[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides a liquid crystal display screen with a dustproof protection structure, which has the following beneficial effects:

[0014] Through design, a transparent film that is closed from top to bottom is arranged around the display body from top to bottom. The transparent film can effectively prevent dust from the display body. When the stepper motor is started, the driving shaft can be driven to rotate through the active wheel, the belt and the driven wheel.
