described herein except for that directly attributable to mechanisms and workmanship thereof. No license,
express or implied, is granted under any patent, copyright or other intellectual property right of NEC.
Some electronic parts/components would fail or malfunction at a certain rate. In spite of every effort to
enhance reliability of products by NEC, the possibility of failures and malfunction might not be avoided
entirely. To prevent the risks of damage to death, human bodily injury or other property arising out
thereof or in connection therewith, each customer is required to take sufficient measures in its safety
designs and plans including, but not limited to, redundant system, fire-containment and anti-failure.
The products are classified into three quality grades: "Standard", "Special", and "Specific" of the
highest grade of a quality assurance program at the choice of a customer. Each quality grade is designed
for applications described below. Any customer who intends to use a product for application other than
that of Standard quality grade is required to contact an NEC sales representative in advance.
The Standard quality grade applies to the products developed, designed and manufactured in
accordance with the NEC standard quality assurance program, which are designed for such application as
any failure or malfunction of the products (sets) or parts/components incorporated therein a customer
uses are, directly or indirectly, free of any damage to death, human bodily injury or other property, like
general electronic devices.
Examples: Computers, office automation equipment, communications equipment, test and measurement
equipment, audio and visual equipment, home electronic appliances, machine tools, personal
electronic equipment, industrial robots, etc.
The Special quality grade applies to the products developed, designed and manufactured in accordance
with an NEC quality assurance program stricter than the standard one, which are designed for such
application as any failure or malfunction of the products (sets) or parts/components incorporated therein
a customer uses might directly cause any damage to death, human bodily injury or other property, or
such application under more severe condition than that defined in the Standard quality grade without
such direct damage.
Examples: Control systems for transportation equipment (automobiles, trains, ships, etc.), traffic control
systems, anti-disaster systems, anti-crime systems, medical equipment not specifically
designed for life support, safety equipment, etc.
The Specific quality grade applies to the products developed, designed and manufactured in accordance
with the standards or quality assurance program designated by a customer who requires an extremely
higher level of reliability and quality for such products.
Examples: Military systems, aircraft control equipment, aerospace equipment, nuclear reactor control
systems, medical equipment/devices/systems for life support, etc.
The quality grade of this product is the "Standard" unless otherwise specified in this document.

1. OUTLINE
1.1 STRUCTURE AND PRINCIPLE
Color LCD module NL3224BC35-22 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.
1.2 APPLICATION

be more than minimum "VS". Otherwise the lamp may not be turned on because the lamp
