In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

Please refer to FIGS. 1A and 1B, where FIG. 1A is an exploded view of a fingerprint recognition module according to an embodiment of the present invention, and FIG. 1B is a functional block diagram of the fingerprint recognition module according to FIG. 1A. As shown in FIGS. 1A and 1B, the fingerprint recognition module 100 may include a touch surface 101, a touch detection component 102, a fingerprint capture component 103, a feedback component 104 and a processing component 105.

In different embodiments, the touch surface 101 can be implemented as glass, plastic or other similar materials, and can be used to withstand a touch operation. The aforementioned touch operation may be a click operation or a sliding operation applied by the user with the finger 199 on the touch surface 101, but the present invention is not limited to this. In FIG. 1A, the touch surface 101 can cover the touch detection element 102 and the fingerprint capture element 103. Moreover, the touch surface 101 may be a flat surface, that is, no buttons or other fingerprint recognition mechanisms that can be observed from the appearance are not provided. Furthermore, the touch surface 101 may be a non-display area, that is, it cannot be used to display complex visual content or multimedia content such as images and movies like a screen.

In this embodiment, the touch detection element 102 is coupled to the processing element 105, and may include a first detection area 102a and a second detection area 102b. The first detection area 102a and the second detection area 102b can be used to detect the current position of the touch operation on the touch surface 101 when the touch surface 101 receives a touch operation. In other embodiments, the touch detection element 102 may also include only one of the first detection area 102a and the second detection area 102b to detect the current position of the touch operation on the touch surface 101, and It is not limited to the aspect shown in FIG. 1A.

The fingerprint capture element 103 is coupled to the processing element 105 and is adjacent to the touch detection element 102. In the embodiment of FIG. 1A, the fingerprint capture element 103 can be disposed between the first detection area 102a and the second detection area 102b, and can be used to capture fingerprints. For example, if the user applies a sliding operation on the touch surface 101 with a finger 199, and the sliding operation slides over the position corresponding to the fingerprint capture element 103 on the touch surface 101, the fingerprint capture element 103 can slide as described above The fingerprint of finger 199 is captured when the operation passes. For another example, if the user applies a click operation with the finger 199 on the touch surface 101 at a position corresponding to the fingerprint capture element 103, the fingerprint capture element 103 can also capture the fingerprint of the finger 199 accordingly. The invention may not be limited to this.

The feedback element 104 is coupled to the processing element 105, and can provide a first feedback and/or a second feedback in response to a touch operation applied by the user. In the embodiment of FIG. 1A, the feedback element 104 may include a first sub-element 104a and a second sub-element 104b, which may be implemented as light sources for providing light with a specific color as the first feedback and/or the second feedback, respectively. , But the present invention may not be limited to this. In other embodiments, the feedback element 104 can also be implemented as a module having elements such as a light guide layer, a filter element, a light source array, etc. according to the needs of the designer, so as to provide more diversified light patterns. In the embodiment of FIG. 1A, the touch surface 101 may be provided with a light-transmitting area 101a, which can be used to allow the light source provided by the feedback element 104 to pass through, but it is not limited to this.

For example, in an initial state where the touch surface 101 has not yet undergone a touch operation, the first sub-element 104 a and the second sub-element 104 b may cooperate to provide a first color (for example, yellow) as the first feedback. In this case, the user in FIG. 1A can observe that the light-transmitting area 101a presents the first color as a whole.

In one embodiment, if the touch operation is a click operation, when the click operation is applied to the fingerprint capture element 103, the first sub-element 104a and the second sub-element 104b can cooperate to provide a second color (for example , Blue) as the second feedback. In this case, the user in FIG. 1A can observe that the light-transmitting area 101a is changed to the aforementioned second color as a whole.

In another embodiment, if the touch operation is a sliding operation, the first sub-element 104a and the second sub-element 104b can provide the second color at the position passed by the sliding operation as the second feedback. In this case, the user in FIG. 1A can see on the light-transmitting area 101a that all the areas where the sliding operation passes are changed to the second color, but the areas where the sliding operation has not passed still maintain the first color.

In other embodiments, the feedback element 102 may also include only one of the first sub-element 104a and the second sub-element 104b to change the color of the light provided in response to the user's touch operation. As a first feedback and/or a second feedback.

In addition, in other embodiments, the feedback element 104 (and its first sub-element 104a and second sub-element 104b) can also be implemented to provide specific sounds, patterns, and information in response to the user's touch operation. The element is used as the first feedback and/or the second feedback, and is not limited to an element that can only provide light.

In different embodiments, the processing element 105 can be a general purpose processor, a special purpose processor, a traditional processor, a digital signal processor, multiple microprocessors, one or more combined digital signal processors The core microprocessors, controllers, microcontrollers, application specific integrated circuits (ASIC), field programmable gate array circuits (Field Programmable Gate Array, FPGA), any other types of integrated circuits, status Machines, processors based on Advanced RISC Machines (ARM) and similar products.

In the embodiment of FIG. 1A, the fingerprint recognition module 100 may further include a printed circuit board 106, which may be used to carry other components in the fingerprint recognition module 100, but it may not be limited thereto.

In the embodiment of the present invention, the processing component 105 can make the fingerprint recognition module 100 execute the fingerprint recognition method proposed by the present invention by loading specific modules, program codes, etc.

Please refer to FIG. 2, which is a method for identifying biological information according to an embodiment of the present invention. The method of the present invention can be executed by the fingerprint recognition module 100 of FIG. 1A and FIG. 1B. The details of each step in FIG. 2 are described below with the content shown in FIG. 1A and FIG. 1B.

First, in step S210, the processing element 105 can control the feedback element 104 to provide the first feedback in the initial state. In one embodiment, the initial state is, for example, a state where the touch surface 101 has not received a touch operation, but it may not be limited to this. In addition, in one embodiment, the fingerprint recognition module 100 of the present invention can be installed in an electronic device to assist the electronic device in performing related fingerprint recognition to the user. Therefore, the aforementioned initial state can also be understood as a state of waiting for the user to input a fingerprint to the fingerprint recognition module 100, such as a locked state or other states that require the user to input a fingerprint for identity verification, but not limited to this.

For ease of description, the following assumes that the feedback element 104 (ie, the first sub-element 104a and the second sub-element 104b) is a light source that can provide specific light in response to a touch operation, but the embodiments of the present invention may not be limited thereto. Therefore, for the user of FIG. 1A, it can be observed that the light-transmitting area 101 a of the touch surface 101 presents the first color (ie, the first feedback).

After that, in step S220, the processing element 105 can control the touch detection element 102 to detect the touch operation performed on the touch surface 101. Specifically, the processing element 105 can control the touch detection element 102 to detect the current position of the touch operation on the touch surface 101. In different embodiments, the touch operation may be a sliding operation on the touch surface 101 or a click operation applied on the touch surface 101.

For ease of description, the following will assume that the touch operation applied by the user is a sliding operation. However, in FIG. 1A, since the area of the touch surface 101 may be larger than that of the touch detection element 102, the user may touch a position that the touch detection element 102 cannot detect. Therefore, in the embodiment of FIG. 1A, the above-mentioned touch operation can be further defined as a sliding operation of passing through the first specific position P1 on the touch surface 101 and sliding toward the fingerprint capture element 102, wherein the first specific position P1 corresponds to the touch A detectable position of the first detection area 102a of the collision detection element 102. In addition, in other embodiments, the aforementioned touch operation may also be defined as a sliding operation that passes through the second specific position P2 on the touch surface 101 and slides toward the fingerprint capture element 102, wherein the second specific position P2 corresponds to the touch A detectable position of the second detection area 102b of the collision detection element 102.

From another point of view, the first specific position P1 and the second specific position P2 can also be roughly understood as being located at both ends of the light-transmitting region 101a. That is, the first feedback provided by the feedback element 104 can be understood as being present between the first specific position P1 and the second specific position P2.

Then, in step S230, the processing element 105 can control the feedback element 104 to provide a second feedback between the first specific position P1 and the current position. To make this step easier to understand, the following will be supplemented with Figure 3 for further explanation.

Please refer to FIG. 3, which is an application scenario diagram drawn according to an embodiment of the present invention. In the state 301 of this embodiment, it is assumed that the user is about to use the finger 199 to apply a sliding operation to the touch surface 101 that passes through the first specific position P1 and slides toward the fingerprint capture element 103. When the aforementioned touch operation has not been received, the feedback element (not separately labeled) can provide a first feedback F1 (for example, yellow light).

Thereafter, in the state 302, the processing element 105 may control the feedback element 104 to provide a second feedback F2 (for example, blue light) between the first specific position P1 and the current position 310. At the same time, in order to maintain the first feedback F1 where the touch operation has not passed, the processing element 105 can control the feedback element 104 to provide the first feedback F1 between the current position 310 and the second specific position P2 on the touch surface 101.

Therefore, for the user, they can observe the visual feedback provided by the fingerprint recognition module 100 following the movement of the touch operation.

Then, in step S240, the processing component 105 can control the fingerprint capturing component 103 to capture the user's fingerprint when receiving the touch operation. Taking FIG. 3 as an example again, in the state 302, when the touch operation shown is slid to the position on the touch surface 101 corresponding to the fingerprint capture element 103, the fingerprint capture element 103 can be controlled to capture the user Fingerprint of 199. At the same time, as the touch operation continues to slide to the second specific position P2, the second feedback F2 (for example, blue light) provided by the feedback element 104 will also change accordingly, as shown in the state 303.

After capturing the user's fingerprint, in step S250, the processing element 105 may perform a fingerprint recognition operation based on the fingerprint. For example, the processing component 105 may compare the captured fingerprints with the fingerprints of the legal users recorded in the database, and if they match, determine that the user of the finger 199 is a legal user. In one embodiment, after determining that the user is a legal user, the electronic device provided with the fingerprint recognition module 100 can perform operations such as unlocking or authorization accordingly, but it is not limited to this.

It can be seen from the above that the electronic device with the biological information recognition module and the method proposed by the present invention can provide corresponding feedback according to the touch operation input by the user on the touch surface, thereby providing the user with a novel operating experience. And, different from the conventional technique in which the fingerprint recognition module is integrated into the display area, the fingerprint recognition module of the present invention can be installed in the non-display area of the electronic device, so that it can be used without occupying the display area. Better use of the area in the electronic device.

That is, the fingerprint recognition module 100 is disposed in a non-display area of the electronic device 400 (for example, the frame of the display 410).

In addition, as shown in FIG. 4, when the electronic device 400 is in an initial state (such as the locked mode shown), the fingerprint recognition module 101 can be controlled to provide the first information IS1. In this embodiment, the first information IS1 is, for example, a pattern controlled by a light source array (such as an LED light source array) in the feedback element (not separately labeled), such as a fingerprint pattern to prompt the user to input a fingerprint. In other embodiments, the above-mentioned pattern may also be a specific figure or symbol, but the present invention may not be limited thereto.

In FIG. 4, when the user's fingerprint passes through the fingerprint recognition operation of the electronic device 400, the electronic device 400 can be loaded into the operating system accordingly to execute the working mode, and the fingerprint recognition module 101 can be controlled to provide second information IS2. In this embodiment, the second information IS2 is, for example, a pattern controlled by the light source array in the feedback element, which is, for example, a trademark of the electronic device 400. In other embodiments, the second information IS2 may also be weather or other information that may be of interest to users, such as stock information, specific patterns, communication software information, etc., but it is not limited to this.

In other embodiments, the fingerprint recognition module 100 can also be changed to be disposed in the touchpad area of the electronic device 400, under the keyboard keys, at the trademark of the body shell, or at the appearance shaft, but it is not limited to this.

Then, when the user inputs a sliding operation from left to right on the touch surface 101 with his finger 799, the touch surface 101 can sequentially provide the second information IS72, IS73, and IS74 in response to the sliding operation. In FIG. 7, the second information IS72 to IS74 are, for example, characters in the trademark of the electronic device 400. That is, for the user, during the process of inputting a sliding operation on the touch surface 101, they can observe that the touch surface 101 sequentially displays the trademark characters of the electronic device 400 along with the position reached by the sliding operation.
