  • Publication number: 20190219743
    Abstract: 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.

    Abstract: An optical stack including a periodically varying optical film layer and a grating assembly for reducing moiré is described. The grating assembly includes first and second layers where an interface between the first and second layers define a grating having a peak to valley height and an index contrast. The index contrast multiplied by the peak to valley height may be between 150 nm and 350 nm and the grating has a pitch in the range of 2 micrometers to 50 micrometers. Each of the first and second layers may be viscoelastic or elastomeric adhesive layers, crosslinked resin layers, or soluble resin layers.

  • Patent number: 9690038
    Abstract: A backlight includes a light source and one or more light recycling films. The light source generates light that exits the light source with an angular exit distribution. The light recycling films are oriented in relation to the light source so that the prism peaks of the recycling films are oriented away from the light source. The recycling films have a range of optimal incident angles that allow light to pass through the recycling films without recycling. The components of the light source, the characteristics of the recycling films, or both, are configured to control the overlap between the exit distribution of the light source and the optimal incident angle range of the recycling films.

  • Patent number: 9684119
    Abstract: 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 moire fringes occur when the flexible unitary lightguide is used as a backlight in a pixelated display.
