SELF-HEATING LIQUID LENS AND SELF-HEATING METHODS FOR THE SAME

Abstract:

A liquid lens comprising: a lens body including a cavity, a control electrode, and a common electrode; a first liquid disposed within the cavity and in electrical communication with the common electrode; a second liquid disposed within the cavity; an insulating layer in contact with the first liquid and the second liquid and separating the first liquid and the second liquid from the control electrode; and a driver driving a voltage differential across the common electrode and the control electrode, with the first liquid resisting current flow between the common electrode and the control electrode and thereby raising a temperature of the first liquid from a current temperature to a predetermined temperature, which is higher than the current temperature. The driver raises the temperature of the first liquid from the current temperature to the predetermined temperature by increasing a frequency of a voltage waveform of the voltage differential.
