1. OUTLINE
1.1 STRUCTURE AND PRINCIPLE
Color LCD module NL12880BC20-05 is composed of the amorphous silicon thin film transistor
liquid crystal display (a-Si TFT LCD) panel structure with driver LSIs for driving the TFT (Thin Film
Transistor) array and a backlight.
The a-Si TFT LCD panel structure is injected liquid crystal material into a narrow gap between the
TFT array glass substrate and a color-filter glass substrate.
Color (Red, Green, Blue) data signals from a host system (e.g. signal generator, etc.) are modulated
into best form for active matrix system by a signal processing circuit, and sent to the driver LSIs which
drive the individual TFT arrays.
The TFT array as an electro-optical switch regulates the amount of transmitted light from the
backlight assembly, when it is controlled by data signals. Color images are created by regulating the
amount of transmitted light through the TFT array of red, green and blue dots.
