Y DRIVING CIRCUIT

摘要

A Y driving circuit for driving plasma display includes a negative descent ramp scanning voltage generating circuit, which is set between the terminals Yout and YG of the Y driving circuit. During an addressing period, the negative descent ramp scanning voltage generating circuit generates a negative descent ramp scanning voltage (VYg=-(Vy+?Vy)) on the basis of the negative voltage -Vy. The negative descent ramp scanning voltage applied to the Y electrodes descends as the addressing period extends.
