Abstract

The invention relates to a film structure and a lens barrel including the same. The film structure includes: an anti-reflection film layer comprising a high refractive index material layer and a low refractive index material layer which are alternatively stacked; and a first waterproof film layer, wherein the first waterproof film layer is arranged on an outer side of the anti-reflection film layer in the direction away from the lens barrel. The film structure is plated on a surface of the lens barrel, is beneficial to reducing the reflection intensity of the surface of the lens barrel, and can prevent abrasion and pollution, so that it is effectively ensured that a camera module assembled by the lens barrel having the film structure has good imaging quality.

Description

technical field [0001] The invention belongs to the technical field of lens barrel coating, and in particular relates to a film layer structure for reducing the reflection intensity of the lens barrel surface. Background technique [0002] With the rapid development of the mobile phone industry, the mobile phone camera has developed from a single camera to a triple camera. The powerful camera function has become an important selling point of mobile phones, and the market demand is huge. However, the market’s requirements for camera performance are getting higher and higher. With traditional lenses, the reflection of light on the surface of the lens barrel will inevitably cause certain interference to the optical system, resulting in poor imaging quality. In order to increase the visual consistency of the panel, it is necessary to coat the surface of the lens barrel. In the prior art, the film layer coated on the lens barrel has poor performance in reducing the surface refle...
