Abstract
A holographic display device and a display method thereof. The holographic display device comprises a backlight module and two liquid crystal modules. The backlight module is used for providing coherent light; the two liquid crystal modules are located on the light exit side of the backlight module, and the two liquid crystal modules are stacked; one of the two liquid crystal modules is used for performing amplitude modulation on incident light, and the other one is used for performing phase modulation on incident light. In this way, the complex amplitude of exit light is adjusted, and the quality of a reconstructed image is improved.
