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.

CONFIDENTIAL – DO NOT COPY Page 2-5

File No. SG-0362

(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.
