This paper discusses progress in the design of graphic displays, as seen from the viewpoint of the graphics system designer. In the first of three parts, the paper outlines the development of line-drawing displays, and explains why attention is presently focused on buffered transformation processors. The second part discusses raster-scan CRT displays, and compares several solutions to the problems of scan conversion and storage for refresh. The third part reviews some issues in the design of new display devices, and relates these to the functional characteristics of the graphic display.
