52.4: New, High Performance, Durable Polarizers for Projection Displays

Abstract

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. However, using wire-grid polarizers as drop-in replacements in existing architectures, significantly limits the possible applications of this new polarizer type. As with conventional polarizers, wire-grid polarizers come in a sheet format, but they reflect one polarization rather than absorb it. Therefore, care must be taken in the system design to control this reflected light. Other significant design issues will also be highlighted in this paper. Applied Digital Optics, Inc. and MOXTEK will discuss design issues concerning the use of ProFlux™ wire-grid polarizers in the illumination stages for projection, as well as other suitable applications. Conceptual designs will be presented.

25.3: Auto‐Stereoscopic TFT‐LCD with LC Parallax Barrier on Wire Grid Polarizer

“…A WGP has higher contrast and is less expensive than a conventional MacNeille polarizing beam splitter (PBS) based on thin layers on prismatic glass. Therefore, a WGP is a good alternative PBS in many applications such as projection systems in liquid-crystal on silicon (LCoS) displays [7] and 3D displays [8]. Figure 2 shows the principle of the conventional (a) and proposed (b) structures for auto-stereoscopic 3D display with LC parallax barrier.…”

Therefore, a WGP is a good alternative PBS in many applications such as projection systems in liquid-crystal on silicon (LCoS) displays [2] and in 3D displays [3].…”

Wire-grid diffraction gratings used as polarizing beam splitter for visible light and applied in liquid crystal on silicon

“…A WGP has higher contrast and is less expensive than a conventional MacNeille polarizing beam splitter (PBS) based on thin layers on prismatic glass. Therefore, a WGP is a good alternative PBS in many applications such as projection systems in liquid crystal on silicon (LCoS) displays [1]. When the wave vector of the incident plane wave is not in the plane perpendicular to the grooves, i.e.…”
