PURPOSE: A Y-driver for plasma display panel is provided to simplify a structure and reduce manufacturing costs by excluding a switching device to switch the large amount of current between a Y-electrode and an energy recovery circuit. CONSTITUTION: A Y-driver for plasma display panel includes the first switch(Ys), an integral circuit, the second switch(Ys1), and the third switch(Yrr). The first switch(Ys) is used for switching a scan voltage. The integral circuit is serially connected between the reset voltage and the first switch(Ys) in order to form a rising period of a ramp pulse in a reset period. The second switch(Ys1) is inserted between a contact point between the first switch(Ys) and the integral circuit and a Y-electrode. The third switch(Yrr) is inserted between an output terminal for an integral voltage of the integral circuit and the Y-electrode. The first switch(Ys) is turned on in the rising period of the ramp pulse and turned off in a falling period of the ramp pulse. The second switch(Ys1) and the third switch(Yrr) is turned off in the rising period of the ramp pulse and turned on in the falling period of the ramp pulse. |
