Pattern-1
Alignment method:
Initial Set-up:
1. Select source as “PC”.
2. Set Contrast = 58 (Sharp) and Brightness=100 (Sharp) , at normal menu mode.
3. Apply “5 white block”(pattern-1) pattern by VGA pattern generator.
4. Enter factory mode menu: press MENU + Numeric keys “1999” (factory mode menu).
Alignment:
At factory mode menu, select AUTO_COLOR item. Then press “OK” key to adjust ADC_GAIN_R, ADC_GAIN_G, ADC_GAIN_B and
ADC_OFFSET_R, ADC_OFFSET_G, ADC_OFFSET_B. Then store those values to NVM.
Set Contrast = 100 (Sharp) and Brightness=100 (Sharp)
Check color temperature specification with PC mode.
Color temperature Normal/Warm/Cool (x, y) co-ordinates specification:

with
Knoica Minolta CS-200
.
Note:
1. Use
Knoica Minolta CS-200
. for color coordinates and luminance check.
2. For suitable mass production at factory, colour analyzers CA-210 can be applied. But, befor measureing ,all CA-210 should be coordinates
and proofread with a Charoma Meter (CS-200) or equivalent instrument and a reference TV set.
3. Check the luminance in the center of the screen with 100% White. And to Brightness control at 100; Contrast control at 100
