Pixel and organic light emitting display device using the same

An organic light emitting display device comprising:

• a scan driver for sequentially supplying scan signals to scan lines and for sequentially supplying light emission control signals to light emission control lines;
• a control line driver for sequentially supplying control signals to control lines, each of the control signals having a duration longer than that of a corresponding one of the scan signals;
• a data driver for supplying data signals to data lines, the data signals being synchronized with the scan signals;
• and
• pixels at crossing regions of the scan lines and the data lines;
• wherein an ith pixel of the pixels comprises:
• an organic light emitting diode having a cathode electrode coupled to a second power source;
• a second transistor for controlling an amount of current supplied from a first power source to the organic light emitting diode, the first power source being coupled to a first electrode of the second transistor;
• a first capacitor having a first terminal coupled to a gate electrode of the second transistor;
• a first transistor coupled between a second terminal of the first capacitor and a data line of the data lines, the first transistor being configured to turn on when a scan signal of the scan signals is supplied to an ith scan line of the scan lines;
• a third transistor coupled between a gate electrode and a second electrode of the second transistor, the third transistor being configured to turn on when a control signal of the control signals is supplied to an ith control line of the control lines, wherein the control signal supplied to the ith control line is supplied before the scan signal is supplied to the ith scan line such that the control signal supplied to the ith control line is not overlapped with the scan signal supplied to the ith scan line;
• and
• a fifth transistor coupled between the second electrode of the second transistor and the organic light emitting diode, the fifth transistor being configured to turn off when an ith light emission control signal of the light emission control signals is supplied to an ith light emission control line of the light emission control lines,
• wherein an entirety of the control signal supplied to the ith control line is a signal having a reverse polarity of an (i−1)th light emission control signal of the light emission control signals supplied to an (i−1)th light emission control line of the light emission control lines.
