Embodiment Construction

[0042] With the advancement of technology, the pixel requirements of the camera modules of smartphones or tablets are getting higher and higher. Currently, the above-mentioned electronic devices use camera modules with about 12 million pixels to 40 million pixels. This type of optical module is manufactured using a direct package (Chip on Board, COB) process, which needs to electrically connect the photosensitive element and the substrate through wire bonding. However, since the wire bonding takes up a lot of space, the design of the wire bonding will increase the size (especially in height) of the optical module, thus making it difficult to reduce the volume of the optical module. The optical module that electrically connects the photosensitive element and the substrate through other methods will be described below, which has a smaller size and can be applied to thinner or full-screen electronic devices.

Abstract

The invention provides an optical module. The optical module comprises a substrate, a photosensitive element, a lens holder and a conductive circuit, wherein the substrate comprises a first connecting pad. The photosensitive element is disposed on the substrate. The photosensitive element has a first surface and a second surface opposite to the first surface and facing the substrate. The photosensitive element comprises a second connecting pad located on the first surface and a photosensitive area. The lens holder is disposed on the substrate and surrounds the photosensitive element. The lens frame comprises an inner surface, the inner surface comprises a first part and a second part, the first part corresponds to the first connecting pad of the substrate, and the second part corresponds to the second connecting pad of the photosensitive element. The conductive circuit is arranged on the inner surface of the lens frame and extends to the first part and the second part, and therefore the first connecting pad is electrically connected with the second connecting pad through the conductive circuit.

Description

technical field [0001] The present invention relates to an optical module, in particular to an optical module with a smaller size. Background technique [0002] Common portable electronic devices include notebook computers, smartphones, or tablet PCs, etc., because the above-mentioned portable electronic devices have the advantage of being easy to carry around to facilitate users to send and receive information in real time , has become an indispensable tool for modern people. On the other hand, in order to allow users to obtain images in real time, optical modules with lenses have gradually become the standard equipment of the above-mentioned portable electronic devices. However, how to configure such an optical module in a portable electronic device has become one of the research topics that many manufacturers have invested in. [0003] For example, most of the current smartphones tend to be full-screen. The optical modules of existing smartphones, such as the camera mod...
