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.

the display may momentarily become white.
However, 12 V for backlight should be started up within 80 ms, otherwise, the protection circuit makes
