Influence of Dielectric Layer Properties on Discharge Efficiency of ACC-Plasma Display Panel: An Experimental Study

Herein, we reported the optimization of ACC-plasma display panel.The effect of the relative permittivity (ε_r) and thickness (d) of the dielectric layer on the discharge properties, including the firing voltage, static margin, luminous efficacy and vacuum ultra-violet (VUV) emission was investigated with the lab-built test platform equipped with intensified charge coupled device video camera and spectrometer.The results show that the ε_r/d ratio of the dielectric layer had a major impact.To be specific, as the ε_r/d ratio increased, the electric field and electron temperature in cathode region increased; and the intensity of VUV emission from the discharge-produced excimers sharply increased, resulting in a significant increase of the luminous efficacy, in spite of the increasing energy loss in the discharge.
