2-2 WHITE Balance Coordinates

2-2-1 PS42P4A1 White Balance Adjustment

1. W/B Adjustment is required for the following four modes: DVI-> COMPONENT-> PC->VIDEO

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

(1) Adjust the target set by adjusting the panel logic and the video DNIe adjustment register in

order to determine the referential W/B of the panel with a DVI input, which is the full digital path.

(2)For Component adjustment, adjust the adjustment register of AD9883 to align the DTV signal

to the DNIe and logic panel value which was fixed with a DVI adjustment so that they are in effect considered to be the same signals. (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 of Component since PC processes R, G, and B signals.)

* Attention for Component/PC adjustment

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

- Excute Auto color of factory mode to adjust gain and offset.

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

(4)Video adjustment is performed with the Toshiba pattern (in-house signal) and differs from the VG828 signals in the above

three modes. Hence, it should be performed with the same method of (1) DVI adjustment. Also, 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.
