Abstract (en)
The present invention is directed to novel AC thin film electroluminescent display devices employing a protective dielectric stripe along the edges of the transparent electrode (or conductor). In particular, the present invention is directed to an AC thin film electroluminescent display device comprising: a multilayer stack including a first dielectric layer; a phosphor layer; and a second dielectric layer; situated on a glass substrate which includes parallel stripes of etched transparent conductors; said multilayer stack further including a protective stripe of dielectric material placed at least along the edges of the transparent conductors. The present invention is also directed to a method for protecting an AC thin film electroluminescent display device against premature breakdown at the edges of the transparent conductors. This protection is achieved by depositing a stripe of dielectric material along the edges of the transparent conductors.
