Problems solved by technology

[0017] However, the general positioning voltage (Va) is determined by the positioning margin (margin) and the withstand voltage of the positioning drive IC (not shown) that performs the positioning work. Generally, it is about 50~60V. Therefore, it will be as follows Figure 3c When the plasma driving device shown is applied to an actual PDP, if the positioning voltage margin is not sufficiently ensured, the positioning discharge will be unstable, which will adversely affect the performance and reliability of products including plasma display panels. influences

Abstract

An apparatus and a method for driving a PDP are provided to reduce manufacturing cost of the PDP by integrating a sustain voltage source for generating a voltage for sustain discharge with an address voltage source for generating an address pulse voltage. An apparatus for driving a PDP(Plasma Display Panel) includes a source voltage supply unit(41) and a boosting circuit(45). The source voltage supply unit supplies a first voltage(Vs / 4) to scan and sustain electrode drivers so as to supply a voltage required for sustain discharge of the PDP. The boosting circuit supplies a second voltage having a voltage different from the first voltage to an address electrode driver using the first voltage from the source voltage supply unit in order to supply an address pulse type voltage to the PDP.

Description

1. Technical field [0001] The present invention relates to a driving device and a driving method of a plasma display panel. More specifically, it is a power supply for generating a voltage waveform required for sustaining discharge and a power supply for generating a positioning pulse voltage waveform, thereby enabling A driving device and a driving method of a plasma display panel which solve the positioning voltage margin problem in a simple way. 2. Background technology [0002] Plasma Display Panel (Plasma Display Panel: hereinafter referred to as 'PDP') is a display device that utilizes the phenomenon that visible light is generated when phosphors are excited by ultraviolet rays generated by gas discharge. Compared with a cathode ray tube (CRT), the PDP has the advantage of being thinner and lighter, and capable of displaying a high-definition large screen. A general PDP is composed of a plurality of discharge cells (cells) arranged in a matrix form, and one discharge ...
