1. OUTLINE

1.1 STRUCTURE AND PRINCIPLE

Monochrome LCD module NL204153BM21-01 and NL204153BM21-01A are 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 monochrome-filter glass substrate.
Grayscale data signals from a host system (e.g. 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. Monochrome images are created by regulating the
amount of transmitted light through the TFT array.
