Abstract

AbstractWe demonstrate a polarization‐independent, diffractive, liquid crystal microdisplay on a reflective 256×256 pixel silicon backplane using nematic liquid crystal polarization gratings. Striking results are observed in a single‐panel projector with remarkably simple optics, where the technology supports up to ∼75% throughput (reflectance) of unpolarized light, contrast ratios approaching 1000:1, and < 800 μs total switching time.
