6.4.9 REVCLDLY Adjustment
Conditions:
Input:
PC
PC input signal: VG-Prog. No. 856
XGA 60Hz
Test pattern:
CROSS
(R, G, and B colors and all white)
Gray scale
(R, G, and B colors)
Set adjustment values to the upper level than the point where there is jitter on the
vertical lines or the lower level. Choose the level where vertical lines are less tinted
in the all white crosshatch pattern.
Requirements:
•
In the image flipped vertically, there is no jitter on the vertical lines in the R, G, and
B crosshatch patterns.
•
There is no intensity difference between the vertical lines and the horizontal lines.
•
The width of the vertical lines is within the double of a pixel’s.
•
The vertical lines on the far-right and far-left portion of the projected image are
displayed.
•
Increase the adjustment value gradually from the initial data with
LCD1(CXA/6050) CLDLY
operation to check the point where there is jitter on the
vertical lines. Select the adjustment value among the values of +/- 20 or more from
the point, and then verify that there is no jitter on the vertical lines in each of RGB
colors. And verify that the vertical lines are not tinted in the all white crosshatch
pattern.
•
Next, in the gray-scale pattern, adjust CLDLY to minimize the faint vertical stripes.
