  • Patent number: 9244286
    Abstract: A multiple depth display provided for displaying images at different depths comprises a single display device (61), for displaying all of the images. An optical system (62, 63, 64) is disposed in front of the display device (61). The optical system comprises first and second spaced-apart partial reflectors (62, 63) and polarization optics (64) for providing first and second light paths for first and second images or sequences of images displayed by the device (61). The first light path (65) comprises partial transmission through the first reflector (62), partial reflection from the second reflector (63), partial reflection from the first reflector (62), and partial transmission through the second reflector (65) towards a viewing region.

  • Publication number: 20070216828
    Abstract: 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).

  • Publication number: 20070183015
    Abstract: A spatial light modulator comprises: a first substrate (25); a second substrate (26); a layer of electrooptic material disposed between the first substrate and the second substrate. A first electrode arrangement (27) is disposed over the first substrate (25); and a second electrode arrangement (35) is disposed over the second substrate (26). The first electrode arrangement (27) comprises first and second electrode layers (28,29) disposed over the first substrate, with the spacing between the first electrode layer (28) and the first substrate (25) being different to the spacing between the second electrode (29) layer and the first substrate (25). The first electrode layer (28) and the second electrode arrangement (35) are configured so as to co-operate, in use, to define a plurality of first addressable regions in the electrooptic material.

  • Publication number: 20060082702
    Abstract: An optical device comprises an input polariser 4, a patterned retarder 5 and an output polariser 12. The retarder 5 has regions 8 and 9, at least one of which alters the polarisation of light from the input polariser 4. The output polariser 7 has a transmission axis 12 such that light passing through the regions 8 and 9 of the retarder 5 and through the output polariser 7 is matched in amplitude, phase and polarisation. Such a device may be used as a switchable parallax barrier with an LCD 2 to provide a display which is switchable between an autostereoscopic 3D mode and a 2D mode with the 2D mode having more uniform intensity across the display.

  • Publication number: 20050063029
    Abstract: 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.
