Abstract:
1. An organic light emitting display, comprising: a first switching element having a control electrode is electrically coupled to a scan line, being electrically coupled between a data line and a first voltage line for transmitting a data signal; a drive transistor having a control electrode is electrically coupled to the first switching element, being electrically coupled between the first voltage line and a second voltage line; an organic light emitting diode electrically coupled to the drive transistor, displaying an image by a current supplied through the drive transistor; a first capacitive element electrically coupled between the control electrode of the drive transistor and the first switching element; a second capacitive element electrically coupled between the first capacitive element and the second voltage line; a second switching element electrically coupled between the first voltage line and the control electrode of the drive transistor; a third switching element electrically coupled between the first switching element and the drive transistor; a fourth switching element electrically coupled between the control electrode of the drive transistor and the second voltage line; a fifth switching element electrically coupled between the drive transistor and the second voltage line; and wherein a first electrode of the first switching element is electrically coupled to the data line, and a second electrode of the first switching element is electrically coupled between a first electrode of the third switching element and a second electrode of the first capacitive element and a first electrode of the second capacitive element.
