Abstract
A TFEL edge emitter assembly has a TFEL edge emitter module composed of a substrate and an EL stack supported on the substrate and having a light-emitting front edge, and a covering of solid material overlying the EL stack and attached to the substrate. The solid covering produces a hermetical seal with the substrate which substantially encompasses the EL stack and provide an optically transparent medium having a refractive index between that of the EL stack and air.
