Abstract:
1. An organic light emitting display comprising: a scan driver configured to supply scan signals to a plurality of scan lines; a data driver configured to supply data signals to a plurality of output lines; a plurality of demultiplexers, each configured to selectively supply the data signals from a single output line to a plurality of data lines; a pixel portion comprising a plurality of pixels, the pixel portion being connected to the scan lines, the data lines, and a plurality of pixel power source lines; a first power source line connected to the pixel power source lines at a first end of each of the pixel power source lines; and a plurality of capacitors, wherein each of the capacitors is configured to store a charge corresponding to the data signal on a corresponding data line, wherein an auxiliary power source line is placed between the pixel portion and the data driver and is connected to the pixel power source lines at a second end of each of the pixel power source lines, wherein a first of the capacitors has a first width and a first capacitance, and the first capacitor is formed by a first data line having the first width and the auxiliary power source line, and a second of the capacitors has a second width and a second capacitance, and the second capacitor is formed by a second data line having the second width and the auxiliary power source line, and wherein the first and second widths are different and the first and second capacitances are substantially equal, and wherein the scan driver supplies the scan signals during a first period defined in one horizontal period, and the data driver supplies the data signals to the plurality of output lines during a second period defined in the one horizontal period, wherein the first and second periods do not overlap.
