Embodiment Construction

[0016] see image 3 , image 3 It is a schematic diagram of an optical axis positioning device 302 used in a liquid lens 300 according to a preferred embodiment of the present invention. The liquid lens 300 includes an encapsulation liquid 308 and a lens liquid 306 .

[0017] In one embodiment, the encapsulation liquid 308 and the lens liquid 306 can be immiscible and non-conductive, and a density of the lens liquid 306 is substantially equal to a density of the encapsulation liquid 308 to avoid □The impact of heavy □ between the liquid, and successfully achieve the shape of the liquid lens.

[0018] The encapsulation fluid 308 can be a first dielectric fluid, and the lens fluid 306 can be a second dielectric fluid. For example, the first dielectric liquid can be an optical oil, and the second dielectric liquid can be a mixture of polyhydric alcohols. Because the refractive index of the encapsulating liquid 308 (ie, optical oil) is relatively large, the combined liquid len...

Abstract

The invention discloses an optical axis positioning device for liquid lenses, which comprises a transparent substrate, a symmetry electrode structure and a transparent insulation layer, wherein the electrode structure can provide an electric field and define an electrode central axis, the insulation layer provides an optical axis positioning structure surrounding the electrode central axis symmetrically. The optical axis of the liquid lens is coaxial with the electrode central axis when the electrode structure not provides an electric field.

Description

technical field [0001] The invention relates to an optical axis orientating device, in particular to an optical axis orientating device for a liquid lens. Background technique [0002] Generally speaking, a liquid lens refers to a lens whose focal length can be adjusted. In the optical system, zoom lenses are roughly divided into two types: mechanical zoom and electronic zoom. The mechanical zoom lens uses the change of the front and rear expansion and contraction of the lens itself to achieve the purpose of zooming. Because the lens of mechanical zoom is too thick and bulky for increasingly thinner and smaller digital cameras or mobile phones with camera functions, many thin and light cameras use electronic zoom lenses. [0003] In the prior art, the electronic zoom technology can use the droplet as a lens, and use mechanisms such as electro-wetting to control the shape and curvature of the droplet, thereby changing the focal length of the droplet. However, if the positi...
