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.

摘要： To align a display substrate comprising an array of pixels with a component substrate comprising an array of optical components, the display substrate is divided from a display motherglass formed with an array of panels each comprising an array of pixels sufficient for a single display substrate and with, in respect of each panel, a first alignment feature having a surface relief aligned with the array of pixels. The component substrate is formed with an array of optical components and a second alignment feature aligned with the array of optical components, the second alignment feature having a surface relief shaped to register with the first alignment feature. The display substrates is attached to the component substrate with the first and second alignment features in registration with each other. The alignment of the first alignment feature with the array of pixels may be carried out at the motherglass stage in respect of the entire motherglass. The registration of the alignment features during attachment is a straightforward mating process which does not require precision alignment apparatus. Thus the yield can be increased.

摘要： An autostereoscopic display apparatus comprises a spatial light modulator comprising an array of pixels arranged in rows and columns in a pixel plane, and a spatially multiplexing parallax element capable of directing light from successive columns of pixels towards successive ones of two or more viewing windows in a nominal window plane. The pixels comprise pixel apertures having gaps therebetween with the gaps between the columns of pixels extending substantially parallel to the columns of pixels. The arrangement of the pixels is designed taking account of the intensity profile of an image of a nominal human pupil in the nominal window plane formed in the pixel plane by the spatially multiplexing parallax element to reduce the amount of spatially derived flicker observed by a viewer moving in the window plane. In one arrangement, the pixel apertures repeat at a pitch equal to a representative width of said intensity profile. In another arrangement, the total height of the pixel apertures parallel to the columns of pixels has a profile which increases towards the edges of the pixel apertures relative to the centre of the pixel apertures.

摘要： A light direction switching apparatus and method is described. The light direction switching apparatus comprises a passive birefringent lens (138), e.g. a birefringent lenticular screen, and a switchable polariser (146). By switching the polariser (146), different directional distributions of output light are provided. The light direction switching apparatus may be used with or incorporated in a display device, such as a liquid crystal display device, to provide a display device switchable between a two dimensional mode and an autostereoscopic three dimensional mode, or to provide a multi-user display device where different images are displayed to different viewers. The light direction switching apparatus may also be used to provide switchable brightness enhancement of reflective or transflective display devices. The light direction switching apparatus may also be used to provide a fibre-optic switching apparatus. The switchable polariser may be mechanically switchable or electrically switchable.

摘要： A light emitting diode package for a directional display may comprise light emitting diodes and a protection diode. The protection diode may be arranged in a well that is at a different location to the well that the light emitting diodes are arranged. The directional display may include a waveguide. The waveguide may include light extraction features arranged to direct light from an array of light sources by total internal reflection to an array of viewing windows and a reflector arranged to direct light from the waveguide by transmission through extraction features of the waveguide to the same array of viewing windows. The brightness of the directional display can be increased. An efficient and bright directional display system can be achieved. Efficient light baffling for light escaping from the edge of the waveguide is achieved through light deflecting extraction films.
