摘要： Disclosed is a rear projection screen that includes a plurality of tapered waveguides and a light absorbing layer disposed over the tops of the waveguides, but that does not completely fill the spaces between the waveguides, thereby forming an interstitial low index region under the light absorbing layer and between the waveguides. The low index interstitial region can include air or a material that has a lower index of refraction than the waveguide material. This rear projection screen construction can give rise to increased efficiency and higher contrast, as well as allow for more design freedom in constructing screens that have desired characteristics such as viewing angle, viewing asymmetry, and the like. Also disclosed are methods for making the described microstructured rear projection screen.

摘要： An optically dispersing film for a rear projection system includes reflecting surfaces disposed so as to reflect light passing therethrough into at least one dispersion plane. The reflecting surfaces are formed by structures, of a first refractive index, disposed within a layer of material having a second refractive index. The structures have light absorbing bases at the viewing side of the film. In some embodiments, the reflecting surfaces are disposed at one or more angles so as to reflect light into a number of different directions. In other embodiments, the layer of material having the second refractive index includes diffusing particles that diffuse the light. The film permits the asymmetric dispersion of image light in a rear projection system, so that the light may be selectively directed towards the viewer.

摘要： Rear projection screens use lenticular lens films as light dispersing components. A single lenticular lens film includes lenticular lenses having different focal powers, or includes lenticular lenses formed in two dimensional patterns. The lenticular lens films improve the brightness uniformity over the entire screen as viewed by a viewer who is located at a specific position. The specific position is typically selected to be the most probable location of the viewer for the particular application.

摘要： Rear projection screens include a film layer having a plurality of lenses for diverging light horizontally and vertically. The horizontal viewing angle created by the lenses may be different from the vertical viewing angle. The light may be directed by the lenses in a particular direction, so that the direction of the maximum intensity light does not lie parallel to an axis normal to the screen surface. The lens film may be combined with an isotropic light disperser, such as a bulk diffuser.

A plurality of second light sources is arranged along the second side of the light guide for transmitting light into the light guide from the second side. The second surface includes a regular array of linear prism or lenticular features. A double sided prism film is disposed between the liquid crystal display panel and the regular array of linear prism or lenticular features.

The autostereoscopic display apparatus includes a backlight having opposing first and second light input surfaces and a light transmission surface extending between the opposing first and second light input surfaces and a right eye light source located to provide light into the first light input side and a left eye light source located to provide light into the second light input side, wherein the left eye light source and the right eye light source are configured to be modulated between the left eye light source and the right eye light source at a rate of at least 90 hertz. A double sided prism film is adjacent to the light transmission surface. The double sided prism film has a plurality of linear prism features on a first major surface and a plurality of lenticular features on a second major surface. The first major surface opposes the second major surface. The double sided prism film is disposed between the light transmission surface and a Fresnel lens element. A liquid crystal display panel is positioned to receive light transmitted through the double sided prism film.
