Problems solved by technology

Lenses are often small from a performance standpoint (to keep costs down) and relatively poorly transparent due to conductive layers, spacers, and reflections from the lens surface
Lenses are limited to planar forms as there is no successful process for thermoformed LC lenses

Embodiment Construction

[0029] One technique to overcome the disadvantages of shuttered glasses systems involves breaking down the shutters so that the modulator part resides at the image generation unit and the passive decoding polarized glasses reside at the viewer. This arrangement is described in commonly owned US Patent No. 6,975,345, which is incorporated herein by reference. Passive glasses can basically eliminate the above disadvantages. Light-weight, low-cost, and comfortable thermoformable polarized glasses can now be worn by spectators while the polarization modulation unit is attached to the surface of the AMLCD. The challenge involved with this technique is that the area of ​​the polarization modulator is essentially the same as that of the image generating unit. Fabricating a large glass LC polarization switch, laminating an additional polarization functional layer to the switch and attaching it to the surface of the LCD has the potential to add significant cost to the display bill of ...

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.

Description

[0001] Cross-references to related applications: This application claims U.S. Provisional Patent Application Serial No. 61 / 306,897, filed February 22, 2010, and entitled "Plastic liquid crystal polarization switch for direct view stereoscopic display" Priority, the US Provisional Patent Application is hereby incorporated by reference in its entirety. technical field [0002] The present disclosure relates generally to flat panel displays, and, more particularly, the present disclosure relates to low cost, robust, large area modulator configurations compatible with flat panel display systems. Such modulators are particularly useful for sequential stereoscopic displays using passive glasses. Background technique [0003] Active Matrix Liquid Crystal Displays (AMLCDs) are the most ubiquitous information display technology from handheld devices to large screen televisions, yet no method is currently available to enable a high quality stereoscopic 3D experience. Methods that ca...
