5. Total Assembly line process
5.1. 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)
* The spec of color temperature and coordinate.
5.1.1. 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.
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
* W/B Table( Netcast4.0 Model)
CA210 : CH 14, Test signal : Inner pattern (80IRE)
Normal line - Standard color coordinate and temprature using
CA-1000(by H/R time)
Aging chamber line - Standard color coordinate and temprature
using CA-1000(by H/R time)
* When Model produce in Gumi Factory at Winter(Jan,Feb)
Normal line
* AUO, Sharp, CSOT use Model(If Cool spec 13000K)

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
