Abstract: Lightguides are disclosed. More particularly, lightguides that include a lightguiding layer and a light extracting layer having a structured surface are disclosed. The light guiding layer is optically coupled to a first set of structures of the structured surface at given locations, and is not optically coupled to a second set of structures at given locations, thereby producing total internal reflection at the second locations. The selective optical coupling may be achieved by a number of different contemplated means as discussed herein. The lightguides allow for distribution of light along with redirection towards an image viewer without a number of commonly required optical elements in backlights.

Abstract: An optical assembly including a display panel is disclosed herein. The display panel is optically bonded, using a photopolymerized layer, to a substantially transparent substrate. The photopolymerized layer is formed from a photopolymerizable layer having a silicon-containing resin comprising silicon-bonded hydrogen and aliphatic unsaturation and a platinum photocatalyst present in an amount of from about 0.5 to about 30 parts of platinum per one million parts of the photopolymerizable layer. Methods of making the optical assembly are also disclosed herein. The optical assembly may be used in an optical device such as a handheld device, a television, a computer monitor, a laptop display, or a digital sign.

The photopolymerizable composition may be free of catalyst inhibitor. Also disclosed herein are methods of making the light emitting device.

Abstract: Direct-lit backlights and associated methods and components are disclosed in which a transflector that partially transmits and partially reflects incident light is shaped to form at least one concave structure facing a back reflector of the backlight. This provides at least one recycling cavity therebetween, the at least one recycling cavity substantially filling the output area of the backlight. At least one light source is disposed behind the output area to inject light into each cavity, and can be positioned in the recycling cavity or behind an aperture in the back reflector. The cavities are preferably shallow and wide, having a width-to-depth ratio of at least 5 or 10, and can provide uniform brightness and color at the output area with sparsely distributed light sources and in a thin profile backlight.
