Abstract
A liquid lens includes a first plate including a cavity in which a conductive liquid and a non-conductive liquid are disposed; a first electrode placed under the first plate; a second electrode placed on the first plate; a second plate on the second electrode; and a third plate under the first electrode, wherein a region of the second plate, which is disposed on the conductive liquid, includes a first region having a first thickness and including an optical axis, and a second region extending from the first region and having a second thickness, and the first thickness is greater than the second thickness.
Claims20
A liquid lens, comprising:
- a first plate comprising a cavity in which a conductive liquid and a non-conductive liquid are disposed;
- a first electrode disposed under the first plate;
- a second electrode disposed on the first plate;
- a second plate disposed on the second electrode;
- and
- a third plate disposed under the first electrode,
- wherein a region of the second plate, which is disposed on the conductive liquid, comprises a first region having a first thickness and encompassing an optical axis, and a second region extending from the first region and having a second thickness, and
- wherein the first thickness is larger than the second thickness.
A liquid lens, comprising:
- a first plate comprising a cavity in which a conductive liquid and a non-conductive liquid are disposed;
- a first electrode disposed under the first plate;
- a second electrode disposed on the first plate;
- a second plate disposed on the second electrode;
- and
- a third plate disposed under the first electrode,
- wherein a thickness of a region of the second plate, which is disposed on the conductive liquid, in a direction parallel to an optical axis is smaller than a thickness of a region of the second plate, which is coupled to the first plate, in a direction parallel to the optical axis.
A liquid lens, comprising:
- a second plate and a third plate, the second plate and the third plate being transparent;
- a first plate disposed between the second plate and the third plate, the first plate comprising an open region having a predetermined inclined surface;
- a cavity defined by the second plate, the third plate, and the open region;
- and
- two liquids charged in the cavity, the two liquids having different properties from each other,
- wherein the second plate comprises:
- a bonding region bonded to the first plate;
- a center region formed corresponding to the open region;
- and
- a peripheral region spaced apart from the first plate, the peripheral region being located between the bonding region and the center region, and
- wherein a thickness of the center region is larger than a thickness of the peripheral region so that a degree of warping of the center region in response to a change in temperature is small.
