Abstract

A holographic display system, a holographic display method and an electronic device are provided. The holographic display system includes a backlight module configured to emit a backlight beam, a spatial light modulator configured to perform phase and amplitude modulations on the backlight beam, and a plurality of liquid crystal grating modules that are sequentially arranged in a first direction. Based on a polarization direction of incident light, a liquid crystal grating module is capable of changing or maintaining a propagation direction of the incident light. A first optical rotator disposed on a light-incident side of the liquid crystal grating module is capable of rotating the polarization direction of the incident light, to make at least one liquid crystal grating module change the propagation direction of the incident light, and at least one liquid crystal grating module do not change the propagation direction of the incident light within a preset duration.
