Abstract

A reflective color display pixel has a top surface for receiving ambient light, and a plurality of sub-pixels including a first sub-pixel and a second sub-pixel. The first sub-pixel has a luminescent layer for absorbing a portion of the ambient light and emitting light of a first color. The second sub-pixel has a color tunable reflector for reflecting the ambient light in a selected band.
