摘要： A display is provided having private and public viewing modes. The display comprises a display device and a parallax optic (3) comprising an array of parallax elements (4). Each of the elements (4) co-operates with a set of pixels (1,2) having at least one first pixel (1) and at least one second pixel (2). A line (23) passing through the centre (21) of each first pixel (1) and the centre (22) of the cooperating parallax element (4) extends into a first viewing region (20a). The parallax elements (4) re-strict viewing of the first pixels (1) to the first viewing region and permit viewing of the second pixels (2) in a second viewing region. The display device displays a private image in the private viewing mode by means of only the first pixels (1) and displays a non-private image in the public viewing mode by means of at least the second pixels (2).

摘要： A display comprises a parallax optic (2), such as a combined parallax barrier and lens array, and a pixellated display device (1). The pixels of the display device (1) are arranged as groups cooperating with a parallax element (4) of the parallax optic (2). Each group comprises a first pixel (A) aligned with the centre of the parallax element (4), second and third pixels (B, C) on either side of the first pixel (A), and fourth pixels (D) shared with adjacent groups and disposed outside the second pixels (B, C). The parallax elements (4) make the different pixels of each group visible in different viewing regions. A control arrangement selects regions of the display and selects different combinations of the pixels of each group for image display within respective regions so as to provide simultaneously-present different viewing modes having different viewing range characteristics.

摘要： A display comprises: a single-view image display panel (6); and a parallax optic (8) disposed over a display face of the image display panel for restricting the angular spread of light output from the display face of the image display panel. This enables light to be concentrated in a desired viewing angle range (66), and avoids a user (56) seeing unwanted reflections that may occur as a result of a greater viewing angle range (64) if the parallax optic (8) is not provided. The display may be used, as an example, in a motor vehicle to prevent unwanted reflections from the windscreen (62) of the vehicle.

摘要： A camera flash comprises a light guide arranged to extract light at least through one surface; and one or more light sources arranged, in use, to emit light into the lightguide. Each light source is an LED or a laser diode. The camera flash is connectable, in use, to drive circuitry, the drive circuitry being for driving the light source(s) to emit a pulse of light. The waveguide spreads out the light from the light source(s), so that a flash of light from the camera flash does not present a safety risk, while minimizing loss of the light from the light source(s). The camera flash can thus provide a high overall optical output, spread over an extended area (as defined by the waveguide). The lightguide may for example be disposed around a camera module of a mobile telephone camera.

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.

摘要： An illumination system (32) is provided for producing output light having a variable angular illumination range for illuminating a display panel (31) in a display device (30). The illumination system (32) comprises first and second light sources (34 and 36) and is operable selectively in a first mode in which the output light comprises light derived from the first light source (34) with substantially no light derived from the second light source (36), and in a second mode in which the output light comprises light derived from at least the second light source (36). The output light derived from the first light source (34) has a first angular illumination range and the output light derived from the second light source (36) has a second angular illumination range wider than the first angular illumination range. The first mode can be used as a private mode and the second mode can be used as a public mode. The private mode can be used to prevent widespread reading of information or images displayed using the display device (30).

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 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.
