11. Display Quality
12.Handling Precautions
b) Be sure to design the cabinet so that the module can be installed without any extra stress such as
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.
g) Since CMOS LSI is used in this module, take care of static electricity and injure the human earth
i) Protection film is attached to the module surface to prevent it from being scratched .
j) The polarizer surface on the panel is treated with Anti-Glare for low reflection. In case of attaching
k) Do not expose the LCD panel to direct sunlight. Lightproof shade etc. should be attached when LCD
n) When handling LCD modules and assembling them into cabinets, please avoid that long-term storage in
o) Cold cathode fluorescent lamp in LCD panel contains a small amount of mercury, please follow local
p) Be careful of a back light lead not to pull by force at the time of the wiring to an inverter, or line processing.
r) Liquid crystal contained in the panel may leak if the LCD is broken. Rinse it as soon as possible if it gets
c) Since the front polarizer is easily damaged, pay attention not to scratch it.
h) Since there is a circuit board in the module back, stress is not added at the time of a design assembly.
l) Connect GND to 4 place of mounting holes to stabilize against EMI and external noise.
m) There are high voltage portions on the backlight and very dangerous. Careless touch may lead to
q) When install LCD modules in the cabinet, please tighten with “torque=0.294 ± 0.02N ･ m(3.0 ± 0.2kgf ･ cm)”.
t) Be careful when using it for long time with fixed pattern display as it may cause afterimage.
u) Adjusting volume have been set optimally before shipment, so do not change any adjusted value.
w) The lamp used for this product is very sensitive to the temperature.
s) Notice : Never dismantle the module , because it will cause failure. Please don't remove the fixed tape,
v) If a minute particle enters in the module and adheres to an optical material, it may cause display

recommended to peel off softly using the adhesive tape when soil or finger oil is stuck to the polarizer. When unavoidable,
wipe off carefully with a cloth for wiping lenses.
when handling.Observe all other precautionary requirements in handling components.
Peel the film off slowly , just before the use, with strict attention to electrostatic charges.
(Please use a screen saver etc., in order to avoid an afterimage.)
If adjusted value is changed, the specification may not be satisfied.

a) Be sure to turn off the power supply when inserting or disconnecting the cable.
Luminance decreases rapidly when it is used for a long time or repeatedly under the environment of the
low temperature or the module is being cooled. Please avoid the continuous or repeating use of it under such an
environment. It may decrease up to 50% of the initial luminance in about one month under the low temperature
environment. Please consult our company when it is used under the environment like the above mentioned.
The display quality of the color TFT-LCD module shall be in compliance with the Incoming Inspection Standard.
