Plasma display apparatus and driving method thereof

摘要

A plasma display apparatus comprises a plasma display panel comprising an electrode and an energy recovery/supply unit comprising a variable inductor located in the supply path of a pulse applied to the electrode. A driving method of a plasma display apparatus comprises the steps of varying the inductance of the inductor in charging/discharging paths according to the screen pattern or load of a plasma display panel and making a rising/falling slope of the sustain pulse constant. Adjusting the inductance in response to the screen pattern or load can prevent variations in the displayed image and enhance operating efficiency. Providing the respective supply and recovery paths with different values of inductance can allow the panel capacitance to be charged faster than it is discharged.
