Abstract:
1. A plasma display apparatus comprising: a plasma display panel configured to include a scan electrode, a sustain electrode, and a data electrode; a scan driver configured to supply, during a first subfield: a pre-reset signal which falls from a ground-level voltage (GND) to a negative sustain voltage (−Vs) to the scan electrode, a first reset signal to the scan electrode after the pre-reset signal, a scan signal which falls from the ground-level voltage (GND) to the negative sustain voltage (−Vs) to the scan electrode after the first reset signal, and a sustain signal which rises from the ground-level voltage (GND) to the positive sustain voltage (Vs) to the scan electrode after the scan signal; and a sustain driver configured to supply, during the first subfield: a first signal which rises from the ground-level voltage (GND) to the positive sustain voltage (Vs) to the sustain electrode, a sustain bias signal which rises from the ground-level voltage (GND) to the positive sustain voltage (Vs) to the sustain electrode after the first signal, and the sustain signal which rises from the ground-level voltage (GND) to the positive sustain voltage (Vs) to the sustain electrode after the sustain bias signal, wherein the scan driver is further configured to supply, during a second subfield after the first subfield: a second reset signal to the scan electrode, the scan signal which falls from the ground-level voltage (GND) to the negative sustain voltage (−Vs) to the scan electrode after the second reset signal, and the sustain signal which rises from the ground-level voltage (GND) to the positive sustain voltage (Vs) to the scan electrode after the scan signal, wherein the sustain driver is further configured to supply, during the second subfield: the sustain bias signal which rises from the ground-level voltage (GND) to the positive sustain voltage (Vs) to the sustain electrode, and the sustain signal which rises from the ground-level voltage (GND) to the positive sustain voltage (Vs) to the sustain electrode after the sustain bias signal, wherein the first reset signal includes: a first setup signal which rises from the ground-level voltage (GND) to the positive sustain voltage (Vs), a second setup signal which rises from the sustain voltage (Vs) to a voltage that is twice a magnitude of the positive sustain voltage (2Vs), and a first set-down signal which falls from the sustain voltage (Vs) to the negative sustain voltage (−Vs), wherein the second reset signal includes: a setup signal which rises from the ground-level voltage (GND) to the positive sustain voltage (Vs), and a second set-down signal which falls from the ground level voltage (GND) to the negative sustain voltage (−Vs), wherein the sustain driver is configured to supply the first signal at a time that at least partially overlaps a time at which the scan driver is configured to supply the pre-reset signal, and wherein, during the first subfield, the sustain driver is configured to supply the sustain bias signal at a time that at least partially overlaps a time at which the scan driver is configured to supply the scan signal and the first set-down signal, and, during the second subfield, the sustain driver is configured to supply the sustain bias signal at a time that at least partially overlaps a time at which the scan driver is configured to supply the second set-down signal.
