Patent ID: 7633218

Claim:
A light-emitting diode device, comprising: a) a substrate; b) a plurality of first electrodes formed in a pattern over the substrate in a first dimension; c) a plurality of first shadowing pillars, having a first height, and formed in a second dimension, orthogonal to the first dimension, over the substrate; d) one-or-more first light-emitting layer(s) formed over the first electrodes; e) a plurality of second electrodes formed in a pattern between the first shadowing pillars over the one-or-more first light-emitting layer(s); f) a plurality of second shadowing pillars, having a second height, and formed in the first dimension over the substrate, wherein the second height is greater than the first height; g) one or more second light-emitting layer(s) formed over the second electrodes; and h) a plurality of third electrodes formed in a pattern over the first shadowing pillars between the second shadowing pillars over the one-or-more second light-emitting layer(s).
