Abstract:
Disclosed is 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 setting a plurality of compensation areas including at least one or more touch sensing blocks, and differentially applying DTX compensation values by compensation area to sense the user's touch in the touch mode. Each of the touch sensing blocks is a sensing unit for a user's touch.
