Chang-Wook Han, Sung-Suk Wi, Don-Kyu Lee · The Transactions of The Korean Institute of Electrical Engineers · 2015
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 %.
