Claim 16:
17. A light emitting structure comprising:
a substrate;
a group of conductive contact pads on the substrate, wherein each conductive contact pad is coupled to a corresponding driving transistor in the substrate;
an insulating layer over the substrate;
a group of bank openings in the insulating layer, each bank opening exposing a corresponding conductive contact pad;
a group of vertical light emitting diode devices on the group of conductive contact pads and within the group of bank openings;
wherein each vertical light emitting diode device in the group of vertical light emitting diode devices includes a micro p-n diode that includes one or more layers based on II-VI materials or III-V materials, and each vertical light emitting diode device in the group of vertical light emitting diode devices has a maximum width of 1 μm-100 μm;
a sidewall passivation layer formed around sidewalls of the group of vertical light emitting diodes devices;
a top conductive contact layer spanning over the sidewall passivation layer and the group of vertical light emitting diode devices, and in electrical contact with the group of vertical light emitting diode devices; and
a group of laterally separate reflective bank layers within the group of bank openings in the insulating layer.
