Abstract
Disclosed is a plasma display apparatus and a method of driving the same. The plasma display apparatus and method of driving the same, in which a plasma display panel displays images by constituting a plurality of sub-fields including a reset period in one frame, are characterized in that: gray levels are controlled by applying a sustain voltage supplied during the sustain period of a specific one of the sub-fields at a different time than the sustain voltage supplied during the sustain period of the other sub-fields.
Claims19
A plasma display apparatus, in which each of a plurality of sub-fields is divided into a reset period, an address period and a sustain period to display an image of one frame, is characterized in that:
- gray levels are controlled by applying a sustain voltage supplied during the sustain period of a specific one of the sub-fields at a different time than the sustain voltage supplied during the sustain period of the other sub-fields.
A plasma display apparatus, in which each of a plurality of sub-fields is divided into a reset period, an address period and a sustain period to express images of one frame, is characterized in that:
- when a sustain pulse is supplied to a plasma display panel during the sustain period by using an energy recovery equipment, gray levels are controlled by controlling a time difference between a turn-on timing of a first switch connected to a source capacitor and a turn-on timing of a second switch connected to a sustain voltage source of the energy recovery equipment.
