摘要： A liquid crystal device is described that comprises a layer of liquid crystal material contained between a first cell wall and a second cell wall. The layer of liquid crystal material being switchable between at least a first state and a second state, said first state and said second state having sufficiently low splay to enable rapid electrical switching therebetween. The internal surface of said first cell wall is arranged to provide two or more surface alignment configurations of different pretilt to said layer of liquid crystal material. Said states may persist in the absence of an applied electric field. In particular, the invention relates to pi-cell devices that allow for rapid switching from the initial splay state to the bend states, and also to bistable or multistable pi-cell devices.

摘要： 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.

摘要： A method of addressing multistable nematic liquid crystal devices, in particular bistable nematic liquid crystal devices is provided. The method is a line at a time addressing scheme where one of at least two data waveforms is applied simultaneously to each of the column electrodes whilst a strobe waveform is applied to a row. The strobe waveform comprises a blanking portion sufficient to cause the liquid crystal material to blank, irrespective of which data waveform is applied, immediately followed by a discriminating portion which is such that in combination with an appropriate data waveform allows for selective latching. At least part of both the blanking portion and the discriminating portion are applied during the line address time for the particular row of interest.

摘要： A method of addressing bistable nematic liquid crystal devices is provided. The method is suitable for implementation using commercially available STN drivers. The method involves applying one of at least two data waveforms simultaneously to each column electrode whilst an active row waveform is applied to an active row and a non active row waveform is applied to all other rows. The resultant waveform at the pixels on the active row comprises a blanking portion sufficient to cause the liquid crystal material to blank, irrespective of which data waveform is applied, immediately followed by a discriminating portion which allows for selective latching depending on the data waveform applied.

摘要： A method and apparatus for forming a patterned layer having a surface profile that provides relief structures within an electronic device. The method comprises the steps of taking a carrier film (50) having an inverse of the required surface profile formed on one side thereof, taking a layer of fixable material (54) located on a substrate (52), laminating the carrier film (50) and substrate (52) such the carrier film causes the required surface profile to be formed in the layer of fixable material with a predetermined offset, and then fixing the fixable material. Lamination may be performed using rollers (56,58) or a vacuum process. The process is designed to ensure that the offset can be kept as low as possible, preferably to within 150 nm.
