Abstract: A display system may include a light source that emits input light having a wavelength within a source wavelength range and an array of color conversion units overlapping a display area. A first set of color conversion units of the array of color conversion units may include a first color conversion medium that converts the input light to a first color of light having a wavelength within a first wavelength range that is different than the source wavelength range. The display system may also include a waveguide having an out-coupler that directs the input light from the light source toward the array of color conversion units. Various other devices, systems, and methods are also disclosed.

Abstract: A self-lit display panel includes a photonic integrated circuit payer including an array of waveguides and an array of out-couplers for out-coupling portions of the illuminating light through pixels of the panel. The self-lit display panel may include a transparent electronic circuitry layer backlit by the photonic integrated circuit layer; the two layers may be on a same substrate or on opposed substrates defining a cell filled with an electro-active material. The configuration allows for chief ray engineering, zonal illuminating, and separate illumination with red, green, and blue illuminating light.
