Adjustment procedure
1. Use the XGA VESA (60) timing signal to input a
0.35Vp-p G primary color signal.
2. Measure the illumination at adjustment points No. 2
and No. 3.
The values should be:
No. 2 = Y2 [lux]
No. 3 = Y3 [lux]
3. Determine which of the No. 2 or No. 3 adjustment
point has the higher illumination and then adjust it
to match the one with the lower illumination.
For example, if Y2 > Y3, adjust No. 2 G: to set the
No. 2 illumination as follows.
Y2 = Y3 10 [lx]
This completes the G color adjustment.
4. Next, use the XGA VESA (60) timing signal to input
a 0.35Vp-p white signal.
5. Measure and make a note of the color coordinates
of adjustment point No. 1.
The values should be: x = x1, y = y1
Note:
When using the CL-100 (Color Differential Meter), it
is convenient to use the Delta mode. After
measuring the color coordinates of adjustment
point No. 1, hold down the [F] button on the front
and set the slide switch on the side to [ ] Delta.
After that, the differences from adjustment point
No. 1 will be displayed as the measurement values.
6. Next, measure the color coordinates of adjustment
point No. 2, and then adjust No. 2 A: and B: until
the color coordinates are as follows.
x = x1 0.01 , y = y1 0.01 (ANSI point color
uniformity)
7. Measure and adjust the color coordinates of
adjustment points No. 3 - No. 9 in sequence in the
same way, starting with the smallest signal.
8. Next, measure the color coordinates of adjustment
point No. 10, and then adjust No. 10 A: and B: until
the color coordinates are as follows.
x = x1 0.01 , y = y1 0.02 (corner color
uniformity)
9. Measure and adjust the color coordinates of
adjustment points No. 11 - No. 17 in sequence in
the same way, starting with the smallest signal.
10. This completes the normal color uniformity
adjustment. Adjust visually if local lack of color
uniformity still remains around the periphery of the
screen.
11. If there is local lack of color uniformity around the
periphery of the screen, adjust the color
coordinates of adjustment point No. 18 - No. 21
outside the worst side of the screen.
12. If there is local lack of color uniformity in the
corners of the screen, adjust the color coordinates
of adjustment point No. 22 - No. 33 outside the
worst corner of the screen.
