Problems solved by technology

[0046] In view of the above-mentioned problems of conventional drive circuits for driving plasma display panels, it is an object of the present invention to provide a circuit for driving plasma display panels which can solve problems due to heat between a common substrate and a scanning substrate and timing of heat generation. Problems caused by differences, prevention of electromagnetic interference due to maintaining current flow in the module board ground, prevention of circuit loss due to inductance, and prevention of generation of overshoot in the output signal waveform

Abstract

In a circuit for driving a plasma display panel including a first circuit formed on a scanning substrate for driving a scanning electrode, and a second circuit formed on a common substrate for driving a common electrode, the circuit in accordance with the present invention is characterized by including a single substrate in place of the scanning and common substrates wherein the first and second circuits are formed on the single substrate.

Description

Technical field [0001] The invention relates to a driving circuit of a plasma display panel. Background technique [0002] Compared with other types of display panels, plasma display panels have the following advantages, and therefore are widely used in large-screen outdoor display units or large-screen televisions. [0003] (a) The shape of the plasma display panel can be made thinner. [0004] (b) The plasma display panel provides greater display contrast. [0005] (c) The plasma display panel can be easily designed to have a large screen. [0006] (d) The plasma display panel has a higher response speed. [0007] (e) The plasma display panel emits light by itself, so it can emit light of multiple colors through the use of fluorescent materials. [0008] Many kinds of plasma display panels have been proposed, for example, in Japanese Patent Application Publication No. 5-290742. [0009] figure 1 It is a perspective view of a conventional plasma display panel 200. [0010] The...
