An apparatus for driving capacitive light emitting diodes which can be
reduced in size. For supplying a capacitive light emitting diode with a
driving pulse which varies the voltage with a predetermined amplitude
through a driving line, the driving apparatus comprises a resonance
current path including a capacitor, a first switching element for
supplying the driving line with a current in accordance with charges
accumulated on the capacitor when it is on, and a second switching
element for grounding one electrode of the capacitor when it is on,
thereby supplying the other electrode of the capacitor with a current in
accordance with charges accumulated in the capacitive light emitting
element through the driving line.
