2-2 WHITE Balance Coordinates

2-2-1 PS42D4S White Balance Adjustment

1. W/B Adjustment is required for the following six modes : DVI ’ Component(1080i) ’ Component(720p) ’ PC ’ VIDEO (Video port) ’ VIDEO (Graphic port)

2. Adjustment Method (Signal equipment : MSPG-925LTH, Measurement equipment : CA210)

■ MSPG-925LTH

Equipment that outputs analog and digital signals simultaneously

(Analog / Digital signal output / TV signal output (S-Video included) / HDTV signal output)

-. Digital Serial : TMDS (DVI24, SiI160) + DVI-I (Analog, Digital)

-. Monitor Signal (Analog): R, G, B, HS, VS, CS

-. TV Signal (CVBS) : NTSC M, NTSC J (7.5 IRE On/Off) (BNC or RCA), PAL B, D, G, H, I, PAL M, Nc

-. D-TV Signal (1080i, 720p, 480p)

♣

MSPG-925 is used to adjust the W/B

■ CA210 : Color Analyzers adjusting brightness, chromaticity and etc.

-. R.G.B monochrome correction, brightness and gamma character adjustment

-. White Balance and flickering measurement

(1) Adjust the TV by varying the panel values and the video DNIe register in order th determine the reference W/B

with a DVI input.

(2) For Component mode, adjust the register of AD9883 to align the DTV signal to the DNIe and logic panel value .

(At this time, do not adjust the gain of AD9883 ’ the Highlight W/B does not need to be adjusted since its deviation falls within valid distribution range.)

(3) PC adjustment is same as Component adjustment.

(The offset can be applied to the values obtained through DTV adjustment. However, additional adjustment is required for Y, Cb, and Cr, since PC processes R, G, and B signals.)

* Attention for Component/PC adjustment

- Load the Auto color pattern. (Pattern #21)

♣

Auto color pattern appears as black and white.

problems may occur if pattern #21 or similar

is not used.

- Excute factory mode auto color to adjust gain and offset.

- Load the Toshiba Pattern.(Pattern #16) and then adjust W/B.

♣

When factory mode auto color is executed, gain and

offset value is adjusted automatically.

Alignment and Adjustments

Samsung Electronics 2-3

(4) Video adjustment should be performed with the Toshiba pattern in RF video mode.

The adjustment should be the same as in step 1. Also, the video signal uses the video port when there is no other input signal. However, the signal uses the graphic port in PIP mode, which includes other input signals (PC, DVI, Component, etc.), Video adjustment should be performed with Video port and Graphic port separately.

* Thus, Micom saves the W/B data separately for each memory mode of the block (See the block diagram given below) during

W/B adjustment.
