The rotating assembly 276 may be fixed to the back of the display 275, the rotating assembly 276 is used for fixing to a wall, and the rotating assembly 276 receives a control command from the controller 250 to rotate the display 275 in a vertical plane, so that the display 275 is in a landscape state or a portrait state.
Wherein 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 means substantially vertical in the present application, and the horizontal direction means substantially horizontal.

In the vertical screen state, the display can display the user interface corresponding to the vertical screen state and has interface layout and interaction mode corresponding to the vertical screen state. 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 in the vertical screen state.
The vertical screen state is more suitable for playing pictures 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 the terminal screen through the display device 200, the vertical screen state can avoid the transition scaling of the screen, the display screen of the display 275 is fully utilized, and better user experience is achieved.

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 is limited by the rotating assembly and the assembly structure thereof in the application process, the display device can not rotate continuously in a certain direction after rotating for a certain angle in the certain direction. Therefore, if the rotating component rotates in one direction every time, the rotating component is damaged after being rotated for many times.
In view of the above technical problem, the present embodiment shows a display device, and the structure of the display device and the functions of each component may refer to the above embodiments. On the basis of the above embodiment, the specific operation process of the controller can be seen in fig. 5. The transfer controller is configured to execute step S101 of receiving a user control instruction input by a user;
s102, in response to receiving a control instruction input by a user, reading the rotatable direction of the display
In this embodiment, the user control command may be a user voice, for example, the user voice is "rotate XX degrees to X", "rotate to the vertical screen mode", and the like. In this embodiment, the user control instruction may also be operation information, specifically, the user may output the operation information to the rotary controller through the remote controller, for example, the operation information "rotate XX degrees to X" corresponding to the sound reduction key of the remote controller, and the user triggers the remote controller to output the operation information by touching the sound reduction key.
For a scenario where the user interacts with the controller through the user voice, the user control command is the user voice, and correspondingly, the controller 250 is configured to recognize the user control command;
the user sends user control instructions to the controller 250 through the remote controller. Specifically, the remote controller is usually configured with a plurality of keys, such as: a sound adjustment key, a turntable key, a signal source key, etc. The corresponding relation between each key and the user control instruction can be preset in the actual application process. When the user touches the corresponding key, the remote controller sends a user control command carrying the key to the controller 250.
In the practical application process, the user control command may include a control direction, such as "rotate left to vertical screen mode", and the user control 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 user control instruction contains the control direction;
(1) in the case where the user control instruction includes a control direction:
in response to the user control instruction including a control direction, the controller 250 is configured to read a rotatable margin in the control direction;
specifically, after receiving the user control command, the controller 250 first identifies whether the user information includes the control direction, and if the user control command includes the control direction, the processing flow of the display device may refer to fig. 6A, where the controller 250 is further configured to: executing step S2a1 to read a first rotation margin, which 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).
Each rotating assembly 276 is constrained by its own structure, and if there is a total angle of rotation in the clockwise direction, and the angle of rotation in the clockwise direction is generally greater than or equal to the total angle of rotation in that direction, then the rotating assembly 276 may be damaged. 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, if the display device is constrained by its placement position to have a total angle of rotation in the clockwise direction, which is generally greater than or equal to the total angle of rotation in the clockwise direction, then rotating assembly 276 may encounter an obstacle while rotating 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 dynamic display 275.
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;
the angle that the control direction has rotated (which may also be referred to as the real-time rotation angle) is the result of the monitoring 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 user control command is "rotate 90 degrees clockwise" and the corresponding "clockwise" is the control direction. Controller 250, upon receiving the user control instruction, calls "360 degrees" for the 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'.

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 user control command may not include the control angle, and the preset angle is 90 degrees.
In a possible embodiment, the user control 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 this embodiment, the second rotation allowance is a rotatable angle of the rotating component 276 in a 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 preset direction has rotated by an angle (also referred to as a real-time rotation angle), which is a 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".

in a feasible embodiment, the user control command is "rotate 90 degrees", and "clockwise" in this embodiment is the preset direction. The controller 250 calculates the second rotation margin as "0 degree" and the preset angle as 90 degrees.

s106, the rotating component 276 is further configured to, based on the control of the rotation instruction, bring the display 275 to rotate according to the instruction of the current rotation information.
For example, the following steps are carried out: in a possible embodiment, in the initial state, the real-time rotation angle of the display 275 corresponding to the landscape state is "0 °; the preset angle difference is "5 degrees", the user control command is "rotate clockwise by 90 degrees", and the controller 250 determines "clockwise" as the rotatable direction.

Further, when the display 275 is rotated by 90 degrees in a certain direction, an obstacle (e.g., furniture of a user) may be touched halfway, and the preset angle cannot be completed. When such a problem occurs once or N times, it can be automatically recorded in software and the total angle that the direction can be rotated is modified, for example: when the screen is horizontally arranged, the screen cannot rotate clockwise, and the clockwise direction can rotate by a total angle of 0. Thus, in the above step 4, it is directly returned that there is no margin for rotation in the direction to be rotated.
Alternatively, the rotation direction is fixed to the opposite direction of the previous rotation, for example, clockwise rotation is performed when the screen is turned to the vertical screen, and counterclockwise rotation is performed in the opposite direction when the screen is turned to the horizontal screen.
