Abstract
Abstract An electroluminescent semiconductor device in which the drain of a MOSFET acts as the driver for a manganese doped zinc sulfide electroluminescent layer. The zinc sulfide layer is coated with a layer of metal which prevents the emission of light from the electroluminescent layer except through an aperture extending through the metal layer. Alternatively, the aperture is omitted and laser emission is induced from a semi-reflective end plate positioned on a side of the electroluminescent layer.
