Abstract: Articles and laminates include a substrate with a first polyester surface and a second polyester surface, a crosslinked polyurethane-based primer coated on at least the first polyester surface, and an optically clear heat activated adhesive adjacent to the crosslinked polyurethane-based primer. The articles and laminates are prepared by applying a polyurethane-based dispersion and a crosslinker on at least one polyester surface, drying the applied coating, heating while stretching the substrate and the coating to form a crosslinked primer layer on the stretched polyester surface, and applying an optically clear heat activated adhesive onto the crosslinked primer layer.

Abstract: 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 β030, and a ratio of blue-to-red color mixing weights at 45 degrees of β045, where β045≥β030≥1.05 and 1.5≥β045≥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 β45 and a ratio of blue-to-red color mixing weights at 30 degrees of the display is β30, where β045−0.1≥β45≥2.1−β045 and β030−0.05≥β30≥2.05−β030. Methods of making OLED displays are described.

Abstract: An optical construction includes a lens film having a plurality of optically transparent first beads at least partially embedded in a first layer. A light blocking second layer is disposed on the lens film and defines a plurality of through openings therein extending at least partially between opposite major top and bottom surfaces of the second layer. The through openings are aligned to the first beads in a one-to-one correspondence.
