Characterization of PDP performance prepared by vacuum in‐line sealing technology

Abstract By using vacuum in‐line driving and photoluminescence measuring system, we have examined the electrical and optical characteristics of plasma display panel produced by vacuum in‐line sealing technology. In addition, the relationship between luminous efficiency and base vacuum level before filling discharge gas was analyzed. In the case of base vacuum level of 1.33 × 10‐1 Pa, the firing voltage of a 2‐inch diagonal PDP panel was ranged from 312 to 343 V depending on the discharge gas pressure of 2.667 × 104 to 4×104 Pa at room temperature, Whereas in the case of 1.33×10‐4 Pa, the firing voltage was reduced by 40 V and luminescence was improved slightly.
