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 display apparatus has a switchable birefringent lens array. The lens array comprises birefringent material arranged between a planar surface of a first substrate and a relief substrate of a second substrate defining an array of cylindrical lenses. The birefringent material can be switched electrically between a first mode in which the lens array has a lensing effect and a second mode in which the lensing effect is substantially absent. The director of the birefringent material may be arranged to lie in the plane of the substrates (twisted nematic orientation), or the director may be aligned homeotropically at the relief surface. The lens array may be located between a spatial light modulator and the output polariser of the display apparatus. The spatial light modulator may be emissive. Variations in the lens temperature may be compensated for in order to extend its operating range.

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： 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： The LEDs (72,74) are fabricated as a monolithic structure on a semiconductor wafer and are separated by sawing, cutting etc. Selected non-adjacent LEDs are removed from the diced monolithic wafer and transferred to a heat dissipating substrate in a single process step whilst maintaining their relative positions and separations. An array of lenses 122, 124 or reflectors is also transferred onto the LED assembly formed on the heat dissipating substrate. The LEDs typically have dimensions of 25-100 microns which reduces losses due to internal reflection and increases light output. The density of the LED assembly on the heat dissipating substrate is smaller than the density of the LEDs as formed on the monolithic wafer, maintaining the relative positions and orientations of the transferred LEDs in this way ensures that heat can be effectively removed from the LEDs. The manufacturing efficiency is improved in comparison with conventional pick and place techniques where individual LEDs from the monolithic wafer are selected and transferred to an LED array substrate in a sequential manner. The light emitting elements have a width/diameter of less than or equal to 300 micrometers.
