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: A display may include light-emitting components such as light-emitting diodes on a transparent substrate. Conductive signal paths between the light-emitting components, driver integrated circuits for controlling the light-emitting components, and the light-emitting components themselves may be opaque. To mitigate diffraction artifacts caused by the opaque components, the opaque footprint of the display may be selected to include non-periodic portions. The non-periodic portions increase randomness and reduce periodicity within the opaque footprint, which mitigates perceptible diffraction artifacts when viewing the display. One or both of the component mounting portions and interconnect portions of the opaque footprint may be non-periodic. The component mounting portions may have random shapes. The interconnect portions may follow random paths between the component mounting portions.

Abstract: Methods and structures are described to facilitate the transfer of device layer coupons with controlled vertical position. In an embodiment, a plurality of device layer coupons is bonded to a receiving substrate with an adhesive layer, where distance between front surfaces of the plurality of device layer coupons and a bulk layer of the receiving substrate is controlled by a plurality of rigid mechanical spacers.

Abstract: Embodiments of the invention include a semiconductor light emitting diode (LED) attached to a top surface of a mount. A multi-layer reflector is disposed on the top surface of the mount adjacent to the LED. The multi-layer reflector includes layer pairs of alternating layers of low index of refraction material and high index of refraction material. A portion of the top surface in direct contact with the multi-layer reflector is non-reflective.
