ACTUATING DEVICE FOR PLASMA DISPLAY PANEL

摘要

PROBLEM TO BE SOLVED: To provide a actuating device for a plasma display panel for shortening the unnecessary time of a reset section to the utmost. SOLUTION: The actuating device is provided with: a transistor M 5 of which the drain is electrically connected between one terminal and a grounding terminal of a panel capacitor Cp; a capacitor C 2 connected at its one terminal to the gate of the transistor M; a resistor R 1 connected in series between the other terminal of the capacitor C 2 and the drain of the transistor M 5; a diode D 2 connected in series between the other terminal of the capacitor C 2 and the drain of the transistor M 5; and a Zener diode D 3 connected in parallel to the diode D 2 and the resistor R 1. The voltage charged to the capacitor C 2 is thereby adjusted with the Zener diode D 3 and the initial voltage in a Y ramp fall section is lowered down to the voltage at which discharge occurs.
