A plasma display apparatus and method of driving the plasma display apparatus are described. The plasma display apparatus has a plasma display panel that has a first electrode, a second electrode, and a third electrode. The plasma display apparatus also includes a first driver, a second driver and a third driver. The first driver supplies to the first electrode a first signal that decreases gradually from a first voltage to a second voltage during a setdown period of a reset period. The third driver supplies to the third electrode a third signal that increases from a third voltage to a fourth voltage during the setdown period of the reset period.

Plasma display apparatus and method of driving

In a plasma display apparatus and a method of driving the same which is driven by a driving signal having a reset period, an address period and a sustain period, a sustain pulse is applied during the sustain period, the sustain pulse including: an interval in which the sustain pulse rises from a ground voltage to a first voltage; an interval in which the first voltage is substantially constant for predetermined period of time; an interval in which the sustain pulse rises from the first voltage to a second voltage; and an interval in which the second voltage is substantially constant for a predetermined period of time. At least two discharges can be generated per a single sustain pulse by applying a sustain pulse rising and falling in two stages during one sustain period, and discharge efficiency and luminance can be improved by lengthening a light emission time by maintaining the light generated by a discharge for a predetermined time.

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, in which an afterimage erroneous discharge generated when the apparatus is driven can be prevented and damage to driving circuits can be prevented. The plasma display apparatus of the present invention comprises a plasma display panel in which a plurality of sustain electrode pairs comprising scan electrodes and sustain electrodes is formed, a driver for driving the sustain electrode pairs, and a driving pulse controller that controls the driver to sequentially apply first and second falling waveforms to the scan electrodes during a reset period, and controls the driver to apply a positive waveform whose voltage level is less than the voltage level of a sustain waveform to the sustain electrodes while the first falling waveform is applied. According to the present invention, an afterimage erroneous discharge can be prevented. Spots in an implemented monochromatic pattern can be improved. A distortion phenomenon of a display screen can be prevented. Hardware load cam be reduced by reducing EMI generating when a plasma display apparatus is driven. In addition, a complementary afterimage of implemented images can be prevented.
