58‐3: Switchable Liquid‐Crystal Phase Grating with Rainbow‐Free Hazy States

Abstract

Novel flower‐shaped liquid crystal grating design was proposed to get a transparent display with the rainbow‐free hazy state. In transparent state, it exhibits 81.23 % of transmittance. In hazy state, it displays 74.6% of haze with crossed flower‐shaped liquid crystal grating. When the LC grating is used as a mirror display, the SCE of the mirror display are 0.012% and 32.43% in mirror and hazy state with a contrast of 2702.5.
