A liquid lens, a processing method thereof, and an imaging module

Abstract

The present application relates to the technical field of imaging module manufacturing, and provides a liquid lens, a processing method thereof, and an imaging module. The liquid lens comprises at least one substrate; the substrate is provided with N substrate through holes, N is a natural number greater than or equal to 1; each substrate through hole is provided with a driving portion connected to a lens driving circuit; and the substrate is further provided with a first a sealing layer and a second sealing layer, the first sealing layer, the second sealing layer and the substrate through holes form a lens cavity, the lens cavity is filled with a liquid medium; and each substrate through hole is provided with an insulation layer for isolating the liquid medium from the driving portion. Byadopting the embodiments of the present application, the product size can be flexibly adjusted, processed, and assembled more conveniently; automatic mass production can be realized, thus forming benefits to reduce costs.

Description

technical field [0001] The present application relates to the technical field of imaging equipment manufacturing, in particular to a liquid lens, a processing method thereof, and an imaging module. Background technique [0002] With the rapid development of terminal services, simple and portable camera equipment is becoming more and more popular. With the development of technology, various ultra-thin focusing lenses gradually appear, such as zoom cameras with voice coil focus motors and mechanical zoom lenses for mobile phones. [0003] The inventors have found that the prior art has at least the following problems: the small size of the voice coil focusing device makes assembly inconvenient, and the cost of the entire camera module is high; the mechanical zoom lens is large in size and difficult to miniaturize and integrate; The electrowetting liquid lens is too large in size and not suitable for macro imaging, and it is not easy to automate mass processing; the published ...
