Abstract

A plasma display apparatus comprises a plasma display panel that comprises an electrode; a sustain driver that supplies a sustain signal to the electrode and that comprises a first and second switching elements for supplying the sustain signal; and a first and second gate drivers that drives each of the first and second switching elements, wherein the first gate driver receives a driving voltage for driving the first switching element from a driving voltage source of the first gate driver, the second gate driver comprises a driving voltage source that supplies a driving voltage for driving the second switching element, and an auxiliary voltage for assisting the driving voltage is supplied from the outside of the second gate driver so that the second switching element is driven by the driving voltage. Arranging the voltage to change in steps avoids the need for switching devices to handle the full amplitude of the sustain pulse, allowing switches of a lower voltage rating to be employed.

Description

technical field [0001] The present invention relates to plasma display devices. Background technique [0002] Generally, in a plasma display device, a plasma display panel displaying an image and a driver driving the plasma display panel are attached to a rear surface of the plasma display panel. [0003] The plasma display panel includes a plurality of discharge cells formed using barrier ribs between a front substrate and a rear substrate of the plasma display panel displaying images. Each cell is filled with a main discharge gas including, for example, neon (Ne), helium (He), or a mixed gas of Ne+He and an inert gas of a small amount of xenon (Xe). Multiple cells form a pixel. For example, a red (R) discharge cell, a green (G) discharge cell, and a blue (B) discharge cell form one pixel. [0004] The driver provides driving signals for driving the plasma display panel with various functions. [0005] A sustain driver among the drivers supplies a high voltage of a sust...
