Note 3:

The luminance uniformity of 5 points is defined by dividing the maximum luminance value by the minimum luminance value

at full white condition.

Note 4: Definition of contrast ratio (CR):

Note 5: Definition of response time:

The output

signals of photo detector are measured when the input signals are changed from “White” to “Black” (falling time)

and from “Black” to “White” (rising time), respectively. The response time interval definition is between 10% and 90% of

amplitude. Please refer to the figure as below.
