Abstract： |
A display comprises optical source component, beam splitting/combining system and projection lens as beam splitting/combining system consists of polarizer, two wave plates with wide waveband, polarization spetroscope, dichroic mirror, analyser and three reflecting liquid crystalls which can modulate separately three colour lights of red, blue and green. The polarization spectroscope is a prism built by two triangu9lar prisms with wide wavelength polarization spectrofilm plated on public glued surface and dechroic mirror is planar dechroic mirror plated with double colour spectrofilm. |
