METHOD FOR APPLYING DRIVING VOLTAGE FOR LIQUID LENS, LIQUID LENS, CAMERA MODULE, AND OPTICAL INSTRUMENT

摘要

A liquid lens according to an embodiment of the present invention comprises: a conductive liquid and a nonconductive liquid which are received in a cavity and have a boundary surface therebetween; and a common electrode and n independent electrodes (n is an integer greater than or equal to two) for controlling the boundary surface, wherein a first driving voltage applied between the common electrode and one of the n independent electrodes is controlled by unit cycle comprising a first sub-cycle and a second sub-cycle, a level of the first driving voltage in the first sub-cycle may be a first voltage, and a level of the first driving voltage in the second sub-cycle may be a second voltage.
