ABSTRACT:
A light-emitting diode device includes a substrate, and numerous first electrodes formed in a pattern over the substrate in a first dimension. Numerous first shadowing pillars, having a first height, are formed in a second dimension, orthogonal to the first dimension, and over the substrate. One-or-more first light-emitting layer(s) are formed over the first electrodes. Numerous second electrodes are formed in a pattern between the first shadowing pillars over the one-or-more first light-emitting layer(s). Numerous second shadowing pillars, having a second height, are formed in the first dimension over the substrate, wherein the second height is greater than the first height. One or more second light-emitting layer(s) are formed over the second electrodes; and numerous third electrodes are formed in a pattern over the first shadowing pillars, between the second shadowing pillars, and over the one-or-more second light-emitting layer(s).
