Patent ID: 8269693

Claim:
A method comprising: driving a plasma display panel to perform display on a screen area of the plasma display panel, the panel including sustain electrodes and scan electrodes in a first direction and including address electrodes in a second direction, the method using a subfield method, where one field time period is divided into a plurality of subfields, and an address-, display-period separation method, wherein: the screen area of the panel, a group of display lines of the panel, and a group of display columns of the panel are respectively divided into a plurality of first regions (H) in the first direction and divided into a plurality of second regions (V) in the second direction, a plurality of address energy recovery circuit blocks are provided corresponding to the first regions (H), as an address energy recovery circuit that is connected to a group of the address electrodes of the panel and recovers energy, and for each of the subfields and for each of the first regions (H) of which the address energy recovery circuit blocks are respectively in charge, an operation of the address energy recovery circuit block corresponding to each first region (H) is turned ON or OFF for each of the second regions (V) according to a switching load of an address pulse applied to a group of address electrodes in each second region (V).
