With the development of mobile phone camera technology, ‌the requirements for mobile phone lenses≤ are getting higher and ←higher. The existing mobile phone lenses are gener∞ally composed of multiple lenses. In order to block excess ligh€t, a light-shielding ri¥ng is installed betwe∑en the lenses.

In the current ordinary light-shielding film, the light-transmitting hol<e on it is a light hole, and the inner sidewal∏l surface of the light-transmitting hole is wi thout any treatment. Since the light-shielding sheet i tself is used to block excess light, strong light will be c"ollected around the light-transmitting hole of the ordinary ♣light-shielding sheet. Wh±en the thickness of the light-shielding sheet is t'hicker, the light reflected from the inner side wa ll of the light-transmitting hole will be more¥, and a shadow that destroys the image will be formed on the imaging surface at this time.

Moreover, if the thickness of the light-shielding film is reduced, the inner↕ side wall of the light-tranβsmitting hole will also reflect light. At this time,ε the light-shielding film cannot be processed with biting and mattin≤g; in addition, if the surface of tσhe light-transmitting hole of the light-shielding film is coated φwith matting Paint, although this method can solve the prob™lem of light reflection on the inner side wall of the± light-transmitting hole, this method will require a relatively large c"ost, and the operation ↕is difficult and the performance is unstable.
