Abstract: Enhanced uniformity backlights and methods of assembling a backlight are disclosed. The backlights maintain light uniformity by generating a plurality of images of a linear light source instead of by increasing the number of light sources. A microstructured film receives light from the linear light source and refracts the light to an image receptor. The microstructured film includes an array of microstructures that have a symmetry that provides multiple images of the light source. The positioning and brightness of the images on the image receptor is dependent on the microstructure and the orientation of the microstructure to the linear light source. A method is disclosed to identify the relative orientation of symmetric microstructures which can provide more uniform images of the linear light source.

Abstract: An optical film for use in transparent displays, such as reflective LCDs. The optical film has three-dimensional, prismatic structures that reflect incoming light. The prismatic structures are configured so that the reflecting facets orient the reflected light in desired reflective light pattern. The pattern shape and intensity can be controlled by the shape and dimensions of the various reflecting facets. In one embodiment, the height of the prismatic structure varies along two dimensions of the structure.

Abstract: A directly illuminated display unit has a display panel and one or more light sources disposed behind the display panel. A diffuser is disposed between the one or more light sources and the display panel, and a light diverting layer is disposed between the one or more light sources and the diffuser. The light diverting layer has a first light-diverting surface facing the one or more light sources and a second light diverting surface facing the display panel. The light diverting layer diverts light passing from the one or more light sources to the diffuser, thus improving the uniformity of the light in the display unit.

Abstract: A display system (100) has a semi-transmissive mirror (120) disposed between the light sources (116a, 116b) and the display panel (102). The semi-transmissive mirror includes a light-diverting input coupling element (206) facing the light sources, a light-diverting output coupling element (208) facing the display panel and a multilayer reflector (204) between the input and output coupling elements. The semi-transmissive mirror laterally spreads the light, making the illumination of the panel more uniform. The semi-transmissive mirror may include a transparent substrate (202) 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 (208) element can be non polarizing, so the light passing out of the controlled transmission mirror is unpolarized, or it can be polarizing so that the output light is polarized.

Abstract translation: 显示系统（100）具有设置在光源（116a，116b）和显示面板（102）之间的半透射反射镜（120）。 半透射反射镜包括面向光源的光转向输入耦合元件（206），面向显示面板的光转向输出耦合元件（208）和在输入和输出耦合元件之间的多层反射器（204）。 半透射镜横向扩散光，使得面板的照明更均匀。 半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（202），用于附加的光扩展。 光源可以位于受控的透射镜内，而不是在其后面。 输出耦合（208）元件可以是非偏振的，因此通过受控透射反射镜的光是非偏振的，或者它可以是偏振的，使得输出光被极化。
