Note 5: Definition of brightness uniformity

The luminance uniformity is calculated by using following formula.

Non-Luminance(LU)=1-

Note 6: Definition of response time is as follows:

Response time is measured at the time when the luminance changes from “black” to “white”, or

“white” to “black” on the same screen point, by photo-detector. Ton is the time when the luminance

changes from 10% up to 90%. Also Toff is the time when the luminance changes from 90% down to

10%(See the following diagram.).

When the display data is changed from white to black, response time is measured
