Abstract
An organic light emitting display capable of improving data charging time, includes pixels at crossing regions between scan and data lines and configured to control an amount of current supplied from a first to a second power source, a charge unit adjacent to an adjacent pixel of the pixels and coupled to the same data line as the adjacent pixel, a scan driver for supplying scan signals to the scan lines, a data driver for supplying data signals to the data lines in synchronization with the scan signals, and a comparison unit in a channel of the data driver to compare a data signal supplied to a current line with a data signal supplied to a previous line and to control coupling between the charge unit and the data line according to a comparison result in a partial period of a period in which the scan signals are supplied.
