Paper Abstract

A high contrast emitter using AC thin film electroluminescence has been developed in which an absorbing black backing is in optical contact with the transparent emitter. The unique features of this development over the previous state of the art is preservation of the steep brightness-voltage characteristics such as required for matrix addressed displays and provision for a pinhole open circuit failure mechanism so that long life emitters can be achieved.
