Patent ID: 7903060

Claim:
An organic light emitting diode display, comprising: a first driving device that includes a first control electrode supplied with a voltage from a first node, and is connected between a second node and a third 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; a gate line and a data line which are crossed each other; a first switch device that selectively connects the data line with the first node; a second switch device that selectively connects the second node with the data line; a third switch device that selectively connects the first control electrode with the second control electrode; a driving circuit that drives the first to third switch devices to turn-on the first to third switch devices, thereby forming a parallel current path between the second node and the third node via the first and second driving devices for a first period, and then to turn-off the first to third switch devices, thereby forming a series current path between the second node and the third node via the first driving device for a second period; and a storage capacitor that is connected between the first node and the third node.
