METHOD FOR COMPENSATING A PERTURBED CAPACITIVE CIRCUIT AND APPLICATION TO MATRIX DISPLAY DEVICE

摘要

The invention concerns a method for compensating a circuit comprising a first conductor (lj) with specific potential, at least a second conductor (ci) generating perturbations on the first conductor by capacitive coupling, a first bus (CE) at a reference voltage in capacitive coupling with the first conductor. The method comprises the following steps: measuring the current flowing on the first bus (CE) when a voltage is applied on the second conductor; integrating a measured current so as to obtain a compensating voltage to be applied on the first conductor. The invention is applicable to AM-LCD type liquid crystal display screens.
