Abstract: An organic light emitting display can improve display quality by securing a charging time of a data signal. An organic light emitting display includes pixels, a data driver, a plurality of data drivers, and a control signal generator. The pixels are respectively positioned at areas defined by scan lines and data lines. The data driver sequentially supplies i (i is a natural number greater than or equal to 2) data signals to each of output lines during one horizontal period. The plurality of data dividers are respectively coupled to the output lines, and supply the i data signals to i data lines. The control signal generator sequentially supplies i control signals to the data dividers, corresponding to the i data signals. In the organic light emitting display, the data dividers supply a corresponding data signal to each data line during the one horizontal period.

Abstract: A pixel includes a driving circuit, a first organic light emitting diode, a second organic light emitting diode, and a self-repair circuit. The driving circuit supplies current based on a data signal supplied through a data line. The first organic light emitting diode is coupled to the driving circuit through a first current path. The second OLED is coupled to the driving circuit through a second current path. The self-repair circuit interrupts the first current path and supplies the current to the second current path when the first organic light emitting diode has a defect.
