Polarized stereoscopic display device and method without loss

The present invention is a lossless polarization-type stereoisomers as a display method and to an apparatus, and more particularly, through a polarization property and a color signal processing technique effectively removed by giving the output optical loss high luminance polarization type of the new type with no polarization filter in the LCD projector itself It relates to a stereoscopic projection display method and apparatus. According to a preferred embodiment the invention for three-dimensional display as a first image and a second image taken from different angles for a given subject has a first image a second image and a phase difference of 90 degrees so that the output from the first projector a first signal processing section, after the first image processed signal, for outputting a first projector; And the second image is the first image having a 90 degree phase difference corresponding to the may include a second signal processing section for outputting a first, a second projector, a second projector to be output from the processing the second video image signal.
