  • Publication number: 20220271261
    Abstract: The present disclosure provides an article including a layer having a nanostructured first surface including nanofeatures and an opposing second surface, and an organic layer including a major surface attached to a portion of the nanofeatures. The nanostructured first surface includes protruding features that are formed of a single composition and/or recessed features. The nanofeatures and the major surface of the second layer together define at least one void. The present disclosure also provides a method of making the article including contacting nanofeatures of a layer having a nanostructured surface with a major surface of an organic layer and reacting at least one material to secure the two layers together. In addition, the present disclosure provides an optical information display and an OLED device including the article. The nanostructured surface of the article is protected from damage and contamination by the organic layer.

  • Publication number: 20210098546
    Abstract: 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.
