Abstract
A lens module comprises a lens barrel, a lens group located in the lens barrel and an anti-dazzling screen group located in the lens barrel; the lens group comprises a plurality of lenses sequentially arranged from the object side to the image side, and the anti-dazzling screen group comprises a plurality of anti-dazzling screens; each anti-dazzling screen is annular and comprises a first surface and a second surface opposite to the first surface, the anti-dazzling screen further comprises an inclined face, the inclined face is connected with the first surface and the second surface, the inner diameter of the portion, adjacent to the first surface, of the anti-dazzling screen is larger than the inner diameter of the portion, adjacent to the second surface, of the anti-dazzling screen, the first surface, the second surface and the inclined face are all antireflection surfaces. The plurality of anti-dazzling screens are located among the plurality of lenses, and the inclined faces of the anti-dazzling screens face the lenses. The invention further relates to an anti-dazzling screen and an electronic device.
Description
technical field [0001] The invention relates to a shading sheet, a lens module and an electronic device. Background technique [0002] The optical characteristics of the lens module are easily affected by errors or defects of the lens. In the prior art, a light-shielding sheet is often used to block part of the stray light to avoid the occurrence of light spots. Due to the high reflectivity of the PET layer on the inner wall of the prior art light-shielding sheet, it is easy to cause stray light and affect the imaging quality; in addition, the tip of the light hole of the traditional plastic one-piece lens barrel is also prone to reflection due to the limitation of the process. stray light. Contents of the invention [0003] In view of this, it is necessary to provide a shading sheet capable of reducing glare. [0004] It is also necessary to provide a lens module including the above-mentioned shading sheet. [0005] It is also necessary to provide an electronic device ...
