High-resolution meta-displays leveraging low-loss nonvolatile phase-change chalcogenides

Electrically switchable dual-view meta-displays with high-resolution, wide-gamut, and high-saturation features for dynamic image encryption and encoding are demonstrated by leveraging less-explored classes of low-loss optical phase-change chalcogenides, i.e., Sb 2 S 3 and Sb 2 Se 3 .
