摘要： An autostereoscopic display comprises an SLM which is controlled to provide an image display and a signal display. A parallax optic has a first portion which cooperates with the image display to form a plurality of viewing windows. A second portion of the parallax optic forms first and second images visible to an observer at alternate viewing windows so as to allow the observer to distinguish between desired orthoscopic viewing zones and undesirable viewing positions such as pseudoscopic positions.

摘要： An observer tracking display is provided in which the image data displayed by at least three image displays along respective different directions is updated depending on the lateral position of an observer. The image displayed in a viewing region not visible to the observer is updated with an appropriate image in anticipation of the observer moving to a position where that viewing region is visible.

摘要： A parallax barrier includes a polarisation modifying layer having aperture regions, for supplying light of a second polarisation when receiving light of a first polarisation, separated by barrier regions, for supplying light of a third polarisation different from the second polarisation when receiving light of the first polarisation, and a polariser selectively operable in a first mode and a second mode. At least one of the aperture regions and the barrier regions alters the polarisation of light passing therethrough. The polariser passes light of the second polarisation and blocks light of the third polarisation in the first mode and passes light of the third polarisation in the second mode.

摘要： An autostereoscopic 3D display includes a spatial light modulator, for instance of the liquid crystal display type. A backlight and a mask form a plurality of light sources which are imaged by a lenticular screen at first notional viewing windows. A parallax barrier controls the visibility of pixels of the spatial light modulator to form second notional viewing windows. The display forms actual viewing windows whose lateral extent is equal to the product of the lateral extents of the first and second viewing windows and is less than each of these lateral extents.

摘要： A directional display comprises a display arrangement such as a spatial light modulator and a rear parallax barrier illuminated by a suitable backlight. The spatial light modulator and the parallax barrier cooperate to produce Fresnel diffraction which results in spatially non-uniform brightness across viewing windows of the display. Also, where the spatial light modulator has pixels of non-constant vertical aperture, further variations in the intensity profile at the windows occurs. In order to compensate for this, a mask is provided, for instance between the parallax barrier and the backlight. The mask cooperates with the parallax barrier to produce an intensity pattern having variations which are the inverse of the variations in intensity pattern produced by the parallax barrier and the spatial light modulator. The variations are superimposed and substantially cancel each other out so as to result in viewing windows which have substantially uniform light intensities.

摘要： A passive polarisation modulating optical element comprises a layer of birefringent material. The layer has substantially fixed birefringence and comprises retarder regions forming a regular pattern, for instance to act as a parallax barrier for a 3D display. The retarders have optic axes aligned in different directions from each other. The element may be associated with a polariser, for instance an output polariser of a liquid crystal device, with the polarising direction of the polariser being parallel to the optic axis of the retarders. Thus, the retarders have no effect on the intensity of light passing through the element whereas the retarders act as half waveplates and rotate the polarisation vector of light passing therethrough, for instance by 90.degree..

摘要： A spatial light modulator comprises a plurality of picture elements arranged as rows and columns. The columns are arranged as adjacent groups, for instance for association with an element of a parallax device to provide an autostereoscopic 3D display. Adjacent picture elements disclosed in each row and in adjacent columns of each group overlap horizontally so that there are overlapping regions and non-overlapping regions. The vertical extent of each picture element is substantially constant throughout the non-overlapping region and is substantially equal to the sum of the heights of the adjacent picture elements throughout the overlapping regions.
