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

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.

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.

Note7: In case of Inverter with Ballast condenser, "VS" is the voltage level between Ballast
condenser and Connector (Refer to the below “Example of measurement”). "VS" should be
designed to be more than minimum "VS". Otherwise the lamp may not be turned on because
the lamp starting voltage is less than minimum "VS".

6.3 ATTENTIONS
6.3.1 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.
ཱ Do not hook nor pull cables such as lamp cable, and so on, in order to avoid any damage.
ི 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 torque for product mounting screws must never exceed 0.343 Nm. Higher torque might result
in distortion of the bezel. And the length of product mounting screws must be d 2.8mm.

ཱུ 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.
Recommended installing method: Ideal plane "A" is defined by one mounting hole (datum point)
and other mounting holes. The ideal plane "A" should be the same plane within r0.3 mm.

ྲྀ 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.
ཷ Do not push nor pull the interface connectors while the product is working.
ླྀ Do not bend or unbend the lamp cable at the near part of the lamp holding rubber, to avoid the
damage for high voltage side of the lamp.
ཹ Properly connect the plug (backlight side) to adaptable socket (inverter side) without incomplete
connection. After connecting, be careful not to hook the lamp cables because incomplete
connection may occur by hooking the lamp cables. This incomplete connection may cause
abnormal operation of high voltage circuit.
ེ If the lamp cable is attached on the metal part of the product directly, high frequency leak current to
the metal part may occur, then the brightness may decrease or the lamp may not be turned on.
ཻ When not connecting FG of the LCD module to the customer's equipment ground, inverter noise
may create video noise on the LCD screen.
ོ 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.
6.3.2 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.

6.3.3 Characteristics
The following items are neither defects nor failures.
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.
ི Optical characteristics (e.g. luminance, display uniformity, etc.) gradually is going to change
depending on operating time, and especially low temperature, because the LCD has cold cathode
fluorescent lamps.
ཱི 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.
ྲྀ The interference noise between input signal frequency for this product's signal processing board
and luminance control frequency of the inverter may appear on a display. Set up luminance control
frequency of the inverter so that the interference noise does not appear.
ཷ After the product is stored under condition of low temperature or dark place for a long time, the
cold cathode fluorescent lamp may not be turned on under the same condition because of the
general characteristic of cold cathode fluorescent lamp. In addition, when Luminance control ratio
is low in pulse width modulation method inverter, the lamp may not be turned on. In this case,
power should be supplied again.
