2-2. White Balance Adjustment (PDM-6100)
2-2-1. Measurement equipment
1.
Color analyzer (CA-100 manufactured by MINOLTA)
2.
Signal generator (ASTRO DESIGN VG-828D)
2-2-2. Measuring procedure
1.
Dab the W/B adjustment jig (CA-100) at the glass face of the
panel.
2.
Connect the Signal generator (VG-828D) to the DVI
terminal.
3.
Input All-white signal and set the picture mode to
DYNAMIC.
4.
Select"PNLCTRL" in the service mode menu and set "0
WBNO" at "0"
5.
Select "SCNR" "SCNB" of "PDPWB" in the service mode
menu, and then adjust following W/B standardized values
of 6500K, 8000K, 9300K, 10000K and 13550K to following
values of X/Y.
W/B standardized values:
W/B
X
Y
6.
After adjusting the values, at the values of the "SCNR" or
"SCNB" exceeding 128 (initialize value).
1) Reset a lager value of the "SCNR" or "SCNB" at 128.
2) Set the White Balances with the last of items and "SCNG"
to the X/Y values above.
7.
After the above step, when these item are nonqualified
following conditions, set the largest one at 128 and readjust
the White Balance with the last two item.
1) No one of "SCNR", "SCNB" and "SCNG" exceeding 128
2) Confirm the item value 128 at least one item
8.
As a result above, input the sequential number of value to the
"SCNR", "SCNB" and "SCNG".
9.
Repeat the same step 5 thru 8 for the W/B 1 thru 4 after
setting the "0 WBNO" at each W/B number.
10. Input following signals from the Signal generator (VG-
828D).
1) All-white signal (255/255) input
Y (luminance)=45cd/m
2) 1/25Window (255/255) input
Y (luminance)=45cd/m
