1. A display device comprising:

  • a timing controller for driving one frame by a time division method so as to alternately perform a displaying driving mode for displaying an image on a display panel and a touch sensing mode for sensing a user'"'"'s touch; and

    a touch sensor for determining a DTX compensation block including at least one touch sensing block corresponding to a unit for sensing the user'"'"'s touch;

    calculating a compensation representative value which is a DTX value corresponding to a first average of grayscale values applied to a plurality of pixels overlapped with the DTX compensation block, and calculating a sensing block average value which is the DTX value corresponding to a second average of grayscale values applied to a plurality of pixels overlapped with the touch sensing block; and

    sensing the user'"'"'s touch by compensating for touch data in accordance with a difference between the compensation representative value and the sensing block average value.
