1. Contrast ratio(CR) is defined mathematically as :It is measured at center point(1)

Surface luminance with all white pixels

Contrast ratio =

---------------------------------------------------------

Surface luminance with all black pixels

2. Surface luminance is the luminance value at center 1 point(1) across

the LCD surface 50cm from the surface with all pixels displaying white.

For more information see FIG 8.

3. The variation in surface luminance ,

Minimum (P1,P2 …..P9)

Maximum (P1,P2 …..P9)

For more information see Figure 8.
