Patent number: 10288254Abstract: This application describes a front-lit reflective display assembly including a reflective display and an illumination article for front-lighting the display when the article is optically coupled to a light source. The illumination article includes a variable index light extraction layer optically coupled to a lightguide. The variable index light extraction layer has first and second regions, the first region comprising nanovoided polymeric material, the second region comprising the nanovoided polymeric material and an additional material, the first and second regions being disposed such that for light being transported at a supercritical angle in the lightguide, the variable index light extraction layer selectively extracts the light in a predetermined way based on the geometric arrangement of the first and second regions. Front-lit reflective display devices including the front-lit reflective display assembly optically coupled to a light source are also described.Type: GrantFiled: February 23, 2012Date of Patent: May 14, 2019Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Kevin R. Schaffer, David Scott Thompson, Zhaohui Yang, Encai Hao, Audrey A. Sherman, Michael A. Meis, William J. Bryan, John A. Wheatley, Joseph W. Woody, Steven D. Solomonson, Matthew S. Stay, Mikhail L.

Patent number: 10036517Abstract: A lightguide functioning as a luminaire. The luminaire includes at least one solid state light source, such as an LED, and a lightguide configured to receive light from the solid state light source. Light from the light source is coupled into the lightguide and transported within it by total internal reflection until the light exits the lightguide. A shape of the lightguide causes and directs extraction of the light, and can also be used to create a particular pattern of the extracted light. Such shapes include linear wedges and twisted wedges. Optical films can be included on the light input and output surfaces of the lightguide.Type: GrantFiled: May 16, 2013Date of Patent: July 31, 2018Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Raymond P. Johnston, Robert L. Brott, Patrick R. Fleming, Karl J. L. Geisler, Kayla A. Hagens, Steven G. Lucht, Charles N. Devore, Joseph W. Woody, V, David Scott Thompson

Patent number: 9879157Abstract: Transfer tapes include an optically transparent adhesive layer with a first major surface and a second major surface, with at least one of the major surfaces including a microstructured pattern that is a permanent feature of the adhesive surface. The microstructured surface alters the direction of light. The optically transparent composition may include a low Tg polymeric component with a Tg of less than 20° C., and an acid or base functionality, and a high Tg polymeric component with a Tg of greater than 20° C., and an acid or base functionality, such that the functionality of the low Tg polymeric component and the functionality of the high Tg polymeric component form an acid-base interaction when mixed. The transfer tapes can be adhered to substrates to provide a microstructured surface to the substrate surface.Type: GrantFiled: September 26, 2012Date of Patent: January 30, 2018Assignee: 3M Innovative Properties CompanyInventors: Audrey A. Sherman, Kevin R. Schaffer, Robert L. Brott, Rolf W. Biernath, Joseph W. Woody, V, John A. Wheatley

Patent number: 9301397Abstract: Metalized web substrate is wet etched in a reaction vessel by contacting with oxidizing and metal complexing agent to remove metal from unpatterned region. Following etching, substrate is rinsed, and rinse is at least partly recycled. Concentrations of oxidizing and metal complexing agents in the etchant bath are maintained by delivering replenishment feeds of each. Concentration of metal in the etchant bath is maintained by discharging some of the etchant bath. Replenishment rates of oxidizing and metal complexing agents and etchant removal rate are determined based at least in part on rate that metal etched from the substrate enters the etchant bath.Type: GrantFiled: September 19, 2012Date of Patent: March 29, 2016Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Jeffrey H.
