3. The luminance is measured at near the five points shown below.
4. Definitions of viewing angle are as follows.
5. Definition of response time is as follows.
Luminance uniformity is calculated using the following formula.
Photo-detector output signal is measured when the luminance changes “white” to “black”.
Response times are Ton and Toff of the photo-detector output amplitude. Ton is the time between 100
% and 10 %. Toff is the time between 0 % and 90 %.
