Abstract:
1. An organic light emitting display, comprising: a first switching element including a control electrode directly coupled to a scan line and being electrically coupled between a data line and a first voltage line; a driving transistor electrically coupled between the first voltage line and a second voltage line, wherein the driving transistor is electrically coupled to a fourth switching element adapted to initialize a voltage stored in a first storage capacitor and a second storage capacitor, the second storage capacitor being different from the first storage capacitor, by applying an initialization voltage to a control electrode of the driving transistor; a second switching element including a control electrode electrically coupled to a light emission control line and being electrically coupled between the first voltage line and the driving transistor; a third switching element including a control electrode directly coupled to the scan line and being electrically coupled between the second switching element and the driving transistor; the first storage capacitor being directly electrically coupled between the first voltage line and the control electrode of the driving transistor; the second storage capacitor being electrically coupled between the first storage capacitor and the second switching element, the first storage capacitor including a first electrode directly electrically coupled to the first voltage line and a second electrode directly electrically coupled between a control electrode of the driving transistor and a first electrode of the second storage capacitor; and an organic light emitting diode electrically coupled between the driving transistor and the second voltage line.
