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

Abstract

The invention relates to an optical lens. The optical lens comprises a first lens piece and a second lens part, the central area of the first surface of the first lens piece protrudes towards the object side to form a protruding part, the top surface of the first lens forms an optical area, and the first structure area surrounds the protruding part. The second lens part comprises a second lens barrel and at least one second lens piece, the top of the second lens barrel is provided with an extending part formed by extending inwards, the extending part forms a light inlet hole of the second lenspart, and the second lens piece at the topmost part is provided with a third surface located on the object side, and comprises an optical area located in the center, an inner structural area and an outer structural area, the inner structural area and the outer structural area surround the optical area, the outer structural area leans against the bottom surface of the extending part, and the innerstructural area is exposed outside the extending part. The first lens piece is bonded with the second lens part, and the outer diameter of the first lens piece is not larger than the aperture of thelight inlet hole. The invention further provides a corresponding camera shooting module, an under-screen camera shooting assembly and a corresponding manufacturing method. The aperture of the screen opening can be reduced on the premise of not sacrificing the imaging quality.

Description

technical field [0001] The invention relates to the technical field of camera modules, in particular, the invention relates to an under-display camera module, a corresponding camera module, an optical lens and a manufacturing method thereof. Background technique [0002] With the popularization of mobile electronic devices, related technologies of camera modules used in mobile electronic devices to help users acquire images (such as video or images) have developed rapidly and improved rapidly, and in recent years, camera modules Groups have been widely used in many fields such as medical treatment, security, industrial production and so on. [0003] In the field of consumer electronics, such as the field of smart phones, the front camera module is an indispensable component. The front camera module is usually arranged on the same side of the display screen, and is used for Selfie and other functions of the user. However, as the screen-to-body ratio increases, higher and hi...

Problems solved by technology

However, the size of the head of the current camera module is more than 3mm. Putting the head of the camera module into the hole will make the size of the screen opening large enough, and the camera module is placed behind the screen. To meet the requirements of the field of view, the side wall of the screen opening cannot affect the camera module to collect light, so the same opening should be relatively large, at least 4.5mm or more

Such a large opening will lead to poor display effect of the screen and affect the user experience of the screen
