Abstract: A pixel capable of displaying images with substantially uniform luminance and an organic light emitting display device using the same are provided. An organic light emitting display device is driven in a frame divided into a reset period, a compensation period and an emission period. The organic light emitting display device includes pixels coupled to scan lines and data lines. First and second control lines are commonly coupled to the pixels. A control line driver supplies first and second control signals to the respective first and second control lines. A scan driver concurrently supplies a scan signal to the scan lines during a time in the reset and compensation periods. A data driver supplies a reset voltage to the data lines during the time in the reset and compensation periods.
