Abstract: A sub-pixel unit for a reflective display includes a color filter including a tunable high contrast grating. The tunable high contrast grating reflects light within a first range of wavelengths, and the sub-pixel unit can exist in a first state and a second state, the first state reflecting at least one of (i) light within a different range of wavelengths, and (ii) light of a different intensity level, than the second state.
