Abstract: A touch display device includes a touch sensor, a visual accelerator, and a display. The touch sensor senses a touch. The visual accelerator visualizes the touch. The display displays information corresponding to the visualized touch. When the touch is outside a visual acceleration area, the visual accelerator does not process the touch. When the touch is in the visual acceleration area, the visual accelerator visualizes the touch on the display.

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.
