Claim Text:
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 display touch crosstalk (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, 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, calculating a DTX compensation value which is a difference between the compensation representative value and the sensing block average value, compensating a user's touch raw data measured in the touch sensing block by adding the DTX compensation value to the user's touch raw data, and sensing the user's touch using the compensated user's touch raw data; wherein the touch sensor includes a compensation block determining part which determines the DTX compensation block so as to make one DTX compensation block include the touch sensing block selected by input of a same multiplexer in accordance with a predetermined order.
