  • Samsung's newly developed high luminance efficiency 42" VGA plasma display panel is introduced. A new discharge cell structure, SDR (Segmented electrode in Delta color arrayed Rectangular subpixel) has been applied to a full size panel for the first time. In this paper, we describe how this new discharge cell structure for high efficiency is integrated to an energy saving plasma display with better picture quality.

  • A microwave plasma generating system has been designed to study the properties of plasma. A microwave(2.45GHz) generated by the magnetron is transmitted to the cylindrical cavity through the the rectangular wave guide to generate hydrogen plasma. The electron temperature and the plasma density are measured by the Double Langmuir probe. A dilectric such as alumina is heated by the microwave add plasma. The surface temperature varies with the neutral gas pressure.
