Abstract

Discussed are a current sensing circuit capable of compensating for degradation of an organic light emitting diode by sensing a current of the organic light emitting diode, and an organic light emitting diode display having the same. The current sensing circuit according to an embodiment includes a plurality of sensing modules configured to sense a pixel current from a display panel having an organic light emitting diode on each of a plurality of pixels, and to output a sensing voltage according to a sensing result; and an analog-to-digital converter configured to convert the sensing voltage into an analog-to-digital voltage, and to output sensing data.
