Contrast ratio (CR) =
Reliability of Touch Panel
Note4: Definition of response time:
Note5: Definition of contrast ratio:
Note6: Definition of viewing angle (LCD-5200):
The output signals of photo detector are measured when the input signals are changed from
“black＂to“white＂(falling time) and from“white＂to“black＂(rising time), respectively.
The response time is defined as the time interval between the 10% and 90% of amplitudes.
Refer to figure as below:
