Abstract
An organic light emitting display includes: pixels respectively positioned in areas defined by scan lines and data lines; and a data driver configured to supply a data signal to the data lines, the data signal includes a first data signal corresponding to an emission of the pixels and a second data signal corresponding to a non-emission of the pixels, wherein each pixel includes: an organic light emitting diode; a first transistor coupled to the organic light emitting diode, the first transistor configured to be a current source driven in a saturation region; a second transistor coupled as a current mirror to the first transistor, the second transistor configured to control an amount of a current flowing in the first transistor; and a third transistor coupled to the second transistor, the third transistor configured to be a switch driven in a linear region, according to the data signal.
