ABSTRACT:
A graphic display apparatus in which the data to be displayed is stored as two types of data word, one type representing groups of increments of beam displacement of a beam displacement tube and the other representing differences between the data constituting a raster line and that of next succeeding line. The data for each line formed from the first type of words is temporarily stored in a line store while being displayed on the tube. The contents of the line store are modified according to any second type words received during the display period so as to convert the stored data into that for the next line to be displayed.
