Dielectrics for bright EL displays

Abstract

Electroluminescent (EL) display design for high brightness is discussed. Single-layer and stacked dielectrics based on aluminum oxide, tantalum oxide, and silicon oxynitride are compared, and total stack designs are optimized for high brightness and manufacturability. Brightness values of 1 fL/Hz at V/sub t/+30 V have been achieved.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
