STRUCTURE AND FUNCTIONS
A color TFT (thin film transistor) LCD module is prised of a TFT liquid crystal panel structure, LSIs for driving the TFT array, and a backlight assembly. The TFT panel structure is created by sandwiching liquid crystal material in the narrow gap between a TFT array glass substrate and a color filter glass substrate. RGB (red, green, blue) data signals from a source system is modulated into a form suitable for active matrix addressing by the onboard signal processor and sent to the driver LSIs which in turn addresses the individual TFT cells. Acting as an electro-optical switch, each TFT cell regulates light transmission from a backlight assembly when activated by the data source. By regulating the amount of light passing through the array of red, green,...
