Abstract

The invention provides a dustproof device for a liquid crystal display. The dustproof device comprises the liquid crystal display and a casing. The contact area for the casing and the liquid crystal display is at least provided with one sealing ring. One side, departing from the liquid crystal display, of the casing is equipped with a dustproof structure. The dustproof device for the liquid crystal display prevents dust from entering the liquid crystal display owing to dual-layer dust-proof effects including the sealing ring and the dustproof structure. The dustproof device for the liquid crystal display is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of display screen protection, and more specifically, to a liquid crystal display screen dustproof device. Background technique [0002] A liquid crystal display (LCD) is a type of display used in various instruments, computers, and televisions. LCD displays use two sheets of polarized material with a liquid crystal solution between them. Passing an electric current through the liquid rearranges the crystals so that optical fibers cannot pass through them. The LCD screen has relatively high environmental requirements. If too much dust or garbage enters the screen, it will affect the display effect. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a liquid crystal display screen dustproof device with simple structure and low cost. [0004] In order to achieve the above object, the liquid crystal display screen dustproof device of the prese...
