Abstract
An organic light emitting display including a demultiplexer on each data line that splits and supplies each data signal to a plurality of data lines, thereby decreasing the number of output lines required and reducing production cost. Further, voltages corresponding to the data signals are sequentially charged in data capacitors, while the charged voltages are supplied to the pixels simultaneously allowing the organic light emitting display to display an image with uniform brightness. Scan periods for supplying the scan signals do not overlap with data periods for supplying the data signals thus yielding a stable image. Also, the capacitance of the data capacitor is set to compensate the voltage drop in the first power source line, thereby displaying an image with uniform brightness.
