OPrecautions

1) EspeciaJJy the power ON/OFF sequence shown on Page.16 shall be followed to avoid

latch-up of drive LSIs and application of OC voltage to LCD panel.

2) Industrial (Mechanical) design of the

incorporated optimized. Please consider the optimum viewing conditions according to the purpose

when installing the module. (For the optical characteristics refer to the table .)

3) This module is installed using mounting holes at the four corners of module. When

installing the module, pay attention and handle carefully not to allow any undue

stress such as twist or bend.

A transparent acry'iic resin board or other type of protective panel should be

attached to the front of the module to protect the polarizer, LCD cells, etc.

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

5) If the surface of the LCD ceJJs needs to be cleaned, wipe it swiftly with cotton or other soft cloth. If still not completely clear, blow on its and wipe.

6) Water droplets, etc., changes, staining, etc.,

7) Since LCD and TOUCH SCREEN is made of glass plates, dropping the moduJe or banging it against hard objects may cause cracking or fragmentation.

8) Since CMOS LSIs are equipped in this module, fo'llowing countermeasures must be

taken to avoid electrostatics charge.

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

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

10) If stored at temperatures below specified storage temperature, the LC may freeze

and be deteriorated. If storage temperatures 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.

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

avoided.

12) Don't use any materials that emit gas from epoxy resin (amines'herdener) and

silicone adhesive agent (dealcohol or deoxym) to prevent change polarizer color owing to gas.

13)Since leakage current, which may ba 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 hots equipment shall be conducted, therefore, to ensure the specified brightness.

l4)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 gray scale is displayed on

the LCD module.

OHANCLING INSTRUCTION FOR TOUCH PANEL

Following precaution should be taken on use of Touch analog detective type and matrix detective type).

1. PRECAUTION ON DESIGNING TOUCH PANEL (please see Touch Panel plane drawing 1.)

1) ACTIVE AREA Active area is described as inputted area by pen or finger, which assures quality clarified on the specifications related to input action such as

functional property. optical property and durabi I ity.

(1) For detection of coordinates and calibration. it should be always

conducted within active area. If it is conducted outside of the act i ve area. it may cause functional error.

(2) Area which is actually inputted by pen or finger should be designed

within active area. lf it is designed outside of the active area. it may cause functional error.

2) NEUTRAL AREA Neutral area is located in outside of the active area by 0.2-1.011x11

(inside of non active area by 0.2 -~l.Onm~). coordinates can be detected. but its location is in outside of the area which clarified on specifications related to input action such as functional property, opt i ca I property and durab i I i ty.

Neutral area detects coordinates when inputted by pen or finger, but

may generate conductive power.

(2) Since a role of non active area is to hold flatness of the upper

electrode film on its structure. hard pushing by pen or on housing

may cause functional error.
