Abstract

A plasma display apparatus using a drive circuit. The drive circuit includes: first and second P-channel MOS transistors connected with a first voltage; a first N-channel MOS transistor connected between the first P-channel MOS transistor and a ground voltage, and having a gate connected with a first node and configured to receive a first input signal; and a second N-channel MOS transistor connected between the second P-channel MOS transistor and the ground voltage and having a gate connected with a second node and configured to receive a second input signal. An output P-channel MOS transistor is connected between the first voltage and an output node and has a gate connected with the second node, and an output N-channel MOS transistor is connected between the output node and the second voltage and has a gate supplied with an input signal having a same polarity as that of the first input signal. A P-channel MOS transistor has a source connected with the first node, a drain connected with the output node, and a gate connected with the second node.

Description

technical field [0001] The present invention relates to a drive circuit that performs on / off control of a high breakdown voltage P-channel FET (Field Effect Transistor). Background technique [0002] figure 1 The configuration of a conventional drive circuit shown in Patent Document 1 (Japanese Patent Laid-Open (JP 2006-101490A)) is shown. The first and second power sources NVDDH and NVDDL are connected to the driving circuit to provide a first voltage VDDH and a second voltage VDDL lower than the first voltage VDDH, and a ground voltage GND is also connected to the driving circuit. [0003] A conventional driving circuit is provided with a low voltage control part 113 , a level shift part 111 and a buffer part 112 . [0004] The low voltage control part 113 is connected between the second voltage NVDDL and the ground voltage GND. The low voltage control part 113 uses the third voltage VDDL as a power supply voltage. [0005] The level shift section 111 is provided with ...
