Abstract
Disclosed is an organic light emitting display which has a scan driver to supply scan signals to a plurality of scan lines, a data driver to supply data signal to output lines, with a demultiplexer on each output line to supply the data signal to a plurality of data lines is disclosed. The display also has a pixel portion comprising pixels connected to the scan lines, the data lines, and pixel power source lines. There is also a power source line placed between the pixel portion and the data driver to supply first power to the pixel power source lines, and a parasitic capacitor formed on each data line to charge voltage corresponding to the data signal. With this configuration, the number of output lines provided in a data driver is decreased, and an image is displayed with uniform brightness.
