ABSTRACT:
A three-electrode surface-discharge alternating-current plasma display panel (AC PDP) has maintenance discharge electrodes that are in parallel with one another and addressing electrodes that are orthogonal to the maintenance discharge electrodes. The maintenance discharge electrodes are connected to one another, and the maintenance discharge electrodes are independent of one another and correspond to display lines that form a screen of the PDP. Wall charges are accumulated to serve as memory media. Display data are written to the screen in separate two periods, i.e., an addressing period in which wall charges are accumulated according to the display data, to prepare for maintenance discharge (sustain discharge) and a maintenance discharge period in which the maintenance discharge is repeated to emit light. The maintenance discharge in the maintenance discharge period is carried out on every other display line and the accumulation of wall charges in the addressing period is carried out on every display line. This arrangement scans every other display line on the screen according to interlaced display signals (video signals) without producing new display data by line interpolation, thereby shortening an addressing time.
