Interface, Ultra-Wide Viewing Angle
NL128102AC31-02A module 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 unit. 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. PC, signal generator, etc.) are modulated
into best form for active matrix system by a signal processing board, 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.
