Abstract
Provided is a pixel including an organic light emitting diode, a driving circuit, and a light receiving circuit. The driving circuit is configured to supply a driving current corresponding to a data signal supplied through a data line during a scan period to the organic light emitting diode during an emission period, and to supply a first sensing current corresponding to threshold voltage/mobility information of a driving transistor or degradation information of the organic light emitting diode to a feedback line during a current sensing period. The light receiving circuit is configured to supply a second sensing current corresponding to luminance of the organic light emitting diode to the feedback line during the emission period.
