<P>PROBLEM TO BE SOLVED: To provide a direct-view stereoscopic display requiring polarizing spectacles, which is free from vertical resolution degradation in stereoscopic viewing in comparison with non-stereoscopic viewing. <P>SOLUTION: Two kinds of an R first picture composed by taking odd lines out of scanning lines of a left picture and a right picture being a stereoscopic pair, as a right picture and taking even lines as a left picture and an L first picture composed by taking odd lines as a left picture and taking even lines as a right picture are created and are alternately displayed on a liquid crystal display having an Xpol mounted thereon and driven at a double speed. A polarization axis variable liquid crystal plate which is transparent and changes only a polarization direction by 90° is placed over the liquid crystal having the Xpol mounted thereon, and the polarization direction is changed synchronously with rewriting positions of the L first picture and the R first picture. A backlight is provided with an extinction region and is extinguished in the picture rewriting positions. Polarizing spectacles are used, and a 1/4-wave plate is mounted in the front of the polarization axis variable liquid crystal plate if circularly polarizing spectacles are used. Thus, stereoscopic viewing with high resolution and simultaneous display of left and right pictures is realized. <P>COPYRIGHT: (C)2012,JPO&INPIT |
