Enhancement of Discharge Characteristics Using RF-Plasma Treatment on MgO Layer In 50-in. Full-HD AC-PDPs

摘要

The characteristics of the MgO layer are known to be an important parameter that affects both the address and sustain discharge characteristics in an ac-PDP. In this paper, to improve the discharge characteristics of 50-in. full-HD ac-PDP with He (35%) - Xe (11%) contents, RF-plasma treatments on the MgO layer are examined under various gases for plasma treatment. The resulting changes in the address and sustain discharge characteristics, including the firing voltage, Vt closed curve, power consumption, luminance, luminous efficiency, and secondary electron coefficient, are then compared for both cases with and without plasma treatment on MgO layer. It is concluded that the Ar plasma treatment can enhance the discharge characteristics, such as the firing voltage and power consumption, which are caused by an increase in the secondary electron coefficient.
