Abstract
A driving voltage sensing circuit and a display device including the same. Deterioration of an organic light-emitting diode (OLED) disposed in each of subpixels is effectively compensated for by accurately sensing a change of charged capacitance depending on a current flowing through the organic light-emitting diode in a deterioration sensing period of the organic light-emitting diode. A driving voltage-for-sensing deterioration, applied to the display panel in the deterioration sensing period of the organic light-emitting diode, is maintained within a reference range. The deterioration of the organic light-emitting diode is accurately sensed by maintaining the driving voltage-for-sensing deterioration, applied in the deterioration sensing period, within the reference range.
