Precautions

1) Industrial (Mechanical) 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 viewing angle is illustrated in Fig.1.

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

This module should be installed using mounting holes at the two corners of modules.

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

bend.

Since the front polarizer is easily damaged. Please pay attention not to scratch on its face.

3) 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..

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

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

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

5) remained for a long time.

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 must be taken to avoid electrostatics charge.

l-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.Equipmeot 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(electrostatic earth:1 X lo8 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.

4.Humidity

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.

S.Transportation/storage

The measure should be made for storage materials because there is a possibility that the static electriicity,

which electrify to human body or storage materials like container by friction or peeling, cause the dielectric

charge.

6.0thers The laminator is attached on the surface of LCD module to prevent 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 resin(amines’ agent(dealcohol or deoxym) to prevent change polorizer color owing to gas.

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

10) 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 norma

hardener) and silicon adhesive

room temperature.

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

12) Do not use touch TCP/LCD connection area to prevent interconnection breakdown.

13) Do not apply organic solvent to TWLCD connection area where organic materials are used.

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

scale is displayed on the LCD module.

15) The module should be driven according to the specified ratings to avoid permanent damage. DC voltage drive leads to rapid deterioration of LC, so ensure that the drive is alternating waveform by continuous application of the signal M. Esneciallv the Dower ON/OFF seauence shown on Pave 22 should be kent to avoid latch-un of drive LSI and application of DC voltape to LCD Dane1
