摘要: A display is provided having first and second direct view modes of operation. The display comprises a liquid crystal display panel and a backlight which is illuminated during the first mode so that the displayed image is visible throughout an extended viewing region in front of the device. The display also comprises a holographic element and a front light source, which is switched on for the second direct view mode. The holographic element redirects light from the front light source into part of the extended viewing region so that an image displayed by the device is visible in only a restricted portion of the viewing region.

摘要: A display comprises a backlight (30, 45-48) and a spatial light modulator (1) such as a liquid crystal device for modulating light from the backlight (30, 45-48). The backlight has a light-output surface (45) with a first set of regions in the form of parallel evenly spaced strips (48). In a multiple-view mode of the display, these strips (48) emit light whereas the remainder of the output surface (45) is dark. In a single-view mode of operation of the display, the whole of the output surface (45) emits light substantially evenly across the display area of the modulator (1).

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: 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 display device is provided that comprises a liquid crystal display panel for displaying an image by spatial light modulation, and circuitry for switching liquid crystal in the panel between having a first configuration in a first mode to cause an image displayed using the panel to be discernible from a wide range of viewing angles, and having a second configuration in a second mode to cause an image displayed using the panel to be discernible substantially only from within a narrow range of viewing angles. Several types of display panel to achieve such in-panel switching between public and private viewing modes are disclosed.
