APPENDIX 1: DEFINITIONS
A. DEFINITION OF CHROMATICITY COORDINATE
B. DEFINITION OF CONTRAST RATIO
C. DEFINITION OF RESPONSE TIME
The chromaticity coordinate is defined as the coordinate value on the CIE
1931 color chart for R, G, B, W.
The contrast ratio is defined as the following formula:
Contrast Ratio =
The definition of turn-on response time Tr is the time interval between a pixel
reaching 10% of steady state luminance and 90% of steady state luminance.
The definition of turn-off response time Tf is the time interval between a pixel
reaching 90% of steady state luminance and 10% of steady state luminance.
It is shown in Figure 2.
