Pixel and organic light emitting display device having the same

An organic light emitting display device comprising:

• a display panel including a plurality of pixels, a plurality of scan lines, a plurality of data lines, a first power voltage providing line, a second power voltage providing line, a plurality of initialization control lines, an emission control lines;
• and
• a panel driver configured to provide a scan signal, a data voltage, a first power voltage, a second power voltage, an initialization control signal, and an emission control signal to drive the pixels,
• wherein each of the pixels includes:
• a first transistor connected between a first node and a second node and having a gate electrode to receive the scan signal;
• a second transistor connected between the second node and a third node in series with the first transistor and having a gate electrode to receive the initialization control signal;
• a driving transistor connected between the first power voltage providing line and the third node and having a gate electrode connected to the first node to control a driving current;
• a third transistor connected between the third node and a fourth node and having a gate electrode to receive the emission control signal;
• an organic light emitting diode, connected between the fourth node and the second power voltage providing line, to emit light based on the driving current;
• a first capacitor connected between the first power voltage providing line and the first node;
• and
• a second capacitor connected between the second node and one of the data lines,
• wherein the display panel is to be driven in a frame which includes:
• a first initialization period to initialize the second node and the fourth node,
• a second initialization period after the first initialization period to initialize a gate voltage of the driving transistor.
