A method of driving a plasma display apparatus is provided. The method of driving the plasma display apparatus includes applying a first pulse to a first electrode, applying a second pulse to a second electrode after the application of the first pulse, and applying a falling ramp pulse to the first electrode after the application of the second pulse.

Method of driving plasma display apparatus with overlapping reset pulses and a second ramp-down pulse

The present invention relates to a plasma display apparatus, and more particularly, to a driving method thereof. The plasma display apparatus includes a panel comprised of a first substrate and a second substrate bonded to each other, a first electrode and a second electrode formed on the upper substrate, and a sustain driver for applying sustain pulses to the first and second electrodes, wherein the sustain driver applies a sustain voltage between the first and second electrodes, and floats at least one of the first and second electrodes after the completion of a sustain discharge caused by the sustain voltage. In the plasma display apparatus and the driving method thereof, according to the present invention, at least one of a scan electrode and a sustain electrode is floated for a predetermined time after the completion of the sustain discharge. This floating state prevents wall charges that are generated during the sustain discharge from being accumulated and increases a discharge path of a plasma display apparatus using a space voltage, thereby improving afterimage characteristic and enhancing brightness and discharge efficiency.

Plasma display apparatus and driving method thereof

Disclosed are a plasma display apparatus and a driving method thereof. The plasma display apparatus includes a plasma display panel having a plurality of address electrodes, a data driver, and a timing controller. The data driver supplies a plurality of data pulses to the plurality of the address electrodes and the timing controller controls a width of a first data pulse of the plurality of data pulses to be different from a width of a second data pulse of the plurality of data pulse.

Plasma display apparatus and method of driving thereof

The present invention relates to a plasma display panel, in particular to a plasma display apparatus and driving method of same, wherein the bightness of sustain light generated by a sustain pulse by performing floating either a scan electrode or a sustain electrode during a sustain period, thereby increasing the driving efficiency of the plasma display apparatus. A plasma display apparatus according to an aspect of the present invention comprises a plasma display panel comprising a first electrode and a second electrode; and a controller for applying an auxiliary discharge pulse to the second electrode, when a sustain pulse is applied to the first electrode, during a sustain period.

Plasma display apparatus and driving method of the same

The present invention relates to a plasma display apparatus, and more particularly, to a plasma display apparatus and driving method thereof, wherein a sustain waveform can be improved. According to the present invention, the plasma display apparatus includes a plasma display panel comprising a plurality of sustain electrode pairs wherein each of the sustain electrode pairs has a scan electrode and a sustain electrode, and a sustain waveform controller for controlling a rising time or a falling time of sustain waveforms supplied to at least one of the sustain electrode pairs according to a temperature of the plasma display panel. The sustain waveform controller controls a time corresponding to a time point at which a sustain discharge is generated, of the rising time and the falling time. The present invention improves a plasma display apparatus and driving method thereof. Accordingly, there is an effect in that erroneous discharge depending on a temperature of a plasma display panel can be prevented.

The present invention relates to a plasma display panel, and more particularly, to a plasma display apparatus and driving method thereof, in which power consumption can be reduced and contrast can be improved, so that a high contrast image can be displayed. The plasma display apparatus according to the present invention comprises a scan electrode, a sustain electrode, and a controller for applying a rising waveform and a falling waveform to the scan electrode in a reset period of a first subfield of a frame and applying the falling waveform to the scan electrode when a first time elapses, after a first sustain voltage is applied to the scan electrode during a sustain period. The sustain electrode is applied with a second sustain voltage when a second time is elapsed, after the first sustain voltage is applied.

A method of driving a plasma display device having a plurality of scan electrode lines divided into the m (m is an integer greater than 2) number of groups, includes: applying p (p is a natural number greater than 1) number of first reset pulse having a first voltage to the scan electrode lines included in more than one group among the m number of groups during a specific frame; and simultaneously applying q (q is a natural number greater than 1) number of second reset pulse having a second voltage different from the first voltage to the second electrode line included in the rest groups except for the more than one group during the specific frame.
