TW393658B - Plasma display panel with a low startup voltage and its startup method - Google Patents

Abstract

A plasma display panel with a low startup voltage is composed of two parallel panels, an ionized gas between the two panels, four electrodes on both panels, and a display control circuit electrically coupled to the four electrodes to control their operations. The first and the second electrode are parallel to the first panel; the third electrode is vertical to the first electrode and the second electrode on the second panel. The fourth electrode is parallel to the adjacent side of the first electrode. Each of the three electrodes projected to the plane area formed by the first and second electrode forms a display unit for controlling the plasma inside. The first and fourth electrodes are used to produce a start-up plasma; the first and second electrodes disperse to the entire display unit and drive the plasma back and forth to maintain the display function.
