4.3. White Balance Adjustment

4.3.1 Overview

(1)W/B adj. Objective & How-it-works

(2)Objective: To reduce each Panel’s W/B deviation

(3)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.

(4)Adj. condition : normal temperature

1)Surrounding Temperature : 25 ºC ± 5 ºC

2)Warm-up time: About 5 Min

3)Surrounding Humidity : 20 % ~ 80 %

4.3.2 Equipment

1)Color Analyzer: CA-210 (LED Module : CH 14)

2)Adj. Computer(During auto adj., RS-232C protocol is needed)

3)Adjust Remocon

4)Video Signal Generator MSPG-925F 720p/216-Gray (Model:217, Pattern:78)

-> Only when internal pattern is not available

A Color Analyzer Matrix should be calibrated using CS-1000

4.3.4. Adj. Command (Protocol)

<Command Format>

LEN CMD VAL CS

-LEN: Number of Data Byte to be sent

-CMD: Command

-VAL: FOS Data value

-CS: Checksum of sent data

-A: Acknowledge

Ex) [Send: JA_00_DD] / [Ack: A_00_okDDX]

A RS-232C Command used during auto-adj.

RS-232C COMMAND			Explanation
[CMD	ID	DATA]
wb	00	00	Begin White Balance adj.
wb	00	10	Gain adj.(internal white pattern)
wb	00	1f	Gain adj. completed
wb	00	20	Offset adj.(internal white pattern)
wb	00	2f	Offset adj. completed
wb	00	ff	End White Balance adj.(Internal pattern disappears)

Ex) wb 00 00 -> Begin white balance auto-adj. wb 00 10 -> Gain adj.

ja 00 ff -> Adj. data jb 00 c0

...

...

wb 00 1f -> Gain adj. completed

*(wb 00 20(Start), wb 00 2f(completed)) -> Off-set adj. wb 00 ff -> End white balance auto-adj.
