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

1. OUTLINE
1.1 STRUCTURE AND PRINCIPLE
Color LCD module NL2432HC22-41K 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, touch panel (T/P) 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 controller, 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
• PDAs
1.3 FEATURES
• Adoption of SR-NLT (Super-Reflective Natural Light TFT) (Transflective type)
• Backlight and touch panel attached
• High luminance
• High contrast
• Including LCD controller and power supply
• 6-bit digital RGB signals
• Compliance with the European RoHS directive (2002/95/EC)

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.
NL2432HC22-41K
∗ 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 3,920m/s
2.5ms)
6.3 ATTENTIONS
6.3.1 Handling of the product
① Take hold of both ends without touching the FPC when the product (LCD module) is picked up from
the tray .
② Do not hook nor pull the FPC 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 product must be installed and/or handled without any stress such as bends or twist. Bends, twist
or any stress to any portion may cause display failures. And also do not put heavy or hard materials
on the product.
⑥ Do not hit or rub the surface of touch panel with hard materials, because it is easily scratched.
(Touch panel pencil-hardness: 3H)
⑦ When cleaning the T/P surface, wipe it with a soft dry cloth.
⑧ Do not push nor pull the FPC while the product is working.
⑨ Do not fold the FPC. When the FPC is folded, pattern disconnection may be caused. In case of
bending FPC, the minimum curvature (R) must be more than 1.0 mm.
⑩ When installing the product, do not contact a conductor such as a metal to the FPC excluding the
terminal area. There is a risk of short circuit which is caused by breakage of insulation layer of the
FPC.
⑪ When installing the product, apply the waterproof design to avoid going of water into the product.
