摘要： In a method of operating a liquid crystal device having a liquid crystal composition with smectic-A properties, a first waveform is applied to optically clear the device so that it is substantially transparent to visible light and a second waveform is applied to disorder the material of the liquid crystal composition to afford a strongly light-scattering state. The first waveform has a higher frequency than the second, waveform, and the method comprises applying a modified waveform to partially clear at least a portion of the device from the light-scattering state

摘要： A display includes a point source (1, 5) of activation radiation, or an array of such sources, a lens system (3) for collimating the radiation from the point source or array, a modulator (7) capable of controlling the transmission of the collimated excitation radiation, and a screen (13) capable of emitting a visible display when struck by the modulated activation radiation and since the light is produced by point sources, such as LEDs, accurate collimation can be achieved with no loss. This in turn means that the modulated light can be expanded to produce a seamless tiled display.

摘要： A display includes a layer of NCPT liquid crystal material (1) capable of modulating both internal UV radiation (20) and ambient light (30) impinging on the device from the viewing side, in order to combine an emissive function with a reflective function. For emission the UV radiation is selectively applied to phosphors (11) on the viewing side, while for reflection the ambient light is selectively reflected by the liquid crystal. The two functions operate together as each display cell is switched between an "off" state in which ambient light penetrates the display, being absorbed in a black background (25), while the input radiation is prevented from reaching the phosphors and hence from causing output, and an "on" state in which the ambient light is scattered from the liquid-crystal layer (thus being visible in daylight) and the input radiation (20), likewise scattered, reaches the phosphor (11) and causes it to emit (thus being visible in the dark).
摘要翻译：显示器包括能够从观察侧调制照射到装置上的内部UV辐射（20）和环境光（30）的NCPT液晶材料层（1），以将发射功能与反射功能组合。为了发射，UV辐射被选择性地施加到观察侧的磷光体（11），而对于反射，环境光被液晶选择性地反射。两个功能一起工作，因为每个显示单元在环境光穿透显示器的“关闭”状态之间切换，在黑色背景（25）中被吸收，同时防止输入辐射到达荧光体并且因此导致输出，以及环境光从液晶层散射（因此在日光下可见）的“开”状态，同样散射的输入辐射（20）到达荧光体（11）并使其发射（因此在黑暗中可见）。

摘要： In an active back-plane co-ordinate addressed liquid crystal cell exhibiting an analogue optical response to the application of an analogue electric potential, refreshing is carried out in two sequential stages in order to avoid cumulative charge imbalance effects. In one stage the pixels are set to their required optical states using the appropriate applied potential differences, and in the other stage the pixels are set with the same potential differences, but applied the other way round.

摘要： The present, invention relates to liquid crystal compositions having a smectic A structure for use in an optical device in which the composition is sandwiched between a pair of electrodes ( 12- 15). In essence the composition includes a siloxane oligomer (component (a)) which may be seen to construct a layered SmA system of particular spacing and "strength". Within this structure a low molar mass nematic mesogen (component (c)) is provided that may be considered to be that of a "plasticiser" which moderates the layer "strength", while simultaneously providing tuneability to the properties of the composition, e.g. its refractive index or dielectric anisotropy. The addition of a side chain liquid crystal polysiloxane (component (d)) allows such systems to be further moderated since they can be considered as binding together the la>¾rs, both within a given layer and between layers. An ionic dopant (component (b)) is also included in the composition that migrates through the composition when low frequency electric fields are applied to the composition by the electrodes, thereby disrupting the order to the composition. Order in the composition can be restored by applying a higher frequency field that does not allow the dopant time to migrate significantly. Chromophores may also be included in the formulation.

摘要： A liquid crystal device is disclosed with a layer of liquid crystal, at least one non-liquid-crystal particle (e.g. nano scale) held in the liquid crystal and a substrate on which an array of electrodes is formed. The device is operable to apply a desired potential to each electrode. The potential applied to each electrode is controllable to affect the director of at least a region of the liquid crystal layer local to each said electrode and thereby to form at least one disclination in the liquid crystal layer. The device is also adapted to controllably move the particle due to an interaction between the particle and the disclination and by control of the potential applied to said electrodes to control the disclination.

摘要： A liquid crystal structure (200) comprising first and second reflective regions (214a, 214b, 214c) arranged to reflect respective first and second colours. The first and second reflective regions (214a, 214b, 214c) are disposed transversely to the direction of reflection (R). Each region includes a reflective back area and a selector (210) controllable to control light reflected from the region. Furthermore, a controllable reflector (212) is superposed over the reflective region in the direction of reflection (R) and controllable to transmit or scatter incident light.
