Aniris recognition assembly 100 for anelectronic device 300 and theelectronic device 300 according to an embodiment of the present invention are described below with reference to fig. 1 to 8. Theelectronic device 300 may be a mobile phone, a tablet computer, an electronic door, or the like.
As shown in fig. 1, theiris recognition assembly 100 for anelectronic device 300 implemented according to the present invention includes acover plate 140, amain board 110, aniris camera 120, a firstinfrared lamp 131, a secondinfrared lamp 132, and a deflection assembly.
Specifically, themain plate 110 is disposed spaced apart from thecover plate 140. For example, referring to fig. 6 and 7, themain board 110 may be disposed at a rear side of thecover plate 140, and thecover plate 140 may be disposed at a front side of thedisplay screen 200. Themain plate 110 may be substantially parallel to thecover plate 140. Optionally, thecover plate 140 is a glass cover plate. Therefore, the display effect of theelectronic device 300 can be enhanced, and the production cost can be saved.
Theiris camera 120 is connected to themain board 110 and is located on a side of themain board 110 facing thecover plate 140. The firstinfrared lamp 131 is connected to themain board 110, and the firstinfrared lamp 131 is located on one side of themain board 110 facing thecover plate 140 and spaced from theiris camera 120. The secondinfrared lamp 132 is connected to themain board 110, and the secondinfrared lamp 132 is located on a side of themain board 110 facing thecover plate 140 and spaced from theiris camera 120.
Referring to fig. 6 and 7, theiris camera 120, the firstinfrared lamp 131, and the secondinfrared lamp 132 are located on the same side surface of themain board 110 and theiris camera 120, the firstinfrared lamp 131, and the secondinfrared lamp 132 are disposed to be spaced apart from each other. The firstinfrared lamp 131, theiris camera 120, and the secondinfrared lamp 132 may be arranged substantially in a straight line in the left-right direction. The firstinfrared lamp 131 and the secondinfrared lamp 132 may be located on the same side of the iris camera 120 (as shown in fig. 1-3), and the firstinfrared lamp 131 and the secondinfrared lamp 132 may also be located on two sides of the iris camera 120 (for example, on the left and right sides of the iris camera 120). Here, it should be noted that, when the human body stands facing the side surface of themain board 110 facing the cover plate, the direction of the left hand side of the human body may be understood as the direction "left" in the present application, and correspondingly, the direction of the right hand side of the human body may be understood as the direction "right" in the present application.
The firstinfrared lamp 131 and the secondinfrared lamp 132 in the present invention may be general infrared lamps, that is, may not have a deflection function, and do not need to be customized, so the firstinfrared lamp 131 and the secondinfrared lamp 132 in the present invention have a short manufacturing cycle and low manufacturing cost.
A deflection assembly is provided on thecover plate 140, the deflection assembly including afirst deflection portion 1411 and asecond deflection portion 1412, thefirst deflection portion 1411 being opposite to the firstinfrared lamp 131, thesecond deflection portion 1412 being opposite to the secondinfrared lamp 132, thefirst deflection portion 1411 being configured to deflect the first light emitted from the firstinfrared lamp 131 toward a direction close to a central axis of theiris camera 120 to deflect the first light to theleft eye 400 of the person when the person's eye is directed at theiris camera 120, the second deflection portion being configured to deflect the second light emitted from the second infrared lamp toward a direction close to the central axis of the iris camera to deflect the second light to theright eye 500 of the person when the person's eye is directed at the iris camera.
For example, when theiris recognition module 100 is applied to an electronic device 300 (e.g., a mobile phone, a tablet pc, etc.), and theelectronic device 300 needs to be unlocked through iris recognition, the human eye may face theiris camera 120, a first light emitted by the firstinfrared lamp 131 is received by theleft eye 400 of the human after being deflected by a certain angle by thefirst deflection portion 1411, a second light emitted by the secondinfrared lamp 132 is received by theright eye 500 of the human after being deflected by a certain angle by thesecond deflection portion 1412, and theiris camera 120 realizes unlocking by capturing infrared light received by theleft eye 400 and theright eye 500 of the human.
Therefore, by providing the first deflectingportion 1411 for deflecting the first light emitted from the firstinfrared lamp 131 toward the direction close to the central axis of theiris camera 120 and the second deflectingportion 1412 for deflecting the second light emitted from the secondinfrared lamp 132 toward the direction close to the central axis of theiris camera 120 on thecover plate 140, the infrared light of the two infrared lamps are deflected to theleft eye 400 and theright eye 500 of the person, respectively, and the intensity of the infrared light received by theleft eye 400 and theright eye 500 of the person is enhanced without increasing the current of a single infrared lamp, so that the infrared light captured by theiris camera 120 from the eyes of the person can be increased, and the recognition efficiency and the unlocking success rate of theiris recognition module 100 are improved.
Meanwhile, the current of a single infrared lamp can be reduced, and compared with the technical scheme that the current of a single infrared lamp is increased in the related art, the heating problem caused by the increase of the current is avoided, the heat dissipation problem of theelectronic device 300 can be effectively improved, and the cruising ability of the electronic device can be improved. In addition, the firstinfrared lamp 131 and the secondinfrared lamp 132 in the present invention may be ordinary infrared lamps, that is, may not have a deflection function, and do not need to be customized, so the firstinfrared lamp 131 and the secondinfrared lamp 132 in the present invention have a short manufacturing cycle and a low manufacturing cost, which are beneficial to realizing the commonalization of the infrared lamps, and the problem of the deflection angle of the infrared light may not be considered when assembling, so that the distance between the firstinfrared lamp 131 and theiris camera 120 and the distance between the secondinfrared lamp 132 and theiris camera 120 may be changed according to actual needs.
Thefirst deflection portion 1411 and thesecond deflection portion 1412 in the present application may be designed to have different deflection angles according to requirements, so as to achieve any deflection angle of the infrared light (i.e. the first light and the second light), which greatly improves the stacking of the whole device, and the problem of the deflection angle of the infrared light (i.e. the firstinfrared light 131 and the second infrared light 132) may not be considered during stacking, and the distance between the firstinfrared light 131 and theiris camera 120 and the distance between the secondinfrared light 132 and theiris camera 120 may be changed arbitrarily, and when the positions of theiris camera 120, the firstinfrared light 131, and the secondinfrared light 132 on electronic devices such as a mobile phone are changed, only thefirst deflection portion 1411 or thesecond deflection portion 1412 needs to be made again, which has a short processing cycle and low cost, and affects a very little progress of the whole item. In addition, the infrared lamp does not need to be specially customized, so that the cost for customizing the infrared lamp can be reduced, and the sharing of the infrared lamp is favorably realized.
According to theiris recognition assembly 100 for the electronic device of the embodiment of the present invention, by providing the firstinfrared lamp 131 and the secondinfrared lamp 132, and providing thefirst deflection portion 1411 opposite to the first infrared lamp 141 and thesecond deflection portion 1412 opposite to the secondinfrared lamp 142 on thecover plate 140, the first light emitted from the firstinfrared lamp 131 can be deflected to theleft eye 400 of the person, the second light emitted from the secondinfrared lamp 132 can be deflected to theright eye 500 of the person, the infrared light received by the human eye is enhanced without increasing the current of a single infrared lamp, and further the infrared light captured by theiris camera 120 from the human eye can be increased, and the recognition efficiency and the unlocking success rate of theiris recognition assembly 100 are improved. In addition, since it is not necessary to separately customize the infrared lamp, the cost can be reduced and the infrared lamp can be shared.
According to some embodiments of the present invention, the firstinfrared lamp 131 and the secondinfrared lamp 132 are located on the same side of theiris camera 120. Referring to fig. 1-3, the firstinfrared lamp 131 and the secondinfrared lamp 132 may be located at the left side of theiris camera 120. One of the firstinfrared lamp 131 and the secondinfrared lamp 132 is positioned between the other of the firstinfrared lamp 131 and the secondinfrared lamp 132 and theiris camera 120. Of course, it is understood that the firstinfrared lamp 131 and the secondinfrared lamp 132 may be located on the right side of theiris camera 120. Simple structure and convenient processing.
In the present embodiment, a distance between the central axis of the above-mentioned one of the firstinfrared lamp 131 and the secondinfrared lamp 132 and the central axis of theiris camera 120 is L, and L satisfies: l is more than or equal to 15mm and less than or equal to 40 mm. Therefore, the layout of theiris recognition assembly 100 on themain board 110 can be optimized, the light supplement effect of the firstinfrared lamp 131 and the secondinfrared lamp 132 can be enhanced, the stability and accuracy of the iris recognition function can be enhanced, and the reliability of theelectronic device 300 can be improved. Preferably, L ═ 20 mm.
Specifically, in other embodiments of the present invention, the firstinfrared lamp 131 and the secondinfrared lamp 132 are respectively located on the left and right sides of theiris camera 120. For example, referring to fig. 4 and 5, the firstinfrared lamp 131 may be located on the left side of theiris camera 120, and the secondinfrared lamp 132 may be located on the right side of theiris camera 120.
Specifically, the distance between the central axis of the firstinfrared lamp 131 and the central axis of theiris camera 120 is L1, the distance between the central axis of the secondinfrared lamp 132 and the central axis of theiris camera 120 is L2, and L1 is L2. Alternatively, the firstinfrared lamp 131 and the secondinfrared lamp 132 may be symmetrically disposed at left and right sides of theiris camera 120. Thereby, the infrared light received by the left andright eyes infrared lamps main board 110, optimizing the layout of themain board 110.
Optionally, the distance L1 between the central axis of the firstinfrared lamp 131 and the central axis of theiris camera 120 satisfies: l1 is more than or equal to 15mm and less than or equal to 40 mm. Through repeated tests, when the distance between the central axis of the firstinfrared lamp 131 and the central axis of theiris camera 120 is 15-40mm (i.e., L1 is greater than or equal to 15mm and less than or equal to 40mm), the layout of theiris recognition assembly 100 on themain board 110 can be optimized, the light supplement effect of the firstinfrared lamp 131 can be enhanced, the stability and accuracy of the iris recognition function can be enhanced, and the reliability of theelectronic device 300 can be improved. Preferably, L1 is 20 mm.
It is understood that the distance L2 between the central axis of the secondinfrared lamp 132 and the central axis of theiris camera 120 may also satisfy: l2 is more than or equal to 15mm and less than or equal to 40 mm. Preferably, L1 is 20 mm. Thereby, the stability and accuracy of the iris recognition function can be further enhanced.
In some embodiments of the present invention, thefirst deflection part 1411 may deflect the first light emitted from the firstinfrared lamp 131 by 3 ° to 15 °, and thesecond deflection part 1412 may deflect the second light emitted from the secondinfrared lamp 132 by 3 ° to 15 °. Thereby, the structure of theiris recognition assembly 100 can be made more compact.
According to some embodiments of the present invention, thefirst deflecting portion 1411 is a first polarizing member provided on thecover plate 140, and thesecond deflecting portion 1412 is a second polarizing member provided on thecover plate 140. Specifically, referring to fig. 2, the thicknesses of the first and second polarization members (the "thickness" refers to the size of the first and second polarization members in the direction from theiris camera 120 to the cover plate 140) gradually decrease in the direction approaching theiris camera 120. Therefore, when the light emitted by the firstinfrared lamp 131 and the secondinfrared lamp 132 is deflected by the corresponding polarizing members (i.e., the first polarizing member and the second polarizing member), the light is deflected toward the direction in which the thickness of the polarizing members is large, so that more infrared lights can be emitted toward theleft eye 400 and theright eye 500 of the user, when the user faces theiris camera 120, more light is emitted toward the user, and then theiris camera 120 can capture more infrared lights to realize unlocking.
Optionally, the first polarizer and the second polarizer are attached to thecover plate 140 by an adhesive layer. Therefore, the first polarizing piece and the second polarizing piece can be conveniently installed and fixed. For example, the first polarizer and the second polarizer may be fixed on thecover plate 140 by double-sided tape, dispensing, and the like.
According to some embodiments of the present invention, the cross-sections of the first and second polarizers (the "cross-section" refers to a plane that a plane parallel to the central axis of theiris camera 120 cuts through the polarizers) are formed in a triangle or a trapezoid. Simple structure and convenient processing.
Alternatively, the first and second polarizers may be PMMA (polymethyl methacrylate) pieces, PC (Polycarbonate) pieces, or the like. Therefore, the cost can be reduced, the processing period is further shortened, and the processing and forming period generally only needs about one week, so that the progress of the whole project is slightly influenced.
According to some embodiments of the present invention, the first and second polarizers are spaced apart on thecover plate 140. Therefore, the material consumption of the deflection assembly can be reduced, and the material is saved.
In other embodiments of the present invention, the first polarizer and the second polarizer are integrally formed. Therefore, the processing technology of the deflection assembly can be simplified, and the processing cost can be reduced.
According to further embodiments of the present invention, referring to fig. 3 and 4, one of a first region of thecover plate 140 opposite to the firstinfrared lamp 131 and a second region opposite to the secondinfrared lamp 132 is provided with adeflection groove 142 to form afirst deflection portion 1411 or asecond deflection portion 1412 at one of the first region and the second region. Specifically, the deflection slit 142 may be provided on a first region of thecover plate 140 opposite to the firstinfrared lamp 131 to form thefirst deflection portion 1411 at the first region, and the deflection slit 142 may be provided on a second region of thecover plate 140 opposite to the secondinfrared lamp 132 and to form thesecond deflection portion 1412 at the second region. It is understood that the deflection portion on the other of the first and second regions of thecover plate 140 is a polarizing member.
Therefore, the light emitted by the firstinfrared lamp 131 or the secondinfrared lamp 132 can also be deflected towards the direction close to theiris camera 120, so that more light can be emitted into theleft eye 400 and theright eye 500 of the person, the recognition efficiency of theiris recognition assembly 100 is improved, and the unlocking success rate of theelectronic device 300 is improved. In addition, when thedeflection grooves 142 are respectively formed in the first region and the second region, the occupied space of the deflection member can be saved, so that the structure of theiris recognition assembly 100 can be more compact.
Optionally, thedeflector groove 142 has an open mouth that opens toward themain plate 110. For example, thedeflection groove 142 may be formed by outwardly recessing the second surface of thecap plate 140. Simple structure, processing is convenient, is favorable to reducing the processing cost.
Specifically, according to some embodiments of the present invention, in a direction close to theiris camera 120, the bottom wall of the deflection slit 142 extends toward a direction close to the infrared lamp (i.e., the firstinfrared lamp 131 or the second infrared lamp 132) corresponding thereto. The bottom wall of thedeflection groove 142 refers to a wall surface of the deflection groove opposite to the corresponding infrared lamp. For example, the deflection angle ofdeflection slot 142 may be adjusted by changing the angle of inclination of the bottom wall ofdeflection slot 142. Thus, the light emitted from the firstinfrared lamp 131 and the secondinfrared lamp 132 can be deflected as desired, and the deflection slit 142 has a simple structure and is easy to manufacture.
According to some embodiments of the present invention, the bottom wall of thedeflection slot 142 is formed in a planar configuration. Simple structure and easy processing. Alternatively, the shape of the cross section of the deflection groove 142 (the "cross section of thedeflection groove 142" means a plane obtained by cutting thedeflection groove 142 with a plane parallel to the central axis of the iris camera 120) may be triangular, trapezoidal, or the like.
According to other embodiments of the present invention, the bottom wall of the deflectinggroove 142 is formed in a curved structure, and a tangent of each point on the bottom wall of the deflectinggroove 142 is inclined toward a direction close to the infrared lamp corresponding thereto in a direction radially outward from the central axis of theiris camera 120. This also ensures that the infrared light is deflected in the direction of thehuman eye 400.
Specifically, in the direction from the firstinfrared lamp 131 to theiris camera 120, the size of the firstinfrared lamp 131 is smaller than the size of thefirst deflecting part 1411. Therefore, it can be ensured that the first light emitted by the firstinfrared lamp 131 can be deflected by thefirst deflecting portion 1411, so that more light can enter theleft eye 400 of the person, and the unlocking success rate of theelectronic device 300 can be improved.
Further, in the direction from the secondinfrared lamp 132 to theiris camera 120, the size of the secondinfrared lamp 132 is smaller than that of thesecond deflection part 1412. Therefore, the second light emitted by the secondinfrared lamp 132 can be deflected by thesecond deflection portion 1412, so that more light can enter theright eye 500 of the person, and the unlocking success rate of theelectronic device 300 is further improved.
According to some embodiments of the present invention, at least one of the firstinfrared lamp 131 and the secondinfrared lamp 132 emits infrared light in a wavelength range of 900nm to 940nm (i.e., 900 nm. ltoreq. lambda. ltoreq.940 nm). Specifically, the wavelength range of the infrared light emitted by the firstinfrared lamp 131 is 900nm to 940nm, or the wavelength range of the infrared light emitted by the secondinfrared lamp 131 is 900nm to 940nm, or both the wavelength of the infrared light emitted by the firstinfrared lamp 131 and the wavelength of the infrared light emitted by the secondinfrared lamp 132 are 900nm to 940 nm.
The infrared light of 900 nm-940 nm is not visible tohuman eyes 400 while providing an effective light source for iris imaging, so that user experience is better, and the recognition effect of the infrared light of 900 nm-940 nm on black irises is better. Therefore, theiris identification assembly 100 can be used for specific Asian people, meanwhile, the fact that infrared light is invisible when the temperature drifts can be achieved, and using comfort and identification efficiency are improved.
