Detailed Description
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it should be understood that these practical details are not to be taken as limiting the invention. That is, in some embodiments of the invention, these practical details are unnecessary. Moreover, for the purpose of simplifying the drawings, some conventional structures and elements are shown in the drawings in a simplified schematic manner.
Please refer to fig. 1 and 2. Fig. 1 is a functional block diagram of an electronic device 100 and a fingerprint recognition module 110 according to an embodiment of the invention. Fig. 2 is a schematic front view of an electronic device 100 according to an embodiment of the invention. The electronic device 100 includes a fingerprint identification module 110 and a display 130. The fingerprint recognition module 110 includes a fingerprint recognition element 111, an even number of touch sensing elements 113 and a processor 115 (the processor 115 is disposed inside the electronic device 100 and is omitted in fig. 2). The fingerprint recognition element 111 is configured to sense a biological feature of the skin surface of the finger and output a recognition signal. An even number of touch sensing elements 113 surround the fingerprint identification element 111, and the touch sensing elements 113 respectively output sensing signals after touching. The even number of touch sensing elements 113 may be disposed at intervals and surround the fingerprint sensing element 111, so that the touch sensing elements 113 and the fingerprint sensing element 111 have insulation gaps therebetween. The processor 115 is coupled to the fingerprint identification element 111 and the even number of touch sensing elements 113, and the processor 115 is configured to output a first control signal to the fingerprint identification element 111 to control the fingerprint identification element 111 to be turned on or turned off according to the sequence or the number of the sensing signals after receiving the sensing signals. The processor 115 is further configured to output a second control signal to the touch sensing element 113 according to the identification signal to control the touch sensing element 113 to be turned on or turned off. The fingerprint recognition element 111 may include a fingerprint recognition integrated circuit (Integrated Circuit), and the fingerprint recognition element 111 may be circular, rectangular or elliptical, which is not limited to the present invention. The touch sensing element 113 may include a touch sensing integrated circuit, and the touch sensing element 113 may be adjusted according to the shape of the fingerprint sensing element 111 to surround the fingerprint sensing element 111, for example, when the fingerprint sensing element 111 is circular and the touch sensing element 113, the touch sensing element 113 may be in a semi-circular shape or a quarter-circular shape. The processor 115 may be a microprocessor (Microcontroller Unit) and disposed inside the electronic device 100.
Specifically, the fingerprint identification element 111 identifies the fingerprint biometric of the finger, and further identifies the identity of the user. The touch sensing device 113 is normally set to a scan state, and the fingerprint sensing device 111 is in a closed state with a ground potential. When the touch sensing device 113 outputs the sensing signal after touching, the processor 115 sends the first control signal to the fingerprint identification device 111 to turn on the fingerprint identification device 111 after receiving the sensing signal. After the touch sensing element 113 is touched, the fingerprint identification element 111 is turned on to identify the biological characteristics of the finger of the user. That is, by arranging the fingerprint recognition element 111, the touch sensing element 113 and the processor 115, the touch sensing element 113 surrounds the fingerprint recognition element 111, so that the fingerprint recognition element 111 can be turned on only when the fingerprint recognition element 111 is close to a human body, and the power saving function of the fingerprint recognition module 110 can be achieved.
In various embodiments of the present invention, the processor 115 of the fingerprint identification module 110 receives more than half of the sensing signals of the touch sensing elements 113, and outputs the first control signal to turn on the fingerprint identification element 111. Specifically, the touch sensing elements 113 may be two, four, six or more even numbers, but the invention is not limited thereto. After more than half of the touch sensing elements 113 respectively send sensing signals to the processor 115 due to touch, the fingerprint identification element 111 can be turned on, so that the situation that the power waste is caused by the fact that the fingerprint identification element 111 is turned on due to the fact that the touch sensing elements 113 are touched by mistake can be reduced.
Please refer to fig. 1. In various embodiments of the invention. When the fingerprint identification device 111 is turned on, the fingerprint identification device 111 first senses whether there is a fingerprint biometric of the finger. When the fingerprint identification element 111 does not sense the fingerprint biometric feature, the fingerprint identification element 111 sends out an identification signal about the biometric feature of the finger which is not sensed, and the processor 115 outputs a second control signal to the fingerprint identification element 111 and turns off the fingerprint identification element 111 after receiving the identification signal about the biometric feature of the finger which is not sensed. In short, the processor 115 receives the identification signal about the fingerprint biological characteristics of the finger which is not sensed, and outputs the second control signal to the fingerprint identification device 111 to turn off the fingerprint identification device 111, so as to avoid wasting power for achieving the energy saving effect due to the continuous operation of the fingerprint identification device 111. In addition, when the fingerprint identification element 111 senses the fingerprint biological feature of the finger, the identity authentication is further performed by the fingerprint biological feature of the finger, and the user identity authentication procedure is completed.
In addition, when the processor 115 of the fingerprint recognition module 110 receives the recognition signal about the biological feature of the finger, it further outputs a first control signal to the touch sensing element 113 to turn on the touch sensing element 113. Specifically, after the fingerprint identification element 111 is turned on, if the fingerprint biological feature of the finger is not sensed, the processor 115 sends a signal to the fingerprint identification element 111 and turns off the fingerprint identification element 111 to save energy, at this time, the processor 115 can send a signal to the touch sensing element 113 and turn on the touch sensing element 113 at the same time, so that the touch sensing element 113 is restored to the scanning state, that is, the fingerprint identification module 110 is restored to the state before the touch sensing element 113 is triggered, and whether the fingerprint identification element 111 is close to or touched by a human body is continuously detected.
In short, due to the configuration and the setting of the fingerprint identification element 111, the touch sensing element 113 and the processor 115, the fingerprint identification module 110 can achieve the condition that the fingerprint identification element 111 and the touch sensing element 113 are respectively turned on or off, so that the fingerprint identification element 111 and the touch sensing element 113 only operate when necessary and avoid simultaneous operation, thereby not only achieving the energy saving effect, but also avoiding the signal interference caused by the fact that the fingerprint identification element 111 and the touch sensing element 113 are simultaneously turned on.
Please refer to fig. 1 and 2. In other embodiments, the electronic device 100 includes a fingerprint recognition module 110 and a display 130. The fingerprint recognition module 110 includes a fingerprint recognition element 111, an even number of touch sensing elements 113, and a processor 115. The fingerprint recognition element 111 is configured to sense a biological feature of the finger and output a recognition signal. The even number of touch sensing elements 113 encircle the fingerprint identification element 111, and the touch sensing elements 113 respectively output a sensing signal after touching. The processor 115 is coupled to the fingerprint identification element 111, the touch sensing element 113 and the display 130. The processor 115 is configured to output a first control signal to the fingerprint identification device 111 according to the sequence or the number of the sensing signals after receiving the sensing signals, so as to control the fingerprint identification device 111 to be turned on or turned off. The processor 115 is further configured to receive the identification signal generated by the fingerprint identification element 111, and output a second control signal to the touch sensing element 113 according to the identification signal to control the touch sensing element 113 to be turned on or turned off. In addition, after receiving the sensing signals, the processor 115 may output a third control signal to the display 130 according to the sequence or the number of the sensing signals to control the display 130 to display a display frame change.
The processor 115 in this embodiment further controls the display 130 to generate different display effects based on the received sensing signals sent by the touch sensing element 113. That is, when the user touches the touch sensing device 113 according to different sequences or modes, the display 130 controls the display screen changing effect of the display 130 according to the sensing signals generated by the sequence and the number of the touch sensing devices 113 touched, and the display screen changing effect of the display 130 and the sequence and the number of the touch sensing devices 113 touched are not described in detail herein.
In some embodiments of the present invention, when one of the even number of touch sensing elements 113 outputs a sensing signal after touching, the processor 115 receives and outputs a third control signal to the display 130 according to the sensing signal, so as to generate a click effect on the display screen of the display 130. The clicking effect of the display screen in the invention is to simulate the clicking effect of the touch screen by the user, for example, simulate clicking the touch screen of a smart phone to achieve the function of opening the application program, and the invention is not limited thereto. In addition, the processor 115 may also be configured to receive and output the third control signal to the display 130 according to the sensing signals sent by the two touch sensing elements 113 at the same time, so that the display screen of the display 130 has a click effect, that is, the user needs to touch the two touch sensing elements 113 at the same time and then send the sensing signals at the same time. The user can also adjust the three or four according to the actual requirement, and the invention is not limited to this.
In some embodiments of the present invention, when one of the even number of touch sensing elements 113 outputs a sensing signal after the touch is continued for more than three seconds, the processor 115 receives and outputs a third control signal to the display 130 according to the sensing signal, so that the display screen of the display 130 is pressed. The pressing effect of the display screen according to the present invention is to simulate the effect of continuously pressing the touch screen by the user, such as continuously pressing the touch screen of a smart phone, but the present invention is not limited thereto. In addition, it may be configured that the processor 115 receives and outputs the third control signal to the display 130 according to the sensing signal sent by the touch sensing element 113 after continuously touching both the even number of touch sensing elements 113 for more than three seconds, so as to generate a pressing effect on the display screen of the display 130. The touch control device may be adjusted to simultaneously touch three or four touch sensing elements 113 according to actual requirements, which is not limited by the present invention. In addition, in the present embodiment, the number of seconds of the continuous touch may be five seconds or other seconds, and may be adjusted based on the requirement, which is not limited to the present invention.
Referring to fig. 2, in some embodiments of the present invention, the number of the touch sensing elements 113 is two, and the touch sensing elements 113 sequentially output sensing signals after sequentially touching, and the processor 115 receives and outputs a third control signal to the display 130 according to the sensing signals, so that the display screen of the display 130 generates a sliding effect. Specifically, the touch sensing element 113 surrounds the fingerprint identification element 111 and may be disposed on two sides of the fingerprint identification element 111. When the two touch sensing elements 113 are sequentially touched, the display screen of the display 130 slides in a specific direction due to a sliding effect, and the sliding direction may be the same as or opposite to the direction of sequentially touching the touch sensing elements 113. However, the present invention is not limited thereto, and the user can adjust the display screen to slide in any direction according to the requirement. The sliding effect of the display screen according to the present invention is that the display screen moves in one direction relative to the display 130.
In addition, the touch sensing device 113 may be configured to sequentially output the sensing signal to the processor 115 within one second, and then the processor 115 outputs the third control signal to the display 130 to generate the sliding effect on the display screen. That is, when the user touches the touch sensing device 113 sequentially within one second, the touch sensing device 113 sequentially outputs the sensing signal to the processor 115 within one second, so as to prevent the display screen from sliding due to the error touch caused by the excessively long instruction receiving time. However, the present invention is not limited thereto, and the user can adjust the number of seconds according to the distance between the touch sensing elements 113 or the requirement, and can adjust the number of seconds to three seconds, five seconds or other seconds when the distance between the touch sensing elements 113 is longer.
Referring to fig. 3, in other embodiments of the present invention, the fingerprint recognition module 110A of the electronic device 100A includes four touch sensing elements 113A. Four touch sensing elements 113A surround the fingerprint recognition element 111. When three of the four touch sensing elements 113A sequentially output sensing signals after sequentially touching, the processor 115 receives and outputs a third control signal to the display 130 according to the sensing signals, so that the display screen of the display 130 generates a rotation effect. The rotation effect referred to in the present invention is an effect that the display screen rotates with respect to the display 130 based on one point. The order of sequentially touching the touch sensing elements 113A may be in the direction facing the touch sensing elements 113A, and sequentially touching in the clockwise direction or the counter-clockwise direction, which is not a limitation of the present invention. In addition, the display screen of the display 130 can generate a rotation effect according to the direction of the touch sequence, and the display screen can rotate in the same direction or in the opposite direction to the direction of the touch sequence, which is not limited by the invention.
In addition, the touch sensing device 113A may be configured to sequentially output the sensing signal to the processor 115 within one second, and then the processor 115 outputs the third control signal to the display 130 to generate the rotation effect on the display screen. That is, the user needs to touch the touch sensing device 113A sequentially within one second, and the touch sensing device 113A can sequentially output the sensing signal to the processor 115 within one second, so as to avoid the display screen from generating a rotation effect due to the error touch caused by the overlong instruction receiving time. However, the present invention is not limited thereto, and the user can adjust the number of seconds according to the distance between the touch sensing elements 113A or the requirement, and can adjust the number of seconds to three seconds, five seconds or other seconds when the distance between the touch sensing elements 113A is far.
Referring to fig. 3 again, in another embodiment of the present invention, when two of the four touch sensing elements 113A sequentially output sensing signals after sequentially touching, the processor 115 receives and outputs a third control signal to the display 130 according to the sensing signals, so that the display screen of the display 130 generates a sliding effect. Specifically, two of the four touch sensing elements 113A that are sequentially touched may be two adjacent ones, or two of the four touch sensing elements that are located at two sides of the fingerprint identification element 111, which is not limited by the present invention. The remaining details are substantially the same as those described above, and the present invention is not repeated here.
Referring to fig. 4 and 5, in other embodiments of the invention, the fingerprint recognition module 110B of the electronic device 100B includes six touch sensing elements 113B. Six touch sensing elements 113B surround the fingerprint recognition element 111. The hand H sequentially touches adjacent three of the six touch sensing elements 113B based on the direction R and then sequentially outputs the sensing signals, and the processor 115 receives and outputs the third control signal to the display 130 according to the sensing signals, so that the display screen of the display 130 generates a rotation effect. The direction R may be a clockwise direction or an anticlockwise direction facing the touch sensing element 113B, which is not limited by the present invention. The display screen of the display 130 is rotated in the direction R.
In addition, the touch sensing device 113B may be configured to sequentially output the sensing signal to the processor 115 within one second, and then the processor 115 outputs the third control signal to the display 130 to generate the rotation effect on the display screen. That is, the user needs to touch the adjacent three touch sensing elements 113B sequentially within one second, and the touch sensing elements 113B can sequentially output the sensing signals to the processor 115 within one second, so as to avoid the display screen from generating a rotation effect due to the error touch caused by the overlong receiving instruction time. However, the present invention is not limited thereto, and the user can adjust the number of seconds according to the distance between the touch sensing elements 113B or the requirement, and can adjust the number of seconds to three seconds, five seconds or other seconds when the distance between the touch sensing elements 113B is far.
Referring to fig. 4 and fig. 6 again, in another embodiment of the present invention, two of the six touch sensing elements 113B are sequentially touched by the hand H based on the direction S, and the processor 115 receives and outputs a third control signal to the display 130 according to the sensing signal, so that the display screen of the display 130 generates a sliding effect. Specifically, two of the six touch sensing elements 113B may be adjacent to each other, or may be located at two sides of the fingerprint sensing element 111, and the direction S may be defined based on the relative positions of the touch sensing elements 113B, that is, the direction S is determined by the direction and the sequence of sequentially touching the touch sensing elements 113B by the hand H, for example, in fig. 6, the direction S is directed to the left side, which is the right-to-left direction, but the invention is not limited thereto. The display screen of the display 130 generates a sliding effect according to the touch direction S, and the display screen can generate a sliding effect in the same direction or opposite direction to the direction S.
Taking the touch sensing elements 113B on both sides of the fingerprint identification element 111 as an example, it may be set that the touch sensing elements 113B finish sequentially outputting the sensing signals to the processor 115 within five seconds, and the processor 115 outputs the third control signal to the display 130 to generate the sliding effect on the display screen. The other details are substantially the same as those described above, and will not be described here again.
In summary, by the above configuration and the above configuration relationship, the electronic device and the fingerprint identification module provided by the present invention can achieve the effect of saving energy and avoiding signal interference by enabling the fingerprint sensing element and the touch sensing element to be turned on when necessary by the configuration relationship of the fingerprint sensing element, the touch sensing element and the processor. In addition, by means of the setting and configuration relation of the touch sensing element, the processor and the display, the fingerprint identification module provided by the invention has more functions, and can even replace a touch panel under certain conditions so as to achieve the function of controlling the change of a display picture.
From the foregoing detailed description of the embodiments of the invention, it will be obvious that, although the present invention has been described in terms of embodiments, it is not intended to be limited thereto, but rather to various modifications and adaptations may be made by those skilled in the art without departing from the spirit and scope of the present invention, the scope of which is defined in the following claims.
