Patent number: 7705801Abstract: The present invention provides a driving method suitable for a plasma display. The plasma display includes multiple scan electrodes, multiple sustain electrodes and multiple address electrodes, for example. Successive frames are adapted to be displayed in repeating reset periods, address periods and sustain periods by applying driving signals to the scan electrodes, sustain electrodes and address electrodes. The driving method is characterized in that before inputting driving signals or when interrupting driving signals, a wall-charge removing signal is applied to the scan electrodes to remove/reduce the residual wall charges around the scan electrodes and the sustain electrodes. As a result, the possibility of the plasma display generating erroneously discharging with strong light at the restarting state can be effectively reduced.Type: GrantFiled: November 3, 2004Date of Patent: April 27, 2010Assignee: Chunghwa Picture Tubes, Ltd.Inventors: Chung-Lin Fu, Yu-Ting Chien, Chi-Hsiu Lin
