A pixel, an organic light emitting display including the same, and a driving method thereof, in which a gradation is represented using the frequency characteristic of an organic light emitting diode. The organic light emitting display includes a plurality of pixels which are connected by a plurality of scan lines for supplying scan signals, a plurality of data lines for supplying data signals, and a plurality of power source lines, each pixel having: a frequency supplying line through which a frequency signal corresponding to a sub-frame is supplied; a pixel circuit outputting a current corresponding to an output obtained by applying a logical operation to a corresponding one of the data signals and the frequency signal; and an organic light emitting diode for emitting light based on the current outputted from the pixel circuit. With this configuration, a desired gradation can be represented using the frequency characteristic of the organic light emitting diode on the basis of the sum of various brightness depending on a digital data signal and frequency signals that are different per sub-frame.
