The invention is directed to systems, methods and computer program products for increasing the power efficiency of a display. An exemplary system includes a transflective display that is operable in either a transmissive mode or a reflective mode, and an illumination source with one or more distinct peaks in the illumination source's transmission spectrum, wherein light from the illumination source is directed towards the transflective display during the transmissive mode of operation. For the transmissive mode of operation, the transflective display's transmission spectrum is configured to substantially match the illumination source's transmission spectrum such that one or more narrow passbands in the transflective display's transmission spectrum substantially overlap with the one or more distinct peaks in the illumination source's transmission spectrum. For the reflective mode of operation, the transflective display's reflection spectrum is substantially inversely related to the transflective display's transmission spectrum.
