Abstract
A display device includes a display panel which is driven in a mode selected from among a plurality of modes including different luminance values, a voltage generator which generates a driving voltage, a resistor connected to an output terminal, from which the driving voltage is output, a current sensing unit connected in parallel to the resistor, where the current sensing unit measures a voltage value across both ends of the resistor and calculates a driving current value using a resistance value of the resistor and a measured voltage value, and a maximum current calculating unit which calculates a maximum measured current value corresponding a the luminance value of a selected mode and outputs a selection signal corresponding to the maximum measured current value, and the current sensing unit sets a maximum measured voltage value corresponding to the maximum measured current value in response to the selection signal.
