Abstract: A twisted nematic bistable liquid crystal (2) switching between two stable states in a high voltage mode is used in an AMLCD low voltage drive. The picture electrodes (14) and the counter electrode (15) are part of an active matrix, enabling the display to be used also in a fast video mode. Thus, a bistable liquid crystal display device is provided which has two drive modes, a low frequency mode, (first drive mode, also called “bistable mode”, “passive mode” or “high voltage mode”) for applications requiring slower switching times and lower power consumption and a high frequency mode (second drive mode, also called “active mode, “active matrix drive mode” or “fast video mode”) for grey scale images and video applications.

Abstract: A switchable transflector (1) comprises a suspended particle device (SPD). The transflector (1) may be switched into transmissive, reflective or intermediate states by applying one or more electric fields to a particle suspension (2). An enhanced reflectivity state may be achieved by applying two mutually orthogonal electric fields simultaneously. An intermediate state may be achieved by applying a non-saturating electric field or by applying two or more electric fields alternately according to a timing scheme. The transflector (1) may be maintained in a given state by applying voltage pulses at intervals less than a relaxation time associated with the SPD 1. The transmittance and reflectance properties of the transflector (1) may be tuned in accordance with the output of a light sensor (14). The transflector (1) may be incorporated in a transflective display (15)which comprises a display device, such as an LCD (16). In order to illuminate the LCD (16), the transflector (1) is arranged to transmit light (20) emitted by a light source (17) and/or reflect ambient light (21). The relative proportions of transmitted and reflected illumination may be determin by the output of the light sensor (14).

Abstract: The invention relates to an electro-optical cell (1) comprising a first (2) and a second (3) support member, an electro-optical medium (5) between the support members and an electrode arrangement (11, 12) on the support members such that an electric field can be applied, in the electro-optical medium, perpendicular to the support members, aligned with the support members or at an oblique angle (7) with respect to the support members. The electro-optical cell further comprises layers (14) of material with different dielectric constant between the support members in order to reduce the inhomogeneity of the electric field lines in the electro-optical medium. By having a layer of cholesteric liquid crystals between the support members, the electro-optical cell will function as a colour filter for varying applied fields. By introducing a particle suspension in a medium between the support members, an electro-optical cell is created that can be switched between a transmissive, reflective and partly deflective state.

Abstract: The invention relates to an optically anisotropic body, such as a compensation foil or a micro-lens array, having a desired pattern of optical properties. Said body is obtainable by a method wherein a non-uniform electric and/or magnetic field is applied over a body comprising a polymerizable electro-optical and/or magneto-optical material, such as a LC monomer, thus inducing a desired molecular pattern. The pattern is made permanent by polymerising the electro-optical and/or magnetooptical material.
