OPrecautions

1) Indusuial(Mechanica1) design of the product in which this LCD module will be incorporated must be made
so that the viewing angle characteristics of the LCD may be optimized.

This module’s vieGig angle is illustrated in Fig.1.

Please consider the optimum viewing conditions according to the purpose when installing the module.

2) This module should be installed using mounting holes of metal bezel.

When installing the module, pay attention and handle carefully not to allow any undue stress such as twist or

bend.

3) Since the front polarizer is easily damaged. Please pay attention not to scratch on its face.
It is recommended to use a transparent acrylic resin board or other type of protective panel on the surface
of the LCD module to protect the polarizer, LCD panel, etc..

4) If the surface of the LCD panel is required IO be cleaned, wipe it swiftly with cotton or other soft cloth. If

it is not still clear completely, blow on and wipe it.

5) Water droplets, etc. must be wiped off immediately since they may cause color changes, staining, etc., if

it remained for a long time.

6) Since LCD is made of glass substrate, dropping the module or banging it against hard objects may cause

cracking or fragmentation.

7) Since CMOS LSIs are equipped in this module, following countermeasures most be taken to avoid
electrostatics charge.

1 I operator

Electrostatic shielding clothes shall be had because it is feared that the static electricity is electrified to

human body in case that operator have a insulating garment.

2. Equipment
There is a possibility that the static electricity is charged to equipment which have a function of peeling
or mechanism of friction(EX: Conveyer, soldering iron, working table), so the
countermeasure(electrostaticearth:l X 10’ Q) should be made.

3. Floor
Floor is a important part to leak static electricity which is generated from human body or equipment.

There is a possibility that the static electricity is charged to them without leakage in case of insulating

floor, so the countermeasure(electrostatic earth:1 X 10’ Q) should be made.

4Humidity

Humidity of working room may lower electrostatics generating material’s resistance and have something
to prevent electrifying. So, humidity should be kept over 50 % because humidity less than 50 % may
increase material’s electrostatic earth resistance and it become easy to electrify.

5.Transportationlstorage
The measure should be made for storage materials because there is a possibility that the static electricity,
which electrify to human body or storage materials like container by friction or perling, cause the
dielectric charge.

6. Others
The laminator is attached on the surface of LCD module to prwent from scratches, fouling and dust.
It should be peeled off unhurriedly with using static eliminator.
And also, static eliminator should be installed to prevent LCD module from electrifying at assembling
line.

8) Don’t use any materials which emit gas from epoxy rcsin(amines’ hardener) and silicon adhesive
agent(dealcohol or deoxym) to prevent change polarizer color owing to gas.

9) Since leakage current, which may be caused by routing of CCFT cables, etc., may affect the brightness of

display, the inverter has to be designed taking the leakage current into consideration. Thorough evaluation of
the LCD module/inverter built into its host equipment shall be conducted, therefore, to ensure the specified
brightness.

10) Avoid to expose the module to the direct sun-light, strong ultraviolet light, etc. for a long time.

11) If stored at temperatures under specified storage temperature, the LC may freeze and be deteriorated.
If storage temperature exceed the specified rating. the molecular orientation of the LC may change to that of

a liquid, and they may not revert to their original state. Therefore, the module should be always stored at norm;
room temperature.

12) Disassembling the LCD module can cause permanent damage and should be strictly avoided.

13) Procedure insert mating connector
When the mating connector is inserted it should be parallel to the used connector of LCD module and it

should be inserted horizontally.

when the mating connector is attempted to be fiied to LCD comxctor, it should be inserted properly io order

not to create a gap as shown “A”.

Please insert the coooector as both edge is placed to the connect position of LCD comxctor.

14) This specification describes display quality in case of no gray scale. Since display quality can be affected by
gray scale methods, display quality shall be carefully evaluated for the usability of LCD module in case gmy
scale is displayed on the LCD module.

15) The module should be driven according to the specified ratings to avoid permamnt damage.
DC voltage drive leads to rapid deteriomtion of LC, so ensure that the drive is alternating waveform by

continuous application of the signal M. ~sneciallv the Dower ON/OFF seauence shown on Page 25 should be
kept to avoid latch-w of drive LSIs and aonlication of DC voltaee to LCD onnel.
