Note 1: Ambient temperature = 2 5°C.
Note 2: To be measured in dark room after backli ght warm up 30 minutes.
Note 3: To be measured with a viewing cone of 2°by Topcon luminance meter B M-5A.
Note 4: Definition of response time: The output signals of B M-7 are measured when the inp ut
signals are changed from “Black ” to “White” (falling time) and from “Wh ite” to “Black” (rising
time), respectively. The response t ime interval is between the 10% an d 90% of amplitudes.
