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.

Note1: When designing of the power supply , take the measures for the prevention of surge voltage.
Note2: The power supply lines (VDDB and GNDB) have large ripple voltage during luminance control of
LCD lamps. There is the possibility that the ripple voltage produces acoustic noise and signal
wave noise in audio circuit and so on. Put a capacitor (5,000 to 6,000
supply lines (VDDB and GNDB) to reduce the noise, if the noise occurred in the circuit.
Note3: Measured value with high voltage probe of a load capacitance of 3pF.
It is guaranteed that the adaptable LCD module can be turned on at Ta= -10 to +75°C.

2.7 LUMINANCE CONTROL
2.7.1 Luminance control methods
Method Adjustment and luminance ratio PWSEL terminal BRTP terminal
• Adjustment
The variable resistor (R) for luminance control should be
10kΩ ±5%, 1/10W. Minimum point of the resistance is the
minimum luminance and maximum point of the re sistance
is the maximum luminance.
The resistor (R) must be connected between BRTH-BRTI
terminals.

Note4
(BRTH is connected to GNDB in the product.)
• Luminance ratio Note3
• Adjustment
Voltage control method works, when BRTH terminal is 0V
and VBI voltage is input between BRTI-BRTH terminals.
This control method can carry out continuation adjustment
of luminance.
Luminance is the maximum when BRTI terminal is Open.
• Luminance ratio Note3
• Adjustment
Pulse width modulation (PWM) method works, when
PWSEL signal is High and PWM signal (BRTP signal) is
input into BRTP terminal. The luminance is controlled by
duty ratio of BRTP signal.
• Luminance ratio Note3
Note1: In case of the resistor control method and the voltage control method, noises may appear on
the display image depending on the input signals timing for LCD panel signal processing
board.
Use PWM method, if interference noises appear on the display image!
Note2: The inverter will stop working, if the Low period of BRTP signal is more than 1s while
BRTC signal is High or Open. Then the backlight will not turn on anymore, even if BRTP
signal is input again. This is not out of order. The inverter will start to work when power is
supplied again.
Note3: These data are the target values.
Note4: See "2.7.2 Detail of BRTP timing".

3. RELIABILITY TEST
This test is in accordance with the Reliability Test of the adaptable LCD module. Refer to Reliability
Test of the adaptable LCD module.
4. PRECAUTIONS
4.1 MEANING OF CAUTION SIGNS
The following caution signs have very important meaning. Be sure to read "4.2 CAUTIONS" and
"4.3 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.
4.2 CAUTIONS
∗ Do not touch the inverter while the inverter is working, because there is a danger
of an electric shock.
∗ Do not remove the inverter protection sheet, because there is a danger of an
electric shock.
∗ Be sure to wait some time after turning power OFF before starting replacement
work, because the inverter is charged at a high voltage after working.
∗ Be sure to wait some time after turning power OFF before starting replacement
work, because the inverter is hot after working.
∗ Do not shock the inverter, because there is a danger of breaking.
4.3 ATTENTIONS
!
4.3.1 Handling of the product
① 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.
② 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.
③ Do not push nor pull the interface connectors while the product is working.
④ Do not hook nor pull cables such as lamp cable, and so on, in order to avoid any damage.
⑤ Properly connect the adaptable plug (backlight side) to 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.

sunlight, when storing the product.
should be opened after enough time being left under the environment of an un packing roo m. 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
