White Uniformity

Definition of White Variation (

W):

Measure the luminance of gray level 255 at 9 points

W = Maximum [L(1), L(2) …… L(9)] / Minimum [L(1), L(2) …… L(9)]

Spec : =< 1.33 (In all ranges)

8.11

Contrast ratio

The contrast ration can be calculated by following expression.

Contrast Ratio (CR) = L255 / L0

L255 : Luminance of gray level 255
L0 : Luminance of gray level 0

Typical value:

1000:1

White color adjustment

There are six factory preset white color 11500K, 9300K, 8200K, 7500K, 6500K, sRGB, 5000K

Apply full gray64 pattern, with brightness in 100 % position and the contrast control at 50 % position.

The 1931 CIE Chromaticity (color triangle) diagram (x , y) coordinate for the screen center should be:
