P‐111: Reflective Display Based on Total Internal Reflection and Grating‐Grating Coupling

We 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.
