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: Optical components such as components that emit light and components that detect light may be provided. Optical components that emit light may include displays having arrays of display pixels with respective light-emitting devices such as crystalline semiconductor light-emitting diodes. Optical components that detect light may include image sensors or other components with arrays of photodetectors. The light-emitting devices and photodetectors in the optical components may be overlapped by metalenses such as multielement metalenses. A multielement metalens may have a first metalens element formed from a first layer of nanostructures arranged and an overlapping second metalens element formed from a second layer of nanostructures. Light sources may be provided on a semiconductor and metalens nanostructures may be formed on an opposing surface of the semiconductor.

Abstract: An electronic device may provide image light to an eye box. The display may include a light source panel that emits the image light. A waveguide may direct the image light towards the eye box. An input coupler may couple the image light into the waveguide and an output coupler may couple the image light out of the waveguide. A color filter may be optically interposed between the light source panel and the output coupler. The color filter may filter the image light using a steep cutoff characteristic. The color filter may allow the image light to exhibit a desired color point while also allowing the light source panel to use light emitters having peak emission wavelengths that maximize the efficiency of the light emitters and thus the power efficiency of the device.
