STRUCTURE AND FUNCTIONS

A color TFT (thin film transistor) LCD module is comprised 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. After the driver LSIs are

connected to the panel, the backlight assembly is attached to the backside of the panel.

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 the backlight assembly when

activated by the data source. By regulating the amount of light passing through the array of red, green, and blue dots,

color images are created with clarity.
