    摘要： A method for the control of a liquid crystal display that includes a matrix of pixels arranged in crossed lines and columns. A switching of state of the liquid crystal molecules, is controlled by application of an electrical control signal between two electrodes (50, 52) framing each pixel, generates a flow according to a particular direction (18), characterized in that, to control the switching of at least some of the pixels (P). The method includes applying to at least one neighboring pixel (58), according to the direction of flow, of a pixel (P) whose switching is controlled by the electrical control signal, auxiliary electrical signals whose amplitude is less than the anchorage breaking voltage and whose rising or falling edges are temporally placed in advance or in coincidence with the active falling edge of the electrical control signal, to favor the switching of the said pixel to be controlled (P).

    摘要： The invention relates to a nematic liquid crystal display having two stable states, without an electric field, obtained by anchoring break, characterized in that it comprises two polarizers (10, 40), one (10) of which is placed on the observer side, the other (40) being placed on the opposite side of the liquid crystal cell whereby the latter is at least partially reflecting in order to define a reflective mode or transflective mode. The orientation of the two polarizers (10, 40) is offset by a value which is equal to the rotatory power of the cell at approximately +/−30°.

    摘要： A device nematic liquid crystal display device has two stable states corresponding to two liquid crystal molecule textures whose torsion differs by 150° to 180° in terms of absolute value. The device includes two polarizers (10, 40), one (10) of which is placed on the observer side, the other (40) being placed on the opposite side of the liquid crystal cell. The orientation of the two polarizers is offset by a value which is equal to the rotatory power of the cell+/−Π/2, the rotatory power corresponding to the most twisted texture effect.
