Problems solved by technology

[0003] Multi-functionality and thinness are one of the main development trends of many smart devices at present. However, in the case of continuous optimization of camera module functions, a bottleneck problem has emerged: the traditional structure of camera modules can no longer meet the requirements of lightness and thinness.
Although the blue glass is relatively better than the infrared cut filter in terms of optical effect, the processing technology of the flake blue glass at that time was difficult and the processing efficiency was low, so the actual application rate of the blue glass in the camera module was low.

Abstract

The invention discloses a light filtering member, a photographing module, a manufacture method for the light filtering member thereof and an application of the photographing module. The light filtering member is applied to the photographing module and comprises a curved surface main body. The curved surface main body can reflect and filter the light in order to replace a lens of a lens camera of the photographing module.

Description

technical field [0001] The present invention relates to the field of camera modules, and further relates to a filter element, a lens, a camera module and a manufacturing method and application thereof. Background technique [0002] With the development of various smart devices, the scope of application of camera modules is becoming wider and wider, and in turn, the functions and structures of camera modules also affect smart devices. [0003] Multi-functionality and thinness are one of the main development trends of many smart devices at present. However, in the case of continuous optimization of camera module functions, a bottleneck problem has emerged: the traditional structure of camera modules can no longer meet the requirements of thinness. Therefore, the thickness and volume of the camera module have become an important factor limiting the realization of smart devices. For example, the thickness of a mobile phone largely depends on the thickness of the camera module. ...
