Abstract

An organic light emitting display device includes: a scan driver for supplying scan signals to scan lines and an emission control signal to an emission control line during a scan period; a data driver for supplying data signals to data lines; a second power supply supplying a second power at a high voltage level during the scan period and at a low voltage level during an emission period; and a plurality of pixels located at crossing regions of the scan lines and the data lines, the pixels controlling the amount of current supplied through organic light emitting diodes (OLEDs), each of the pixels located in an i-th horizontal line including: a second transistor having a second electrode coupled with an OLED; and a first transistor coupled between the second transistor and a data line and turned on when a scan signal is supplied to the i-th scan line.
