Abstract: Pre-aligned optical layers (22-30) are stacked and arranged such that an adhesive layer (32) , which is stacked onto the optical layers, contacts at least the uppermost layer (30) and lowermost layer (22). The resulting subassemblies (36, 38) can be assembled into an optical display (10a) without individual handling of the layers, which reduces installation time and manufacturing costs.

Abstract: The present disclosure is directed to backlighting systems, which include first and second lightguides, at least one light source optically connected to an edge of the first lightguide and at least one light source optically connected to an edge of the second lightguide for supplying light into their respective interiors. In the appropriate exemplary embodiments, the backlighting systems of the present disclosure include an extractor disposed at a surface of the second lightguide for diffuse extraction of light from the interior of the second lightguide. In such exemplary embodiments, at least a portion of the light supplied into the interior of the second lightguide and then diffusely extracted therefrom enters the interior of the first lightguide through a substantially optically clear surface. In some exemplary embodiments, the backlighting systems of the present disclosure include recycling enhancement structures, which may be attached to the first lightguide.

Abstract: A film that includes a first reflective polarizer (104) substantially reflecting light having a first polarization state and substantially transmitting light having a second polarization state, a polarization rotating layer (106) or depolarizing layer (112) or both positioned to receive light passing through the first reflective polarizer (104), and a second reflective polarizer (108) positioned to receive light passing through the polarization rotating layer (106) or depolarizing layer (112), the second reflective polarizer (108) substantially reflecting light having a third polarization state back through the polarization rotating layer (106) or depolarizing layer (112) and substantially transmitting light having a fourth polarization state. Articles containing the film can be formed.
