    摘要: Disclosed herein is an optical article having a top layer with a structured surface that collimates light, a core layer secured to the top layer opposite the structured surface, and a bottom layer secured to the core layer opposite the top layer. Either the top layer or the core layer includes a first extrudable polymer having a flexural modulus of greater than 2.5 GPa, and the other layer includes a second extrudable polymer having a flexural modulus of 2.5 GPa or less, an impact strength of greater than about 40 J/m, and tensile elongation at break of greater than about 5%. The bottom layer includes a third extrudable polymer. The bottom layer of the optical article may be structured to diffuse light. One or two optical articles may be secured to an optical film such as a polarizer film. Methods and display devices are also disclosed herein.

    摘要: A multilayered polymer film is formed with a stack of one or more first optical layers, one or more second optical layers, and one or more non-optical layers. These optical and non-optical layers are typically made using polymer materials, such as polyesters. In one embodiment, the non-optical layers are made from a polyester having a composition which corresponds to the average molar composition of the combination of all of the first and second optical layers. Using this formulation, scrap material from the manufacture of multilayered polymer films may be used to generate the non-optical layers in subsequent films. Alternatively, the non-optical layers of a multilayered polymer film are made using scrap material from prior-manufactured multilayered polymer films with the optional addition of other polymer material which may be either new or recycled.
