==Raster addressing==

A '''raster addressed''' display (e.g., a [[CRT]]) works by scanning across the entire display in sequence while modulating control signal to activate each pixel as it is scanned. This display uses persistence of the pixel element (e.g., [[phosphor]]) to maintain the pixel state until the scan can visit that pixel again. There are are only three control signals required for this to work: a horizontal scan control signal, a vertical scan control signal, and an intensity control signal. Timing between these signals is very important, else the image on the screen will show artifacts.
