METHODE OF THE 3D DISPLAY FROM ONE LCD PROJECTOR WITH LCD PANEL HAVE BEEN CONVERSION TO CIRCLE POLARIZED LIGHT FROM LINEAR POLARIZED LIGHT

摘要

PURPOSE: A liquid crystal display projector for a stereo-image by using a circular polarizing filter is provided to realize a stereo-image with only one projector by using a polarizing filter. CONSTITUTION: In a liquid crystal display projector for a stereo-image, some photoactive material is coated on a polyester transparent film so that a polarized light is delayed by 90 degrees and some photoactive material is coated on a first polyester transparent film so that the light from the first polyester transparent film is rotated to left and right and is restored to an original image.
