Abstract:
1. A driving apparatus driving a display panel that displays an image in response to a driving signal, the driving apparatus comprising: a voltage generator receiving an external supply voltage and producing therefrom an internal supply voltage by boosting the external supply voltage; a driving unit outputting the driving signal based on the internal supply voltage; and a reset signal generator receiving the external supply voltage and the internal supply voltage and producing a reset signal that resets the driving unit, wherein the reset signal generator includes: a fourth transistor having a gate connected with the drain of the first transistor, a drain gate connected with the drain of the second transistor, and a source connected with the ground supply voltage; and a reset controller generating the reset signal in response to a first logic signal; wherein when the internal supply voltage exceeds the external supply voltage in a rising period of the internal supply voltage, the first node outputs the internal supply voltage as the first logic signal.
