Publication number: 20210098546Abstract: An OLED display including a display panel and a color-correction component is described. A plurality of comparative display panels otherwise equivalent to the display panel but having one or more different optical thicknesses of OLED layers have a maximum white-point color shift from 0 to 45 degrees of WPCSC45 and a white-point axial efficiency of WPAEC. The plurality of comparative display panels defines a performance curve along a boundary of performance points. The OLED display and the display panel have respective maximum white-point color shifts from 0 to 45 degrees of WPCS45 and WPCS045 and respective white-point axial efficiencies of WPAE and WPAE0. WPCS045 and WPAE0 defines a performance point of the display panel to the right of the performance curve and WPCS45 and WPAE defines a performance point of the OLED display above or to the left of the performance curve. Methods of making the OLED display are described.Type: ApplicationFiled: April 9, 2019Publication date: April 1, 2021Inventors: Nicholas C. Erickson, David G. Freier, Robert L.

Publication number: 20210018694Abstract: An optical adaptor for inspection of a desired surface of an optical ferrule is provided. The optical ferrule is disposed in, and has a first position relative to, a housing of the optical ferrule. The optical adaptor includes a front portion including an open front end for insertion into the housing of the optical ferrule from an open mating end of the housing and for receiving at least a portion of the desired surface of the optical ferrule. The front portion includes a receiving surface for receiving at least a portion of the optical ferrule and causing the optical ferrule to change its position from the first position to a different second position.

Publication number: 20200392782Abstract: The present disclosure provides lamination transfer films and use of the lamination transfer films, particular in the fabrication of architectural glass elements, such as those used in Insulated Glass Units (IGUs). The lamination transfer films may be used to transfer functional layers and structures. The lamination transfer films may include a support film that can be removed during the transfer process, and the transferred materials are primarily inorganic. The resulting transferred structures on glass generally have high photo- and thermal-stability, and therefore can successfully be applied to the glass surfaces that are interior to the cavity within an IGU. The lamination transfer films can also be patterned such that macroscopic patterns of microoptical elements can be applied on a glass surface.Type: ApplicationFiled: August 28, 2020Publication date: December 17, 2020Inventors: Michael Benton Free, Martin B. Wolk, Olester Benson, JR., Bing Hao, Charles A. Marttila, Craig R. Schardt, Mieczyslaw H. Mazurek, Justin P. Meyer, Manoj Nirmal

Light redirecting film with multi-peak microstructured prismatic elements and methods of making them
Patent number: 10795061Abstract: Light redirecting film articles include a microstructured optical film, such as a daylight redirecting film, bonded to another film. This type of assembly may serve various purposes. For example, the assembly may protect the structured film, provide additional functionality, such as diffusion or infrared reflection, and/or facilitate attachment of the microstructured optical film to a mounting surface, such as a glazing or window pane.Type: GrantFiled: May 12, 2017Date of Patent: October 6, 2020Assignee: 3M Innovative Properties CompanyInventors: Manoj Nirmal, Scott M.

Publication number: 20200278501Abstract: An optical connector includes a housing with a bottom wall defining a window therein, and an optical ferrule disposed in the housing and comprising opposing major top and bottom surfaces. The major bottom surface of the optical ferrule faces the bottom wall of the housing. The major top surface includes a groove and a light redirecting surface configured to receive light along a first direction from an optical fiber received and secured in the groove, and redirect the received light along a different second direction. The redirected light exits the optical ferrule though the bottom surface and exits the housing through the window, such that, when the optical connector mates with a mating optical connector including a mating optical ferrule, the mating optical ferrule prevents any of the light exiting the optical ferrule from exiting the housing of the optical connector.Type: ApplicationFiled: February 20, 2020Publication date: September 3, 2020Inventors: Changbao Ma, Boon K.
