Abstract
A driving method enables an improvement in emission efficiency and achievement of a higher degree of brightness when employing the address while display driving (AWD) scheme. Taking a 3-bit 8-gradation display as an example, a first H period (one horizontal scan period) of each subfield is divided into 3 regions (first region, second region, and third region in the order of time), and, in each of the lines, an address period (address pulse Pand scan pulse P) of the subfield SFis set in the first region, an address period of subfield SFis set in the second region, and an address period of the subfield SFis set in the third region. The regions other than those in which the address period is set are used as the sustain period, and a time length of each sustain pulse Pis set to ⅓ of the length of the H period. A reset period achieved by a reset pulse Pand a priming period achieved by a priming pulse Pare set in the region where the address period is set.
