Abstract

THE LUMINOUS EFFICIENCY AND RADIANCE OF LIGHT EMILITING DIODES (LEDS) FABRICATED FROM ORGANIC EMISSIVE MATERIALS CAN BE INCREASED BY USING A MULTILAYER CATHODE INCLUDING A LOW WORK FUNCTION LAYER ANDA HIGH WORK FUNCTION HIGH REFLECTIVITY LAYER, IN COMBINATION WITH A HIGH WORK FUNCTION, HIGH REFLECTIVITITY ANODE MATERIAL IN THE DEVICE.
