ABSTRACT:
An organic light emitting display device and a driving method for the same is provided. The device includes a data driver that can cause a display of an image having a uniform luminance. The data driver includes a ramp pulse generating part for generating a ramp pulse. The data driver also includes a current digital-to-analog converting part for generating a data current using data provided to the data driver. The data driver also includes a current control part for providing the ramp pulse to data lines coupled to a pixel and comparing a pixel current from the pixel with the data current to control providing of the ramp pulse to the data lines. The pixel current corresponds to the ramp pulse.
