Claim:
An organic light emitting display comprising: a scan driver for supplying scan signals to a plurality of scan lines; a data driver for supplying data signals to a plurality of output lines; a plurality of demultiplexers coupled to the plurality of output lines for supplying corresponding ones of the data signals from each one of the output lines to a plurality of data lines, the plurality of data lines including a first group, a second group, and a third group; a display portion coupled with the plurality of scan lines, the plurality of data lines, and a pixel power line, and including red pixels each having a red organic light emitting diode, green pixels each having a green organic light emitting diode, and blue pixels each having a blue organic light emitting diode; wherein a plurality of first parasitic capacitances are formed at the first group of the plurality of data lines, the first parasitic capacitances associated with the red pixels, for storing first voltages corresponding to the data signals for the red pixels during a data period, and for applying the stored first voltages to the red pixels in accordance with the scan signals during a scan period different from the data period; wherein a plurality of second parasitic capacitances are formed at the second group of the plurality of data lines, the second parasitic capacitances associated with the green pixels, for storing second voltages corresponding to the data signals for the green pixels during the data period, and for applying the stored second voltages to the green pixels in accordance with the scan signals during the scan period; wherein a plurality of third parasitic capacitances are formed at the third group of the plurality of data lines, the third parasitic capacitances associated with the blue pixels, for storing third voltages corresponding to the data signals for the blue pixels during the data period, and for applying the stored third voltages to the blue pixels in accordance with the scan signals during the scan period, wherein the first parasitic-capacitances, the second parasitic capacitances, and the third parasitic capacitances have different capacitance values, and wherein the capacitance value of the second parasitic capacitances is greater than the capacitance value of the first parasitic capacitances and the capacitance value of the third parasitic capacitances is smaller than the capacitance value of the first parasitic capacitances.
