    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 sheeting includes a layer of a shape-memory polymer material having a surface of microlenses, wherein each of the microlenses is associated with one of a plurality of images within the sheeting. The layer of the shape-memory polymer material is responsive to an external stimulus; e.g., temperature, solvent, or moisture; by transitioning from a first state in which an optical property of the microlenses has a first value to a second state in which the optical property of the microlenses has a second value. The microlenses have refractive surfaces that transmit light to positions within the sheeting to produce a composite image from the images formed within the sheeting when the layer of the shape-memory polymer material is in one of the first state and the second state. At least one of the images is a partially complete image, and each of the images is associated with a different one of the microlenses.
