1.5 OUTPUTTING BACKGROUND

The figures below show the screen display when minimum background or overall background is specified for each output

channel in RGB+VC1+VC2 mode.

Remarks 1. The above figures are only examples. Actually, the background can be controlled independently for each

output channel (only in RGB+VC1+VC2 mode), for example, by applying background (overall/minimum) for

the RGB channel but not for the other channels.

2. No background is applied to the VC2-specified areas for the RGB or VC1 channel. If a character adjacent

to a VC2-specified character is rimmed, the rim encroaches into the area for the VC2-specified character

by one dot (minimum size) only at the filled dots at the left or right edge of the area of the rimmed character,

in the same way as for display-off data. The background, however, does not encroach into the adjacent

area.
