DISPOSITIF AFFICHEUR A CRISTAL LIQUIDE COMPRENANT DES MOYENS PERFECTIONNES DE COMMUTATION
Abstract:
The invention relates to a method for controlling a liquid crystal display, comprising a matrix of pixels arranged in crossed lines and columns and in which a switching of the state of the molecules of liquid crystals, controlled by application of an electric control signal between two electrodes (50, 52) enclosing each pixel which brings about a flow in a given direction (18), characterised in comprising, for controlling the switching of at least some of the pixels (P), a step of applying to at least one adjacent pixel (58), according to the direction of flow in a pixel (P) the switching of which is to be controlled by the electric control signal, auxiliary electric control signals, the amplitude of which are less than the anchoring break voltage, the rising or falling fronts of which are temporally in advance of or coincident with the falling active front of the electric control signal, such as to promote the switching of said pixel (P) for control. The invention further relates to a display.
