The utility model, which is related to be coated with purple light reflectance coating, camera lens on a kind of camera lens module of improvement purple boundary problem, including chip, IRCF, camera lens and protective glass, the protective glass, is coated with AR films.Then technics comparing is simple and ripe for plated film on protective glass or IRCF, and effect is more preferable；Plate purple light reflectance coating to reflect due to existing, other ghost risks are produced so existing；And use and purple light absorbent material is coated on protective glass or IRCF, then without this risk.
Description
Technical field
The utility model is related to a kind of camera lens module, more particularly to a kind of camera lens module of improvement purple boundary problem.
Background technology
In recent years, Mobile Industry there occurs rapid development, and in order to improve portability, mobile phone production firm is always in opponent
The lightening of machine is improved.Camera lens module wherein in mobile phone occupies certain space, in the current intelligent machine epoch, to the greatest extent
Pipe periscopic Zoom optic lens module can reducing thickness, but the volume of periscopic Zoom optic lens module is particularly thick
Larger space is still occupied in terms of degree.The age of an inch of land is an inch of gold is laid out in this cell phone components, the slimming of whole camera lens module is
Inexorable trend.
In the current intelligent machine epoch, although periscopic zoom can reducing thickness, the volume of optics module still occupies
Larger space.The age of an inch of land is an inch of gold is laid out in this cell phone components, the slimming of whole camera lens module is inexorable trend.In addition
With the realization of high memory configurations, people are also more urgent to high-resolution demand.Existing sensor (sensor) is set
In zoom lens group dead astern, sensor (sensor) length and width size influences the thickness of mobile phone；The thin type demand of mobile phone, makes
Obtain Sensor length and width size-constrained, it is impossible to realize the design of higher pixel.
Traditional camera module structure is probably made up of following 4 part：Cover glass (protective glass), Lens (mirrors
Head), IRCF (cutoff filter), Sensor (chip).Current camera module aperture is increasing, along with, figure
The purple boundary problem of picture is also increasingly severe.
The light of different wave length is different due to refractive index, and feux rouges refractive index is minimum, and purple light refractive index is maximum, when light passes through
Dispersion can be formed after camera lens；Purple light is maximum due to refractive index, performance most substantially, so as to form purple boundary.
Traditional improvement purple boundary method mainly has two kinds：(hardware is improved by the dispersion correction of camera lens plated film and camera lens
Mode)；(software mode) is corrected by the software later stage.
It is all traditionally to be carried out generally by the plated film of camera lens because the basic reason for causing purple boundary is the dispersion of camera lens
Improve, usually increase the reflection of purple light, reduce the purple light energy for being injected into chip, so that reaching improves the purpose of purple boundary.
This namely why high-end camera lens all can slightly general purple light.
Current camera lens plated film mainly has following shortcoming：
Because eyeglass is usually to be made up of convex lens or concavees lens, surface is usually curved surface, so coating process ratio
More complicated and plated film scattered error is also not easily controlled, and this is also the expensive one of reason of high-end camera lens；
Current eyeglass is typically made up of PC plastics, and the requirement to coating process is higher；
By reflection of the plated film mode generally by increase purple light, but it is due to the increase of reflection, can increases to form ghost
The risk of shadow.
Utility model content
The purpose of this utility model is the serious defect of purple boundary in order to solve the problems, such as image after existing lens shooting and carried
Improve the camera lens module of purple boundary problem for a kind of.
To achieve these goals, the utility model uses following technical scheme：
It is a kind of to improve the camera lens module of purple boundary problem, including chip, IRCF, camera lens and protective glass, the protective glass
On be coated with purple light reflectance coating, camera lens and be coated with AR films.
It is a kind of to improve the camera lens module of purple boundary problem, including chip, IRCF, camera lens and protective glass, the protective glass
On be coated with purple light absorbing film, camera lens and be coated with AR films.
A kind of improve is plated on the camera lens module of purple boundary problem, including chip, IRCF, camera lens and protective glass, the IRCF
Have and AR films are coated with AR films and purple light absorbing film, camera lens.
The beneficial effects of the utility model are：Then technics comparing is simple and ripe for plated film on protective glass or IRCF,
Effect is more preferable；Plate purple light reflectance coating to reflect due to existing, other ghost risks are produced so existing；And use in protective glass or
Purple light absorbent material is coated on person IRCF, then without this risk.

Embodiment
With reference to embodiment, the utility model will be further described.In the utility model involved device,
Connection structure and method, if being device well known in the art, connection structure and method without refering in particular to.
Embodiment 1
Reference picture 1, it is a kind of to improve the camera lens module of purple boundary problem, including chip 1, IRCF2, camera lens 3 and protective glass 4,
It is coated with the protective glass 4 on purple light reflectance coating 5, camera lens 3 and is coated with AR films 6.
Embodiment 2
Reference picture 2, it is a kind of to improve the camera lens module of purple boundary problem, including chip 1, IRCF2, camera lens 3 and protective glass 4,
It is coated with the protective glass 4 on purple light absorbing film 7, camera lens 3 and is coated with AR films 6.
Embodiment 3
Reference picture 3, it is a kind of to improve the camera lens module of purple boundary problem, including chip 1, IRCF2, camera lens 3 and protective glass 4,
It is coated with the IRCF2 on AR films 6 and purple light absorbing film 7, camera lens 3 and is coated with AR films 6.
Then technics comparing is simple and ripe for plated film on protective glass or IRCF, and effect is more preferable；Plate purple light reflectance coating by
In there is reflection, other ghost risks are produced so existing；And use and purple light absorbability is coated on protective glass or IRCF
Material, then without this risk.
It is described above, only it is preferred embodiment of the present utility model, not the utility model is imposed any restrictions, every
