ABSTRACT:
The present invention provides a light polarizing device comprising a light separating module and a retarder for converting an input trichrome unpolarized light having red, green and blue lights. The light separating module comprises a polarization beam splitter film and a dichroic film for separating the input trichrome unpolarized light into two trichrome polarized lights with different polarizations, each color light within the first trichrome polarized light and the second trichrome polarized light having a unique polarization. The retarder retards the first trichrome polarized light or the second trichrome polarized light so as to generate an output of trichrome polarized light with different polarizations. Furthermore, the light separating module is a stackable module that can be vertically stacked with other modules to form a light separating panel.
