STRUCTURE AND FUNCTIONS

A TFT color LCD module comprised a TFT LCD panel, LSIs for driving liquid crystal, and a backlight. The
TFT LCD panel is composed of a TFT array glass substrate superimposed on a color filter glass substrate with
liquid crystal filled in the narrow gap between two substrates. The backlight apparatus is located on the backside
of the LCD panel.

RGB (Red, Green, Blue) data signals are sent to LCD panel drivers after modulation into suitable forms for
active matrix addressing through signal processor.

Each of the liquid crystal cells acts as an electro-optical switch that controls the light transmission from the
backlight by a signal applied to a signal electrode through the TFT switch.

Notes1. Apply VDCB within the LCD operation period. When the backlight turns on before LCD operation or the

LCD operation turns off before the backlight turns off, the display may momentarily become white.

2. When the VDC is off, please keep whole logic signals at “0 V.” In case of the signal more than “0.3 V,”
internal circuit may get damaged.

3. Please turn off V

DC when the signals are put off. If the signals are put off without keep VDC, the display

may be un-uniformity.

5. While the power is off, please keep whole signals (HS, VS, EXTCLK) at low level or high impedance.

6. Wrong power sequence may damage to the module.

GENERAL CAUTIONS

Next figures and sentence are very important, Please understand these contents as follows.

This figure is a mark that you will get hurt and/or the module will have damages when

CAUTION

This figure is a mark that you will get an electric shock when you make a mistake to operate.

This figure is a mark that you will get hurt when you make a mistake to operate

CAUTION

Do not touch an inverter, on which is stuck a caution label··· while the LCD module is under the operation,
because of dangerous high voltage.

you make a mistake to operate.

(1) Caution when taking out the module

a) Pick the pouch only, when taking out the module from a slipping box.

(2) Cautions for handling the module

a) As the electrostatic discharges may break the LCD module, handle the LCD module with care against

electrostatic discharges.

b) As the LCD panel and backlight element are made from fragile glass material, impulse and pressure

to the LCD module should be avoided.
c) As the surface of polarizer is very soft and easily scratched, use a soft dry cloth without chemicals for cleaning.
d) Do not pull the interface connectors in or out while the LCD module is operating.
e) Put the module display side down on a flat horizontal plane.
f) Handle connectors and cables with care.
g) When the module is operating, do not lose EXTCLK, HS, or VS signal. If any one of these signals is lost,

the LCD panel would be damaged.

(3) Cautions for the atmosphere

a) Dew drop atmosphere should be avoided.
b) Do not store and/or operate the LCD module in a high temperature and/or high humidity atmosphere. Storage

in an Electro-conductive Polymer Packing Pouch and under relatively low temperature atmosphere is
recommended.

c) This module uses a cold cathod fluorescent lamp. Therefore, the life time of the lamp becomes short

conspicuously at low temperature.

d) Do not operate the LCD module in high magnetic field.

(4) Caution for the module characteristics

a) Do not apply the fixed patterns data signal to the LCD module at product aging. In order to avoid image

sticking, do not display with fixed pattern. Periodic change of display pattern is recommended.

NL3224AC35-01, 13

(5) Other cautions

a) Do not disassemble and/or reassemble LCD module.
b) Do not readjust variable resistors nor switches, etc.
c) When returning the module for repair etc., pack the module not to be broken. We recommend the original

shipping packages.

Liquid Crystal Display has the following specific characteristics. There are not defects or malfunctions.

The display condition of the LCD module may be affected by the ambient temperature.
The module has cold cathode tube for backlighting. Optical characteristics, like luminance or
uniformity, will change during time.

Uneven brightness and/or small spots may be noticed depending on different display patterns.

While NEC Corporation has been making continuous effort to enhance the reliability of its Electronic
Components, the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury
to persons or property arising from a defect in an NEC Electronic Components, customers must incorporate
sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features.
NEC devices are classified into the following three quanlity grades:
"Standard", "Special", and "Specific". The Specific quanlity grade applies only to devices developed based on
a customer designated "quality assurance program" for a specific application. The recommended applications
of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each
device before using it in a particular application.
Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio
and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial
robots.
Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life
support)
Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support
system or medical equipment for life support, etc.
The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books.
If customers intend to use NEC devices for applications other than those speci fied for Standard quality grade,
they should contact an NEC sales representative in advance.
Anti-radioactive design is not implemented in this product.
