Abstract:
1. An organic light emitting display comprising: a display panel comprising sub pixels disposed at intersections of data lines and first and second scan lines; a data driver alternately outputting a positive data signal and a negative data signal to the data lines; and a scan driver respectively outputting a first scan signal and a second scan signal to the first scan lines and the second scan lines, wherein each of the sub pixels comprises a first driving circuit and a second driving circuit which individually drive at least two organic light emitting diodes, and the first driving circuit and the second driving circuit respectively comprise at least one switching transistor, at least one driving transistor, and at least one capacitor, wherein one of the first driving circuit and the second driving circuit performs a light-emitting operation such that the organic light emitting diode corresponding to the one of the first and second driving circuits emits light and the other one compensates for the threshold voltage of the driving transistor.
