摘要： A method for driving a plasma display panel having front and rear substrates opposed to and facing each other, X and Y electrode lines between the front and rear substrates and parallel to each other and address electrode lines orthogonal to the X and Y electrode lines, to define corresponding pixels at intersections. In the driving method, a scan pulse is applied to the respective Y electrode lines with a time difference and the corresponding display data signals are simultaneously applied to the respective address electrode lines to form wall charges at pixels where a display discharge is to occur. Pulses for a display discharge are alternately applied to the X and Y electrode lines to cause a display discharge at the pixels where the wall charges have been formed. Also, the pulses for display discharges simultaneously applied to the X electrode lines start after the pulses for display discharges simultaneously applied to the Y electrode lines terminate, and the scan pulses and the corresponding display data signals are applied after the pulses for display discharges simultaneously applied to the X electrode lines terminate and before the pulses for display discharges simultaneously applied to the Y electrode lines start. The power levels of pulses for display discharges simultaneously applied to the Y electrode lines are greater than the power levels of pulses for display discharges simultaneously applied to the X electrode lines.

摘要： In an address-while-display (AWD) driving method in which addressing and sustaining are simultaneously performed, a plasma display panel (PDP) is driven with an automatic power control function for reducing power consumption when there are lots of ON pixels over the entire PDP, that is, the brightness of the screen of the PDP is higher than a predetermined level. In the PDP driving method, in order to suppress power consumption for maintaining a bright state of the screen, discharge sustain pulses at respective sub-fields for implementing gray scale display of each frame are invalidated using erase pulses in a constant ratio for each sub-field, while all the video signals applied in the form of the AWD driving waveforms are continuously applied to the respective frame periods in which all the video signals are displayed without interruption, that is, irrespective of whether discharge is performed. Thus, while attaining an improvement in the luminance by applying many discharge sustain pulses based on the AWD driving method, the power consumption at high luminance is automatically reduced.
