1. A display module comprising:
a light source configured to provide an illumination beam; a light guide plate having 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 entering the light guide plate through the incident surface; an optical structure connected to the light guide plate and configured to change a propagation direction of the illumination beam; a reflective display unit capable of modulating a polarization state of the illumination beam to form a modulated beam, the second surface being disposed between the reflective display unit and the first surface; and a reflective polarizer, the first surface being disposed between the second surface and the reflective polarizer, the reflective polarizer filtering the modulated beam into an image beam. |
