Portable electronic device and camera module set thereof

Abstract

The invention discloses a portable electronic device and a camera module set thereof. The camera module set comprises a flexible circuit board which is adopted as a carrier, a sensor which is arranged on the flexible circuit board and is electrically connected with the flexible circuit board, an aluminum bracket which is arranged on the flexible circuit board and covers the sensor from above, and an infrared cut-off filter; the aluminum bracket comprises a first surface and a second surface which is opposite to the first surface; a photosensitive window which penetrates the first surface and the second surface is formed at the middle of the aluminum bracket; the first surface and the second surface are respectively provided with a first step groove and a second step groove which surround the photosensitive window by one turn; the first step groove is provided with a bottom surface which is opposite to the flexible circuit board; the second step groove is provided with a bearing surface which is parallel to the bottom surface of the first step groove; the bearing surface is separated from the bottom surface by a distance smaller than 0.3 mm; and the infrared cut-off filter is accommodated in the second step groove and abuts against the bearing surface. With the camera module set of the portable electronic device adopted, the miniaturization and high-pixel design of the portable electronic device can be benefitted, and image pickup performance can be improved.

Description

【Technical field】 [0001] The invention relates to a photographable electronic device, in particular to a portable electronic device and a camera module thereof. 【Background technique】 [0002] Portable electronic devices are usually equipped with a camera module for the convenience of taking pictures. For example, a high-end mobile phone has a camera module on the rear shell or the front shell. Traditional camera module brackets usually use plastic brackets, which are adopted by most manufacturers due to their advantages of low cost and easy molding. [0003] However, for high-pixel camera modules, the overall height of the camera module has always been a big problem, because the higher the pixel, the more lenses are required, and the corresponding height is greater. As portable electronic devices become thinner and thinner , which cannot provide a large accommodating space for the camera module, so that the volume of the camera module is greatly limited. Therefore, for a ...

Problems solved by technology

[0003] However, for high-pixel camera modules, the overall height of the camera module has always been a big problem, because the higher the pixel, the more lenses are required, and the corresponding height is greater. As portable electronic devices become thinner and thinner , which cannot provide a large accommodation space for the camera module, so that the volume of the camera module is greatly limited

Therefore, for high-pixel camera modules, if traditional camera modules use high-precision lenses, it is not conducive to the miniaturization design of portable devices.

[0004] In addition, the plastic bracket of the traditional camera module is affected by the material. The wall thickness of the injection molded product is generally only 0.3mm at the thinnest, and because the wall thickness is too thin, the molding is easy to break, deform, and less material. Light leakage is prone to occur on the module

In addition, the high-pixel sensor has very strict requirements on the assembly inclination. The plastic bracket is affected by the material, the fluidity is unstable, and the flatness is difficult to control. It will be a great hidden danger to the image of high-end camera modules.
