In a Positive Column AC PDP (L.F. Weber patent N° U66184848B1) the discharge is more efficient than in standard AC PDP, because of the large coplanar electrode gap. The discharge between coplanar electrodes (large breakdown voltage) is initiated by a first discharge between one of the coplanar electrodes, and the address electrode. |

Simulation of a Positive Column AC PDP using SIPDP-3D |
The simulation shows that the main discharge between the coplanar electrodes is initiated by a discharge between one of the coplanar electrodes and the address electrodes. The current of this matrix discharge must be minimized, for example by using a larger dielectric thickness on the address electrode side.
The simulation also shows that about 40% of the discharge energy is dissipated in xenon excitation. This is 2 times larger than in a standard configuration. The operating voltage is significantly larger than in the standard case (250 V sustaining pulses).
The results are similar to those (below) obtained with the 2D SIPDP-AC simulator, but the 3D code allows to better describe the role of the address electrode
