As shown in fig. 1, the driving member 4 includes a speed reducer 41 and a motor 42, the speed reducer 41 is located between the component to be driven and the motor 42, and a rotating shaft of the speed reducer 41 extends horizontally forward and is connected with the component to be driven, so as to connect the component to be driven and the motor 42; the speed reducer 41 and the motor 42 are synchronously started to drive the component to be driven to rotate, so that the display 1 is driven to rotate.

In a preferred embodiment, the speed reducer 41 shown in fig. 14 is a first-stage planetary gear speed reducer, the reduction ratio of the first-stage planetary gear speed reducer is 10, the input shaft 411 of the first-stage planetary gear speed reducer is connected to the motor 42, and the output shaft 412 of the first-stage planetary gear speed reducer is connected to the component to be driven.

In another preferred embodiment, as shown in fig. 15, the reducer 41 is a two-stage planetary reducer, the two-stage planetary reducer includes two serially connected one-stage planetary reducers, the input shaft 413 of the two-stage planetary reducer is an input shaft of the one-stage planetary reducer close to the motor, the output shaft 414 of the two-stage planetary reducer is an output shaft of the one-stage planetary reducer far from the motor 42, the input shaft 413 of the two-stage planetary reducer is connected to the motor 42, and the output shaft 414 of the two-stage planetary reducer is connected to the member to be driven; the reduction ratio of the secondary planetary gear reducer is 25.

Preferably, when the display content is displayed on the full screen of the mobile phone, the horizontal and vertical states of the screen of the mobile phone are the horizontal and vertical states of the screen when the external mobile terminal plays the display content. When the mobile phone vertical screen displays the display content, the horizontal and vertical states of the screen are vertical; and when the mobile phone transverse screen displays the display content, the transverse and vertical states of the screen are transverse.

The display state of the display 1 comprises two judgment conditions, the display state of the display 1 comprises a horizontal state (a horizontal screen) and a vertical state (a vertical screen), and when the display state and the horizontal and vertical states of the screen are both horizontal or vertical, the display state is judged to be consistent with the horizontal and vertical states of the screen; when the display state is horizontal and the horizontal and vertical states of the screen are vertical, judging that the display state is inconsistent with the horizontal and vertical states of the screen; and when the display state is vertical and the horizontal and vertical states of the screen are horizontal, judging that the display state is inconsistent with the horizontal and vertical states of the screen.

Specifically, when the display state is inconsistent with the horizontal and vertical states of the screen, the controller 3 controls the driving element 4 to start, and the display 1 is driven to rotate by the driving element 4, so that the purpose of synchronizing the display state with the horizontal and vertical states of the screen is achieved. In a preferred embodiment, initially, the display state of the display 1 is horizontal (that is, the display 1 is a horizontal screen), when a certain video is played on a screen of a mobile phone vertically, the video is displayed on a full screen, and when a user projects the video onto the display 1, the driving member 4 is started, and the display 1 is driven by the driving member 4 to rotate along a vertical plane to a vertical display state, so that the display state of the display 1 is consistent with the horizontal and vertical states of the screen of the mobile phone, and the display 1 plays the video in a vertical display state.
