FACTORY & ELECTRONIC ADJUSTMENT
2. Color Temperature Adjustment
2.1.1 Color Temperature setting in DVI Mode:
(1) Turn on PDP set and warm up for over 30 minutes.
(2) Turn on Color Analyzer CA-100 and reset CA-100.
(3) Switch PDP input to DVI mode, press the "Recall" key on remote control to have
PDP set in factory default status.
(4) Set up Video Pattern Generator (Chroma, Model= C2226). Timing set = 640 x
480 @ 60Hz; Video = Panel Link, this is the DVI output mode. Connecting PDP
DVI input to Chroma to receive DVI signal.
(5) Dark level and bright level center block definition:
A. Dark level center block definition:
Pattern set = Pattern name = 1-mosaic,
Color form = norm,
Background color = 0
Foreground color = 17
According to C-2226 user manual, appendix analog-color: Normal Pen from
Pen 17 = R: 102, G: 102, B: 102
102 (output amplifier)/1024 (total amplifier)=10%, therefore the 10% is the
10 IRE white output pattern.
B. Bright level center block definition:
Pattern set = Pattern name = 1-mosaic,
Color form = norm,
Background color = 0
Foreground color = 25
According to C-2226 user manual, appendix analog-color: Normal Pen from
Pen 25 = R: 614, G: 614, B: 614
614 (output amplifier)/1024 (total amplifier)=60%, therefore the 60% is the
60 IRE white output pattern.
(6) There are 3 different modes (DVI, RGB and AV) need color temperature setting;
there are 4 different color temperatures (5400K, 6500D, 9300K and 13800K) in
each mode. Each color temperature needs adjust dark level, bright level, and R,
G, B. The OSD is as below:
