5.2.5. Green Eye Inspection Guide
(Step 1) Turn on the TV set.
(Step 2) Press “EYE” button on the Adjustment remote
controller.
(Step 3) Block the Intelligent Sensor module on the front C/A
about 6 seconds. When the “Sensor Data” is lower
than 20, you can see the “OK” message => If it
doesn’t show “OK” message, the Sensor Module is
defected one. You have to replace that with a good
one.
(Step 4) After check the “OK” message come out, take out
your hand from the Sensor module. => Check
“Backlight” value change from “0” to “100” or not. If it
doesn’t change the value, the sensor is also defected
one.
5.3. Manual White balance Adjustment
5.3.1. 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
1) Surrounding Temperature: 25 ± 5
ºC
2) Warm-up time: About 5 Min
3) Surrounding Humidity: 20% ~ 80%
4) Before White balance adjustment, Keep power on status,
don’t power off
5.3.2. 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
1) After Aging Start, Keep the Power ON status during 5
Minutes.
2) In case of LCD, Back-light on should be checked using
no signal or Full-white pattern.
5.3.3. Equipment
(1) Color Analyzer: CA-210 (NCG: CH 9 / WCG: CH12 / LED:
CH14 / OLED : CH : 17)
(2) Adj. Computer (During auto adj., RS-232C protocol is
needed)
(3) Adjust Remocon
(4) Video Signal Generator MSPG-925F 720p/204-Gray
(Model: 217, Pattern: 49)
※ Color Analyzer Matrix should be calibrated using CS-1000
