    • A repeated pattern layer having areas for imparting different electro-optic characteristics to a light modulating device is disclosed. The repeated pattern is arranged so that any pixel area formed in the assembled device (above a certain minimum size) will contain an area of each electo-optic characteristic in the right proportions. The pattern is arranged as a two dimensional grid of areas of different characteristic with at least one area of each characteristic provided in each row and column of the grid.The patterned layer may usefully be an alignment layer for a liquid crystal device, especially a bistable device, and the different areas may be arranged to give grey scale in the device.

    • A rotary switch convertible from being operable over a smaller range of angular motion, e.g. as a two-position switch, into being operable, in either of two configurations, over larger ranges of angular motion, e.g. as a three-position switch. A rotor and a stator are assembled for relative rotation. Four lugs divide a face of the stator into four quadrants. Two pairs of lugs, each comprising a removable lug and a permanent lug, are provided on a face of the rotor. The faces are juxtaposed such that relative rotation of the rotor and the stator is limited by interference between certain of the lugs on the rotor and certain of the lugs on the stator. Before removal of either removable lug, the rotor and the stator may be assembled for a smaller range of angular motion. After removal of both removable lugs, the rotor and the stator may be assembled in either of two configurations for larger ranges of angular motion.

    • This invention relates to a liquid crystal device wherein the surface profile of a surface alignment grating stabilises at least one stable state. The invention involves the introduction or breaks (34, 36, 38) or discontinuities into the grating (10) to divide the grating into a plurality of groove segments. The breaks are discontinuities in the grating in the groove direction, the grating having substantially the same groove direction on each side of the break. The introduction of breaks prevent free movement of defects along the groove of the grating and therefore help to stabilise the desired liquid crystal configuration, either a Defect state or a Continuous state. Suitable breaks involve gaps (34) in the groove ridges (30), necks (36) between the groove ridges (30) and slips or relative displacement (38) of the grating.
    • 本发明涉及一种液晶显示装置,其中表面对准光栅的表面轮廓稳定至少一个稳定状态。 本发明涉及到光栅(10)的引入或断开(34,36,38)或不连续,以将光栅分成多个凹槽段。 断裂在光栅中的凹槽方向是不连续的,光栅在断裂的每一侧具有基本上相同的凹槽方向。 引入断裂防止缺陷沿光栅槽的自由移动,从而有助于稳定所需的液晶结构,即缺陷状态或连续状态。 合适的断裂包括槽脊(30)中的间隙(34),凹槽脊(30)之间的颈部(36)和光滑的相对位移(38)。
