ABSTRACT:
A display device for displaying characters and graphic patterns by using a raster scan type cathode ray tube is disclosed. Clock frequencies applied to a parallel-to-serial converter for converting parallel character data to serial data and a parallel-to-serial converter for converting parallel graphic data to serial data are different from each other so that the number of dots displayed on the cathode ray tube in one-character display period for the character data is different from that for the graphic data.
