Abstract
A touch display device includes a color filter substrate, and a thin film transistor substrate facing the color filter substrate. The thin film transistor substrate includes a common electrode layer. A force sensing electrode layer is formed on the color filter substrate. The common electrode layer includes a plurality of common electrodes. The common electrodes function as electrodes of the touch display device for sensing a touch position. The common electrodes and the force sensing electrode layer cooperatively form capacitors for sensing a touch force, their capacitance varying as a result of the distance between them being reduced.
