Abstract:
A pixel according to the present invention includes: an organic light emitting diode having a cathode electrode connected to a second power; a first transistor controlling an amount of current supplied from a first power line connected through a third node to the organic light emitting diode connected through a second node in correspondence to the voltage applied to a first node; a storage capacitor connected between the first node and the second power; a second transistor connected between the first node and the third node and being turned on when a scan signal is supplied to a scan line; and a third transistor connected between the second node and the data line, and being turned on when the scan signal is supplied.
