Voltage generator and display device having the same

摘要

A display device including a voltage generator is disclosed. The voltage generator includes an analog driving voltage generator to convert a source voltage from an external source to an analog driving voltage and to output the analog driving voltage through an output terminal, a capacitor connected between the output terminal and a ground voltage node, and a discharge circuit connected between the output terminal and the ground voltage node to discharge a current at the output terminal in response to a blank synchronization signal.
