Abstract
An LED device that includes electrodes patterned over a substrate; the pattern forming several first electrodes separated by inter-electrode spacers. One or more light-emitting layers are formed over the first electrodes. A patterned conductive layer is formed over the one or more light-emitting layers and over the first electrodes in regions external to the inter-electrode spacers. A continuous unpatterned conductive layer is formed over both the patterned conductive layer and the inter-electrode spacers. Finally, a combination of the patterned and continuous unpatterned conductive layers form a single, bi-layered, electrically continuous second electrode.
Claims8
An LED device, comprising:
- a) a substrate;
- b) a plurality of electrodes patterned over the substrate, the pattern forming a plurality of first electrodes separated by inter-electrode spacers;
- c) one or more light-emitting layers formed over the plurality of first electrodes;
- d) a patterned conductive layer formed over the one or more light-emitting layers and over the plurality of first electrodes in regions external to the inter-electrode spacers;
- e) a continuous unpatterned conductive layer formed over both the patterned conductive layer and the inter-electrode spacers;
- and
- f) wherein a combination of the patterned and continuous unpatterned conductive layers form a single, bi-layered, electrically continuous second electrode, and
- wherein the thickness of at least some of the patterned, conductive layer is different over at least some of the plurality of first electrodes than over others of the plurality of first electrodes.
