  • Patent number: 12287502
    Abstract: A light control film is described comprising a light input surface and alight output surface opposite the light input surface; alternating transmissive regions and absorptive regions disposed between the light input surface and the light output surface, wherein the absorptive regions comprise light-absorbing or light-reflecting particles and a dried aqueous dispersion of an organic polymer. The light control film can have improved on-axis transmission in combination with sufficiently high sheet resistance such that the film does not detract from the responsiveness of a touch screen of an electronic device. Also described is a coated article and method of making.

  • Publication number: 20230024412
    Abstract: The present disclosure provides a light control film and a method of manufacturing the same. The method includes providing a microstructured film. The microstructured film includes a plurality of light transmissive regions alternated with channels. The microstructure film is defined by a top surface and a pair of side surfaces of each light transmissive region and a bottom surface of each channel. The method further includes coating the pair of side surfaces of each light transmissive region and the bottom surface of each channel with a coating. The coating includes light absorbing particles that are dispersed in a liquid. The method further includes drying the coating such that the light absorbing particles are selectively deposited on the pair of sides surfaces of each light transmissive region.

  • Patent number: 11231536
    Abstract: A polarizer including an oriented polymeric first layer is described. The oriented polymeric first layer is preparable from a mixture of polyvinyl alcohol and crosslinker where the crosslinker is included in the mixture at 5 to 40 percent by weight based on the total weight of the polyvinyl alcohol and crosslinker. The oriented polymeric first layer is a substantially uniaxially drawn layer, in that for U=(1/MDDR?1)/(TDDR1/2?1), U is at least 0.85, with MDDR being a machine direction draw ratio and TDDR being a transverse direction draw ratio.

  • Patent number: 9915762
    Abstract: A sheet comprising: (1) a core member comprising one or more layers and having a first major surface and (2) a slip control layer disposed on at least a portion of the first major surface, wherein the slip control layer comprises: (i) a footing layer disposed on at least a portion of the first major surface of the core member, (ii) a binder layer disposed on the footing layer, and (iii) an array of particles disposed in the binder layer and footing layer and protruding therefrom, wherein the average diameter of the particles is greater than the combined thickness of the foot layer and binder layer.

  • Patent number: 9895837
    Abstract: A textured film, a process for manufacture of the textured film, and a light management stack, a backlight, and a display using the textured film are described. The textured film and process for manufacture thereof, include processes in which the surface texture of the optical film is controlled by incorporation of a patterned coating. The surface texture of a polymeric film, such as a polymeric optical film, is controlled by incorporation of the coating, that can fracture or deform upon stretching the film.

  • Patent number: 9260612
    Abstract: An antistatic article having an antistatic layer disposed on a substrate is disclosed herein. The antistatic layer is formed from a cationic copolymer, a non-cationic (meth)acrylic polymer, and a crosslinking agent. The cationic copolymer consists essentially of a cationic monomer, a hydrophobic monomer, a crosslinkable monomer, and an optional nitrogen-containing monomer. The substrate may comprise an optical film such as a multilayer optical film. Methods for making the antistatic article and display devices containing the antistatic article are also disclosed.
