摘要： A structured film for forming a pattern on a substrate includes a polymeric support layer, an adhesive layer, an etch resist layer disposed between the polymeric support layer and the adhesive layer, a structured resin layer disposed between the polymeric support layer and the etch resist layer, and one or more unstructured layers disposed between the etch resist layer and the adhesive layer. The structured resin layer has a structured major surface including a plurality of engineered structures. The etch resist layer at least partially fills spaces between adjacent engineered structures to substantially planarize the structured major surface. Methods of using the structured film to form a pattern on a substrate are described.

摘要： A nanostructured article having a first layer with a nanostructured surface is described. The nanostructured surface includes a plurality of pillars extending from a base surface of the first layer. The pillars have an average height greater than an average lateral dimension of the pillars. An average center-to-center spacing between pillars is no more than 2000 nm. The average lateral dimension is no less than 50 nm. Each pillar in the plurality of pillars has at least a lower portion and an upper portion where the lower portion is between the upper portion and the base surface, and the upper and lower portions have differing compositions. The nanostructured article includes a second layer disposed over the plurality of pillars and extending continuously to the base surface.

摘要： Organic light emitting diode (OLED) displays having an emissive OLED layer and a nanostructured interface configured to reduce variability of color with view angle are described. An optical stack having first and second layers with differing refractive indices includes the nanostructured interface between the first and second layers. The second layer is disposed between the first layer and the emissive OLED layer. The nanostructured interface has a substantially azimuthally symmetric power spectral density (PSD) and a wavenumber-PSD product has a maximum for a wavenumber larger than 6 radians/micrometer times the refractive index of the second layer. For all wavenumbers lower than 6 radians/micrometer times the second refractive index, the wavenumber-PSD product is no more than 0.3 times the maximum.

摘要： 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.

摘要： An optical article, such as a backlight for electronic display devices, is disclosed. The optical article includes a lightguide, a viscoelastic layer disposed on the light guide and a nanovoided polymeric layer disposed on the viscoelastic layer. The nanovoided polymeric layer comprises a plurality of interconnected nanovoids and at least some of the interconnected nanovoids are connected to one another by hollow passages. The lightguide may be optically coupled to a light source, and the viscoelastic layer and the nanovoided polymeric layer may be used in conjunction with the lightguide to manage light emitted by the light source. The viscoelastic layer may be a pressure sensitive adhesive.

摘要： A solid state light having a shell forming an interior volume and with surface texture for redirecting light. A light section is coupled to the shell, and a light source board in the light section includes at least one solid state light source such as an LED. The shell, light section, and light source board have apertures for providing an air cooling channel through the light. The solid state light source transmits light into the interior volume, and the light exits from the shell and is redirected by the surface texture, providing for various light distribution curves of the light.

摘要： 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.
