Under-screen camera assembly, camera module, optical lens and manufacturing method thereof

Abstract

An optical lens () includes a first lens () and a second lens component (). A central area of a first surface () of the first lens () protrudes to an object side to form a protrusion portion (), and a top surface () of the protrusion portion () forms an optical area (), and a first structural area () surrounds the protrusion portion (). The second lens component () includes a second lens barrel () and at least one second lens (), and a top of the second lens barrel () is provided with an extension portion () extending inwards, so as to form a light inlet hole () of the second lens component (). Moreover, the topmost second lens () has a third surface () located at the object side, and the third surface () includes an optical area () at center, an inner structural area () surrounding the optical area (), and an outer structural area (). The outer structural area () presses against the bottom surface of the extension portion (), and the inner structural area () is exposed outside the extension portion (). The first lens () is bonded to the second lens component (), and an outer diameter of the first lens () is not greater than a diameter of the light inlet hole (). According to the optical lens (), a diameter of a hole provided on a screen can be reduced without sacrificing the imaging quality. Also disclosed are a camera module, an under-screen camera assembly, a manufacturing method of the optical lens (), and a manufacturing method of the camera module.
