Christopher N King, Richard E Coovert: Thin film electroluminescent display with improved contrast. Planar Systems, Chernoff Vilhauer McClung & Stenzel, October 16, 1990: US04963788 (61 worldwide citation)

A TFEL device having improved contrast includes a laminate having a phosphor layer sandwiched between front and rear insulating layers placed upon a substrate supporting a set of front transparent electrodes. The rear set of electrodes are transparent or semitransparent so as not to reflect ambient ...

A highly efficient, AC-excited, blue light-emitting phosphor for solid-state thin-film electro-luminescent (TFEL) devices is comprised of strontium sulphide (SrS) host material doped with cerium fluoride (CeF.sub.3) acting as an emitter providing a source of photons. The blue SrS:CeF.sub.3 phosphor ...
