Terms such as " settings " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected or integral；It can be with
It is mechanical connection or electrical connection；It can be directly connected, can also be indirectly connected, can also be by intermediary
The interaction relationship of connection or two elements inside two elements.It for the ordinary skill in the art, can be with
The concrete meaning of above-mentioned term in the present invention is understood as the case may be.
As shown in Figure 1, the embodiment of the present invention provides a kind of super-thin electronic equipment camera, which can be applied to respectively
Kind electronic equipment, such as smart mobile phone, tablet computer/IPAD, personal digital assistant（PDA）And portable notebook computer etc. is set
It is standby.The super-thin electronic equipment camera includes camera module 1 and device housings 2, and wherein camera module 1 includes lens group 11
With sensitive chip 12, the protective sheet 21 that lens group 11 is provided with protection camera lens is corresponded on device housings 2.
Cutoff filter 22 is further included in the embodiment of the present invention, the cutoff filter 22 is arranged on protective sheet
In 21, it is used to implement absorption and/or reflection infrared light.
The embodiment of the present invention is while feux rouges is eliminated, since cutoff filter 22 is arranged on electronic equipment casing
In 2 protective sheet 21, the thickness of camera module 1 can be significantly reduced, is conducive to the slimming design of electronic equipment, improves and use
Family is to the usage experience of electronic equipment.Strengthen outside equipment in addition, the cutoff filter 22 of this structure setting can also play
The protective effect of protective sheet 21 on shell 2.
As shown in Fig. 2, the protective sheet 21 includes the cutoff filter substrate being cascading from left to right
211st, infrared filtering film 212, glass substrate 213 and tempering film 214.Cutoff filter substrate 211 and infrared filtering film 212
Cutoff filter 22 described above is formd, infrared filtering film 212 is set by plating so that cutoff filter substrate
211 dichroism is more regular, improves the infrared filtering performance of cutoff filter 22.Due to being provided with infrared cutoff
The thickness of filter sheet base plate 211 and infrared filtering film 212, cutoff filter substrate 211 and infrared filtering film 212 causes this
213 glass substrate 213 more of the prior art of glass substrate of inventive embodiments can do thinner, and can reach same protection
Intensity, therefore cutoff filter substrate 211 and infrared filtering film 212 will not additionally increase the general thickness of protective sheet 21.
As a further improvement, the cutoff filter 22 of the embodiment of the present invention can also directly make as protective sheet 21
With, you can glass substrate 213 described above is removed, protective sheet 21 only includes infrared section be cascading from left to right
Only filter sheet base plate 211, infrared filtering film 212 and tempering film 214 can further reduce the integral thickness of protective sheet 21.
As a further improvement, the left side of the cutoff filter substrate 211 is additionally provided with antireflection anti-reflection film 215.
