(4) Luminance Uniformity:
The Luminance should be measured at 9 positions on white raster (gray scale level L63).
Uniformity can be calculated by the following expression.
Luminance Uniformity =
(5) Chromaticity:
The values(x,y) of chromaticity coordinates should be measured for the White, Red, Green and Blue Raster(gray
scale level L63) each with a photometer.
(6) Response Time:
The response time (t
the pixels.
Input Signal:
Light intensity
t
: Turn on time is the time for the light intensity of the pixels to go from 90% of its maximum to 10% of its
ON
maximum.
t
: Turn off time is the time for the light intensity of the pixels to go from 10% of its maximum to 90% of its
OFF
maximum.
