摘要： A method of driving a plasma display panel (PDP) and a plasma display device driven by the method are disclosed. In one embodiment, a display image is represented by a plurality of unit frames, and each unit frame is divided into a plurality of sub-fields. Each of the sub-fields includes a reset period when all discharge cells are initialized, an address period when a discharge cell that is turned on or off is selected from all discharge cells, and a sustain period when a sustain discharge is performed for a discharge cell selected to be turned on in the address period according to gray-level weights allocated to each of the sub-fields. Furthermore, a rising ramp pulse and a falling ramp pulse are applied to the first electrode in the reset period. According to one embodiment of the invention, reset light generated by a reset discharge can be minimized in a reset period, and wall charges in discharge cells can be precisely controlled so that light-emitting efficiency is improved and the likelihood of a permanent afterimage being left on the display is reduced.

摘要： In a method and apparatus for improving the address discharge efficiency of a plasma display panel (PDP), the PDP has a new structure which improves light-emitting efficiency and reduces a permanent afterimage. The PDP includes first and second substrates spaced apart from each other, a barrier rib which, together with the first and second substrates partitions discharge cells which are discharge spaces, first and second electrodes extending so as to cross each other in the barrier rib, a phosphor layer formed in the discharge cells, and a discharge gas in the discharge cells. In the method and apparatus, each unit frame used to express an image is divided into a plurality of sub-fields, and each of the sub-fields is divided into a reset period wherein all discharge cells are initialized, an address period wherein a discharge cell which is turned on or off is selected from all discharge cells, and a sustain period wherein a sustain discharge is performed for a discharge cell selected to be turned on in the address period according to gray-level weights allocated to each of the sub-fields. In addition, a falling pulse is applied to the first electrode in the reset period, and scan pulses are sequentially applied to the first electrode in the address period. The electric potential of a low level of the scan pulse is lower than the electric potential of a minimum level of the falling pulse.
