    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： A method comprising the following steps:(a) creating a thermal transfer donor sheet by vapor depositing a colorant layer onto a support;(b) contacting a receptor sheet with the donor sheet such that the colorant layer is in intimate contact with the receptor sheet, wherein at least one of the donor and receptor sheets comprises a radiation-absorbing material;(b) imagewise exposing the contacted sheets to radiation of a wavelength absorbed by the radiation-absorbing material, thereby causing heating in the exposed regions, said heating causing thermal transfer of colorant from the donor sheet to the receptor sheet in an imagewise fashion.

    摘要： Emissive displays can include a plurality of independently operable light emitters that emit light through one or more transmissive layers. The emissive displays further include elements disposed between the light emitters and the transmissive layers to frustrate total internal reflections that can occur at one or more of the interfaces created by the transmissive layers, such as at an interface between the light emitter and a transmissive layer or at an interface between a transmissive layer and air. By frustrating total internal reflections, the brightness of the emissive display can be enhanced. Elements for frustrating total internal reflections include volume diffusers, surface diffusers, microstructures, and combinations of these or other suitable elements.
