Random scan is a method in which the display is made by the electronic beam which is directed only to the points or part of the screen where the picture is to be drawn. The raster-scan process contrasts with the random-scan process used by plotters and calligraphic display systems to make line drawings. This accounts for the higher sophistication of the command electronics, which explains that the raster-scan solution has been rejected until recently except for a few high-cost high-quality displays (2).
