7. White Balance
* Notice
- Do the white balance adjustment under the 10LUX
- Before enter the white balance adjustment, have to change
- Before enter the white balance adjustment, have to change
AV mode.(not RF, Comp, RGB, HDMI)
- Before white balance, press the In-start key 2times and do
the reset like Fig.6
- Use the Torino inner pattern(216 gray pattern)
- To enter White-balance mode,press the IN-START key
- To enter White-balance mode,press the IN-START key
2times.
7-1. Test Equipment
(1) Color Analyzer (CA-100 or CA-210).
* Note : When using the Color Analyzer with PDP,
* Note : When using the Color Analyzer with PDP,
recommend the CA-100 more than CA-210.
If CA-100 can not available, it is also good th use
the CA-210
If CA-100 can not available, it is also good th use
the CA-210
(2) PC(for communication through RS-232C)
-> UART Baud rate : 115200.
(3) Pattern Generator(MSPG-925FA etc.)
7-2. Color temperature & Color Coordinates
Setting
(1) When adjusting the Color Temperature of PDP, Color
Analyzer CA-210(Matrix should be corrected through
CH10 of CS-1000) should be used. When CA-210 have
used, it don’t need to fit the CH10.
CH10 of CS-1000) should be used. When CA-210 have
used, it don’t need to fit the CH10.
(2) Adjust the Color Temperature based below adjustment
color coordinates.
(3) Even if CH9 of CA-210 is corrected with Matrix, there may
be many character of Module and Filter.
(4) Therefore Refer to the below Color Coordinates Target.
But, in case of WCG module, use the CH12 of CA-210.
W
Target Value CA-210(CH10), CA-100
(R/G/B gain and R/G/B offset Default values are different in
according to using module)
W
Target Value of Brightness, Color Coordinates, Color Temperature
7-3. Manual white Balance (INNER Pattern)
(For White Balance, Adjust twice, Cool and Warm)
(1) Execute CA-100, CA-210(10CH) or CA-100 Zero Calibration.
(2) Use torino inner pattern as below Fig.7, Supply 216Level
(2) Use torino inner pattern as below Fig.7, Supply 216Level
(85 IRE) full screen pattern
(3) Enter the White Balance adjustment mode by pressing the
INSTART key twice(White Balance) on R/C.
(4) Stick sensor to center of the screen and select each items
(Red/Green/Blue Gain and Offset) using
D
/
E
(CH+/-) key
on R/C.
(5) Adjust with R / G / B Gain using
F
/
G
(VOL+/-) key on R/C.
(6) Adjust it until color coordination becomes as below.
W
Color Temperature : Cool, Medium, Warm
(1) One of R/G.B Gain should be fixed at 80 and adjust two
Gain Value with decreasing the Default values from 80
1) When R Gain is Fixed at Default value(80)
- Adjust G gain and B gain with decreasing Default
values from 80
2) When B Gain is Fixed at Default value(80)
- Adjust R gain and G gain with decreasing Default
values from 80
3) When G Gain is Fixed at Default value(80)
- Adjust R gain and B gain with decreasing Default
values from 80
(2) R/G/B Gain and R/G/B Offset Default Value.
- Red Gain : 80
- Green Gain : 80
- Blue Gain : 80
- Green Gain : 80
- Blue Gain : 80
