Patent ID: 6982688

Claim:
A driving apparatus for a display panel including a plurality of drive lines and a plurality of scanning lines intersecting with said plurality of drive lines, a plurality of capacitive light emitting elements connected between said scanning lines and said drive lines at each of a plurality of intersecting positions by said drive lines and said scanning lines and having polarities, said driving apparatus comprising: a controller for selecting one scanning line of said plurality of scanning lines in order at a predetermined timing to specify as a light emission drive line a drive line corresponding to a capacitive light emitting element driven to emit light on said one scanning line, of said plurality of drive lines; a scanning device for supplying said one scanning line with a first predetermined potential, and supplying scanning lines other than said one scanning lines of said plurality of scanning lines with a second predetermined potential higher than said first predetermined potential; and a driver for supplying said light emission drive line with a driving current to apply said capacitive light emitting element driven to emit light with a positive voltage equal to or higher than a light emission threshold voltage in a forward direction and supplying drive lines other than said light emission drive lines of said plurality of drive lines with a third predetermined potential higher than said first predetermined potential and lower than said light emission threshold voltage, wherein said third predetermined potential is generated from a current discharge terminal of a voltage source connected to a predetermined load circuit for supplying a power supply voltage to said predetermined load circuit.
