US 2011/0211135 A1 · Bendable liquid crystal polarization switch for direct view stereoscopic display

Abstract

A system for stereoscopic display and a bendable polarization switch for use with a system for stereoscopic display provide alternately polarized left and right eye images. Viewers then wear polarization analyzing eyewear to correctly see the different images. More specifically, a bendable polarization switch may be laminated to the front of a system for stereoscopic display. The bendable polarization switch may be used with a modulator configuration that is compatible with various performance requirements in a manner that is a low-cost manufacturing friendly solution. Further, the bendable polarization switch is a robust polarization switch technology that is reliable in an environment where mechanical stresses are inevitably applied during product lifetime

Dependent claims

A flat panel display assembly operable to display stereoscopic imagery, comprising:

a backlight unit operable to provide light;
an input polarizer operable to polarize the light provided by the backlight unit;
a liquid crystal modulation panel positioned to receive the light from the input polarizer and operable to modulate the light received from the input polarizer;
an output polarizer operable to block a portion of the modulated light from the liquid crystal modulation panel and to pass another portion of the modulated light from the liquid crystal;
a pressure sensitive adhesive layer disposed on a surface of the output polarizer opposite the liquid crystal modulation panel;
and
a bendable polarization switch operable to receive light from a surface of the output polarizer opposite the liquid crystal modulation panel.
