We developed a 5.5 inch, VGA (640×480×RGB), stereoscopic 3D display using a precisely patterned wire-grid polarizer (WGP) with rows of alternating polarization angle. Such a wire-grid polarizer is invisible without the polarizer and thus a 2D/3D convertible display can be formed. The proposed structure is free of any limitations on both viewing angle and viewing distance inherent in the conventional stereoscopic displays, whereby enabling several persons to view stereoscopic image simultaneously. Because the proposed structure does not use conventional polarization film of TFT-LCD panel, it can be manufactured with low-cost.

Moxtek introduces a flat ProFlux™ wire-grid polarizing beam splitter for use in projection systems where preservation of image quality is required upon reflection at the PBS. This paper discusses advantages obtainable when using the ProFlux™ flat PBS in projection display architectures, and reasons for these advantages. Specifically, these advantages include high system contrast, simplified designs with various LCOS panels, and inherent high durability.

Moxtek has developed a new polarizer technology for the visible spectrum based on the technology of nanometer-scale wire-grids. They have named their technology ProFlux Polarizers. (more…)

Each year the Society awards the Display of the Year Award to several leading edge display devices or technologies that provide innovative solutions to an information display need. The following paper provides a summary of a 2001 Display of the Year award recipient. The new polarization technology described here enables new solutions to difficult and fundamental problems in the display industry. It is applicable and valuable in all types of Liquid-Crystal (LC) displays or other applications of polarization in information display technology.

We studied the optical performance of reflective wire-grid polarizer designed for visible light. The polarizer reflects Epolarization and transmits H-polarization with low losses. When used in a twisted nematic (TN) device as a back polarizer it enhances the brightness and provides high contrast ratio at wide viewing angles. By placing the wire-grid polarizer within the cell, viewing parallax is eliminated. The polarizer can also be used as the rear electrode.

The ProFlux BIR Series Infrared polarizer, designed using Moxtek Nanowire Technology, provides unparalleled broadband infrared performance. Moxtek’s high volume production capacity ensures availability and supports high volume applications. (more…)

Wire-grid polarizers are now available for broadband visible applications. This type of polarizer is very attractive for projection display applications because of its high efficiency, high contrast, and extreme temperature and flux tolerance.
