3) Press the IN-START key on R/C for adjustment.

[Fig.3]

4) Press  the 

(Vol.+) key to operate the set , then it

becomes automatically.

5) After downloading complete, the ‘OK’ word

appears.

6) Auto-RGB OK means adjustment is completed.

* Test Equipment

Color Analyzer (CA-210, CA-100+ / CH.9)

-> When you adjust LCD color temperature, on Color

analyzer (CA-210, CA-100+), you should use Channel 9
which is Matrix compensated (White, Red, Green, Blue
revised) by CS-1000 and adjust in accordance with
White balance adjustment coordinate which is specified
on the next.

* Color temperature standards according to CSM and Module.

* White balance adjustment coordinate and color temperature.

PC (for communication through RS-232C) -> UART
Baud rate : 115200 bps

* Connecting picture of the measuring instrument (On

Automatic control )

Inside PATTERN is used when W/B is controlled.
Connect to auto controller or push control R/C IN-START
-> Enter the mode of White-Balance, the pattern will come
out.

* Auto-control interface and directions
1) Adjust in the place where the influx of light like floodlight

around is blocked. (illumination is less than 10ux).

2) In case of PDP: Measure and adjust after sticking the

Color Analyzer (CA-100+, CA210 ) to the side of the
module. 

In case of LCD: Adhere closely  the Color Analyzer (
CA210 ) to the module less than 10cm distance, keep it
with the surface of the Module and Color Analyzer’s
Prove vertically.(80~100°).

3) Aging time

- After aging start, keep the power on (no suspension of

power supply) and heat-run over 15 minutes.

- In case of PDP, keep white pattern using inside pattern.
- In case of LCD, using ‘no signal’ or ‘full white pattern’ or

the others, check the back light on.

1) setup is done.

*** When press Power-on key, this point is automatically

setuped. Pattern Generator (MSPG-925F)

* One of R Gain / G Gain / B Gain should be kept on 80,

and others are controlled lowering from 80 

1) Press "power on°" of the control R/C, set heat run to

white by pressing 

, and heat run over 15 minutes 

(Set : RS-233 Host : PC, Baud Rate : 115200bps,

Download: Cortez).

2) Zero Calibrate CA-100+, and when controlling, stick the

sensor to the center of LCD module surface.

3) Double click In-start key on Controlling R/C and get in

‘white balance’.

4) Set test-pattern on and display inside pattern. Control is

carried out on three color temperature, COOL, MEDIUM,
WARM. (Control is carried out three times,)

5) When the R/G/B GAIN is 80 on OSD, it is the FULL

DYNAMIC Range of the Module. In order to control white
balance without the saturation of FULL DYNAMIC Range
and DATA, one of R Gain / G Gain / B Gain should be
kept on 80, and other two is controlled lowering from 80.

* Color Temperature: Cool, Medium, Warm
1. When R GAIN is set to 80

- Control G GAIN and B GAIN by lowering from 80. 

2. When B GAIN is set to 80

- Control R GAIN and G GAIN by lowering from 80.

3. When G GAIN is set to 80

- Control R GAIN and B GAIN by lowering from

192.

One of R Gain / G Gain / B Gain should be kept on
80, and adjust other two lower than 80.
(When R/G/B GAIN are all 80, it is the FULL

DYNAMIC Range of Module) 

1) Setting up like bottom figure(After setting white balance,

this is set)

(Setting: Press ADJ Key in the Adjust remocon.
