    摘要： A method is provided. A first voltage is applied to a first set of column electrodes within a touch panel during a first interval, and a second voltage is applied to a second set of column electrodes within the touch panel during the first interval. The first and second sets of electrodes are adjacent to one another, and the second voltage has the opposite polarity of the first voltage. During the first interval, a first measurement signal is received from a set of row electrodes in the touch panel, and the first measurement signal is integrated to generate a first integrated signal. The first voltage is applied to the second set of column electrodes within the touch panel during a second interval, and the second voltage is applied to the first set of column electrodes within the touch panel during the second interval. During the second interval, a second measurement signal is received from the set of row electrodes in the touch panel, and the second measurement signal is integrated to generate a second integrated signal. Then, the first and second integrated signals are combined to generate an output signal.

    摘要： A liquid lens driver 10 has DC-DC converter 12, oscillator 14, pulse width modulator 16, and control logic circuit 18. The output buffer circuit 30 divides converter output voltage Vs of a prescribed amplitude (voltage level), input as the power source voltage, into bipolar, that is, positive/negative, output voltages Out-A, Out-B for output, and, corresponding to the H/L level of PWM signal CPWM, it turns ON/OFF the two output voltages Out-A, Out-B. In this way, from liquid lens driver 10, pulse width modulation (PWM) output voltages Out-A, Out-B are applied as driving voltage VL on electrodes 104, 108 of liquid lens 100.
