An organic light emitting diode (OLED) display includes a pixelated OLED display panel and a color-correction component disposed on the pixelated OLED display panel. The pixelated OLED display panel has a ratio of blue-to-red color mixing weights at 30 degrees of β, and a ratio of blue-to-red color mixing weights at 45 degrees of β, where β≥β≥1.05 and 1.5≥β≥1.1. The color-correction component is configured such that a ratio of blue-to-red color mixing weights at 45 degrees of the display is βand a ratio of blue-to-red color mixing weights at 30 degrees of the display is β, where β−0.1≥β≥2.1−βand β−0.05≥β≥2.05−β. Methods of making OLED displays are described.

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.

An organic light emitting diode (OLED) display is described, and includes a pixelated OLED display panel including N a plurality of pixels, each pixel including a plurality of subpixels, and each subpixel including a plurality of OLED layers. A hybrid color correction component is disposed on the pixelated OLED display panel, and the hybrid color-correction component includes a nanostructured interface and an angular transformation layer, the angular transformation layer is disposed between the nanostructured interface and the pixelated OLED display panel.

Organic light emitting diode display with color-correction component

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 WPCSand a white-point axial efficiency of WPAE. 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 WPCSand WPCSand respective white-point axial efficiencies of WPAE and WPAE. WPCSand WPAEdefines a performance point of the display panel to the right of the performance curve and WPCSand 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.
