    Abstract: A display device includes a display panel, a touch sensor, and a conductive layer. The touch sensor is disposed on the display panel, and is configured to detect a pressure of a touch and calculate a position and an intensity of the touch. The conductive layer is disposed on the touch sensor. The touch sensor includes a plurality of first electrodes, a plurality of second electrodes spaced apart from the plurality of first electrodes, and a plurality of elastic members disposed between the plurality of first electrodes and the plurality of second electrodes. The display device is configured to calculate a variation a of capacitance between the plurality of first electrodes and the plurality of second electrodes that is caused by a transformation of the elastic member in response to the pressure of the touch.
