    Abstract: An organic light emitting display includes a display panel including display lines, on which a plurality of pixels each including an organic light emitting diode and a driving thin film transistor (TFT) are formed. The display lines are sequentially charged to an image display data voltage in response to an image display gate pulse in an image display period of one frame. A sensing target display line among the display lines outputs a sensing voltage corresponding to changes in electrical characteristic of the driving TFT included in each pixel in response to a sensing gate pulse during a vertical blank period excluding the image display period from the one frame and then is charged to a luminance recovery data voltage. The sensing gate pulse is supplied in the same pulse shape as the image display gate pulse in a predetermined period for charging the luminance recovery data voltage.
