摘要:
A light emitting device for a display includes a substrate and first, second, and third LED sub-units, a first transparent electrode between the first and second LED sub-units and in ohmic contact with the first LED sub-unit, a second transparent electrode between the second and third LED sub-units and in ohmic contact with the second LED sub-unit, a third transparent electrode between the second transparent electrode and the third LED sub-unit and in ohmic contact with the third LED sub-unit, at least one current spreader connected to at least one of the first, second, and third LED sub-units, electrode pads disposed on the substrate, and through-hole vias formed through the substrate, in which at least one of the through-hole vias is formed through the substrate and the first and second LED sub-units.
