1.4.4 Display of VC2-Specified Characters

When the displayed character control command specifies the VC2 channel for a character, that character is not output

to the RGB or VC1 channel (display for the RGB and VC1 channels is usually the same as when display-off data is writtenNote).

If background display (overall/minimum) is specified for the RGB or VC1 channel, no background is displayed for those

characters for which the VC2 channel has been specified.

Note In some cases, the display will differ slightly from the display-off data.

Solid data: Character for which all 12 × 18 dots are filled

• When display-off data is displayed for the RGB, VC1, or VC2 channel

If a character adjacent to the display-off data is rimmed or has a

background, the rim or background encroaches into the area for the display-

off data by one dot (minimum size). (The rim encroaches only at the filled

dots at the left or right edge of the rimmed character.)

• Display of VC2-specified character area 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 (mini-

mum size). If the adjacent character has a background, however, the

background does not encroach into the VC2-specified character area.

• Display of VC2-specified character area for the VC2 channel

If a rimmed VC2-specified character is adjacent to another VC2-specified

character, the rim encroaches into the area for the latter VC2-specified

character. The background does not encroach into the adjacent area (The

rim encroaches only at the filled dots on the left or right edge of the rimmed

character).
