Abstract

A display device includes a display panel including a plurality of pixels, a power management circuit which supplies a power supply voltage to the plurality of pixels through a power supply line, a current sensing circuit which generates a digital current code by sensing a panel current flowing through the power supply line, and a controller which determines a peak gray level and a panel load by analyzing input image data, determines a voltage level of the power supply voltage based on the peak gray level and the panel load, and sets a conversion time, during which the panel current is converted into a digital current code, based on the voltage level of the power supply voltage.
