Patent ID: 7605781

Claim:
A display panel driving method for driving a display panel, the display panel including a plurality of row electrode pairs, a plurality of column electrodes arranged intersecting the plurality of row electrode pairs, and capacitive light-emitting elements arranged at intersecting points of the row electrode pairs and the column electrodes, and in which driving is performed by repeating a driving step that comprises a reset step, an addressing step, and a sustain step, wherein: an output terminal of a column electrode drive circuit connected to the column electrodes is connected to a switch having a parasitic diode, and during the period of the sustain step, said output terminal of said column electrode drive circuit is maintained in a high impedance state, and bipolar pulse signals which are a half cycle out of phase with each other are supplied to each of a first row electrode and a second row electrode that constitute each of the row electrode pairs, wherein a period exists wherein a negative polarity pulse and a positive polarity pulse respectively of said bipolar pulse signals are simultaneously applied to one electrode and the other electrode of each of said row electrode pairs respectively, and wherein a leading edge of said negative polarity pulse applied to said one electrode and a leading edge of said positive polarity pulse applied to said other electrode exist at different timings, and a trailing edge of said negative polarity pulse applied to said one electrode and a trailing edge of said positive polarity pulse applied to said other electrode exist at different timings.
