2-11. GREEN REGISTRATION ADJUSTMENT
GREEN CENTER, GREEN SIZE
The sizing and centering that was performed in the previous section
(section 2-10) should have correctly sized and centered the green CRT.
The sizing and centering (coarse adjustment mode) of the red and blue
CRTs in following sections are performed so that the red and blue
patterns overlay the green pattern as close as possible prior to the fi ne
mode adjustments. The fi ne-mode adjustments are made for all 3 colors
so that the cross-hatch lines are straight vertically and horizontally, and
the linearity and convergence is correct.
