AC Timing
The AC timings of frame inversion AC drive, 3-field interlaced drive, and n-raster-row inversion drive are
illustrated as follows. In case of frame inversion AC drive, alternation occurs at the completion of drawing
one frame, followed by a blank, which lasts for 16H periods. AC Timing
The AC timings of frame inversion AC drive, 3-field interlaced drive, and n-raster-row inversion drive are
illustrated as follows. In case of frame inversion AC drive, alternation occurs at the completion of drawing
one frame, followed by a blank, which lasts for 8H periods. In this case, all the outputs from the gate are
Vgoff outputs. In case of interlaced drive, alternation occurs at the completion of drawing one field,
followed by a blank. The total period of the blanks in one frame amounts to 8 period. In case of n-raster-
row, a blank lasting 8H period is inserted after drawing a full screen.
