Abstract

An assembly corresponding to a pixel includes sub-assemblies that each correspond to a sub-pixel of the pixel. At least one of the sub-assemblies includes a luminescent fluid, black particles and a mirror. The luminescent fluid converts wavelengths of light less than a conversion wavelength of the sub-assembly to the conversion wavelength. The black particles are positionable within luminescent fluid in accordance with a color to be displayed by the assembly. The mirror is disposed at a bottom end of the sub-assembly.
