Pixel coupled to three horizontal lines 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 sequentially supplying emission control signals to emission control lines;
• a data driver for supplying data signals to data lines in synchronization with the scan signals;
• and
• pixels located at crossing regions of the data lines, the scan lines, and the emission control lines,
• wherein each of the pixels is located on an i-th horizontal line of a plurality of horizontal lines, where i is a positive integer and each of the horizontal lines includes one of the scan lines and one of the emission control lines, coupled to the one of the scan lines of an (i−1)-th horizontal line of the horizontal lines, the one of the scan lines of the i-th horizontal line, the one of the emission control lines of the i-th horizontal line, and the one of the emission control lines of an (i+1)-th horizontal line of the horizontal lines, and comprises:
• an organic light emitting diode having a cathode electrode coupled to a second power source, an emission of the organic light emitting diode being controlled by one of the emission control signals supplied to the one of the emission control lines of the i-th horizontal line;
• a fourth transistor for controlling an amount of current to the second power source from a first power source via the organic light emitting diode;
• a first capacitor having a first terminal coupled to a gate electrode of the fourth transistor;
• a first transistor coupled between a second terminal of the first capacitor and one of the data lines, and configured to turn on in response to one of the scan signals supplied to the one of the scan lines of the i-th horizontal line;
• a second transistor coupled between the first terminal of the first capacitor and an initial power source, and configured to turn on in response to one of the scan signals supplied to the one of the scan lines of the (i−1)-th horizontal line;
• and
• a third transistor coupled between the second terminal of the first capacitor and a reference power source, and configured to turn off in response to one of the emission control signals supplied to the one of the emission control lines of the (i+1)-th horizontal line.
