ABSTRACT:
An apparatus for driving a light emitting panel which selects one scanning line from a plurality of scanning lines, designates at least one drive line of a plurality of drive lines corresponding to at least one capacitive light emitting element driven to emit light on the one scanning line, applies the one scanning line with a first predetermined potential, applies scanning lines other than the one scanning line with a second predetermined potential higher than the first predetermined potential, supplies a driving current to the at least one line so as to apply the at least one capacitive light emitting element with a positive voltage equal to or higher than a light emission threshold voltage in the forward direction, and applies drive lines other than the at least one drive line with a third predetermined voltage lower than the light emission threshold voltage and higher than the first predetermined potential.
