property rights of any third party arising out of or in connection with application of the products
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 th e
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 NL12880BC20-05D 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.

1.2 APPLICATION

The luminance lifetime is the time from initial luminance to half-luminance.

This lifetime is the estimated value, and is not guarantee value.

Continuous operation, IL=50mA/One circuit

70°C (Surface temperature at screen)

Note1: Life time expectancy is mean time to half-luminance.
Note2: Estimated luminance lifetime is not the value for an LCD module but the value for LED

elementary substance.

Note3: By ambient temperature, the lifetime changes particularly. Especially in case the product

works under high temperature environment, the lifetime becomes short.

7. PRECAUTIONS

7.1 MEANING OF CAUTION SIGNS

The following caution signs have very important meaning. Be sure to read "7.2 CAUTIONS" and

"7.3 ATTENTIONS"!

This sign has the meaning that a customer will be injured or the product will sustain

damage if the customer practices wrong operations.

This sign has the meaning that a customer will be injured if the customer practices

wrong operations.

7.2 CAUTIONS

∗ Do not shock and press the LCD panel and the backlight! There is a danger of

breaking, because they are made of glass. (Shock: Equal to or no greater than 539m/s
and equal to or no greater than 11ms, Pressure: Equal to or no greater than 19.6 N
(φ16mm jig))

NL12880BC20-05D

2

7.3 ATTENTIONS

7.3.1 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 When the product is put on the table temporarily, display surface must be placed downward.
③ 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.

④ The torque for product mounting screws must never exceed 0.23N⋅m. Higher torque might result

in distortion of the bezel. And the length of product mounting screws must be ≤ 2.5mm.

⑤ The 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.

⑥ Do not press or rub on the sensitive product surface. When cleaning the product surface, wipe it

with a soft dry cloth.

⑦ Do not push or pull the interface connectors while the product is working.
⑧ When handling the product, use of an original protection sheet on the product surface (polarizer) is

recommended for protection of product surface. Adhesive type protection sheet may change color
or characteristics of the polarizer.

⑨ Usually liquid crystals don't leak through the breakage of glasses because of the surface tension of

thin layer and the construction of LCD panel. But, if you contact with liquid crystal by any chance,
please wash it away with soap and water.

!

DATA SHEET DOD-PP-1174 (2nd edition)

29

7.3.2 Environment

① Do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive

② In order to prevent dew condensation occurred by temperature difference, the product packing box

③ Do not operate in high magnetic field. If not, circuit boards may be broken.
④ This product is not designed as radiation hardened.

7.3.3 Characteristics

The following items are neither defects nor failures.
