•STRUCTURE AND PRINCIPLE
Color LCD module NL2432HC22-41B 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, touch panel (T/P) 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 controller, 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.
