The present disclosure relates to a display device and a timing controller. The display device includes a panel on which a number of subpixels are disposed and a characteristic sensing circuit sensing characteristic values of the number of subpixels. When a difference between the characteristic value of a specific subpixel among the number of subpixels and a reference value exceeds a predetermined range, the characteristic sensing circuit generates coordinate data of the specific subpixel. The display device includes a host controller recognizing a user manipulation based on the coordinate data.
