Problems solved by technology

In this solution, the moving part of the lens is limited by the upper and lower springs. The selection of the spring determines the displacement. The lower the k value of the spring, the faster the lens moves, but it may overshoot, and the spring is more easily damaged. A higher k value requires a larger current to generate more force to push the lens. In addition, the change of spring k value caused by process deviation will affect the stability of the system.

Abstract

The invention provides an optical anti-shake implementation method of a camera module. The camera module comprises a lens module, an image sensor chip serving as a rotor and a supporting part servingas a stator. The bonding pad of the image sensor chip is electrically connected to the bonding pad of the support part through a plurality of suspension structures. The suspension structure plays a role in supporting the image sensor chip in a suspended manner and electrically connecting the image sensor chip.

Description

technical field [0001] The invention relates to the technical field of image sensors, in particular to a method for realizing optical anti-shake of a camera module. Background technique [0002] OIS (Optical Image Stabilization) uses the floating lens of the lens to correct the "optical axis offset". The compensated displacement is then compensated by the compensation lens group according to the shake direction and displacement of the lens, so as to effectively overcome the image blur caused by the vibration of the camera. This anti-shake technology has relatively high requirements for lens design and manufacture, and the cost is relatively high. [0003] Traditional smartphones usually achieve anti-shake by adjusting the lens, and adopt a VCM (Voice Coil Motor) structure. The main principle is to control the pull of the spring by changing the DC current of the inner coil of the voice coil motor in a permanent magnetic field. Extended position, so as to drive up and down m...
