Abstract
The present disclosure provides a holographic reproduction device, a holographic reproduction system, and a holographic display system. The holographic reproduction device includes a first light source configured to provide first coherent light; at least one electrically addressed liquid crystal display panel configured to display a holographic interferogram, so that the first coherent light is diffracted when the first coherent light transmits through the holographic interferogram to present a holographic reproduction image. A liquid crystal material of the electrically addressed liquid crystal display panel includes smectic liquid crystal.
