    Abstract: 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.

    Abstract: A liquid crystal smectic A composition that can be switched by the application of different electric fields across it between a first stable state (left hand block in FIG. 4) and at least one second stable state (right hand block in FIG. 4) in which the composition is less ordered than in the first state. The radiation transmission properties of the first and second states are different. The composition comprises: (A) a liquid crystal material that has a positive dielectric anisotropy and that is a uniformly aligned smectic A structure when in the first state; (B) an ionic dopant giving a negative conductivity anisotropy in the liquid crystal material so that it is capable of disrupting the smectic A structure of the first state when subject to an electric field that causes the dopant to migrate through the composition, thereby causing the composition to switch into said at least one second state, and (C) optically anisotropic pigment particles having positive dielectric anisotropy dispersed in the composition, the largest dimension of the pigment particles being in the range of 10 nm to 1 μm. The composition, when in the first relatively stable state, is capable of undergoing smectic dynamic scattering due to electro-hydrodynamic instability under the influence of a sufficiently low frequency AC field, thereby disordering the liquid crystals and the pigment particles and thereby discouraging the pigment particles from aggregating together. The composition is suitable for use in displays and is especially resistant to degradation by ambient light and so can be used in outside applications.

    Abstract: A display device includes a shutter layer of liquid-crystal material arranged in cells to shutter input light selectively, a cover layer 5 on the shutter layer, and a set of phosphors 7 on the cover layer, corresponding to the cells, to be activated by the input light and provide the display image. To prevent crosstalk the active cell areas 10 defined by the electrode overlaps are smaller than the corresponding phosphors. This prevents crosstalk between cells even when input light that is not fully collimated is used and also allows space for thicker and/or broader electrodes 12 leading to the cells, reducing resistance, and for other components such as TFTs.
