A Study on the Discharge Characteristics of Micro Dielectric Barrier Discharge Cells by Adding TiO₂ or MgO Powder

Abstract

-For a higher definition discharge cell, the method of high speed addressing is necessary. In order to modify the surface charges, the liquefied TiO2 or MgO powder is added on MgO layer in front glass and on the phosphor in rear glass in micro barrier discharge. Both the electro-optical properties and the discharge time lag characteristics are measured from 4 inch. test panel, such as the discharge voltage, current, luminance, luminous efficacy and discharge time lag. As the results, the statistic time lag is improved by about 40 %.
