Contrast ratio
Brightness
The output signals of photodetector are measured when the input signals are
The response time is defined as the time interval between the 10% and 90% of
amplitudes. Refer to figure as below.
Contrast ratio (CR)=
changed from "black" to "white"(falling time) and from "white" to "black"(rising
time),respectively.
Contrast ratio is calculated with the following formula.
luminance meter BM-7, after 10 minutes operation.
