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 NL10276BC20-04 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. 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.
1.2 APPLICATION

be more than minimum "VS". Otherwise the lamp may not be turned on because the lamp
starting voltage is less than minimum "VS".

6. PRECAUTIONS
6.1 MEANING OF CAUTION SIGNS
The following caution signs have very important meaning. Be sure to read "6.2 CAUTIONS" and
"6.3 ATTENTIONS", after understanding these contents!
This sign has the meaning that customer will be injured by himself or the product will
sustain a damage, if customer has wrong operations.
This sign has the meaning that customer will get an electrical shock, if customer has
wrong operations.
This sign has the meaning that customer will be injured by himself, if customer has
wrong operations.
6.2 CAUTIONS
∗ Do not touch the working backlight. There is a danger of an electric shock.
NL10276BC20-04
∗ Do not touch the working backlight. There is a danger of burn injury.
∗ Do not shock and press the LCD panel and the backlight! There is a danger of
breaking, because they are made of glass. (Shock: To be not greater 539m/s
not greater 11ms, Pressure: To be not greater 19.6 N (φ16mm jig))
6.3 ATTENTIONS
6.3.1 Handling of the product
① Take hold of both ends without touching the circuit board when the product (LCD module) is
picked up from inner packing box to avoid broken down or misadjustment, because of stress to
mounting parts on the circuit board.
② Do not hook nor pull cables such as lamp cable, and so on, in order to avoid any damage.
③ When the product is put on the table temporarily, display surface must be placed downward.
④ When handling the product, take the measures of electrostatic discharge with such as earth band,
ionic shower and so on, because the product may be damaged by electrostatic.
⑤ The torque for product mounting screws must never exceed 0.294N⋅m. Higher torque might result
in distortion of the bezel.
⑥ he product must be installed using mounting holes without undue stress such as bends or twist (See
outline drawings). And do not add undue stress to any portion (such as bezel flat area). Bends or
twist described above and undue stress to any portion may cause display mura.
⑦ Do not press or rub on the sensitive product surface. When cleaning the product surface, use of the
cloth with ethanolic liquid such as screen cleaner for LCD is recommended.

① Do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive
② In order to prevent dew condensation occurring by temperature difference, the product packing
③ Do not operate in high magnetic field. Circuit boards may be broken down by it.
④ This product is not designed as radiation hardened.
6.3.3 Characteristics
The following items are neither defects nor failures.
① Response time, luminance and color may be changed by ambient temperature.
② Display mura, flicker, vertical seam or small spot may be observed depending on display patterns.
③ Optical characteristics (e.g. luminance, display uniformity, etc.) gradually is going to change
④ Do not display the fixed pattern for a long time because it may cause image sticking. Use a screen
⑤ The display color may be changed depending on viewing angle because of the use of condenser
⑥ Optical characteristics may be changed depending on input signal timings.
