The breakdown characteristic of a new PDP discharge cell is investigated.This novel structure of PDP has many advantages

such as low discharging voltage

high response frequency

high brightness and low cost etc..The comparison with conventional coplanar PDP has been made.The electric field distribution and the density distribution of particles at different time have been given.The variation of average density of particles has also been calculated.The luminance efficiency of 14″ experimental panel with the novel structure is 0.9lm/W and the power consumption is 50W without energy recovery circuit.
