Abstract

The present invention provides a method of driving a plasma display device through a plurality of subfields divided from a frame when different driving waveforms are applied during reset periods of the plurality of subfields. During the address period, by adjusting the bias voltage applied to the sustain electrode according to the driving waveform of the previous reset period, it is possible to prevent defective addressing that may be caused by the unstable wall charge state remaining at the end of the reset period operate.

Description

technical field [0001] The present invention relates to a plasma display device, and more particularly, to a driving method for stably generating address discharge. Background technique [0002] A plasma display device is a flat panel display device that displays characters and images using plasma generated by a gas discharge process. It includes a Plasma Display Panel (PDP) with tens of millions of pixels provided in a matrix in accordance with the size of the PDP. [0003] According to a typical driving method of a PDP, each frame is divided into a plurality of subfields, and a displayed image is represented by a combination of subfields. Each subfield has a reset period, an address period, and a sustain period. In the reset period, the wall charges formed by the previous sustain discharge are erased, and the wall charges are established so that the following addressing can be stably performed. The address period is for selecting on / off discharge cells (ie, discharge ce...
