Abstract
PURPOSE: To improve expression performance on a screen by increasing the degree of freedom by giving variety to combination between expanded characters, tables and figures, and basic characters or basic characters itself by making it possible to display characters at a boundary between picture elements.
CONSTITUTION: An indication code, if interposed in data read out from refresh memory 1 being shifted by a half line, is detected by decoder 2 and various following control is performed by row-shift controller 3. Codes of characters and a variable pattern, on the other hand, are inputted to pattern generator 4, which outputs display pattern data. In this case, line address counter 6 shifts a line address to be supplied to pattern generator 4 as much as a half line by a selective signal from row- shift controller 3. Consequently, characters and the variable pattern are shifted longitudinally exactly by a half line.
