Abstract

This application provides an electronic device. An opening is disposed on a support plate of a middle frame, and a camera module is mounted corresponding to the opening. At least a part of the thickness of the dimming conversion assembly of the camera module extends into the opening, the part of the thickness of the dimming conversion assembly does not occupy a mounting space between the middle frame and a rear cover (a display panel), and a thickness of the whole machine can be reduced, thereby facilitating lightening and thinning of the electronic device. The inner concave portion is disposed on at least a part of an area of a circumferential edge of the dimming conversion assembly, and the edge of the inner concave portion contracts in the edge of the lens assembly.
