ABSTRACT:
A character generator (14) applies character columns in a standard 5.times.7 or similar matrix form to a multi-digit dot matrix display (12). Inhibition circuitry (33), (23) eliminates all character columns containing no character dots. Additional circuitry (19), (33) ensures that there will be one blank column between adjacent characters. This arrangement increases the legibility of the display and enables more characters to be displayed in the same space.
