Alignment:
1. Apply Flat80 pattern (80% white pattern).
2. Set color temperature to "NORMAL".
3. At factory mode menu, adjust the Scaler R Gain, Scaler G Gain, Scaler B Gain values to meet "NORMAL" color coordinates specification
below. Then store those values to NVM
4. Set color temperature to "COOL".
5. At factory mode menu, adjust the Scaler R Gain, Scaler G Gain, Scaler B Gain values to meet "COOL" color coordinates specification below.
Then store those values to NVM
6. Set color temperature to "WARM".
7. At factory mode menu, adjust the Scaler R Gain, Scaler G Gain, Scaler B Gain values to meet "WARM" color coordinates specification
below. Then store those values to NVM
Color temperature Normal/Warm/Cool (x, y) co-ordinates specification:
`
Note:
1. Use Knoica Minolta CS-200
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 at the center of the screen with 100% White. And to set Brightness control at 100; Contrast control at 100.
Luminance > 200cd/m
> 200 cd/m
> 400 cd/m
> 450 cd/m
> TBD cd/m
> TBD cd/m
4. The defult values of Scaler R Gain, Scaler G Gain, Scaler B Gain are all 128. When panel WD is made adjustment, the three values
could not be over 128. That is preventing color saturation after adjusting Contrast and Brithness setting at main menu.
PC mode display adjustment
1. Display quality adjustment
Use timing mode as describe in 2.2, and use the POPO (pixel on pixel off) pattern to adjust the clock until no stripe and adjust the phase until clear
picture.("Auto" will be done every time switching to PC mode and mode change) Check all preset 7 modes.
2. Auto color for signal slicering (B)
