Abstract

The present disclosure provides a light-emitting display including a display panel, a first circuit, a second circuit, and a compensation circuit. The display panel includes a pixel having an organic light-emitting diode. The first circuit supplies a data voltage to the pixel. The second circuit performs a first sensing operation for sensing a voltage stored at an anode of the organic light-emitting diode and a second sensing operation for sensing a parasitic capacitance of the organic light-emitting diode. The compensation circuit compensates for degradation of the organic light-emitting diode based on a sensed value outputted from the second circuit.
