Abstract
The present invention relates to a plasma display apparatus and a driving method thereof. According to embodiments of the present invention, the plasma display apparatus and the driving method thereof apply a driving pulse and a driving erasing voltage to an electrode when power supply is blocked. The driving pulse and the driving erasing voltage have opposite polarities. On the basis of the embodiments of the present invention, an excessive state of an image quality, which often appears after power supply is blocked can be impaired, and a stable operation of the plasma display apparatus can be implemented.
Claims19
A plasma display apparatus comprising:
- a power blocking detection unit for detecting whether power supply is blocked and outputting a detection signal thereafter;
- a controller for outputting a control signal according to the detection signal;
- an electrode driver for supplying a driving erasing voltage having a polarity reverse to the polarity of a driving pulse according to the control signal;
- and
- a plasma display panel comprising an electrode and applied with the driving erasing voltage through the electrode.
A driving method of a plasma display apparatus comprising an electrode, the driving method comprising:
- determining whether power supply is blocked;
- outputting a detection signal when the power supply is blocked;
- outputting a control signal according to the detection signal;
- and
- applying a driving erasing voltage erasing a driving pulse according to the control signal.
