Embodiment Construction

[0035] Reference will now be made to the appended drawings which illustrate exemplary embodiments of the invention. picture The present invention will be described.

[0036] figure 1 A configuration of two electrodes of a plasma display panel (PDP) according to an embodiment of the present invention is shown.

[0037] see figure 1 , a plurality of address electrodes A1 to Am are arranged from the top of the PDP to the bottom of the PDP, and a plurality of scan electrodes Y1 to Yn are arranged to cross the plurality of address electrodes A1 to Am. The discharge cells Ce are divided in regions where the plurality of address electrodes A1 to Am and the plurality of scan electrodes Y1 to Yn cross each other. displayed by the discharge generated in the discharge cell Ce picture picture.

[0038] figure 2 Perspective picture shows the figure 1 PDP with the electrode configuration shown, image 3 yes figure 2 Partial exploded perspective view of addressing and scanning...

Abstract

An apparatus to drive a Plasma Display Panel (PDP) reduces heat by preventing a current generated by a sustain discharge from affecting a drive circuit. The apparatus is to drive a PDP including discharge cells and at least first and second electrodes. The apparatus includes: a display data signal supplier adapted to supply a display data signal to the second electrodes during an address period where a discharge cell of the discharge cells in which the discharge is to occur has been selected; and a switching unit adapted to switch to prevent a current generated by a sustain pulse supplied to the first electrodes from flowing through the display data signal supplier during a sustain period where the discharge occurs in the selected discharge cell.

Description

technical field [0001] The present invention relates to an apparatus for driving a plasma display panel (PDP), and more particularly, to an apparatus for driving a PDP in which heat generation is reduced by preventing current generated by sustain discharge from affecting a driving circuit. Background technique [0002] A plasma display panel (PDP) is a wide-screen flat panel display used to stimulate the formation of picture like phosphors and produce visible light to display the desired picture picture. [0003] A device for driving a PDP supplies a driving signal to a plurality of electrodes. In order to induce discharge in discharge cells divided by intersecting the plurality of electrodes, discharge cells affecting discharge are first selected and sustain discharge is reduced in the selected discharge cells. Current generated by the sustain discharge flows through electrodes in the device to drive the PDP, and generates heat in a driving circuit of the device for driv...
