The device listed in these technical literature sheets was designed and manufactured for
use in OA equipment.
In case of using the device for applications such as control and safety equipment for
transportation (aircraft, trains, automobiles, etc. ), rescue and security equipment and
various safety related equipment which require higher reliability and safety, take into
consideration that appropriate measures such as fail-safe functions and redundant system
design should be taken.
Do not use the device for equipment that requires an extreme level of reliability, such as
aerospace applications, telecommunication equipment (trunk lines), nuclear power control
equipment and medical or other equipment for life support.

6-2. Backlight driving
The backlight system is an edge-lighting type with single CCFT (Cold Cathode
Fluorescent Tube).

【Note2】 Calculated Value for reference ( IL × V L)
【 Note3 】 Lamp frequency may produce interference with horizontal synchronous
frequency, and this may cause beat on the display. Therefore lamp frequency shall be
detached as much as possible from the horizontal synchronous frequency and from the
harmonics of horizontal synchronous to avoid interference.
【Note4】 It is defined at 22pF for the ballast capacitor of a DC/AC inverter.
The voltage above this value should be applied to the lamp for more than 1
second to start-up. Otherwise the lamp may not be turned on.
【Note5】 Lamp life time is defined as the time when either ① or ② occurs in the
continuous operation under the condition of Ta = 25℃ and IL = 6.0 mArms.
① Brightness becomes 50 % of the original value under standard condition.
② Kick-off voltage at Ta = 0℃ exceeds maximum value, 1500V rms.
Note) The performance of the backlight, for example life time or brightness, is much
influenced by the characteristics of the DC-AC inverter for the lamp. When you design or
order the inverter, please make sure that a poor lighting caused by the mismatch of the

10. Display Quality
The display quality of the color TFT-LCD module shall be in compliance with the Incoming
Inspection Standard.
11.Handling Precautions
a) Be sure to turn off the power supply when inserting or disconnecting the cable.
b) Be sure to design the cabinet so that the module can be installed without any extra
stress such as warp or twist.
c) Since the front polarizer is easily damaged, pay attention not to scratch it.
d) Wipe off water drop immediately. Long contact with water may cause discoloration or
spots.
e) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
f) Since the panel is made of glass, it may break or crack if dropped or bumped on hard
surface. Handle with care.
g) Since CMOS LSI is used in this module, take care of static electricity and injure the
human earth when handling.
h) Observe all other precautionary requirements in handling components.
i) This module has its circuitry PCBs on the rear side and should be handled carefully in
order not to be stressed.
www.DataSheet4U.comj) Laminated film is attached to the module surface to prevent it from being scratched .
Peel the film off slowly just before the use with strict attention to electrostatic
charges. Ionized air shall be blown over during the action. Blow off the 'dust' on the
polarizer by using an ionized nitrogen gun, etc..
K) Black PET sheet covers some electric components and handle with special care to
avoid mechanical stress and shock on this PET surface.
L) Mounting screw hole can stand torque 1.3~1.5 Kgf-cm.
