9. Precautions
Please pay attention to the followings when you use this TFT LCDmodule.
9-1. Mounting Precautions
(1) You must mount a module using holes arranged in four cornersor four sides.
(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 transparent protective plate to the surface in order to
protect the polarizer. Transparent protective plate should have sufficient
strength in order to the 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 polarizers with glass,tweezers or
anything harder than HB pencil lead. 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 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.

File No. SG-0240
(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 mis-operation 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, smearor spot will occur.
(5) When fixed patterns are displayed for a long time, remnant image is likely to
occur.
(6) 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.
(7) Please do not give any mechanical and/or acoustical impact to LCM. Otherwise,
LCM can’t be operated its full characteristics perfectly.
(8) A screw which is fastened up the steels should be a machine screw. (if not, it
causes metallic foreign material and deal LCM afatal blow)
(9) Please do not set LCD on its edge.
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 interface pin directly.
9-4. Precautions for Strong Light Exposure
Strong light exposure causes degradation of polarizer and color filter.

File No. SG-0240
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°C and 35°C 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.
9-6. Handling Precautions for Protection Film
(1) The protection film is attached to the bezel with a small masking tape. 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.
(2) 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 bezel after the
protection film is peeled off.
(3) You can remove the glue easily. When the glue remains on thebezel surface or
its vestige is recognized, please wipe them off with absorbent cotton waste or
other soft material like chamois soaked with normal- hexane.
