Contrast ratio is calculated with the following formula.
luminance meter BM-7, after 10 minutes operation.
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 is defined as the time interval between the 10% and 90% of
amplitudes. Refer to figure as below.
