Stereoscopic display device, system and method

A stereoscopic display system, comprising:

• a stereoscopic display device including
• an inner polarizer having a plurality of alternately arranged first and second polarization regions, said first polarization regions having a polarization angle of α+90 degrees, said second polarization regions having a polarization angle of α degrees,
• an outer polarizer having a plurality of alternately arranged third polarization regions and fourth polarization regions, said third polarization regions corresponding in position to said first polarization regions of said inner polarizer and having a polarization angle of α degrees, said fourth polarization regions corresponding in position to said second polarization regions of said inner polarizer and having a polarization angle of α+90 degrees, and
• a display substrate panel interposed between said inner and outer polarizers, a light beam portion that has a polarization angle of α+90 degrees after passing through said first polarization regions of said inner polarizer passing through said display substrate panel and further passing through said third polarization regions of said outer polarizer as α-degree polarized light, a light beam portion that has a polarization angle of α degrees after passing through said second polarization regions of said inner polarizer passing through said display substrate panel and further passing through said fourth polarization regions of said outer polarizer as (α+90)-degree polarized light;
• and
• stereoscopic glasses including first and second lenses, said first lens permitting passage of α-degree polarized light therethrough, said second lens permitting passage of (α+90)-degree polarized light therethrough.

A stereoscopic display method, comprising:

• (a) generating a light beam;
• (b) causing a left eye image signal and a right eye image signal to be displayed on a display substrate panel having a liquid crystal layer;
• (c) causing the light beam to pass through an inner polarizer having a plurality of alternately arranged first and second polarization regions, the first polarization regions having a polarization angle of (α+90 degrees, the second polarization regions having a polarization angle of α degrees, the light beam passing through the inner polarizer being split into a plurality of (α+90)-degree polarized beam portions and a plurality of α-degree polarized beam portions in an alternating pattern;
• (d) causing the polarized beam portions to pass through the liquid crystal layer of the display substrate panel such that the (α+90)-degree polarized beam portions are rotated 90 degrees to become α-degree polarized light and that the α-degree polarized beam portions are rotated 90 degrees to become (α+90)-degree polarized light;
• and
• (e) causing the α-degree polarized light and the (α+90)-degree polarized light to pass through an outer polarizer having a plurality of alternately arranged third polarization regions and fourth polarization regions, the third polarization regions corresponding in position to the first polarization regions of the inner polarizer and having a polarization angle of α degrees, the fourth polarization regions corresponding in position to the second polarization regions and having a polarization angle of α+90 degrees.
