Detailed Embodiments

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0029] It should be noted that when an element is referred to as being "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0030] It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0031] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality" means two or more, unless otherwise specifically defined.

[0032] It should be known that in the field of biometric technology, fingerprint recognition, as an efficient and convenient way of identity verification, has been widely applied in various electronic devices, such as smartphones, tablets, access control systems, etc. As the core component to achieve the fingerprint recognition function, the performance and structural design of the fingerprint module are directly related to the accuracy of recognition and the user experience.

[0033] In the related art, the fingerprint module has a fingerprint acquisition area and a light-emitting area, and the light-emitting area is mostly arranged outside the fingerprint acquisition area, resulting in the fingerprint acquisition area being unable to emit light under normal working conditions, which to a certain extent affects the intuitiveness of fingerprint recognition and the user experience. Conventional fingerprint modules generally use silicone-based epoxy molding compounds as the encapsulation material for fingerprint acquisition chips. This material is in an opaque black solid state and has good mechanical strength and electrical insulation properties, but at the same time it also limits its application in optical characteristics. Since the chip itself does not have the ability to emit light and transmit light, the pattern position area on the fingerprint acquisition surface does not emit light under normal working conditions, which to a certain extent affects the intuitiveness of fingerprint recognition and the user experience.

[0034] Therefore, the present application makes improvements to the related fingerprint acquisition device and electronic device based on this.

[0035] Please refer to Figure 1 and Figure 2 , Figure 1 which shows a schematic structural diagram of the fingerprint acquisition device provided in this embodiment, Figure 2 shows the Figure 1Schematic cross-sectional structure diagram in the direction of A-A. The fingerprint acquisition device of this embodiment includes a housing 100 and an acquisition structure 200; the housing 100 is provided with an opening; the acquisition structure 200 is arranged inside the housing 100, and at least part of the acquisition structure 200 is exposed from the opening; the acquisition structure 200 includes an acquisition layer 210 and a light-emitting layer 220, the acquisition layer 210 is exposed from the opening, and the light-emitting layer 220 is arranged on the side of the acquisition layer 210 close to the inside of the housing 100; the acquisition layer 210 is used for acquiring fingerprints, and at least part of the acquisition layer 210 is a light-transmitting structure 212, so that the light of the light-emitting layer 220 is emitted from the acquisition layer 210.

[0036] It should be noted that the fingerprint acquisition device of this embodiment is mainly composed of two parts: a housing 100 and an acquisition structure 200. The housing 100 serves as the external framework of the device, which not only provides necessary protection and support, but also provides a channel for the exposure of the acquisition structure 200 through the opening thereon. The acquisition structure 200 is the core of the device and is responsible for actually completing the fingerprint acquisition work. The opening is used to define the fingerprint acquisition area, and its size needs to be adapted to the user's finger. The acquisition layer 210 is the part that directly contacts the user's finger and is usually made of a highly sensitive sensor material. The main function of the acquisition layer 210 is to capture the detailed features of the fingerprint and convert them into electrical signals for subsequent processing. The light-emitting layer 220 is arranged on the side of the acquisition layer 210 close to the inside of the housing 100, and its main role is to provide a uniform and sufficient-intensity light source. The light-emitting layer 220 usually includes LED lamp beads or other types of light-emitting elements, and these elements are precisely arranged to ensure that the light can evenly cover the entire acquisition area. The light of the light-emitting layer 220 is emitted through the light-transmitting part of the acquisition layer 210.

[0037] The current fingerprint acquisition device has an opaque structure in the fingerprint acquisition area, which makes it difficult for users to directly observe the fingerprint acquisition result. However, in this application, the acquisition layer 210 exposed at the opening is set as the light-transmitting structure 212, and users can directly observe the light-emitting state of the fingerprint acquisition device from the acquisition area, so as to facilitate users to understand the state of the fingerprint acquisition device, which is beneficial to improving the intuitiveness of fingerprint recognition and the user experience. Specifically, when the fingerprint acquisition device works, the light-emitting layer 220 emits light, and the light penetrates the acquisition layer 210 and illuminates the fingerprint on the user's finger and part of the light is emitted from the outside 310 of the user's finger, so that users and other observers can identify the fingerprint recognition result.

[0038] In some embodiments of this application, please continue to refer to Figure 1 , on the side of the acquisition layer 210 facing away from the light-emitting layer 220, a fingerprint pattern layer 211 is provided. The fingerprint pattern layer 211 partially covers the acquisition layer 210, and a gap part is provided on the fingerprint pattern layer 211, and the gap part exposes the acquisition layer 210.

[0039] It should be noted that in this design, a fingerprint pattern layer 211 is provided on the side of the acquisition layer 210 facing away from the light-emitting layer 220. That is to say, the fingerprint pattern layer 211 is a layer structure attached to the acquisition layer 210, and the fingerprint pattern layer 211 can be attached to the acquisition layer 210 by means such as printing, coating, or pasting. The fingerprint pattern layer 211 is not used for actual fingerprint acquisition, but serves as a guide or reference when the user places a finger. It partially covers the acquisition layer 210, which means that not the entire acquisition area is occupied by the fingerprint pattern layer 211. Gap portions are provided on the fingerprint pattern layer 211, and these gap portions expose the acquisition layer 210 to increase the light-emitting area. Moreover, the gap portions and the fingerprint pattern form a contrast between light and non-light emission, which is beneficial to improving the intuitiveness of visual guidance, helping the user to correctly place the finger; at the same time, it can also enhance the user's perception of the finger placement position and reduce misoperations.

[0040] In some other embodiments, at least a part of the acquisition layer 210 is a fingerprint pattern structure, a light-transmitting portion is provided inside the fingerprint pattern structure, a light-transmitting structure 212 is distributed outside the fingerprint pattern structure, and the light-transmitting portion is connected to the light-transmitting structure 212.

[0041] It should be noted that in this embodiment, a part of the structure of the acquisition layer 210 is set as a non-transparent structure, and the non-transparent structure shows a fingerprint pattern. That is to say, the fingerprint pattern structure is a part of the acquisition layer 210.

[0042] In some embodiments, the light-transmitting structure 212 is made of a transparent or semi-transparent material. In some embodiments, the light-transmitting structure 212 is made of glass.

[0043] In some embodiments, the light-transmitting portion is made of a transparent or semi-transparent material. In some embodiments, the light-transmitting portion is made of glass.

[0044] In some embodiments of the present application, please continue to refer to Figure 2 , the fingerprint acquisition device of this embodiment further includes a light guide film 500, and the light guide film 500 is laid on the side of the acquisition layer 210 close to the light-emitting layer 220; the light-emitting direction of the light-emitting layer 220 faces the light guide film 500.

[0045] It should be noted that the light guide film 500 is a material with excellent light conduction performance, which can uniformly transmit light from a point or a line to the entire surface. In the fingerprint acquisition device, the light guide film 500 is laid on the side of the acquisition layer 210 close to the light emitting layer 220. Its main function is to receive the light from the light emitting layer 220 and uniformly distribute it on the acquisition layer 210, thereby illuminating the user's fingerprint. The light emitting direction of the light emitting layer 220 is designed to face the light guide film 500. This means that the light generated by the light emitting layer 220 will directly irradiate the light guide film 500, rather than directly irradiating the acquisition layer 210 or the user's finger. This design helps to reduce light scattering and loss and improve the utilization efficiency of light.

[0046] It can be understood that when the light emitting layer 220 emits light, these lights will first irradiate the light guide film 500. The light guide film 500 uses its internal optical structure to uniformly transmit the light to the entire surface. Due to the excellent light guiding performance of the light guide film 500, it can ensure that the light does not undergo obvious attenuation or deflection during the transmission process. Therefore, when the light reaches the acquisition layer 210, they will form a uniform and high-intensity light illumination.

[0047] In some embodiments, the light guide film 500 is made of a white material.

[0048] In some embodiments, the housing 100 is made of a plastic material.

[0049] In some embodiments of the present application, please continue to refer to Figure 2 , the fingerprint acquisition device of this embodiment further includes a circuit board 400, and the circuit board 400 is accommodated in the housing 100; the circuit board 400 is disposed at an interval from the acquisition layer 210, and the light emitting layer 220 is disposed on the circuit board 400.

[0050] It should be noted that the introduction of the circuit board 400 provides the necessary electronic control and signal processing functions for the entire device. The circuit board 400 is one of the core components of the fingerprint acquisition device. It is responsible for controlling the switch of the light emitting layer 220, transmitting the fingerprint information captured by the acquisition layer 210, and communicating with other electronic devices (such as a processor, a memory, etc.). The circuit board 400 is accommodated in the housing 100 to ensure its protection and avoid external interference.

[0051] The light emitting layer 220 is disposed on the circuit board 400, which means that the working state (such as switch, brightness adjustment, etc.) of the light emitting layer 220 is controlled by the electronic components and circuits on the circuit board 400. The connection between the light emitting layer 220 and the circuit board 400 is usually achieved by means of welding, plugging or a flexible circuit board 400, etc., to ensure stable connection and signal transmission between the two.

[0052] An algorithm MCU chip 700 is provided on the circuit board 400. Thus, the circuit board 400 not only controls the working state of the light-emitting layer 220, but also is responsible for receiving and processing the fingerprint information captured by the acquisition layer 210. After the acquisition layer 210 converts the fingerprint information into electrical signals, these signals are transmitted to the circuit board 400 for further processing and analysis. The processor or microcontroller on the circuit board 400 will perform processing such as filtering, amplifying, and digitizing these signals to extract the characteristic information of the fingerprint.

[0053] The circuit board 400 is also responsible for communicating with other electronic devices to transmit fingerprint information or receive control instructions. This is usually achieved through wired (such as USB, serial port, etc.) or wireless (such as Bluetooth, Wi-Fi, etc.) communication methods. Corresponding interfaces and communication modules are provided on the circuit board 400 to ensure compatibility and stability with other devices. Exemplarily, a connector 600 is provided on the circuit board 400 for connecting to external devices.

[0054] In some embodiments, fixing posts 800 are provided on the circuit board 400, and the other ends of the fixing posts 800 are used to support the acquisition layer 210. A certain interval is maintained between the circuit board 400 and the acquisition layer 210, which is to ensure electrical isolation between the two and avoid mutual interference. This interval setting is usually achieved through a support structure (such as the fixing posts 800) or isolation material inside the housing 100. At the same time, the interval setting also helps with heat dissipation, preventing the heat generated by the circuit board 400 during operation from having an adverse effect on the acquisition layer 210.

[0055] In some embodiments of the present application, please continue to refer to Figure 2 , in this embodiment, the light-emitting layer 220 is provided on the side of the circuit board 400 close to the acquisition layer 210. When the light-emitting layer 220 is provided on the side of the circuit board 400 close to the acquisition layer 210, the light will directly irradiate the acquisition layer 210 without passing through an additional transmission path. This design simplifies the light transmission process, reduces light loss and scattering, and thus improves the light utilization efficiency.

[0056] In some other embodiments, the light-emitting layer 220 is disposed on the side of the circuit board 400 away from the collection layer 210. The circuit board 400 is provided with vias, and the light-emitting layer 220 emits light along the vias. Since other electronic components are usually disposed on the side of the circuit board 400 away from the collection layer 210, disposing the light-emitting layer 220 on the side of the circuit board 400 away from the collection layer 210 can more effectively utilize the space inside the housing 100. This helps to reduce the volume and weight of the device and improve portability. And after disposing the light-emitting layer 220 on the side of the circuit board 400 away from the collection layer 210, due to the certain thickness of the circuit board 400, the gap distance between the circuit board 400 and the collection layer 210 can be reduced to a certain extent, and the distance between the light-emitting layer 220 and the collection layer 210 can still be ensured to remain unchanged, which is beneficial to improving the space utilization rate of the fingerprint collection device.

[0057] In some embodiments of the present application, please continue to refer to Figure 2 , the fingerprint collection device of this embodiment further includes a fixing ring 300 connected to the housing 100. The fixing ring 300 is wound around the periphery of the collection layer 210 and fixes the collection layer 210.

[0058] It should be explained that the main function of the fixing ring 300 is to fix the collection layer 210 to prevent it from moving or deforming during operation, so as to ensure the accuracy and stability of the collection. Due to the presence of the fixing ring 300, the collection layer 210 can maintain a stable position and shape during operation. This helps to ensure that the collection layer 210 can accurately capture the fingerprint information of the user and improve the accuracy and reliability of the recognition. At the same time, the fixing ring 300 can also reduce the gap between the collection layer 210 and the housing 100 to prevent the influence of light leakage or external interference on the collection process.

[0059] In some embodiments, the fixing ring 300 is made of a metal material.

[0060] In some embodiments of the present application, please refer to Figure 3 and Figure 4 , Figure 3 shows a schematic structural diagram of the fingerprint collection device provided in this embodiment, Figure 4 shows the provided in this embodiment Figure 3 cross-sectional view taken along line A-A. The outer side 310 of the fixing ring 300 of this embodiment is connected to the housing 100. The inner side 320 of the fixing ring 300 extends to the side of the collection layer 210 away from the light-emitting layer 220, and the inner side 320 of the fixing ring 300 presses on the collection layer 210; the fixing ring 300 has a first surface facing away from the collection layer 210. Along the first direction a, the distance between the first surface and the collection layer 210 gradually decreases. The first direction a is the direction from any point on the outer side 310 of the fixing ring 300 to the nearest point on the inner side 320 of the fixing ring 300.

[0061] It should be noted that the fixing ring 300 has a first surface facing away from the acquisition layer 210. Along the first direction a, that is, the direction from any point on the outer side 310 of the fixing ring 300 to the nearest point on the inner side 320 of the fixing ring 300, the distance between the first surface and the acquisition layer 210 gradually decreases. This gradient design enables the fixing ring 300 to generate a gradually increasing pressure when fixing the acquisition layer 210, thereby ensuring the stable position of the acquisition layer 210 within the fixing ring 300 and reducing the acquisition error caused by improper fixing. Moreover, it is equivalent to the fixing ring 300 being able to form a buffer area by being recessed, and the buffer area is arranged outside the acquisition layer 210, which can improve the user experience for users with relatively large fingers or long nails.

[0062] In some embodiments of the present application, please continue to refer to Figure 1 and Figure 3 , the exposed part of the acquisition layer 210 in the opening forms a circular or rectangular structure.

[0063] In some embodiments of the present application, the light-emitting layer 220 is configured to emit multiple colors of light. The multiple colors of light at least include a first color light, a second color light, and a third color light. The light-emitting layer 220 is configured to emit the first color light when the acquisition structure 200 does not detect a fingerprint; and the light-emitting layer 220 is configured to emit the second color light when the acquisition structure 200 acquires an authorized fingerprint; and the light-emitting layer 220 is configured to emit the third color light when the acquisition structure 200 acquires an unauthorized fingerprint.

[0064] It should be noted that when the acquisition structure 200 does not detect a fingerprint, the light-emitting layer 220 emits the first color light. This is usually a prompt light, indicating that the device is currently in a standby state or waiting for the user to perform fingerprint acquisition. The first color light can be blue, green, or other soft colors to provide a user-friendly prompt. When the acquisition structure 200 acquires an authorized fingerprint, the light-emitting layer 220 emits the second color light. This is usually a confirmation light, indicating that the user's fingerprint has been successfully recognized and the device has performed corresponding operations (such as unlocking, logging in, etc.). The second color light can be green or other colors indicating success and security. When the acquisition structure 200 acquires an unauthorized fingerprint, the light-emitting layer 220 emits the third color light. This is usually a warning light, indicating that the user's fingerprint has not been recognized or is not allowed to access the device. The third color light can be red or other colors indicating error and warning.

[0065] By emitting light of different colors, the light-emitting layer 220 provides users with intuitive and easy-to-understand feedback. Users can judge the status of the device and whether their operations are successful based on the color of the light-emitting layer 220. This design not only improves the user experience but also enhances the safety and reliability of the device. In terms of safety, the colored light can also serve as an additional safety measure. For example, when the device detects an unauthorized fingerprint, in addition to emitting a warning light, it can also trigger other safety measures (such as alarm, locking, etc.). In this way, even if the device is illegally accessed, users can receive a warning immediately and take corresponding countermeasures.

[0066] In some embodiments, the light-emitting layer 220 includes a three-color light that can emit three colors of light: red, green, and blue.

[0067] In a specific embodiment, when the fingerprint collection device is in use, the fingerprint collection device can be connected to an Android device, a Windows device, the main board of a fingerprint lock, or other terminal devices through a connector 600 and a data cable. When the fingerprint collection device is in the initialization state (no fingerprints are entered), the three-color light acts as a blue breathing light and emits blue light. At this time, any fingerprint can be successfully matched. On the Android device, Windows device, and the main board of the fingerprint lock, operate according to the device requirements, follow the device instructions or the device prompt sound, enter the administrator fingerprint, and then enter different finger fingerprints again to exit the input state.

[0068] When a non-entered fingerprint is placed on the collection layer 210, the collection layer 210 will turn red at this time. When using the area of an entered fingerprint, the collection layer 210 will turn green at this time. When no fingerprint is placed in the pattern area, there will be a blue breathing color. After the fingerprint module enters the correct fingerprint, the fingerprint will be saved in the fingerprint module. The finger can be directly placed into the collection layer 210. The fingerprint collection device can judge the status of the fingerprint. For a non-entered fingerprint, the collection layer 210 will turn red, and for an entered fingerprint, the collection layer 210 will turn green.
