Claim Text:
1. A pixel comprising: an organic light emitting diode; a precharge circuit charging a first voltage corresponding to a data signal supplied through a data line when a scan signal is supplied through a scan line; a pixel circuit charging a second voltage corresponding to the first voltage when a write control signal is supplied through a write control line, and supplying current corresponding to the charged second voltage from a first power source to a second power source via the organic light emitting diode; and a sensing control circuit coupling the data line to an anode electrode of the organic light emitting diode, in response to a sensing control signal supplied through a sensing control line, wherein the sensing control circuit includes: wherein the second capacitor charges a third voltage corresponding to the data signal supplied through the data line, when the second transistor is turned on, in response to a first sensing control signal of the sensing control signal, and wherein the second capacitor discharges the third voltage charged to the data line, when the second transistor is turned on and when the data signal is not supplied to the data line, in response to a second sensing control signal of the sensing control signal.
