Abstract
Systems and apparatus are provided for viewing a display element configured to reflect light rays incident on a surface of the display element. A microdisplay system comprises a display element having a reflective surface and a polarizer configured to absorb light rays of a first polarization and transmit light rays of a second polarization orthogonal to the first polarization. A light deflection element is disposed between the reflective surface of the display element and the polarizer, and a light source is disposed adjacent to the light deflection element. The light source is configured to produce light rays, wherein the light deflection element deflects light rays from the light source having the first polarization toward the reflective surface of display element and transmits light rays reflected from the display element having the second polarization.
