Abstract: A method of controlling electrodes of a pixel in a plasma display panel. The method includes applying a first voltage to a first electrode of the pixel during a sustain discharge involving the first electrode, and applying a second voltage to a second electrode of the pixel. The first voltage and the second voltage have a relationship that encourages the sustain discharge to extend to the second electrode.

Abstract: A touch pad and a position detecting circuit and method thereof are provided. The touch pad uses a waveform generator to generate an input signal; the input signal is capable of gradually moving a position of a zero voltage on the sensing pad in a predetermined direction. The touch pad also uses the zero voltage detector to detect when a zero voltage of the sensing signal of the sensing pen occurs so as to determine the position of the sensing pen on the sensing pad. Hence, the analog-to-digital converter is not required. Therefore, the resolution can be easily expanded, and the cost, the preciseness, and the specification can be easily controlled.

Abstract: A low-power-consumption source driver for a liquid crystal display is provided. More than one middle voltage level for the level shifter and the output buffer is provided, in addition to the power supply voltage level VDD and the ground level GND, to provide different voltage levels for image data of different polarities. Hence, amplitude of the operational voltage of the level shifters and the analog circuits with different polarities can be reduced. It also can reduce the amplitude of the operational voltage of the level shifter and can reduce significantly the dynamic power consumption of the level shifter and the DAC. Because the voltage amplitude of the circuit is reduced and a low-voltage tolerated device can be used, so that the present invention can further reduce the cost of the circuit.
