— The characteristics of the MgO layer are known to be an important parameter that affects the permanent image sticking or lifetime of an ACPDP. In this paper, to reduce the permanent image sticking in ACPDPs, the effects of RF‐plasma pretreatments of the MgO layer on the permanent image sticking are investigated. The treatment was conducted by using several plasma‐forming gases, including Ar, Ar followed by O 2 , and O 2 followed by Ar. Measurements of luminance, normalized luminance, V t closed curve, haze, MgO hardness, and photoluminescence between the discharge and nondis‐charge regions under dark and bright backgrounds indicated that the plasma treatments of MgO using either Ar or Ar followed by O 2 gases reduce the permanent image sticking on dark and bright images in an ACPDP.
