    Abstract: A display device of the disclosure includes a display panel including pixels, a first sensor configured to sense mobility of the pixels, and a second sensor. The first sensor generates an initial sensing value using a first process to sense the mobility during a first time period from a power-on time point of the display device to a display start time point, and generates a first sensing value using a second process to sense the mobility after the display start time point. The second sensor senses whether the display panel is an abnormal state based on the initial sensing value and the first sensing value.
