ORGANISCHE LEUCHTVORRICHTUNG MIT VERBESSERTEM LICHTEXTRAKTIONSWIRKUNGSGRAD

摘要

An enhanced light extraction organic light emitting device (OLED) (103) has transparent substrate (10), light scattering layer (12) over first surface of substrate, transparent first electrode layer over light scattering layer, organic electroluminescent (EL) element (30) over first electrode layer. The OLED has organic layer(s) and light emitting layer(s) in which light is produced, and transparent second electrode layer over organic EL element. Independent claims are also included for enhanced light extraction OLED devices.
