Color Filter

TFT-LCD can utilize black, white and other colors according to the
purposes. The Color Filter is a core part which realizes colors in TFT-
LCD.
The color of TFT-LCD screen is realized by TFT and the motions of
liquid crystal cells which control the permeability of white-colored
light of the Back Light (B/L), and the mixture of 3 colors (Red, Green &
Blue) permeated through the color filter.
The Color Filter can be produced either by the staining method or the
pigment method according to the materials of the organic filter. It can
be also made by staining, diffusion, electro-deposition or printing
method depending on the way of manufacture. However, it is the
pigment diffusion method that the most commonly used method to
manufacture TFT-LCD color filter.
A Color Filter (C/F) substrate consists of C/F pattern which realizes
the tone of color, Black Matrix which partitions R.G.B cells and blocks
the light and ITO which gives voltage liquid crystal cells
