Note 1: Ambient temperature = 25°C.
Note 2: To be measured in dark room after backlight warm up 30 minutes.
Note 3: To be measured with a viewing cone of 2°by Topcon luminance meter BM-5A.
Note 4: Definition of response time:
The output signals of BM-7 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 is between the 10% and 90% of amplitudes. Refer to figure as below.
