Abstract: A multi-primary-color light splitting and combining system, includes a dichroic device, receiving an incident light beam and splitting into a first light beam having a first wavelength range and a second light beam having a second wavelength range. The first wavelength range in wavelength value is larger than the second wavelength range. A first polarized beam splitter receives the first light beam and splits out a first polarization beam having a first predetermined polarization state. A second polarized beam splitter receives the second light beam and splits out a second polarization beam having a second predetermined polarization state. A first and a second reflective displaying panels respectively receive the first and second polarization light beams, and reflect first and second sets of image information with respect to multiple primary colors. A polarized beam splitter combines first and second sets of image information to form an image light beam.
