ABSTRACT:
An organic light emitting diode display includes a first driving device that includes a first control electrode supplied with a voltage from a first node, and switches a current path between a second node and a third node in accordance with a voltage of the first node; a second driving device that is connected to be symmetrical with the first driving device through the second node and the third node, and includes a second control electrode supplied with a voltage of the first node; a high-level driving voltage source that supplies a high-level driving voltage via the third node; an organic light emitting diode device that is connected between the second node and a ground voltage source; gate and data lines; first to third switch devices; a driving circuit that drives the first to third switch devices; and a storage capacitor connected between the first node and the third node.
