Detailed ways

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

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

In order to automatically rotate the screen of the rotating social TV, the rotating assembly usually includes a driving motor. Typical drive motors are servo motors, stepping motors, and other motors that can directly control the angle of rotation. The rotating process of the rotating social TV is easily affected by environmental factors, and a locked-rotor state occurs, that is, the rotating process of the display screen is interrupted due to power failure, foreign objects, and man-made obstructions, instead of rotating to a predetermined state. For example, in order to protect the drive motor from overheating and damage, if the display screen is forced to stop for more than 2 seconds during the rotation process, the system will automatically cut off the rotation of the drive motor. At this time, the rotating social TV is in a stalled state.

Generally, the display screen of a rotating social TV in a stalled state is tilted, which directly affects the user's viewing experience. For traditional rotating social TVs, in order to overcome the tilted state, the user needs to manually restore the display to the normal state after discovering the stalled state, which is inconvenient for the user to use. Moreover, when the tilt angle of the display screen is small, it is difficult for the user to notice and control the recovery operation, which causes the display screen to be in a tilted posture for a long time. This tilt will affect the detection accuracy of the orientation sensor integrated in the rotating social TV. Affect the display effect. In order to improve the display effect, the present application provides a display device and a method for restoring a locked-rotor state.

It can be an icon, window, control and other interface elements displayed on the display screen of an electronic device. The control can include icons, controls, menus, tabs, text boxes, dialog boxes, status bars, channel bars, Widgets, etc. Visual interface elements.

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

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

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

Among them, the demultiplexing module is used to demultiplex the input audio and video data stream, such as the input MPEG-2 stream (based on the compression standard of digital storage media moving images and voice), then the demultiplexing module will demultiplex it Multiplexed into video signals and audio signals, etc.

The video decoding module is used to process the demultiplexed video signal, including decoding and scaling.

An image synthesis module, such as an image synthesizer, is used to superimpose and mix the GUI signal generated by the graphics generator with the zoomed video image according to the user input or itself, so as to generate an image signal for display.

The frame rate conversion module is used to convert the frame rate of the input video, such as converting the frame rate of the input 60Hz video to a frame rate of 120Hz or 240Hz, and the usual format is realized by such as frame interpolation.

The display formatting module is used to change the signal output by the frame rate conversion module to a signal conforming to the display format such as a display, for example, format the signal output by the frame rate conversion module to output RGB data signals.

The display 275 is used to receive the image signal input from the video processor 270 to display video content, images, and a menu control interface. The displayed video content can be from the video content in the broadcast signal received by the tuner and demodulator 210, or from the video content input by the communicator 220 or the external device interface 240. The display 275 simultaneously displays a user manipulation interface UI generated in the display device 200 and used to control the display device 200.

And, the display 275 may include a display screen component for presenting a picture and a driving component for driving image display. Alternatively, if the display 275 is a projection display, it may also include a projection device and a projection screen.

Rotating the component 276, the controller can send a control signal to make the rotating component 276 rotate the display 255.

The audio processor 280 is used to receive external audio signals, and perform decompression and decoding according to the standard codec protocol of the input signal, as well as audio data processing such as noise reduction, digital-to-analog conversion, and amplification processing, so that it can be stored in the speaker 286 The audio signal to be played.

Exemplarily, the audio processor 280 may support various audio formats. Such as MPEG-2, MPEG-4, Advanced Audio Coding (AAC), High Efficiency AAC (HE-AAC) and other formats.

The audio output interface 285 is used to receive the audio signal output by the audio processor 280 under the control of the controller 250. The audio output interface 285 may include a speaker 286, or output to an external audio output terminal 287 of a generator of an external device, such as a headset Output terminal.

In some other exemplary embodiments, the video processor 270 may include one or more chips. The audio processor 280 may also include one or more chips.

And, in some 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.

The power supply 290 is used to provide power supply support for the display device 200 with power input from an external power supply under the control of the controller 250. The power supply 290 may be a built-in power supply circuit installed inside the display device 200, or may be a power supply installed outside the display device 200.

In order to realize the rotation of the display area of the display device 200, the display device 200 provided in the present application includes a display 275, a rotation component 276, and a controller 250. The display 275 can be installed on a wall or a bracket through the rotating assembly 276. Wherein, the controller 250 can control the rotating assembly 276 to rotate, thereby driving the display 275 to rotate. As shown in Figures 5, 6A, and 6B, as the rotating assembly 276 rotates, the display 275 will be in the same posture. For example, the display 275 with a rectangular structure includes two long sides and two short sides. When the two long sides are in a horizontal state, the display 275 is in a horizontal screen state; when the two long sides of the indicator 275 are in a vertical state, the display 275 is in a vertical screen state.

That is, the horizontal screen state refers to a state in which the length (width) in the horizontal direction of the display 275 is greater than the length (height) in the vertical direction when viewed from the front of the display 275; When the display 275 is viewed from the front, the length (width) of the display 275 in the horizontal direction is smaller than the length (height) in the vertical direction. Obviously, affected by the installation/placement position of the display device 200, the vertical direction in the present application refers to substantially vertical, and the horizontal direction also refers to substantially horizontal. The horizontal screen state is mainly used to display horizontal media assets such as TV series and movies, as shown in Figure 6, and the vertical screen state is mainly used to display vertical media assets such as short videos and comics, as shown in Figure 7.

It should be noted that the above-mentioned horizontal screen state and vertical screen state are just two different display states and do not limit the displayed content. For example, vertical media assets such as short videos and comics can still be displayed in the horizontal screen state; Horizontal media assets such as TV series and movies can still be displayed in the vertical screen state, but the inconsistent display windows need to be compressed and adjusted in this state.

In this application, the aforementioned display states such as the horizontal screen state and the vertical screen state are referred to as the standard state. In the standard state, the display 275 can normally display the playback screen and the UI interface. For example, in the horizontal screen state, the display 275 can display horizontal screen media assets such as movies and TV shows in full screen. Meanwhile, in this application, the placement posture of the display 275 other than the standard state is referred to as the locked-rotor state. As shown in FIG. 5, in the locked state, the display 275 is usually tilted, so it cannot be displayed normally or the displayed picture is tilted.

The locked-rotor state is an abnormal condition of the display 275, which usually occurs in the case of power failure, foreign object blockage, artificial blockage, and the like. For example, a sudden power failure during the process of rotating the display 275 from the horizontal screen state to the vertical screen state causes the rotating assembly 276 to stop rotating. At this time, the display 275 will stagnate in a tilted state, that is, a locked state. In addition, in practical applications, it is also possible that the display 275 is in a locked-rotation state due to manual operation, for example, the display 275 is artificially rotated to make the display 275 out of the standard state. Therefore, in order not to affect the user's viewing effect, the locked-rotor state needs to be restored.

The restoration of the locked-rotor state in this application is to adjust the display 275 from the locked-rotor state to the standard state through the rotating assembly 276. Obviously, for the locked-rotor state caused by power outage and man-made blocking, since the problems of power outage and man-made blocking will generally be solved before restoration, the locked-rotor state can be completed directly through the rotating action of the rotating assembly 276. Recovery. However, for the locked-rotor state formed by the blockage of foreign matter, the blocked foreign matter needs to be removed first, and then the display 275 is rotated to the standard state through the rotating assembly 276.

Since the locked-rotor state of the display 275 may occur when it is turned on or when it is turned off, a resident service application needs to be built in the display device 200 to monitor the rotation state of the display 275. When it is monitored that the display 275 is in In the locked-rotor state, the corresponding locked-rotor state recovery program is started to adjust the rotation state of the display 275. Among them, the resident service application can automatically run with the startup of the operating system during the startup process of the display device 200, and will always be in a background running state during the operation of the display device 200 after startup.

After booting up, the controller 250 of the display device 200 can manually or automatically trigger a control program to rotate the display 275 to a standard state before the media is officially played, so as to reduce the influence of the locked-rotor state on the viewing effect.

In order to restore the locked rotor state, the present application provides a display device 200. As shown in FIG. 7, the controller 250 in the display device 200 is configured to execute the following program steps:

S1: In response to the startup of the display device, detect the current rotation state of the display.

In the technical solution provided in this application, the booting process refers to after the user performs a booting operation, such as by pressing (touching) the boot button on the control device 100 to control the display device 200 to start running; or by pressing (touching) the display The power button on the device 200 controls the startup process of the display device 200. During the startup process of the display device 200, the hardware in the display device 200 is powered on first, and then enters the control homepage by executing the operating system program.

The controller 250 may detect the current rotation state of the display 275 in response to the startup of the display device 200 after monitoring the power-on event of the display device 200, so as to determine whether the display 275 is in a locked state. The specific detection method can detect the posture of the display 275 relative to the standard state or the initial position through the built-in posture sensor in the display 275 or the angle sensor set on the rotation component 276 to determine the rotation state of the display 275.

S2: If the display is in a locked-rotor state, obtain a rotation instruction.

After detecting the current rotation state of the display 275, the controller 250 can execute different control programs according to the rotation state of the display 275. If the display 275 is in a locked-rotor state, a rotation instruction is obtained, where the rotation instruction is a control instruction actively sent by the user. In practical applications, the control device 100 may be provided with a rotation key, and the user can generate a rotation instruction by pressing the rotation key on the control device 100. In addition, the control device 100 may also send the rotation instruction to the display device 200 through wireless transmission methods such as infrared transmission, Bluetooth, and cellular network.

The rotation instruction can also be generated by voice input, that is, the display device 200 has a built-in intelligent voice system, and the user can perform voice input through the voice system, so that the controller 250 can execute the control program corresponding to the voice. The user can call the input mode of the intelligent voice system by inputting a designated outgoing word through far-field voice, such as "Hi! ××"; or by pressing the voice input key on the control device 100, the input mode of the intelligent voice system can be activated. After the input mode is activated, the user then enters a specific word by voice, such as "rotate" and "rotate screen", which triggers the generation of a rotation instruction.

S3: Control the rotation of the rotation component according to the rotation instruction to rotate the display to a standard state.

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

In order to detect the rotation state of the display 275, in an implementation manner, a posture sensor is built in the display 275, and the posture sensor is used to detect the posture of the display 275. Therefore, 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: Acquire real-time posture data detected by the posture sensor.

In this embodiment, the posture sensor refers to a sensor that can detect the posture change of the display 275, such as a gyroscope, a gravity acceleration sensor, a magnetic sensor, and so on. Since the installation position of the posture sensor in the display 275 is fixed, the posture of the display 275 relative to the directional signals such as gravity can be determined by detecting signals with directions such as gravity and the geomagnetic field.

Taking the gravity acceleration sensor as an example, a spatial rectangular coordinate system can be constructed according to the placement posture of the display 275. As shown in FIG. 8, when the display device 200 is installed on a wall in a landscape mode, the display screen of the display 275 is parallel to the wall by default. From the user's viewing direction, the vertical upward direction is used as the X axis, the horizontal left direction is used as the Y axis, and the direction perpendicular to the outside of the front of the screen is used as the Z axis. In response to the activation of the display device 200, the controller 250 can detect the components of the current gravitational acceleration on the three coordinate axes in the space coordinate system through the gravitational acceleration sensor as the real-time posture data (x, y, z) of the display 275, thereby It is determined that the current display 275 corresponds to the posture.

S112: Compare the real-time posture data with the standard posture data, and generate a posture judgment value.

After acquiring the real-time posture data, the controller 250 may compare the real-time posture data with the standard posture data to determine the posture judgment value. Wherein, the standard posture data is the detection value of the posture sensor when the display 275 is in the standard state. The standard posture data can be set according to the detection accuracy of the posture sensor. For example, the set standard posture data is the components of the acceleration of gravity on the three coordinate axes in the space coordinate system in the horizontal screen state, namely (x0, y0, z0), and the real-time posture data (x, y) can be compared respectively. Each coordinate value in z) corresponds to the coordinate value in the standard posture data (x0, y0, z0). That is to calculate the posture judgment value separately: Δx=∣x-x0∣; Δy=∣y-y0∣; Δz=∣z-z0∣.

In practical applications, since the display 275 generally only rotates in a vertical plane, in order to facilitate judgment, the posture data can also be converted into a rotation angle through a spatial geometric relationship, and the rotation angle can be compared with the initial zero angle. Generate attitude judgment value.

S113: If the attitude judgment value is greater than the maximum allowable deviation value, it is determined that the display is in a locked-rotor state.

After the posture judgment value is generated, the posture judgment value can be further judged to determine whether it is greater than the maximum allowable deviation value. If the posture judgment value is greater than the maximum allowable deviation value, it means that the current posture of the display 275 is not within the allowable deviation range, that is, the display 275 has a large angle tilt relative to the standard state, that is, the display 275 is in a locked state.

For example, the maximum allowable deviation value may also include the components of the gravity direction corresponding to the maximum deviation value on the 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'; z The maximum allowable deviation on the axis is z'. Then compare the posture judgment value corresponding to each coordinate axis and the maximum allowable deviation, and determine the rotation state of the display 275 through the comparison result; if Δx≤x' and Δy≤y' and Δz≤z', it is determined that the display 275 is at Standard state; if the component on any coordinate axis is greater than the maximum allowable deviation, that is, Δx>x' or Δy>y' or Δz>z', it is determined that the display 275 is currently in a locked-rotor state.

In this embodiment, the maximum allowable deviation value can be set according to the detection accuracy of the attitude sensor. In addition, since the display 275 is tilted at a relatively small angle during practical application, such as 0-3 degrees, it will not have a significant impact on the user's viewing effect. Therefore, for ordinary household display devices 200, especially display devices 200 with small screens (under 65 inches), the maximum allowable deviation can be appropriately relaxed to adapt to the return deviation of the rotating assembly 276 and the impact of fluctuations in the environment, and to avoid impact on the display 275. Perform too frequent rotation corrections.

In an implementation manner, an angle sensor is provided on the rotating component 276, and the angle sensor is used to detect the rotation angle of the rotating component. The angle sensor can be any form of angle sensor that can meet the detection accuracy requirements, such as a grating angle sensor, an electromagnetic angle sensor, a sliding resistor, and the like. The angle sensor can directly detect the rotation angle of the display 275 relative to the initial 0 position, which is convenient for subsequent calculations. Therefore, as shown in FIG. 10, the controller 250 is further configured to:

S121: Acquire the rotation angle detected by the angle sensor.

The angle sensor can directly detect the angle corresponding to the current rotating component 276. In practical applications, the initial 0-position angle of the angle sensor can be determined according to any standard state. For example, set the angle value detected by the angle sensor in the landscape mode to the initial 0-position angle. Based on the initial 0-position angle, the angle sensor can detect the relative rotation angle in other rotation states. For example, the vertical screen state is a rotation of +90 degrees or -90 degrees relative to the initial 0-position angle. Therefore, in this embodiment, the rotation angle detected by the angle sensor may be the angle difference with respect to the initial zero angle.

S122: Compare the rotation angle with the standard angle, and generate an angle judgment value.

After acquiring the current rotation angle of the rotating component 276 from the angle sensor, the controller 250 may also calculate the angle judgment value by comparing the rotation angle with a preset standard angle. Wherein, the standard angle is the angle detected by the angle sensor when the display is in a standard state.

Since the standard state can have multiple forms such as horizontal screen state and vertical screen state, the standard angle also has multiple angle values. For example, the corresponding standard angle in the horizontal screen state is 0 degrees; the corresponding standard angle in the vertical screen state is 90 degrees. Therefore, in practical applications, the rotation angle can be compared with multiple standard angles to determine multiple angle judgment values. For example, if the rotation angle detected by the angle sensor is 30 degrees, the generated angle judgment value is r1=∣30-0∣=30 degrees; r2=∣30-90∣=60 degrees.

S123: If the angle judgment value is greater than the maximum error angle, it is determined that the display is in a locked-rotor state.

After the angle judgment value is generated, the generated angle judgment value can be compared with the maximum error angle to determine the rotation state of the display 275. Since there are multiple angle judgment values, in practical applications, if any angle judgment value is less than the maximum error angle, it is judged that the current display 275 is in a 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 judgment value r1=∣1.2-0∣=1.2 degrees is less than the maximum error angle; and the angle judgment value r2=∣1.2-90∣=88.8 When the degree is greater than the maximum error angle, it is determined that the display 275 is in the horizontal screen state in the standard state.

The rotation instruction of the present application can be used to instruct the controller 250 to run a control program and control the rotation component 276 to start rotation. Depending on the interaction mode of the display device 200, the input rotation instruction can also be different. For example, the user can operate the control on the UI interface to generate a rotation instruction; it can also generate a rotation instruction through the rotation button on the control device 100; Input the password related to the rotation through the intelligent voice system to generate the rotation instruction.

In an implementation manner, the rotation instruction includes a directional instruction and a non-directional instruction. Wherein, the directivity instruction is a rotation instruction that includes the standard state of the rotation target. For example, the user inputs "rotate to portrait state" through an intelligent voice system, that is, the input rotation instruction includes the standard state of the rotation target as "portrait state". The non-directional instruction is a rotation instruction that does not include the standard state of the rotation target, for example, the user inputs "rotation" through an intelligent voice system, that is, the input rotation instruction does not include the standard state of the rotation target.

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

S311: Extract the first target state specified in the rotation instruction;

S312: Rotate the display to the first target state.

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

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

In practical applications, after determining the target state, the controller 250 can only issue an instruction to the rotating component 276 to rotate in the direction of the target state, and in different standard states, physical methods such as limit switches can be used to force the rotating component 276 to rotate in the direction of the target state. After the display 275 rotates to the target state, the rotation is stopped so that the display 275 rotates to the corresponding target state. For example, if the rotation instruction input by the user is "rotate to the vertical screen state", the controller 250 controls the rotation component 276 to rotate counterclockwise until the display 275 rotates to the vertical screen state.

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

S321: Obtain a record instruction;

S322: Extract the second target state specified in the recording instruction;

S323: Control the rotation component to rotate the display to the second target state.

Wherein, the recording instruction is a rotation instruction recorded by the display device when the locked-rotor state was triggered last time. This embodiment is more suitable for a locked-rotor state caused by a power failure. In the display device 200, a background program may be configured by default for recording the user's rotation instruction. When the display 275 recovers from the locked-rotor state, if the user inputs a non-directional instruction, the recording instruction can be obtained to determine the target state that the user wants to rotate to during the last rotation according to the recording instruction. Then, according to the same calculation method in the foregoing embodiment, the rotating component 276 is controlled to rotate the display 275 to the second target state.

For example, the detection of the current locked-rotor state is: the display 275 is in a 30-degree tilt state. The user presses the “rotation key” on the control device 100 or the user inputs “rotation” by voice, and the rotation instruction is a non-directional instruction. At this time, after receiving the rotation instruction, the controller 250 will obtain the recording instruction from the memory of the display device 200. For example, the recording instruction is "rotate from the vertical screen state to the horizontal screen state", that is, the second target state is the horizontal screen state (0 degrees). When the angle difference between the current locked rotor state and the second target state is calculated to be 30 degrees, the rotating component 276 can be controlled to rotate 30 degrees clockwise to rotate the display to the landscape state.

In some cases, the display device 200 may not record the rotation command of the last rotation process. Therefore, in one implementation, as shown in FIG. 13, if the rotation command is a non-directional command, the controller 250 is further Configured as:

S331: Calculate the angle difference between the current locked-rotor state and all standard states, and determine the third target state;

S332: Control the rotating component to rotate the display to the third target state.

Wherein, the third target state is a standard state with the smallest angle difference from the current locked rotor state. If the rotation command is a non-directional command, by calculating the angle difference between the current locked-rotor state and all standard states, the standard state with the smallest angle difference from the current locked-rotor state is determined as the target state. Then, according to the rotation control method in the above embodiment, the display 275 is rotated to the target state.

For example, the detection of the current locked-rotor state is: the display 275 is in a 30-degree tilt state. If the rotation command is a non-directional command, the angle difference between the current locked-rotor state and the horizontal screen state (0 degrees) and the vertical screen state (90 degrees) is calculated respectively, that is, 30 degrees and 60 degrees, respectively. At this time, it can be determined that the angle difference between the current locked-rotor state and the horizontal screen state is the smallest, and the horizontal screen state is determined to be the third target state. Therefore, the rotating assembly 276 can be controlled to rotate 30 degrees clockwise to rotate the display 275 to the horizontal screen. state.

In an implementation manner, as shown in FIG. 14, the controller 250 is further configured to:

S401: If the display is in a standard state, control the display to display the homepage corresponding to the standard state;

S402: Obtain the rotation instruction;

S403: Control the rotation of the rotation component according to the rotation instruction, so as to rotate the display to a standard state specified in the rotation instruction.

If the display 275 is in the standard state, it can normally display the control homepage corresponding to the standard state after being powered on. For example, as shown in FIG. 6, when it is determined that the display 275 is in the landscape state, the controller 250 may control the display 275 to present the landscape homepage corresponding to the landscape state. In order to present the horizontal screen homepage, the controller 250 may also interact with the server 300. That is, when the display 275 is in the landscape state, in response to the activation of the display device 200, the controller 250 sends a landscape homepage data request to the server 300. And receive the horizontal screen homepage data fed back by the server 300 in response to the horizontal screen homepage data request; then according to the horizontal screen homepage data, control the display 275 to display the horizontal screen homepage.

While displaying the homepage, the controller 250 may also obtain a rotation instruction, thereby controlling the rotation of the rotation component 276 according to the rotation instruction, so as 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 horizontal screen state, and the user inputs a rotation command by operating the rotation key on the device 100. At this time, the controller 250 controls the rotating component 276 to rotate 90 degrees clockwise to rotate the display 275 to the vertical screen state. .

Based on the above display device, as shown in FIG. 8, this application also provides a method for restoring a locked rotor state, including:

S1: In response to the activation of the display device, detect the current rotation state of the display; the rotation state includes a standard state and a locked-rotor state; the locked-rotor state is any of the display switches between the two standard states An intermediate state

S2: If the display is in a locked-rotor state, obtain a rotation instruction; the rotation instruction is a control instruction actively sent by the user;

S3: Control the rotation of the rotating assembly according to the rotation instruction to rotate the display to a standard state.

It can be seen from the above technical solutions that the controller 250 of the display device 200 provided in the above embodiment can detect the current rotation state of the display 275 in response to the startup of the display device 200; The rotation component 276 is commanded to rotate to rotate the display 275 to a standard state. Among them, the rotation command is a control command sent actively by the user. Regarding the situation that the display 275 is in the locked-rotor state, the user can control the rotating assembly 276 to rotate through key operations, voice operations, etc., and automatically adjust the rotation state of the display 275 to restore the locked-rotor state to the standard state.

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

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

S5: In response to the startup of the display device, detect the current rotation state of the display;

S6: If the display is in a locked-rotor state, obtain the startup application type;

S7: Control the rotation of the rotating component according to the startup application type to rotate the display to a standard state.

In this embodiment, when it is determined that the display 275 is in the locked-rotor state, the locked-rotor state of the display 275 can be automatically restored by acquiring the type of the application started by the user. Wherein, the standard state includes the horizontal screen state and the vertical screen state; the startup application type includes the first type of application that only supports the horizontal screen state, such as live TV applications, movie and TV series applications, etc.; the second type that only supports the vertical screen state Types of applications, such as short video applications, comics applications, etc., and the third type of applications that support horizontal and vertical screen states, such as browser applications, etc.

In an implementation manner, as shown in FIG. 16, if the startup application type is a first-type application or a second-type application, the controller 250 is further configured to:

S711: Extract the application support status in the startup application type;

S712: Control the rotation component to rotate the display to the application support state.

If the type of the launched application is the first type of application or the second type of application, the controller 250 may extract the state supported by the launched application, that is, the standard state supported by the launched application. Then, the rotating component 276 is controlled to rotate to rotate the display 275 to a state supported by the launched application.

For example, when the display 275 is in a blocked 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 will determine whether the live TV application supports the application after receiving the application instruction. Screen status. Obviously, the live TV application only supports the horizontal screen state, and the display 275 is rotated to the horizontal screen state, and the live TV screen is presented.

In an implementation manner, if the startup application type is a third-type application, the controller 250 is further configured to:

S721: Obtain a record instruction;

S722: Extract the fourth target state specified in the recording instruction;

S723: Control the rotating component to rotate the display to the fourth target state.

Wherein, the recording instruction is a rotation instruction recorded by the display device when the locked-rotor state was triggered last time. As in the above embodiment, the rotation command is a non-directional command. When the application type is the third type of application, the target state can be determined by recording the command, and the rotation component 276 can be controlled to rotate according to the angle difference. The display 275 rotates to the target state.

For example, if the application launched by the user is a browser application that supports both horizontal and vertical screen states, the controller 250 will first obtain the last rotation instruction, such as rotating from the vertical screen state to the horizontal screen state, and determine the rotation direction as Rotate clockwise, and then rotate the display 275 to the corresponding standard state according to the clockwise rotation direction, and start the browser application at the same time.

S731: Calculate the angle difference between the current locked-rotor state and all standard states, and determine the fifth target state;

S732: Control the rotating component to rotate the display to the fifth target state.

Wherein, the fifth target state is a standard state with the smallest angle difference from the current locked rotor state. Similarly, in this embodiment, the target state can also be determined by calculating the angle difference between the current locked-rotor state and all standard states. And control the rotating component 276 to rotate the display 275 to the target state.

It should be noted that when the display 275 rotates from the locked state to the standard state, a rotating animation can be added as a transition screen during rotation. For example, in the rotation process, if it involves application switching, you can add a rotation animation to block the application switching process; if the launched application is an application that supports both the horizontal screen state and the vertical screen state, because the system framework itself turns to a certain value on the display 275 When the level is reached, the application interface will be rotated, so the rotation animation may not be displayed.

S5: In response to the start of the display device, detect the current rotation state of the display; the rotation state includes a standard state and a locked-rotor state; the locked-rotor state is any of the display switches between the two standard states. An intermediate state

It can be seen from the above technical solutions that the present application provides a display device and a method for restoring a locked-rotor state. The controller 250 of the display device 200 can detect the current rotation state of the display 275 in response to the startup of the display device 200; if the display 275 is in In the locked state, the startup application type is acquired; the rotation component 276 is controlled to rotate according to the startup application type to rotate the display 275 to the standard state. In view of the situation that the display 275 is in a locked state, the controller 250 can determine the standard state supported by the started application by starting the application type, and rotate the display 275 to the standard state supported by the started application, thereby automatically adjusting the rotation of the display 275 State in order to restore from the stalled state to the standard state.
