Abstract: The present disclosure relates to a display device and a compensation method and more particularly to a method for sensing mobility of a driving TFT of subpixels while an image is being driven by a display device, and a display device performing the method. A sensing method for compensation, which is performed while a display device is being driven, includes charging, in an Nth frame period, a node M of a shift register A connected to a jth gate line of a display panel. The method also includes charging, in the Nth frame period, a node M of a shift register B connected to a Kth gate line of the display panel. The method further includes sensing, in a next blank period to the Nth frame period, subpixels connected to the jth gate line and sensing subpixels connected to the Kth gate line in the blank period.
