Abstract: A driving circuit with reduced power consumption and a liquid crystal display using the same. The driving circuit includes at least a power circuit, a source driver and a VCOM driver. The power circuit is coupled to a power supply to receive a power signal to generate a positive supply voltage and an inverted power signal. The source driver includes a first source operational amplifier. The first source operational amplifier is powered by the positive supply voltage and a power ground, to couple a positive polarity display voltage to a first terminal of a first display capacitor of a pixel array. The VCOM driver includes a VCOM operational amplifier. The VCOM operational amplifier provides a second terminal of the first display capacitor with a VCOM voltage, and a negative power terminal of the VCOM operational amplifier is coupled to the inverted power signal.

Abstract: A filter for filtering noise generated by a differential signal having a specific wavelength transmitted by a first transmission line and a second transmission line is disclosed. The filter includes a multi-layer substrate, a first microstrip line and a second microstrip line. The first and the second transmission lines and the first and the second microstrip lines are disposed at the multi-layer substrate. In addition, one end of the first microstrip line and one end of the second microstrip line are electrically connected to the first and the second transmission lines, respectively, by passing through the vias, and the other end is in a floating state. The impedances of the first and the second microstrip lines match the impedances of the first and the second transmission lines, respectively. Thus, the first and the second microstrip lines may filter the noise generated by the differential signal having the specific wavelength.
