STRUCTURE AND FUNCTIONS
A TFT color LCD module comprises a TFT LCD panel, LSIs for driving liquid crystal, and the backlight. The
TFT LCD panel is composed of a TFT array glass substrate superimposed on a color filter glass substrate with
liquid crystal filled in the narrow gap between two substrates. The backlight apparatus is located on the backside
of the LCD panel.
RGB (Red, Green, Blue) data signals are sent to LCD panel drivers after modulation into suitable forms for
active matrix addressing through signal processor.
Each of the liquid crystal cells acts as an electro-optical switch that controls the light transmission from the
backlight by a signal applied to a signal electrode through the TFT switch.
