Abstract
A plasma discharge method and a plasma display using the same. In the method, a sustain discharge uses a facing surfaces discharge and a surface discharge after an address discharge. The discharges occur in separate discharge areas, and priming particles generated by the discharges are exchanged. Thus, the stability and the efficiency of the sustain discharge increase, and a gap for the address discharge decreases to lower a breakdown voltage.
Claims24
A plasma discharge method, comprising:
- providing a first plate and a second plate with a discharge gas in an area in between;
- generating an address discharge by using a plurality of first and second sustain electrodes arranged in the first plate and a plurality of address electrodes arranged in the second plate and corresponding to the first and second sustain electrodes;
- generating a first sustain discharge in auxiliary discharge wells in the first plate by using a plurality of first and second bus electrodes, the first and the second bus electrodes extending deep into the first plate and forming surfaces that face each other;
- and
- generating a second sustain discharge by the first and second sustain electrodes that are arranged in the first plate and respectively electrically connected to the first and second bus electrodes, with the first sustain discharge maintained.
