Abstract
Described are light emitting diode (LED) devices comprising a plurality of mesas defining pixels, each of the plurality of mesas comprising semiconductor layers, an N-contact material in a space between each of the plurality of mesas, a dielectric material which insulates sidewalls of the P-type layer and the active region from the metal. Each of the mesas is spaced so that there is a pixel pitch in a range of from 10 μm to 100 μm and dark space gap between adjacent edges of p-contact layer. The dark space gap may be less than 20% of the pixel pitch. The dark space gap may be in a range of from 4 μm to 10 μm.
