White balance adjustment coordinate and color temperature

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

(On Automatic control )

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

(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  

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

power supply) and heat-run over 5 minutes.

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

the others, check the back light on.

Auto Adjustment Map(RS-232C)

1) Zero Calibrate CA-100+ / CA-210, and when controlling,

stick the sensor to the center of PDP module surface.

2) Press the ADJ KEY on R/C and enter EZ ASJUST

Select “2. White Balance” and press 

G

(VOL +)

Set test-pattern on and display inside pattern. 

3) Control is carried out on three color temperatures, COOL,

MEDIUM, WARM. 
(Control is carried out three times)

<Temperature: COOL>

- R-Cut/ G-Cut / B-Cut is set to 64
- Control R-Gain and G-Gain.
- Each gain is limited to 192

<Temperature: MEDIUM>

- R-Cut/ G-Cut / B-Cut is set to 64
- Control R-Gain and G-Gain.
- Each gain is limited to 192

<Temperature: WARM>

- R-Cut/ G-Cut / B-Cut is set to 64
- Control G-Gain and B-Gain.
- Each gain is limited to 192
