference with the current locked rotor state. And if the rotation instruction is a non-directional instruction, determining the standard state with the smallest angle difference with the current locked-rotor state as the target state by calculating the angle difference between the current locked-rotor state and all the standard states. The display 275 is rotated to the target state in accordance with the rotation control method of the above embodiment.

For example, the current locked-rotor state is detected as: the display 275 is in a tilted state of 30 degrees. If the rotation instruction is a non-directional instruction, the angular differences between the current locked-rotor state and the horizontal screen state (0 degrees) and the vertical screen state (90 degrees), namely 30 degrees and 60 degrees respectively, are calculated. At this time, it may be determined that the angle difference between the current locked-rotor state and the landscape state is the smallest, and it is determined that the landscape state is the third target state, and thus, the rotating assembly 276 may be controlled to rotate clockwise by 30 degrees to rotate the display 275 to the landscape state.

In one implementation, as shown in fig. 14, the controller 250 is further configured to:

s401: if the display is in a standard state, controlling the display to display a homepage corresponding to the standard state;

s402: acquiring the rotation instruction;

s403: and controlling the rotating component to rotate according to the rotating instruction so as to rotate the display to a standard state specified in the rotating instruction.

If the display 275 is in the standard state, the control homepage corresponding to the standard state can be normally presented after the power-on is started. For example, as shown in fig. 6A, upon determining that the display 275 is in the landscape state, the controller 250 may control the display 275 to present a landscape home page corresponding to the landscape state. Controller 250 may also interact with server 300 in order to present a landscape home page. That is, while the display 275 is in the landscape state, the controller 250 transmits a landscape home page data request to the server 300 in response to the activation of the display apparatus 200. And receives the landscape home page data fed back by the server 300 in response to the landscape home page data request; and then controls the display 275 to display the landscape home page based on the landscape home page data.

While the home page is displayed, the controller 250 may also retrieve a rotation instruction to control the rotation of the rotation assembly 276 according to the rotation instruction to rotate the display 275 to a standard state specified in the rotation instruction. For example, the current rotation state of the display 275 is the landscape state, and the user inputs a rotation command by operating a rotation key on the apparatus 100, and the controller 250 controls the rotating assembly 276 to rotate clockwise by 90 degrees, thereby rotating the display 275 to the portrait state.

Based on the above display device, as shown in fig. 8, the present application further provides a locked rotor state recovery method, including:

s1: detecting a current rotation state of the display in response to activation of a display device; the rotation state comprises a standard state and a locked-rotor state; the locked-rotor state is any intermediate state of the display in the switching process under two standard states;

s2: if the display is in a locked-rotor state, a rotation instruction is acquired; the rotation instruction is a control instruction actively sent by a user;

As can be seen from the above technical solutions, the controller 250 of the display device 200 provided in the above embodiments may detect the current rotation state of the display 275 in response to the activation of the display device 200; if the display 275 is in the locked state, a rotation command is obtained and the rotation of the rotating assembly 276 is controlled according to the rotation command to rotate the display 275 to the normal state. Wherein the rotation instruction is a control instruction actively sent by a user. In the case where the display 275 is in the locked state, the user may control the rotation of the rotating member 276 by key operation, voice operation, or the like, and automatically adjust the rotation state of the display 275 so as to return from the locked state to the normal state.

In the above embodiment, after determining that the display 275 is in the locked state, the user is required to actively input a rotation instruction in order to recover from the locked state. However, in some cases, the user does not input a rotation command, for example, the user does not find the locked state of the display 275 because the tilt angle is small. Such a situation will cause the display apparatus 200 to be in the locked-rotor state for a long time, will affect the detection accuracy of the orientation sensor in the display apparatus 200, and will affect the display control accuracy. To alleviate this, another embodiment of the present application further provides a display device 200, including: a display 275, a rotation assembly 276, and a controller 250, wherein the rotation assembly 276 is configured to rotate the display 275 such that the display 275 is in different rotational states; the rotation state comprises a standard state and a locked-rotor state; the locked state is any intermediate state of the display 275 in the switching process between the two standard states.

Also, as shown in fig. 15, the controller 250 is configured to execute the following program steps:

s5: detecting a current rotation state of the display in response to activation of a display device;

s6: if the display is in a locked-rotor state, acquiring a starting application type;

s7: controlling the rotation component to rotate according to the type of the started application so as to rotate the display to a standard state.

In this embodiment, after determining that the display 275 is in the locked state, the locked state of the display 275 may be automatically recovered by obtaining the type of the application started by the user. The standard state comprises a horizontal screen state and a vertical screen state; the starting application type comprises a first type of application only supporting a landscape state, such as a live television application, a movie and television application and the like; a second type of application that supports only the portrait state, such as a short video application, a comic application, etc., and a third type of application that supports both the landscape state and the portrait state, such as a browser application, etc.

In one implementation, as shown in fig. 16, if the launch application type is a first type application or a second type application, the controller 250 is further configured to:

s711: extracting an application support state in the starting application type;

s712: controlling a rotation component to rotate the display to the application support state.

If the type of the launched application is a first type of application or a second type of application, the controller 250 may extract a state supported by the launched application, i.e., a standard state supported by the launched application. And then rotated by controlling the rotation component 276 to rotate the display 275 to a state supported by the launched application.

For example, when the display 275 is in the locked state and the user starts the live tv application through the control device 100 or starts the live tv application through the voice system, the controller 250 may determine the horizontal and vertical screen states supported by the live tv application after receiving the application instruction. Obviously, the live tv application only supports the landscape state, the display 275 is rotated to the landscape state and a live tv picture is presented.

In one implementation, if the launch application type is a third type of application, the controller 250 is further configured to:

s721: acquiring a recording instruction;

s722: extracting a fourth target state specified in the recording instruction;

s723: controlling a rotation component to rotate the display to the fourth target state.

And the recording instruction is a rotation instruction recorded when the locked-rotor state is triggered last time by the display equipment. In the same manner as the above-described embodiment, in which the rotation instruction is a non-directional instruction, when the application type of the start application is the third type application, the target state may be determined by recording the instruction, and the display 275 may be rotated to the target state by controlling the rotation member 276 to rotate by the angle difference.

For example, if the application started by the user is a browser application supporting both the landscape state and the portrait state, the controller 250 may first obtain a previous rotation instruction, for example, rotate from the portrait state to the landscape state, determine that the rotation direction is clockwise rotation, then rotate the display 275 to the corresponding standard state according to the clockwise rotation direction, and start the browser application.

s731: calculating the angle difference between the current locked rotor state and all standard states, and determining a fifth target state;

s732: controlling a rotation component to rotate the display to the fifth target state.

And the fifth target state is a standard state with the smallest angle difference with the current locked rotor state. Similarly, the present embodiment may also determine the target state by calculating the angle difference between the current locked rotor state and all the standard states. And controls the rotation assembly 276 to rotate the display 275 to the target state.

Note that when the display 275 rotates from the locked state to the standard state, a rotation animation may be added as a transition screen at the time of rotation. For example, during rotation, if application switching is involved, a rotation animation occlusion application switching process may be added; if the application launched is an application that supports both landscape and portrait states, the spin animation may not be displayed because the system framework itself will spin the application interface when the display 275 turns to a certain degree.

Based on the display device 200, as shown in fig. 13, the present application further provides a locked rotor state recovery method, including:

s5: detecting a current rotation state of the display in response to activation of a display device; the rotation state comprises a standard state and a locked-rotor state; the locked-rotor state is any intermediate state of the display in the switching process under two standard states;

As can be seen from the above technical solutions, the present application provides a display device and a locked-rotor state recovery method, where the controller 250 of the display device 200 may detect a current rotation state of the display 275 in response to the start-up of the display device 200; if the display 275 is in a locked-rotor state, the type of the application to be started is obtained; the rotation of the rotating member 276 is controlled according to the type of the start-up application to rotate the display 275 to a normal state. For the case where the display 275 is in the locked state, the controller 250 may automatically adjust the rotational state of the display 275 by starting the application type, determining a standard state supported by the started application, and rotating the display 275 to the standard state supported by the started application to restore the locked state to the standard state.
