发明名称 Display module and light guide device
摘要 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.

主权项 1. A display module comprising: at least one light source configured to provide at least one illumination beam; a light guide plate having a first surface, a second surface opposite to the first surface, and at least one incident surface connecting the first surface and the second surface, the illumination beam entering the light guide plate through the incident surface; a reflective element connected to the light guide plate and configured to change a propagation direction of at least one part of the illumination beam, the reflective element having a plurality of first reflective surfaces inclined with respect to the second surface, wherein the reflective element is a polarizing beam splitter (PBS) film and comprises a plurality of first inclined portions configured to respectively form the first reflective surfaces, and the first inclined portions reflect at least one part of the illumination beam having a first polarization direction from the incident surface; 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.
