摘要： An autostereoscopic display comprises a pixellated transflective spatial light modulator which is arranged to provide a visual indication to an observer of the amount of crosstalk caused by reflection of ambient illumination. The display comprises a rear parallax barrier between a backlight and the modulator. Part of the barrier is formed as a screen blocking transmitted light from a first region of the modulator so that the pixels in this region are visible only by reflection of ambient illumination. In a second region, the pixels are illuminated with both transmitted and reflected light. A controller sets the pixels of the first region to maximum intensity and the pixels of the second region to a fraction of the maximum intensity. The fraction corresponds, for example, to a maximum amount of crosstalk which is permissible for autostereoscopic viewing. When the brightness of the first region is darker than or the same as the brightness of the second region, crosstalk is sufficiently low to permit autostereoscopic viewing.
摘要翻译：自动立体显示器包括像素化半透反射空间光调制器，其被布置为向观察者提供由环境照明的反射引起的串扰量的视觉指示。显示器包括背光源和调制器之间的后视差屏障。屏障的一部分形成为阻挡来自调制器的第一区域的透射光的屏幕，使得该区域中的像素仅通过环境照明的反射才可见。在第二区域中，像素被透射和反射光照射。控制器将第一区域的像素设置为最大强度，将第二区域的像素设置为最大强度的一部分。该分数例如对应于自动立体观看允许的最大串扰量。当第一区域的亮度比第二区域的亮度暗或相同时，串扰足够低以允许自动立体观看。

摘要： An optical device directs light from a light source to a region of space, such as the field of view of a camera when the optical device is used as a camera flash unit. This device includes a first optical element which converges light from the light source towards an inner portion of the region to be illuminated and a second optical element which diverges part of the light from the first element outwardly towards an outer portion of the region to be illuminated so as to achieve adequate central illumination with improved uniformity of illumination across the region to be illuminated. The second optical element may have a concave multiple-faceted surface comprising plane facets in the shape of an open-base inverted truncated pyramid, contiguous sector-shaped facets, at least some of which are concave, or a face divided into an elongate portion disposed between first and second diverging portions.

摘要： A parallax optic comprises plural, spaced apart lenses which are separated by regions which are non-tranmissive of/to visible light. In some embodiments, the spaced apart lenses of the parallax optic are discrete elements of a lens array. In other embodiments, the lens elements are formed as convex elements integral with and extending from a lenticular layer. Parallax optic devices are combined with one or more image display elements to form an image display device. For embodiments of image display devices featuring or providing two-dimensional (2D) viewability, the parallax optic is preferably near or included in the image display element. On the other hand, for embodiments of image display devices featuring or providing three-dimensional (3D) viewability, the parallax optic is situated outside the image display element.

摘要： A time-sequential colour projector comprises a pixellated light valve (2), such as a liquid crystal device, and a plurality of light sources (30, 31, 32). The light sources (30, 31, 32) direct light on different sets of pixels of the light valve (2) via an optical system (1), such as a lens array, which focuses the light on pixels of the light valve (2). At least two of the light sources (30, 31, 32) are multiple colour light sources and the multiple colour light sources emit different colour components during each set of frames making up a complete image frame.

摘要： A multiple view display comprises a display device which displays first and second images in a spatially multiplexed fashion across the display surface. The device cooperates with a parallax optic such as a lenticular screen so as to act as a directional display sub-system directing light from the first and second images in different viewing directions. An optical system, for example comprising a lenticular screen of diverging elements, changes the angular separation of the viewing angle directions, for example so as to increase the angular separation.

摘要： A directional backlight, a multiple view display and a multi-direction display A multiple view display (18) comprises a directional display device (19) for displaying a first image or sequence of images so as to be mainly visible from a first range of directions relative to the device and for simultaneously displaying a second image or sequence of images so as to be mainly visible from a second range of directions relative to the device different from the first range. The display (18) further comprises a directional backlight (20) for directing light through the display device (19) at least mainly in the first and second ranges. Since the directional backlight (20) directs light through the display device (19) at least mainly in the first and second ranges, the display provides users located in the first and second ranges with images of greater intensity than a conventional display. The backlight may be arranged to direct substantially no light in at least part of a third range of directions that lies between the first range of directions and the second range of directions. This provides a ‘black window’ between the first and second ranges in which the intensity of the display is lower than in other ranges. The intensity of the display in the black window is possibly zero, or close to zero, so that an observer located in this window will not perceive an image.
