Photosensitive component with anti-shake function and corresponding camera module

Abstract

The invention relates to a photosensitive component with an anti-shake function. The photosensitive component comprises a photosensitive chip; a middle seat formed through a semiconductor process, wherein the back face of the photosensitive chip abuts against and is fixed to the upper surface of the middle seat, and the middle seat is provided with a middle seat contact located on the outer side of the photosensitive component; a base comprising a bottom plate and a side wall, wherein the periphery of the bottom plate extends upwards to form the side wall, the side wall surrounds the middle seat, a gap is formed between the side wall and the side face of the middle seat, the top face of the side wall is provided with a base contact, and the middle base contact is electrically connected with the base contact based on a routing technology; an elastic supporting piece used for elastically connecting the side wall and the middle seat; and a driving element arranged between the middle seat and the base and used for driving the middle seat to move relative to the base in the direction parallel to the photosensitive surface. The invention also provides a corresponding camera module. According to the invention, the anti-shake function of the photosensitive component can be realized with low space cost.

Description

technical field [0001] The invention relates to the technical field of camera modules, in particular, the invention relates to a photosensitive component with an anti-shake function and a corresponding camera module. Background technique [0002] With the popularization of mobile electronic devices, related technologies of camera modules used in mobile electronic devices to help users acquire images (such as video or images) have developed rapidly and improved rapidly, and in recent years, camera modules Groups have been widely used in many fields such as medical treatment, security, industrial production and so on. Currently, in the field of consumer electronics (such as the field of mobile phones), the optical image stabilization function has become one of the common functions of camera modules. When an electronic device (such as a smart phone) takes pictures, it is inevitable that shaking will occur due to various reasons. For example, when holding a smartphone for shoo...

Problems solved by technology

However, the structure of the gimbal occupies a large volume, which will increase the thickness of the mobile phone, which is not in line with the current trend of thinner and lighter smart phones

Moreover, due to the large size of the gimbal, for smart phones whose internal space is extremely precious, the use of this gimbal-based anti-shake solution may significantly increase the design difficulty of the mobile phone and occupy the space of other modules (such as batteries)
