LCD black film display device

Abstract

The invention discloses an LCD black film display device. The device comprises a positioning plate, positioning holes, a shell, a panel, terminals, a waiting button, an opening button, a closing button, a sterilization button, a completion button, a timer setting button, a use time button, a time reset button, a use frequency button, a lamp time setting button, an elastic silica gel spraying layer, a waterproof film, a dustproof film, a backlight module, a lower polarizing plate, a PCB substrate, a thin film transistor, liquid crystal, a common electrode, a protective film, a black film, a color filter, a heating pipe, an activated carbon net, a through hole and a rubber insulating layer. The shell is welded to the middle of the top of the positioning plate. According to the display device, the contrast is high, the visual angle is sound, use is convenient, the heat radiation effect is good, a certain anti-static effect is achieved, and a certain waterproof and dustproof effect is achieved.

Description

technical field [0001] The invention relates to the technical field of LCDs, in particular to an LCD black film display device. Background technique [0002] The structure of the LCD is to place a liquid crystal cell between two parallel glass substrates, set a TFT (thin film transistor) on the lower substrate glass, and set a color filter on the upper substrate glass, and control the liquid crystal molecules by changing the signal and voltage on the TFT. Rotate the direction, so as to achieve the purpose of controlling whether the polarized light of each pixel is emitted or not, and the background color of the VALCD products produced by the black and white LCD industry in the prior art is not black enough, especially under high and low temperature conditions, resulting in contrast. Not good, poor viewing angle and other problems, it is inconvenient to use, at the same time, the display device has poor heat dissipation effect, does not have a certain anti-static effect, affe...

[0002] The structure of the LCD is to place a liquid crystal cell between two parallel glass substrates, set a TFT (thin film transistor) on the lower substrate glass, and set a color filter on the upper substrate glass, and control the liquid crystal molecules by changing the signal and voltage on the TFT. Rotate the direction, so as to achieve the purpose of controlling whether the polarized light of each pixel is emitted or not, and the background color of the VALCD products produced by the black and white LCD industry in the prior art is not black enough, especially under high and low temperature conditions, resulting in contrast. Not good, poor viewing angle and other problems, it is inconvenient to use, at the same time, the display device has poor heat dissipation effect, does not have a certain anti-static effect, affects the accuracy of the device, and does not have a certain waterproof and dustproof effect. Therefore, a LCD black film is designed display device is necessary
