摘要

Method of control of a matrix display screen making it possible to adjust its contrast, which consists in applying on the line conductors periodically of the addressing signals v1, having for a certain time a value vmax, in absolute value, to be applied to the column conductors of the control signals. It is applied on the line conductors of the addressing signals, the durations for which they have a value vmax partially overlap, for two consecutive lines. / p & & p & device for implementing this method. / p & & p & application to displays for the display of fixed or animated images.
