Abstract

AbstractWe report on a novel reflection‐type display based on total internal reflection and grating‐grating coupling fabricated in H‐PDLC materials. In this display, two symmetric slanted gratings are temporally multiplexed into a single film. A narrowband light is selected and diffracted from two coupled Bragg gratings creating a reflected image. These holographic pixels have switching voltages that are at least one‐half that of H‐PDLC reflective displays reported in the literature.
