Abstract: A system is provided for displaying alpha-numerical data on a cathode ray tube. A flicker-free, high resolution display is achieved by a repeating raster field displaced slightly from one another. This is achieved in one approach by using a modified repeat field technique in a 10 .times. 14 display and an associated 10 .times. 14 memory for each letter. Another approach employs a 5 .times. 7 memory in conjunction with logic circuitry producing a resolution equivalent to a 10 .times. 14 display by means of fillets generated at selected portions of the characters. The shape of individual characters is improved by selectively removing fillets from square corners of the character by using the presence of a black or illuminated area to inhibit the use of a fillet.
