ABSTRACT:
A display unit useful for displaying graphical information and specifically for composing items to be printed on a page. The display unit includes a dot matrix screen and a display memory for storing the information to be displayed. An addressing register identifies memory locations in a sequence starting at location established by a begin display register. The starting location is transferred to the addressing register each time the display unit reaches a first dot location in the display unit. If the starting location is changed, an image corresponding to the item stored in the memory moves on the screen as a unit. Two or more memories can be interconnected to enable a relative motion between images corresponding to the items stored in each display memory.
