20110171400 | OPTICAL BONDING WITH SILICON-CONTAINING PHOTOPOLYMERIZABLE COMPOSITION - 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. | 07-14-2011 |
20120268967 | LIGHT GUIDES - 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. | 10-25-2012 |

20140340927 | LIGHTGUIDE AS LUMINAIRE - 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. | 11-20-2014 |
