Abstract:
A flat panel three-dimensional display unit for displaying thereon stereo images from left and right input images, the stereo images being viewable with a pair of standard polarized glasses, said display unit comprising: a first liquid crystal panel; a second liquid crystal panel, said panels each having a plurality of identical pixels, each pixel imparting a first-polarization component and a second-polarization component to a beam passing therethrough; an illuminator for emitting and transmitting a beam of light to be incident on said panels; a first polarizer of first polarization, said first polarizer being sandwiched between said illuminator and said first liquid crystal panel; a second polarizer of second polarization, said second polarizer being positioned between said first and second liquid crystal panels, said first and second polarizers being orthogonal to each other; and a computer processor capable of processing left input images and right input images to produce therefrom a first driving video signal representing the composite sum of the intensities of the left and right input images and a second driving video signal representing the intensity of the left input image divided by said composite sum; and a plurality of channels for coupling said driving video signals from said processor to said liquid crystal panels, said driving video signals operating on said beam of light passing through said liquid crystal panels such that when said beam of light exits said second liquid crystal panel, said first-polarization component imparted by each pixel of said second panel corresponds to the left image and said second-polarization component imparted by each pixel of said second panel corresponds to the right image, thereby exhibiting stereo images that are viewable via a pair of standard polarized glasses.
