[0048] The present invention provides a touch device for use in electronic devices (such as laptops, tablets, or mobile phones). The touch device can implement both fingerprint recognition and touch control functions, and these two functions are performed by a single microprocessor, which helps reduce manufacturing costs.

[0049] In the embodiment of the present application, the electronic device is a laptop computer as an example to illustrate the structure of the electronic device. Figure 1 Electronic device 1 includes a display screen 300 and a touch device 100 electrically connected to display screen 300. Display screen 300 is used to display images. Touch device 100 is a touchpad on a laptop computer, which operates the image displayed on display screen 300 by sensing touch or fingerprint information from a finger or stylus. The following description uses the example of touch information coming from a finger, but the following also applies to touch information coming from a stylus.

[0050] See also Figure 2 The touch control device 100 of the embodiment of the present application includes a microprocessor 10 and a touch panel 20 electrically connected to each other. The touch panel 20 is used to collect touch or fingerprint information of a finger, and the microprocessor 10 is used to identify the touch position of the finger based on the touch information, or to identify the user's identity information based on the fingerprint information.

[0051] The microprocessor 10 has a signal transmission interface 101. In this embodiment, the signal transmission interface 101 is a Universal Serial Bus (USB) data interface. In other embodiments, the signal transmission interface 101 may be an Inter-Integrated Circuit (IIC) interface.

[0052] Please also refer to Figure 2 and Figure 3 The touch panel 20 includes a first area 21 and a second area 22 that are spliced ​​together. The first area 21 and the second area 22 are electrically connected to the microprocessor 10 at the same time. The microprocessor 10 is used to receive control signals through the signal transmission interface 101 and output them. The first area 21 is used to collect fingerprint information of the user's finger or touch information (including point touch, movement, etc.) of the finger on the touch panel 20 after receiving the control signal. The second area 22 is used to collect touch information of the user's finger after receiving the control signal. The first area 21 and the second area 22 are also used to send the collected fingerprint information and touch information to the microprocessor 10. In this embodiment, the first area 21 is used to collect fingerprint information and touch information in a time-sharing multiplexed manner, while the second area 22 is used to collect touch information.

[0053] See also Figure 3 In this embodiment, the first area 21 is a rectangular area, and the second area 22 surrounds and connects to the first area 21. The first area 21 and the second area 22 are combined to form the effective touch area 23 of the touch panel 20. In this embodiment, the effective touch area 23 is roughly rectangular, and the first area 21 is located at one corner of the effective touch area 23 ( Figure 3 In the illustrated orientation, the first area 21 is located in the upper right corner of the effective touch area 23. Since the fingerprint recognition area generally only needs to be larger than the area of ​​a single fingertip, and touch recognition requires space for finger taps and continuous sliding, the area of ​​the first area 21 in this embodiment is much smaller than that of the second area 22.

[0054] In this embodiment, after receiving different control signals via the signal transmission interface 101, the microprocessor 10 transmits the different control signals to the touch panel 20. The first area 21 of the touch panel 20 collects fingerprint information or touch information based on the different control signals. The control process of the microprocessor 10 and the operation of the first area 21 are described below.

[0055] When the microprocessor 10 outputs the first control signal, the first area 21 collects the fingerprint information of the finger according to the first control signal and transmits the fingerprint information back to the microprocessor 10. After receiving the fingerprint information, the microprocessor 10 identifies the user's identity information based on the fingerprint information.

[0056] When the microprocessor 10 outputs the second control signal, the first area 21 collects the touch information of the finger according to the second control signal and transmits the touch information back to the microprocessor 10. After receiving the touch information, the microprocessor 10 identifies the touch mode of the finger according to the touch information.

[0057] In this embodiment, the microprocessor 10 determines whether to output the first control signal or the second control signal based on the touch mode of the finger on the touch panel 20 .

[0058] See also Figure 4 When the touch panel 20 senses a finger touch, the microprocessor 10 is used to receive the finger touch information.

[0059] During the continuous movement of the finger on the touch panel 20, when the finger moves from the second area 22 to the first area 21 and moves to contact the first area 21 (the movement path of the finger is ① to ⑤), the microprocessor 10 is used to receive the second control signal through the signal transmission interface 101 and output it to the first area 21. After receiving the second control signal, the first area 21 collects the touch information of the finger.

[0060] See also Figure 5 When the first area 21 senses the touch of the finger and the second area 22 does not sense the touch of the finger, that is, the finger is located in the first area 21 and the finger never moves to the second area 22 (the finger's movement path is only ①, and ② to ⑤ do not appear), the microprocessor 10 is used to receive the first control signal through the signal transmission interface 101 and output it to the first area 21. After receiving the first control signal, the first area 21 collects the fingerprint information of the finger.

[0061] In this embodiment, the touch panel 20 includes a plurality of touch electrodes (not shown), some of which are located in a first region 21 and others in a second region 22. The microprocessor 10 is further configured to switch the resolution of the first region 21 by switching the connection between the touch electrodes in the first region 21.

[0062] See also Figure 6 When the first area 21 receives the first control signal, the touch electrodes in the first area 21 are connected in parallel and independently output the first capacitance value as fingerprint information to the microprocessor 10. At this time, the first area 21 has a first resolution.

[0063] See also Figure 7 When the first area 21 receives the second control signal, multiple touch electrodes arranged adjacent to each other in the first area 21 are connected in series and jointly output the second capacitance value to the microprocessor 10, or some touch electrodes in the first area 21 are selected to output the second capacitance value to the microprocessor 10, such as the odd-numbered touch electrodes respectively output the second capacitance value to the microprocessor 10. At this time, the first area 21 has the second resolution.

[0064] Figure 6 Each small grid in the first area 21 outputs a corresponding first capacitance value through the touch electrode. Figure 7Each small grid in the first area 21 includes a plurality of touch electrodes arranged adjacent to each other, and the plurality of touch electrodes arranged adjacent to each other are connected in series and jointly output a second capacitance value.

[0065] In summary, in the touch device 100 of the embodiment of the present application, the microprocessor 10 receives the first control signal or the second control signal through the signal transmission interface 101 and outputs it to the first area 21 and the second area 22. When the first area 21 receives the first control signal, the fingerprint recognition function is activated to collect fingerprint information of the finger. When the first area 21 receives the second control signal, the touch function is activated, and the second area 22 is used together to collect touch information of the finger, which helps to eliminate the user's operation blind spot when performing touch operations on the touch device 100. In addition, the present application combines the microprocessor for processing fingerprint information and the microprocessor for processing touch information into one microprocessor 10, and uses one signal transmission interface 101 to receive signals or output information, which helps to reduce production costs.

[0066] See also Figure 8 The present application also provides an electronic device 1, comprising a touch device 100 and a central processing unit (CPU) 200. The CPU 200 is electrically connected to a microprocessor 10 in the touch device 100 and is configured to output control signals to the microprocessor 10 via a signal transmission interface 101 based on the usage status of the electronic device 1. In this embodiment, the electronic device 1 is a laptop computer. In other embodiments, the electronic device 1 may be other terminal devices, such as a mobile phone, a smartwatch, etc.

[0067] See also Figure 9 , the electronic device 1 is in a fingerprint recording state or a biometric password login state, that is, when the user turns on the electronic device 1 or uses the electronic device 1 to log in to a personal account, the central processor 300 is used to output a first control signal to the microprocessor 10 through the signal transmission interface, and the microprocessor 10 transmits the first control signal to the first area 21. After receiving the first control signal, the first area 21 starts the fingerprint recognition function, and the microprocessor 10 recognizes the user's identity information after receiving the fingerprint information.

[0068] The electronic device 1 is in a state of reading or browsing page information, that is, when the user is watching the content displayed by the electronic device 1 or needs to operate the display screen on the electronic device 1, the central processing unit 200 is used to output a first control signal to the microprocessor 10 through the signal transmission interface, and the microprocessor 10 transmits the second control signal to the first area 21 and the second area 22. After the first area 21 and the second area 22 receive the second control signal, the touch function is started at the same time. After receiving the touch information, the microprocessor 10 identifies the touch mode of the finger.

[0069] The central processing unit 200 identifies the usage scenario or usage status of the electronic device 1 and outputs a first control signal or a second control signal to the microprocessor 10 through the signal transmission structure 101. The microprocessor 10 transmits the first control signal or the second control signal to the first area 21, so that the first area 21 can collect both fingerprint information and touch information of the finger. That is, the first area 21 has both fingerprint recognition function and touch function, which is conducive to eliminating the operation blind spot on the touch device 100 of the electronic device 1 and improving the user experience.
