9. Touch panel Design Precautions
1. It should prevent front case touching the touch
panel Active Area (A.A.) to prevent abnormal
touch.
It should left gab (e.g. 0.2~0.3mm) in between.
2. Outer case design should take care about the area outside the A.A.
Those areas contain circuit wires which is having different thickness. Touching those areas could de-
form the ITO film. As a result case the ITO cold be damaged and shorten its lifetime.
It is suggested to protect those areas with gasket (between the front case and the touch panel).
The suggested figures are B≥0.50mm; C≥0.50mm 。
3. The front case side wall should keep space
(e.g. 0.2 ~ 0.3mm) from the touch panel.
4. I In general design,
touch panel V.A. should be bigger than the LCD V.A.
and touch panel A.A. should be bigger than the LCD A.A.
10. Precautions for Use of LCD Modules
Please refer to "LCD-Module-Design-Handling-Precaution.pdf".
