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.

Abstract: The projection device includes a light source, a liquid crystal on silicon (LCoS) panel, and a circuit. The circuit is configured to obtain a target image including a target pattern, and generate two content images. Each content image includes a duplicated pattern of the target pattern, and the duplicated patterns are off-axis shifted to the same coordinate when performing a computer-generated hologram (CGH) algorithm, so as to generate a phase image. The LCoS panel is driven according to the phase image to display a reconstructive image at a reconstructive distance.
