*Notice 

- Do the white balance adjustment under the 10LUX.
- Before white balance,press the In-start key 2times and do

the reset like Fig1 

- Use the cortez inner pattern(216 gray pattern)  

- To enter White-balance mode,press the IN-START key

2times 

=> Caution :   - System control RS-232 Host should be "PC"

for adjustment

* Test Equipment 

- Color Analyzer ( CA-210)
- PC (for communication through RS-232C)  => UART

Baud rate : 115200

- Pattern Generator (MSPG-925FA etc.)

* Color Temperature & Color Coordinates Setting

: When adjusting the Color Temperature of LCD, Color

AnalyzerCA-210(Matrix should be corrected through CH9
of CS-1000) should be used.
Adjust the Color Temperature based below adjustment
color coordinates.
Even if CH9 of CA-210 is corrected with Matrix, there may
be many character of Module and Filter.
Therefore Refer to the below Color Coordinates Target.
But,in case of WCG module,use the CH12 of CA-210.

1) Execute CA-210(9CH) Zero Calibration
2) Execute the SET Heat Run for 30minutes
3) Use cortez inner pattern as below Fig. 4, Supply 216Level

(85 IRE) full screen pattern 

4) Enter the White Balance adjustment mode by pressing the

INSTART key twice(White Balance) on R/C.

5) Stick sensor to center of the screen and select each items

(Red/Green/Blue Gain and Offset) using  

/

(CH+/-) key

on R/C.

6) Adjust with R / G / B Gain using 

/

key on R/C.

7) Adjust it until color coordination becomes as below. 

*Color Temperature : Cool, Medium, Warm

One of R/G.B Gain should be fixed at 80 and adjust two Gain
Value with decreasing the Default values from 80.
-When R Gain is Fixed at Default value(80)

Adjust G gain and B gain with decreasing Default values from 80

-When B Gain is Fixed at Default value(80)
Adjust R gain and G gain with decreasing Default values from 80
-When G Gain is Fixed at Default value(80)
Adjust R gain and B gain with decreasing Default values from 80

R/G/B Gain and R/G/B Offset Default Value
Red Gain :  80 ,    Green Gain :  80,     Blue Gain : 80
