Dynamic direct-writing optical holographic display based on quantum-dot-doped liquid crystal

ABSTRACT

In this paper, we propose a dynamic direct-writing optical holographic display system based on quantum-dot-doped liquid crystal (QDDLC). Instead of using two-beam interference to generate the desired holographic patterns, computer-generated hologram was directly generated by a spatial light modulator (SLM) and projected to the QDDLC sample. Employing only one recording beam, the proposed system greatly simplifies the optical system complexity and eliminates the influence of environmental disturbance. We investigate the factors that affect the diffraction efficiency and response time of the QDDLC in the direct-writing system and implement a dynamic holographic 3D display refreshed at 30 Hz.
