Title: Driving Method for Erasing Discharge of Plasma Display Panel and Driving Apparatus Thereof
Inventor: CHOI JEONG PIL
IPC: G09G3/296
Filed: 2001-04-11
Abstract: PURPOSE: A method for driving an erase discharge of a plasma display panel and a driving device thereof are provided to enhance efficiency of the erase discharge by applying resonant erase pulses to a scan electrode as well as a sustain electrode. CONSTITUTION: A reset pulse(RP) is applied to a scan electrode during a reset period. A voltage of the reset pulse(RP) is increased in a setup process and the voltage of the reset pulse(RP) is reduced in a set-down process. A reset discharge is generated in the setup process by the reset pulse(RP) and wall charges are generated on an upper dielectric, thereby. The wall charges are reduced in the set-down process. In order to reduce the wall charges, a DC voltage(Vs) of positive polarity is applied to a sustain electrode. The wall charges are reduced by inversion of polarity since the scan electrode has negative polarity relatively to the sustain electrode in the set-down process. A scan pulse(SP) and a data pulse(DP) are applied to the scan electrode and an address electrode during an address period, respectively. A triggering pulse is applied to the scan electrode at the beginning of a sustain period(SPD) and a sustain discharge is started in a discharge cell, thereby. The sustain discharge is maintained by applying sustain pulses(SUSPz,SUSPy) to the sustain electrode and the scan electrode. An erase pulse(EP) is applied to the sustain electrode in an erase period and the sustain discharge is stopped.
