Abstract:
A light emitting diode (LED) array may include a first pixel and a second pixel on a substrate. The first pixel and the second pixel may include one or more tunnel junctions on one or more LEDs. The LED array may include a first trench between the first pixel and the second pixel. The trench may extend to the substrate.
