12.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.
Blow away dust on the polarizer with antistatic N2 blow. It is undesirable to wipe off because a polarizer is sensitive.
It is 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.
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.Observe all other precautionary requirements in handling components.
h) Since there is a circuit board in the module back, stress is not added at the time of a design assembly.
Please make it like. If stress is added, there is a possibility that circuit parts may be damaged.
i) Protection 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.
Blow off 'dust' on the polarizer by using an ionized nitrogen.
j) The polarizer surface on the panel is treated with Anti-Glare for low reflection. In case of attaching
protective board over the LCD, be careful about the optical interface fringe etc. which degrades display quality.
k) Do not expose the LCD panel to direct sunlight. Lightproof shade etc. should be attached when LCD panel is
used under such environment.
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 electrical shock.
When exchange lamps or service, turn off the power without fail.
n) When handling LCD modules and assembling them into cabinets, please be noted that long-term storage in
the environment of oxidization or deoxidization gas and the use of such materials as reagent,solvent, adhesive,
resin, etc. which generate these gasses, may cause corrosion and discoloration of the LCD modules.
o) Cold cathode fluorescent lamp in LCD panel contains a small amount of mercury, please follow local ordinances
or regulations for disposal.
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.
q) When install LCD modules in the cabinet, please tighten with “torque = 0.294±0.02N・m (3.0±0.2kgf・cm)”.
Be sure to confirm it in the same condition as it is installed in your instrument.
r) Liquid crystal contained in the panel may leak if the LCD is broken. Rinse it as soon as possible if it gets inside your eye
or mouth by mistake.
s) Notice: Never dismantle the module , because it will cause failure.
t) Be careful when using it for long time with fixed pattern display as it may cause afterimage.
u) Adjusting volume has been set optimally before shipment, so do not change any adjusted value.
If adjusted value is changed, the specification may not be satisfied.
v) If a minute particle enters in the module and adheres to an optical material, it may cause display non-uniformity issue,
etc. Therefore, fine-pitch filters have to be installed to cooling and inhalation hole if you intend to install a fan.
w) The lamp used for this product is very sensitive to the temperature.
Luinance 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.
