4.11 White color adjustment
Based on the 1931 CIE chromaticity (colour triangle)
diagram (x, y coordination).
coordination of white display on screen center should be:
for 9300 degree K X = 0.283 +/- 0.015
Y = 0.297 +/- 0.015
for 6500 degree K X = 0.313 +/- 0.015
Y = 0.329 +/- 0.015
for 5500 degree K X = 0.332 +/- 0.015
Y = 0.347 +/- 0.015
for sRGB degree K X = 0.313 +/- 0.015
Y = 0.329 +/- 0.015
Check conditions :
Set brightness control at 50% position and contrast at maximum.
sRGB luminance (Full white pattern): at 68.67K/85Hz, regardless of
brightness 50% and
contrast controls: 23
±
3FL.
4.12 Color tracking on full white pattern
Ref. to white balance alignment result and set brightness at 50%, adjust
contrast control from 5FL to max. position, the colour coordinate
should not deviate more than following tolerance when
compare to display center:
X= X n/- 0.015
Y= Y n/- 0.015
4.13 Purity
Test patterns : Full White / Red / Green / Blue.
Conditions: As stated in item 4.0, the purity must be
checked under specific destinations of earth
magnetic environments and the monitor to be
well degaussed.
After warming-up time of 30 min., no coloured stains may
occur in above four patterns.
4.14 Moire
Condition: Displaying a
full white pattern
, at any pre-set
mode the display size of the sets to be set
as stated in "Fig. 1".
M oire area should be less than 1/3 area @15FL via moire control.
However the OSD moire data of V-moire should have a default value
(mode dependent) for product outgoing .Increasing the moire control value
will have side effect on resolution (degrade focus),and phenomenon of flicker
and sawtooth.
