Abstract
A plasma display panel includes a front substrate having a first edge and a second edge in opposition to each other, a signal transmitter positioned at the first edge of the front substrate, a signal receiver disposed on the second edge of the front substrate, a detecting wire disposed on the front substrate, and a control circuit coupled to the signal transmitter and the signal receiver. The detecting wire has a first end and a second end, the first end is coupled to the signal transmitter, and the second end is coupled to the signal receiver. When a detecting signal is transmitted by the signal transmitter and is not received by the signal receiver, the control circuit interrupts the bias applied between a plurality of sustaining electrodes and a plurality of scanning electrodes.

A plasma display panel having a plurality of pixels, a plurality of sustaining electrodes, and a plurality of scanning electrodes, a discharge operation being performed in the plurality of pixels when a bias being applied between the plurality of sustaining electrodes and the plurality of scanning electrodes, said plasma display panel comprising:
- a front substrate having a first edge and a second edge in opposition to each other;
- a scan driver disposed on the first edge of said front substrate;
- a signal receiver disposed on the second edge of said front substrate;
- a detecting wire formed on the front substrate, said detecting wire having a first end and a second end, the first end being coupled to said scan driver, and the second end being coupled to the signal receiver;
- and
- a control circuit coupled to said scan driver and said signal receiver,
- wherein when a scan driving signal is delivered by said scan driver and is not received by said signal receiver, said control circuit interrupts the bias applied between the plurality of sustaining electrodes and the plurality of scanning electrodes so as to stop the discharge operation in the plurality of pixels.
