Full resolution stereoscopic television using flicker-free active beam displacement glasses

We have devised full resolution stereoscopic television system incorporating both patterned retarder and active glasses. Selective vision of the left image by the left eye and the right image by the right eye is achieved by conventional combination of patterned retarder and left and right polarized filters. Full resolution is provided by active components of glasses acting as a switchable beam displacer. Pairs of line-interleaved images are displayed on LCD screen sequentially at a frame-rate 120 Hz. Viewer can see full resolution stereoscopic images as if they are displayed in interlaced manner by active glasses. Active glasses are flicker free. Patterned retarder defines crosstalk level in a range below 1%.
