Abstract: A process for compensating a circuit including at least one first conductor with a specified potential, at least one second conductor generating disturbances on the first conductor by capacitive coupling, and a first bus with a reference voltage, coupled capacitively to the first conductor. The process includes the following steps: measuring of the current flowing on the first bus upon the application of a voltage to the second conductor; integrating a measured current to obtain a compensation voltage to be applied to the first conductor; and applying the compensation voltage to at least one of the rows via the compensation conductor bus, the compensation bus coupled capacitively to the rows.

Abstract: The present invention relates to a process for displaying data on a matrix display consisting of N data lines and P selection lines at the intersections of which are situated the image points or pixels. The N data lines are grouped into {dot over (P)} blocks if N′ lines where N={grave over (P)}×N′. Each block receives in parallel one of the P′ data signals which is demultiplexed on the N′ lines of the said block. The scanning of the N′ data lines of a block is carried out from 1 to N′ or from N′ to 1, alternately, according to the selection lines.
