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 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.
(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.
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.
