Abstract

The invention relates to a flat-panel television protection screen, which comprises a transparent panel, a shading rim which is arranged on the peripheral edge of the transparent panel and a buffering layer which is adhered onto the shading rim, wherein at least one heat radiation device is arranged on the position corresponding to a flat-panel television frame, and the flat-panel television protection screen is characterized in that the heat radiation device comprises a first main contact surface which is contacted with the outer surface of the flat-panel television frame, a second main contact surface which is contacted with the inner surface of the shading frame and one or more heat radiation passages which extends in the length direction of the first main contact surface and the second main contact surface, wherein the first main contact surface is parallel to the second main contact surface, at least one of the two end surfaces formed by an port of one or more heat radiation passages is provided with a ventilation film. The flat-panel television protection screen is used for protecting a flat-panel television display device, simultaneously the heat radiation problem of the protection screen is also solved, and the influence of small particles such as dust, fogdrop and the like on the flat-panel television display device can be effectively avoided.

Description

technical field [0001] The present invention relates to a protective screen, more specifically, the present invention relates to a protective screen for a flat panel television. Background technique [0002] Liquid crystal display technology has developed very rapidly in recent years, and is mainly used in the application of monitors such as computers and televisions. [0003] Liquid crystal display includes three core components of liquid crystal display screen, backlight source and drive circuit. There are many types of liquid crystal displays, and the widely used ones are mainly displays made of the electro-optic effect of liquid crystals, mainly including thin-film transistor liquid crystal display TFTLCD, twisted nematic liquid crystal display and double twisted nematic liquid crystal display. Thin-film-transistor-type liquid crystal displays have dominated the flat-panel display market due to their advantages of low power consumption and low radiation. The existing l...
