Abstract:
Disclosed is a touch sensing display device capable of sensing both touch position and touch force, shortening a driving time for the touch sensing, and improving touch sensing efficiency, and an apparatus for driving thereof. The display device can include a color filter, a plurality of first touch electrodes for touch force sensing, and a plurality of second touch electrodes for touch position sensing and separated from the first touch electrodes by the color filter. The display can also include a force sensing touch driver for the first touch electrodes and a touch position touch driver for the second touch electrodes.
