    摘要: In an example embodiment, a wire grid polarizer includes a plurality of parallel conductors having a pitch (P), a width (W), and a height (H). In example embodiments, a fill-factor (W/P) is greater than approximately 0.18 and less than approximately 0.25. In another example embodiment, a display system includes a light source and a light-valve. The display system also includes a wire grid polarizer that includes a plurality of parallel conductors having a pitch (P), a width (W), and a height (H). In example embodiments, a fill-factor (W/P) is greater than approximately 0.18 and less than approximately 0.25.

    摘要: Disclosed is an optical device comprising a polarizer package comprising an integrated combination of an absorbing layer and a compensator. Two of the identical polarizer packages can be crossed and used in a transmissive optical device. This polarizer package can also be used in combination with a reflective plate and a quarter wave plate in a reflective optical device. Such polarizer packages exhibit an improved viewing angle characteristic across all wavelengths of interest, has a large tolerance for compensators to be aligned relative to their preferred directions, and can be used within an LCD or emissive display system.

    摘要: A display apparatus (30) has an LC device (14) exhibiting its maximum contrast with incident light at an oblique angle φ from normal, wherein oblique angle φ is greater than about +/−10 degrees from normal. A backlight unit (32) provides substantially collimated illumination with a central ray at an incident angle θ2 with respect to the LC device (14), wherein incident angle θ2 within about +/−5 degrees of oblique angle φ. The full-width half-maximum intensity of the illumination is within about +/−10 degrees of the central ray at incident angle θ2.
