Colour 3D holographic display based on a quantum-dot-doped liquid crystal

Liquid crystals (LCs) doped with photo-sensitive materials exhibit large optical nonlinearity, which makes them attractive for holographic display. In this paper, we present a 3D holographic display based on a nematic LC doped with quantum dots (QDs). With this QD-doped LC, a fast response time of 8.46 ms is achieved. Using this fast-updated recording material, a video-rate 3D holographic display system is implemented, which provides vivid RGB colours and high brightness, and offers all depth cues correctly. In combination with optical multiplexing techniques, the presented system is capable of realising large-sized holographic display.
