ABSTRACT:
A high density LED array with semiconductor interconnects includes a plurality of layers of material stacked on a substrate including a conductive layer, a first carrier confinement layer, an active layer, and a second carrier confinement layer. The layers are separated into isolated LEDs in a matrix of rows and columns with the conductive layer connecting a first electrode of each LED in a column to a first electrode of each other LED in the column. Row conductors connect a second electrode of each LED in a row to a second electrode of each other LED in the row and column conductors are connected to the conductive layer of each column.
