    摘要： The present invention relates to a method of addressing a bistable matrix screen, in which the following two steps are reiterated:A. a disturbance signal is applied to each pixel of a marking area for a time t1, said disturbance signal being higher than a threshold signal such that each pixel of the area leaves its initial stable state, said disturbance signal being lower than a switching signal such that each pixel of the area having one of the stable states as its initial state does not switch into the other stable state, each pixel of the area then being in an intermediate disturbed state that is intermediate between the two stable states, and thenB. no signal is applied to each pixel of the area for a time t2 to allow each pixel of the area to return to its initial stable state.

    摘要： An electro-optical method and apparatus uses liquid crystals. The method includes the step of filling a space between two parallel transparent plates with a material which comprises molecules having nematic properties, the structure of the molecules initially defining a substantially rectilinear nematic director perpendicular to the plates. A structure is then conferred on the material defining a second nematic director curved at least once in a plane perpendicular to the plate by application of a high frequency electrical field to the material, such that the second nematic director arrives substantially perpendicularly at at least one of the two plates. A twist is imparted to the second nematic director along a component at right angles to said plane perpendicular to the plates to impart a twist in the second nematic director. Light is caused to arrive with an incidence substantially at right angles to one of the plates to pass through the material, a rotation of polarization of the light, at an outlet from the plates, depending on the twist imparted to the second nematic director.
