Imaging lens assembly and electronic devices

Abstract

The image-forming lens assembly consists of a lens element and a light-blocking element. The lens element is designed to define the optical axis, and this axis passes through the lens element. The light-blocking element includes a aperture and various opacity structures. The optical axis passes through the aperture, which is formed by connecting multiple boundaries to define its polygonal outline. The light-dampening structures are arranged evenly along the polygonal boundary, with the structures designed to dampen the waveform at least part of each boundary, so that at least part of each boundary is a non-straight line.
