    Abstract: A power supply and a method of driving the same. A converter receives an input voltage from a battery and outputs a first voltage through an output terminal, such that a ground voltage of the output terminal changes. A pulse width modulation (PWM) controller controls the converter to adjust the voltage level of the first voltage. The ground voltage is applied to the converter as a direct current (DC) voltage during a first time and as a pulse wave having a predetermined amplitude during a second time. The PWM controller controls the first voltage to have different voltage levels during the first time and the second time.

    Abstract: An embodiment disclosed herein provides a sensing unit that senses a touch corresponding to a capacitance formed by a first electrode and a second electrode. The first electrode includes a first driving electrode pattern and a first sensing electrode pattern, the first sensing electrode pattern being disposed in the first driving electrode pattern, the second electrode includes a second driving electrode pattern and a second sensing electrode pattern, the second driving electrode pattern being disposed in the second sensing electrode pattern. A first capacitive coupling is formed corresponding to the first touch electrode and the first sensing electrode, a second capacitive coupling is formed corresponding to the second driving electrode and the second sensing electrode, and a third capacitive coupling is formed corresponding to the first touch electrode and the second sensing electrode.
