Detailed description of the invention
Fig. 1 is the method flow diagram provided in an embodiment of the present invention based on the identification of Micro LED liquid crystal display iris capturing.
Specific embodiment
As shown in Figure 1, provided by the invention know method for distinguishing based on Micro LED liquid crystal display iris capturing, it is described in detail such as
Under:
Step S1 successively overlaps Micro LED screen, driving IC and circuit and iris capturing/identification platelet；It is adopted in iris
Collection/identification platelet is equipped with infrared lamp and camera, component thereon is overlapped in case following processes are to use.
Step S2, controller output order start iris algorithm；Controller in systems can issue instruction as needed
Deactivation iris algorithm, usually iris algorithm be in a dormant state, as long as using when just will start and worked accordingly.
Whether controller successfully judges the iris algorithm of starting, such as starts successfully, thens follow the steps S3, if unsuccessful, return
Return step S2.
Step S3 calls driving IC control driving circuit control Micro LED screen specified pixel point device to close its power supply；
Driving IC is transferred by instruction, is worked using the control sequence circuit in driving IC, control circuit control Micro LED refers to
Its power supply is closed in the power supply for determining pixel device；Judge to control whether the control power supply of specified pixel point succeeds, such as success is then held
Row step S4, such as unsuccessful, then return step S2.
The non-luminous pixel of step S4, Micro LED screen will become transparent composition transparent substrates；After the completion of control,
Due to the material property of Micro LED screen, the non-luminous pixel of screen will become transparent.Whether the specified pixel of judgement is complete
Portion becomes transparent, if so, S5 is thened follow the steps, if not, return step S3.
Infrared lamp emits infrared light and projects people through Micro LED screen transparent substrates under step S5, Micro LED screen
Face；Infrared lamp under screen is lighted, infrared light is issued, transparent substrates illumination bands is projected by Micro LED screen and need to acquire
On the face of iris.
Camera acquires eye image by Micro LED transparent substrates in real time under step S6, Micro LED screen.Starting
Camera acquires the image of human eye by Micro LED transparent substrates in real time, obtains people's eye iris according to the image of acquisition
Information data.
Collected iris is obtained identify whether data are consistent with the data comparison in storing data library by step S7, if
Unanimously, then ability acquisition identification, such as otherwise return step S1 are completed.
(by step S1-S7 process not at comprehensively)
When needing to acquire or identifying iris, infrared lamp projects infrared light to face, and camera acquires eye image simultaneously in real time
The real-time display on LCD/OLED liquid crystal display.
Human eye need to adjust the angle by the eye image of real-time display on LCD/OLED liquid crystal display and interface prompt and away from
From, while in order to cooperate camera to obtain optimized image, it is also necessary to eyes realization keeps a close watch on camera also often so as to camera
Obtain image.
The operating process that iris is acquired/identified by this traditional approach is more complex and experience is very poor, simultaneously as camera
The eye image that acquisition and liquid crystal display are shown is not in same human eye sight range, so acquisition/identification precision of images and effect
Rate is all very low.
Wherein Micro LED characteristic is that device is not transparent under power supply state.
When iris capturing/identification platelet needs work, by control driving IC and circuit, refer to Micro LED screen
Determine region not shine, exposes transparent substrates.
When iris capturing/identification platelet needs work:
A. start iris algorithm；
B. driving IC module is called；
C. pass through drive control circuit
D. the power supply of circuit control Micro LED specified pixel point device, closes its power supply；
E. after the completion of controlling, due to the material property of Micro LED screen, the non-luminous pixel of screen will become transparent.
Multiple transparent pixel collections that control is completed can serve as transparent substrates, at this time infrared lamp under Micro LED screen
Transmitting infrared light simultaneously projects face through Micro LED screen transparent substrates, and camera passes through Micro under Micro LED screen
LED transparent substrates acquire eye image in real time；When picture, while iris algorithm being called to carry out iris capturing or comparison, acquisition/knowledge
Other result is fed back to be shown in time on Micro LED liquid crystal display again.
After the completion of acquisition or identification, by control driving IC and circuit, non-luminous region normal power supply before being allowed to
Restore Micro LED screen normal luminous to show.
The eye image that camera obtains under Micro LED screen is real in Micro LED liquid crystal screen display
The acquisition precision and operating experience of iris recognition are greatly improved, ensure that the eyes of user shown in Micro LED screen
Image is consistent with the iris image angle and distance that camera obtains, and adjusting the angle distance etc. can directly be shown by liquid crystal display
It is operated with prompt, usage experience and collecting efficiency greatly improve.
Another object of the present invention is to provide the system identified based on Micro LED liquid crystal display iris capturing, the systems
System includes
Module is overlapped, for successively overlapping Micro LED screen, driving IC and circuit and iris capturing/identification platelet；
Instruction issues module, starts iris algorithm for controller output order；
