Abstract:
Light emitting structures and methods of fabrication are described. In an embodiment, LED coupons are transferred to a carrier substrate and then patterned to LED mesa structures. Patterning may be performed on heterogeneous groups of LED coupons with a common mask set. The LED mesa structure are then transferred in bulk to a display substrate. In an embodiment, a light emitting structure includes an arrangement of LEDs with different thickness, and corresponding bottom contacts with different thicknesses bonded to a display substrate.
