•
Peak brightness - >300 nits at native mode (min.), brightness & contrast
controls are at 100%
•
Luminance uniformity - < 30% (5 points measured).
•
Chromatic uniformity - Deviation ∆ x, ∆ y < 0.030(5 points measured)
•
Color tracking - ∆ x, ∆ y < 0.030 for all grey levels (5 points measured).
z
Luminance variation - The variation in surface luminance , δ WHITE and δ BLACK
are
defined as :
δ WHITE(5P) = Maximum(L

, L
on5
) / Minimum(L
on1
,L

Where L
on1
to L
on5
are the luminance with all pixels displaying white at 5 locations .
z Display video color - Picture at full white, pattern, brightness at 70 %, and
contrast at 50%. The color, temperature at the screen
center should be:
