▎ 摘　　要

NOVELTY - The electrochromic aperture has a first transparent substrate (71), a first transparent conductive layer (72), an ion storage layer (73), an ion transfer layer (74), an electrochromic layer (75), a second transparent conductive layer (76), and a second transparent substrate (77) all sequentially stacked. The voltage at which the electrochromic aperture starts to brighten gradually increases from the inside to the outside, or the voltage at which the electrochromic aperture starts to become dark gradually decreases from the inside to the outside. USE - Electrochromic aperture for aperture lens combination of lens module (all claimed) used in mobile terminals such as mobile phones and tablet computers. ADVANTAGE - The thickness of the electrochromic layer is gradually increased from the inside to outside so as to make the aperture from inside to outside with different color range, thus realizing larger difference of the aperture level adjustment. The aperture can be flexible and bendable so as to design the aperture as a curved surface structure, thus combining with achromatic lens combination, and thinning the lens module. The electrochromic aperture has different color changing ranges from the inside to the outside, and can realize a more different aperture series adjustment, and meet the requirements of various shooting scenes. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of multi-level regulation of electrochromic aperture for aperture lens combination of lens module. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a cross-sectional structure of an electrochromic aperture.
