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.

Abstract: A display device integrated with a touch screen panel, and a method of driving the same, can prevent parasitic capacitance that would otherwise increase the load during a touch operation, lower the accuracy of touch sensing, or make touch sensing impossible. The display device includes data lines, gate lines, and a plurality of electrodes spaced apart from each other. A common voltage is applied to the electrodes in a display driving mode and a touch drive signal is applied to one or more of the electrodes in a touch driving mode. A data voltage is applied to the data lines in the display driving mode. A scan signal is supplied sequentially to the gate lines in the display driving mode and the touch drive signal or a signal corresponding to the touch drive signal is applied to one or more of the gate lines in the touch driving mode.
