An apparatus for driving a display panel having drive lines and capacitive
light emitting elements. The apparatus sequentially selects one scanning
line from the scanning lines every scanning period of input video data
including a gradation level to specify a drive line corresponding to at
least one capacitive light emitting element driven to emit light on the
one scanning line in accordance with the input video data, generates a
driving signal having a pulse width in accordance with the gradation
level every scanning period, and applies the one capacitive light
emitting element with a voltage equal to or higher than a light emission
threshold voltage in a forward direction for a duration in which the
driving signal is generated, through the one scanning line and the
specified drive line, and applies the specified drive line with a
predetermined potential in response to elimination of the driving signal
to decrease the voltage applied to the one capacitive light emitting
element in the forward direction to a voltage lower than the light
emission threshold voltage.
