Electrical discharge as an inspection method for imperfect plasma display cells

The plasma display panel is a self-emitting gas discharge operated device. In this paper, the atmospheric pressure helium discharges were used to inspect the defects of PDP cells related to dielectric covered electrodes. Experiments were made to repair the identified imperfect discharge cells through designated optimized methods such as refilling with transparent dielectric glass to make a monolithic dielectric for flawless PDP operation.
