4.9.2 Definition of contrast ratio
4.9.3 Definition of luminance uniformity
4.9.4 Definition of response times
4.9.5 Definition of viewing angles
The contrast ratio is calculated by using the following formula.
The luminance uniformity is calculated by using following formula.
the same screen point, by photo-detector. Ton is the time it takes the luminance change from 90%
down to 10%. Also Toff is the time it takes the luminance change from 10% up to 90% (See the
following diagram.).
Response time is measured, the luminance changes from "white" to "black", or "black" to "white" on
The luminance is measured at near the 5 points shown below.
