Abstract: An organic light emitting diode (OLED) display is discussed. The OLED display is capable of duty driving for controlling an emission duty of an OLED in one frame. One frame for the duty driving includes a programming period, an emission period, and a non-emission period. In the programming period, a first data voltage is applied to a gate node in response to a scan signal and a reference voltage is applied to a source node in response to a sensing signal. In the non-emission period, a second data voltage is applied to the gate node in response to the scan signal. The first data voltage corresponds to input video data to be applied to a first pixel. The second data voltage corresponds to input video data to be applied to a second pixel different from the first pixel.

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.
