Sustain pulse controlling method and apparatus for a plasma display apparatus

摘要

This document relates to a plasma display apparatus and driving method thereof, and more particularly, to a plasma display apparatus for driving electrodes and driving method thereof. A plasma display apparatus according to an embodiment of the present invention comprises a plasma display panel comprising a scan electrode and a sustain electrode, a driver for driving the scan electrode and the sustain electrode and a sustain pulse controller for controlling the driver so that a first sustain pulse applied to the scan electrode and a second sustain pulse applied to the sustain electrode are overlapped with each other, and for setting a rising (ER-Up) period of the first sustain pulse applied to the scan electrode and a Y sustain period where the first sustain pulse is maintained at a sustain voltage (Vs) to be different from a rising (ER-Up) period of the second sustain pulse applied to the sustain electrode and a Z sustain period where the second sustain pulse is maintained at the sustain voltage (Vs). This invention is advantageous in that it can enhance driving efficiency and improve a bright afterimage, by improving a sustain pulse of a sustain period.
