Abstract
A liquid lens system includes a liquid lens and a heating device disposed in, on, or near the liquid lens. The liquid lens system can include a temperature sensor. The heating device can be responsive to a temperature signal generated by the temperature sensor. A camera module can include the liquid lens system. A method of operating a liquid lens includes detecting a temperature of the liquid lens and heating the liquid lens in response to the detected temperature. Various embodiments disclosed herein can reduce, impede, or prevent crosstalk between components of the liquid lens, or the effects thereof.
Claims20
A liquid lens comprising:
- a chamber;
- a first fluid contained in the chamber;
- a second fluid contained in the chamber;
- a fluid interface between the first fluid and the second fluid;
- one or more first electrodes insulated from the first and second fluids;
- a second electrode in electrical communication with the first fluid, wherein a position of the fluid interface is based at least in part on voltage applied between the first and second electrodes;
- a temperature sensor;
- a heater;
- and
- a layer of conductive material that is segmented such that the heater, the temperature sensor, and the portion of the one or more first electrodes are disposed in the layer of conductive material with insulating barriers separating the heater, the temperature sensor, and the one or more first electrodes,
- wherein the temperature sensor is coplanar with at least a portion of one of (a) the one or more first electrodes or (b) the second electrode;
- and
- wherein the heater is coplanar with at least a portion of one of (a) the one or more first electrodes or (b) the second electrode.
A liquid lens comprising:
- a chamber;
- a first fluid contained in the chamber;
- a second fluid contained in the chamber;
- a fluid interface between the first fluid and the second fluid;
- one or more first electrodes insulated from the first and second fluids;
- a second electrode in electrical communication with the first fluid, wherein a position of the fluid interface is based at least in part on voltage applied between the first and second electrodes;
- an intermediate layer comprising a tapered cavity having a wide end and a narrow end;
- a first outer layer bonded to the intermediate layer at the wide end of the tapered cavity;
- a second outer layer bonded to the intermediate layer at the narrow end of the tapered cavity, wherein each of the heater, the temperature sensor, and the portion of the one or more first electrodes is disposed between the intermediate layer and the second outer layer;
- a temperature sensor;
- and
- a heater;
- wherein the temperature sensor is coplanar with at least a portion of one of (a) the one or more first electrodes or (b) the second electrode;
- and
- wherein the heater is coplanar with at least a portion of one of (a) the one or more first electrodes or (b) the second electrode.
