During upper surface, if cover-plate glass upper surface a part is contacted with fingerprint valley, light occurs multiple full transmitting and is pierced by cover-plate glass side
Face simultaneously passes through on lens focus to photosensitive array, forms bright fringes；If cover-plate glass upper surface a part is contacted with fingerprint ridge, by
Become coarse in contact surface, diffusing reflection occurs herein for light, it is difficult to form the light that penetrates for reaching photosensitive array, form the filaments of sun
Line.The paddy ridge information of fingerprint can be converted into the light and shade stripe information on photosensitive array by the device.
Since the light that light source is sent out has carried out multiple total reflection in cover-plate glass, can be formed on cover-plate glass surface
Multiple fingerprint detection regions, as shown in Fig. 2, multigroup " light source-lens-photosensitive array " (four groups are only shown in figure) is set, it can be with
By multiple fingerprint detection regions unicom, entire display screen is covered, sequentially or simultaneously opens light source, accordingly checks that photosensitive array connects
The finger print information received so as to obtain the finger print information on entire display screen, realizes the fingerprint to entire display screen any position
It is identified.
But with the increase of optical fingerprint identification system usage time, cut and dirt can be generated on cover-plate glass surface
Stain etc. is unfavorable for the factor of finger print information acquisition.Light projects cover-plate glass upper surface, can also be formed in cut and spot
Diffusing reflection, and then interference is generated to finger print information on photosensitive array, the discrimination power of finger print information is caused to decline.
For fingerprint identification method in the prior art discrimination power it is low the problem of, not yet propose effective solution party at present
Case.
