Description

Working method of touch device and terminal

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method for operating a touch device and a terminal.

Background

With the continuous development of communication technology, the terminal has various touch modules, and can provide a human-computer interaction function. Also, as the terminal layout becomes more compact and the chip size is further reduced, electromagnetic Interference (EMI) between the mold assemblies becomes more prominent.

For example: the module contained in the terminal generally has a Touch screen (TP) capable of detecting a Touch position, a fingerprint identifier capable of identifying fingerprint lines, and the like. The touch screen can adopt a capacitance type or pressure type identification technology, and the fingerprint identifier can adopt identification technologies such as optical imaging, ultrasonic reflection, semiconductor capacitance change and the like. Generally, the working frequency point of the touch screen is a certain frequency between 100kHz and 400kHz, and the working frequency point of the fingerprint recognizer is a certain frequency between 200 kHz and 350 kHz. When the operating frequencies of the two module assemblies are close to each other, the module assemblies have frequency tolerance problems in mass production, and the actual operating frequencies of the module assemblies fluctuate with the change of temperature. Therefore, the actual working frequency points of the two module assemblies are probably overlapped, so that when a user operates the two module assemblies simultaneously, the mutual interference condition exists, the problems of no response to touch, dialing linkage, screen jumbling, failure in fingerprint unlocking and the like can occur, and the use experience is seriously influenced.

Disclosure of Invention

According to the working method of the touch device and the terminal, the interference between different module assemblies in the terminal can be reduced, and the use experience of the terminal is improved.

In a first aspect, an embodiment of the present application provides a method for operating a touch device, where the method is applied to a terminal including a fingerprint identifier and a touch screen, where the touch screen includes a touch sensor and a display screen, and the method includes:

the fingerprint recognizer detects touch operation of a user; the fingerprint recognizer determines the working mode of the fingerprint recognizer according to the touch operation of a user; if the working mode of the fingerprint identifier is a preset working mode, the touch screen starts a working mode of frequency hopping or working signal intensity improvement; and if the touch screen detects that the interference signal meets the preset condition, a touch sensor in the touch screen hops frequency or improves the working signal intensity.

Therefore, in the scheme provided by the embodiment of the application, when the fingerprint identifier is determined to be in the preset working mode, the touch screen starts the working mode of frequency hopping or working signal strength improvement. Then, after the detected interference signal is determined to meet the preset condition, the touch sensor of the touch screen hops frequency or improves the working signal intensity, and then the interference between the fingerprint identifier and the touch screen is reduced.

In one possible implementation, the preset operation mode includes: the fingerprint recognizer is in a legal unlocking working mode, or the fingerprint recognizer is in a working mode in a terminal unlocking state; the fingerprint recognizer is in a legal unlocking working mode, namely the fingerprint of a user is collected by the fingerprint recognizer when the terminal is in a screen locking state, the fingerprint of the user is successfully verified, and the fingerprint recognizer informs the terminal of the unlocking working mode; the working mode that the fingerprint identifier is in the terminal unlocking state refers to a working mode that the fingerprint identifier detects clicking, double-clicking, long-pressing or sliding operation of a user when the terminal is in the unlocking state.

It should be noted that, when the fingerprint identifier is in the legal unlocking operating mode or in the operating mode in the terminal unlocking state, it may be considered that both the fingerprint identifier and the touch screen are in the operating state, and at this time, if the user notifies that both the fingerprint identifier and the touch screen are touched, mutual interference between the two modules may be caused. Therefore, the touch screen is required to start a working mode for frequency hopping or improving the working signal strength so as to reduce mutual interference between the two module assemblies and avoid the abnormality of the terminal.

Furthermore, in the embodiment of the present application, when either one or both of the touch screen and the fingerprint identifier are in a non-operating state (including a sleep state, an off state, etc.), the terminal may not turn on (or turn off) the operating mode of frequency hopping or increasing the operating signal strength. For example: when the fingerprint recognizer is in a dormant state, the fingerprint recognizer can be considered to be in a non-working state, and at the moment, the touch screen does not start (or close) a working mode of frequency hopping or improving the working signal intensity. Another example is: the touch screen is in a screen-off state or a screen-locking state, and the touch screen can be considered to be in a non-working state, and at the moment, the touch screen can not start (or close) a working mode of frequency hopping or improving the working signal intensity. Therefore, the time for the touch screen to start the frequency hopping or improve the working mode of the working signal strength is reduced, the time for the touch screen to periodically inquire the result of the interference signal and judge whether the interference signal meets the preset condition is reduced, the power consumption of the terminal is saved, and the response speed of the touch screen is improved.

In a possible implementation manner, the preset condition is that the frequency of the interference signal is the sensitive frequency of a touch sensor in the touch screen, and the intensity of the interference signal reaches a threshold value; the sensitivity frequency of the touch sensor is m times to n times of the fundamental frequency or odd harmonic of the working signal of the touch sensor, wherein m is more than 0 and less than 1, and n is more than 1 and less than 2.

It should be noted that the abnormal operation of the touch screen caused by the interference signal needs to satisfy a preset condition. The preset conditions include that the frequency of the interference signal is within a sensitive frequency range of the operating frequency of the touch screen (that is, the frequency of the interference signal is close to the operating frequency of the touch screen), and the intensity of the interference signal reaches a certain threshold. This is because the interference signal is located in the sensitive range of the operating frequency of the touch screen, and the interference signal affects the operation of the touch screen. The intensity of the interference signal reaches a certain threshold value, which can cause the abnormal operation of the touch screen.

The sensitive frequency interval of the touch screen is an interval near the fundamental frequency or odd harmonic of the touch screen working signal, and may be, for example, 0.9 to 1.1 times of the touch screen working frequency.

In a possible implementation manner, if the working mode of the fingerprint identifier is the preset working mode, the touch screen starts the working mode of frequency hopping or improving the working signal strength, specifically:

if the fingerprint identifier determines that the working mode of the fingerprint identifier is the preset working mode, the fingerprint identifier sends first information to the touch screen, and the first information is used for informing the touch screen of starting a frequency hopping or improving the working mode of working signal intensity; the touch screen starts a working mode of frequency hopping or improving the working signal intensity.

the fingerprint recognizer sends fourth information to the touch screen, wherein the fourth information comprises a working mode of the fingerprint recognizer; the touch screen determines the working mode of the fingerprint identifier as a preset working mode according to the fourth information; the touch screen starts a working mode of frequency hopping or improving the working signal intensity.

and the fingerprint recognizer sends fourth information to the touch screen through the processor, wherein the fourth information comprises the working mode of the fingerprint recognizer.

if the working mode of the fingerprint identifier is the preset working mode, the touch screen starts to detect the interference signal, and starts the working mode of frequency hopping or improving the working signal intensity.

It should be noted that the touch screen may start to detect the interference signal when the terminal is powered on, or may start to detect the interference signal when the terminal is in a bright screen state. The touch screen can also start detecting the interference signal after receiving the first information sent to the touch screen by the fingerprint recognizer. Specifically, the fingerprint identifier may notify the touch screen to start detecting the interference signal when determining that the fingerprint identifier is in the legal unlocking working mode or any working mode in the unlocking state of the touch screen according to the working mode of the fingerprint identifier. Or the fingerprint recognizer sends the self working mode to the touch screen, and the touch screen determines whether to start detecting the interference signal. And if the fingerprint identifier is determined to be in the legal unlocking working mode or any working mode in the unlocking state, the touch screen starts to detect the interference signal. Therefore, the time for detecting the interference signal by the touch screen is relatively short, and the power consumption of the terminal is further reduced.

It should be further noted that the second module may simultaneously start the operation mode of detecting the interference signal and starting the frequency hopping or increasing the strength of the operation signal. Or the working mode of detecting the interference signal and then starting frequency hopping or improving the working signal intensity can be started.

In some embodiments of the present application, the fingerprint recognizer may be disposed on the back side of the terminal 100 (e.g., below the rear facing camera), or the fingerprint recognizer may be disposed on the front side of the terminal 100 (e.g., below the display screen 194). For another example, a fingerprint recognizer may be configured in the display screen 194 to realize the fingerprint recognition function, that is, the fingerprint recognizer may be integrated with the display screen 194 to realize the fingerprint recognition function of the terminal 100. In this case, the fingerprint recognizer is disposed in the display 194, may be a part of the display 194, or may be otherwise disposed in the display 194. The fingerprint identifier in the embodiments of the present application may employ any type of sensing technology including, but not limited to, optical, capacitive, piezoelectric, or ultrasonic sensing technologies, etc.

Taking the fingerprint recognizer as a capacitive fingerprint sensor as an example, similarly, the structure of the fingerprint recognizer may be similar to that of a touch device in a touch screen, and the fingerprint recognizer is smaller in size. The fingerprint recognizer is used for detecting the lines of the fingerprint, the actual distances between the convex points and the concave points contacting the flat plate are different due to the fact that the lines of the finger are uneven, the formed capacitance/inductance values are different, and the fingerprint recognizer can detect the pattern of the fingerprint. The fingerprint recognizer outputs a touch signal, collects different collected capacitance detection values according to the principle, and sends the collected different capacitance detection values to the processor 110 to finish fingerprint collection. And comparing the detected pattern with one of one or more prestored fingerprint patterns to determine whether the detected pattern is the same as one of the prestored fingerprint patterns so as to verify the fingerprint and further execute other interactive actions.

The detected touch operation may be passed to an application processor to determine the touch event type and provide a corresponding visual output via the display screen.

In some embodiments of the present application, the touch sensor 180K may also constitute a touch screen of the terminal 100 together with the display screen 194. Among other things, the touch sensor 180K may collect touch events on or near the terminal 100 by a user (e.g., user operation on or near the touch sensor 180K using any suitable object such as a finger, a stylus, etc.) and transmit the collected touch information to other devices (e.g., the processor 110). Among them, the touch event of the user near the touch sensor 180K may be called a hover touch; hover touch may refer to a user not having to directly contact the touch sensor 180K in order to select, move, or drag a target (e.g., an icon, etc.), but rather only having to be in proximity to the device in order to perform a desired function. In addition, the touch sensor 180K may be implemented using various types of resistive, capacitive, infrared, and surface acoustic waves. Taking a capacitive touch screen as an example, the capacitive touch screen includes an insulator covered by a transparent conductor formed on a specific layout. When a finger or other object touches the screen surface, the capacitance changes, and the processor 110 can determine the location of the touch by detecting the change in capacitance.

For example, touch operations applied to different applications (e.g., photographing, audio playing, etc.) may correspond to different vibration feedback effects. The touch operation on different areas of the display screen can also correspond to different vibration feedback effects. Different application scenes (such as time reminding, receiving information, alarm clock, game and the like) can also correspond to different vibration feedback effects. The touch vibration feedback effect may also support customization.

Fig. 4 is a schematic external view of the terminal 100. The terminal 100 comprises a touch screen 401 and a fingerprint identifier 402. A graphical user interface is displayed on the touch screen 401. Such as icons 403 of the various applications exemplarily shown in fig. 4.

In some embodiments, as shown in FIG. 4, touch screen 401 and fingerprint identifier 402 may be located in two areas of the same face of terminal 100. In other embodiments, the touch screen 401 and the fingerprint identifier 402 may be located on two opposite sides of the terminal 100, for example, with the touch screen 401 on the front and the fingerprint identifier 402 on the back. In still other embodiments, the touch screen 401 and the fingerprint identifier 402 may also be located in the same area, and are not described again.

The following describes exemplary work flows of software and hardware of the terminal 100 in conjunction with specific scenarios of embodiments of the present application.

In some embodiments of the application, after the fingerprint identifier detects the touch operation, the fingerprint identifier collects fingerprint information of a user, and the fingerprint identifier compares the collected fingerprint information with pre-stored legal fingerprint information. And after the comparison is successful, the fingerprint identifier reports the comparison result to the corresponding application in the application layer through the kernel layer. When the terminal 100 is in the lock screen state, the application unlocks the screen. And calling a display driver in the kernel layer, and displaying the unlocked interface of the terminal through the touch screen.

When the fingerprint identifier reports the comparison result to the corresponding application in the application layer through the kernel layer, or before or after the comparison result is reported, the fingerprint identifier sends the legal unlocked working mode of the fingerprint identifier to the touch screen, so that the touch screen determines whether to start the working mode of frequency hopping or working signal strength improvement. For the detailed operation and interaction of the fingerprint recognizer and the touch screen, reference is made below.

In other embodiments of the present application, after the fingerprint identifier detects a touch operation, when the terminal 100 is in an unlocked state, the fingerprint identifier may be triggered to report a touch event (for example, parameters such as a touch point position and time) generated by the touch action of the user to the kernel layer through a corresponding driver, and the kernel layer encapsulates the touch event and then calls a corresponding API to distribute the touch event to an application of the application layer. And the application of the application layer executes different operations according to different touch operations, calls the display drive in the kernel layer and displays a corresponding interface through the touch screen.

And the fingerprint identifier reports the touch event generated by the touch action of the user to the kernel layer through corresponding driving, and simultaneously, before or after the touch event, the fingerprint identifier sends the unlocked working mode to the touch screen, so that the touch screen determines whether to start the working mode of frequency hopping or working signal strength improvement. For the detailed operation and interaction of the fingerprint recognizer and the touch screen, reference is made below.

The methods in the following embodiments may be implemented in the terminal 100 having the above-described hardware configuration and software configuration.

Considering that the touch screen and the fingerprint recognizer are two modules which are frequently used by a user, the interference between the touch screen and the fingerprint recognizer is taken as an example, and the principle of causing the interference between the modules is briefly explained below.

Under the condition that the touch screen and the fingerprint recognizer are both in working states, when the finger 1 of the user touches the fingerprint recognizer and the finger 2 also touches the touch screen at the same time, the human body of the user forms a circuit diagram as shown in fig. 3 with the terminal and the ground (PE).

Wherein, when the finger 1 touches the fingerprint recognizer (may be abbreviated as "fingerprint device"), the surface of the finger 1 and the surface layer of the fingerprint recognizer form a capacitor C_f. Similarly, when the finger 2 touches the touch screen, the surface of the finger 2 and the surface layer of the touch screen form a capacitor C_t. The body resistance between finger 1 and finger 2 is R₂. The equivalent capacitance of the touch screen to the terminal Ground (GND) is C_tpi. Apparently, the body resistance R₂Capacitor C_fCapacitor C_tAnd C_tpiA closed path is formed, i.e. an interference path. That is, at this time, the electromagnetic wave generated when the fingerprint recognizer operates is conducted to the touch screen through the closed path. If the working frequency of the fingerprint identifier coincides with the working frequency of the touch screen at this time, the working signal of the fingerprint identifier interferes with the touch screen.In other words, from the perspective of the touch screen, the working signal of the fingerprint recognizer at this time can be regarded as an interference signal of the touch screen. When the working signal intensity of the fingerprint identifier reaches a certain threshold value, the working of the touch screen is abnormal. For example: the phenomena of no response to touch on the touch screen, dialing linkage, screen jumpiness and the like occur.

Similarly, the electromagnetic wave of touch-sensitive screen during operation also can be conducted fingerprint identification ware department through this closed route, if the operating frequency of fingerprint identification ware and touch-sensitive screen operating frequency coincidence this moment, the operating signal of touch-sensitive screen can cause the interference to fingerprint identification ware. In other words, from the perspective of the fingerprint identifier, the working signal of the touch screen at this time can be regarded as an interference signal of the fingerprint identifier. When the working signal intensity of the finger touch screen reaches a certain threshold value, the fingerprint identifier works abnormally. For example: and the phenomenon that the fingerprint unlocking fails or the touch fingerprint recognizer does not react occurs.

Here, taking the example that the fingerprint recognizer interferes with the touch screen, a method for reducing interference of the fingerprint recognizer by the touch screen is exemplified.

First, in order to better understand the interference of the fingerprint recognizer on the touch screen, the interference signal caused by the fingerprint recognizer is quantized. Still referring to fig. 3, the fingerprint recognizer can calculate the interference voltage V of the touch screen from the fingerprint recognizer according to the existing calculation method_f。

Wherein, C_mThe capacitance of the human body to earth ground is about 100 picofarads (pF). C_sThe terminal to ground capacitance is about 10 pF. C_hThe capacitance of the human body to the mobile phone is usually larger than 1 pF. C_fIs the capacitance of the finger to the fingerprint identifier. C_tIs the capacitance of the finger to the touch screen, typically 5 pF. R₁Which is a body resistance, is typically located at 330 to 2000 ohms (ohms). R₂And R ₃The resistance inside the human body is about 5000 ohms. C_tpiThe equivalent capacitance of the touch screen self-capacitance to terminal ground is typically less than 1 pF. V₁Is the working voltage of the fingerprint recognizer.

Because the fingerprint recognizer and the touch screen have working frequencies between 50 kilohertz (kHz) and 1 megahertz (MHz), R₁、R ₂、R ₃And C_mCan be ignored. And, due to the capacitance C of the touch screen_tp＝C _tC _tpi/(C _t+C _tpi). Then, the interference voltage V caused by the fingerprint recognizer to the touch screen_fThe following can be written:

as can be seen from the above formula, the voltage intensity of the interference signal is positively correlated with the working voltage of the fingerprint identifier. The voltage strength of the interference signal is also related to the capacitance formed by the finger and the fingerprint identifier when the user touches the fingerprint identifier. The voltage intensity of the interference signal is also related to capacitance formed by fingers of a user touching the touch screen and the touch screen, and is not repeated.

Therefore, the touch screen can detect the interference signal, and when the interference signal is detected to meet the preset condition, a corresponding method for reducing the interference is adopted.

In some embodiments of the present application, when the touch screen detects that the interference signal satisfies the preset condition, the interference of the fingerprint identifier to the touch screen may be reduced by a frequency hopping method. The reason is that when the touch screen detects that the interference signal meets the preset condition, the current working frequency of the touch screen is close to the frequency of the interference signal, so that the touch screen can hop frequency, that is, the touch screen switches the current working frequency to another frequency, and the switched working frequency can not coincide with the interference frequency, thereby avoiding mutual interference between the two module assemblies.

In other embodiments of the present application, when the touch screen detects that the interference signal satisfies the preset condition, the interference of the fingerprint identifier on the touch screen may be reduced by increasing the strength of the working signal. The reason is that after the strength of the working signal of the touch screen is improved, the strength of the interference signal is not enough to cause the abnormal working of the touch screen, which is equivalent to that the interference of the fingerprint identifier is reduced by the touch screen.

In still other embodiments of the present application, when the interference signal is detected to satisfy the preset condition, the fingerprint identifier may also reduce its interference to the touch screen by frequency hopping or reducing the strength of the working signal. In a similar way, the frequency hopping of the fingerprint identifier can enable the working frequency of the touch screen and the working frequency of the fingerprint identifier not to be overlapped, and then mutual interference between the two module assemblies is avoided. In addition, according to the voltage formula of the interference signal, after the fingerprint identifier reduces the intensity of the working signal, the intensity of the interference signal is reduced, and the interference effect is not enough to cause the abnormal working of the touch screen.

The working signal of the touch screen is used for detecting touch, and the working signal of the fingerprint recognizer is used for detecting touch.

It is noted that a touch screen typically comprises a touch layer and a display screen. Wherein the primary component of the touch layer is a touch sensor. In the embodiment of the application, the touch screen is mainly interfered by the touch sensor of the touch layer. Therefore, when the touch screen reduces the interference of the fingerprint identifier by adopting a frequency hopping mode, the touch sensor of the touch layer hops frequency, so that the working frequency of the touch sensor is not coincident with the working frequency of the fingerprint identifier. When the touch screen reduces the interference of the fingerprint identifier by adopting a method of improving the intensity of the working signal, the method also mainly aims to improve the intensity of the working signal of the touch sensor of the touch screen. Similarly, when the fingerprint identifier is used for frequency hopping to reduce interference to the touch screen, the working frequencies of the fingerprint identifier and the touch sensor on the touch layer are not overlapped. That is to say, in the embodiment of the present application, the working frequency of the touch screen mainly refers to the working frequency of the touch sensor of the touch layer, and the working signal of the touch screen also mainly refers to the working signal of the touch sensor of the touch layer, which is not described in detail below.

Considering that if the terminal is in a power-on state and the touch screen is in a bright screen state, the touch screen always starts a working mode of frequency hopping or improving the intensity of a working signal, the touch screen periodically judges whether the interference signal detected by the touch screen meets a preset condition, and when the preset condition is met, the touch screen frequency hops or improves the intensity of the working signal. Under the working mode, the touch screen periodically judges whether the interference signal meets the preset condition or not, and the power consumption is larger. Therefore, in the technical scheme provided by the embodiment of the application, the touch screen can start the frequency hopping of the touch screen or improve the working mode of the working signal intensity when the fingerprint identifier and the touch screen are both in the working state, that is, the touch screen can periodically judge whether the interference signal detected by the touch screen meets the preset condition when the fingerprint identifier and the touch screen are both in the working state, and the frequency hopping or the working signal intensity improvement of the touch screen is performed after the preset condition is met. Generally, the touch screen is in an operating state, the fingerprint identifier is in the operating state less frequently, and the time is short, so that the method provided by the embodiment of the application can greatly reduce the power consumption of the terminal.

The above-mentioned interference exists when both the fingerprint identifier and the touch screen are in operation and are touched at the same time. Therefore, the following description will briefly describe the case where the fingerprint recognizer and the touch screen are both in an operating state in conjunction with the operating process of the fingerprint recognizer in the terminal.

As shown in (1) in fig. 16, it is a timing diagram illustrating the operation process of the fingerprint recognizer and the touch screen in the terminal. The method comprises the following specific steps:

in the time period from the time t1 to the time t2, the terminal is in a dormant state, the terminal is in a screen-off state, and at the time, the fingerprint identifier and the touch screen are both in the dormant state.

At time t2, the terminal detects a touch operation of the fingerprint recognizer by the user, and wakes up the fingerprint recognizer. The fingerprint recognizer reads fingerprint information of a user and compares the fingerprint information with a prestored fingerprint. If the comparison fails, the terminal is continuously in a screen locking state; in some embodiments of the application, if the comparison fails, the terminal may continue to keep the screen-off state. At this time, the fingerprint recognizer is in a working state, and the touch screen is still in a dormant state. In other embodiments of the present application, if the comparison fails, the terminal may light up the screen, and at this time, the screen displays the screen locking interface. As shown in (2) of fig. 16, after the terminal detects the touch operation of the fingerprint recognizer by the user at time t2, the fingerprint sensor is in an operating state, and the terminal lights up the screen at time t 7. In the time period from the time t7 to the time t8 (the time t8 is that the terminal is turned off), the fingerprint recognizer and the touch screen are both in an operating state. It can be understood that, at this time, the operations that the user can perform on the lock screen interface are limited, so that the situation that the touch screen is in the working state at this time may not be considered. After a certain time, i.e. at time t8, the terminal goes off the screen. And from the time t8 to the time t9, the fingerprint identifier is in an operating state, and the touch screen is in a non-operating state. It will be appreciated that the fingerprint identifier may also sleep before the terminal is turned off.

And if the comparison is successful, unlocking the terminal (at the moment t 3), at the moment, awakening the touch screen, displaying the main interface or other interfaces, and at the moment, enabling the fingerprint identifier to be in a legal unlocking working mode. At this time, the fingerprint recognizer is in a working state, and the touch screen is also in a working state. When the terminal is in the unlocked state, if the operation that the user touches the fingerprint identifier again is not detected within a period of time, the fingerprint identifier enters the dormant state again at the time t4, and the touch screen is still in the working state at this time.

It will be appreciated that from the successful unlocking of the terminal to the time when the fingerprint identifier again enters the sleep state (i.e. the time period from time t3 to time t 4), both the fingerprint identifier and the touch screen are in the active state. If during this time the terminal detects that the user touches both the fingerprint identifier and the touch screen, the above mentioned interference may occur.

And continuing to wake up the fingerprint identifier if the fingerprint identifier is detected to be touched by a user when the fingerprint identifier is in a dormant state under the condition that the terminal is in an unlocked state. At this time, both the fingerprint recognizer and the touch screen are in working states. The operation of the user touching the fingerprint recognizer may be a long press, double click, swipe, etc. The fingerprint recognizer recognizes a specific operation gesture and executes a corresponding instruction.

It will be appreciated that in the unlocked state of the terminal, both the fingerprint identifier and the touch screen are in an operative state after the fingerprint identifier is touched at time t 5. Such interference may occur if the terminal detects that the user touches the fingerprint recognizer and the touch screen simultaneously during the period of time (the period of time from time t5 to time t 6).

By combining the characteristic that the fingerprint identifier and the touch screen interfere with each other, the embodiment of the application provides a method for operating the touch device, so that when the fingerprint identifier and the touch screen are both in a working state, the touch screen starts a working mode of frequency hopping or improving the working signal intensity.

As shown in fig. 5, a schematic flow chart of a method for operating a touch device is provided for an embodiment of the present application, where the method includes: S101-S105, specifically as follows:

s101, the first module is in a dormant state.

Wherein the first mold assembly is a mold assembly that causes interference with the second mold assembly. For example: the first mold assembly may be a fingerprint recognizer and the second mold assembly may be a touch screen.

S102, the first module component detects the touch operation and is awakened.

Illustratively, the first module is a fingerprint recognizer. Then, after detecting the touch operation of the user to the fingerprint recognizer, the fingerprint recognizer is awakened and starts to work. For example: the fingerprint recognizer starts to detect the lines of the user fingerprint and compares the lines with the pre-stored fingerprint; recognizing an operation gesture of a touch operation, for example: long press, click, double click, slide, etc.; and determining different operations according to different operation gestures, and the like.

S103, the first module sends first information to the second module.

In some embodiments of the present application, as shown in fig. 6, the first information may be an operation mode of the first mold assembly. That is, the first module directly transmits its own operation mode to the second module, and the second module determines whether to start the operation mode of frequency hopping or increasing the strength of the operation signal. After determining the operation mode of frequency hopping or increasing the operation signal strength (shown as step S104a in fig. 6) that the second module needs to be turned on, the second module turns on the operation mode of frequency hopping or increasing the operation signal strength.

Taking the first module as a fingerprint identifier and the second module as a touch screen as an example, the first information may specifically be that the fingerprint identifier is in a working mode of legal unlocking, and the fingerprint identifier is in working modes of long pressing, clicking, double clicking, sliding and the like in an unlocking state of the touch screen. Specifically, the processor can inform the fingerprint identifier in advance that the terminal is currently in a screen locking state or an unlocking state. After detecting the touch operation, the fingerprint identifier determines the working mode of the fingerprint identifier according to the screen locking state or the unlocking state of the terminal. For example: the terminal is in a screen locking state, and the fingerprint recognizer collects fingerprint information of a user after detecting touch operation and compares the collected fingerprint information with prestored legal fingerprint information. If the comparison is successful, the fingerprint identifier is reported to the processor. The processor unlocks the terminal screen. Then the fingerprint identifier may determine to operate in a legally unlocked operating mode. Another example is: the terminal is in an unlocked state, and then after the fingerprint identifier detects a touch operation, the fingerprint identifier reports the touch event (including information such as touch coordinates and a time stamp of the touch operation) to the processor, and the processor executes different operations according to different touch events. The fingerprint identifier may then determine to operate in an operating mode such as a long press, click, double click, or swipe in the unlocked state.

And then, the second module determines whether the second module needs to be started in a frequency hopping mode or a working mode for improving the working signal strength according to the working mode of the first module.

In other embodiments of the present application, as shown in fig. 7, the first information may be used to inform the second module to turn on the frequency hopping or the operation mode of increasing the operating signal strength of the second module. That is to say, after the first module detects the touch operation, it is determined whether the second module needs to start the frequency hopping or the working mode of increasing the working signal strength. After determining that the second module needs to turn on the frequency hopping or working signal strength increasing working mode (shown as 103c in fig. 7), the second module is informed to turn on the frequency hopping or working signal strength increasing working mode.

The determining, by the first module, a working mode in which the second module needs to be turned on or the working signal strength is improved specifically includes: the first module determines the working mode of the first module, and further determines whether the first module and the second module are both in working states. If the first module assembly and the second module assembly are in working states, the first module assembly determines a working mode that the second module assembly needs to be opened frequently or the working signal strength is improved, so that the interference between the two module assemblies is reduced.

Still taking the first module as a fingerprint recognizer and the second module as a touch screen as an example, the fingerprint recognizer determines its own working mode after being awakened. For a specific method for determining the working mode, reference may be made to the above description, and details are not repeated here. When the fingerprint identifier determines that the fingerprint identifier is in a legal unlocking mode or any working mode in the unlocking state (working modes such as long press, click, double click or sliding in the unlocking state) the fingerprint identifier can determine that the touch screen is also in the working state, so that the fingerprint identifier can inform the touch screen of starting the working mode of frequency hopping or improving the working signal intensity so as to reduce or reduce the interference between the two module assemblies.

And S104, the second module starts a working mode of frequency hopping or working signal strength improvement.

In some embodiments of the present application, the second module receives first information sent by the first module, where the first information is a working mode for notifying the second module to start frequency hopping or improve working signal strength, and then the second module starts the working mode for frequency hopping or improving working signal strength.

In other embodiments of the present application, after the second module receives the first information sent by the first module, and the first information is the working mode of the first module, the second module needs to determine whether to start the frequency hopping or improve the working mode of the working signal strength. And then step S104 is performed. The specific determination method of the second module is similar to the determination method of the first module in step S103c, and is not repeated here.

It should be noted that, before step S104, the second module may start to detect the interference signal. The first mold assembly is a fingerprint device, and the second mold assembly is a touch screen. For example, the touch screen may start to detect the interference signal when the terminal is powered on, or may start to detect the interference signal when the terminal is in a bright screen state or an unlocked state. The touch screen may also start detecting the interference signal in step S103 after receiving the first information sent to the touch screen by the fingerprint identifier. Specifically, the fingerprint identifier may determine that the fingerprint identifier is in a legal unlocking working mode according to a working mode of the fingerprint identifier, or notify the touch screen to start detecting the interference signal in any working mode in an unlocking state. Or the fingerprint recognizer sends the self working mode to the touch screen, and the touch screen determines whether to start detecting the interference signal. And if the fingerprint identifier is determined to be in the legal unlocking working mode or any working mode in the unlocking state, the touch screen starts to detect the interference signal. Therefore, the time for detecting the interference signal by the touch screen is relatively short, and the power consumption of the terminal is further reduced. The embodiment of the present application does not limit this.

And continuously, after the second module starts a frequency hopping or working mode for improving the working signal strength, the detection result of the second module on the interference signal is inquired at intervals. If the second module detects that the interference signal satisfies the predetermined condition, step S105 is executed. Otherwise, the second module component continuously inquires the detection result of the second module component to the interference signal at intervals.

Optionally, in further embodiments of the present application, if the second module detects that the interference signal does not satisfy the predetermined condition within a predetermined time period, it may be considered that the first module still does not cause interference to the second module or the interference does not affect normal operation of the second module within a time period after the predetermined time period. The second mode component may then turn off the frequency hopping or increased signal strength mode of operation. Therefore, the terminal power consumption is saved, and the response speed of the second module assembly is improved.

Optionally, in further embodiments of the present application, taking the first module as a fingerprint identifier and the second module as a touch screen as an example, if the touch screen detects that the interference signal does not meet the preset condition all the time within a preset time period and the fingerprint identifier does not detect the touch operation again, the touch screen may close the frequency hopping or increase the working mode of the working signal intensity.

Optionally, in further embodiments of the present application, taking the first module as a fingerprint identifier and the second module as a touch screen as an example, if the touch screen acquires that the fingerprint identifier is in a sleep state or the touch screen detects a screen locking operation of a user, the touch screen turns off a frequency hopping mode or an operating mode that improves an intensity of an operating signal. The reason is that the fingerprint identifier is in a dormant state or the touch screen is in a screen locking state, which indicates that the fingerprint identifier and the touch screen are not in a working state at the same time, mutual interference cannot occur, and therefore, the touch screen closes a working mode of frequency hopping or improving the working signal strength so as to reduce the power consumption of the terminal. The fingerprint recognizer acquired by the touch screen is in the dormant state, wherein the fingerprint recognizer transmits information of the dormant state to the touch screen, and the information of the fingerprint recognizer in the dormant state can be actively acquired by the touch screen. The embodiments of the present application are not limited. The touch screen and the fingerprint recognizer can be in direct communication, and can also be in indirect communication through other hardware. The screen locking operation of the user may be a click operation of the screen locking button by the user.

For example: referring to fig. 16 (1), when the terminal is in the screen-locked state, the fingerprint identifier is touched at time t2, the user fingerprint information is collected, the validity of the user fingerprint information is verified, it is determined that the terminal operates in the legal unlocking operating mode at time t3, and then the touch screen starts the operating mode of frequency hopping or increasing the intensity of the operating signal. The fingerprint recognizer is dormant at time t4, and the touch screen turns off the frequency hopping or working mode for increasing the working signal strength. That is, the touch screen starts the operation mode of frequency hopping or increasing the intensity of the operation signal from time t3 to time t 4.

Another example is: referring to (1) in fig. 16, when the terminal is in the unlocked state, the fingerprint recognizer is touched at time t5, the fingerprint recognizer determines that the operation mode is the operation mode in the unlocked state, and then the touch screen starts the operation mode of frequency hopping or increasing the intensity of the operation signal. The fingerprint recognizer is dormant at time t6, and the touch screen turns off the frequency hopping or working mode for increasing the working signal strength. That is, the touch screen starts the operation mode of frequency hopping or increasing the intensity of the operation signal from time t5 to time t 6. And S105, the second module hops or increases the working signal strength.

The preset condition means that the frequency of the interference signal is within the sensitive frequency interval of the second module, and the strength of the interference signal reaches a threshold value. The sensitive frequency range of the second module is a range around the fundamental frequency or odd harmonic of the operating signal of the second module, and may be, for example, 0.9 to 1.1 times of the operating frequency of the second module.

In some embodiments of the present application, the terminal may set a plurality of preselected frequency hopping points. For example: the second module works at frequency point 1, and the preselected frequency points comprise frequency point 2, frequency point 3 and the like. When the second module works at the frequency point 1, an interference signal is detected, and the interference signal meets a preset condition, the second module switches the working frequency point to the frequency point 2. And if the working frequency point is switched to the frequency point 3 again, the second module still detects the interference signal and the interference signal meets the preset condition when the working frequency point is switched to the frequency point 2. And so on until the interference signal is not enough to affect the normal operation of the second module. In other embodiments of the present application, the terminal may set one frequency point interval. When the second module detects an interference signal and the interference signal satisfies a preset condition, the working frequency point of the second module can be switched according to a certain algorithm in the frequency point interval, for example: switching is performed in linear steps of fixed value (e.g. 2 kHZ). The embodiment of the application does not limit the specific frequency hopping mode of the touch screen.

For example, taking the second module as a touch screen as an example, the specific frequency hopping may be implemented by a crystal oscillator and a frequency divider inside a touch sensor in the touch screen, and by adjusting a counter. For a specific implementation of frequency hopping, reference may be made to the prior art, and details are not repeated here.

For example, taking the second module as a touch screen, the second module can increase the working signal strength by adjusting the output level through a budget amplifier portion in the touch screen sensor.

Therefore, in the scheme provided by the embodiment of the application, when it is determined that both the first module and the second module are in the working state, the second module starts the working mode of frequency hopping or improving the strength of the working signal. And then, after the detected interference signal is determined to meet the preset condition, the second module hops frequency or improves the working signal intensity, and then the interference between the first module and the second module is reduced.

Furthermore, in the embodiment of the present application, when either one of the first module and the second module is in a non-operating state (including a sleep state, an off state, etc.) or both of the first module and the second module are in a non-operating state, the terminal may not turn on (or turn off) the operating mode of frequency hopping or increasing the operating signal strength. For example: when the fingerprint recognizer is in a dormant state, the fingerprint recognizer can be considered to be in a non-working state, and at the moment, the touch screen does not start (or close) a working mode of frequency hopping or improving the working signal intensity. Another example is: the touch screen is in a screen-off state or a screen-locking state, and the touch screen can be considered to be in a non-working state, and at the moment, the touch screen can not start (or close) a working mode of frequency hopping or improving the working signal intensity. Therefore, the time for the second module to start the frequency hopping or improve the working mode of the working signal strength is reduced, the time for the second module to periodically query the interference signal and judge whether the interference signal meets the preset condition is reduced, the power consumption of the terminal is saved, and the response speed of the second module is improved.

It should be noted that the first module may communicate with the second module directly or indirectly through an intermediate module. Step S103 may be replaced with steps S103a-S103 b.

As shown in fig. 8, a schematic flow chart of a method for operating a touch device is provided in an embodiment of the present application, where the method further includes: S101-S102, S103a, S103b, and S104-S105, as follows:

s103, 103a, the first module sends first information to the processor.

For example, the processor may be specifically an application processor or a System On Chip (SOC), where the processor may also be other hardware that is in communication connection with both the first module and the second module, and the embodiment of the present application is not limited thereto.

In some embodiments of the present application, the first information may be an operation mode of the first module, and the processor may further determine whether to notify the second module of an operation mode of turning on frequency hopping or increasing an operation signal strength according to the operation mode of the first module. The determination method of the processor is similar to the determination method of the first module in step S103c, and is not described herein again.

Optionally, the processor may also directly send the operating mode of the first module to the second module, and the second module determines whether to start the operating mode of frequency hopping or improving the operating signal strength. The specific determination method of the second module is similar to the determination method of the first module in step S103c, and is not repeated here.

In other embodiments of the present application, the first information is an operation mode for informing the second module to start frequency hopping or increase the strength of an operation signal of the second module. The processor may forward the notification directly to the second module component.

S103, 103b, the processor sends second information to the second module.

In some embodiments of the present application, as shown in fig. 9, the first information may include an operation mode of the first module (shown as step S103a in fig. 9), and the processor determines whether to notify the second module of the operation mode of turning on frequency hopping or increasing the strength of the operation signal (shown as step S103d in fig. 9) according to the first information, and then the second information is different from the first information, and the second information is an operation mode of notifying the second module of turning on frequency hopping or increasing the strength of the operation signal (shown as step S103b in fig. 9).

In other embodiments of the present application, as shown in fig. 10, the first information may include an operation mode of the first module (shown as step S103a in fig. 10), and the processor directly transmits the operation mode of the first module to the second module (shown as step S103b in fig. 10), so that the second information may be the same as the first information and is the operation mode of the first module.

In still other embodiments of the present application, as shown in fig. 11, when the first information is an operation mode for informing the second module to turn on frequency hopping or increase the strength of the operation signal, the second information may be the same as the first information, and is an operation mode for informing the second module to turn on frequency hopping or increase the strength of the operation signal (shown in steps S103a and S103b in fig. 11).

And the second module component receives second information sent by the processor. In some embodiments of the present application, the second information is an operating mode of the first module, and the second module needs to determine whether to start the operating mode of frequency hopping or increasing the operating signal strength, and then execute step S104. In other embodiments of the present application, the second information is an operation mode for informing the second module to start frequency hopping or to improve the strength of the operation signal, and the second module directly performs step S104.

For other contents, reference may be made to relevant contents of the above embodiments, and repeated descriptions are omitted.

Optionally, after the interference signal is detected to meet the preset condition, the frequency of the first module may be hopped or the working signal strength of the first module may be reduced. That is, step S105 may be replaced with steps S106-S107.

As shown in fig. 12, a schematic flowchart of a method for operating a touch device is provided in an embodiment of the present application, where the method includes: S101-S103, S104, S106, and S107, or as shown in fig. 13, the method includes: S101-S102, S103a, S103b, S104, S106a, S106b, and S107, as follows:

and S106, if the second module detects that the interference signal meets the preset condition, the second module sends third information to the first module.

The third information may be used to inform the first module to hop frequency or reduce the working signal strength of the first module. The third information may also be a notification of the first module, and the interference of the first module on the second module also satisfies a preset condition, so that the first module determines frequency hopping or reduces the working signal strength of the first module.

Similarly, the second module may communicate directly with the first module or indirectly via other modules. That is, step S106 may be replaced with steps S106a and S106 b.

S106, 106a, if the second module detects that the interference signal meets the preset condition, the second module sends third information to the processor.

For example, the processor may specifically apply to a processor, or a System On Chip (SOC), where the processor may also be other hardware that is in communication connection with both the first module and the second module, and the embodiment of the present application is not limited thereto.

S106, the processor sends fourth information to the first module assembly.

The fourth information and the third information may have the same content, and are used to inform the first module to hop frequency or reduce the working signal strength of the first module. The third information may also be a notification to the first module, and the interference of the first module on the second module satisfies a preset condition, so that the first module determines frequency hopping or reduces the working signal strength of the first module.

And S107, the first module hops or reduces the strength of the working signal.

In some embodiments of the present application, the terminal may set a plurality of preselected frequency hopping points. For example: the first module works at frequency point 4, and the preselected frequency points comprise frequency point 5, frequency point 6 and the like. When the first module works at the frequency point 4, the second module detects an interference signal, and the interference signal meets a preset condition, then the first module switches the working frequency point to the frequency point 5. And if the working frequency point is switched to the frequency point 6 again, the second module still detects the interference signal and the interference signal meets the preset condition when the working frequency point is switched to the frequency point 5. And so on until the interference signal is not enough to affect the normal operation of the second module. In other embodiments of the present application, the terminal may set one frequency point interval. When the second module detects an interference signal and the interference signal satisfies a preset condition, the working frequency point of the first module can be switched according to a certain algorithm in the frequency point interval, for example: switching is performed in linear steps of fixed value (e.g. 2 kHZ). The embodiment of the application does not limit the specific frequency hopping mode of the touch screen.

For example, taking the first module as fingerprint identification, the specific frequency hopping can be realized by a crystal oscillator and a frequency divider inside the fingerprint sensor, and by adjustment of a counter. For a specific implementation of frequency hopping, reference may be made to the prior art, and details are not repeated here.

For example, taking the first module as the fingerprint recognizer, the first module may reduce the working signal strength by adjusting the output level through a budget amplifier portion in the fingerprint sensor.

Other contents of the embodiments of the present application may refer to related contents of the above embodiments, and are not repeated.

Further, it is considered that the fingerprint identifier and the touch screen are both in a working state, and when the fingerprint identifier and the touch screen are touched simultaneously, mutual interference exists between the fingerprint identifier and the touch screen. Therefore, the frequency hopping of the touch screen can be started or the working mode of the working signal intensity can be improved only when the touch screen is in the working state and the touch is detected. Therefore, the frequency hopping of the terminal for starting the touch screen or the working time for improving the working signal intensity can be reduced, and the power consumption of the terminal is reduced.

That is to say, an embodiment of the present application further provides a method for operating a touch device, as shown in fig. 14, the method specifically includes steps S201 to S203, as follows:

s201, detecting that the touch screen is in a working state and is touched.

For example, when the terminal detects that the touch screen receives an unlocking instruction or the touch screen is in an unlocking state, the touch screen may be considered to be in a working state. The method for detecting that the touch screen receives the unlocking instruction comprises the following steps: the fingerprint recognizer detects the legal fingerprint information of the user when being in a legal unlocking working mode, and after the legal fingerprint information is compared successfully, an unlocking instruction is sent to the touch screen or the touch screen through the processor.

S202, the touch screen starts a working mode of frequency hopping or working signal strength improvement.

Before or simultaneously with this step, the touch screen starts to detect the interference signal, specifically, the frequency of the interference signal and the intensity of the interference signal. And after the touch screen starts a working mode of frequency hopping or working signal intensity improvement, the touch screen periodically reads the detection result.

S203, if the interference signal is detected to meet the preset condition, the touch screen hops or the working signal intensity is improved.

The preset condition is that the frequency of the interference signal is within a sensitive frequency range of the working frequency of the touch screen (that is, the frequency of the interference signal is close to the working frequency of the touch screen), and the intensity of the interference signal reaches a certain threshold. This is because the interference signal is located in the sensitive range of the operating frequency of the touch screen, and the interference signal affects the operation of the touch screen. The intensity of the interference signal reaches a certain threshold value, which can cause the abnormal operation of the touch screen.

Optionally, after the interference signal is detected to meet the preset condition, the fingerprint identifier may hop frequency or reduce the working signal intensity of the fingerprint identifier, so as to reduce the interference of the fingerprint identifier on the touch screen. That is, step S203 may be replaced with steps S203a-S203 b. That is, the working method of the touch device specifically includes steps S201-S202, 203a and S203b, as follows:

s203a, if the interference signal is detected to meet the preset condition, the touch screen sends fourth information to the fingerprint recognizer.

Wherein the fourth information may be used to inform the fingerprint recognizer to hop frequencies or reduce the working signal strength of the fingerprint recognizer. The fourth information may also be a notification to the fingerprint identifier, and the interference of the fingerprint identifier to the touch screen also satisfies a preset condition, so that the fingerprint identifier determines frequency hopping or reduces the working signal strength.

S203b, the fingerprint recognizer hops or reduces the working signal strength.

This step can refer to step S107.

It will be appreciated that the touch screen may communicate directly with the fingerprint identifier or indirectly through other hardware such as a processor. That is to say, S203a may be replaced by S204 and S205, as shown in fig. 15, which is a flowchart illustrating a working method of another touch device provided in the embodiment of the present application, and the method specifically includes: S201-S202, S204-S205, S203b, specifically as follows:

and S204, if the interference signal is detected to meet the preset condition, the touch screen sends fifth information to the processor.

For example, the processor may be specifically an application processor or an SOC, where the processor may also be other hardware that is in communication connection with both the touch screen and the fingerprint identifier, and the embodiment of the present application is not limited thereto.

Wherein the fifth information may be used to inform the fingerprint recognizer to hop frequencies or to reduce the working signal strength of the fingerprint recognizer. The fifth message may also be a notification to the fingerprint identifier, and the interference of the fingerprint identifier to the touch screen also satisfies a preset condition, so that the fingerprint identifier determines frequency hopping or reduces the working signal strength.

And S205, the processor sends fifth information to the fingerprint recognizer.

Other contents of the embodiments of the present application may refer to related contents of the other embodiments described above, and are not repeated.

Considering that the fingerprint recognizer and the touch screen are both in working states, and when the fingerprint recognizer and the touch screen are touched simultaneously, mutual interference exists between the fingerprint recognizer and the touch screen. In addition, in the actual use process of the terminal by the user, the time spent in the process from the time when the fingerprint identifier is awakened to the time when the fingerprint identifier is dormant is short. Therefore, the terminal can also start the frequency hopping of the touch screen or the working mode for improving the working signal intensity after the fingerprint recognizer detects the touch operation. Subsequently, if the fingerprint identifier is detected to be in a dormant state or the terminal is detected to be in a screen-off state, the frequency hopping of the touch screen is closed or the working mode of the working signal intensity is improved. Therefore, the frequency hopping of the terminal for starting the touch screen or the working time for improving the working signal intensity can be reduced, and the power consumption of the terminal is reduced.

Specifically, an embodiment of the present application further provides a method for operating a touch device, as shown in fig. 17, the method specifically includes steps S301 to S304, as follows:

s301, the fingerprint recognizer detects touch operation.

S302, the fingerprint recognizer informs the touch screen to start a frequency hopping or working mode for improving the working signal intensity.

For example: referring to fig. 16 (1), when the terminal is in a screen-off and screen-locking state, and the fingerprint identifier detects a touch operation of a user at time t2, the fingerprint identifier notifies the touch screen to start a working mode of frequency hopping or increasing the intensity of a working signal. Another example is: when the terminal is in an unlocking state, the fingerprint identifier detects the touch operation of a user at t5, and then the fingerprint identifier informs the touch screen to start a working mode of frequency hopping or improving the working signal intensity.

Another example is: referring to fig. 16 (2), when the terminal is in the screen lock state, and the fingerprint identifier detects a touch operation of the user at time t2, the fingerprint identifier notifies the touch screen to start a frequency hopping or working mode of increasing the working signal strength.

And S303, the touch screen starts a working mode of frequency hopping or improving the working signal intensity.

S304, if the touch screen detects that the interference signal meets the preset condition, the touch screen performs frequency hopping or improves the working signal intensity.

In some embodiments of the present application, if the fingerprint identifier does not detect the touch operation again within the preset time, the fingerprint identifier is dormant. In some embodiments of the present application, the fingerprint identifier notifies the touch screen to turn off the frequency hopping or increase the operating mode of the operating signal strength before, while, or after determining to sleep. In other embodiments of the present application, the touch screen may also actively acquire information whether the fingerprint identifier is dormant, and when it is determined that the fingerprint identifier is in a dormant state, the operating mode of frequency hopping or increasing the strength of the operating signal is turned off. The touch screen and the fingerprint recognizer can be in direct communication or can be in indirect communication through other hardware.

For example: referring to fig. 16 (1), the fingerprint recognizer is dormant at time t4, and the touch screen turns off the frequency hopping or working mode for increasing the working signal strength. For another example: the fingerprint recognizer is dormant at time t6, and the touch screen turns off the frequency hopping or working mode for increasing the working signal strength.

Another example is: referring to fig. 16 (2), the fingerprint recognizer is dormant at time t9, and the touch screen turns off the frequency hopping or working mode for increasing the working signal strength.

In further embodiments of the present application, if the terminal detects a screen locking operation of a user or detects that the terminal is off, the touch screen turns off the frequency hopping or improves the working mode of the working signal strength.

For example: referring to fig. 16 (2), the touch screen detects the screen being off at time t8, and the touch screen turns off the frequency hopping or the operation mode of increasing the intensity of the operation signal.

Step S304 may also be replaced with S304a-S304 b.

S304a, if the interference signal is detected to meet the preset condition, the touch screen sends sixth information to the fingerprint recognizer.

Wherein the sixth information may be used to inform the fingerprinter to hop frequencies or to reduce the working signal strength of the fingerprinter. The sixth message may also be a notification to the fingerprint identifier, and the interference of the fingerprint identifier to the touch screen also satisfies a preset condition, so that the fingerprint identifier determines frequency hopping or reduces the working signal strength.

S304b, the fingerprint recognizer hops or otherwise decreases the operating signal strength.

Other contents of the embodiment of the present application, for example, the fingerprint identifier notifies the touch screen to enter the frequency hopping mode or the working mode for increasing the working signal strength, and subsequent steps, refer to the related contents of the other embodiments described above, and are not repeated.

In some embodiments of the application, the terminal may also start a frequency hopping mode of the touch screen or an operating mode of increasing the intensity of the operating signal when the fingerprint identifier is in an operating state and the touch screen is bright. Subsequently, if the fingerprint identifier is detected to be in a dormant state or the terminal is detected to be in a screen-off state, the frequency hopping of the touch screen is closed or the working mode of the working signal intensity is improved. Therefore, the frequency hopping of the terminal for starting the touch screen or the working time for improving the working signal intensity can be reduced, and the power consumption of the terminal is reduced.

It is to be understood that step 301 may further include the fingerprint identifier determining that the touch screen is bright. Namely, the fingerprint recognizer detects touch and determines that the touch screen is bright, and informs the touch screen to start a working mode of frequency hopping or working signal intensity improvement.

Or the fingerprint identifier detects the touch operation, informs the touch screen to start the working mode of frequency hopping or working signal intensity improvement, and after receiving the notification of the fingerprint identifier, the touch screen determines that the touch screen is in a bright screen state, and then starts the working mode of frequency hopping or working signal intensity improvement. Specifically, an embodiment of the present application further provides a method for operating a touch device, as shown in fig. 18, the method specifically includes S301-S302, S303a, and S304, as follows:

and S303a, starting a working mode of frequency hopping or working signal strength improvement after the touch screen is lightened.

And the touch screen detects whether the touch screen is in a bright screen state after receiving the notification, and determines whether to start a frequency hopping or working mode for improving the working signal intensity.

For example: referring to fig. 16 (1), at time t3, the touch screen is unlocked and the touch screen determines to turn on the frequency hopping or the operation mode of increasing the intensity of the operation signal.

Another example is: referring to (2) of fig. 16, at time t7, the touch screen is unlocked and the touch screen determines to turn on the operation mode of frequency hopping or increasing the intensity of the operation signal.

The above description is only an embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions within the technical scope of the present disclosure should be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
