摘要： An illumination system includes a light guide for distributing light. Extraction structures are provided to uniformly extract light from the light guide. The structures extract more light out of the light guide when light is propagating in the light guide in a direction toward the light input area than when light is propagating in the light guide in a direction away from the light input area.

摘要： A display system has a controlled transmission mirror disposed between the light sources and the display panel. The controlled transmission mirror includes a light-diverting input coupling element facing the light sources, a light-diverting output coupling element facing the display panel and a multilayer reflector between the input and output coupling elements. The controlled transmission mirror laterally spreads the light, making the illumination of the panel more uniform. The controlled transmission mirror may include a transparent substrate between the input and output coupling elements for additional light spreading. The light sources may be positioned within the controlled transmission mirror, rather than behind it. The output coupling element can be insensitive to polarization, so the light passing out of the controlled transmission mirror is unpolarized, or the output coupling element can be polarization sensitive so that the output light is polarized.
摘要翻译：显示系统具有设置在光源和显示面板之间的受控的透射镜。受控透射镜包括面向光源的光转向输入耦合元件，面向显示面板的光转向输出耦合元件和在输入和输出耦合元件之间的多层反射器。受控的传输镜横向扩展光，使得面板的照明更均匀。受控透射反射镜可以包括在输入和输出耦合元件之间的透明衬底，用于附加的光扩散。光源可以位于受控的透射镜内，而不是在其后面。输出耦合元件对极化不敏感，因此从受控透射镜反射出的光是非偏振的，或者输出耦合元件可以是偏振敏感的，使得输出光被极化。
