Abstract:
A pixel includes a driving transistor, an organic light emitting diode, a first transistor, and the second transistor. The driving transistor includes a gate electrode coupled to a first node, a first electrode coupled to a second node, and a drain electrode coupled to a third node. The driving transistor controls an amount of drain-source current based on a level of a voltage applied to the first node. The first transistor is coupled between the second node and a data line, and turns on by a scan signal of a scan line. The second transistor is coupled between the first node and an initialization voltage line, and turns on by an initialization signal of an initialization line. The first and second transistors are turned on during a first period.
