ABSTRACT:
A circuit for controlling information on a display includes two character generators. Each character generator is coupled to a row counter and a character latch which latches character information. The row counter is energized by line synchronization information. A width generator is coupled to both the character latch and a counter. Two shift registers are connected respectively to the first and second character generators and to a means for generating output signals for application to the display. The counter coupled to the width generator has its output signals applied to the character latch and to the output signal generating means for the display.
