(3) Adjustment Map

(Automatic Adjustment)

1) The adjustment condition should be set by the Power On

key.

2) Perform the zero calibration of the Color Analyzer and

place the probe close to the display center.

3) Connect the communication cable (RS-232C).
4) Select the desired model of the adjustment program and

perform the adjustment.

5) After the adjustment is ended (check the OK sign), check

the adjustment condition for each mode of the set.
(Warm, Medium, Cool)

6) Disconnect the probe and the communication cable to end

the adjustment.

* The adjustment should be started with "wb 00 00" and

ended with "wb 00 ff", and the offset should be adjusted
when necessary.

1) The adjustment condition should be set by the Power On

key.

2) Press the ADJ of the R/C to enter into 'EZ-ADJUST'.
3) Select '10.TEST PATTERN' with the CH +/- key and press

the Enter key for 30 minutes or longer to perform the heat
run.

4) Perform the zero calibration of the Color Analyzer and fix

the sensor with the 10cm or less distance at the center of
the LCD module surface when adjusting.

5) Press the ADJ of the R/C to select '7.White-Balance' of the

Ez-Adjust and press the right arrow key(

G

) to enter into the

adjustment mode. (As soon as you press '

G

', the screen is

entered into the full white inner pattern.)

6) Fix one of the R/G/B gains to 192 and decrease the

remaining two gains to adjust not to exceed 192.

7) The adjustment is done at three white balances of Cool,

Medium and Warm.

* The inner pattern is used basically, and if it is not possible,

the adjustment can be done by selecting the HDMI input.
NONE, INNER or HDMI can be selected by the bottom
option at the Ez Adjust Menu 7.White Balance menu and it is

* Adjustment environment and reference

1) Environment illuminance

Adjust it to 10 LUX or less at the place where the light
source such as lamp should be blocked at maximum.

2) Probe location

: Maintain the Color Analyzer (CA-210) close to the

module surface by 10cm or less and keep the probe of
the Color Analyzer perpendicular to the module
surface (80°~ 100°).

3) Aging time

- Keep the power on after the aging start (with no power

off) to perform the heat run for 15 minutes or longer.
