9. Precautions of using LCD Modules
Mounting
-Mounting must use holes arranged in four corners or four sides.
-The mounting structure so provide even force on to LCD module. Uneven force (ex. Twisted stress)
should 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.
-It is suggested to attach a transparent protective plate to the surface in order to protect the polarizer.
It should have sufficient strength in order to the resist external force.
-The housing should adopt radiation structure to satisfy the temperature specification.
-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.
-Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder than HB
pencil lead. Never rub with dust clothes with chemical treatment. Do not touch the surface of
polarizer for bare hand or greasy cloth.(Some cosmetics deteriorate the polarizer.)
-When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials
like chamois soaks with petroleum benzine. Normal-hexane is recommended for cleaning the
adhesives used to attach front / rear polarizers. Do not use acetone, toluene and alcohol because
they cause chemical damage to the polarizer.
-Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer
Operating
-The spike noise causes the mis-operation of circuits. It should be within the ±200mV level (Over and
under shoot voltage)
-Response time depends on the temperature.(In lower temperature, it becomes longer.)
-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.
-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.
-When fixed patterns are displayed for a long time, remnant image is likely to occur.
-Module has high frequency circuits. Sufficient suppression to the electromagnetic interference shall
be done by system manufacturers. Grounding and shielding methods may be important to minimized
the interference
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 interface pin
directly.
Strong Light Exposure
Strong light exposure causes degradation of polarizer and color filter.
Storage
When storing modules as spares for a long time, the following precautions are necessary.
-Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep the
temperature between 5°C and 35°C at normal humidity.
-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.
Protection Film
-When the protection film is peeled off, static electricity is generated between the film and polarizer.
This should be peeled off slowly and carefully by people who are electrically grounded and with well
ion-blown equipment or in such a condition, etc.
-The protection film is attached to the polarizer with a small amount of glue. If some stress is applied
to rub the protection film against the polarizer during the time you peel off the film, the glue is apt
tore main on the polarizer. Please carefully peel off the protection film without rubbing it against the
polarizer.
-When the module with protection film attached is stored for a long time, sometimes there remains a
very small amount of glue still on the polarizer after the protection film is peeled off.
-You can remove the glue easily. When the glue remains on the polarizer surface or its vestige is
recognized, please wipe them off with absorbent cotton waste or other soft material like chamois
soaked with normal-hexane.
Transportation
The LCD modules should be no falling and violent shocking during transportation, and also should avoid
excessive press, water, damp and sunshine.
