Abstract

Disclosed is a display device which includes a display panel including a plurality of pixels, a voltage generator providing a driving voltage to the plurality of pixels, and a driving controller. The driving controller includes an overcurrent protecting circuit. The overcurrent protecting circuit includes a first logic circuit comparing a limit current with a sensing current to generate a first comparison result, a second logic circuit comparing a load with a limit load to generate a second comparison result and comparing the driving voltage with a limit voltage to generate a third comparison result. When the first comparison result indicates the sensing current is greater than or equal to the limit current, the second comparison result indicates the load is greater than the limit load and the third comparison result indicates the driving voltage is greater than the limit voltage, a driving voltage controller maintains the driving voltage.
