摘要：
A driving method for a display apparatus produces light emission by applying a sustain discharge pulse repeatedly. A pulse width of the sustain discharge pulse is varied within one subfield and is controlled in accordance with the amount of voltage drop of a sustain discharge voltage. A display apparatus has a display panel section, a data converter, a power supply section, and a sustain discharge pulse control circuit. The data converter receives an image signal and supplies image data suitable for the display apparatus to the display panel section, and the power supply section supplies power to the display panel section. Further, the sustain discharge pulse control circuit varies a pulse width of sustain discharge pulse within one subfield and controls the pulse width of the sustain discharge pulse in accordance with the amount of voltage drop of a sustain discharge voltage.
