Abstract
An electronic device includes a display device including a display panel, a touch panel, and a touch sensing circuit configured to sense a touch input. The electronic device also includes an input pen configured to provide, to the touch sensing circuit, information on intensity of pressure applied to the display device. The touch panel includes touch pressure sensors and signal lines connected to the touch pressure sensors. Each touch pressure sensor has an area per unit length that increases along an extended direction of each touch pressure sensor. Each touch pressure sensor has a resistance that varies with an intensity of pressure and an area of pressure applied to the touch pressure sensors.
