Abstract:
1. An organic light emitting display, comprising: a driving transistor electrically coupled to a first power line; a first switch electrically coupled to the driving transistor and an emission line; a second switch electrically coupled to the driving transistor and a previous scan line; a third switch electrically coupled to the first switch and a data line; a fourth switch electrically coupled to the data line and the third switch; a fifth switch electrically coupled to the driving transistor and a scan line; a sixth switch electrically coupled to the fifth switch; a first capacitor electrically coupled to the second switch and the third switch; a second capacitor electrically coupled to the third switch and the fifth switch; and an organic light emitting diode electrically coupled to the driving transistor and a second power line, the organic light emitting diode being directly coupled to the driving transistor, wherein the first switch, the second switch, the third switch, the fourth switch, and the fifth switch are P-channel field effect thin-film transistors, and the sixth switch is a N-channel field effect thin-film transistor, wherein: the second switch and the sixth switch are electrically coupled to the third power line, and when the previous scan line has a low level, the scan line has a high level, the emission line has a low level, a first electrode of the first capacitor, a first electrode of the second capacitor and a control electrode of the driving transistor are electrically coupled to a third power line, such that the first electrode of the first capacitor, the first electrode of the second capacitor and the control electrode of the driving transistor are initialized to a voltage level of the third power line.
