2.3. White Balance Alignment
Only
HDMI
input requires color temperature adjustment, all other inputs are relative to it. Both
Warm
and
Cool
Color Coordinate are relative to
Normal
Color Temperature mode. See Appendix
p
“
CVBS/RGB/CMP/VGA Relative Matrix Offset and WARM/COOL Relative Matrix Offset
”. Those
offsets values don’t require any alignment but can be fine-tuned in Factory Menu as well.
Note: Every lot the relative offset is different. We need to align 5 sets first to get the relative
offset data every lot.
White balance alignment should be carried out using a contact less analyzer (e.g. Minolta
CA-210). The probe may not touch the screen surface and should be keep perpendicular to the
screen surface at an angle of 90+/-2°. Measurement must be performed in a dark environment.
Three kinds of color temperature: Normal, cool and warm, should be adjusted separately.
Before Alignment white balance need to INIT WB.
