Abstract: The present invention relates to a process for compensating a circuit comprising at least one first conductor (lj) with a specified potential, at least one second conductor (ci) generating disturbances on the first conductor by capacitive coupling, and a first bus (CE) with a reference voltage, coupled capacitively to the first conductor. The process comprises the following steps: measurement of the current flowing on the first bus (CE) upon the application of a voltage to the second conductor, integration of a measured current so as to obtain a compensation voltage to be applied to the first conductor. Applications to liquid crystal screens of the AM-LCD type.
