vector display

a technology used for computer monitors that moved the electron beam in a CRT directly along the paths between specified points on the display, creating very sharp, smooth lines and requiring very little memory to refresh the display. Vector displays are mostly obsolete but were especially common for oscilloscopes and other scientific instruments and in older arcade games. They’ve been displaced by raster displays, which allow much more flexible images. Color is not possible in a vector display, though sometimes it is partially simulated by tinting regions of the monitor to give regions where images were colored differently.
