摘要： The present invention relates to a variable focus lens. The variable focus lens comprises a fluid chamber having a protrusion formed along one opened end thereof. The fluid chamber is cylindrically shaped to house first and second non-miscible fluids therein, and the first and second fluids have different refractive indices. A transparent element hermetically is coupled with the opened end of the chamber with a predetermined gap from the protrusion of the chamber. A first electrode is disposed inside the chamber to act on the first fluid, and a second electrode is insulated from the first electrode. The variable focus lens can be easily fabricated to prevent bubble formation with the protrusion formed at the opened end of the chamber.

摘要： A circuit for generating a step-up voltage, in which it can reduce ripples. The circuit includes a high voltage transfer switch, a high voltage switching unit that pumps a high voltage in response to a clock signal and switches the high voltage transfer switch, a high voltage switching controller, which compares a feedback voltage generated by dividing an output signal of the high voltage transfer switch and a variable reference voltage, generates an internal clock signal using the comparison result and the clock signal, and controls the switching of the high voltage transfer switch in response to the comparison result, and a step-up voltage generator that pumps the high voltage in response to the internal clock signal and a plurality of step-up reference voltages and generates an internal step-up voltage. The high voltage transfer switch outputs the internal step-up voltage in response to the output signal of the high voltage switching unit.
