Abstract
A structure of a pixel and an organic light emitting display device using the same are provided. The pixel includes an organic light emitting diode; a first transistor controlling the amount of current supplied from a first power source to the organic light emitting diode depending on a voltage applied to a second node; a second transistor coupled between a data line and a first node, and turned on when a scan signal is supplied to a first scan line; a third transistor coupled between the first power source and the first node, and turned on when the scan signal is supplied to a second scan line; a fourth transistor coupled between the first power source and the second node, and turned on when the scan signal is supplied to the second scan line; and a storage capacitor coupled between the first and second nodes.
