Apparatus for displaying characters

DETAILED DESCRIPTION Accordingly, an object of the invention is to provide a display system with a single character generator for both sections or stations of a divided CRT screen.
To achieve the above object, there is provided an apparatus for displaying characters which divides a display screen of the raster scan type and supplies display information to the respective sides by using a mirror reflection, comprising: a programmable CRT controller; a refresh memory for storing coded data to be displayed in response to a refresh memory address obtained from the controller; raster address converting circuit means which receives the raster address from the controller and converts it to a converted raster address; multiplexer means for selecting the raster address from the controller and the converted raster address from the raster address converting circuit means on the basis of control information contained in the refresh memory address; a character generator for converting the coded data from the refresh memory into pattern data on the basis of raster address information from the multiplexer means; bidirectional shift register means which receives the pattern data from the character generator, determines a shift direction thereof on the basis of control information contained in the refresh memory address, and produces serial dot data; and a display unit for displaying the dot data from the bidirectional shift register.
