ABSTRACT:
Alphanumeric characters having borders of different color or brightness from the body of the characters are generated on a raster scan display device. Signals are generated for forming a first character having size equal to the character and borders. A second, smaller character is generated from the signals of the first, by appropriately blanking portions of the first character signals. The first and second character signals are arranged to produce centered, overlapping images of different colors or brightnesses on the display device.
