Abstract
An organic light emitting diode (OLED) display device and a method of driving the same are discussed. The method includes sensing a threshold voltage and mobility of a driving thin film transistor (TFT) included in each pixel using a sensing line connected per pixel and supplying the threshold voltage and the mobility to a timing controller in a measurement mode, by a data driver, and supplying image data input from an external source to the data driver by a timing controller, the timing controller adding and multiplying an offset value and gain value corresponding to the threshold voltage and mobility of the driving TFT, sensed by the data driver in the measurement mode, with the image data to compensate the image data, wherein the compensation of the image data includes varying a weight of the gain value according to luminance of the image data.
