6. Reliability Test
6.1 Exposure to high temperature
Touch panel is put into a test machine at the condition of 80 for 120 hours. Then it is left at the room temperature
for 24 hours or more. The measurement must satisfy the following:
- Circuit close resistance: as Sec. 3.3
- Circuit open resistance: as Sec. 3.4
- Contact bounce: as Sec. 3.5
- Linearity test: as Sec. 3.6
6.2
Exposure to low temperature
Touch panel is put into a test machine at the condition of -20 for 120 hours. Then it is left at the room tempera-
ture for 24 hours or more. The measurement must satisfy the following:
- Circuit close resistance: as Sec. 3.3
- Circuit open resistance: as Sec. 3.4
- Contact bounce: as Sec. 3.5
- Linearity test: as Sec. 3.6
Exposure to constant temperature and humidity
Touch panel is put into a test machine at the condition of 60 , 90%RH for 120 hours. Then it is left at the room
temperature for 24 hours or more. The measurement must satisfy the following:
- Circuit close resistance: as Sec. 3.3
- Circuit open resistance: as Sec. 3.4
- Contact bounce: as Sec. 3.5
- Linearity test: as Sec. 3.6
Thermal Shock
Touch panel is put into a test machine at the condition of -20 for 30 minutes, and then 80 for 30 minutes. The
process is repeated by 10 cycles. Then it is left at the room temperature for 24 hours or more. The measurement
must satisfy the following:
- Circuit close resistance: as Sec. 3.3
- Circuit open resistance: as Sec. 3.4
- Contact bounce: as Sec. 3.5
- Linearity test: as Sec. 3.6

8.3
Optical inspection method and optical defect standards refer to document. A001-1; Touch Screen Optical Quality
Standard.
Outside to Viewing Area : any optical defected in this area need to be ignored if no effected to touch screen func-
tion.
Silver Bus Pattern defect : Voids in traces to be less than 50% of the trace width.
8.3.1 Silver Bus Pattern gap: >0.1mm
8.3.2 Silver Bus and Active area gap: No silver ink may project beyond the viewing area.
8.3.3 Printed silver tails must not be bent to less than 4mm radius. Maximum
number of bend repetitions is 10.
Glass defects such as edge chips and scratches refer to A001-1 Touch Screen Optical Quality Standard.
Others
8.5.1 Folding line should be avoided on the pressure sensitive adhesive.
8.5.2 Refer to document A001-1, Touch Screen Optical Quality Standard.
8.5.3 Always store the touch screen in its original shipping container under normal conditions
(20~25°C, 65% RH)
