Arrangement utilizing the mechanism of charge spreading to provide an ac plasma panel with shifting capability

摘要

Erase and "shifting write" pulses are applied across pairs of adjacent sites in each row of an ac plasma panel in a predetermined sequence. The shifting write pulse occurs during the conventional erase time period and its magnitude and duration are such that it will switch an OFF site on the ON state only if that site has received spread wall charge from an adjacent ON site. In addition, a scan erase pulse is used to temporarily lower the wall charge of certain ON sites when shifting is to be initiated, thereby preventing possible backshifting.
