EXCEPT AS EXPRESSLY SET FORTH HEREIN, NLT DISCLAIMS ANY WARRANTIES, EXPRESS OR
IMPLIED, INCLUDING BUT NOT LIMITED TO MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE, AND DISCLAIMS ANY REMEDIES.
x MAINTENANCE
The specifications of maintenance parts are subject to change with equivalent or better quality. NLT
will not accept maintenance for only mounting parts on circuit board (e.g. connector, fuse, capacitor,
resistor, etc.) or only parts for backlight (e.g. reflector sheet, light guide plate, etc.). but for a whole
module by unit.
If NLT plans to discontinue this product, NLT shall inform it to customers in six (6)-month advance
from the issued date of official announcement. In addition, after the product discontinuation, NLT may

1. OUTLINE
1.1 STRUCTURE AND PRINCIPLE
Monochrome LCD module NL204153AM21-24A 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 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.
1.2 APPLICATION
