    Abstract: Provided are a display device and a touch sensing method of a display device. The display device includes a timing controller temporally dividing one frame period and driving a display panel such that a display mode for displaying an image in the display panel and a touch mode for sensing a user's touch are alternately driven, and a touch sensing unit detecting the user's touch with a touch raw data difference between adjacent touch sensing blocks in the touch mode. In the display mode, the touch sensing unit generates a display compensation value for compensating for an error of the touch raw data due to a differential of display data applied to the adjacent touch sensing blocks to detect the user's touch.
