85‐5: Late‐News‐Paper: Real Time Dynamic Holographic Display Based on Perovskite Doped Liquid Crystal

Abstract

Holographic display, which can completely reconstruct phase and amplitude information, is considered as an ideal true threedimensional display technology. In this work, liquid crystal doped with perovskite (CsPbBr3) works as the photorefractive material and forms diffraction grating under the interference light beams. The dependences of diffraction efficiency and response time on doping concentration, recording beam power and applied voltage are investigated. A maximum first-order diffraction efficiency of 18% has been achieved under a low electric field intensity of ~0.5 V/ m and the shortest grating build up time is as low as 5.5 ms. The system can realize a real-time dynamic display with 60 Hz refresh rate.
