1. A display device, comprising:
a display panel;
a motor-driven module, which is configured to be connected to the display panel and drive the display panel to move;
a control module, which is configured to control the motor-driven module;
a first module and a second module disposed opposite to each other in a first direction, wherein the first module and the second module are able to move relatively in a second direction;
a first unit, which is disposed on a side of the first module facing the second module; and
a second unit, which is disposed on a side of the second module facing the first module;
wherein in response to a position relationship between the first unit and the second unit, the control module provides a first control signal for the motor-driven module, and
wherein the first direction intersects the second direction;
wherein the first unit is a first capacitive plate and the second unit is a second capacitive plate; and
wherein a voltage of the first capacitive plate changes in response to a position relationship between the first capacitive plate and the second capacitive plate; and the control module controls a working state of the motor-driven module in response to a change of the voltage of the first capacitive plate.
