9.PRECAUTIONS
Please pay attention to the followings when you use this TFT/LCD module.
9.1 MOUNTING PRECAUTIONS
(1) You must mount a module user holes arranged in four corners.
(2) You should consider the mounting structure so that uneven force (ex. twisted stress) is not applied
to the module.
And the case on which a module is mounted should have sufficient strength so that external
force is not transmitted directly to the module.
(3) Please attach the surface with a transparent protective plate in order to protect the polarizer LC cell.
Transparent protective plate should have sufficient strength in order to resist external force.
(4) You should adopt radiation structure to satisfy the temperature specification.
(5) Acetic acid type and chlorine type materials for the cover case are not desirable because the former
generates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit
break by electro-chemical reaction.
(6) Do not touch, push or rub the exposed polarizer with glass, tweezers or anything harder than HB
pencil head And Please do not rub with dust clothes with chemical treatment.
Do not touch the surface of polarizer for bare hand or greasy cloth. (Some cosmetics are
detrimental to the polarizer.)
(7) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials
like chamois soaked with petroleum benzene. Normal-hexane is recommended for cleaning the
adhesives used to attach front / rear polarizer. Do not use acetone, toluene and alcohol because
they cause chemical damage to the polarizer.
(8) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer causes
deformations and color fading.
(9) Do not open the case because inside circuits do not have sufficient strength.
9.2 OPERATING PRECAUTIONS
(1) The spike noise causes the malfunction of circuits. It should be lower than following voltage :
V =
±
200mV (Over and under shoot voltage).
(2) Response time depends on the temperature. (In lower temperature, it becomes longer.)
(3) Brightness depends on the temperature. (In lower temperature, it becomes lower.)
And in lower temperature, response time (required time that brightness is stable after turned on )
becomes longer.
(4) Be careful for condensation at sudden temperature change. Condensation makes damage to
polarizer or electrical contacted parts. And after fading condensation, smear or spot will occur.
(5) When fixed patterns are displayed for a long time, remnant image is likely to occur.
(6) A module has high frequency circuit. If you need to shield the electromagnetic noise, please do
co-work together.
9.3 ELECTROSTATIC DISCHARGE CONTROL
Since a module is composed of electronic circuits. It is not strong to electrostatic discharge. Make
certain that treatment persons are connected to ground through wrist band etc. And don’t touch I/F pin
directly.
9.4 PRECAUTION FOR STRONG LIGHT EXPOSURE
Strong light exposure causes degradation of polarizer and color filter.
9.5 STORAGE
When storing modules as spares for a long time. The following precautions are necessary.
(1) Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep the
temperature between 5
and 35
at normal humidity.
(2) The polarizer surface should not come in contact with any other object.
It is recommended that they be stored in the container in which they were shipped.
