A plasma display apparatus and a driving method thereof are disclosed. The plasma display apparatus includes a plasma display panel comprising a first electrode and a second electrode, and a driver for applying a plurality of sustain signals to the second electrode while applying two consecutive sustain signals to the first electrode in a sustain period. A method of driving a plasma display apparatus includes applying a first sustain signal to a first electrode in a sustain period, after applying the first sustain signal to the first electrode, applying a plurality of sustain signals to a second electrode, and after applying the plurality of sustain signals to the second electrode, applying a second sustain signal consecutive to the first sustain signal to the first electrode.

Plasma display apparatus and driving method thereof to reduce after-images

A plasma display apparatus and a method of driving the plasma display apparatus are provided. The plasma display apparatus includes a plasma display panel including a first electrode and a second electrode, a first electrode driver, and a second electrode driver. The first electrode driver supplies a first falling signal of a voltage magnitude, that is more than a voltage magnitude of a scan signal supplied during an address period, to the first electrode before the supply of a rising signal with a gradually rising voltage in at least one subfield of several subfields of a frame. The second electrode driver supplies a second signal having a polarity opposite a polarity of the first falling signal to the second electrode during the supply of the first falling signal.

Plasma display apparatus having separated electrodes and method of driving plasma display

A plasma display apparatus and a driving method of a plasma display panel are provided. This may include a plasma display panel having a plurality of scan electrodes and sustain electrodes, and a plurality of address electrodes formed to intersect with the plurality of scan electrodes and sustain electrodes. A driving unit/circuit may drive the scan electrodes, the sustain electrodes, and the address electrodes to allow a voltage difference between the scan electrode and the sustain electrode or a voltage difference between the scan electrode and the address electrode during an address period at one or more subfields of a frame to be larger than a voltage difference between the scan electrode and the sustain electrode or a voltage difference between the scan electrode and the address electrode during the address period at other subfields.

Plasma display apparatus and driving method thereof

The present invention relates to a plasma display apparatus and a driving method thereof in which an erroneous discharge, a misdischarge and an abnormal discharge are prevented, a darkroom contrast is increased, an operation margin is widen, and an influence of a lower substrate wall charge is reduced in a sustain discharge. The plasma display apparatus and its driving method is characterized in that when the plasma display panel has a second temperature higher than a first temperature, a period between the last sustain pulse generated during a sustain period of (n&#x2212;1)sub-field ('n' is a positive integer) and an initialization signal generated during a reset period of nsub-field is more lengthened than when it has the first temperature. The plasma display apparatus and its driving method is characterized in that a pre sustain pulse (PRESUSP) rising from a sustain bias voltage (Vzb) is applied to the second electrode in the sustain period.

A plasma display apparatus is provided. The plasma display apparatus comprises an energy recovery unit and a sustain driver for applying a voltage recovered from the energy recovery unit to sustain electrodes as a bias voltage in an address period. The voltage recovered to a source capacitor is applied as the bias voltage in the address period so that it is possible to apply the bias voltage that varies in accordance with the sustain voltage of a plasma display panel without an additional external power source. As a result, it is possible to reduce the manufacturing expenses of the plasma display apparatus.
