Abstract: A display system includes (i) a plurality of picture elements supported on a single semiconductor substrate and (ii) a backplane including electronic circuitry supported thereon and electronically connected with the picture elements. Each picture element includes a light steering optical element and an array of light emitting elements. The array of light emitting elements includes a first set, a second set, and a third set of inorganic LEDs that (i) are monolithically integrated on the single semiconductor substrate and (ii) emit, respectively, light at a first, a second, and a third wavelength, which are mutually distinct. The light steering optical element is configured for steering the light from the first set, second set, and third set of LEDs in a predetermined direction. The electronic circuitry is configured for individually driving each light emitting element of the array of light emitting elements.
