发明名称 Method for compensating distortions in a capacitive circuit and its use in matrix displays
摘要 <p>The procedure enables capacitive coupling compensation to be applied to a circuit with a primary conductor held at a first given potential, and a secondary conductor generating perturbations by capacitive coupling with the primary. A compensation bus (e, e') provides compensation for the capacitively coupled perturbations on the first conductor by a capacitance C1, where C1 = (Cej + Ce'j). The procedure involves measuring the voltage (Vcomp) and the current (Icomp) on the compensation bus, and calculating the voltage (Vpert) on the first perturbed conductor. A calculation is then made to determine the reference voltage to be applied to the compensation bus in order to compensate for the perturbation.</p>
