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...
