Abstract
The invention pertains to an alternating type of plasma panel. Each pixel is defined by three parallel and coplanar electrodes and by an electrode which is perpendicular to the other three electrodes and is separated from the other three electrodes by at least one dielectric layer. Two of the three parallel electrodes are connected to circuits giving the refresh signals to each pixel during operation. The electrode perpendicular to the other three and that electrode, of the other three parallel electrodes, which is not connected to a refresh circuit, are connected to circuits that give addressing signals to each pixel during operation. The electrodes that are connected to the refresh circuits constitute two arrays of electrodes connected to two refresh circuits.
