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 switchable imaging device (1) has a first mode of operation in which the device performs an imaging function and a second mode of operation different from the first mode, for example a non-imaging mode. In the first mode of operation the device comprises at least one first region that performs a lensing action and at least one second region that at least partially absorbs light passing through the or each second region. The switchable imaging device (1) may be disposed in path of light through an image display panel (4). This provides a display that may be operable in either a directional display mode such as an autostereoscopic 3D display mode or a 2-D display mode, by controlling the switchable imaging device to be in its first mode or its second mode.

摘要： A liquid crystal device comprises a first alignment surface which induces a high pretilt greater than 45° but less than 90°; a typical value is 85°. The pretilt has a component parallel to the surface pointing in a predetermined direction. A second alignment surface induces a low pretilt which is less than 45° but greater than 0°; a typical pretilt is 5°. The low pretilt has a component parallel to the second surface which also points in the predetermined direction. A layer of crystal material is disposed in between the first and second surfaces. A novel liquid crystal mode is thus provided and is referred to as the “splay-twist mode”. Such a device may be used in a switchable public/private display.

摘要： A display is provided having a public viewing mode and a private viewing mode. The display comprises a display device (11), such as an LCD, which directs image-modulated light towards the whole of a public viewing region. The display device (11) displays a first image in the public mode and second and third spatially interlaced images in the private mode. A controllable liquid crystal device (10) is switchable between the public and private modes. In the public mode, light modulated by the first image has a first polarisation. In the private mode, light modulated by the second and third images is provided with second and third polarisations, respectively. An optical arrangement, comprising an angularly dependent polarisation changer (9) and a polariser (8) permits the passage of light of the first polarisation into substantially the whole of the public region. Light of the second polarisation is substantially restricted to a private viewing region within the public region. Light of the third polarisation is substantially restricted into one or more non-private viewing regions outside the private region and within the public region.

摘要： A liquid crystal device comprises an active matrix substrate (6) and a counter-substrate (7) provided with homeotropic alignment surfaces (11). A layer of nematic liquid crystal material is provided between the alignment surfaces (11) so as to form a vertically aligned nematic device. The substrates (6, 7) carry a pixel electrode arrangement and a counter-electrode arrangement which define a plurality of pixel regions. Each of least some of these regions has a pixel electrode (13), which may be split into two halves, and a counter-electrode (8) which are arranged to apply an electric field for controlling the liquid crystal director (12) out-of-plane tilt angle. A further electrode (14), for example in the form of a plurality of parallel fingers, cooperates with at least one of the other electrodes (8, 13) to apply a second electric field for controlling the director in-plane azimuth angle. Such a device may be used, for example, as a switchable public/private display.
