Patent ID: 7679583

Claim:
A driving method of a plasma display in which a field is divided into N subfields having brightness weights, and gray scales are expressed by a summation of weights of subfields from among the N subfields, wherein the plasma display includes a plurality of discharge cells, the method comprising: mapping image data on the N subfields; setting valid data corresponding to M subfields from among the N subfields; and when a first discharge cell has invalid data, setting valid data of the first discharge cell according to data of at least one discharge cell that is provided at the same address line as that of the first discharge cell and is scanned at a time that is different from that of the first discharge cell, the at least one discharge cell being a different discharge cell than the first discharge cell, wherein N and M are natural numbers greater than zero, and M is less than N, and wherein the valid data of the first discharge cell is set according to data of a second discharge cell that is scanned temporally before the first discharge cell and data of a third discharge cell that is scanned temporally after the first discharge cell.
