Display device and method of driving the same

Display apparatus supplies a driving power to the display panel, the pixels through the power line having a plurality of pixels, and black from the power supply portion, a frame non-emission period of the interval on the basis of the crack signal stopping the supply of the driving power cracking signal by displaying an image and measuring the sensed current passing through the panel-drive section, and a power supply line for supplying a driving signal to the pixels for displaying a valid image from the light-emitting period, and monitoring the sensed current during the successive M-frame interval crack detection of generating comprises parts.
