摘要： Disclosed is an optical valve or light valve for providing large area collimated illumination from localized light sources, and system and method thereof for 2D, 3D, and/or autosteroscopic displays. An optical valve may include a stepped structure, in which the steps include separated extraction features which may be optically hidden to light propagating in a first direction. Light propagating in a second direction may be refracted, diffracted, or reflected by the features to provide illumination beams exiting from the top surface of the optical valve. Such controlled illumination may provide for efficient, multi-user autostereoscopic displays as well as improved 2D display functionality.

A layer of isotropic material having an outer surface which is shaped with a surface relief structure and is provided with a liquid crystal alignment property is formed. A flexible sheet having an outer surface provided with a liquid crystal alignment property is formed. A curable birefringent liquid crystal material is applied to one or both of the layer of isotropic material and the flexible sheet. The flexible sheet is applied over the layer of isotropic material with the outer surfaces of the layer of isotropic material and the flexible sheet facing one another with the liquid crystal material therebetween, thereby to form a liquid crystal cell. The liquid crystal material is cured and the flexible sheet is removed from the liquid crystal cell.

摘要： A birefringent lens structure comprises a birefringent lens array capable of directing light of a given polarisation into a directional distribution, the birefringent lens comprising a solid birefringent material and an isotropic material having an interface having a refractive structure. A switchable liquid crystal layer capable of rotating the polarisation of light passing therethrough is arranged adjacent the first birefringent material. The interface between the birefringent material and the liquid crystal layer has an alignment microstructure providing alignment of the birefringent material and the liquid crystal layer. A pair of electrodes for applying an electric field to switch the liquid crystal are arranged with both the lens array and the switchable liquid crystal layer therebetween and a conductive material is incorporated in the lens array to reduce the voltage drop across the lens array. To reduce reflection, the interface between the birefringent material and the isotropic material has an interface having alignment microstructure providing alignment of the birefringent material, and the refractive index of the isotropic material is substantially equal to the extraordinary refractive index of the birefringent material.

摘要： A directional display apparatus, comprising a spatial light modulator comprising an array of pixels and a lens array in which each respective section of the lens array is capable of directing light from a group of pixels aligned with the respective section into nominal viewing windows, is arranged such that each respective section is also capable of directing light from at least one adjacent group of pixels aligned with a section adjacent the respective section into the same nominal viewing windows. This may be achieved by a deflection element, such as a prism element or a hologram, or by each respective section of the lens array having at least one lens surface providing: at least one first region capable of directing light from said group of pixels aligned with the respective section into said nominal viewing windows; and at least one second region capable of directing light from said at least one adjacent group of pixels into the same nominal viewing windows. By mixing light from adjacent groups of pixels, striped visual artefacts are reduced.

摘要： A stereoscopic display comprises a spatial light modulator such as a liquid cryatal device. The modulator comprises an array of pixels such as RGB pixels. A retarder array is disposed on the front of the spatial light modulator. The array comprises first stripes and second stripes which extend vertically and alternate which each other horizontally. The first and second stripes supply light from the modulator to an observer with different, preferably orthogonal, polarizations. Each of the stripes has a width which is greater than the horizontal pitch of the pixels. In a preferred embodiment, a lenticular screen is disposed in front of the retarder array. The lenticules extend vertically and are spaced horizontally with a pitch which is substantially equal to the pitch of the pixels.
