Abstract: A three-dimensional (3D) holographic display system includes a projector that generates an image with a form of spatially varying modulation on a light beam; holographic processor that performs a holographic method on the image generated by the projector; and memory device that stores holographic data generated in a process of performing the holographic method by the holographic processor. An amplitude of a light field is adaptively replaced by the holographic processor according to significance of respective areas of the image.

Abstract: A display module is provided. A light source is configured to provide an illumination beam. A light guide plate has a first surface, a second surface opposite to the first surface, and an incident surface connecting the first surface and the second surface. The illumination beam enters the light guide plate through the incident surface. A reflective element is connected to the light guide plate and has a plurality of first reflective surfaces inclined with respect to the second surface. A reflective display unit is capable of modulating a polarization state of the illumination beam to form a modulated beam. The second surface is disposed between the reflective display unit and the first surface. The first surface is disposed between the second surface and a reflective polarizer, and the reflective polarizer filters the modulated beam into an image beam.
