4.8 Mis-convergence
The maximum convergence error to be measured on a white spot or white display line to
represents the maximum distance between the energy centers of any two primary colors.
(See Fig. 6)
CONVERGENCE SPEC.
Zones 0.27 mm CRT
Zone C 0.15 mm
Zone A 0.25 mm
Zone B 0.35 mm
4.9 Focus check ( 68.7 KHZ / 85 HZ )
Adjust brightness control to center click and contrast control to get 25 FL at full white
pattern , then generate me characters to cover entire of the picture the characters should
be clearly identified in all display area. (See Fig. 7)
4.10 Luminance uniformity
condition : With full white pattern, set contrast control at maximum position
and brightness control at center click position.
The center of the display is 30 FL+/-5. , the Max. deviation of the screen
should not exceed 25% .
4.11 White color adjustment
Based on the 1931 CIE chromatic
diagram (x,y)
coordinates of white display on screen center should be:
For 9300 K X = 0.283 0.015 (+/- 0.018 for B grade CRT of PH)
Y = 0.297 0.015
For 6500 K X = 0.313 0.015
Y = 0.329 0.015
For sRGB X = 0.313 0.015
Y = 0.329 0.015
Check conditions :
Set brightness control at center click position and contrast at maximum position.
4.12 Color tracking on full white pattern
To adjust the luminance output from 3 to 30 FL. By turning the contrast control
(brightness control at center click position), the color co-ordinates should not deviate
more than the following tolerance when compare to display center:
X= X (center) 0.015
Y= Y (center) 0.015
For VGA mode <45KHz Zone B: 0.4mm.
(+/- 0.018 for B grade CRT of PH)
(+/- 0.018 for B grade CRT of PH)
(+/- 0.018 for B grade CRT of PH)
(+/- 0.018 for B grade CRT of PH)
(+/- 0.018 for B grade CRT of PH)
