Description

Zoom lens and camera module
Technical field
The present invention relates to camera module group lens technical field, more particularly, relate to a kind of zoom lens and camera module.
Background technology
Varifocal camera module is widely used in the electronic equipment such as mobile phone, notebook computer, and zoom lens is the focus that those skilled in the art study as the vitals of varifocal camera module always.
The zoom lens control device of varifocal camera module generally comprises lens(camera lens) and VCM(Voice CoilMotor, voice coil motor).Lens forms primarily of multi-disc optical lens, lens is embedded in VCM, VCM can drive lens to move along optical axis, lens being subjected to displacement (even if the focal length of zoom lens changes) relative to the sensitive chip of camera module, realizing the blur-free imaging when not changing shooting distance.
But find in actual production and application process, the reliability of existing zoom lens control device is poor, thickness low LCL is thin, and production cost is higher, hinders the wide popularization and application of zoom lens control device.
Zoom lens control device of the prior art drives lens group to move by VCM stretching motion, produces relative displacement, realize zoom function with sensitive chip.VCM is a kind of electromagnetic and mechanical device, and structure is more complicated, and assembly is more, therefore inherently fragile, and the vibrations of VCM motion generation and friction can make plant failure rate rise, and assembly is easily aging, serviceable life declines, and these reliabilities all causing conventional zoom device to use are lower.VCM is not used to produce Zoom effect in the zoom lens that the present embodiment provides, but adopt position to fix and the simple liquid crystal lens of structure, by the accurate control to the voltage put on liquid crystal lens, even if do not make physical motion camera lens there is Zoom effect, therefore in contrast, the reliability when zoom lens that the present embodiment provides uses is higher.
The application of current zoom lens control device on the hand-hold electronic equipments such as mobile phone is more and more extensive, therefore more and more stricter to the requirement of zoom lens control device compact in size, and the element of VCM is more, by the restriction of prior art, the thickness of VCM, after certain limit, cannot be accomplished thinner, optical lens is on the basis ensureing good optical property, its thickness also cannot be accomplished thinner, and these factors all make the thickness of zoom lens control device cannot be thinning, are more and more difficult to the demand meeting equipment miniaturization.And, zoom lens control device of the prior art changes the focal length of camera module by VCM change lens and sensitive chip relative position, lens increases 0.2mm than during vista shot with the distance of sensitive chip approximately when close shot is taken, and this also causes the thickness of zoom lens control device to become large.Zoom lens provided by the present invention utilizes LCD lens to replace VCM and partial optical lens, liquid crystal lens is planar structure, thickness can be accomplished thinner than optical lens, and between liquid crystal lens, between liquid crystal lens and optical lens, relative position between each lens and sensitive chip is all fixing, displacement during prior art zoom lens control device medium long shot conversion close shot is there is not during zoom, therefore do not need to consider that the empty avoiding of this shift length is (in the design of miniature video camera module when design with camera module matching structure, thinning 0.2mm is a very large progress), thus make the thickness under the prerequisite ensureing the function that conventional zoom device has of the zoom lens in the present invention thinner, be more suitable in the miniaturized electronicss such as mobile phone.
Owing to avoiding the usage quantity using VCM and reduce optical lens, zoom lens provided by the present invention significantly can also reduce production cost.This is that because the VCM assembly in existing zoom lens control device is many, require that size is little, die cost is high, the opening period of optical lens is long, die cost is high, for 8,000,000 now common pixel mobile phone camera modules.Its zoom lens control device (VCM+lens) is about 2.8 U.S. dollars, wherein VCM is about 1.3 U.S. dollars, lens is probably 1.5 U.S. dollars, liquid crystal lens of the present invention is no more than 0.2 U.S. dollar through assessed cost, therefore adopt liquid crystal lens to substitute VCM and partial optical lens, the production cost of zoom lens control device can be reduced significantly.In addition, the zoom lens in the present invention can save operation lens being screwed in VCM in actual production, saves focusing operation etc., and the operation of saving all is conducive to saving production cost.And, due to the camera module that correspondence is dissimilar, required zoom lens control device is also different, corresponding VCM and the type of optical lens all need to carry out matched design, zoom lens of the present invention controls focal length variations by change in voltage, so a zoom lens can be suitable for dissimilar camera module, commonality is better, thus saves the cost of development of camera module.
In addition, compare that VCM assembly is more, assembling is complicated, component size requires small but excellent feature, the present invention adopts the liquid crystal lens that structure is simple, manufacture difficulty is less superpose with optical lens, so zoom lens is easy to assemble production, and then yields is higher.

Compared with prior art, technical scheme provided by the present invention at least has the following advantages:
Zoom lens provided by the present invention and camera module, at least 1 liquid crystal lens and at least 1 optical lens is adopted to be superimposed to form zoom lens, different deflection angles is produced under the control of the varying strength voltage that the liquid crystal molecule in liquid crystal lens applies at control electrode, thus the optical lens of different focal can be simulated, make camera lens have the function of zoom.Because zoom lens provided by the present invention is avoided using VCM, during zoom there is not physical motion in each element, therefore avoid zooming procedure VCM to move forward and backward the element produced caused by vibrations and easily decline in aging, serviceable life and the problem such as failure rate rising, improve the reliability of zoom lens and camera module.
Because VCM assembly is more, optical lens is by the restriction of the optical property that himself will reach, the two all cannot accomplish that thickness is thinner, technical scheme provided by the present invention adopts liquid crystal lens to replace VCM and partial optical lens, liquid crystal lens is planar structure, himself thickness opposing optical lens is less, and it is thinner that the zoom lens therefore in the present invention can realize thickness; And to drive optical lens to move the mode realizing zoom by VCM in prior art different, the position of the relative sensitive chip of each lens of zoom lens provided by the present invention is fixed, and is not subjected to displacement, so the Thickness Ratio of zoom lens is of the prior art thinner.
Because the usual assembly of VCM is more, compared with little, size causes that manufacture difficulty is large, die cost is high, the making die cost of optical lens is high, opening period is long, zoom lens provided by the present invention is avoided using VCM, and reduce the quantity of optical lens use, the liquid crystal lens replacement VCM adopting cost of manufacture low and the effect of partial optical lens, thus reduce the production cost of zoom lens and camera module.
