Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a working method and a terminal of a touch control device. Background Art

[0002] With the continuous development of communication technology, terminals have various touch-enabled modules that can provide human-computer interaction functions. In addition, as terminal layouts become more compact and chip sizes further decrease, electromagnetic interference (EMI) between module components becomes more prominent.

[0003] For example, the module components included in the terminal usually include a touch screen (Touch Panel, TP) that can detect the touch position, a fingerprint reader that can identify fingerprint patterns, etc. Among them, the touch screen can use capacitive or pressure recognition technology, and the fingerprint reader can use optical imaging, ultrasonic reflection, semiconductor capacitance change and other recognition technologies. Usually, the operating frequency of the touch screen is a frequency between 100kHz-400kHz, and the operating frequency of the fingerprint reader is a frequency between 200-350kHz. When the operating frequencies of the two module components are similar, due to the frequency tolerance problem of the module components during mass production, and the actual operating frequency of the module components will fluctuate up and down with the change of temperature. Therefore, it is very likely that the actual operating frequencies of the two module components will overlap. Then when the user operates the two module components at the same time, there will be mutual interference, and there will be problems such as no touch response, dial linkage, screen jumping, fingerprint unlocking failure, etc., which seriously affect the user experience. Summary of the invention

[0004] The present application provides a working method of a touch device and a terminal, which can reduce interference between different module components in the terminal and improve the user experience of the terminal.

[0005] In a first aspect, an embodiment of the present application provides a working method of a touch control device, which is applied to a terminal including a fingerprint identifier and a touch screen, wherein the touch screen includes a touch sensor and a display screen, and the method includes:

[0006] The fingerprint reader detects the user's touch operation; the fingerprint reader determines the working mode of the fingerprint reader according to the user's touch operation; if the working mode of the fingerprint reader is the preset working mode, the touch screen turns on the frequency hopping or improves the working signal strength working mode; if the touch screen detects that the interference signal meets the preset conditions, the touch sensor in the touch screen jumps the frequency or increases the working signal strength.

[0007] It can be seen that in the solution provided by the embodiment of the present application, when it is determined that the fingerprint reader is in the preset working mode, the touch screen starts the working mode of frequency hopping or increasing the working signal strength. Then, after determining that the detected interference signal meets the preset conditions, the touch sensor of the touch screen hops the frequency or increases the working signal strength, thereby reducing the interference between the fingerprint reader and the touch screen.

[0008] In one possible implementation, the preset working modes include: a fingerprint identifier being in a legal unlocking working mode, or a fingerprint identifier being in a working mode in which the terminal is unlocked; wherein, the fingerprint identifier being in a legal unlocking working mode means that the terminal is in a locked screen state, the fingerprint identifier collects the user's fingerprint, and the user's fingerprint verification is successful, and the fingerprint identifier notifies the terminal to unlock the working mode; wherein, the fingerprint identifier being in a terminal unlocking state working mode means that the terminal is in an unlocked state, and the fingerprint identifier detects a user's click, double-click, long press, or sliding operation.

[0009] It should be noted that when the fingerprint reader is in a legal unlocking mode or in a terminal unlocking mode, it can be considered that both the fingerprint reader and the touch screen are in working state. At this time, if the user notifies to touch the fingerprint reader and the touch screen, it may cause mutual interference between the two modules. Therefore, the touch screen needs to start frequency hopping or increase the working signal strength to reduce the mutual interference between the two modules and avoid abnormalities in the terminal.

[0010] Furthermore, in the embodiment of the present application, when either the touch screen or the fingerprint reader is in a non-working state (including a dormant state, a closed state, etc.) or both are in a non-working state, the terminal can turn off (or turn off) the working mode of frequency hopping or improving the working signal strength. For example: when the fingerprint reader is in a dormant state, it can be considered that the fingerprint reader is in a non-working state, and at this time the touch screen does not turn on (or turn off) the working mode of frequency hopping or improving the working signal strength. For another example: when the touch screen is in a screen-off state or a screen-locked state, it can be considered that the touch screen is in a non-working state, and at this time the touch screen does not turn on (or turn off) the working mode of frequency hopping or improving the working signal strength. It can be seen that the embodiment of the present application reduces the time for the touch screen to turn on the working mode of frequency hopping or improving the working signal strength, and reduces the time for the touch screen to periodically query the results of the interference signal and determine whether the interference signal meets the preset conditions, which is beneficial to saving the power consumption of the terminal and improving the response speed of the touch screen.

[0011] In one possible implementation, the preset condition is that the frequency of the interference signal is the sensitive frequency of the touch sensor in the touch screen, and the strength of the interference signal reaches a threshold; wherein the sensitive frequency of the touch sensor is a frequency between m and n times the fundamental frequency or odd harmonics of the touch sensor working signal, wherein m is greater than 0 and less than 1, and n is greater than 1 and less than 2.

[0012] It should be noted that the interference signal needs to meet preset conditions to cause the touch screen to work abnormally. The preset conditions include that the frequency of the interference signal is within the sensitive frequency interval of the touch screen operating frequency (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 within the sensitive interval of the touch screen operating frequency, which will affect the operation of the touch screen. The intensity of the interference signal reaches a certain threshold, which will cause the touch screen to work abnormally.

[0013] The sensitive frequency range of the touch screen is a range near the fundamental frequency or odd harmonics of the touch screen working signal, for example, it may be between 0.9 times and 1.1 times the touch screen working frequency.

[0014] In a possible implementation, if the working mode of the fingerprint identifier is a preset working mode, the touch screen starts a working mode of frequency hopping or increasing the working signal strength, specifically:

[0015] 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 to notify the touch screen to turn on the frequency hopping or increase the working signal strength working mode; the touch screen turns on the frequency hopping or increases the working signal strength working mode.

[0016] In a possible implementation, the fingerprint identifier sends the first information to the touch screen, and the first information is used to notify the touch screen to start the frequency hopping or improve the working signal strength. Specifically, the working mode is:

[0017] The fingerprint identifier sends first information to the touch screen through the processor, and the first information is used to notify the touch screen to start a working mode of frequency hopping or improving the working signal strength.

[0018] Among them, the processor can specifically be an application processor, or a chip-level system (System on Chip, SOC). The processor here can also be other hardware that has communication connections with the touch screen and the fingerprint reader respectively, which is not limited in the embodiments of the present application.

[0019] In a possible implementation, if the working mode of the fingerprint identifier is a preset working mode, the touch screen starts a working mode of frequency hopping or increasing the working signal strength, which is also specifically:

[0020] The fingerprint identifier sends second information to the processor, and the second information includes the working mode of the fingerprint identifier; the processor determines that the working mode of the fingerprint identifier is a preset working mode based on the second information, and sends third information to the touch screen, and the third information is used to notify the touch screen to turn on the frequency hopping or increase the working signal strength working mode; the touch screen turns on the frequency hopping or increases the working signal strength working mode.

[0021] In a possible implementation, if the working mode of the fingerprint identifier is a preset working mode, the touch screen starts a working mode of frequency hopping or increasing the working signal strength, which is also specifically:

[0022] The fingerprint identifier sends fourth information to the touch screen, the fourth information including the working mode of the fingerprint identifier; the touch screen determines that the working mode of the fingerprint identifier is the preset working mode according to the fourth information; the touch screen turns on the working mode of frequency hopping or improving the working signal strength.

[0023] In a possible implementation, the fingerprint identifier sends fourth information to the touch screen, where the fourth information includes a working mode of the fingerprint identifier, specifically:

[0026] In a possible implementation, if the working mode of the fingerprint identifier is a preset working mode, the touch screen starts a working mode of frequency hopping or increasing the working signal strength, which is also specifically:

[0027] If the working mode of the fingerprint identifier is the preset working mode, the touch screen starts to detect interference signals and turns on the working mode of frequency hopping or increasing the working signal strength.

[0028] It should be noted that the touch screen can start detecting interference signals when the terminal is turned on, or when the terminal is in the screen-on state. The touch screen can also start detecting interference signals after receiving the first information sent by the fingerprint identifier to the touch screen. Specifically, the fingerprint identifier can determine that the fingerprint identifier is in a legal unlocking working mode or any working mode in the unlocked state of the touch screen based on its own working mode, and then notify the touch screen to start detecting interference signals. The fingerprint identifier can also send its own working mode to the touch screen, and the touch screen determines whether to turn on the detection of interference signals. If it is determined that the fingerprint identifier is in a legal unlocking working mode or any working mode in the unlocked state, the touch screen starts detecting interference signals. In this way, the time for the touch screen to detect interference signals is relatively short, which is conducive to further reducing the power consumption of the terminal.

[0029] It should also be noted that the second module can simultaneously start the working mode of detecting interference signals and starting frequency hopping or increasing the strength of the working signal. It can also start the working mode of detecting interference signals first and then starting frequency hopping or increasing the strength of the working signal.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0087] In order to better understand the technical solutions provided by the embodiments of the present application, some professional terms involved in the embodiments of the present application are first explained.

[0089] Electromagnetic interference: refers to the interference phenomenon caused by the interaction of electromagnetic waves with electronic components. There are two types of interference: conducted interference and radiated interference. Conducted interference refers to the coupling (interference) of a signal on an electrical network to another electrical network through a conductive medium. Radiated interference refers to the coupling (interference) of an interference source's signal to another electrical network through space. In the embodiment of the present application, the electromagnetic waves of one module component when it is working are conducted to another module component, thereby interfering with the normal operation of the other module component.

In some embodiments, at least some of the functional modules of the RF module 150 can be set in the processor 150. In other embodiments, at least some of the functional modules of the RF module 150 can be set in the same device as at least some of the modules of the processor 110.

[0108] The modem processor may include a modulator and a demodulator. The modulator is used to modulate the low-frequency baseband signal to be sent into a medium-high frequency signal. The demodulator is used to demodulate the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After the low-frequency baseband signal is processed by the baseband processor, it is passed to the application processor. The application processor outputs a sound signal through an audio device (not limited to a speaker, a receiver, etc.), or displays an image or video through a display screen. In some embodiments, the modem processor may be an independent device. In other embodiments, the modem processor may be independent of the processor and be set in the same device as the RF module or other functional modules.

[0113] The terminal 100 can realize the shooting function through the ISP, the camera 193, the video codec, the GPU, the display screen and the application processor.

[0114] The ISP is used to process the data fed back by the camera. For example, when taking a photo, the shutter is opened, and the light is transmitted to the camera photosensitive element through the lens. The light signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to the ISP for processing and converts it into an image visible to the naked eye. The ISP can also perform algorithm optimization on the noise, brightness, and skin color of the image. The ISP can also optimize the exposure, color temperature and other parameters of the shooting scene. In some embodiments, the ISP can be set in the camera 193.

[0115] Camera 193 is used to capture still images or videos. The object generates an optical image through the lens and projects it onto the photosensitive element. The photosensitive element can be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, and then passes the electrical signal to the ISP to be converted into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV or other format. In some embodiments, the terminal 100 may include 1 or N cameras, where N is a positive integer greater than 1.

Through NPU, applications such as intelligent cognition of the terminal 100 can be realized, such as image recognition, face recognition, voice recognition, text understanding, etc.

[0119] The external memory interface 120 can be used to connect an external memory card, such as a Micro SD card, to expand the storage capacity of the terminal 100. The external memory card communicates with the processor through the external memory interface to implement a data storage function, such as storing music, video and other files in the external memory card.

[0120] The internal memory 121 can be used to store computer executable program codes, which include instructions.

[0121] The terminal 100 can implement audio functions such as music playing and recording through the audio module 170, the speaker 170A, the receiver 170B, the microphone 170C, the earphone interface 170D, and the application processor.

[0122] The audio module 170 is used to convert digital audio information into analog audio signal output, and is also used to convert analog audio input into digital audio signals. The audio module can also be used to encode and decode audio signals. In some embodiments, the audio module can be arranged in the processor 110, or some functional modules of the audio module can be arranged in the processor 110.

[0123] The speaker 170A, also called a "speaker", is used to convert an audio electrical signal into a sound signal. The terminal 100 can listen to music or listen to a hands-free call through the speaker.

[0124] The receiver 170B, also called a "handset", is used to convert audio electrical signals into sound signals. When the terminal 100 receives a call or voice message, the voice can be received by placing the receiver close to the ear.

[0125] Microphone 170C, also called "microphone" or "microphone", is used to convert sound signals into electrical signals. When making a call or sending a voice message, the user can make a sound by putting his mouth close to the microphone to input the sound signal into the microphone. The terminal 100 can be provided with at least one microphone. In some embodiments, the terminal 100 can be provided with two microphones, which can not only collect sound signals but also realize noise reduction function. In some embodiments, the terminal 100 can also be provided with three, four or more microphones to realize the collection of sound signals, noise reduction, identification of sound sources, realization of directional recording function, etc.

[0126] The earphone interface 170D is used to connect a wired earphone, and the earphone interface may be a USB interface, or a 3.5 mm open mobile terminal platform (OMTP) standard interface, or a cellular telecommunications industry association of the USA (CTIA) standard interface.

[0127] The fingerprint sensor 180H is used to collect fingerprints. The terminal 100 can use the collected fingerprint characteristics to achieve fingerprint unlocking, access application locks, fingerprint photography, fingerprint call answering, etc. The fingerprint sensor 180H is the main component of the fingerprint identifier.

[0128] In some embodiments of the present application, a fingerprint reader may be configured on the back of the terminal 100 (e.g., below the rear camera), or on the front of the terminal 100 (e.g., below the display screen 194). For another example, a fingerprint reader may be configured in the display screen 194 to implement the fingerprint recognition function, that is, the fingerprint reader may be integrated with the display screen 194 to implement the fingerprint recognition function of the terminal 100. In this case, the fingerprint reader is configured in the display screen 194, may be a part of the display screen 194, or may be configured in the display screen 194 in other ways. The fingerprint reader in the embodiments of the present application may use any type of sensing technology, including but not limited to optical, capacitive, piezoelectric or ultrasonic sensing technology.

[0129] Taking the fingerprint identifier as a capacitive fingerprint sensor as an example, similarly, the structure of the fingerprint identifier can be similar to the structure of the touch device in the touch screen, but smaller in size. The fingerprint identifier is used to detect the fingerprint pattern. Since the fingerprint pattern of the hand is uneven, the actual distance between the convex point and the concave point in contact with the flat plate is different, and the capacitance / inductance values ​​formed are also different. The fingerprint identifier can thus detect the fingerprint pattern. The fingerprint identifier outputs a touch signal, and according to this principle, the different capacitance detection values ​​collected are summarized and sent to the processor 110 to complete the fingerprint collection. It is also possible to compare the detected pattern to determine whether it is the same as one of the one or more pre-stored fingerprint patterns to perform fingerprint verification and then perform other interactive actions.

[0130] The touch sensor 180K, also known as a "touch panel", can be disposed on a display screen and used to detect a touch operation applied thereto or near the touch sensor. The detected touch operation can be transmitted to an application processor to determine the type of touch event and provide a corresponding visual output through the display screen.

[0131] In some embodiments of the present application, the touch sensor 180K can also form a touch screen of the terminal 100 together with the display screen 194. Among them, the touch sensor 180K can collect touch events of the user of the terminal 100 on or near it (such as the user using any suitable object such as a finger, a stylus, etc. on the touch sensor 180K or near the touch sensor 180K), and send the collected touch information to other devices (such as the processor 110). Among them, the touch event of the user near the touch sensor 180K can be called a floating touch; floating touch can mean that the user does not need to directly contact the touch sensor 180K in order to select, move or drag a target (such as an icon, etc.), but only needs the user to be near the device to perform the desired function. In addition, the touch sensor 180K can be implemented by various types such as resistive, capacitive, infrared and surface acoustic waves. Taking a capacitive touch screen as an example, a capacitive touch screen includes an insulator covered with a transparent conductor formed on a specific layout. When a finger or other object touches the surface of the touch screen, the capacitance changes, and the processor 110 can determine the position of the touch by detecting the change in capacitance.

[0132] The key 190 includes a power key, a volume key, etc. The key may be a mechanical key or a touch key. The terminal 100 receives the key input and generates a key signal input related to the user settings and function control of the terminal 100.

[0133] Motor 191 can generate vibration prompts. The motor can be used for incoming call vibration prompts, and can also be used for touch vibration feedback. For example, touch operations acting on different applications (such as taking pictures, audio playback, etc.) can correspond to different vibration feedback effects. Touch operations acting on different areas of the display screen can also correspond to different vibration feedback effects. Different application scenarios (for example: time reminders, receiving messages, alarm clocks, games, etc.) can also correspond to different vibration feedback effects. The touch vibration feedback effect can also support customization.

[0134] Indicator 192 may be an indicator light, which may be used to indicate charging status, power changes, messages, missed calls, notifications, etc.

[0135] The SIM card interface 195 is used to connect a subscriber identity module (SIM). The SIM card can be connected to or disconnected from the terminal 100 by inserting into or removing from the SIM card interface.

[0136] The software system of the terminal 100 may adopt a layered architecture, an event-driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. The embodiment of the present application takes the Android system of the layered architecture as an example to exemplify the software structure of the terminal 100.

[0137] The layered architecture divides the software into several layers, each with clear roles and division of labor. The layers communicate with each other through interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom: the application layer, the application framework layer, the Android runtime and system library, and the kernel layer.

[0138] The application layer can include a series of application packages.

[0139] like Figure 2 As shown, the application package may include camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message and other applications.

[0140] The application framework layer provides an application programming interface (API) and a programming framework for the applications in the application layer. The application framework layer includes some predefined functions.

[0141] like Figure 2 As shown, the application framework layer may include a window manager, a content provider, a view system, a phone manager, a resource manager, a notification manager, and the like.

[0142] The window manager is used to manage window programs. The window manager can obtain the display screen size, determine whether there is a status bar, lock the screen, capture the screen, etc.

[0143] Content providers are used to store and retrieve data and make it accessible to applications. The data may include videos, images, audio, calls made and received, browsing history and bookmarks, phone books, etc.

[0144] The view system includes visual controls, such as controls for displaying text, controls for displaying images, etc. The view system can be used to build applications. A display interface can be composed of one or more views. For example, a display interface including a text notification icon can include a view for displaying text and a view for displaying images.

[0145] The phone manager is used to provide communication functions of the terminal 100, such as management of call status (including connection, disconnection, etc.).

[0146] The resource manager provides various resources for applications, such as localized strings, icons, images, layout files, video files, and so on.

[0147] The notification manager enables applications to display notification information in the status bar. It can be used to convey notification-type messages and can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify download completion, message reminders, etc. The notification manager can also be a notification that appears in the system top status bar in the form of a chart or scroll bar text, such as notifications of applications running in the background, or a notification that appears on the screen in the form of a dialog window. For example, a text message is displayed in the status bar, a prompt sound is emitted, the terminal vibrates, the indicator light flashes, etc.

[0148] Android Runtime includes core libraries and virtual machines. Android runtime is responsible for scheduling and management of the Android system.

[0149] The core library consists of two parts: one part is the function that needs to be called by the Java language, and the other part is the Android core library.

[0150] The application layer and the application framework layer run in a virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

[0151] The system library can include multiple functional modules, such as surface manager, media libraries, OpenGL ES, SGL, etc.

[0152] Among them, the surface manager is used to manage the display subsystem and provide the fusion of 2D and 3D layers for multiple applications.

[0153] The media library supports playback and recording of a variety of commonly used audio and video formats, as well as static image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0154] OpenGL ES is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

[0155] SGL is a graphics engine for 2D graphics.

[0156] The kernel layer is the layer between hardware and software. The kernel layer contains at least display driver, camera driver, audio driver, and sensor driver.

[0157] like Figure 4 , which is a schematic diagram of the appearance of the terminal 100. The terminal 100 includes a touch screen 401 and a fingerprint identifier 402. A graphical user interface is displayed on the touch screen 401. For example Figure 4 In addition, the visible components of the terminal 100 include any one or a combination of the following: a speaker, a microphone, various interfaces such as a charging interface / earphone, various physical buttons such as a volume button / lock screen button, a camera, a flash, and other structures.

[0158] In some embodiments, Figure 4 As shown, the touch screen 401 and the fingerprint identifier 402 may be located in two areas on the same side of the terminal 100. In other embodiments, the touch screen 401 and the fingerprint identifier 402 may also be located on two opposite sides of the terminal 100, for example, the touch screen 401 is on the front side and the fingerprint identifier 402 is on the back side. In still other embodiments, the touch screen 401 and the fingerprint identifier 402 may also be located in the same area, which will not be described in detail.

[0159] The following is an illustrative description of the software and hardware workflow of the terminal 100 in conjunction with a specific scenario of the embodiment of the present application.

[0160] In some embodiments of the present application, after the fingerprint identifier detects a touch operation, the fingerprint identifier collects the user's fingerprint information, and the fingerprint identifier compares the collected fingerprint information with the pre-stored legal fingerprint information. 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 locked screen state, the application unlocks the screen. And calls the display driver in the kernel layer to display the interface after the terminal is unlocked through the touch screen.

[0161] At the same time, before, or after the fingerprint reader reports the comparison result to the corresponding application in the application layer through the kernel layer, the fingerprint reader sends its own legal unlocking working mode to the touch screen so that the touch screen can determine whether to turn on the working mode of frequency hopping or improving the working signal strength. The specific operation and interaction of the fingerprint reader and the touch screen can be referred to in detail below.

[0162] In some 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 can be triggered to report a touch event (such as touch point position, time and other parameters) generated by the user's touch action to the kernel layer through a corresponding driver, and the kernel layer encapsulates the touch event and calls a corresponding API to distribute the touch event to an application in the application layer. The application in the application layer performs different operations according to different touch operations, and calls a display driver in the kernel layer to display a corresponding interface through the touch screen.

[0163] At the same time, before, or after the fingerprint reader reports the touch event generated by the user's touch action to the kernel layer through the corresponding driver, the fingerprint reader sends the unlocked working mode to the touch screen so that the touch screen can determine whether to turn on the frequency hopping or improve the working signal strength. The specific operation and interaction of the fingerprint reader and the touch screen can be found in detail below.

[0164] The methods in the following embodiments can all be implemented in the terminal 100 having the above hardware structure and software structure.

[0165] Considering that the touch screen and the fingerprint reader are two module components that are used most frequently by users, the following takes the interference between the touch screen and the fingerprint reader as an example to briefly explain the principle of interference between module components.

[0166] When the touch screen and the fingerprint reader are both in working state, when the user's finger 1 touches the fingerprint reader and the finger 2 also touches the touch screen at the same time, the user's body, the terminal and the earth (PE) form a Figure 3 The circuit diagram shown.

[0167] When the finger 1 touches the fingerprint recognition device (hereinafter referred to as the "fingerprint device"), the surface of the finger 1 forms a capacitor C with the surface of the fingerprint recognition device. f Similarly, when finger 2 touches the touch screen, the surface of finger 2 forms a capacitor C with the surface of the touch screen. t The human body resistance between finger 1 and finger 2 is R2. The equivalent capacitance of the touch screen self-capacitance to the terminal ground (GND) is C tpi Obviously, the human body resistance R2 and capacitance C f , capacitor C t and Ctpi A closed path is formed, which is the interference path. That is to say, at this time, the electromagnetic waves of the fingerprint reader when working will be transmitted to the touch screen through the closed path. If the working frequency of the fingerprint reader and the working frequency of the touch screen coincide at this time, the working signal of the fingerprint reader will interfere with the touch screen. In other words, from the perspective of the touch screen, the working signal of the fingerprint reader at this time can be regarded as an interference signal of the touch screen. When the working signal strength of the fingerprint reader reaches a certain threshold, it will cause the touch screen to work abnormally. For example: there will be no response to touch on the touch screen, dial linkage, screen jumping, etc.

[0168] Similarly, the electromagnetic waves when the touch screen is working will also be transmitted to the fingerprint reader through this closed path. If the working frequency of the fingerprint reader coincides with the working frequency of the touch screen, the working signal of the touch screen will interfere with the fingerprint reader. In other words, from the perspective of the fingerprint reader, the working signal of the touch screen at this time can be regarded as an interference signal of the fingerprint reader. When the working signal strength of the touch screen reaches a certain threshold, the fingerprint reader will work abnormally. For example: fingerprint unlocking fails, or there is no response when touching the fingerprint reader.

[0169] Here, the fingerprint identifier interfering with the touch screen is taken as an example to exemplify the method for reducing the interference of the fingerprint identifier on the touch screen.

[0170] First, in order to better understand the interference of the fingerprint reader on the touch screen, the interference signal caused by the fingerprint reader is quantified. Figure 3 As shown, the fingerprint identifier can calculate the interference voltage V of the fingerprint identifier on the touch screen according to the existing calculation method. f .

[0171]

[0172] Among them, C m The capacitance of the human body to the earth is about 100 picofarads (pF). s is the capacitance of the terminal to the ground, which is about 10pF. h The capacitance between the human body and the mobile phone is usually greater than 1pF. f is the capacitance of the finger to the fingerprint reader. C t is the capacitance of the finger to the touch screen, usually 5pF. R1 is the resistance of the human body, usually between 330 and 2000 ohms. R2 and R3 are the resistances inside the human body, both about 5000 ohms. tpi It is the equivalent capacitance of the touch screen self-capacitance to the terminal ground, usually less than 1pF. V1 is the operating voltage of the fingerprint reader.

[0173] Since the operating frequency of the fingerprint reader and touch screen is between 50 kHz and 1 MHz, R1, R2, R3 and C m can be ignored. Also, due to the capacitance C of the touch screen tp =C t C tpi / (C t +C tpi ). Then, the interference voltage V caused by the fingerprint reader to the touch screen f It can be written as follows:

[0174]

[0175] As can be seen from the above formula, the voltage strength of the interference signal is positively correlated with the working voltage of the fingerprint reader. The voltage strength of the interference signal is also related to the capacitance formed by the user's finger touching the fingerprint reader and the fingerprint reader. The voltage strength of the interference signal is also related to the capacitance formed by the user's finger touching the touch screen and the touch screen, which will not be repeated one by one.

[0176] It should be noted that the interference signal needs to meet preset conditions to cause the touch screen to work abnormally. The preset conditions include that the frequency of the interference signal is within the sensitive frequency interval of the touch screen operating frequency (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 within the sensitive interval of the touch screen operating frequency, which will affect the operation of the touch screen. The intensity of the interference signal reaches a certain threshold, which will cause the touch screen to work abnormally.

[0177] The sensitive frequency range of the touch screen is a range near the fundamental frequency or odd harmonics of the touch screen working signal, for example, it may be between 0.9 times and 1.1 times the touch screen working frequency.

[0178] To this end, the touch screen can detect interference signals, and when it is detected that the interference signals meet preset conditions, a corresponding method of reducing the interference is adopted.

[0179] In some embodiments of the present application, when the touch screen detects that the interference signal meets the preset conditions, the fingerprint identifier can be reduced by frequency hopping. This is because when the touch screen detects that the interference signal meets the preset conditions, the current operating frequency of the touch screen is close to the frequency of the interference signal, so the touch screen can hop, that is, the touch screen switches the current operating frequency to another frequency, and the switched operating frequency may not overlap with the interference frequency, thereby avoiding mutual interference between the two module components.

[0180] In other embodiments of the present application, when the touch screen detects that the interference signal meets the preset conditions, the fingerprint identifier can be reduced from interfering with the touch screen by increasing the strength of the working signal. This is because after the touch screen increases the strength of its own working signal, the strength of the interference signal is not enough to cause the touch screen to work abnormally, which is equivalent to the touch screen reducing the interference of the fingerprint identifier.

[0181] In some other embodiments of the present application, when it is detected that the interference signal meets the preset conditions, the fingerprint identifier can also reduce its interference to the touch screen by frequency hopping or reducing the strength of the working signal. Similarly, the frequency hopping of the fingerprint identifier can make the working frequency of the touch screen and the working frequency of the fingerprint identifier not overlap, thereby avoiding mutual interference between the two module components. In addition, according to the voltage formula of the above-mentioned interference signal, it can be seen that after the fingerprint identifier reduces the strength of the working signal, the strength of the interference signal is reduced, and the interference effect is not enough to cause abnormal operation of the touch screen.

[0182] The working signal of the touch screen is a working signal for detecting touch, and the working signal of the fingerprint reader is a working signal for detecting touch.

[0183] It should be noted that the touch screen usually includes a touch layer and a display screen. The main component of the touch layer is the touch sensor. In the embodiment of the present application, the touch screen is mainly interfered with by the touch sensor of the touch layer. Therefore, when the touch screen adopts the frequency hopping method to reduce the interference of the fingerprint identifier, it is mainly the touch sensor of the touch layer that hops, so that the working frequency of the touch sensor does not overlap with the working frequency of the fingerprint identifier. When the touch screen adopts the method of increasing the working signal strength to reduce the interference of the fingerprint identifier, it also mainly refers to increasing the strength of the working signal of the touch sensor of the touch screen. Similarly, when the fingerprint identifier frequency hopping is used to reduce the interference to the touch screen, it is also mainly to make the working frequency of the fingerprint identifier and the touch sensor of the touch layer not overlap. 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 will not be repeated below.

[0184] Considering that if the terminal is in the power-on state and the touch screen is in the bright screen state, the touch screen has been turning on the working mode of frequency hopping or increasing the working signal strength, the touch screen will periodically judge whether the interference signal detected by the touch screen meets the preset conditions. When the preset conditions are met, the touch screen hops or increases the working signal strength. In this working mode, the touch screen periodically judges whether the interference signal meets the preset conditions, and the power consumption is large. Therefore, in the technical solution provided in the embodiment of the present application, the touch screen can only turn on the working mode of frequency hopping or increasing the working signal strength of the touch screen when both the fingerprint identifier and the touch screen are in the working state, that is, the touch screen can only periodically judge whether the interference signal detected by the touch screen meets the preset conditions when both the fingerprint identifier and the touch screen are in the working state. After the preset conditions are met, the touch screen hops or increases the working signal strength. Usually, since the touch screen is in a working state and the fingerprint identifier is also in a working state, and the time is not long, the method provided in the embodiment of the present application can greatly reduce the power consumption of the terminal.

[0185] When both the fingerprint reader and the touch screen are in working state and are touched at the same time, the above interference will occur. Therefore, the following briefly introduces the situation involving both the fingerprint reader and the touch screen in working state in combination with the working process of the fingerprint reader in the terminal.

[0186] like Fig.16 (1) is a timing diagram of the working process of the fingerprint recognition device and the touch screen in the terminal. The details are as follows:

[0187] During the time period from time t1 to time t2, the terminal is in sleep mode, and the screen of the terminal is off. At this time, the fingerprint reader and the touch screen are also in sleep mode.

[0188] At time t2, the terminal detects the user's touch operation on the fingerprint identifier and wakes up the fingerprint identifier. The fingerprint identifier reads the user's fingerprint information and compares it with the pre-stored fingerprint. If the comparison fails, the terminal continues to be in the locked screen state; in some embodiments of the present application, if the comparison fails, the terminal can continue to keep the screen off. At this time, the fingerprint identifier is in working state and the touch screen is still in dormant state. In other embodiments of the present application, if the comparison fails, the terminal can light up the screen, and the screen displays the lock screen interface. Fig.16As shown in (2), after the terminal detects the user's touch operation on the fingerprint recognition device at time t2, the fingerprint sensor is in working state, and the terminal lights up the screen at time t7. During the time period from time t7 to time t8 (the terminal turns off the screen at time t8), both the fingerprint recognition device and the touch screen are in working state. It is understandable that the user can perform limited operations on the lock screen interface at this time, so it is also possible to ignore the situation where the touch screen is in working state at this time. After a certain period of time, that is, at time t8, the terminal turns off the screen. From time t8 to time t9, the fingerprint recognition device is in working state and the touch screen is in non-working state. It is understandable that the fingerprint recognition device may also go into sleep state before the terminal turns off the screen.

[0189] If the match is successful, the terminal is unlocked (t3), at which point the touch screen is awakened and displays the main interface or other interfaces. The fingerprint reader is now in legal unlocking mode. At this point, the fingerprint reader is in working state, and the touch screen is also in working state. When the terminal is unlocked, if the user does not touch the fingerprint reader again within a period of time, the fingerprint reader enters the dormant state again at t4, and the touch screen is still in working state.

[0190] It is understandable that from the time when the terminal is successfully unlocked to the time when the fingerprint reader enters the dormant state again (i.e., the time period from time t3 to time t4), the fingerprint reader and the touch screen are both in working state. If during this period, the terminal detects that the user touches the fingerprint reader and the touch screen at the same time, the above-mentioned interference may occur.

[0191] Continuing, when the terminal is unlocked and the fingerprint reader is in sleep mode, if it detects that the user touches the fingerprint reader, the fingerprint reader is awakened. At this time, both the fingerprint reader and the touch screen are in working state. The user's touch operation of the fingerprint reader may be long press, double click, slide, etc. The fingerprint reader recognizes the specific operation gesture and executes the corresponding instruction.

[0192] It is understandable that when the terminal is in the unlocked state, after the fingerprint reader is touched at time t5, both the fingerprint reader and the touch screen are in the working state. If during this period (the period from time t5 to time t6), the terminal detects that the user touches the fingerprint reader and the touch screen at the same time, the above-mentioned interference may occur.

[0193] In view of the mutual interference between the fingerprint reader and the touch screen, an embodiment of the present application provides a method for operating a touch device, which can enable the touch screen to start frequency hopping or increase the working signal strength when both the fingerprint reader and the touch screen are in working state.

[0194] like Figure 5As shown, a schematic diagram of a flow chart of a touch device working method is provided in an embodiment of the present application. The method includes: S101-S105, which are specifically as follows:

[0195] S101, the first module is in a dormant state.

[0196] The first module assembly is a module assembly that interferes with the second module assembly. For example, the first module assembly may be a fingerprint identifier, and the second module assembly may be a touch screen.

[0197] S102: The first module detects a touch operation, and the first module is awakened.

[0198] Exemplarily, the first module is a fingerprint reader. Then, after detecting the user's touch operation on the fingerprint reader, the fingerprint reader is awakened and starts working. For example: the fingerprint reader starts to detect the texture of the user's fingerprint and compares it with the pre-stored fingerprint; identifies the operation gesture of the touch operation, such as: long press, click, double click, slide, etc.; and determines different operations according to different operation gestures.

[0199] S103: The first module assembly sends first information to the second module assembly.

[0200] In some embodiments of the present application, Figure 6 As shown, the first information may be the working mode of the first module component. That is, the first module component directly sends its own working mode to the second module component, and the second module component determines whether to turn on the frequency hopping or the working mode of improving the working signal strength. After determining that the second module component needs to turn on the frequency hopping or the working mode of improving the working signal strength ( Figure 6 After that, the second module starts the working mode of frequency hopping or increasing the working signal strength.

[0201] Taking the first module component as a fingerprint identifier and the second module component as a touch screen as an example, the first information can specifically be that the fingerprint identifier is in a legal unlocking working mode, and the fingerprint identifier is in a long press, click, double click, or sliding working mode when the touch screen is unlocked. Specifically, the processor will inform the fingerprint identifier in advance whether the terminal is currently in a locked screen state or an unlocked state. After detecting the touch operation, the fingerprint identifier will determine the working mode of the fingerprint identifier itself according to whether the terminal is currently in a locked screen state or an unlocked state. For example: if the terminal is in a locked screen state, the fingerprint identifier will collect the user's fingerprint information after detecting the touch operation, and compare the collected fingerprint information with the pre-stored legal fingerprint information. If the comparison is successful, the fingerprint identifier will report it to the processor. The processor unlocks the terminal screen. Then, the fingerprint identifier can be determined to work in a legal unlocking working mode. For another example: if the terminal is in an unlocked state, then after the fingerprint identifier detects the touch operation, the fingerprint identifier will report the touch event (including touch coordinates, timestamp of the touch operation, etc.) to the processor, and the processor performs different operations according to different touch events. Then, the fingerprint reader can determine whether it is working in the unlocked state in long press, click, double click, or sliding working modes.

[0202] Then, the second module component determines whether the second module component needs to start the frequency hopping or improve the working signal strength working mode according to the working mode of the first module component.

[0203] In other embodiments of the present application, Figure 7 As shown, the first information can be used to notify the second module component to start the frequency hopping or improve the working signal strength of the second module component. That is, after detecting the touch operation, the first module component first determines whether the second module component needs to start the frequency hopping or improve the working signal strength working mode. After determining that the second module component needs to start the frequency hopping or improve the working signal strength working mode ( Figure 7 After that, the second module is notified to start the working mode of frequency or improve the working signal strength.

[0204] The first module component determines that the second module component needs to turn on the frequency or improve the working signal strength of the working mode, specifically including: the first module component first determines its own working mode, and further determines whether the first module component and the second module component are both in the working state. If the first module component and the second module component are both in the working state, the first module component determines that the second module component needs to turn on the frequency or improve the working signal strength of the working mode, so as to reduce the interference between the two module components.

[0205] Still taking the example that the first module component is a fingerprint identifier and the second module component is a touch screen, the fingerprint identifier determines its own working mode after being awakened. The specific method of determining the working mode can refer to the description above and will not be repeated here. When the fingerprint identifier determines that it is in a legal unlocking mode, or in any working mode in the unlocking state (long press, click, double click, or sliding working modes in the unlocking state), it can be determined that the touch screen is also in working state. Therefore, the fingerprint identifier can notify the touch screen to turn on the working mode of frequency hopping or increasing the working signal strength to reduce or reduce the interference between the two module components.

[0206] S104: The second module starts a frequency hopping or working mode to increase the working signal strength.

[0207] In some embodiments of the present application, the second module component receives the first information sent by the first module component, and the first information notifies the second module component to start the frequency hopping or improve the working signal strength working mode, then the second module component starts the frequency hopping or improves the working signal strength working mode.

[0208] In some 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 first determine whether to turn on the working mode of frequency hopping or improving the working signal strength. Then, step S104 is executed. The specific determination method of the second module is similar to the determination method of the first module in step S103c, which is not repeated here.

[0209] It should be noted that the second module component can start detecting interference signals before step S104. Take the first module component as a fingerprint device and the second module component as a touch screen as an example for explanation. Exemplarily, the touch screen can start detecting interference signals when the terminal is turned on, or when the terminal is in a bright screen state or an unlocked state. The touch screen can also start detecting interference signals in step S103, that is, after receiving the first information sent by the fingerprint identifier to the touch screen. Specifically, the fingerprint identifier can determine that the fingerprint identifier is in a legal unlocking working mode or any working mode in the unlocked state according to its own working mode, and notify the touch screen to start detecting interference signals. It can also be that the fingerprint identifier sends its own working mode to the touch screen, and the touch screen determines whether to turn on the detection of interference signals. If it is determined that the fingerprint identifier is in a legal unlocking working mode or any working mode in the unlocked state, the touch screen starts detecting interference signals. In this way, the time for the touch screen to detect interference signals is relatively short, which is conducive to further reducing the power consumption of the terminal. The embodiment of the present application does not limit this.

[0210] It should also be noted that the second module can simultaneously start the working mode of detecting interference signals and starting frequency hopping or increasing the strength of the working signal. It can also start the working mode of detecting interference signals first and then starting frequency hopping or increasing the strength of the working signal.

[0211] Continuing, after the second module component starts the working mode of frequency hopping or increasing the working signal strength, the second module component will query the detection result of the interference signal at regular intervals. If the second module component detects that the interference signal meets the preset condition, step S105 is executed. Otherwise, the second module component continues to query the detection result of the second module component for the interference signal at regular intervals.

[0212] Optionally, in some other embodiments of the present application, if the second module component detects that the interference signal does not meet the preset conditions within a preset time period, it can be considered that the first module component still does not interfere with the second module component for a period of time after the time period, or the interference does not affect the normal operation of the second module component. Therefore, the second module component can turn off the frequency hopping or increase the working signal strength. In this way, it is beneficial to save terminal power consumption and improve the response speed of the second module component.

[0213] Optionally, in some other embodiments of the present application, taking the first module component as a fingerprint identifier and the second module component as a touch screen as an example, if within a preset time period, the touch screen detects that the interference signal has not met the preset conditions and the fingerprint identifier has not detected the touch operation again, the touch screen can turn off the frequency hopping or increase the working signal strength working mode.

[0214] Optionally, in some other 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 obtains that the fingerprint identifier is in a dormant state or the touch screen detects the user's lock screen operation, the touch screen turns off the frequency hopping or increases the working signal strength. This is because the fingerprint identifier is in a dormant state, or the touch screen is in a lock screen state, which means that the fingerprint identifier and the touch screen are not in a working state at the same time, and there will be no mutual interference. Therefore, the touch screen turns off the frequency hopping or increases the working signal strength to reduce the power consumption of the terminal. Among them, the above-mentioned touch screen obtains that the fingerprint identifier is in a dormant state, which can be the fingerprint identifier sending the dormant state information to the touch screen, or the touch screen actively obtains the information that the fingerprint identifier is in a dormant state. This is not limited to the embodiments of the present application. The touch screen and the fingerprint identifier can communicate directly or indirectly through other hardware. Among them, the above-mentioned user's lock screen operation can be an operation such as the user clicking the lock screen button.

[0215] For example: See Fig.16In (1), when the terminal is in the locked screen state, the fingerprint reader is touched at time t2, collects the user's fingerprint information, verifies the legitimacy of the user's fingerprint information, and determines that it is working in the legal unlocking working mode at time t3. Then, the touch screen turns on the working mode of frequency hopping or increasing the working signal strength. When the fingerprint reader goes to sleep at time t4, the touch screen turns off the working mode of frequency hopping or increasing the working signal strength. In other words, the touch screen turns on the working mode of frequency hopping or increasing the working signal strength from time t3 to time t4.

[0216] For example: See Fig.16 In (1), when the terminal is in an unlocked state, the fingerprint identifier is touched at time t5, and the fingerprint identifier determines that it is in the working mode of the unlocked state, then the touch screen turns on the working mode of frequency hopping or increasing the working signal strength. The fingerprint identifier goes to sleep at time t6, and the touch screen turns off the working mode of frequency hopping or increasing the working signal strength. That is, the touch screen turns on the working mode of frequency hopping or increasing the working signal strength from time t5 to time t6. S105, the second module hops the frequency or increases the working signal strength.

[0217] The preset condition refers to that the frequency of the interference signal is within the sensitive frequency range of the second module component and the strength of the interference signal reaches a threshold value. The sensitive frequency range of the second module component is the range near the fundamental frequency or odd harmonics of the working signal of the second module component, for example, it can be between 0.9 and 1.1 times the working frequency of the second module component.

[0218] In some embodiments of the present application, the terminal may set a plurality of preselected frequency hopping frequencies. For example, the second module component operates at frequency 1, and the preselected frequencies include frequency 2, frequency 3, etc. When the second module component operates at frequency 1, an interference signal is detected, and the interference signal meets the preset conditions, the second module component switches the operating frequency to frequency 2. If the second module component still detects an interference signal when switching to frequency 2, and the interference signal meets the preset conditions, the second module component switches the operating frequency to frequency 3 again. And so on, until the interference signal is not enough to affect the normal operation of the second module component. In some other embodiments of the present application, the terminal may set a frequency interval. When the second module component detects an interference signal, and the interference signal meets the preset conditions, the operating frequency of the second module component may be switched in the frequency interval according to a certain algorithm, for example: switching in a linear stepping manner according to a fixed value (e.g., 2 kHz). The present application embodiment does not limit the specific frequency hopping method of the touch screen.

[0219] For example, taking the second module as a touch screen, the specific frequency hopping can be achieved by adjusting the counter through the crystal oscillator and frequency divider inside the touch sensor in the touch screen. The specific frequency hopping implementation method can refer to the existing technology and will not be repeated here.

[0220] For example, taking the second module assembly as a touch screen, the second module assembly can increase the working signal strength by adjusting the output level of the budget amplifier part in the touch screen sensor to adjust the working signal strength.

[0221] It can be seen that in the solution provided by the embodiment of the present application, when it is determined that both the first module and the second module are in working state, the second module starts the working mode of frequency hopping or increasing the working signal strength. Then, after determining that the detected interference signal meets the preset conditions, the second module hops the frequency or increases the working signal strength, thereby reducing the interference between the first module and the second module.

[0222] Furthermore, in the embodiment of the present application, since any one of the first module assembly and the second module assembly is in a non-working state (including a dormant state, a closed state, etc.) or both are in a non-working state, the terminal can not turn on (or turn off) the working mode of frequency hopping or improving the working signal strength. For example: when the fingerprint identifier is in a dormant state, it can be considered that the fingerprint identifier is in a non-working state, and at this time the touch screen does not turn on (or turn off) the working mode of frequency hopping or improving the working signal strength. For another example: when the touch screen is in a screen-off state or a screen-locked state, it can be considered that the touch screen is in a non-working state, and at this time the touch screen can not turn on (or turn off) the working mode of frequency hopping or improving the working signal strength. It can be seen that the embodiment of the present application reduces the time for the second module assembly to turn on the working mode of frequency hopping or improving the working signal strength, and reduces the time for the second module assembly to periodically query the results of the interference signal and determine whether the interference signal meets the preset conditions, which is conducive to saving the power consumption of the terminal and improving the response speed of the second module assembly.

[0223] It should be noted that the first module assembly can communicate with the second module assembly directly or indirectly through an intermediate module. Step S103 can be replaced by steps S103a-S103b.

[0224] like Figure 8 As shown, a flow chart of another touch device working method is provided for the embodiment of the present application, and the method further includes: S101-S102, S103a, S103b, and S104-S105, which are specifically as follows:

[0225] S103a. The first module sends first information to the processor.

[0226] Exemplarily, the processor may be an application processor or a system on chip (SOC). The processor here may also be other hardware that is communicatively connected to the first module component and the second module component respectively, which is not limited in the embodiments of the present application.

[0227] In some embodiments of the present application, the first information may be the working mode of the first module component, and the processor may further determine whether to notify the second module component to start the working mode of frequency hopping or improving the working signal strength according to the working mode of the first module component. The determination method of the processor is similar to the determination method of the first module component in step S103c, and is not repeated here.

[0228] Optionally, the processor may directly send the working mode of the first module assembly to the second module assembly, and the second module assembly determines whether to start the frequency hopping or improve the working signal strength working mode. The specific determination method of the second module assembly is similar to the determination method of the first module assembly in step S103c, which is not repeated here.

[0229] In some other embodiments of the present application, the first information is to notify the second module component to start the frequency hopping of the second module component or to increase the working signal strength of the working mode. The processor can directly forward the notification to the second module component.

[0230] S103b. The processor sends second information to the second module.

[0231] In some embodiments of the present application, Fig. 9 As shown, the first information may include the working mode of the first module component ( Fig. 9 The processor determines whether to notify the second module to start the frequency hopping or improve the working signal strength working mode according to the first information (shown in step S103a). Fig. 9 Then, the second information is different from the first information, and the second information is to notify the second module to start the frequency hopping or improve the working signal strength ( Fig. 9 3 (shown as step S103b).

[0232] In other embodiments of the present application, Fig.10 As shown, the first information may include the working mode of the first module component ( Fig.10 The processor directly sends the working mode of the first module assembly to the second module assembly (shown in step S103a). Fig.10 Then, the second information may be the same as the first information, which is the working mode of the first module.

[0233] In some other embodiments of the present application, Fig.11 As shown, when the first information is a working mode for notifying the second module component to start frequency hopping or to increase the working signal strength, the second information may be the same as the first information, which is a working mode for notifying the second module component to start frequency hopping or to increase the working signal strength ( Fig.11 3 and 4).

[0234] The second module receives the second information sent by the processor. In some embodiments of the present application, the second information is the working mode of the first module, and the second module needs to first determine whether to turn on the working mode of frequency hopping or improving the working signal strength, and then execute step S104. In other embodiments of the present application, the second information is to notify the second module to turn on the working mode of frequency hopping or improving the working signal strength, and the second module directly executes step S104.

[0235] For other contents, please refer to the relevant contents of the above embodiments, which will not be repeated here.

[0236] Optionally, after detecting that the interference signal meets the preset condition, the first module may also perform frequency hopping or reduce the working signal strength of the first module. That is, step S105 may be replaced by steps S106-S107.

[0237] like Fig.12 As shown, another flow chart of a touch device working method is provided for the embodiment of the present application, the method comprising: S101-S103, S104, S106, and S107, or as Fig.13 As shown, the method includes: S101-S102, S103a, S103b, S104, S106a, S106b, and S107, which are specifically as follows:

[0238] S106: If the second module component detects that the interference signal meets a preset condition, the second module component sends third information to the first module component.

[0239] The third information may be used to notify the first module to hop frequency or reduce the working signal strength of the first module. The third information may also be used to notify the first module that the interference of the first module to the second module also meets the preset condition, so that the first module determines to hop frequency or reduce the working signal strength of the first module.

[0240] Similarly, the second module assembly can communicate with the first module assembly directly or indirectly through other modules. That is, step S106 can be replaced by steps S106a and S106b.

[0241] S106a: If the second module component detects that the interference signal meets a preset condition, the second module component sends third information to the processor.

[0242] The third information may be used to notify the first module to hop frequency or reduce the working signal strength of the first module. The third information may also be used to notify the first module that the interference of the first module to the second module also meets the preset condition, so that the first module determines to hop frequency or reduce the working signal strength of the first module.

[0243] Exemplarily, the processor may be a specific application processor, or a system on chip (SOC). The processor here may also be other hardware that is communicatively connected to the first module component and the second module component respectively, which is not limited in the embodiments of the present application.

[0244] The preset condition refers to that the frequency of the interference signal is within the sensitive frequency range of the second module component and the strength of the interference signal reaches a threshold value. The sensitive frequency range of the second module component is the range near the fundamental frequency or odd harmonics of the working signal of the second module component, for example, it can be between 0.9 and 1.1 times the working frequency of the second module component.

[0245] S106b. The processor sends fourth information to the first module.

[0246] The fourth information may have the same content as the third information, and is used to notify the first module component to hop frequency or reduce the working signal strength of the first module component. The third information may also be used to notify the first module component that the interference of the first module component to the second module component meets a preset condition, so that the first module component determines to hop frequency or reduce the working signal strength of the first module component.

[0247] S107: The first module hops frequency or reduces the working signal strength.

[0248] In some embodiments of the present application, the terminal may set a plurality of preselected frequency hopping frequencies. For example, the first module operates at frequency 4, and the preselected frequencies include frequency 5, frequency 6, etc. When the first module operates at frequency 4, the second module detects an interference signal, and the interference signal satisfies a preset condition, then the first module switches the operating frequency to frequency 5. If the second module still detects an interference signal when switching to frequency 5, and the interference signal satisfies a preset condition, the first module switches the operating frequency to frequency 6 again. And so on, until the interference signal is not enough to affect the normal operation of the second module. In some other embodiments of the present application, the terminal may set a frequency interval. When the second module detects an interference signal, and the interference signal satisfies a preset condition, the operating frequency of the first module may be switched in the frequency interval according to a certain algorithm, for example, switching in a linear stepping manner according to a fixed value (e.g., 2 kHz). The present application embodiment does not limit the specific frequency hopping mode of the touch screen.

[0249] For example, taking the first module as fingerprint recognition, the specific frequency hopping can be achieved through the crystal oscillator and frequency divider inside the fingerprint sensor, and through the adjustment of the counter. The specific implementation method of frequency hopping can refer to the existing technology, which will not be repeated here.

[0250] For example, taking the first module component as a fingerprint identifier, the first module component can reduce the working signal strength through the budget amplifier part in the fingerprint sensor, and adjust the working signal strength by adjusting the output level.

[0251] For other contents of the embodiments of the present application, reference can be made to the relevant contents of the above embodiments and will not be repeated here.

[0252] Furthermore, considering that both the fingerprint reader and the touch screen are in working state, and when the fingerprint reader and the touch screen are touched at the same time, there is mutual interference between the fingerprint reader and the touch screen. Therefore, it is also possible to turn on the frequency hopping of the touch screen or increase the working signal strength when the touch screen is in working state and a touch is detected. In this way, it is also possible to reduce the working time of the terminal turning on the frequency hopping of the touch screen or increasing the working signal strength, which is conducive to reducing the power consumption of the terminal.

[0253] That is to say, the embodiment of the present application also provides a method for operating a touch control device, such as Fig.14 As shown, the method specifically includes S201-S203, as follows:

[0254] S201: Detect that the touch screen is in working state and is touched.

[0255] Exemplarily, the terminal detects that the touch screen receives an unlock command or is in an unlock state, and the touch screen is considered to be in a working state. The terminal detects that the touch screen receives an unlock command, including: the fingerprint identifier is in a legal unlocking working mode, detects the user's legal fingerprint information, and after successful comparison, sends an unlock command to the touch screen or to the touch screen through the processor.

[0256] S202: The touch screen starts a working mode of frequency hopping or increasing the working signal strength.

[0257] Before or at the same time as this step, the touch screen starts to detect interference signals, specifically the frequency and strength of the interference signals. After the touch screen turns on the working mode of frequency hopping or increasing the working signal strength, the touch screen periodically reads the detection results.

[0258] S203: If the interference signal is detected to meet the preset condition, the touch screen performs frequency hopping or increases the working signal strength.

[0259] Among them, the preset conditions are that the frequency of the interference signal is within the sensitive frequency range of the touch screen operating frequency (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 within the sensitive range of the touch screen operating frequency, which will affect the operation of the touch screen. The intensity of the interference signal reaches a certain threshold, which will cause the touch screen to work abnormally.

[0260] Optionally, after detecting that the interference signal meets the preset conditions, the fingerprint identifier may also hop frequency or reduce the working signal strength of the fingerprint identifier to reduce the interference of the fingerprint identifier on the touch screen. In other words, step S203 can be replaced by steps S203a-S203b. In other words, the working method of the touch control device specifically includes S201-S202, 203a and S203b, as follows:

[0261] S203a: If the interference signal detected meets the preset condition, the touch screen sends fourth information to the fingerprint identifier.

[0262] The fourth information can be used to notify the fingerprint identifier to hop frequency or reduce the working signal strength of the fingerprint identifier. The fourth information can also be used to notify the fingerprint identifier that the interference of the fingerprint identifier on the touch screen also meets the preset conditions so that the fingerprint identifier determines to hop frequency or reduce the working signal strength.

[0263] S203b, the fingerprint reader hops frequency or reduces the working signal strength.

[0264] This step may refer to step S107.

[0265] It is understandable that the touch screen can communicate with the fingerprint reader directly or indirectly through other hardware such as a processor. In other words, S203a can be replaced by S204 and S205. Fig.15 FIG. 1 is a flow chart of another working method of a touch control device provided in an embodiment of the present application. The method specifically includes: S201-S202, S204-S205, S203b, which are specifically as follows:

[0266] S204: If the detected interference signal meets a preset condition, the touch screen sends fifth information to the processor.

[0267] Exemplarily, the processor may be an application processor or a SOC. The processor here may also be other hardware that is respectively communicatively connected to the touch screen and the fingerprint reader, which is not limited in the embodiments of the present application.

[0268] The fifth information can be used to notify the fingerprint identifier to hop frequency or reduce the working signal strength of the fingerprint identifier. The fifth information can also be used to notify the fingerprint identifier that the interference of the fingerprint identifier on the touch screen also meets the preset conditions so that the fingerprint identifier determines to hop frequency or reduce the working signal strength.

[0269] S205. The processor sends fifth information to the fingerprint identifier.

[0270] For other contents of the embodiments of the present application, reference can be made to the relevant contents of the other embodiments mentioned above and will not be repeated here.

[0271] Considering that both the fingerprint reader and the touch screen are in working state, and when the fingerprint reader and the touch screen are touched at the same time, there is mutual interference between the fingerprint reader and the touch screen. Moreover, in the actual use of the terminal by the user, the time consumed from the fingerprint reader being awakened to the fingerprint reader being dormant is relatively short. Therefore, the terminal can also turn on the frequency hopping of the touch screen or increase the working signal strength after the fingerprint reader detects the touch operation. Subsequently, if it is detected that the fingerprint reader is in a dormant state, or it is detected that the terminal is in a screen-off state, the frequency hopping of the touch screen or the working mode of increasing the working signal strength is turned off. In this way, the working time of the terminal turning on the frequency hopping of the touch screen or increasing the working signal strength can also be reduced, which is beneficial to reducing the power consumption of the terminal.

[0272] Specifically, the embodiment of the present application also provides a method for operating a touch control device, such as Fig.17 As shown, the method specifically includes S301-S304, as follows:

[0273] S301: The fingerprint identifier detects a touch operation.

[0274] S302: The fingerprint identifier notifies the touch screen to start a frequency hopping operation or to increase the working signal strength.

[0275] For example: See Fig.16 In (1), when the terminal is in the screen-off and locked state, the fingerprint reader detects the user's touch operation at time t2, and the fingerprint reader notifies the touch screen to turn on the frequency hopping or increase the working signal strength. For another example: when the terminal is in the unlocked state, the fingerprint reader detects the user's touch operation at time t5, and the fingerprint reader notifies the touch screen to turn on the frequency hopping or increase the working signal strength.

[0276] For example: See Fig.16 In (2), when the terminal is in the locked screen state, the fingerprint identifier detects the user's touch operation at time t2, and the fingerprint identifier notifies the touch screen to start the frequency hopping or increase the working signal strength working mode.

[0277] S303: The touch screen starts a working mode of frequency hopping or increasing the working signal strength.

[0278] S304: If the touch screen detects that the interference signal meets a preset condition, the touch screen performs frequency hopping or increases the strength of the working signal.

[0279] In some embodiments of the present application, if the fingerprint reader does not detect a touch operation again within a preset time, it goes into sleep mode. In some embodiments of the present application, the fingerprint reader notifies the touch screen to turn off the frequency hopping or increase the working signal strength before determining to go into sleep mode, or while going into sleep mode, or after going into sleep mode. In other embodiments of the present application, the touch screen may actively obtain information on whether the fingerprint reader is in sleep mode, and when it is determined that the fingerprint reader is in sleep mode, turn off the frequency hopping or increase the working signal strength. The touch screen and the fingerprint reader may communicate directly or indirectly through other hardware.

[0280] For example: See Fig.16 In (1), the fingerprint reader is dormant at time t4, and the touch screen turns off the frequency hopping or increases the working signal strength. For another example: the fingerprint reader is dormant at time t6, and the touch screen turns off the frequency hopping or increases the working signal strength.

[0281] For example: See Fig.16 In (2), the fingerprint reader goes into sleep mode at time t9, and the touch screen turns off the frequency hopping or increases the working signal strength.

[0282] In some other embodiments of the present application, if the terminal detects a screen lock operation by the user or detects that the terminal screen is turned off, the touch screen turns off the working mode of frequency hopping or increasing the working signal strength.

[0283] For example: See Fig.16 In (2), the touch screen detects that the screen is off at time t8, and then the touch screen turns off the frequency hopping or increases the working signal strength working mode.

[0284] Step S304 may also be replaced by S304a-S304b.

[0285] S304a: If the interference signal detected meets the preset condition, the touch screen sends sixth information to the fingerprint identifier.

[0286] The sixth information can be used to notify the fingerprint identifier to hop frequency or reduce the working signal strength of the fingerprint identifier. The sixth information can also be used to notify the fingerprint identifier that the interference of the fingerprint identifier to the touch screen also meets the preset conditions so that the fingerprint identifier determines to hop frequency or reduce the working signal strength.

[0287] S304b, the fingerprint identifier hops frequency or reduces the working signal strength.

[0288] For other contents of the embodiments of the present application, such as the fingerprint identifier notifying the touch screen to enter a frequency hopping mode or to increase the working signal strength working mode and subsequent steps, refer to the relevant contents of the above-mentioned other embodiments and will not be repeated here.

[0289] In some embodiments of the present application, the terminal may also turn on the frequency hopping of the touch screen or increase the working signal strength when the fingerprint reader is in working state and the touch screen is on. Subsequently, if it is detected that the fingerprint reader is in a dormant state, or if it is detected that the terminal is in an off-screen state, turn off the frequency hopping of the touch screen or increase the working signal strength. In this way, it is also possible to reduce the working time of the terminal turning on the frequency hopping of the touch screen or increasing the working signal strength, which is conducive to reducing the power consumption of the terminal.

[0290] It is understandable that the above step 301 may also include the fingerprint identifier determining that the touch screen is on, that is, the fingerprint identifier detects the touch and determines that the touch screen is on, and notifies the touch screen to start the frequency hopping or increase the working signal strength working mode.

[0291] Alternatively, the fingerprint reader detects a touch operation and notifies the touch screen to start a frequency hopping or work mode with increased signal strength. After receiving the notification from the fingerprint reader, the touch screen determines that it is in a screen-on state and then starts a frequency hopping or work mode with increased signal strength. Specifically, the present application also provides a method for the operation of a touch device, such as Fig.18 As shown, the method specifically includes S301-S302, S303a, S304, as follows:

[0292] S303a. After the screen turns on, the touch screen starts a working mode of frequency hopping or increasing the working signal strength.

[0293] After receiving the notification, the touch screen detects whether it is in a light-on state and determines whether to start frequency hopping or increase the working signal strength.

[0294] For example: See Fig.16 In (1), at time t3, the touch screen is unlocked and the screen is lit, and the touch screen determines to start the working mode of frequency hopping or increasing the working signal strength.

[0295] For example: See Fig.16 In (2), at time t7, the touch screen is unlocked and the screen is lit, and the touch screen determines to start the working mode of frequency hopping or increasing the working signal strength.

[0296] For other contents of the embodiments of the present application, reference can be made to the relevant contents of other embodiments mentioned above, and no further repetition will be given.

[0297] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
