INTRODUCTION
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 NL10276BC30-18 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 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.

Note2: The lamp voltage cycle between lamps should be kept on a same phase. "VS" and "VBLH"
are the voltage value between low voltage side (Cold) and high voltage side (Hot).
Note3: The asymmetric ratio of working waveform for lamps (Lamp voltage peak ratio, Lamp
current peak ratio and waveform space ratio) should be less than 5 % (See the following
figure.). If the waveform is asymmetric, DC (Direct current) element apply into the lamp. In
this case, a lamp lifetime may be shortened, because a distribution of a lamp enclosure
substance inclines toward one side between low voltage terminal (Cold terminal) and high
voltage terminal (Hot terminal). When designing the inverter, evaluate asymmetric of lamp
working waveform sufficiently.

Note4: The inverter should be designed so that the lamp starting voltage can be maintained for more
than 1 second. Otherwise the lamp may not be turned on.
Note5: In case "FO" is not the recommended value, beat noise may display on the screen, because of
interference between "FO" and "1/th". Recommended value of "FO" is as following.

evaluate the fluctuation of lamp current, voltage and working waveform sufficiently.
