    摘要: A curved reflective has at least one location having a radius of curvature in a range from about 6 mm to about 1000 mm. Each location on the reflective polarizer has a maximum reflectance greater than about 70% for a block polarization state, a maximum transmittance greater than about 70% for an orthogonal pass polarization state, and a minimum transmittance for the block polarization state. For a continuous first portion of the reflective polarizer extending between different first and second edges of the reflective polarizer and defining disjoint second and third portions of the reflective polarizer, the minimum transmittance of the reflective polarizer for the block polarization state is higher at each location in at least 70% of the first portion than at each location in at least 70% of the second portion and at each location in at least 70% of the third portion.

    摘要: A display system including an imager for forming an image, and a projection lens system for projecting the image formed by the imager is described. For each pixel in the plurality of pixels, the imager is configured to emit a cone of light having a central ray having a direction that varies with location of the pixel in the imager. The variation may increase a brightness of an image projected through the projection lens system by at least 30 percent. The display system may include a light guide having a light insertion portion adapted to receive light; a light transport portion disposed to receive light from the light insertion portion; and a light extraction portion disposed to receive light from the light transport portion.

    摘要: An optical system including a first optical element having a curved first major surface and an optical stack bonded and conforming to the curved first major surface of the first optical element is described. The optical stack includes a reflective polarizer substantially transmitting light having a first polarization state and substantially reflecting light having an orthogonal second polarization state and a non-adhesive flexible optical layer bonded to the reflective polarizer and comprising substantially parallel opposing first and second major surfaces. At least one location on the non-adhesive flexible optical layer has an optical retardance of less than about 100 nm or greater than about 200 nm at a wavelength of about 550 nm.

    摘要: Shaped optical films and methods of shaping optical films are described. The method includes securing at least portions of a perimeter of the optical film in a first plane so that the secured portions do not move relative to one another; and stretching the optical film by displacing a portion of the optical film along at least a first direction perpendicular to the first plane such that one of a radial and circumferential stretching of the optical film is substantially constant from a center to the perimeter of the optical film, and the other one of the radial and circumferential stretching of the optical film substantially changes from the center to the perimeter of the optical film. The optical film is a reflective polarizer including a plurality of alternating polymeric layers.

    摘要: An optical element includes an optical surface configured to receive light at a predetermined wavelength in a range from about 400 nm to about 1000 nm. The optical surface is defined by a vertical axis and a horizontal axis defining four Cartesian quadrants sequentially numbered in a counter-clockwise direction. A first longitudinal section of the optical surface is centered on the vertical axis and a second longitudinal section of the optical surface is centered on the horizontal axis. The first and second longitudinal section each extend across opposite edges of the optical surface and have a same substantially uniform retardance for substantially normally incident light. The optical element includes four discrete retarder sections. Each retarder section is disposed on a respective Cartesian quadrant of the optical surface and has a retardance difference from the substantially uniform retardance of the optical surface that is greater than zero.
