Accompanying drawing herein is merged in specification and constitutes the part of this specification, shows the implementation for meeting the application Example, and it is used to explain the principle of the application together with specification.

Specific embodiment

The application is described in further detail below by specific embodiment and with reference to accompanying drawing.

As shown in figure 1, the embodiment of the present application provides a kind of fingerprint module, the fingerprint module can be specifically electronic equipment In for sensing the module of fingerprint signal, it can include FPC (FlexiblePrinted Circuit, FPC) plate 10th, keeper 11, chip 12 and protective layer 13, FPC plates 10, chip 12 and protective layer 13 are sequentially stacked fixation, and keeper 11 is (OK Be referred to as in the industry " Holder ", " Ring rings " or " Bezel ") effect be to support, protect, decorating fingerprint module, it can pacify The side of the structure formed after stacked loaded on FPC plates 10, chip 12 and protective layer 13.More specifically, keeper 11 is fixed in Between FPC plates 10 and screen, keeper 11 can be directly fixed on FPC plates.

Loophole 100, to improve the structural strength of FPC plates 10, can thereon be opened up with integrated stiffening plate on FPC plates 10, should Loophole 100 could be arranged to one, and its shape and size can flexibly be set, and for the ease of processing, the embodiment of the present application is excellent It is cylindrical hole to select the loophole 100.Keeper 11 includes transmittance section 110, and transmittance section 110 is along the light path at loophole 100 Direction is extended at screen from loophole 100.Transmittance section 110 can be made of transparent material or trnaslucent materials, example Such as glass, jewel, ceramics or plastics material.After being arranged such, the light of the lower section of FPC plates 10 can just first pass through printing opacity Hole 100, then passed through from transmittance section 110, eventually arrive at screen, enter in the viewing area of access customer.

After using above-mentioned fingerprint mould, also just indicator lamp can be set in the lower section of FPC plates 10, the indicator lamp is used for electricity Charging, short message, phone of sub- equipment etc. are pointed out.Light propagation path shown in arrow line as shown in Figure 1, indicator lamp The light of injection can be mapped on screen by loophole 100 and transmittance section 110, and the letter that indicator lamp sends is seen in order to user Number.Through hole is opened up on screen compared to direct described in background technology, loophole 100 is opened up on FPC plates 10 less Easily limited by space, therefore also can just be opened up larger loophole so that the signal that indicator lamp sends is more readily spotted, And then improve the indicating effect of indicator lamp.In addition, loophole 100 is opened in the place for being not easy to be seen so that electronic equipment Appearance property improve therewith.

In order to shorten the light path of the light of indicator lamp injection as far as possible, the axis of loophole 100 can be made perpendicular to FPC plates 10 Extended surface.In addition, in the section of the extended surface of FPC plates 10, the bearing of trend of transmittance section 110 can be parallel to saturating The optical path direction of unthreaded hole 100.After adopting the structure, transmittance section 110 along the optical path direction perpendicular to loophole 100 size It is controllable smaller, can reliably ensure the efficient propagation of light.

In a kind of embodiment, keeper 11 may also include fixed part 111, the fixed part 111 and the vertical phase in transmittance section 110 Even, and fixed part 111 is fitted fixation with FPC plates 10.Keeper 11 and FPC plates can just be realized by fixed part 111 herein Reliability between 10 is fixed, improves the structural strength of fingerprint module, while preventing the position of transmittance section 110 from change occur and causing There is error in the light transmission of indicator lamp.

When keeper 11 includes transmittance section 110 and fixed part 111, transparent material or trnaslucent materials system can be used Transmittance section 110 is made, and fixed part 111 is manufactured using non-transparent material so that only transmittance section 110 has printing opacity in keeper 11 Property.But, in order to improve the translucency of keeper 11, preferably to propagate the light that warning light sends, transparent material can be used Material or trnaslucent materials manufacture whole keeper 11, specifically can be using materials such as glass, jewel, ceramics or plastics.

In order to propagate light better by loophole 100, loophole 100 can be set to multiple, each loophole 100 Be arranged at intervals on FPC plates 10, increase the transmission area of light with this, improve the intensity of light so that user can it is more directly perceived, The signal that quickly identification indicator lamp sends.Further, the irradiation of the light that each loophole 100 can send according to indicator lamp Scope is arranged in a ring, with this evenly, more fully propagate light.

In another embodiment, can be using following setting：On optical path direction at loophole 100, the throwing of transmittance section 110 Shadow face covers the perspective plane of loophole 100.Can that is, the clear field of transmittance section 110 and the clear field of loophole 100 can With equal, or transmittance section 110 clear field of the clear field more than loophole 100 so that the light projected in loophole 100 Line can completely extend across transmittance section 110 as far as possible, and the light intensity reached at screen is increased with this.

Based on said structure, the embodiment of the present application also provides a kind of electronic equipment, and the electronic equipment can be mobile phone, flat board Apparatus such as computer, it includes the fingerprint module described by mainboard, indicator lamp and any of the above-described embodiment, and indicator lamp is arranged at fingerprint Between module and mainboard, the light of indicator lamp can pass through the loophole 100 of fingerprint module, and eventually pass through the saturating of fingerprint module Light portion 110, is radiated on screen.Specifically, indicator lamp can use LED, and it can be integrated on mainboard, or is installed on On other parts, then electrically connected with mainboard.

The preferred embodiment of the application is the foregoing is only, the application is not limited to, for the skill of this area For art personnel, the application can have various modifications and variations.It is all within spirit herein and principle, made any repair Change, equivalent, improvement etc., should be included within the protection domain of the application.
