Problems solved by technology

[0003] However, as the pixels become larger and larger, the size of the photosensitive area of ​​the photosensitive chip used becomes larger, resulting in a larger lens. A larger lens means more light needs to be collected, so the diameter of the light hole needs to be larger. Synchronization results in larger filter size
Due to the large size of the filter, and the filter is only connected to the supporting platform through a circle around its edge, and there is no supporting part in the middle of the filter, when it is used for mechanical reliability tests such as dropping, it is easy to cause the filter chipping in the middle

Abstract

A camera module comprises a supporting seat and an optical filter, the supporting seat is provided with a light through hole, the optical filter is fixed in the light through hole, a transparent supporting portion is further arranged in the light through hole, the transparent supporting portion is fixed in the light through hole, the optical filter is located on one side of the transparent supporting portion, and the transparent supporting portion is used for supporting the optical filter. The bottom of the optical filter can be prevented from being broken when the camera module is subjected to mechanical reliability experiments such as falling. The invention also relates to a mobile terminal.

Description

technical field [0001] The invention relates to the technical field of cameras, in particular to a camera module and a mobile terminal. Background technique [0002] At present, the conventional support seat (Holder) used by the camera module will open a light hole in the middle of the support seat. There is a bearing platform on the wall of the light hole. Above, the light collected by the lens passes through the light hole of the support base after being filtered by the filter, and shines on the photosensitive chip, so that the photosensitive chip can collect the light, perform photoelectric conversion, and finally output the photo. [0003] However, as the pixels become larger and larger, the size of the photosensitive area of ​​the photosensitive chip used becomes larger, resulting in a larger lens. A larger lens means more light needs to be collected, so the diameter of the light hole needs to be larger. Synchronization results in larger filter sizes. Due to the large...
