A projection system includes a light source producing illumination light, an imager disposed to receive the illumination light, and a projection lens disposed to receive the illumination light from the imager. The imager includes an intrinsic polarizer. The intrinsic polarizer can be an intrinsic polarizer stack including a U.V. curable adhesive.

Projection system including intrinsic polarizer

A projection system including an intrinsic polarizer is disclosed. The projection system includes a light source producing illumination light, an imager disposed to receive the illumination light, and a projection lens disposed to receive the illumination light from the imager. The imager includes an intrinsic polarizer. An intrinsic polarizer stack including a U.V. curable adhesive is also disclosed.

A liquid crystal display structure includes a liquid crystal display cell having a front surface and a back surface. One or more intrinsic polarizers lacking protective coatings thereon, such as K-type polarizers and thin KE polarizer sheets, are disposed adjacent to the front and back surfaces of the liquid crystal display cell. Alternatively, thinly cladded or encased iodine polarizers are disposed adjacent to the front and back surfaces of the liquid crystal display cell. The liquid crystal display structure may be used in conjunction with other optical display elements to enhance the brightness and contrast of the liquid crystal display.

Polarizers for use with liquid crystal displays

A high durability circular polarizer includes an unprotected K-type polarizer, such as a KE polarizer sheet, and a quarter-wavelength retarder. An optical system using the circular polarizer further includes an emissive display module such as an organic light emitting diode or a plasma display device.

A protectively reflected binary image is provided comprising a thermally imaged transparency on which is superposed a thin reflective protective overcoat, the imaged transparency comprising a binary image supported on a transparent substrate. The reflective protective overcoat is interfacially bonded to the thermally imaged transparency preferably such that the binary image is interposed between the transparent substrate and the reflective protective overcoat. A method for transferring a reflective protective overcoat onto an imaged transparency is also provided, whereby an image surface of the imaged transparency is protected and made viewable as a reflected image, the method utilizing a laminar transfer sheet comprising a carrier web and a reflective protective overcoat, the laminar transfer sheet being laminated onto the image surface with the carrier web subsequently removed to thereby release the reflective protective overcoat, the overcoat remaining bonded to the image surface.
