    摘要: A display device comprises a source 1 of light of a first polarization, a source of light of a second polarization different from the first polarization, an optical system arranged to image the light emitted by the light sources through a spatial light modulator (SLM) to produce an image of the source of light of the first polarization at a first viewing zone and an image of the second source of light at a second viewing zone, the SLM including a plurality of picture elements arranged to modulate the light emitted by the sources of light, and a plurality of polarization adjusting means each being optically aligned with at least one respective picture element, the polarization adjusting means comprising a first group arranged to permit the transmission of light of the first polarization and substantially prevent transmission of light of the second polarization, and a second group arranged to permit the transmission of light of the second polarization and substantially prevent transmission of light of the first polarization such that the image on the SLM which can be viewed from the first viewing zone is that of the picture elements optically aligned with the polarization adjusting means of the first group and the image which can be viewed from the second viewing zone is that of the picture elements optically aligned with the polarization adjusting means of the second group. The polarization adjusting means may comprise an array of polarizing elements 5a, 5b, or alternatively may comprise an array of wave plates 33. The optical system may comprise a lens 3 or array of lenses provided between the light sources 1, 2 and the SLM 4. A spatial light modulator which may be used in 3D displays of stereoscopic or autostereoscopic type comprises substrates (19, 21) between which is disposed a liquid crystal layer (20). The layer comprises two sets of pixels (12, 13) for displaying left and right eye images. A pixellated polarisation adjustor (31, 32; 33, 34) is disposed between one of the substrates (21) and the liquid crystal layer (20) so as to minimise parallax effects. The pixels (12, 13) of the liquid crystal layer (20) are operated in the same mode i.e. all normally black or all normally white.

The display element (10a, b, c, 30a, b, c, 56) defines a plurality of sub-elements (24a, b, c, 46a, b, c, 50, 52, 54), the liquid crystal material (22, 44) of each of which is switchable between its stable states upon the application of a voltage exceeding a predetermined level to the first and second electrodes (18, 20, 36, 38). The liquid crystal material (22, 44) has a minimum in its response time - voltage characteristic. In one embodiment, the liquid crystal material (22) is of stepped thickness so that the sub-elements (24a, b,c) have different liquid crystal layer thicknesses.

    摘要: A liquid crystal display comprises, in order from the viewing side, a first glass substrate 10 carrying an electrode 12, a dichroic liquid crystal layer 16 provided with suitable alignment layers 14, 18, a half wave retarding layer 30, a quarter wave retarding layer 20, a reflector 24 and a second glass substrate 28 carrying an electrode 26. In use, in one of its states, the dichroic liquid crystal layer 16 absorbs a component of the light incident thereon, the transmitted component being plane polarised. The polarised light is incident upon the retarding layer 20 which converts the plane polarised light to circularly polarised light, this light being reflected and converted back to plane polarised light polarised in a direction perpendicular to the original plane of polarisation on returning through the retarding layer 20. Such polarised light is absorbed by the dichroic dye, no light being transmitted by the cell towards the viewer. The presence of the layer 30 improves the achromaticity of and light absorption in the dark state. In another state, the dichroic dye does not absorb, and hence does not polarise, the light, the cell then transmitting light to the viewer.

    摘要: An integrated electro-optical device comprises a pixellated liquid crystal modulation layer (6) superposed over an electronic detection layer (3). Modulator pads (12) for the liquid crystal layer (6) may be formed as electrically conductive combs to achieve optical polarisation. Where the liquid crystal layer provides selective absorption of unpolarised light, and separate polarisers between the liquid crystal and detection layers are therefore unnecessary, the device comprises such a liquid crystal layer (6) superimposed over the electronic detector layer (3).
    Further, an integrated electro-optical device, optionally of the above type, has a plurality of pixels (A', B') of the liquid crystal layer for each pixel (AB) of the detector array. This allows optical shuttering of the detector pixels by electrically modulating the pixellated liquid crystal layer (6).
