Description

Camera module and electronic equipment

cross reference

This application refers to the Chinese Patent Application No. 201910595767.6 filed on July 3, 2019, entitled "Camera Module and Electronic Equipment", which is fully incorporated into this application by reference.

Technical field

This application relates to the field of communication technology, and in particular to a camera module and electronic equipment.

Background technique

The application of camera modules in the field of electronic equipment is becoming more and more extensive, especially in the application of smart mobile terminals. The use of camera modules to take pictures, videos or scans has become an indispensable function in people's life and work. For the structure of the camera module in the related art, please refer to FIG. 1. The camera module 1 includes a lens (LENS) 11 and a light sensor 12. The reflected light generated by the subject is projected onto the light sensor 12 through the optical image generated by the lens 11, converted into an electrical signal by the light sensor 12, converted into a digital image signal through analog-to-digital conversion, and then sent to a digital signal processing chip for processing. The corresponding image. Please refer to FIG. 1, since the camera module 1 in the related technology is used in the application process, the optical information of the subject is directly collected through the lens 11. Therefore, when the camera module 1 is applied, it is necessary to directly face the lens 11 to the subject to collect the light of the subject and transmit it to the light sensor 12 to form a corresponding image. The structure of this camera module 1 poses a big obstacle to the development of the full screen. Full screens have become standard for mid-to-high-end and flagship smart mobile terminals (such as mobile phones, IPAD, etc.). Major manufacturers are striving to increase the proportion of display screens in smart mobile terminals. However, based on the structure of the camera module 1 shown in Figure 1, since the lens 11 of the camera module 1 needs to face the subject directly, the current common smart mobile terminals can only sacrifice industrial design and aesthetics when realizing a full screen. A sea screen or a water drop screen is used to reserve a corresponding installation area for the lens 11. For example, a mobile phone with a sea screen is shown in Figure 2. The display screen used by the mobile phone 2 shown in Figure 2 is a typical sea screen, and the light collection hole 21 reserved on the front of the mobile phone in Figure 2 serves as a lens 11 is reserved for assembly, so that the lens 11 can collect the light of the external subject through the light collection hole 21. For another example, a mobile phone with a water drop screen is shown in FIG. 3. The display screen used by the mobile phone 3 shown in FIG. 3 is a typical water drop screen. In FIG. 32, the light collection hole 31 reserved on the front of the mobile phone serves as the lens 11. The assembly reserved space for the lens 11 to collect the light of the external subject through the light collection hole 31. Since the lens 11 needs to occupy a large installation area, it is necessary to reserve a large assembly area for it on the display screen of the terminal, which is not conducive to the improvement of the screen-to-body ratio, and the overall screen effect is greatly reduced. The degree of satisfaction of the user experience is reduced.
