Detailed Description
In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the present invention. It should be understood, however, that these implementation details are not to be interpreted as limiting the invention. That is, in some embodiments of the invention, such implementation details are not necessary. In addition, for the sake of simplicity, some conventional structures and elements are shown in the drawings.
Please refer to fig. 1 and fig. 2. FIG. 1 is a block diagram of an electronic device 100 and a fingerprint recognition module 110 thereof according to an embodiment of the invention. Fig. 2 is a schematic front view illustrating an electronic device 100 according to an embodiment of the invention. The electronic device 100 includes a fingerprint recognition module 110 and a display 130. The fingerprint identification module 110 includes a fingerprint identification device 111, an even number of touch sensing devices 113, and a processor 115 (the processor 115 is disposed inside the electronic device 100 and is omitted in fig. 2). The fingerprint recognition device 111 is configured to sense a biometric characteristic of the skin surface of the finger and output a recognition signal. The even number of touch sensing devices 113 surround the fingerprint identification device 111, and the touch sensing devices 113 respectively output sensing signals after being touched. The even number of touch sensing elements 113 may be disposed at intervals and surround the fingerprint identification element 111, so that an insulation gap is formed between the touch sensing elements 113 and the fingerprint identification element 111. The processor 115 is coupled to the fingerprint identification device 111 and the even number of touch sensing devices 113, and the processor 115 is configured to receive the sensing signals and output first control signals to the fingerprint identification device 111 according to the sequence or number of the sensing signals to control the fingerprint identification device 111 to be turned on or turned off. The processor 115 is further configured to output a second control signal to the touch sensing device 113 according to the identification signal to control the touch sensing device 113 to turn on or off. The fingerprint sensor 111 may include an Integrated Circuit (Integrated Circuit), and the fingerprint sensor 111 may be circular, rectangular or oval, but the invention is not limited thereto. The touch sensing device 113 may include a touch sensing integrated circuit, and the touch sensing device 113 may be adjusted to surround the fingerprint identification device 111 according to the shape of the fingerprint identification device 111, for example, when the fingerprint identification device 111 is circular and the touch sensing device 113 is touch sensing device 113, the touch sensing device 113 may be a half-circle ring or a quarter-circle ring. The processor 115 may be a microprocessor (Microcontroller Unit) and is disposed within the electronic device 100.
Specifically, the fingerprint identification device 111 identifies the fingerprint biometric feature of the finger, and further identifies the identity of the user. The touch sensing device 113 is normally set to a scanning state, and the fingerprint identification device 111 is in a turn-off state of ground potential. When the touch sensing device 113 is touched, the touch sensing device outputs a sensing signal, and the processor 115 receives the sensing signal and then sends a first control signal to the fingerprint identification device 111 to turn on the fingerprint identification device 111. After the touch sensing device 113 is touched, the fingerprint identification device 111 is turned on to identify the biometric characteristic of the finger of the user. That is, by the arrangement of the fingerprint identification device 111, the touch sensing device 113 and the processor 115, the touch sensing device 113 surrounds the fingerprint identification device 111, and can be turned on only when the fingerprint identification device 111 is approached by a human body, so that the fingerprint identification device 111 is turned on when necessary, and the power saving function of the fingerprint identification module 110 is achieved.
In various embodiments of the present invention, the processor 115 of the fingerprint identification module 110 receives more than half of the number of the touch sensing devices 113, and outputs the first control signal to turn on the fingerprint identification device 111. Specifically, the number of the touch sensing elements 113 may be two, four, six or more, and is an even number, but the invention is not limited thereto. When more than half of the touch sensing devices 113 respectively send sensing signals to the processor 115 due to touch, the fingerprint identification device 111 can be turned on, thereby reducing the power waste caused by the false touch of the touch sensing devices 113 to turn on the fingerprint identification device 111.
Please refer to fig. 1. In various embodiments of the present invention. When the fingerprint identification device 111 is turned on, the fingerprint identification device 111 first senses whether there is a fingerprint biometric feature of a finger. When the fingerprint identification device 111 cannot sense the fingerprint biometric feature, the fingerprint identification device 111 will send out an identification signal related to the biometric feature of the finger, and the processor 115 outputs a second control signal to the fingerprint identification device 111 and turns off the fingerprint identification device 111 after receiving the identification signal related to the biometric feature of the finger. In short, the processor 115 receives the identification signal related to the fingerprint biometric characteristic of the finger, and outputs the second control signal to the fingerprint identification device 111 to turn off the fingerprint identification device 111, so as to prevent the fingerprint identification device 111 from continuously operating and wasting power to achieve the energy saving effect. In addition, after the fingerprint identification device 111 senses the fingerprint biometric characteristic of the finger, the identification is further performed by the fingerprint biometric characteristic of the finger, and the procedure of the user identification is completed.
In addition, when the processor 115 of the fingerprint identification module 110 receives the identification signal related to the non-sensing biometric characteristic of the finger, the processor further outputs a first control signal to the touch sensing device 113 to turn on the touch sensing device 113. Specifically, after the fingerprint identification device 111 is turned on, if the fingerprint biometric characteristic of the finger is not sensed, the processor 115 may send a signal to the fingerprint identification device 111 and turn off the fingerprint identification device 111 to save energy, at this time, the processor 115 may send a signal to the touch sensing device 113 and turn on the touch sensing device 113 at the same time, so as to restore the touch sensing device 113 to a scanning state, that is, the fingerprint identification module 110 is restored to a state before the touch sensing device 113 is triggered, and continuously detect whether the fingerprint identification device 111 is approached or touched by a human body.
In short, due to the configuration relationship and setting of the fingerprint identification device 111, the touch sensing device 113 and the processor 115, the fingerprint identification module 110 can achieve the state that the fingerprint identification device 111 and the touch sensing device 113 are respectively turned on or turned off, so that the fingerprint identification device 111 and the touch sensing device 113 are respectively operated only when necessary and are prevented from being operated simultaneously, and not only can the energy-saving effect be achieved, but also the mutual interference of signals caused by the fact that the fingerprint identification device 111 and the touch sensing device 113 are simultaneously turned on can be avoided.
Please refer to fig. 1 and fig. 2. In other embodiments of the present invention, the electronic device 100 includes a fingerprint recognition module 110 and a display 130. The fingerprint identification module 110 includes a fingerprint identification device 111, an even number of touch sensing devices 113, and a processor 115. The fingerprint recognition device 111 is configured to sense a biometric characteristic of a finger and output a recognition signal. The even number of touch sensing devices 113 surround the fingerprint identification device 111, and the touch sensing devices 113 respectively output a sensing signal after being touched. The processor 115 is coupled to the fingerprint recognition device 111, the touch sensing device 113 and the display 130. The processor 115 is configured to receive the sensing signals and output a first control signal to the fingerprint identification device 111 according to the sequence or number of the sensing signals to control the fingerprint identification device 111 to be turned on or off. The processor 115 is further configured to receive the identification signal generated by the fingerprint identification device 111 and output a second control signal to the touch sensing device 113 according to the identification signal to control the touch sensing device 113 to turn on or off. In addition, after receiving the sensing signals, the processor 115 may also output a third control signal to the display 130 according to the sequence or number of the sensing signals to control the display frame of the display 130 to change.
The processor 115 in this embodiment further controls the display 130 to generate different display frame effects based on the sensing signals sent by the received touch sensing device 113. That is, when the user touches the touch sensing device 113 according to different sequences or manners, the display 130 controls the display variation effect of the display 130 according to the sensing signals generated by the sequence and number of touched touch sensing devices 113, and the display variation effect of the display 130 and the sequence and number of touched touch sensing devices 113 are described in detail later, which will not be described herein.
In some embodiments of the present invention, when one of the even number of touch sensing elements 113 outputs a sensing signal after being touched, the processor 115 receives the sensing signal 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 click effect. The click effect of the display screen referred in the present invention is an effect of simulating the click of the touch screen by the user, for example, simulating the click of the touch screen of the smart phone to achieve the function of starting the application program, which is not limited by the present invention. In addition, the processor 115 may be configured to receive and output a third control signal to the display 130 according to the sensing signals simultaneously sent by the two touch sensing devices 113, so that the display screen of the display 130 generates a click effect, that is, the user needs to simultaneously touch the two touch sensing devices 113 and then send out the sensing signals simultaneously. The user can adjust the number of the user to three or four according to the actual requirement, but the invention is not limited thereto.
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 continues for more than three seconds, the processor 115 receives the sensing signal 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 pressing effect. The pressing effect of the display screen according to the present invention is an effect of simulating the touch screen being continuously pressed by the user, such as simulating the touch screen of a smart phone being continuously pressed, but the present invention is not limited thereto. In addition, it can also be set that the processor 115 receives the sensing signal sent by the even number of touch sensing elements 113 and outputs the third control signal to the display 130 according to the sensing signal sent by the touch sensing element 113, so that the display screen of the display 130 generates the pressing effect. The touch sensing device can also be adjusted to continuously touch three or four touch sensing elements 113 at the same time according to actual requirements, which is not limited by the invention. In addition, in the embodiment of the invention, the number of seconds of the continuous touch may be five seconds or other numbers of seconds, which can be adjusted based on the requirement, and the invention is not limited thereto.
Referring to fig. 2, in some embodiments of the present invention, there are two touch sensing devices 113, and the touch sensing devices 113 sequentially output sensing signals after being sequentially touched, and the processor 115 receives the sensing signals 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 device 113 surrounds the fingerprint identification device 111 and can be disposed on two corresponding sides of the fingerprint identification device 111. When the two touch sensing devices 113 are sequentially touched, the display screen of the display 130 slides in a specific direction by a sliding effect, and the sliding direction may be the same as or opposite to the direction of sequentially touching the touch sensing devices 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 a direction relative to the display 130.
In addition, it can be configured that after the touch sensing device 113 sequentially outputs the sensing signals to the processor 115 within one second, the processor 115 outputs a third control signal to the display 130 to generate a sliding effect on the display screen. That is, when the user sequentially touches the touch sensing device 113 within one second, the touch sensing device 113 sequentially outputs sensing signals to the processor 115 within one second, thereby preventing the display screen from sliding due to erroneous touch caused by too 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 touch sensing elements 113 are far away.
Referring to fig. 3, in another embodiment of the present invention, the fingerprint identification module 110A of the electronic device 100A includes four touch sensing elements 113A. The 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 being sequentially touched, the processor 115 receives the sensing signals 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 according to the present invention is an effect that the display screen rotates with respect to the display 130 based on one point. The touch sensing device 113A can be touched sequentially in a clockwise direction or a counterclockwise direction in a direction facing the touch sensing device 113A, which is not limited in 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 output the sensing signals to the processor 115 sequentially within one second, and then the processor 115 outputs the third control signal to the display 130 to generate the rotation effect of the display screen. That is, the user needs to sequentially touch the touch sensing device 113A within one second, and the touch sensing device 113A can sequentially output the sensing signals to the processor 115 within one second, thereby avoiding the rotation effect of the display screen caused by the erroneous touch due to the 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 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 devices 113A sequentially output sensing signals after being sequentially touched, the processor 115 receives the sensing signals 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 touched sequentially may be two adjacent touch sensing elements, or two touch sensing elements located at two sides of the fingerprint identification element 111, which is not limited in the present invention. The remaining details are substantially the same as those described above, and the present invention is not described herein again.
Referring to fig. 4 and 5, in another embodiment of the invention, the fingerprint identification module 110B of the electronic device 100B includes six touch sensing elements 113B. The six touch sensing elements 113B surround the fingerprint recognition element 111. The processor 115 receives the sensing signals 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 direction R may be clockwise or counterclockwise facing the touch sensing device 113B, but the invention is not limited thereto. The display screen of the display 130 generates a rotation effect in the direction R.
In addition, the touch sensing device 113B may be configured to output the sensing signals to the processor 115 sequentially within one second, and then the processor 115 outputs the third control signal to the display 130 to generate the rotation effect of the display screen. That is, the user needs to sequentially touch the three adjacent touch sensing elements 113B within one second, and the touch sensing elements 113B can sequentially output the sensing signals to the processor 115 within one second, thereby avoiding the display screen from rotating due to mistaken touch caused by too 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 113B or the requirement, and can adjust the number of seconds to three seconds, five seconds or other seconds when the touch sensing elements 113B are far away.
Referring to fig. 4 and 6, in another embodiment of the present invention, two of the six touch sensing elements 113B are sequentially touched by a 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 sequentially touched may be adjacent two, or two of the six touch sensing elements located at two sides of the fingerprint identification 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 sequence of the touch sensing elements 113B sequentially touched by the hand H, for example, the touch sensing elements 113B are sequentially touched from right to left in fig. 6, and the direction S faces to the left, which is not limited in the present invention. 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 the opposite direction to the direction S, which is not limited by the invention.
Taking the touch sensing devices 113B on both sides of the fingerprint identification device 111 as an example, the touch sensing devices 113B can be set to output the sensing signals to the processor 115 sequentially 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 remaining details are substantially the same as those described above, and are not described herein again.
In summary, with the above setting and configuration relationship, the electronic device and the fingerprint identification module provided by the invention can achieve the effect that the fingerprint sensing element and the touch sensing element are turned on when necessary by the configuration relationship among the fingerprint sensing element, the touch sensing element and the processor, thereby achieving the effects of saving energy and avoiding signal interference. In addition, by setting and configuring the touch sensing element, the processor and the display, the fingerprint identification module provided by the invention has more functionality, and can even replace a touch panel under certain conditions so as to achieve the function of controlling the change of a display picture.
