Abstract:
1. A display system, comprising: an image device used for producing a polarized image light; an image reflecting element comprising: a substrate; and a phase modulating element adjacent to the substrate, the phase modulating element having a reflecting surface for receiving the polarized image light, wherein the reflecting surface reflects a portion of the polarized image light to produce a first reflecting polarized image light after the polarized image light is projected to the reflecting surface, another portion of the polarized image light enters the phase modulating element and is reflected by the substrate and then is projected out of the reflecting surface for producing a second reflecting polarized image light, and the phase difference between the phase of the first reflecting polarized image light and that of the second reflecting polarized image light is substantially equal to nu, and n is a positive odd number; and a polarizing element for receiving and allowing the first reflecting polarized image light to pass therethrough, and blocking the second reflecting polarized image light.
