GENERAL PRODUCT SPECIFICATION
Geometric distortions
It is acceptable that pincushion, trapezoid, r homboid,
rotation and various waves distortions must remain within
the limits of tolerance as in fig. 4,
½A½ , ½B½

The waviness of any vertical or horizont al shall be less
than 1.0 mm over a 50 mm distance.
Image non-linearity pattern with
10 equal blocks along horizontal axis,
8 equal blocks along vertical axis.

Mis -convergence
The maximum convergence error to be measured on a white
spot or white display line to represents the maximum distance
between the energy centers of any two primary colors. (See Fig. 6)
Mis-Convergence SPEC.
CRT Pitch
Focus check (with 68.7K/85Hz,1024 x 768 mode)
Generate "@" characters (pattern as fig 7) to cover entire of the picture
area (display size respect to fig. 1), adjust brightness control to 50% and
contrast control to obtain 25 FL @ 5 -block pattern, the characters should
be clearly identified in all display area.
condition : With full white pattern, set contrast control at max. and adjust
brightness control to get 30FL in center
the max. deviation to the rest of the s creen shall not exceed 25% of
entire screen with any point.
