Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Fig. 1 is a schematic structural diagram illustrating a display assembly 100 according to an exemplary embodiment, including:

an emitting unit 110 for emitting incident light;

a conducting layer 120, located on a light path of the emitting unit 110, for converting the incident light into light within a preset angle;

a receiving unit 130, located adjacent to the transmitting unit 110, for receiving a reflected light obtained by reflecting the incident light;

the display module 140 covers the light emitting direction of the conductive layer 120.

In the embodiment of the present disclosure, the emitting unit is configured to emit light in a direction of pressing the fingerprint, and the light may be light with a predetermined wavelength, for example, light in a corresponding wavelength band such as infrared light, ultraviolet light, and green light in visible light. When the light is emitted to the finger, the light can be reflected by the finger to return to the receiving unit at the position adjacent to the emitting unit. The receiving unit only needs to receive the light of the wave band corresponding to the transmitting unit. Because the fingerprint of the finger has uneven lines, different positions of the finger can reflect light in different directions or intensities when the light is irradiated.

The finger fingerprint can be restored by processing the reflected light received by the receiving unit, so that the fingerprint identification is realized.

Because the light that the emission unit transmitted can present the angle of dispersing, consequently, if the fingerprint collection subassembly that contains above-mentioned emission unit, conducting layer and receiving element sets up in electronic equipment's inside, and there is comparatively complicated structure around it, then can produce diffuse reflection to the light that disperses, and the reflection that does not pass through the finger will be received by the receiving element, or just gets into the receiving element through other reflections after the finger reflection again. Therefore, the receiving unit cannot sense accurate finger lines and is difficult to identify fingerprints.

Therefore, in the embodiment of the present disclosure, the angle of the light emitted by the emitting unit is adjusted by using the transmitting layer located on the optical path of the emitting unit, so that the light emitted by the emitting unit is directed to the direction of the finger as much as possible. Therefore, the occurrence of diffuse reflection can be reduced, so that the reflected light received by the receiving unit can be reflected by the finger as far as possible, and the detection accuracy and sensitivity can be improved.

In some embodiments, the conductive layer covers a beam range of the incident light.

Because the structure of the emission unit is fixed, the emission unit has a fixed light-emitting angle, and therefore, the transmission layer can cover the whole light beam range. Different distances between the transmission layer and the emission unit correspond to different light beam ranges, and the larger the distance is, the larger the light beam range is. Therefore, the area of the conductive layer may be determined according to the light emitting angle of the emission unit and the distance between the conductive layer and the emission unit, thereby covering the entire light beam range. In practical application, the area of the layer can be determined by comprehensively considering the transmitting unit, the receiving unit and the proper placement position of the layer. Meanwhile, in order to enable the receiving unit to accurately receive the reflected light of the finger, the receiving unit cannot be shielded as far as possible when the light is transmitted to the layer.

Therefore, the light emitted by the emitting unit can be adjusted, and only the light within the preset angle range is transmitted to the surface of the finger, so that the diffuse reflection of the light transmitted to the surface of electronic equipment or other parts is reduced.

In some embodiments, as shown in fig. 2, the conductive layer 120 includes: a light guide hole 121 having an extending direction perpendicular to a light emitting surface of the emission unit; wherein, the inclination angle of the inner wall of the light guide hole 121 is smaller than a preset angle threshold; the incident light is transmitted through the light guide hole 121.

The light guide holes 121 may be densely distributed on the conductive layer 120, and the light guide holes 121 may be hollow holes; the light guide holes 121 may be formed of a light transmissive material or holes capable of selectively transmitting light of a specified wavelength. The light can be transmitted through the light guide hole 121 to adjust the transmission angle. Thus, the diverging light can be limited within a predetermined angle after passing through the light guide hole 121.

In some embodiments, the conductive layer 120 is specifically configured to convert the light emitted from the emitting unit into parallel light perpendicular to the direction of the conductive layer 120.

In the embodiment of the disclosure, the above-mentioned conducting layer realizes the collimation function of light, and the design of the light guide structure of the conducting layer enables the propagation direction of the light to be converted into parallel light perpendicular to the laying direction of the conducting layer, and the parallel light perpendicularly emits out of the surface of the fingerprint detection assembly and irradiates on the surface of a finger.

In some embodiments, as shown in fig. 3, the receiving unit 130 includes:

a lens 131;

an infrared filter layer 132 between the lens 131 and the photosensor 133;

and the optical sensor 133 is positioned on one side of the infrared filter layer 132 away from the lens 131 and is used for generating an electrical signal according to the received reflected light.

In the embodiment of the present disclosure, the receiving unit realizes the collection of the optical signal through the above three parts. Because infrared light cannot be perceived by human eyes and is harmless to human bodies, the light emitted by the emitting unit is infrared light. The lens converges the optical signal reflected by the finger within the detection range of the optical signal sensor. Meanwhile, the light is filtered by the infrared filter layer, and the infrared part of the light is transmitted to the optical signal sensor.

Therefore, the infrared light emitted to the finger by the emitting unit can be transmitted to the optical signal sensor, and then the optical signal sensor performs photoelectric conversion to obtain an electric signal corresponding to the fingerprint. And further, the fingerprint image can be restored through analyzing and processing the electric signal, so that the fingerprint identification is realized.

The optical signal sensor may be formed using an element having photoelectric conversion performance such as a photodiode.

In some embodiments, the light emitting surface of the transmitting unit, the receiving surface of the receiving unit and the conductive layer are all parallel to the display surface of the display module.

In the embodiment of the disclosure, the display module emits visible light in the direction of the surface of the display screen, and the emission unit emits infrared light in the direction of the surface of the display screen. The display module can be transparent to infrared light, so that the infrared light emitted by the emitting unit can reach fingers touching the surface of the display screen through the display assembly, then passes through the display module through reflection, and returns to the receiving unit.

In addition, the lower layer of the display module can be made of a selective transmission material, and only transmits infrared light but not visible light. Therefore, the visible light emitted by the display module cannot be reflected back to the detection unit after being reflected by the finger, and meanwhile, the ambient light cannot reach the receiving unit through the display module.

In the embodiment of the present disclosure, the display module may be any type of display screen used by an electronic device, and the fingerprint acquisition module including the transmitting unit, the conducting layer, and the receiving unit may be an under-screen fingerprint acquisition module disposed under the display screen. The display screen may be a display screen applied to various electronic devices, including: cell-phone, computer, panel computer, intelligent wearing equipment and any other electronic equipment that need show the function.

The display screen can be a liquid crystal display screen or an LED (light emitting diode) display screen. The display module of the liquid crystal display screen comprises a liquid crystal module, a backlight module and the like, and the display module of the LED display screen comprises display pixels formed by an LED array, a peripheral circuit and the like. Simultaneously, the upper strata of display module assembly can also cover glass for protect display module assembly.

No matter what kind of display module assembly, it all can see through the light of the corresponding wave band that the emission unit of fingerprint collection subassembly sent, for example infrared light.

Like this, when the finger touch when the surface of display screen, the light that the emission unit of the inside fingerprint collection subassembly of display screen sent just can see through display module assembly and shine finger surface, then see through display module assembly through the finger reflection again and get back to receiving element to realize the detection discernment of fingerprint.

In some embodiments, as shown in fig. 4, the display assembly 200 is a liquid crystal display; the display assembly 200 further includes:

a backlight module 220 located between the display module 210 and a fingerprint acquisition assembly 230 comprising the transmitting unit, the conductive layer and the receiving unit; the light wave band emitted from the backlight module 220 is different from the light wave band emitted from the fingerprint acquisition assembly 230.

Because liquid crystal display's display module assembly can't give out light, and need backlight unit as the light source, consequently, if the display screen is liquid crystal display, then still need set up backlight unit in display module assembly below. The light that backlight unit sent is visible white light, and through the light modulation of display module assembly, can send the light of different colours different intensity in different pixel positions to reach display effect.

In the embodiment of the present disclosure, the backlight module is different from the light-emitting light wave band of the fingerprint acquisition assembly including the emitting unit, the conducting layer and the receiving unit, so that the light emitted by the backlight module does not interfere with the fingerprint acquisition. For example, the light emitted by the emitting unit is infrared light.

Meanwhile, the backlight module is light-permeable, and here, a selective transmission material which is transparent to infrared light can be used as the lowest layer of the backlight module. Therefore, the infrared light emitted by the emitting unit and the infrared light reflected by the finger can both pass through the light-transmitting backlight module, and the visible light and the ambient light required for displaying can not reach the receiving unit for fingerprint collection through the bottom layer of the backlight module, so that the interference is reduced.

In some embodiments, the backlight module comprises:

the backlight shell, the surface of the backlight shell has the light absorbing layer.

In the embodiment of the disclosure, the backlight housing for fixing the backlight module and the display module around the backlight module, and the surfaces of various structures such as frames and shells in the display screen may have light absorbing layers made of light absorbing materials. For example, dark paint, etc. Like this, even the light that the fingerprint collection subassembly sent reflects frame equipotential on every side, also can be absorbed to reduce to reflect back to the light of receiving element, promote fingerprint detection's accuracy.

In some embodiments, the transmission unit of the fingerprint acquisition assembly is configured to emit infrared light; as shown in fig. 5, the backlight module 220 includes:

a light source 221 for emitting visible light;

a light guide layer 222, the light source being located at one side of the light guide layer edge;

and an infrared light transmission layer 223 located between the light guide layer and the conductive layer, for filtering visible light and transmitting the infrared light.

In the embodiment of the present disclosure, the backlight module of the liquid crystal display includes a light source, a light guide layer and an infrared transparent layer. The light source is located on one side of the light guide layer and can be composed of a plurality of LED light emitting units. The light emitted by the light source faces the light guide layer, and the light emitted by the light source is adjusted to be vertical and evenly emitted out of the light rays on the surface of the light guide layer by the light guide layer, so that an even light source is provided for pixels in each area of the liquid crystal display module.

The infrared euphotic layer is positioned on the lower layer of the light guide layer, and filters visible light towards the fingerprint detection assembly, so that interference of the visible light to the fingerprint detection assembly is reduced. Here, the visible light part can be reflected to the direction of the display screen surface through the mode of reflection to reduce the luminance loss of display screen, reach the effect of filtering the visible light towards fingerprint detection subassembly. Simultaneously, infrared euphotic layer still need have and sees through the infrared light function, and like this, the infrared light of fingerprint detection subassembly transmission and the infrared light of receipt all can see through backlight unit, transmit between fingerprint detection subassembly and finger to realize fingerprint detection.

In some embodiments, the backlight module further comprises:

and the diffusion layer is positioned between the light guide layer and the display module and used for diffusing the visible light.

In backlight unit, can also have the diffuse layer, the diffuse layer can also include diffusion barrier and membrane that adds lustre to, and diffusion barrier and membrane that adds lustre to all are used for adjusting out the light angle for backlight unit's visible light can evenly shine each pixel of display screen.

Meanwhile, the diffusion layer can also adopt the design of a multilayer optical film to improve the transmittance of infrared light, reduce the diffusion of the infrared light and maintain the emergent angle of the infrared light to be smaller than a preset range as far as possible, so that the accuracy of fingerprint detection is improved and a better display effect is kept.

In the embodiment of the disclosure, the electronic device may be any electronic device having a display function, the inside of the housing of the electronic device is black, and the black has a good light absorption characteristic, so that the diffuse reflection of the light emitted by the fingerprint acquisition assembly and the received reflected light inside the electronic device can be reduced, and the interference on fingerprint acquisition is reduced.

The disclosed embodiments also provide the following examples:

the fingerprint recognition on the mobile phone adopts the off-screen fingerprint recognition technology, and in one embodiment, as shown in fig. 7, the fingerprint recognition component 700 includes: a fingerprint light source 710, a reflection unit 720, and a fingerprint sensor 730.

The fingerprint light source 710 emits infrared light to obliquely irradiate the finger touching the display module 11, and the information of the fingerprint is carried through the refraction of the finger and the surface of the finger. And then irradiated to the inside of the liquid crystal display panel 10 up to the surface of the emission unit 720. And then reaches the fingerprint sensor 730 by reflection of the reflection unit 720. The fingerprint sensor 730 converts the received optical signal into an electrical signal, and transmits the electrical signal to the processor for analyzing, processing and restoring the fingerprint image.

In this way, the fingerprint light source is arranged in the non-display area of the display screen, and the usable area of the display screen is occupied; meanwhile, the placement position and the angle of the fingerprint light source need to have higher accuracy, and if deviation occurs, the effect of fingerprint detection can be seriously influenced, so that the packaging difficulty is high.

In another embodiment, the fingerprint light source is disposed under the backlight module and close to the fingerprint sensor. Adopt this kind of mode, the light that the fingerprint light source sent produces the reflection in various part positions of backlight unit below, perhaps transversely gets into fingerprint sensor through the membrane material to cause serious noise, reduce fingerprint identification's accuracy.

The fingerprint identification assembly 800 is disposed under the backlight module 12 of the display screen. The fingerprint identification assembly 800 includes a transmitting unit 810, a collimating layer 820, and a receiving unit 830.

The emitting unit 810 is an infrared LED light source, and the collimating layer 820 is located above the emitting unit 810 and is used for guiding infrared light with a divergent angle into parallel light perpendicularly facing the backlight module. Therefore, the light can be prevented from directly entering the receiving unit or entering the receiving unit through diffuse reflection under the backlight module, so that the detection effect is influenced.

The receiving unit includes a lens 831, an infrared filter 832, and an infrared sensor 833, and the infrared sensor 833 is fixed to a housing of the electronic device, a middle frame of the mobile phone, or a housing of the display module, etc. through a glue 834. Meanwhile, the lens 831 and the infrared filter 832 are fixed below the infrared sensor 833 by a fixed bracket 835. Therefore, the infrared sensor can receive the infrared light reflected by the finger from the display screen, and the fingerprint detection is realized.

In addition, it may be inside an electronic device, including: the backlight iron shell, the interior of the electronic device shell and the middle frame around the fingerprint identification component can be additionally provided with a layer of light absorbing material, such as black paint, so that the reflection and scattering of light rays are reduced.

and S106, unlocking the display screen and displaying the desktop of the mobile phone.

By the method of the embodiment of the disclosure, on one hand, the fingerprint acquisition assembly is completely arranged below the display screen, so that the space of the display screen is not occupied, and the use of the whole screen is facilitated; on the other hand, through the angle of light-emitting of adjustment detection infrared light, increase the extinction material in electronic equipment inside simultaneously, can promote fingerprint detection's the degree of accuracy, reduce the interference of noise.
