摘要： Multilayer reflective polarizers are described. More particularly, multilayer reflective polarizers having a higher block light transmission at longer wavelengths than shorter wavelengths while having a high pass light transmission are described. The described multilayer reflective polarizers may be combined with absorbing polarizers or used in display devices.

摘要： An optical system for displaying an image to a viewer includes a pixelated display including a plurality of pixels emitting unpolarized image light; a partial reflector having an average optical reflectance of at least 30% in a predetermined wavelength range; a first retarder layer disposed between the pixelated display and the partial reflector; a second retarder layer disposed between the first retarder layer and the partial reflector; and a reflective polarizer disposed between the first and second retarder layers. The reflective polarizer is adapted to increase a brightness of a pixelated image emitted by the pixelated display and displayed to the viewer by recycling at least a portion of unpolarized image light emitted by the pixels; and receive an image ray reflected by the partial reflector and reflect the received image ray toward the viewer.

摘要： An optical stack includes a reflective polarizer including a plurality of interference layers and an absorbing polarizer disposed on the reflective polarizer. The plurality of interference layers transmits at least about 85% of an incident light having a first polarization state, reflects at least about 80% of the incident light having a second polarization state, and transmits less than about 0.1% of the incident light having the second polarization state. The absorbing polarizer has a first transmittance for the first polarization state and a second transmittance for the second polarization state. An average of the first and second transmittances is greater than about 0.46. The second transmittance has a first standard deviation. The optical stack has a transmittance for the second polarization state having a second standard deviation which is less than the first standard deviation by at least about 10%. A display includes the optical stack.
