Abstract

At least one diagonal plane is formed along the edge of an optical filter, and an included angle is formed between the diagonal plane and one surface of the optical filter. A mobile phone camera shooting module set comprises a support, a camera shooting module and the optical filter. A containing groove is formed in the surface of the support, a light permeating hole is formed in the center of the bottom of the containing groove, and the side wall of the containing groove is coated by a first glue layer. The camera shooting module is arranged on the surface of the support and covers the containing groove, and an optical axis of the camera shooting module passes through the center of the light permeating hole. The optical filter is contained in the containing groove and covers the light permeating hole, the optical filter is connected with the first glue layer in an adhesive mode, and a gap is formed between the diagonal plane of the optical filter and the side wall of the containing groove. The gap can contain excessive glue of the first glue layer, and can prevent glue from overflowing to the surface of the optical filter when the optical filter is bonded with the camera shooting module, a light path of a light ray cannot be affected, and the image effect of the camera shooting module set cannot be affected. The invention further provides a manufacturing method of the optical filter.

Description

technical field [0001] The invention relates to the field of mobile phone camera, in particular to an optical filter, a mobile phone camera module containing the optical filter and a manufacturing method of the optical filter. Background technique [0002] Currently, a mobile phone image module is equipped with a filter, which is used to filter infrared light and ultraviolet light that cannot be seen by the naked eye but can be reflected by the lens. This kind of filter can improve some bad problems of the mobile phone camera module, such as chromatic aberration, shadow, ghost, blur, glare, etc., and can enhance the transmittance of light entering the module lens, and improve the image effect of the mobile phone module. When assembling the mobile phone camera module, the optical filter needs to be glued into the VCM voice coil motor bracket with glue. During the assembly process, it is often necessary to squeeze the optical filter so that the optical filter can be firmly bo...
