Line 155:
Practically all modern graphic displays are raster-mode, descended from the picture scanning techniques used for [[television]], in which the visual elements are a rectangular array of [[pixel]]s. Since the raster image is only perceptible to the human eye as a whole for a very short time, the raster must be refreshed many times per second to give the appearance of a persistent display. The electronic demands of refreshing display memory meant that graphic terminals were developed much later than text terminals, and initially cost much more.{<ref>{{cite web
