Description
Technical field
The utility model is related to identifying system technical fields, and in particular to a kind of optical finger print identification system based on OLED screen
System.
Background technology
Line identification technology is to acquire somatic fingerprint image by fingerprint sensor, the fingerprint image then stored with system
It compares, to discriminate one's identification, due to the uniqueness of fingerprint and the portability of fingerprint identification technology, has been applied to industry control at present, pacify
It protects, the multiple fields such as consumer electronics, there is capacitance type fingerprint identification, optical finger print identification, a variety of realizations such as ultrasonic fingerprint identification
Mode.Optical fingerprint identification technology is preferable with respect to imaging effect, by acquiring the light reflected from somatic fingerprint, carries out letter
Number processing and conversion, formed fingerprint image, compared with system, to judge that identity, OLED screen are a kind of emerging display screen sides
Case, can be used for consumer electronics, and the multiple fields such as industry control have the advantages that contrast is high, and thickness is thin, power saving.Existing optics refers to
Line identification technology structurally and functionally still has deficiency, needs to improve, such as：Easily influenced by ambient light, under strong illumination, identification spirit
Sensitivity declines；There must be light source to send out visible light out of sensor to the external world, in some application scenarios, such as mobile phone consumer product
Middle application, this luminescence phenomenon when use, reduces the usage experience of user, while the identification of product is inadequate.
Invention content
Problem to be solved in the utility model is：A kind of optical fingerprint identification system based on OLED screen is provided, it can
It realizes the lower fingerprint recognition of screen, OLED screen is combined with fingerprint recognition system.
The technical solution that the utility model is provided in order to solve the above problem is：A kind of optical finger print knowledge based on OLED screen
Other system, includes cover board, optical cement, fingerprint module optical cement, OLED screen, optical finger print chip and wiring board with logo,
The OLED screen is adhesive in the lower face of the cover board with logo by the fingerprint module optics, described to carry logo's
One end of cover board is equipped with half open-work that can only penetrate infrared ray, and the optical finger print chip passes through the fingerprint module optics gluing
In the lower face of the OLED screen, the position of the optical finger print chip is corresponding with the position of half open-work, the circuit
Plate is connect by gold thread with the lower face of the optical finger print chip.
Preferably, it is stored with comparison finger print information in the optical finger print chip.Optical finger print chip is by acquiring from hand
The light being reflected back on finger obtains fingerprint image, is then compared with the finger print information stored in chip, to reach depositing for fingerprint
Storage and identification function.
Preferably, the cover board with logo is made of PMMA materials.PMMA is preferable macromolecule transparent material,
Light transmittance is high, can increase the light transmittance of infrared ray.
Compared with prior art, the utility model has the advantages that：This fingerprint recognition system is easy to minimize, can be in mobile phone etc.
The lower fingerprint recognition of screen is realized in consumer-electronics applications, infrared fingerprint identification is influenced smaller by extraneous visible light.It can in the sunlight just
It is often used, and product identification can be improved with Logo on cover board.
