Currently, fingerprint recognition is widely used in the every aspect of people's life as the bio-identification means of main flow, most
It is exactly the application in door lock that routinely also daily-life related the most.At present semiconductor fingerprint module increasingly by
Favor, but it does not have backlight compared to optical finger print module, in use, user can not be made simply to obtain in the environment of dark
The accurate location into fingerprint is enrolled, is that the use in insufficient light environment causes inconvenience.Under the conditions of the existing darkness for solution
User quick and precisely knows that the scheme of fingerprint identification module position mainly has two classes, a kind of directly to be known by external light source for fingerprint
Other module position provides illumination, and the another kind of diffuser plate or light guide plate that special shape is set in fingerprint module outer ring, diffuser plate is just
Lower section, which is set, directly goes out luminous light source, is scattered the soft degree of increase light to the light sent by diffuser plate, or leading
One end installation light source of the tabula rasa away from fingerprint module, the light for being sent light source by light guide plate are directed to fingerprint module outer ring.
Although these schemes can play a part of indicating fingerprint identification module position, exterior lighting is to enable users to see fingerprint mould clearly
Block position is simultaneously smoothed out fingerprint typing operation and needs to reach certain illumination and could realize, to ensure that effect is likely to result in lock
Has overall power increase, although and the scheme of diffuser plate or light guide plate is further to lead to above by being set in fingerprint module outer ring
Crossing the mode of comparison of light and shade can accurately indicate that the position of fingerprint module and shape make the smooth typing fingerprint of user, but in diffuser plate
Lower section, which is set, directly goes out radiant because distance is too near, scattering process unobvious of the diffuser plate to light source, it is bright to easily cause indicator lamp
Effect between dark phase, and the effect of light guide plate light extraction position brightness irregularities is easily caused by way of light-guide plate guides light
Fruit, and the cost of manufacture of light guide plate is higher.On the other hand, semiconductor fingerprint module instruction device structure is fixed at present, it is impossible to

Shape identical aperture, user is set to know the position of fingerprint identification module exactly by distinct comparison of light and shade in dark surrounds
And the effective coverage of fingerprint typing, by setting even optical cavity at the fingerprint sensor back side, the light that light source is sent is in even optical cavity
Multiple diffusing reflection or scattering are carried out inside surface or material, reaches even light, the effect of colour mixture, is emitted eventually through light penetrating ring, is protected
The photochromic homogeneous soft of emergent ray is demonstrate,proved.While the shape of even optical cavity can do diversified design and cause this variety of shells of adaptation
The semiconductor fingerprint module instruction device of structure is not limited peripheral assembling structure, can be adapted to the shell of a variety of fingerprint modules
Structure.
