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
system
s, 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 NL10276BC24-19D 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.

5. ESTIMATED LUMINANCE LIFETIME
The luminance lifetime is the time from initial luminance to half-luminance.
This lifetime is the estimated value, and is not guarantee value.
LED elementary substance
Note1: MTTF is mean time to half-luminance.
Note2: Estimated luminance lifetime is not the value for 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", after understanding these contents!
This sign has the meaning that customer will be injured by personnel, if customer has
wrong operations.
www.panelook.com
NL10276BC24-19D
!
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: To be not greater 539m/s
11ms, Pressure: To be not greater 19.6 N (
7.3 ATTENTIONS
7.3.1 Handling of the product
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.
ཱ When the product is put on the table temporarily, display surface must be placed downward.
ི 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.
ཱི 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.
ུ Do not press or rub on the sensitive product surface. When cleaning the product surface, wipe it
with a soft dry cloth.
ཱུ Do not push nor pull the interface connectors while the product is working.
ྲྀ 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.
ཷ 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 for the worst,
please wash it out with soap.
This sign has the meaning that customer will be injured by personnel or the product
will sustain a damage, if customer has wrong operations.

7.3.2 Environment
Do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive
gases. Keep the product in packing box with antistatic pouch in room temperature to avoid dusts
and sunlight, when storing the product.
ཱ In order to prevent dew condensation occurring by temperature difference, the product packing
box should be opened after enough time being left under the environment of an unpacking room.
Evaluate the leaving time sufficiently because a situation of dew condensation occurring is
changed by the environmental temperature and humidity. (Recommended leaving time: 6 hours or
more with packing state)
ི Do not operate in high magnetic field. Circuit boards may be broken down by it.
ཱི This product is not designed as radiation hardened.
7.3.3 Characteristics
The following items are neither defects nor failures.
www.panelook.com
NL10276BC24-19D
Response time, luminance and color may be changed by ambient temperature.
ཱ Display mura, flicker, vertical seam or small spot may be observed depending on display patterns.
ི Do not display the fixed pattern for a long time because it may cause image sticking. Use a screen
saver, if the fixed pattern is displayed on the screen.
ཱི The display color may be changed depending on viewing angle because of the use of condenser
sheet in the backlight.
ུ Optical characteristics may be changed depending on input signal timings.
7.3.4 Other
All GND and VCC terminals should be used without any non-connected lines.
ཱ Do not disassemble a product or adjust variable resistors.
ི Pack the product with original shipping package, in order to avoid any damages during
transportation, when returning the product to NEC for repair and so on.
ཱི The information of China RoHS directive six hazardous substances or elements in this product is
