Abstract
Official abstract text for this publication.
The invention provides an organic light emitting diode (OLED), having a substrate, an anode layer of silver or gold, wherein the anode layer is treated with CF 4 plasma to enhance the hole injection of the semitransparent anode layer.
First claim
Opening claim text (preview).
We claim: 1. A bottom-emitting microcavity organic light-emitting diode (OLED) device, comprising: (a) a transparent substrate; (b) a semitransparent conductive anode layer including a metal comprising at least one of Ag, Au and an alloy thereof, formed over the substrate; (c) a plurality of emissive units disposed between the anode and a reflective and conductive cathode, wherein the emissive units comprise at least a hole-transport layer and a electron-transport layer, and…
