Abstract

A plasma display apparatus and a method of driving the same are disclosed. In the plasma display apparatus, a scan driver supplies scan signals to a plurality of scan electrodes using a first scan type in a first subfield of a frame, and supplies the scan signals to the plurality of scan electrodes using a second scan type, which directs the scan driver to supply the scan signals in an order different from the first scan type, in a second subfield of the frame. Further, the scan driver consecutively supplies a first scan signal and a second scan signal to a first scan electrode and a second scan electrode of the plurality of scan electrodes. A supply end time point of the first scan signal is later than a supply start time point of the second scan signal.

Description

technical field [0001] The present invention relates 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 and data electrodes are formed in the plasma d...
