Therefore, if the rotating assembly rotates in one direction each time, the rotating assembly will be damaged after multiple rotations.

Based on the foregoing technical problems, the embodiments of the present application show a display device, and the structure of the display device and the functions of various components can refer to the foregoing embodiments. On the basis of the foregoing embodiment, the specific operation process of the controller can be referred to FIG. 5.

In the actual application process, the preset angle difference can be set according to requirements, and the applicant does not limit the preset angle difference.

In a feasible embodiment, in the initial state, the corresponding real-time rotation angle of the display 275 in the landscape state is "0 degrees"; the preset angle difference is "5 degrees", and the user control command is "rotate 90 degrees clockwise" ", the controller 250 determines that "clockwise" is a rotatable direction.

The angle increase value collected at 5.2S is "2 degrees", and the corresponding real-time rotation angle is "52 degrees";

The current rotation information includes: the current rotation direction and the current rotation angle, and the current rotation direction is the rotatable direction The reverse of, the current rotation angle is the sum of the real-time rotation angle and the preset angle;

Output the rotation command carrying the current rotation information;

The rotation component is further configured to drive the display to rotate according to the instruction of the current rotation information based on the control of the rotation instruction.
The display device according to claim 6 or 7, wherein in response to the difference being greater than a preset angle difference, the total angle that can be rotated in the direction is modified.
A display device, characterized in that it comprises:

monitor;

A rotating component, the rotating component is connected to the display and configured to drive the display to rotate by a preset angle; the display has a rotating state including a horizontal screen state or a vertical screen state;

The controller is configured as:

When the display is in the horizontal screen state, in response to a control instruction input by the user for instructing the display to rotate, controlling the rotation component to rotate the display to the vertical screen state according to the first rotation direction;

In response to a control instruction input by the user again for instructing the display to rotate, control the rotating assembly to rotate the display to a landscape state according to a second rotation direction; wherein, the first rotation direction and the second rotation direction on the contrary.
A display device, characterized in that it comprises:

monitor;

A rotating component, the rotating component is connected to the display and configured to drive the display to rotate by a preset angle; the display has a rotating state including a horizontal screen state or a vertical screen state;

The controller is configured as:

When the display is in the vertical screen state, in response to a control instruction input by the user for instructing the display to rotate, controlling the rotation component to rotate the display to the horizontal screen state according to the first rotation direction;

In response to the user's re-input control instruction for instructing the display to rotate, control the rotating component to rotate the display to the portrait state according to the second rotation direction; wherein, the first rotation direction and the second rotation direction on the contrary.
