Abstract
A PDP apparatus in which a large-sized plasma display panel, whose electrodes have large drive requirements, is driven by using already existing driver ICs, and a PDP apparatus in which the operating conditions when a plasma display panel is driven by using a plurality of driver ICs have been improved, are disclosed. According to a first aspect, one electrode of the plasma display panel is driven by combining a plurality of drive signals output from the driver IC and, according to a second aspect, in a configuration in which a plurality of electrodes are driven by a plurality of identical driver ICs, when some of a plurality of outputs of the driver ICs are not connected to the electrodes and not used, the unused outputs are distributed in each driver IC as evenly as possible.
