Summary:touch sensing unit includes a touch sensor, a sensor line, a piezoelectric area, and a touch sensor controller. The touch sensor is arranged in an island shape. The sensor line is connected to the touch sensor. The piezoelectric area overlaps the touch sensor and is arranged in an island shape. The touch sensor controller receives a voltage from the piezoelectric area when the piezoelectric area receives pressure and determines a magnitude of the pressure based on the voltage.
