Abstract
Ion-induced secondary electron emission from the MgO protecting layer of an AC plasma display panel (AC-PDP) and the successive back-scattering of secondary electrons toward the cathode due to high gas pressure have been studied theoretically. A correlation between the intrinsic secondary electron emission coefficient (γi) and the MgO surface properties such as band gap energy and defect states in the band gap was found. The behavior of the effective secondary electron emission coefficient (γeff) of various ion species as a function of the reduced electric field (E/P) has also been investigated. These relationships can be applied to AC-PDP manufacturing in order to enhance the luminous efficiency and to reduce the breakdown voltage of AC-PDPs.Keywords
