Note 9
Note 1: Ambient temperature = 25 .

Note 2: To be measured in dark room after backlight warm up 30 minutes.
Note 3: To be measured with a viewing cone of 1 by Topcon luminance meter BM-5A.

Note 4: Definition of response time:
The output signals of photodetector 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 interval between the 10% and 90% of amplitudes. Refer to figure as
below.
