Patent number: 8203507Abstract: A drive method of a plasma display panel that can increase the dark contrast, without causing a discharge failure. When a discharge cell that assumes a black display state in a first field from among first and a second fields that are adjacent in time and switches to a display state representing a brightness other than black in the second field is detected as a lighting transition cell, at least one drive of the below-described first and second forced lighting drives is executed. In the first forced lighting drive, the lighting transition cell is forcibly set into the lighting mode only in the address process of a predetermined subfield within the field in the first field. In the second forced lighting drive, an adjacent discharge cell that is adjacent to the lighting transition cell is forcibly set into the lighting mode only in the address process of the predetermined subfield in the second field.Type: GrantFiled: February 29, 2008Date of Patent: June 19, 2012Assignee: Panasonic CorporationInventors: Shunsuke Itakura, Mitsuhiro Ishizuka, Kazuo Yahagi, Tetsuya Shigeta, Hirofumi Honda
