    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 scan driver includes scan signal outputting circuits, at least one of the scan signal outputting circuits includes a driving circuit and a buffer circuit. The driving circuit includes driving transistors. The driving circuit provides first and second driving signals to first and second driving nodes, respectively by turning on or off the driving transistors in response to clock signals and a scan input signal. The buffer circuit includes buffer transistors. The buffer circuit outputs a scan signal at an output node by turning on or off the buffer transistors in response to the first and second driving signals. The at least one of the scan signal outputting circuits performs a back-biasing voltage applying operation on at least one of the driving transistors and the buffer transistors when the driving transistors and the buffer transistors are turned on or off.
