Abstract
A driving apparatus for a display panel capable of reducing a circuit scale while suppressing the drop of a contrast includes a scan driver having a first power source for generating a first voltage, generating a scan pulse for bringing the capacitive light emission device to either an ON state or an OFF state based on the first voltage, and applying the scan pulse to the row electrode, a sustain driver having a second power source for generating a second voltage, generating a sustain pulse for allowing the capacitive light emission device set to the ON state to emit light based on the second voltage, and applying the scan pulse to the row electrode, and a reset driver generating a reset pulse for initializing the capacitive light emission device based on the sum of the first voltage and the second voltage, and applying the reset pulse to the row electrode.
