摘要： An immersive display system is disclosed that includes screens configured to mitigate reduction in contrast ratio due at least in part to peripheral light incident on the screens. The immersive display system includes at least one screen having an array of micro-lenses, a light polarization layer on top of the array of micro-lenses, a polarization rotation layer, a light reflection layer, and a section of non-polarizing light scattering material for individual micro-lenses in the array of micro-lenses. In use, light from a projector associated with the screen is substantially scattered by the non-polarizing light scattering material and light from a projector associated with a different screen in the immersive display system is substantially absorbed by the polarization layer.

摘要： A display system that is adapted to provide control blow-by. The display system includes a projector that is operable to project light through a lens. The system also includes a first polarizer positioned proximate to the lens receiving and first polarizing the projected light. The display system further includes a projection screen assembly that includes a transparent projection screen and a second polarizer. The projected light first strikes the transparent projection screen causing a projected image to be displayed. The second polarizer is adapted to second polarize the projected light to provide cross-polarization and reduce blow-by in the display system. The first and second polarizers are configured with first and second axes of polarization, and the first and second polarizers are arranged in the display system with the first axis of polarization substantially orthogonal to the second axis of polarization to provide full cross-polarization of the projected light.

摘要： A directional polarization preserving front projection screen may be preferably produced using an engineered surface. Unlike statistical surfaces, engineered surfaces may provide locally specular reflections, with little to no bulk scatter, while substantially eliminating features smaller than a wavelength of illumination and thus true depolarization. Most, if not all, contours contributing to the slope probability density can be engineered to achieve a desired macroscopic gain profile. The screen may diffuse light by using locally specular reflections, in which a bias angle introduced to the gain profile of the screen may be determined by the slope of the ramps, and with resets that may be substantially hidden from projector illumination.

摘要： A method for providing a projection screen for receiving stereoscopic images may include providing a substrate with a contoured, reflective surface, wherein light reflected from the substrate substantially may undergo no more than a single reflection and may also include coating a first layer on the substrate with a contoured, reflective surface. The first layer may substantially maintain the same optical properties as the substrate without the first layer. The first layer may be substantially conformal to the surface of the substrate and also may be a self assembled monolayer coating which may include at least a functional group that is hydrophobic.

摘要： Polarization preserving projection screens provide optimum polarization preservation for 3D viewing. The projection screens additionally provide improved light control for enhanced brightness, uniformity, and contrast for both 2D and 3D systems. Generally, the disclosed method for providing a projection screen comprises embossing at least a first side of a first substrate to produce an optically functional material and then cutting the optically functional material into pieces to produce a plurality of engineered particles. The plurality of engineered particles may then be deposited on a second substrate to produce a substantially homogeneous optical appearance of the projection screen.
