An active matrix EL VGA display is reported with full grayscale using temporal voltage modulation of the phosphor. The exceptional brightness and dynamic range of the ZnS:Mn EL phosphor permits a new gray scale scheme. Digital gamma correction and an extended range of levels achieve 128 to 256 monotonic shades.
