Abstract

A plasma display apparatus and a method of driving the same are disclosed. A scan driver of the plasma display apparatus supplies scan signals to scan electrodes using a first scan type in a first subfield of a frame, and supplies the scan signals to the scan electrodes using a second scan type, which supplies the scan signals in an order different from the first scan type, in a second subfield of the frame. The scan electrode or a sustain electrode includes a base formed in a direction of the scan electrode and the sustain electrode and a projecting portion. The projecting portion projects from the base toward a central direction of a discharge cell.

Description

technical field [0001] The present invention relates to a display device, and more particularly, to a plasma display device and a driving method thereof. Background technique [0002] A plasma display panel includes a front panel, a rear panel, and barrier bars formed between the front panel and the rear panel. The barrier ribs form a unit discharge cell or a plurality of discharge cells. Each discharge cell is filled with a main discharge gas including, for example, neon (Ne), helium (He), and a mixture of Ne and He, and an inert gas of a small amount of xenon (Xe). When discharged by a high-frequency voltage, the inert gas generates vacuum ultraviolet rays, thereby causing fluorescent materials formed in the discharge cells to emit light, thereby displaying images. Since the plasma display panel can be manufactured thin and light, it has drawn attention as a next generation display device. [0003] A plurality of electrodes such as scan electrodes, sustain electrodes an...
