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.

Abstract: Quantum dot layers and display devices including quantum dot layers are described. In an embodiment the quantum dot layer includes quantum dots (300) with metal oxide coatings (308) to adjust the spacing between adjacent quantum dots. In an embodiment, the metal oxide coatings may create a charge transporting matrix, be QD-LED compatible.
