5) Input the Gray pattern corresponding to the second lumi-
nance and change the second adjustment mode R/G/B
data value of Gamma adjustment item so that the R/G/B
data value to be same white balance with 1) and right to
the second luminance (measured in clause 3)
6) Input pattern signal with same method above and change
the Gamma R/G/B data value of corresponding level and
make same luminance with 3) and white balance with 1).

ET7050 IC through measurement equipment of optics.
Adjust screen coordinates data to adjust the color unifor-
mity of max point.
At this time, make sure that deviation is +5~-5% and stan-
dard is color coordinate of center.
3) Output the 16th VDP Test Pattern signal(7050 MID 570) of
No. 4 sub adjustment item(middle adjustment).
Read the white coordinates and communicate 3 line with
ET7050 IC through measurement equipment of optics.
Adjust screen coordinates data to adjust the color unifor-
mity of mid point.
At this time, make sure that deviation is +5~-5% and stan-
dard is color coordinate of center.
