Abstract:
1. A display device, comprising: 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 setting a plurality of compensation areas comprising at least one or more touch sensing blocks, and differentially applying DTX (display touch crosstalk) compensation values by compensation area to sense the user's touch in the touch mode, each of the touch sensing blocks being a sensing unit for a user's touch, wherein, each of the compensation areas is set to a predetermined width based on a distance between a data driver and the compensation area, each of the DTX compensation values is a value for compensating for an error of touch data caused by changes in respective grayscale values applied to pixels corresponding to a specific touch sensing block, and a total number of compensation areas is determined by comparing the DTX compensation values and a touch threshold value.
