10. Display dignity
The item concerning externals and the display dignity is decided by the shipment inspection standard book..
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.
Blow away dust on the polarizer with antistatic ï¼®₂ 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 set the human earth
when handling. Observe all other precautionary requirements in handling components.
ç h) Since there is a circuit board in the module back, stress is not added at the time of a design assembly.
If stress is added, there is a possibility that circuit parts may be damaged.
ç 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 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.
If a light strong against a LCD panel is irradiated, it may lead to degradation of the panel characteristic
and display grace may get worse.
l) Connect GND to 4 place of mounting holes to stabilize against EMI and external noise.
m) 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, discoloration, degradation of display grace, and
abnormalities of operation.
n) When install LCD modules in the cabinet, please tighten with “torque = max 0.441 Nŋm (max 4.5kgfŋcm).
Be sure to confirm it in the same condition as it is installed in your instrument.
o) 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.
ç p) Notice : Never dismantle the module , because it will cause failure.
Moreover, please do not peel off and do not cut the tapes pasted to the product.
However, the tape fixed panel protection film is excluded.
ç q) Be careful when using it for long time with fixed pattern display as it may cause afterimage.
(Please use a screen saver etc., in order to avoid an afterimage.)
ç r) 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.
s) 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.
t) The LED used for this product is very sensitive to the temperature. Luminance decreases rapidly when it
isused for a long time under the environment of the high temperature.çPlease consult our company when it is
used under the environment like the above mentioned.
u) Epoxy resin (amine series curing agent), silicone adhesive material (dealcoholization series and oxime
series), tray forming agent (azo compound) etc, in the cabinet or the packing materials may induce abnormal
display with polarizer film deterioration regardless of contact or noncontact to polarizer film.
Be sure to confirm the component of them.
