Abstract
An ac plasma panel is provided with self-shift cpability. Alternate columns of discharge sites, of the panel, referred to as 'display' columns, hold the display information. The latter is shifted to adjacent 'transfer' columns by concurrently applying an excitation pulse to the sites in the display columns and a priming pulse to the sites in the transfer columns. The excitation pulse creates a gas discharge at those display sites which are in the ON state. The excitation and priming pulses, in combination, cause charge from the charge cloud created by each ON-display-site discharge to be transported to the adjacent transfer site. The transported charge represents incipient wall charge for the transfer site and the latter switches to the ON state. An erase pulse is then applied to the display sites. Other pulses are utilized to preclude undesired inter-site interaction.
