Display control device for adaptive rotation angle control and vehicle employing device

A vehicle comprising a display screen and a display control device, the display control device comprising:

• a rotation controller configured to receive a first rotation signal, a second rotation signal, and a vehicle status signal;
• a drive circuit, an input end of the drive circuit being electrically connected with the rotation controller, and an output end of the drive circuit being electrically connected with a display screen,
• wherein the rotation controller is configured to control the drive circuit to output a first drive signal to drive the display screen to a landscape state in response to receiving the first rotation signal, and control the drive circuit to output a second drive signal to drive the display screen to a portrait state in response to receiving the second rotation signal, and
• the rotation controller is further configured to control the drive circuit to drive the display screen to a corresponding position according to the vehicle status signal, and the rotation controller is further configured to control the drive circuit to suspend working in response to the vehicle being in a driving state;
• wherein the display control device further comprises an acceleration detection device, the acceleration detection device is electrically connected with the rotation controller, the acceleration detection device is configured to detect a rotational acceleration of the display screen, the rotation controller is further configured to control the drive circuit to reduce a current of the first drive signal or a current of the second drive signal in response to the rotation acceleration being greater than or equal to a preset acceleration, and the rotation controller is further configured to control the drive circuit to increase the current of the first drive signal or the current of the second drive signal in response to the rotation acceleration being less than the preset acceleration.
