Abstract
A display device includes a display panel including a pixel which receives a driving voltage through a first voltage line, a voltage generator which provides the driving voltage which has a first voltage level to the first voltage line and determines a voltage level of the driving voltage based on a voltage control signal, a current sensor which senses a current level of the first voltage line and outputs a current signal corresponding to the sensed current level, and an overcurrent controller which outputs the voltage control signal which changes the voltage level of the driving voltage when a difference value between present and previous current levels of the current signal is a reference value or greater. The voltage level of the driving voltage changes to a second voltage level lower than the first voltage level when the difference value is the reference value or greater.
