6. Final Assembly Adjustment
6.1. White Balance Adjustment
6.1.1. Overview
6.1.1.1. 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.
■ Case : Cool Mode
- To adjust the white balance without the saturation, G gain
should be adjust at least 172 and change the others (R,B
Gain)
* When R or B gain is over 255, G gain can be adjust
below 172)
■ Case : Medium / Warm Mode
- To adjust the white balance without the saturation, Fix the
one of R/G/B gain to 192 (default data) and decrease the
others.
(3) Adj. condition: normal temperature
- Surrounding Temperature: 25±5 ºC
- Warm-up time: About 5 Min
- Surrounding Humidity: 20% ~ 80%
- Before White balance adjustment, Keep power on status,
don’t power off
6.1.1.2. Adj. condition and cautionary items
(1) Lighting condition in surrounding area surrounding lighting
should be lower 10 lux. Try to isolate adj. area into dark
surrounding.
(2) Probe location: Color Analyzer (CA-210) probe should be
within 10cm and perpendicular of the module surface
(80°~ 100°)
(3) Aging time
- After Aging Start, Keep the Power ON status during 5
Minutes.
- In case of LCD, Back-light on should be checked using no
signal or Full-white pattern.
6.1.2. Equipment
(1) Color Analyzer: CA-210 (NCG: CH 9 / WCG: CH12 / LED:
