Description
Technical field
This disclosure relates to fingerprint technique field more particularly to fingerprint identification method and device.
Background technology
When total reflection refers to the interface that light is mapped to optically thinner medium by optically denser medium, it is all reflected back toward showing in former medium
As.Wherein, two media is compared, and the smaller medium of the speed of light in the medium is called optically denser medium, in the medium light
The larger medium of speed be called optically thinner medium.Total reflection phenomenon occurs and must satisfy two conditions, first, incidence angle is more than
Critical angle, second is that light injects optically thinner medium from optically denser medium.
Diffusing reflection refers to the phenomenon that light of projection on a rough surface is reflected to all directions.When a branch of parallel incident light
When line is mapped to coarse surface, surface can be light towards reflecting from all directions.Although incident ray is parallel to each other, by
It is inconsistent in the normal direction of each point, cause reflection light irregularly to be reflected to different directions.
Full transmitting and irreflexive principle is utilized in optical finger print.In the case where no finger presses, light is from light source
It projects, fingerprint sensor surface is totally reflected, and total reflection light injects convex lens, convex lens to CMOS
(Complementary Metal Oxide Semiconductor, complementary metal oxide semiconductor), at this time collected figure
It seem blank out.When there is finger to press fingerprint sensor surface, fingerprint high spot can be contacted with fingerprint sensor surface, by
This generates diffusing reflection phenomenon.The light intensity that convex lens is injected in diffusing reflection can be more much lower than being totally reflected, to ultimately form one
Height compares in white and black fingerprint image.Fig. 1 is the schematic diagram of fingerprint image.
It can be spontaneous by means of OLED (Organic Light-Emitting Diode, Organic Light Emitting Diode) screen
Light, fingerprint sensor can be placed in below screen.Screen surface is irradiated using the light source of OLED, recycle total reflection and is overflow anti-
The principle penetrated can carry out fingerprint recognition.
In the related technology, it when screen, which is in, puts out screen state, if desired carries out shielding lower fingerprint recognition, then needs to wait for screen
Light and then acquire fingerprint image.In order to ensure that screen has been completed from the switching for putting out screen state to bright screen state, wait for
Time be all set to be enough to big, this causes fingerprint recognition speed slower.
