The Copyright to this document belongs to NEC LCD Technologies, Ltd. (hereinafter called "NEC").

No part of this document will be used, reproduced or copied without prior written consent of NEC.

NEC does and will not assume any liability for infringement of patents, copyrights or other intellectual

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 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

systems, medical equipment/devices/systems for life support, etc.

The quality grade of this product is the "Standard" unless otherwise specified in this document.

2.6 LUMINANCE CONTROL

Method Adjustment and luminance ratio

• Adjustment

Backlight luminance can be controlled by duty ratio of the external PWM signal.

To enable external PWM control, keep CN1 7pin Open or GNDB, and CN1 8pin connect

to GNDB of the circuit board.

The PWM signal must follow specification noted in the section 2.3 ELECTRICAL

CHARACTERISTICS.

The variable resistor (R) for luminance control should be 10kΩ ±5%, 1/10W. Minimum

point of the resistor is the minimum luminance. Also maximum point of the resistor is the

maximum luminance.

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

operations.

4.2 CAUTIONS

DATA SHEET DOD-PP-1033 (2nd edition) 11

∗ Be sure to wait for a while after turning the power OFF before replacing. LED

driver is still hot soon after shutting down.

∗ Do not apply mechanical shock. It may damage products.

4.3 ATTENTIONS

4.3.1 Handling of the product

① Do not touch or apply stress to exposed electronic parts. Doing so may cause damage or

malfunctionin g of produc ts. O nly hold the edge of the circuit board when unpacking.

② When handling the product, take measures of electrostatic discharge with such as earth band, ionic

shower and so on, because the product may be damaged by electrostatic.

③ Do not plug or unplug the interface connectors while the product is operating.

④ Do not hook or pull cables such as lamp cable, and so on, in order to avoid any damage.

4.3.2 Environment

① 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 t he prod uc t.

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

must be opened after enough time being left under the environment of an unpacking room.

Evaluate the storage time sufficiently because dew condensation is affected by the environmental

temperature and humidity. (Recommended leaving time: 6 hours or more with the original packing

state after a customer receives the package)

③ Do not operate in high magnetic field. If not, circuit boards may be broken.

④ This product is not designed as radiation hardened.

104PW02F

4.3.3 Others

① All GNDB and VDDB terminals should be used without any non -connected lines.

② Do not disassemble a product.

③ Pack the product with the original shipping package, in order to avoid any damages during

transportation, when returning the product to NEC.

④ Insert spacers between the LED Driver board and the chassis to secure spatial distance.
