Note 1 : Ambient temperature =25 , and lamp current I_L = 6 mArms. To be measured in the dark
room.
Note 2 :To be measured on the center area of panel with a viewing cone of 1 by Topcon
luminance meter BM-5, after 10 minutes operation.
Note 3. Definition of response time:
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.
