Total Assembly line process

Adjustment Preparation

# W/B Equipment condition

CA210: LED → CH14, Test signal: Inner pattern (80IRE)

# Above 5 minutes H/run in the inner pattern. ("Power on" key of Adjustment remote control)

W/B adj. Objective & How-it-works
(1) Objective: To reduce each Panel’s W/B deviation
(2) How-it-works: When R/G/B gain in the OSD is at 192, it means the panel is at its Full Dynamic Range.
In order to prevent saturation of Full Dynamic range and data, one of R/G/B is fixed at 192, and the other two is lowered to find the desired value.
(3) Adj. condition: normal temperature
> Surrounding Temperature: 25 ± 5 °C
> Warm-up time: About 5 Min
> Surrounding Humidity: 20% ~ 80%
> Before White balance adjustment, Keep power on status, don’t power off.

If Model is POLA model:

Case: Cool Mode

# Purpose: Adjust the color temperature to reduce the deviation of the module color temperature.

# Principle: To adjust the white balance without the saturation, Fix the G gain to 172 (default data) and change the others ( R/B Gain ).

# Adjustment mode: mode - Cool

Case : Medium / Warm Mode

# Purpose : Adjust the color temperature to reduce the deviation of the module color temperature.

# Principle: To adjust the white balance without the saturation, Fix the one of R/G/B gain to 192 (default data) and decrease the others.

# Adjustment mode: Two modes - Medium / Warm.

Manual W/B process using adjusts Remote control.> Colour Temperature: COOL, Medium, Warm> One of R Gain/ G Gain/ B Gain should be kept on 0xC0, and adjust other two lower than C0. (When R/G/B Gain are all C0, it is the FULL Dynamic Range of Module)> after enter Service Mode by pushing “ADJ” key,

> Enter White Balance by pushing ►key at “9. White Balance”.

> For manual adjustment, it is also possible by the following sequence

(1) Set TV in Adj. mode using POWER ON

(2) Zero Calibrate the probe of Colour Analyser, then place it on the centre of LCD module within 10cm of the surface

(3) Press ADJ key => EZ adjust using adj. R/C => 8. White Balance then press the cursor to the right (KEY►).   When KEY►is pressed 206 Gray internal pattern will be displayed.

(4) Adjust Cool modes

1) Fix the one of R/G/B gain to 192 (default data) and decrease the others. (If G gain is adjusted over 172 and R and B gain less than 192 , Adjust is O.K.)

2) If G gain is less than 172, Increase G gain by up to 172, and then increase R gain and G gain same amount of increasing G gain.

3) If R gain or B gain is over 255, readjust G gain less than 172, Conform to R gain is 255 or B gain is 255

(5) Adjust two modes (Medium/Warm) 

Fix the one of R/G/B gain to 192 (default data) and decrease the others.

(6) Adj. is completed, Exit adjust mode using “EXIT” key on Remote control.

# If internal pattern is not available, use RF input In EZ Adj. menu

9. White Balance, you can select one of 2 Test-pattern: ON, OFF. Default is inner (ON).  

By selecting OFF, you can adjust using RF signal in 206 Gray pattern Balance by pushing ► key at “9. White Balance”

CASE Cool
First adjust the coordinate far away from the target value(x, y).
1) x, y > target
i) Decrease the R, G.
2) x, y < target
i) First decrease the B gain,
ii) Decrease the one of the others.
3) x > target, y < target
i) First decrease B, so make y a little more than the target.
ii) Adjust x value by decreasing the R.
4) x < target, y > target
i) First decrease B, so make x a little more than the target.
ii) Adjust x value by decreasing the G.

How to adjust

1) If G gain is adjusted over 172 and R gain and B gain less than 192, Adjust is O.K.

2) If G gain is less than 172, increase G gain by up to 172, and then increase R gain and B gain same amount of increasing G gain.

3) If R gain or B gain is over 255, Readjust G gain less than 172, Conform to R gain is 255 or B gain is 255.

CASE Medium / Warm

First adjust the coordinate far away from the target value(x, y).

1) x, y > target

i) Decrease the R, G.

2) x, y < target

i) First decrease the B gain,

ii) Decrease the one of the others.

3) x > target, y < target

i) First decrease B, so make y a little more than the target.

ii) Adjust x value by decreasing the R

4) x < target, y > target

i) First decrease B, so make x a little more than the target.

ii) Adjust x value by decreasing the G

* After You finish all adjustments, Press “In-start” button and compare Tool option and Area option value with its BOM, if it is correctly same then unplug the AC cable.  If it is not same, then correct it same with BOM and unplug AC cable.  For correct it to the model’s module from factory JIG model.
* Push the “IN-STOP KEY” after completing the function inspection.
