See more at crystal Examples of liquid crystalliquid crystal Here we consider more practical situations where the electromagnetic field interacts with the liquidcrystal deformation. The behaviour of liquidcrystal materials used in display devices is discussed. As pointed out these solutions are very robust and are applicable to a wide range of liquidcrystal materials of practical interest. A confined nematic liquidcrystal is forced to display point or line singularities whenever the boundary conditions imposed on it are topologically nontrivial. This serves as an archetype for more complex but realistic liquidcrystal devices of practical importance. The optical properties of the device can be altered by applying a field whose distorting influence on the liquidcrystal opposes that of the surfaces. The theory assumes the interface to be fixed, as for a rigid cavity filled with liquidcrystal, and so it does not apply to drops. A systematic asymptotic analysis has been applied and solution derived for the practical range of three nondimensional parameters describing the liquidcrystal properties. Indeed, the ideal fibre-reinforced fluid may be regarded as a special and limiting case of a liquidcrystal as described by continuum theory. Decreasing means that the effect of flexoelectricity relative to elasticity within the liquidcrystal is decreased. The user wears a pair of stereo liquidcrystal shutter glasses and a six-degree-of-freedom head-tracking device. The equations governing the static behaviour of the liquidcrystal are obtained from (2.14), (2.15) by suppressing time derivatives. These results are important for optimizing the liquidcrystal materials used in electro-optic devices and demonstrate the potential for future modelling. The full expression for the torque on the liquidcrystal is the sum of the elastic and the electrostatic torques. The dynamics of liquidcrystal transitions is also important from a practical point of view as this determines switching times of electro-optic devices.
