Abstract
A display that has rush current reduction during power-on is provided. A display panel that displays an image includes a gate line and a data line. A voltage generator receives a supply voltage and outputs a gate-on voltage and a gate-off voltage to first and second output nodes, respectively. The voltage generator includes a pull-up capacitor that is charged for a first time period of a power-off period and is discharged for a second time period of the power-off period to increase a voltage level of the second output node, the first and second time periods being consecutive periods of the power-off period. A gate driver selectively applies a gate-on voltage or a gate-off voltage to the gate lines, and a data driver applies a data voltage to the data line.
