AC plasma display controlled by applying second erasing pulse of negative polarity of moderate falling leading edge to held electrode in order to erase its accumulated positive charge

摘要

A first erasing pulse of a positive polarity having a finite growth is applied to a sweep electrode. A second erasing pulse of negative polarity having a moderate falling of leading edge is applied the held electrode in order to erase its accumulated positive charge after erasing of the partition loads of the selected cell. A luminescence is maintained during one period of hold time on the non-selected parts. An Independent claim is included for: (a) a plasma display
