Summary:In one aspect, there is an organic light emitting display comprising: a display panel including subpixels; a data driver that supplies a data signal to the display panel; a scan driver that supplies a scan signal to the display panel; and a sensing circuit unit that measures the threshold voltages of driving transistors through sensor transistors of the display panel and prepares compensation data, wherein the scan driver turns on the sensor transistor of a selected subpixel to measure the threshold voltage of the driving transistor of the selected subpixel during a vertical blank interval of the display panel, and turns on the sensor transistors of non-selected subpixels to supply voltages below the threshold voltage of organic light emitting diodes to the non-selected subpixels during an image display interval of the display panel.
