Abstract
A liquid lens can be coupled to ground, such as to impede charge from building up in the liquid lens during operation thereof. For example, an electrode that is in electrical communication with a conductive fluid of the liquid lens can be coupled to ground. A switch can be used to selectively couple the liquid lens to ground, such as for discharging the liquid lens. An electrode can be selectively coupled to ground and to driving signals using a switch. In some cases, drive signals can be provided to electrodes other than the grounded electrode for driving the liquid lens. In some cases, the liquid lens can be driven using feedback control based on one or more measured parameters indicative capacitance between a fluid and one or more electrodes in the liquid lens.
