Dustproof liquid crystal display

Abstract

The invention discloses a liquid crystal display convenient for dust prevention. The liquid crystal display comprises a base, a reel, dustproof cloth and a spring; a supporting column is fixed to thetop of the base; a displayer is fixed to the side, away from the base, of the supporting column; hooks are fixed to the vertical faces of the two sides, close to the bottom, of the displayer; a dustproof frame is installed on the vertical face of the side, away from the hooks, of the displayer; installing frames are fixed to the two sides of the top of the dustproof frame, and the installing frames are fixedly connected with the displayer through fixing rods. The dustproof liquid crystal display is provided with dustproof cloth and hooks; a hanging rod is pulled to drive the dustproof cloth tomove out of a dustproof cloth groove; the inner side of the dustproof cloth is fixedly connected with the reel, so the dustproof cloth drives the reel to rotate when moving, and the reel drives the clockwork spring to roll; after the hanging rod enters the hook, a clockwork spring recovers deformation to generate elastic force, so the reel tightens the dustproof cloth, the hanging rod is fixed inthe hook, the dustproof cloth covers the display, and dust prevention of the display is facilitated.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a dust-proof liquid crystal display. Background technique [0002] Liquid crystal display is a type of display used in digital clocks and watches and many portable computers. The liquid crystal display is a flat and thin display device consisting of a certain number of color or black and white pixels placed in front of a light source or reflective surface. Liquid crystal display The low power consumption of the screen makes it favored by engineers and is suitable for electronic devices that use batteries. [0003] Although there are many kinds and quantities of current liquid crystal displays, certain problems still exist in the existing liquid crystal displays, which bring certain inconvenience to the use of liquid crystal displays. [0004] When the existing liquid crystal display is in use, a large amount of dust often adheres to the screen of the display, whi...
