Classification: CPC H  F | IPC F  H

Claim 5:
6. An LED array comprising:
a plurality of pixels, each pixel separated from an adjacent pixel by a trench extending from a p-type semiconductor layer to a distal surface of an n-type semiconductor layer;
an n-type contact in the trench;
the n-type semiconductor layer disposed on an active layer on the p-type semiconductor layer;
a wavelength converting layer on the n-type semiconductor layer on a surface opposite the active layer;
a p-type contact on the p-type semiconductor layer; and
one or more passivation layer extending from the p-type semiconductor layer to the n-type semiconductor layer and separating the n-type contact from the active layer and the p-type layer, the one or more passivation layer extending at least partially on a sidewall of the n-type semiconductor layer,
wherein the n-type contact extends to the wavelength converting layer and provides at least partial optical isolation between each pixel.
