US Patent 7872616 Plasma display apparatus and driving method thereof

There is provided a plasma display apparatus and a driving method thereof, and more particularly, to a plasma display apparatus which drives an electrodes and a driving method thereof. The plasma display apparatus includes a plasma display panel including an electrodes; a first voltage supply unit supplying a first voltage to the electrodes at a setup period; and a setup/scan operation unit supplying a ramp-up pulse to the electrodes at the setup period with one voltage source and supplying a second voltage to the electrodes at an address period with the one voltage source. The driving apparatus of a plasma display panel includes a plasma display panel including an electrodes; a first voltage supply unit supplying a first voltage; a first setup supply unit supplying a first ramp-up pulse rising from the first voltage to a first sum voltage corresponding to a sum of the first voltage and the second voltage to the electrodes; and a second setup supply unit supplying a second ramp-up pulse rising to a second sum voltage corresponding to a sum of the first voltage, the second voltage, and the third voltage to the electrodes after the first ramp-up pulse is applied and a second setup supply unit supplying the third voltage to the electrodes when scanning the electrodes. Therefore, it is possible to reduce the production cost by decreasing the number of components and improve a driving efficiency by raising a voltage of a setup waveform at a reset period.
