Abstract
A plasma display panel apparatus and a method of driving the same are disclosed. Right after power is supplied to a panel, driving waveforms are applied such that an address discharge and a sustain discharge cannot occur during at least one or more sub-fields. Accordingly, time for a source capacitor of an energy recovery unit provided in a scan driver and a sustain driver to be charged with a voltage can be secured and a preliminary time for an element of the driving circuit and the discharge cell to be activated can be secured, to thereby prevent damage of the element.

A method of driving a plasma display panel in which the driving is performed by time division of one frame into at least one or more sub-fields, wherein after power is supplied to the panel, at least one or more sub-fields comprise a sustain period during which a first waveform is applied to one of a scan electrode and a sustain electrode and a second waveform different from the first waveform is applied to the other electrode, without having an address period.
A method of driving a plasma display panel in which the driving is performed by time division of one frame into at least one or more sub-fields, wherein right after power is supplied to the panel, all the sub-fields of at least one or more frames comprise a reset period during which a reset waveform for initializing a cell is applied and a sustain period during which a first waveform is applied to one of a scan electrode and a sustain electrode and a second waveform is applied to the other electrode without having an address period after the reset period.
A plasma display panel apparatus comprising:
- a panel comprised of at least one or more electrodes;
- and
- a sustain driver and a scan driver for driving a sustain electrode and a scan electrode, respectively,
- wherein after power is supplied to the panel, the scan driver applies a first waveform during a sustain period following a reset period during at least one or more frames, and the sustain driver applies a second waveform different from the first waveform during the sustain period.
