Abstract
An embodiment of the invention provides a display module including a plurality of light sources, a light guide plate, a reflective element, a reflective display unit, and a reflective polarizer. The light sources are configured to provide a plurality of illumination beams. The light guide plate has a first surface, a second surface, and a plurality of incident surfaces. The illumination beams enter the light guide plate through the incident surfaces. The reflective element is configured to change a propagation direction of at least one part of the illumination beams. The reflective element includes a plurality of reflective surfaces, and the reflective surfaces reflect the illumination beams having a first polarization direction. The reflective display unit is capable of modulating a polarization state of the illumination beams to form modulated beams. The reflective polarizer filters the modulated beams into an image beam.
