Abstract

The present invention relates to a drive device and method of a plasma display panel in which the manufacturing cost of a PDP can be reduced. The plasma display panel in accordance with the present invention has a drive device comprising: a IC circuit supplying drive voltage to scan electrodes; a energy recovery circuit supplying sustain voltage to the IC circuit; a set up supply part supplying rising ramp wave form to the IC circuit during set up period; and a set down supply part supplying falling ramp wave form to the IC circuit during set down period, wherein said drive device includes a switch which connects the set up supply part to the set down supply part and is turned on or off responding to voltage supplied to the IC drive circuit during the set down period.

Description

[0001] This non-provisional application claims priority under 35 U.S.C. §119(a) to Patent Application No. 10-2003-0021630 filed in Korea on April 7, 2003, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to a driving device and method of a plasma display panel (hereinafter referred to as "PDP"). More particularly, the present invention relates to a driving device and method of a PDP that can reduce the manufacturing cost of the PDP. [0003] Also, the present invention relates to a PDP, and more particularly, to a driving method of a PDP that can reduce power consumption. Background technique [0004] When He+Xe, Ne+Xe, He+Ne+Xe and other inert mixed gases are discharged, 147nm ultraviolet rays will be generated, and the ultraviolet rays will excite fluorescent substances, so the plasma display panel (hereinafter referred to as "PDP") displays characters including or graphic images. It is easy to make...
