[0048] In the following description and claims, some indications such as "upper", "lower", "before", "after", "previous", "after", etc. may be regarded as references to the accompanying drawings. The present case is not limited thereto.

[0049] See also Figure 1A . Figure 1A FIG. 1 is a schematic diagram of a fingerprint detection device according to some embodiments of the present invention. Figure 1A As shown, in some embodiments, the fingerprint detection device 100 may include a fingerprint sensing module 110 and a processor 120. The fingerprint sensing module 110 and the processor 120 are electrically coupled to each other, so that the processor 120 can control the fingerprint sensing module 110 to capture and identify the fingerprint of at least one user.

[0050] In some embodiments, the fingerprint sensing module 110 may be a single optical sensing circuit or an integration of multiple optical sensing circuits. Figure 1AAs shown, in some embodiments, the fingerprint sensing module 110 may include a first fingerprint sensing circuit 111, a second fingerprint sensing circuit 112, a third fingerprint sensing circuit 113, and a fourth fingerprint sensing circuit 114. These fingerprint sensing circuits 111-114 can be arranged at any position according to design requirements. For example, fingerprint sensing circuits 111-114 adjacent to each other can be arranged under a detection surface that can sense the user's fingerprint. For example, the above-mentioned detection surface can be the surface or a part of the surface of the display panel. According to design requirements, various optical structures with different functions (for example, a lens or a waveguide grating) can be set between the detection surface and the fingerprint sensing circuits 111-114.

[0051] It should be noted that, according to some embodiments, each fingerprint sensing circuit 111-114 can be implemented by various optical sensing units, such as a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) photosensitive element. When light passes through the optical structure (such as a lens or a waveguide grating) on ​​the fingerprint sensing circuit 111-114, the fingerprint sensing circuits 111-114 can respectively capture optical information and perform sensing within their respective fields of view. The size of the field of view that each fingerprint sensing circuit 111-114 can sense affects the detection area that a single fingerprint sensing circuit can be responsible for. In this method in the present embodiment, using multiple fingerprint sensing circuits 111-114 to perform sensing together can capture optical information within a wider field of view (relative to the field of view of a single fingerprint sensing circuit).

[0052] In some embodiments, the fingerprint sensing circuits 111-114 are electrically coupled to the processor 120 via a shared transmission bus (e.g., a Serial Peripheral Interface (SPI) port 120A). In other words, the processor 120 has a SPI port 120A as an input port, and the SPI port 120A is used to receive the fingerprint image captured by the fingerprint sensing circuits 111-114. Using a single input port (e.g., a SPI port) on the processor 120 can save the number of input ports of the processor, the number of transmission lines between the processor and the fingerprint sensing circuits 111-114, and reduce the complexity of the wiring of the transmission lines.

[0053] However, it should be noted that the aforementioned embodiments are not intended to limit the scope of the present invention. In some embodiments, the fingerprint sensing module 110 can be implemented by a single optical sensing circuit with high power and a relatively wide field of view, so that the field of view of the single optical sensing circuit of the fingerprint sensing module 110 can also cover the equivalent Figure 1A The total detection area of ​​the fingerprint sensing circuits 111-114 is responsible for.

[0054] In some embodiments, the processor 120 may include but is not limited to a single processor or an integration of multiple microprocessors, such as an application-specific integrated circuit (ASIC) or other similar processing circuits. In some embodiments, the processor 120 may be connected to some memory (not shown). In this way, the processor 120 can access specific computer-readable instructions and execute computer-readable instructions to execute at least one application to complete the function of the fingerprint detection device 100, which can be a method for capturing and identifying a user's fingerprint. In order to better understand the present case, the details of the application executed by the processor 120 will be described in detail in the following paragraphs.

[0055] In some embodiments, the memory may include but is not limited to at least one flash memory, a mechanical hard disk (HDD), a solid-state drive (SSD), a dynamic random access memory (DRAM), and a static random access memory or a combination of the above memories. In some embodiments, the memory can be used as a non-transitory computer-readable medium, and the memory stores some computer-readable instructions. The processor 120 can access the above memory and execute the computer-readable instructions therein.

[0056] Figure 1B FIG. 1 is a schematic diagram of a fingerprint detection device according to some embodiments of the present invention. A possible configuration of the fingerprint sensing circuits 111-114 is as follows: Figure 1B See also Figure 1AEmbodiment. This design indicates that the fingerprint sensing circuits 111-114 are configured on the top surface of the chip. Each fingerprint sensing circuit 111-114 is coupled to the processor 120 via the serial peripheral interface port 120A. A lens module LM is provided at an upper position aligned with the fingerprint sensing circuits 111-114. It should be noted that the lens module LM and the fingerprint sensing circuits 111-114 are both buried under a portion of the pixels of the display 200. According to this arrangement, external light can penetrate the display 200 and be reflected by the lens module LM and projected to the fingerprint sensing circuits 111-114, and the fingerprint sensing circuits 111-114 can capture the reflected light from the surface of the display 200.

[0057] Figure 1C It is a schematic diagram of a fingerprint detection device drawn according to some embodiments of the present case. Figure 1C The possible configuration of multiple modules (in blocks) in the fingerprint detection device is schematically illustrated. Figure 1A as well as Figure 1B The SPI port 120A in the processor 120 is coupled to the fingerprint sensing module 120B, so that the processor 120 can receive the images captured by the fingerprint sensing circuits 111-114 of the fingerprint sensing module 120B.

[0058] exist Figure 1C In an embodiment, the processor 120 is also coupled to the touch sensing module 300. The touch sensing module 300 can be a device including multiple touch sensing electrodes on the display 200 for detecting the contact of the user's finger. The contact of the user's finger can be used to determine the fingerprint transmission order of the fingerprint sensing module 120B. The processor 120 includes an unlocking recording module 120C, a data processing module 120D and a capture control module 120E. The unlocking recording module 120C is used to store the fingerprint detection sequence that triggers successful unlocking. The data processing module 120D is used to determine whether the captured image can trigger a successful unlocking. The capture control module 120E is used to control the transmission order of the fingerprint sensing module 120B. It should be noted that the detailed functions of these modules will be further explained in subsequent embodiments.

[0059] Please read further Figure 2A as well as Figure 2B . Figure 2A as well as Figure 2B It is a schematic diagram of a fingerprint detection device drawn according to some embodiments of the present case. Figure 2A The appearance of the fingerprint detection device FD is presented. Figure 2A As shown, in some embodiments, the fingerprint detection device FD may be, but is not limited to, a mobile phone including a display 200 .

[0060] Figure 2B According to some embodiments, at least a portion of the interior of the fingerprint detection device FD is presented. Figure 1B .like Figure 2B As shown, in some embodiments, the fingerprint detection device FD further includes a touch sensing module 300 (with Figure 1B The touch sensing module 300 may include a plurality of touch sensing electrodes, such as common mode electrodes, distributed under the display device 200. Figure 2B As shown, Figure 1A The fingerprint detection device 100 in the embodiment is embedded in the fingerprint detection device FD. In such a configuration, the electrical signal of the touch sensing electrode can be transmitted to the processor 120 through at least one signal line.

[0061] It is to be understood that the above embodiments are not intended to limit the scope of the present disclosure. Any structure of a display panel that can perform fingerprint sensing (or additional touch sensing) can also be implemented. In alternative embodiments, the fingerprint detection device FD may include more parts, such as memory, inertial sensing elements, cameras, graphics processors, or central processing units. In this way, the fingerprint detection device FD can perform more functions in addition to fingerprint detection. In some embodiments, the processor 120 can be the central processing unit (or application processor) of the fingerprint detection device FD.

[0062] In some embodiments, the display 200 can be virtually divided into a plurality of sensing blocks. Such division can be based on the distribution of touch sensing electrodes, but the present invention is not limited thereto. For a better understanding, please refer to Figure 3A , Figure 3A FIG. 1 is a schematic diagram of a fingerprint detection device according to some embodiments of the present invention. Figure 3A In the front view of the display 200 shown in FIG. 1 , the display 200 can be virtually divided into 512 (i.e., divided into 16 columns and 32 rows) sensing blocks. In some embodiments, the touch sensing electrodes of the touch sensing module 300 can be used to detect the user's touch on the display 200. Once the user touches the sensing block of the display 200, the touch sensing electrodes under the sensing block can transmit an electrical signal to the processor 120. In this way, the processor 120 can instruct the fingerprint sensing module to detect the corresponding area or block of the display 200 touched by the user.

[0063] In some embodiments, a specific area of ​​the display 200 may be used to detect and recognize a user's fingerprint. Figure 3B , Figure 3B FIG. 1 is a schematic diagram of a fingerprint detection device according to some embodiments of the present invention. Figure 3BThe four sensing regions shown are the first sensing region SZ1, the second sensing region SZ2, the third sensing region SZ3 and the fourth sensing region SZ4 which are substantially arranged in the middle of the display 200, and each of the sensing regions SZ1-SZ4 includes a plurality of sensing blocks of the display 200 (for example, the sensing region SZ1 includes four sensing blocks on the display 200, the sensing region SZ2 includes another four sensing blocks on the display 200, and so on). However, it can be understood that the number of sensing regions and the positions of the sensing regions are not limited to this embodiment.

[0064] In some embodiments, Figure 2B The fingerprint sensing circuits 111-114 in the display 200 are arranged under the sensing areas SZ1-SZ4 so as to detect the fingerprint of the user through the display 200. Specifically, in some embodiments, the first fingerprint sensing circuit 111 is arranged under the first sensing area SZ1, the second fingerprint sensing circuit 112 is arranged under the second sensing area SZ2, the third fingerprint sensing circuit 113 is arranged under the third sensing area SZ3, and the fourth fingerprint sensing circuit 114 is arranged under the fourth sensing area SZ4. According to such a configuration, when the user's finger falls on the sensing area SZ1-SZ4 on the display 200, the fingerprint sensing module 110 can detect the user's fingerprint.

[0065] Figure 4A Flowchart of a fingerprint detection method according to some embodiments of the present invention. Figure 1A The fingerprint detection device 100 may perform Figure 4A Therefore, you can refer to the fingerprint detection method in Figure 1A , Figure 2A , Figure 2B , Figure 3A as well as Figure 3B The detailed steps S1-S7 of the fingerprint detection method will be more clearly described in the subsequent paragraphs. It should be noted that, in some embodiments, the processor 120 of the fingerprint detection device 100 can be used to perform the subsequent steps S1-S7.

[0066] Step S1: receiving the touch area information of each sensing area.

[0067] As mentioned above, in some embodiments, the processor 120 can receive information about the touch area of ​​each sensing zone SZ1-SZ4. Figure 5A . Figure 5A According to some embodiments of the present invention, Figure 3B An example of the touch area of ​​the sensing zones SZ1-SZ4. Figure 5AIn the example of FIG. 1 , when a user's finger (eg, thumb) touches the sensing areas SZ1 , SZ3 , and SZ4 , the touch areas of the sensing areas SZ1 - SZ4 are as shown in the following Table 1:

[0068]

[0069] Table 1

[0070] like Figure 5A As shown in Table 1, the touch areas of the sensing areas SZ1-SZ4 reflect how the user touches the display 200. In some embodiments, the user touches three of the four blocks in the sensing area SZ1, one of the four blocks in the sensing area SZ3, and all of the four blocks in the sensing area SZ4.

[0071] However, it is understood that the above embodiments are not intended to limit the scope of the present invention. The processor 120 may calculate the touch area of ​​each sensing area in different ways depending on different hardware configurations or software configurations. For example, assuming that the touch sensing electrodes of the touch sensing module 300 can sense more details on the display 200, the touch area of ​​each sensing area may be calculated to a more accurate degree.

[0072] Step S2: Determine the transmission order according to the touch area of ​​each sensing area.

[0073] like Figure 1B As described in the embodiment of FIG. 1 , in some embodiments, the fingerprint sensing circuits 111-114 are electrically coupled to the processor 120 via a shared transmission bus (e.g., a serial peripheral interface bus). Therefore, in order to avoid conflicts between multiple sensing information during transmission, the processor 120 can control the fingerprint sensing circuits 111-114 to transmit their respective sensing information according to a specific transmission order.

[0074] In some embodiments, the transmission order is determined based on the order of the size of the touch area in the sensing area SZ1-SZ4. It should be noted that a larger touch area in the sensing area SZ1-SZ4 can provide more information for fingerprint authentication. Therefore, data from the sensing area SZ1-SZ4 with a larger touch area can be arranged at a higher priority in the transmission order. When the processor 120 receives the touch areas of the sensing areas SZ1-SZ4, the processor 120 can place the fingerprint sensing circuit corresponding to the sensing area with a larger touch area at a higher priority in the transmission order, and the fingerprint sensing circuits of other sensing areas with a smaller touch area can be placed at a lower priority in the transmission order.

[0075] like Figure 5AAs shown in Table 1, the sensing area SZ4 has the largest touch area (4 blocks), so that the transmission order of the fourth fingerprint sensing circuit 114 is in the first order (the transmission order of the fourth fingerprint sensing circuit 114 takes precedence over the transmission order of the other three fingerprint sensing circuits 111-113). The sensing area SZ1 has the second largest touch area (3 blocks), so that the transmission order of the first fingerprint sensing circuit 111 is in the second order (the transmission order of the first fingerprint sensing circuit 111 takes precedence over the transmission order of the second fingerprint sensing circuit and the third fingerprint sensing circuit). The sensing area SZ3 has the third largest touch area (1 block), so that the transmission order of the third fingerprint sensing circuit 113 is in the third order (the transmission order of the third fingerprint sensing circuit 113 takes precedence over the transmission order of the second fingerprint sensing circuit 112). The sensing area SZ2 has the smallest touch area (0 blocks), so that the transmission order of the second fingerprint sensing circuit 112 is in the last order. Figure 5A In the illustrated embodiment, the transmission order may be determined as first the fourth fingerprint sensing circuit 114 , then the first fingerprint sensing circuit 111 , then the third fingerprint sensing circuit 113 , and finally the second fingerprint sensing circuit 112 .

[0076] In such a situation, the processor 120 can obtain valuable key information (including more touch area) from the fourth fingerprint sensing circuit 114 more quickly than other fingerprint sensing circuits.

[0077] See also Figure 5B . Figure 5B According to some embodiments of the present invention, Figure 3B Another example of the touch area of ​​the sensing zones SZ1-SZ4. Figure 5B In the example of FIG. 1 , when the user's thumb touches the sensing areas SZ2 , SZ3 , and SZ4 , the touch areas of the sensing areas SZ1 - SZ4 are as shown in the following Table 2:

[0078]

[0079] Table 2

[0080] exist Figure 5B In the embodiment shown, the transmission order can be determined as first the third fingerprint sensing circuit 113, then the fourth fingerprint sensing circuit 114, then the second fingerprint sensing circuit 112, and finally the first fingerprint sensing circuit 111. In other words, the transmission order can be determined according to the order of the size of the touched area in the sensing zones SZ1-SZ4.

[0081] like Figure 5A and Figure 5BIn the above-mentioned embodiment shown, the touch areas of the sensing areas SZ1-SZ4 are different from each other, so that the transmission order is determined according to the order of the size of the touch areas. However, the present invention is not limited to this. In some embodiments, the touch areas of any two or more of the sensing areas SZ1-SZ4 may have the same size. In such an embodiment, additional information may be considered to determine the transmission order. For example, the transmission order may be determined by referring to the success rate of recognition, but the present invention is not limited to this. Please refer to further Figure 4B . Figure 4B According to some embodiments of the present invention, Figure 4A Flow chart of further steps S21-S26 in step S2.

[0082] like Figure 1C as well as Figure 4B As shown, step S21 is executed by the processor 120 to compare the sizes of the touch areas in the sensing areas SZ1-SZ4. Step S22 is executed by the processor 120 to determine whether the touch areas of at least two of the sensing areas SZ1-SZ4 have the same size. In response to the sizes of all the touch areas in the sensing areas SZ1-SZ4 being different, for example, in the aforementioned Figure 5A In conjunction with the embodiment of Table 1 and in the aforementioned Figure 5B In conjunction with the embodiment of Table 2, step S23 is executed by the processor 120 to determine the transmission order between the sensing areas SZ1-SZ4 according to the order of the size of the touched areas. Figure 5A In conjunction with the embodiment of Table 1 and in the aforementioned Figure 5B The embodiment of Table 2 has been described and will not be repeated here.

[0083] When the touch areas of at least two of the sensing regions SZ1-SZ4 are the same, steps S24-S26 are executed to determine the transmission order between the sensing regions SZ1-SZ4. Figure 5C . Figure 5C According to some embodiments of the present invention, Figure 3B Another example of the touch area of ​​the sensing zones SZ1-SZ4. Figure 5C In the example of FIG. 1 , when the user's thumb touches the sensing areas SZ1 , SZ2 , and SZ3 , the touch areas of the sensing areas SZ1 - SZ4 are as shown in the following Table 3:

[0084]

[0085] Table 3

[0086] like Figure 5CAs shown in Table 3, the sensing areas SZ1 and SZ2 have the same touch area (2 blocks), the sensing area SZ3 has a smaller touch area (1 block), and the sensing area SZ4 has the smallest touch area (0 blocks). Step S24 is executed by the processor 120 to determine the preliminary result of the transmission sequence between the sensing areas SZ1-SZ4 according to the order of the size of the touch area. In the preliminary result of the transmission sequence, the transmission sequence of the first fingerprint sensing circuit 111 (corresponding to the sensing area SZ1) and the second fingerprint sensing circuit 112 (corresponding to the sensing area SZ2) are both in the first order. In addition, the transmission sequence of the third fingerprint sensing circuit 113 (corresponding to the sensing area SZ3) is in the third order, and the transmission sequence of the fourth fingerprint sensing circuit 114 (corresponding to the sensing area SZ4) is in the fourth order.

[0087] In some embodiments, for two sensing areas SZ1 and SZ2 having the same touch area, the processor 120 can determine the positions of these sensing areas in the transmission sequence according to the recognition success ratios of the sensing areas SZ1 and SZ2. In some embodiments, the recognition success ratio of a sensing area is the ratio of the fingerprint recognition success results finally obtained according to the sensing information of this sensing area.

[0088] It should be noted that Figure 4B The description is for illustrative purposes only. Any method that at least refers to the size of the sensing area and the recognition ratio can also be used to arrange the transmission order. For example, the transmission order can be arranged based on the mixing factors of the sensing area, where the mixing factor for each sensing area can be a weighted result of two factors: the size of the touch area of ​​the sensing area and the recognition success ratio of the sensing area. In some embodiments, regardless of whether there are two or more sensing areas with the same size of touch area, the size of the touch area of ​​the sensing area and the recognition success ratio of the sensing area are considered at the same time.

[0089] like Figure 4B , Figure 5C As shown in Table 3, step S25 is executed by the processor 120 to obtain the recognition success ratio of at least two sensing zones SZ1 and SZ2 having the same touch area. In some embodiments, the processor 120 may obtain the recognition success ratio of all sensing zones SZ1-SZ4.

[0090] In some embodiments, in order to obtain the recognition success rate, each time the sensing information is transmitted from the sensing area SZ1-SZ4 to the processor 120, assuming that the sensing area triggers a successful fingerprint recognition, the processor 120 can establish a count of one of the sensing areas SZ1-SZ4. For example, assuming that the processor 120 has successfully recognized the user's fingerprint using the sensing information of the first sensing area SZ1, the current count of the first sensing area SZ1 can be incremented by one. In this way, the sensing area that triggers more successful fingerprint recognitions can have a relatively large count, and a relatively large count also represents a higher recognition success rate. As shown in Table 3, it is assumed that the recognition success rates (expressed in times) of the sensing areas SZ1-SZ4 are (11, 14, 17, 4) respectively.

[0091] However, it is to be understood that the above embodiments are not intended to limit the scope of the present invention. The recognition success ratios of the sensing zones SZ1 - SZ4 may be obtained by alternative methods (eg, derived from statistical results or any other desired method).

[0092] like Figure 4B , Figure 5C As shown in Table 3, step S26 is executed by the processor 120 to determine the final result of the transmission sequence between at least two sensing areas according to the order of the recognition success ratio (for example, Figure 5C Sensing zones SZ1 and SZ2 in the illustrated embodiment).

[0093] Figure 5C And the embodiment of Table 3 gives the following conditions: the touch area of ​​the sensing areas SZ1-SZ4 is (2, 2, 1, 0) and the recognition success rate (expressed in times) of the sensing areas SZ1-SZ4 is (11, 14, 17, 4). In such a case, the first sensing area SZ1 and the second sensing area SZ2 have the largest touch area among all the sensing areas SZ1-SZ4. And, comparing the recognition success rates of the first sensing area SZ1 and the second sensing area SZ2, the second sensing area SZ2 has a higher recognition success rate. Therefore, in the final result of the transmission sequence, the processor 120 can determine that the second sensing area SZ2 has priority over the first sensing area SZ1. Then, because the touch area corresponding to the third sensing area SZ3 is larger than the touch area corresponding to the fourth sensing area SZ4, in the transmission sequence, the processor 120 can determine that the third sensing area SZ3 has priority over the fourth sensing area SZ4. In this case, the final result of the transmission sequence may be (SZ2, SZ1, SZ3, SZ4).

[0094] Please read further Figure 5D . Figure 5D According to some embodiments of the present invention, Figure 3B Another example of the touch area of ​​the sensing zones SZ1-SZ4. Figure 5D In the example of FIG. 4 , when the user's thumb touches the sensing areas SZ1 and SZ4 , the touch areas of the sensing areas SZ1 - SZ4 are as shown in the following Table 4:

[0095]

[0096] Table 4

[0097] like Figure 5D As shown in Table 4, the sensing areas SZ1 and SZ4 have the same touch area (3 blocks), and the sensing areas SZ2 and SZ3 have the same touch area (0 blocks). Step S24 is executed by the processor 120 to determine the preliminary result of the transmission sequence between the sensing areas SZ1-SZ4 according to the order of the size of the touch area. The preliminary result of the transmission sequence is as described below. The transmission sequence of the first fingerprint sensing circuit 111 (corresponding to the sensing area SZ1) and the fourth fingerprint sensing circuit 114 (corresponding to the sensing area SZ4) are both in the first order, and the transmission sequence of the second fingerprint sensing circuit 112 (corresponding to the sensing area SZ2) and the third fingerprint sensing circuit 113 (corresponding to the sensing area SZ3) are both in the third order.

[0098] like Figure 4B , Figure 5D As shown in Table 4, step S25 is executed by the processor 120 to obtain the recognition success ratio of the sensing areas SZ1 and SZ4 having the same touch area, and the sensing areas SZ2 and SZ3 have the same touch area. In some embodiments, the processor 120 can obtain the recognition success ratio of all the sensing areas SZ1-SZ4.

[0099] like Figure 4B , Figure 5D As shown in Table 4, step S26 is executed by the processor 120 to determine the final result of the transmission sequence between at least two sensing areas (for example, in the embodiment shown in FIG. 5D , the final result of the transmission sequence between sensing areas SZ1 and SZ4 , and the final result of the transmission sequence between sensing areas SZ2 and SZ3 ) according to the order of the recognition success ratios.

[0100] like Figure 5D As shown in Table 4, in the transmission sequence, the processor 120 may determine that the first sensing area SZ1 is prioritized over the fourth sensing area SZ4, and determine that the third sensing area SZ3 is prioritized over the second sensing area SZ2. In this case, the final result of the transmission sequence may be (SZ1, SZ4, SZ3, SZ2).

[0101] exist Figure 4BIn the above-mentioned embodiment, the transmission order between at least two sensing areas with the same touch area can be determined according to the recognition success ratio. However, the present invention is not limited to this. Figure 4C . Figure 4C According to some embodiments of the present invention, Figure 4A Flow chart of further steps S21-S24 and step S27 in step S2. Figure 4C Steps S21-S24 shown in FIG. 1 are similar to Figure 4B Steps S21-S24 shown in FIG. 1 are not described in detail here.

[0102] like Figure 4C As shown, after step S24, the processor 120 executes step S27 to determine the final result of the transmission sequence between at least two sensing areas with the same touch area according to the predetermined sequence. The predetermined sequence can be a predefined sequence order, for example, SZ1 is in the first sequence, SZ2 is in the second sequence, SZ3 is in the third sequence, and SZ4 is in the fourth sequence.

[0103] according to Figure 5D An embodiment of Figure 4C The final result of the transmission order determined by step S27 in is shown in the following Table 5:

[0104]

[0105] Table 5

[0106] In the corresponding Figure 5D In the transmission order determined in step S27 of the embodiment shown in Table 4, the processor 120 may determine that the first sensing area SZ1 is prioritized over the fourth sensing area SZ4 in the transmission order, and may determine that the second sensing area SZ2 is prioritized over the third sensing area SZ3 in the transmission order. In this case, the final result of the transmission order may be (SZ1, SZ4, SZ2, SZ3).

[0107] However, the above embodiments are not intended to limit the scope of the present invention. In some embodiments, assuming that the touch area of ​​the sensing area is 0 (for example, the sensing area is not touched), the processor 120 may ignore the sensing area with a touch area of ​​0 when determining the transmission order. Such a mechanism can further improve the transmission efficiency.

[0108] Step S3: Control the fingerprint sensing circuit to capture sensing information including the fingerprint pattern from the sensing area.

[0109] In some embodiments, when the user's finger touches the sensing area SZ1-SZ4 of the display 200, the optical information captured by the fingerprint sensing circuit 111-114 can contain sufficient information for the user's fingerprint authentication. Therefore, the order of step S2 and step S3 is not limited to the aforementioned embodiment. Regardless of whether the transmission order is determined, when the user's finger is on the sensing area SZ1-SZ4, the processor 120 can control the fingerprint sensing circuit 100 to capture the sensing information from the sensing area SZ1-SZ4. It should be noted that in some embodiments, the processor 120 can synchronously control the fingerprint sensing circuit 111-114 to capture the user's fingerprint (for example, at the same time).

[0110] Step S4: Control the fingerprint sensing circuit to transmit the sensing information corresponding to the sensing area via the shared transmission bus according to the transmission sequence.

[0111] In some embodiments, when the processor 120 determines the transmission sequence and controls the fingerprint sensing circuits 111 - 114 to retrieve sensing information from the sensing regions SZ1 - SZ4 , the processor 120 may control the fingerprint sensing circuits 111 - 114 to start transmitting the sensing information according to the transmission sequence.

[0112] In the aforementioned embodiment, assuming that the transmission order determined by the processor 120 is as shown in Table 1, the processor 120 can send instructions to each sensing circuit 111-114 for sensing information according to the transmission order. In this case, the processor 120 can send instructions to the fingerprint sensing circuits 111-114 in the following order. First, send instructions to the fourth fingerprint sensing circuit 114; then to the first fingerprint sensing circuit 111; then to the third fingerprint sensing circuit 113; and finally to the second fingerprint sensing circuit 112.

[0113] In the above embodiment, assuming that the transmission order determined by the processor 120 is as shown in Table 2, the processor 120 can send instructions to each fingerprint sensing circuit 111-114 for sensing information according to the transmission order. In this case, the processor 120 can send instructions to the fingerprint sensing circuits 111-114 in the following order. First, send instructions to the third fingerprint sensing circuit 113; then to the fourth fingerprint sensing circuit 114; third to the second fingerprint sensing circuit 112; and finally to the first fingerprint sensing circuit 111.

[0114] In the above embodiment, assuming that the transmission order determined by the processor 120 is as shown in Table 3, the processor 120 can send instructions to the fingerprint sensing circuits 111-114 for sensing information according to the transmission order. In this case, the processor can send instructions to the fingerprint sensing circuits 111-114 in the following order. First, the second fingerprint sensing circuit 112; then the first fingerprint sensing circuit 111; third, the third fingerprint sensing circuit 113; and finally, the fourth fingerprint sensing circuit 114.

[0115] In the above embodiment, assuming that the transmission order determined by the processor 120 is as shown in Table 4, the processor 120 can send instructions to each fingerprint sensing circuit 111-114 for interfering with information according to the transmission order. In this case, the processor 120 can send instructions to the fingerprint sensing circuits 111-114 in the following order: first, the first fingerprint sensing circuit 111; then the fourth fingerprint sensing circuit 114; third, the third fingerprint sensing circuit 113; and finally, the second fingerprint sensing circuit 112.

[0116] Step S5: receiving sensing information from the fingerprint sensing circuit according to the transmission order.

[0117] In some embodiments, because the fingerprint sensing circuits 111-114 are controlled to send sensing information according to the transmission order, the sensing information generated by the fingerprint sensing circuits 111-114 will be received by the processor 120 in the same transmission order. Therefore, the processor 120 can receive sensing information from the fingerprint sensing circuits 111-114 in the following order: the second fingerprint sensing circuit 112; the first fingerprint sensing circuit; the third fingerprint sensing circuit; and the fourth fingerprint sensing circuit.

[0118] Step S6: authenticating the fingerprint pattern in response to the received sensing information transmitted from the fingerprint sensing circuit.

[0119] In some embodiments, each time the processor 120 receives sensing information from a single fingerprint sensing circuit, the processor 120 may input the fingerprint sensing information to the fingerprint authentication application. As described above, generally, at least one of the fingerprint sensing circuits 111-114 may capture sufficient information from the sensing regions SZ1-SZ4 to authenticate the user's fingerprint.

[0120] Step S7: Assuming that the fingerprint pattern is successfully identified according to the received sensing information transmitted from one of the fingerprint sensing circuits, stop the other fingerprint sensing circuits from transmitting the sensing information.

[0121] In some embodiments, each time the sensing information from a single fingerprint sensing circuit is input to the fingerprint authentication application, the fingerprint authentication application may attempt to identify the user's fingerprint pattern based on the received sensing information. Once the fingerprint authentication application is executed by the processor 120, the processor 120 may transmit instructions to the remaining fingerprint sensing circuits 111-114 to stop the transmission based on the received sensing information from any one of the fingerprint sensing circuits 111-114.

[0122] More specifically, for example, in the case shown in Table 3 with the transmission order (SZ2, SZ1, SZ3, SZ4), assuming that the fingerprint authentication application has successfully identified the user's fingerprint pattern based on the fingerprint sensing information received from the first fingerprint sensing circuit 111, the processor 120 can transmit instructions to the fingerprint sensing circuits 113-114 to stop the transmission of their sensing information. That is, in the worst case, the processor 120 completes the fingerprint recognition after receiving all the sensing information from all the fingerprint sensing circuits 111-114. However, in the best case, when the processor 120 receives the sensing information from the second fingerprint sensing circuit 112, the fingerprint recognition has been successfully completed.

[0123] It should be noted that, assuming that the sensing information from the second fingerprint sensing circuit 112 triggers a successful fingerprint recognition, the processor 120 may increment the count corresponding to the second sensing zone SZ2 by one. In this manner, as the user continues to use the fingerprint detection device FD, the recognition success rate of each sensing zone can be optimized. According to this mechanism, the recognition success rate of the sensing zone can reflect the user's habits. Therefore, the efficiency of the fingerprint detection device 100 can be increased over time.

[0124] It can be understood that the method of the present invention can also be applied to different hardware configurations. For example, assuming that the fingerprint sensing module 110 is implemented by a single sensing circuit instead of the fingerprint sensing circuits 111-114, the processor 120 can also control the single sensing circuit to capture the sensing information and make the single sensing circuit transmit the sensing information corresponding to the sensing areas SZ1-SZ4 according to the arranged transmission order.

[0125] In the aforementioned embodiments, the fingerprint detection device 100 and the fingerprint detection device FD have multiple functional blocks or modules. As understood by those skilled in the art, in some embodiments, these functional blocks are preferably implemented by circuits (dedicated circuits or general circuits that operate under one or more processors and coding instructions) that typically include transistors or other circuit elements, and the transistors or other circuit elements are configured in such a manner to control the operation of the circuit according to the functions and operations described. It will be further understood that the specific structure or connection of the circuit elements is usually determined by a compiler, such as a Register Transfer Language (RTL) compiler. However, the scope of the present case is not limited to this.

[0126] Although the present invention has been disclosed as above in the form of an implementation method, it is not intended to limit the present invention. Anyone familiar with the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the attached claims.
