摘要： Flexible unitary lightguide and a method of making the same are disclosed. The lightguide includes a structured input side that includes a first pattern having smaller features superimposed on a second pattern having larger features. The lightguide further includes a structured top surface that includes a first region and a different second region. The first region includes a plurality of discrete light extractors for extracting light that propagates within the flexible unitary lightguide by total internal reflection. The second region includes a taper portion for directing light from the structured input side to the first region. The light extractors form a periodic array that has a first period along the length of the flexible unitary lightguide. The first period is such that substantially no visible moir fringes occur when the flexible unitary lightguide is used as a backlight in a pixelated display.

摘要： Optical diffusing films are made by microreplication from a structured surface tool. The tool is made using a 2-part electroplating process, wherein a first electroplating procedure forms a first metal layer with a first major surface, and a second electroplating procedure forms a second metal layer on the first metal layer, the second metal layer having a second major surface with a smaller average roughness than that of the first major surface. The second major surface can function as the structured surface of the tool. A replica of this surface can then be made in a major surface of an optical film to provide light diffusing properties. The structured surface and/or its constituent structures can be characterized in terms of various parameters such as optical haze, optical clarity, Fourier power spectra of the topography along orthogonal in-plane directions, ridge length per unit area, equivalent circular diameter (ECD), and/or aspect ratio.

摘要： Generally, the present disclosure relates to light control films. The present disclosure also relates to assemblies incorporating light control films. In some embodiments, the light control films of the present disclosure regulate transmission of one or more of visible light, ultraviolet light, and infrared light that reaches a substrate after exiting the light control film. The light control film comprises waveguiding channels (130) which collect light incident under larger incidence angles towards the surface opposite the incidence surface. The channels are surrounded by a material (140) having a lower refractive index than the one the channel material and can comprise an absorbing pigment.
