[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to a Chinese patent application filed with the China Patent Office on March 21, 2024, with application number 202410331897.X and application name “Detection method, system and electronic device for screen protector”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The embodiments of the present application relate to the field of terminal technology, and in particular to a method and system for detecting a screen protector and an electronic device. Background Art

[0004] Currently, users often install screen protectors on their electronic devices to prevent scratches and nicks. However, these screen protectors can affect the performance of the touchscreen. For example, touch sensitivity, screen brightness, and stylus writing performance may differ between devices with and without screen protectors.

[0005] Therefore, it is necessary to develop a solution that can detect whether an electronic device is installed with a screen film. Summary of the Invention

[0006] Embodiments of the present application provide a method, system, and electronic device for detecting a screen protector, which can detect whether an electronic device is installed with a screen film.

[0007] In a first aspect, an embodiment of the present application provides a method for detecting a screen protector, which is applied to an electronic device, the electronic device including a touch screen, the method comprising: in response to a touch operation on a first area of ​​the touch screen, obtaining target touch data of a second area of ​​the touch screen, the first area and the second area corresponding to and spaced from each other; determining a relationship between the electronic device and the screen protector based on the target touch data, the relationship including whether the electronic device is installed with or not installed with a screen protector; the screen protector comprising at least one group of sensing units, the sensing units comprising a first sensing area, a second sensing area, and a conductive component for connecting the first sensing area and the second sensing area; wherein, when the screen protector is installed on the touch screen, the first sensing area corresponds to the first area and the first sensing area obtains a sensing signal based on the touch operation on the first area, the second sensing area corresponds to the second area, the conductive component is used to transmit the sensing signal to the second sensing area, and the sensing signal is used to trigger the second area to generate preset touch data.

[0008] In an embodiment of the present application, an electronic device obtains target touch data of a second area of ​​the touch screen in response to a touch operation on a first area of ​​the touch screen. The target touch data of the second area can be used to detect whether the electronic device is installed with a screen protector. In particular, the target touch data of the second area can be used to automatically identify whether the electronic device is installed with a screen protector without the user's knowledge. Detecting whether an electronic device is installed with a screen protector can be achieved by simply judging the target touch data. This method requires little computation and is easy to implement, and can provide a reliable basis for subsequent improvements to the performance of the electronic device. For example, after the electronic device senses the presence of a screen protector, its performance can be improved and the functional mode of the touch screen can be optimized to avoid a decrease in the touch screen's touch sensitivity, screen brightness, writing effect, and other performance after the touch screen is installed with a screen protector. This ensures that the touch screen has the same performance with and without a screen protector installed, such as the touch sensitivity, screen brightness, display color, and stylus writing effect of the touch screen before and after the screen protector is installed.

[0009] In one possible implementation, the preset touch data is touch data that meets preset conditions, and the preset conditions are related to the size or area of ​​the first sensing area and the second sensing area; determining the relationship between the electronic device and the screen protector based on the target touch data includes: when the target touch data belongs to the preset target touch data, determining that the relationship between the electronic device and the screen protector is that the electronic device is installed with a screen protector; when the target touch data does not belong to the preset target touch data, determining that the relationship between the electronic device and the screen protector is that the electronic device is not installed with a screen protector.

[0010] In the embodiments of the present application, by setting the size or area of ​​the first and second sensing areas, corresponding preset touch data can be set, making it easy to adjust the preset touch data. This allows for the continuous expansion of touch data for different preset conditions based on product development, resulting in strong scalability and practicality. With the preset touch data already set, subsequent determination of whether an electronic device is equipped with a screen protector can be made efficiently and accurately based on the target touch data.

[0011] In one possible implementation, the preset condition includes: the number of first sensing values ​​in the touch data is a first preset number, wherein the first sensing value is a sensing value greater than a first threshold, and the first preset number is set according to the size or area of ​​the first sensing area and the second sensing area.

[0012] It is understandable that since a person's fingertip also has a certain area, when a person's fingertip touches the touch screen, it will affect the sensing value of a corresponding area on the touch screen. For example, if the touch screen is a capacitive touch screen, it will affect the value of the capacitive feature point (i.e., the capacitance value) corresponding to a certain area on the touch screen.

[0013] In an embodiment of the present application, the touch data includes sensing values. By setting the number of first sensing values ​​to distinguish the touch data generated by the user's touch operation, that is, the first preset number of preset conditions, it is possible to well distinguish whether the touch data is generated based on the touch operation or based on the sensing signal, thereby avoiding misidentification.

[0014] In one possible implementation, the method further includes: when it is determined that the electronic device is installed with a screen protector, determining the type of the screen protector; adjusting the functional mode of the touch screen to match the type of the screen protector, the functional mode including one or more of the following: touch sensitivity, display brightness, display color, and display of writing handwriting.

[0015] In the embodiments of the present application, after the electronic device senses the presence of a screen protector, it can improve its performance and optimize the functional mode of the touch screen to avoid a decrease in touch screen sensitivity, screen brightness, writing quality, and other performance after the touch screen is installed with the screen protector. This ensures that the touch screen has the same user experience with and without the screen protector installed. For example, the touch screen's touch sensitivity, screen brightness, display color, and stylus writing quality are consistent before and after the screen protector is installed. Furthermore, different functional modes can be provided for different types of screen protectors to better provide users with the best user experience.

[0016] In one possible implementation, determining the type of the screen protector includes: determining the type of the screen protector based on the number of first sensing values ​​in the target touch data, and / or determining the type of the screen protector based on the number of areas, where the number of areas is the number of second areas corresponding to the first area.

[0017] In the embodiment of the present application, the number of first sensing values ​​is related to the size or area of ​​the first sensing area and the second sensing area, and the second sensing area corresponds to the second area. Therefore, by setting corresponding sensing units for different types of screen protectors, the type of screen protector can be distinguished by the number of first sensing values ​​or the number of second areas, which has strong operability.

[0018] In one possible implementation, before responding to a touch operation on a first area of ​​the touch screen, the method further includes: detecting a first operation on the touch screen and obtaining touch data to be processed; determining first touch data in the touch data to be processed that meets a touch condition, the touch condition including that the number of second sensing values ​​in the touch data is a second preset number, and that the areas on the touch screen corresponding to each second sensing value are continuous, and that the second sensing values ​​are sensing values ​​greater than a second threshold; when the area corresponding to the first touch data is the first area, determining that the first operation is a touch operation on the first area.

[0019] In an embodiment of the present application, when an electronic device is installed with a screen protector and a touch operation is performed on the first area but not on the second area, the second area can generate preset touch data based on the sensing signal, thereby determining whether a touch operation has occurred on the first area on the touch screen through the touch conditions. The setting of the touch conditions can more accurately determine whether a touch operation has occurred.

[0020] In one possible implementation, determining the relationship between the electronic device and the screen protector based on the target touch data includes: when the second preset number is greater than the number of first sensing values ​​in the target touch data, determining the relationship between the electronic device and the screen protector based on the target touch data; when the second preset number is less than or equal to the number of first sensing values, not determining the relationship between the electronic device and the screen protector.

[0021] In the embodiment of the present application, when the second preset number is greater than the number of first sensing values ​​in the target touch data, it means that the user has performed a touch operation on the first area but not on the second area. When the second preset number is less than or equal to the number of first sensing values, it means that the user may have performed a touch operation on both the first area and the second area.

[0022] In one possible implementation, the touch condition includes a finger touch condition and / or a stylus touch condition; the second threshold in the finger touch condition is smaller than the second threshold in the stylus touch condition; and the second preset number in the finger touch condition is greater than the second preset number in the stylus touch condition.

[0023] In the embodiment of the present application, corresponding touch conditions are set based on the difference between finger touch and stylus touch to improve the accuracy of touch operation recognition.

[0024] In a possible implementation, the method further includes: in response to a second operation, displaying a guide graphic, the guide graphic being used to indicate positions of the first area and the second area, and the second operation being used to instruct detection of a screen protector.

[0025] In an embodiment of the present application, the user may be guided to automatically select whether to perform screen protector detection, so as to provide the user with a corresponding functional mode after determining that the screen protector is installed.

[0026] In one possible implementation, different types of screen protectors correspond to different guide graphics; displaying the guide graphics includes: obtaining the type of screen protector to be detected; displaying the guide graphics corresponding to the type of screen protector, and the corresponding guide graphics are used to indicate the positions of the first area and the second area corresponding to the type of screen protector.

[0027] In an embodiment of the present application, the user can also be guided to automatically select whether to perform screen protector detection, so that after determining that the screen protector is installed, corresponding functional modes can be provided to the user based on different screen protector types.

[0028] In a possible implementation, the sensing value in the touch data includes: a capacitance value, a voltage value, a current value, or a magnetic flux.

[0029] In the embodiment of the present application, the sensing values ​​in the touch data can all be detected and collected by the touch detection component of the touch screen, and the data source is reliable, thereby providing a reliable basis for subsequently determining whether the target touch data meets the preset conditions.

[0030] In a second aspect, an embodiment of the present application provides a screen protector detection system, comprising an electronic device and a screen protector: the electronic device comprises a touch screen and a processor, the processor being configured to execute the following method: in response to a touch operation on a first area of ​​the touch screen, obtaining target touch data of a second area of ​​the touch screen, the first area corresponding to the second area and being spaced apart from each other; determining a relationship between the electronic device and the screen protector based on the target touch data, the relationship including whether the electronic device is installed with or without a screen protector; the screen protector comprising at least one group of sensing units, the sensing units comprising a first sensing area, a second sensing area, and a conductive component for connecting the first sensing area and the second sensing area; wherein, when the screen protector is installed on the touch screen, the first sensing area corresponds to the first area and the first sensing area obtains a sensing signal based on the touch operation on the first area, the second sensing area corresponds to the second area, the conductive component is configured to transmit the sensing signal to the second sensing area, and the sensing signal is configured to trigger the second area to generate preset touch data.

[0031] In an embodiment of the present application, an electronic device obtains target touch data of a second area of ​​the touch screen in response to a touch operation on a first area of ​​the touch screen. The target touch data of the second area can be used to detect whether the electronic device is installed with a screen protector. In particular, the target touch data of the second area can be used to automatically identify whether the electronic device is installed with a screen protector without the user's knowledge. Detecting whether an electronic device is installed with a screen protector can be achieved by simply judging the target touch data. This method requires little computation and is easy to implement, and can provide a reliable basis for subsequent improvements to the performance of the electronic device. For example, after the electronic device senses the presence of a screen protector, its performance can be improved and the functional mode of the touch screen can be optimized to avoid a decrease in the touch screen's touch sensitivity, screen brightness, writing effect, and other performance after the touch screen is installed with a screen protector. This ensures that the touch screen has the same performance with and without a screen protector installed, such as the touch sensitivity, screen brightness, display color, and stylus writing effect of the touch screen before and after the screen protector is installed.

[0032] In a possible implementation, the first sensing region and the second sensing region have different areas and / or sizes.

[0033] In the embodiment of the present application, the area and / or size of the first sensing area and the second sensing area are set to set a preset condition, or to set different types of screen protectors.

[0034] In a possible implementation, the first sensing area and the second sensing area are both smaller than or equal to a first area and larger than or equal to a quarter of the first area, where the first area is the area of ​​a sensing module on the touch screen.

[0035] In the embodiment of the present application, the first sensing area and the second sensing area are both smaller than the first area to avoid affecting the normal usage process of the user.

[0036] In one possible implementation, the length of the conductive component is greater than a preset length, and the width of the conductive component is less than the smallest side length of the first sensing area and the second sensing area. The preset length is used to indicate the length occupied by a finger when touching the touch screen.

[0037] In the embodiment of the present application, the preset length can ensure that the user's normal operation will not accidentally touch the first sensing area and the second sensing area at the same time, providing a reliable basis for subsequent screen protector detection.

[0038] In a possible implementation, the screen protector includes two or more groups of sensing units, and any group of sensing units is arranged around the screen protector.

[0039] In the embodiment of the present application, by evenly distributing the sensing units around the screen protector, positions that are easily touched by fingers can be covered as much as possible.

[0040] In a third aspect, an embodiment of the present application provides an electronic device, comprising: a processor and a touch screen; when the program instructions are executed by the processor, the electronic device executes any of the above screen protector detection methods to detect whether a screen protector is installed on the touch screen.

[0041] The technical effect obtained by the above-mentioned third aspect is similar to the technical effect obtained by the corresponding technical means in the first aspect, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] It is understood that the connection relationships described in this application refer to direct or indirect connections. For example, the connection between A and B can be either a direct connection between A and B, or an indirect connection between A and B via one or more other electrical components. For example, A and C can be directly connected, and C can be directly connected to B, so that A and B are connected through C.

[0069] It should be noted that the terms "first" and "second" in the specification, claims and drawings of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. In the specification, claims and drawings of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the term "plurality" in the specification, claims and drawings of this application refers to two or more than two.

[0070] It should also be noted that the method disclosed in the embodiments of the present application or the method shown in the flowchart includes one or more steps for implementing the method. Without departing from the scope of the claims, the execution order of multiple steps can be interchanged with each other, and some steps can also be deleted.

[0071] The following will describe some embodiments with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0072] As mentioned above, installing a screen protector on the touch screen of an electronic device can affect the performance of the touch screen. For example, the touch screen's touch sensitivity and screen brightness may decrease, affecting the writing effect of the stylus or causing touch interruptions during gaming.

[0073] In view of this, the embodiments of the present application provide a method for detecting a screen protector and related equipment, which can detect whether an electronic device is installed with a screen protector. In particular, it can automatically identify whether an electronic device is installed with a screen protector without the user's perception, that is, there is no need for the user to actively operate to detect whether the electronic device is installed with a screen protector. Instead, during the user's daily use of the electronic device, the electronic device can automatically detect whether a screen protector is installed, thereby providing a reliable basis for subsequent improvement of the performance of the electronic device. For example, after the electronic device senses the presence of a screen protector, it can improve its performance and optimize the functional mode of the touch screen to avoid a decrease in the touch sensitivity, screen brightness, writing effect and other performance of the touch screen after the touch screen is installed with a screen protector, and present to the user the same effect of using the touch screen with and without a screen protector, such as the touch sensitivity, screen brightness, display color, stylus writing effect, etc. of the touch screen are consistent before and after the screen protector is installed.

[0074] The screen protector detection method provided in the embodiments of this application can be applied to various electronic devices equipped with touch screens. The electronic devices can include mobile phones, tablet computers, e-readers, game consoles, wearable devices, in-vehicle devices, laptop computers, personal digital assistants (PDAs), etc. This application does not impose any restrictions on the specific type of electronic device.

[0075] The following uses a mobile phone as an example of an electronic device to exemplify the application scenario of the screen protector detection method provided in the embodiment of the present application.

[0076] As shown in FIG1 , the electronic device 10 is not equipped with a screen protector 20, and the touch screen 11 of the electronic device 10 is not covered by the screen protector 20. The user's touch operation can be directly applied to the touch screen 11, such as by directly contacting the touch screen 11 with a finger or other part of the user's body, or by directly contacting the touch screen 11 with an input device such as a stylus.

[0077] As shown in Figures 2A and 2B, the electronic device 10 is installed with a screen protector 20, and the touch screen 11 of the electronic device 10 is covered by the screen protector 20. Installing the screen protector 20 on the electronic device 10 means installing the screen protector 20 on the touch screen 11 of the electronic device 10 so that the touch screen 11 is protected by the screen protector 20. When the screen protector 20 is installed on the electronic device 10, the user's touch operation directly acts on the screen protector 20. For example, the user's fingers or other parts of the body or the user's input device such as a stylus directly contact the screen protector 20, but cannot directly contact the touch screen 11. The touch screen 11 can receive the user's touch operation through the screen protector 20.

[0078] It can be understood that when the screen protector 20 is installed on the electronic device 10 , the screen protector 20 is fixed on the electronic device 10 , and the electronic device 10 and the screen protector 20 are relatively stationary.

[0079] It can be understood that when the screen protector 20 is installed on the electronic device 10, it can completely cover the touch screen 11 or partially cover the touch screen 11. The specific setting can be based on actual conditions, and the embodiment of the present application does not make specific limitations on this.

[0080] It can be understood that Figures 1, 2A and 2B are only examples. The relationship between the electronic device 10 and the touch screen 11, as well as the relationship between the touch screen 11 and the screen protector 20 can be set according to actual conditions, and the embodiments of the present application do not specifically limit this.

[0081] Please refer to FIG3 , which exemplarily introduces the structure of the electronic device provided in an embodiment of the present application.

[0082] The electronic device 10 may include a touch screen 11, a processor 12, a memory 13, and a sensor module 14. The sensor module 14 includes but is not limited to a touch sensor 14A, a capacitive sensor 14B, an electromagnetic sensor 14C, and a pressure sensor 14D.

[0083] The processor 12 may include one or more processing units, for example: the processor 12 may include an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural network processing unit (NPU), etc. Among them, different processing units can be independent devices or integrated into one or more processors, for example, integrated into a system on a chip (SoC). A memory can also be provided in the processor 12 for storing instructions and data. In some embodiments, the memory in the processor 12 is a cache memory. The memory can save instructions or data that the processor 12 has just used or recycled.

[0084] In some embodiments, the processor 12 may include one or more interfaces. The interfaces may include an inter-integrated circuit (I2C) interface, an inter-integrated circuit sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver / transmitter (UART) interface, a mobile industry processor interface (MIPI), a general-purpose input / output (GPIO) interface, a subscriber identity module (SIM) interface, and / or a universal serial bus (USB) interface.

[0085] The memory 13 can be used to store computer executable program code, and the executable program code includes instructions. The memory 13 may include a program storage area and a data storage area. The program storage area may store an operating system, application programs required for at least one function (such as a sound playback function, an image playback function, etc.), etc. The data storage area may store data created during the use of the electronic device 10 (such as audio data, a phone book, etc.), etc. In addition, the memory 13 may include one or more storage units, for example, it may include volatile memory (volatile memory), such as dynamic random access memory (DRAM), static random access memory (SRAM), etc.; it may also include non-volatile memory (NVM), such as read-only memory (ROM), flash memory, etc. The processor 12 executes various functional applications and data processing of the electronic device 10 by running instructions stored in the memory 13 and / or instructions stored in a memory provided in the processor.

[0086] It should be noted here that the operating system referred to in the embodiments of this application includes but is not limited to Android operating system, IOS operating system, iPad OS operating system, Windows operating system, Linux operating system, MAC OS operating system, embedded system, etc.

[0087] The touch screen 11, also known as a "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive signals input by a stylus pen, finger, etc. Typically, the touch screen 11 includes a touch detection component, a touch screen controller, and a display panel. The display panel is used to display images, videos, etc. The touch detection component can be installed on the upper layer of the liquid crystal display device to detect touch information such as the user's touch position to collect touch signals and transmit the detected touch signals to the touch screen controller. The touch screen controller is used to process the touch signal and send the corresponding signal to the processor. Then, after processing the signal, the processor executes the corresponding response action, such as turning on and off the machine, opening an application, taking an image, taking a screenshot, or switching windows.

[0088] The display panel may be a liquid crystal display (LCD). The display panel may also be made of an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a mini-LED, a micro-LED, a micro-OLED, or a quantum dot light-emitting diode (QLED).

[0089] Among them, the touch screen controller is also called a touch chip. The touch screen controller can be used to output periodic drive signals to the touch screen and receive corresponding touch signals from the touch screen. When the user touches the touch screen, the touch signal changes.

[0090] The touch detection component may include but is not limited to the following touch sensor 14A, capacitive sensor 14B, electromagnetic time sensor 140C and pressure sensor 14D.

[0091] Touch sensor 14A, also known as a "touch device," can be disposed on touch screen 11. Touch sensor 14A is configured to detect touch operations applied thereto or in the vicinity thereof. Touch sensor 14A can transmit the detected touch operations to an application processor to determine the type of touch event. Visual output related to the touch operations can be provided via touch screen 11. In other embodiments, touch sensor 14A can also be disposed on the surface of electronic device 10, in a location different from that of touch screen 11.

[0092] Capacitive sensor 14B uses various types of capacitors as sensing elements, converting measured physical or mechanical quantities into changes in capacitance. It is essentially a capacitor with variable parameters. Capacitive sensor 14B can be an integrated circuit (IC) chip that collects capacitance signals. The IC chip can be composed of IC electrodes.

[0093] Exemplarily, the capacitive sensor 14B can be integrated in the capacitive touch area of ​​the front panel of the touch screen 11 to detect the touch signal of the finger, such as the capacitive signal, and send the detected touch signal to the touch screen controller so that the touch screen controller can process the touch signal.

[0094] Electromagnetic sensor 14C, also known as an "electromagnetic sensor" or "magnetoelectric sensor," converts a measured physical quantity into an induced electromotive force (EMF). Electromagnetic sensor 14C is also known as an electromagnetic induction or electrodynamic sensor. Electromagnetic sensor 14C is used to collect electromagnetic signals.

[0095] Pressure sensor 14D is used to sense pressure signals and convert them into electrical signals. The principles of pressure sensors utilize physical phenomena such as resistance, capacitance, electromagnetic induction, and the piezoelectric effect. In some embodiments, pressure sensor 14D can be provided on touch screen 11. There are many types of pressure sensors 14D, such as piezoelectric sensors, resistive pressure sensors, inductive pressure sensors, and capacitive pressure sensors.

[0096] A piezoelectric sensor is a sensor based on the piezoelectric effect. The piezoelectric effect can be divided into the direct piezoelectric effect and the inverse piezoelectric effect. The direct piezoelectric effect states that when a crystal is subjected to an external force in a fixed direction, internal polarization occurs, generating charges of opposite signs on two surfaces. When the external force is removed, the crystal returns to a neutral state. When the direction of the external force changes, the polarity of the charge also changes. The amount of charge generated by the crystal is proportional to the magnitude of the external force.

[0097] A capacitive pressure sensor may include at least two parallel plates made of conductive material. When a force acts on the pressure sensor, the capacitance between the electrodes changes. Electronic device 10 determines the intensity of the pressure based on the change in capacitance. When a touch operation is performed on touch screen 11, electronic device 10 detects the intensity of the touch operation using pressure sensor 14D. Electronic device 10 can also calculate the location of the touch based on the touch signal from pressure sensor 14D.

[0098] Resistive pressure sensors typically consist of a thin metal film and a substrate. The resistance of the thin metal film changes with pressure, forming a pressure-sensitive element. When pressure is applied to an object, the pressure-sensitive element deforms, changing the resistance of the thin metal film. This change in resistance is converted into an electrical signal. After processing through circuits such as amplifiers and filters, the output is a voltage or current signal proportional to the pressure applied to the object.

[0099] In some embodiments, the touch detection component is composed of multiple types of sensors, for example, an ACC sensor, a CAP sensor, a piezoelectric bending element, a piezoelectric film, a potentiometer, a variable magnetoresistive sensor, a piezoelectric sensor, a piezoresistive sensor, a servo sensor, a displacement sensor, a speed sensor, a vibration sensor, a micro-electromechanical system (MEMS) sensor, a gyroscope, a proximity sensor, an electro-microphone, a hydrophone, a condenser microphone, an electret condenser microphone, a dynamic microphone, a ribbon microphone, a carbon particle microphone, a piezoelectric microphone, an optical fiber microphone, a laser microphone, and a liquid microphone.

[0100] In some embodiments, the electronic device 10 may include 1 or N touch screens 11 , where N is a positive integer greater than 1.

[0101] In some embodiments, the electronic device 10 is foldable. Part or all of the foldable electronic device 10 can be bent. For example, the electronic device 10 includes two or more touch screens 11, and the two or more touch screens 11 can be folded.

[0102] In the embodiment of the present application, the electronic device 10 may further include the above-mentioned sensors, such as an ACC sensor, a shock sensor, and a vibration sensor.

[0103] When a user's palm, fingertips, fingernails, nails, side nails, knuckles, or other body parts, or an input device such as a stylus, touches the touch screen 11, a touch event occurs. The sensor of the electronic device 10 collects two types of raw signals:

[0104] The first type of raw signal is the motion signal collected by the ACC sensor, impact sensor, and vibration sensor when the surface of the touch screen 11 vibrates due to mechanical force applied by the user. This motion signal can be used to measure the magnitude of the mechanical force applied by the user to the touch screen 11. Under the influence of mechanical force, the electronic device 10 may switch from a stationary state to a moving state or vice versa. Therefore, this vibration signal can also be used to characterize the motion / stationary state of the electronic device 10 under the influence of mechanical force.

[0105] The second type of raw signal is the touch signal collected by touch detection components such as touch sensor 14A, capacitive sensor 14B, electromagnetic sensor 14C, pressure sensor 14D, piezoelectric sensor, and piezoresistive sensor. This touch signal is associated with the touch characteristics of the user's body part contacting the touch screen 11 and can be used to determine the type of touch event and whether to install a screen protector.

[0106] It should be understood that the structures illustrated in the embodiments of the present application do not constitute a specific limitation on the electronic device 10. In other embodiments of the present application, the electronic device 10 may include more or fewer components than shown, or may combine or separate certain components, or arrange the components differently. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0107] In the embodiment of the present application, the above-mentioned touch screen 11 may include but is not limited to: a touch screen using capacitive touch technology, a touch screen using electromagnetic induction (EMR) technology, a touch screen implemented using the piezoresistive effect, etc., and may also include other touch screens 11 that can generate preset touch data based on the sensing signal transmitted by the screen protector 20 after the screen protector 20 provided in the embodiment of the present application is installed. This application does not make specific limitations on this.

[0108] Capacitive touch technology includes, but is not limited to, surface capacitive touch technology and projected capacitive touch technology. A touch screen that uses capacitive touch technology can be called a capacitive touch screen or a capacitive touch screen. Specifically, it can be a self-capacitive touch screen, a mutual-capacitive touch screen, or a touch screen that combines self-capacitance and mutual-capacitance, which is not limited in the present embodiment.

[0109] Touchscreens using capacitive touch technology operate by leveraging the body's current sensing. The basic principle is to detect capacitance using charging time, and then detect changes in capacitance to obtain touch data. Capacitive touchscreens are made of materials such as alloys or indium tin oxide (ITO), where charge is stored in microscopic electrostatic networks. When a finger taps the screen, a small current is drawn from the contact point, causing a voltage drop at the corner electrodes. This process uses the weak current sensed by the human body to achieve touch control.

[0110] A touch screen that uses electromagnetic induction technology is also called an electromagnetic touch screen, or an electromagnetic touch screen.

[0111] The basic principle of a touch screen using electromagnetic induction technology is that a stylus emits electromagnetic signals, which interact with the electromagnetic induction plate behind the display screen. When the stylus approaches the touchscreen, the electromagnetic induction plate behind the touchscreen senses the pen's electromagnetic signal, causing the induction lines under the electromagnetic induction plate to change. The horizontal and vertical antenna arrays receive the signal. The stylus acts as the signal transmitter (transceiver) and the antenna array acts as the signal receiver (receiver). The X and Y coordinates of the stylus are calculated based on the changes in magnetic flux.

[0112] In some embodiments, since the stylus has a longitudinal pressure sensor, when the user writes or draws with the stylus, when the pen tip is subjected to force, the pressure is transmitted to the pressure sensor through the pen core. The change in pressure causes the electromagnetic signal emitted by the stylus to change, and the electromagnetic induction plate can display different pressure sensations according to the induction signal.

[0113] A touch screen that utilizes the resistance effect is also called a resistive touch screen, or a resistive touch screen.

[0114] Resistive touchscreens consist of two layers of transparent conductive film, sandwiched between them by a transparent insulating adhesive. The first layer of conductive film is connected by vertically arranged current leads, forming a square grid. The second layer of conductive film is connected by parallel current leads. The insulating adhesive between the two layers is designed to be evenly distributed in a dot pattern to prevent short circuits between the current leads between the two layers. Touchscreens are typically covered with a protective layer of glass or plastic to protect the conductive film from damage by hard external objects.

[0115] Resistive touchscreens operate based on the resistance effect. When an external force is applied to the touchscreen, the resistance between the conductive films changes, causing the voltage output by the touchscreen to change. By measuring this change in output voltage, the touchscreen's location can be determined.

[0116] The structure and working principle of the touch screen 11 are described in detail below by taking the touch screen 11 as a mutual capacitance screen as an example.

[0117] As shown in Figure 4, the mutual capacitance screen includes two layers of indium-tin-oxide (ITO) conductive glass. Different ITO conductive circuit modules are etched onto the two layers of ITO conductive glass. The two layers of conductive circuit modules are perpendicular to each other on the display panel of the mutual capacitance screen, forming horizontal and vertical electrodes. The horizontal and vertical electrodes can be thought of as sliders that continuously change in the X-axis and Y-axis directions. Because the horizontal and vertical electrodes are located on different surfaces, a capacitor node is formed where the two sets of electrodes intersect, meaning that the two sets of electrodes constitute the two poles of the capacitor (parasitic capacitance).

[0118] When measuring capacitance, the vertical electrodes sequentially emit excitation signals, while all horizontal electrodes receive the signals simultaneously. This determines the capacitance at the intersection of all horizontal and vertical electrodes, representing the two-dimensional capacitance of the entire mutual capacitance screen. Based on this two-dimensional capacitance change data, the coordinates of each touch point can be calculated.

[0119] It is understandable that the electronic device 10 can also send excitation signals sequentially through the horizontal electrodes, and all the vertical electrodes receive the signals simultaneously. This embodiment of the application is not limited to this. The electrodes that send excitation signals can be called driving electrodes, and the electrodes that receive signals can be called receiving electrodes.

[0120] The electronic device 10 provided in the present application may include one or more ITO layers, which are corroded to form multiple horizontal and vertical electrodes, and use independent chips that are staggered in rows and columns and have sensing functions to form an axis coordinate sensing module matrix of projected capacitance: the X and Y axes serve as separate rows and columns of the coordinate sensing module to detect the capacitance of each grid of the sensing module.

[0121] Figure 5A illustrates the structure of a sensing module provided by an embodiment of the present application. The sensing module includes a parasitic capacitor, Cp, formed by X-axis electrodes and Y-axis electrodes. The X-axis and Y-axis electrodes form a capacitor at their intersection, meaning these two groups of electrodes form the two poles of the capacitor.

[0122] As shown in 5B, when a finger touches the mutual capacitance screen, due to the human body's electric field, a coupling capacitor will be formed between the user and the touch screen surface. For high-frequency current, the capacitor is a direct conductor, so the finger will absorb a very small current from the contact point. As a result, the user's touch action causes the local capacitance in the touch screen 11 to change, and the capacitance of the finger will be superimposed on the capacitance of the screen body, that is, the capacitance value Cp of the parasitic capacitance will increase. The mutual capacitance screen detects the horizontal and vertical electrode arrays, and determines the horizontal coordinates and vertical coordinates respectively according to the changes in capacitance before and after the touch, and then combines them into the touch coordinates of the plane. Alternatively, the electronic device can query a pre-stored two-dimensional data table based on the change in capacitance of the touch screen 11 to know the coordinates of the touch point.

[0123] It can be understood that the structure shown in Figure 5A covers the entire capacitive touch screen. Each sensing module has its specific physical position in the capacitive touch screen. That is, the position of the capacitor is its X and Y coordinates on the capacitive touch screen. Therefore, the capacitive touch screen can be regarded as composed of capacitance values. There are multiple electrodes arranged in an array along the X-axis and Y-axis directions on the capacitive touch screen 1 to sense capacitance changes.

[0124] Please refer to FIG6 , which exemplarily introduces the screen protector provided in an embodiment of the present application.

[0125] The screen protector 20 includes at least one set of sensing units 200. The sensing units 200 include a first sensing area 21, a second sensing area 22, and a conductive component 23 for connecting the first sensing area 21 and the second sensing area 22.

[0126] In the embodiment of the present application, when the screen protector 20 is installed on the touch screen 11 of the electronic device 10 , each sensing area (such as the first sensing area 21 and the second sensing area 22 ) in any sensing unit 200 corresponds to a unique predetermined sensing position on the touch screen 11 .

[0127] For example, taking a set of sensing units 200 as an example (see also FIG7 ), when the screen protector 20 is installed on the touch screen 11, the first sensing area 21 is located on area 111. From a perspective perpendicular to the horizontal plane of the touch screen 11, the first sensing area 21 may fully or partially cover area 111. In other words, the first sensing area 21 corresponds to area 111 of the touch screen 11. Area 111 on the touch screen 11 is the predetermined sensing position uniquely corresponding to the first sensing area 21. When a user touches the first sensing area 21, they may also indirectly contact the first area 111 through the first sensing area 21. In other words, area 111 can sense the user's touch operation through the first sensing area 21. When the screen protector 20 is installed on the touch screen 11, the second sensing area 22 is located on area 112. From a perspective perpendicular to the horizontal plane of the touch screen 11, the second sensing area 22 may fully or partially cover area 112. In other words, the second sensing area 22 corresponds to area 112 of the touch screen 11. Area 112 on the touch screen 11 is the predetermined sensing position uniquely corresponding to the second sensing area 22. When a user touches the second sensing area 22, the user can also touch area 112 through the second sensing area 22, that is, area 112 can sense the user's touch operation through the second sensing area 22.

[0128] In the embodiment of the present application, when the screen protector 20 is installed on the touch screen 11 of the electronic device 10, each sensing area (e.g., the first sensing area 21 and the second sensing area 22) in any sensing unit 200 can obtain a sensing signal based on a touch operation at its unique corresponding predetermined sensing position. For example, a sensing signal can be obtained based on a touch signal generated at its unique corresponding predetermined sensing position, or based on a touch operation at the sensing area.

[0129] As in the above example, region 111 is the unique predetermined sensing location corresponding to first sensing region 21 on touch screen 11. When screen protector 20 is installed on touch screen 11 of electronic device 10, if a user touches first sensing region 21, first sensing region 21 can transmit the touch operation to region 111. Region 111 generates a corresponding touch signal based on the touch operation. First sensing region 21 can sense the touch signal, and then obtain a sensing signal based on the touch signal. The sensing signal is then transmitted to second sensing region 22 via conductive component 23. Similarly, second sensing region 22 can also obtain a sensing signal based on the touch operation on region 112.

[0130] For example, area 111 on the touch screen 11 is a predetermined sensing position uniquely corresponding to the first sensing area 21. When the screen protector 20 is installed on the touch screen 11 of the electronic device 10, if a user touches the first sensing area 21, the first sensing area 21 can obtain a sensing signal based on the touch operation, and area 111 can also obtain a touch signal based on the touch operation. Similarly, the second sensing area 22 can also obtain a sensing signal based on the touch operation.

[0131] In the embodiment of the present application, the first sensing area 21 and the second sensing area 22 are spaced apart from each other. The distance between the first sensing area 21 and the second sensing area 22 is such that when a touch operation is performed on either sensing area, the other sensing area is not accidentally touched. For example, when a touch operation is performed on the first sensing area 21, the distance between the first sensing area 21 and the second sensing area 22 is such that the second sensing area 22 is not accidentally touched.

[0132] In an embodiment of the present application, the induction area may include special materials, such as materials that can be used for electric field coupling, materials that can be used for electromagnetic induction, and materials that produce piezoelectric effects. Materials that can be used for electric field coupling include conductive materials, such as indium tin oxide conductive layers. Electric field coupling, also known as "electrostatic coupling" or "capacitive coupling", is a coupling method caused by the existence of distributed capacitance. Coupling refers to the process of signal transmission from the first level to the second level. Generally, when not specified, it often refers to AC coupling. Electric field coupling includes the transmission of signals or energy between different nodes of a circuit through capacitance. The induction area can be made into a special conductive pattern, such as an indium tin oxide conductive pattern. Materials that can be used for electromagnetic induction include: magnetic induction coils, etc. Electromagnetic induction refers to the generation of an electromotive force by a conductor placed in a changing magnetic flux. This electromotive force is called an induced electromotive force or an induced electromotive force. If the conductor is closed into a loop, the electromotive force will drive electrons to flow, forming an induced current (induced current). Materials that produce piezoelectric effects include piezoelectric ceramics, piezoresistive films, etc.

[0133] In the following, an example is taken in which the screen protector 20 is installed on the touch screen 11 , and the first sensing area 21 corresponds to the area 111 , and the second sensing area 22 corresponds to the area 112 .

[0134] When the sensing area of ​​the screen protector 20 includes a material that can be used for electric field coupling, such as an indium tin oxide conductive layer, the screen protector 20 can be applied to a capacitive touch screen. As shown in Figure 8A, the screen protector 20 is installed on a capacitive touch screen. When a user's finger touches the first sensing area 21 on the screen protector 20, due to the human body's electric field, the user can form electric field coupling with the electrodes on the touch screen 11 through the first sensing area 21, such as forming electric field coupling with the electrodes in area 111 on the touch screen 11, generating an electric field coupling line. The dotted line in Figure 8A is the electric field coupling line. Because the first sensing area 21 of the screen protector 20 includes a material that can be used to generate electric field coupling, the first sensing area 21 can sense the electric field coupling line and thereby obtain a sensing signal (electric field coupling signal). The conductive component 23 transmits the sensing signal to the second sensing area 22. The second sensing area 22 can couple the received sensing signal to its corresponding area 112, so that area 112 can receive the sensing signal and then trigger area 112 to generate preset touch data. Therefore, capacitance changes can be detected in both area 111 and area 112. Please refer to Table 1, which exemplifies the capacitance data of the touch screen 11.

[0135] Table 1

[0136] As shown in Table 1, the capacitance values ​​corresponding to region 111 are 980, 1600, 890, 459, 1000, and 500, respectively. The capacitance value corresponding to region 112 is 900.

[0137] It can be understood that when processing data, a threshold can be set. When the capacitance value is less than the threshold, the capacitance value is uniformly set to 0. For example, if the threshold is set to 100, the capacitance values ​​less than 100 in Table 1 are all set to 0.

[0138] When the sensing area of ​​the screen protector 20 includes a material capable of generating an electromagnetic effect, such as a magnetic induction coil, the screen protector 20 can be used in an electromagnetic touch screen. As shown in FIG8B , the screen protector 20 is mounted on an electromagnetic touch screen. When a user operates a stylus 30 to touch the first sensing area 21 of the screen protector 20, the stylus 30 emits an electromagnetic signal. The electromagnetic induction plate behind the touch screen senses the electromagnetic signal from the stylus 30, causing the induction lines below the electromagnetic induction plate to change, generating a magnetic field in the electromagnetic touch screen. Because the first sensing area 21 of the screen protector 20 includes a material capable of generating an electromagnetic effect, the first sensing area 21 can sense the magnetic field and the electromagnetic signal from the stylus 20, thereby generating an induction signal (magnetic field signal). The conductive component 23 transmits the induction signal to the second sensing area 22. The second sensing area 22 can couple the received induction signal to its corresponding area 112. The area 112 on the touch screen 11 then receives the induction signal, triggering the area 112 to generate the preset touch data. Thus, changes in magnetic flux can be detected in both regions 111 and 112 .

[0139] When the sensing area of ​​screen protector 20 includes a material capable of generating a piezoelectric effect, such as a piezoresistive film, screen protector 20 can be used in resistive touch screens. As shown in FIG8C , screen protector 20 is mounted on a resistive touch screen. When a user touches first sensing area 21 of screen protector 20 and, through screen protector 20, touches the resistive touch screen, both screen protector 20 and touch screen 11 are deformed by an external force. The resistance corresponding to area 111 on touch screen 11 changes. Because the first sensing area includes a material capable of generating a piezoelectric effect, the first sensing area 21 can generate a corresponding charge based on the direct piezoelectric effect, thereby generating a sensing signal. Conductive component 23 transmits the sensing signal generated by the first sensing area 21 in response to the touch operation to the second sensing area 22. Based on the inverse piezoelectric effect, the second sensing area 22 deforms in response to the received sensing signal, generating an external force on the corresponding area 112. This force then acts on area 112 on touch screen 11, causing the resistance of area 112 to change. Thus, resistance changes can be detected in both the region 111 and the region 112 .

[0140] In the embodiment of the present application, the length of the conductive component 23 is set to prevent the user from accidentally touching another sensing area when touching any sensing area. For example, the length of the conductive component 23 is to ensure that when the user touches the first sensing area 21, the second sensing area 22 corresponding to the first sensing area 21 will not be touched due to the user's operation of touching the first sensing area 21, unless the user touches the first sensing area 21 and the second sensing area 22 simultaneously with both hands. For another example, when the screen protector 20 includes multiple groups of sensing units 200, the length and position of the conductive component 23 are set to ensure that when the user touches the first sensing area 21, the second sensing area 22 corresponding to the first sensing area 21 and any other sensing areas of the sensing units 200 will not be touched due to the user's operation of touching the first sensing area 21.

[0141] In the embodiment of the present application, the length of each conductive component 23 in any sensing unit 200 is greater than a preset length, and the width of the conductive component 23 is less than the smallest side length of the first sensing area 21 and the second sensing area 22 in the sensing unit 200. The preset length is used to indicate the length occupied by a finger when touching the touch screen 11.

[0142] For example, the length occupied by the user's finger when touching the touch screen 11 can be statistically collected, and the maximum value can be taken as the preset length. For another example, if the first sensing area 21 and the second sensing area 22 of the sensing unit 200 are both square, and the side length of the second sensing area 22 is 4 mm, and the side length of the first sensing area 21 is 1 mm, then the width of the conductive component 23 is less than 1 mm.

[0143] The preset length can be 20 mm, 25 mm, or 28 mm, etc., and can be set according to actual conditions, and this application does not impose any specific restrictions on this. The width of the conductive component 23 can be 0.1 mm, 0.2 mm, or 0.3 mm, and can be set according to actual conditions, such as the material, size, and area of ​​the sensing area, and this embodiment of the application does not impose any specific restrictions on this.

[0144] The conductive component 23 can be a wire, a coil, etc., which is not specifically limited in this application.

[0145] It is understandable that the manufacturing and materials of the sensing area on the screen protector 20 can be adapted and modified according to the touch mode of the touch screen actually used, and this application does not make any specific restrictions on this.

[0146] In the embodiment of the present application, when setting the sensing area on the screen protector 20, it is necessary to consider that it is easy for the user to touch (such as clicking or sliding, etc.), and it is also necessary to consider that it cannot cause accidental touches during the user's touch process and cannot affect the normal touch effect. In view of this, the first sensing area 21 and the second sensing area 22 on the same screen protector 20 can be set to different sizes, such as different areas and / or sizes. Among them, the smaller sensing area can be placed in a position that is not easily touched by the user, such as the edge area or near the four corners of the screen protector 20, that is, corresponding to the edge area or near the four corners of the touch screen 11. The larger sensing area is placed in an area that is easy for the user to touch, so that the electronic device 10 can be triggered to detect the presence of the screen protector 20 more promptly without the user noticing. For example, the larger sensing area can be placed at the edge of the screen protector 20 and in an area that is easy for the user to touch, that is, corresponding to the edge of the touch screen 11 and in an area that is easy for the user to touch.

[0147] In the embodiment of the present application, the first sensing region 21 and the second sensing region 22 have different sizes, such as different areas and / or dimensions. The first sensing region 21 being larger than the second sensing region 22 may include: as shown in FIG6 , the area of ​​the first sensing region 21 is larger than the second sensing region 22; as shown in FIG7 , the size of the first sensing region 21 is larger than the second sensing region 22.

[0148] In some other embodiments, the second sensing region 22 is larger than the first sensing region 21 , for example, the area and / or size of the second sensing region 22 is larger than the first sensing region 21 .

[0149] In the embodiment of the present application, the first sensing region 21 and the second sensing region 22 are both less than or equal to a first area and greater than or equal to one-quarter of the first area. The first area is the area of ​​a sensing module on the touch screen 11. A sensing module is used to generate one or more capacitance values. Preferably, a sensing module is used to generate one capacitance value.

[0150] For example, if a sensing module is 4*4 mm, the first sensing area 21 can be set to 4*4 mm, the second sensing area 22 can be set to 1*1 mm, and the length of the conductive component 23 can be 25 mm and the width can be 0.1 mm.

[0151] In other embodiments, the area of ​​any sensing area of ​​any sensing unit 200 on the same screen protector 20 is larger than the first area, and the area of ​​the remaining sensing areas is smaller than the first area. For example, when there are two or more second sensing areas 22 connected to one first sensing area 21, the area of ​​the first sensing area 21 is larger than the first area, and the areas of the remaining second sensing areas 22 are all smaller than the first area.

[0152] In some other embodiments, the area of ​​any sensing region of any sensing unit 200 on the same screen protector 20 is larger than the first area.

[0153] In other embodiments, the first sensing area 21 and the second sensing area 22 on the same screen protector 20 are of the same size, such as the same area and / or size.

[0154] The structure of the sensing unit 200 is described below by taking the example that the first sensing area 21 is larger than the second sensing area 22 in the sensing unit 200 .

[0155] As shown in FIG9A , the first sensing area 21 may be a 6*6 mm square, the second sensing area 22 may be a 2*2 mm square, the length of the conductive component 23 may be 40 mm, and the length of the conductive component 23 may be 0.1 mm.

[0156] As shown in FIG9B , the first sensing area 21 may be a 2*6 mm rectangle, the second sensing area 22 may be a 2*2 mm square, the length of the conductive component 23 may be 30 mm, and the length of the conductive component 23 may be 0.3 mm.

[0157] As shown in FIG9C , the first sensing area 21 may be a 4*4 mm parallelogram, the second sensing area 22 may be a 2*1 mm rectangle, the length of the conductive component 23 may be 40 mm, and the length of the conductive component 23 may be 0.1 mm.

[0158] As shown in FIG9D , the first sensing area 21 may be a circle with a radius r of 2 mm, the second sensing area 22 may be a circle with a radius r of 1 mm, the length of the conductive component 23 may be 25 mm, and the length of the conductive component 23 may be 0.3 mm.

[0159] In the embodiment of the present application, the sensing area may be a rectangle, a diamond, a circle or other irregular shapes, and the present application does not make any specific limitation on this.

[0160] In the embodiment of the present application, the screen protector 20 includes two or more groups of sensing units 200 , and any group of sensing units 200 can be evenly arranged around the screen protector 20 .

[0161] In other embodiments, the screen protector 20 may be surrounded by a circle of sensing units 200, which is not specifically limited in this application. In other embodiments, the screen protector 20 may be surrounded by a circle of sensing units 200, depending on the size of the sensor area and the length of the conductive component.

[0162] As shown in FIG6 , the screen protector 20 includes two or more groups of sensing units 200 , wherein the first sensing regions 21 of each group of sensing units 200 have the same shape, size, and area, and the second sensing regions 22 of each group of sensing units 200 have the same shape, size, and area.

[0163] In other embodiments, as shown in FIG10 , the shapes / sizes / areas of the first sensing regions 21 of the sensing units 200 of each group on the screen protector 20 may be partially the same or completely different, and the shapes / sizes / areas of the second sensing regions 22 of the sensing units 200 of each group may be partially the same or completely different.

[0164] In the embodiment of the present application, the position of the sensing area on the screen protector 20 can be set according to actual conditions. For example, generally, the smaller sensing area in a group of sensing units 200 is placed in the edge area, an area with a low probability of being touched by the user, to prevent affecting the most easily touched area in the middle.

[0165] In the embodiment of the present application, the number of sensing units 200 on the screen protector 20 can be set according to actual conditions, such as the size of the sensing area and the length of the conductive component 23. This application does not make any specific restrictions on this.

[0166] As shown in FIG. 11A , the screen protector 20 includes two groups of sensing units 200 . Each group of sensing units 200 includes a first sensing area 21 , a second sensing area 22 , and a conductive component 23 for connecting the first sensing area 21 and the second sensing area 22 .

[0167] In other embodiments, a group of sensing units 200 may include a first sensing region 21, N second sensing regions 22, and N conductive components 23 for connecting the first sensing region 21 and the N second sensing regions 22. N is an integer greater than or equal to 2.

[0168] Taking N as 2 as an example, as shown in FIG11B , the screen protector 20 includes two groups of sensing units 200 , and each sensing unit 200 includes a sensing area 21 , two second sensing areas 22 ( 22 a , 22 b ) and two conductive components 23 ( 23 a , 23 b ).

[0169] In the embodiment of the present application, the screen protector 20 can be classified into types according to its use, such as screen protector (screen film) and body protector (body film). The screen protector 20 can also be classified into types according to its function, such as privacy protector, screen scratch protector, body scratch protector, and body decoration protector. The privacy protector can be a privacy film. The screen scratch protector can be a tempered film, etc.

[0170] In the embodiment of the present application, corresponding sensing units 200 can be provided according to different types of screen protectors, and thus different types of screen protectors can be distinguished according to the sensing units 200.

[0171] For example, different types of screen protectors 20 can be distinguished by the number of first sensing values ​​in the preset touch data triggered and generated by the sensing unit 200. The first sensing value is a sensing value in the touch data that is greater than a first threshold. The first sensing value will be described in detail below.

[0172] Specifically, the sizes of the first sensing area 21 and the second sensing area 22 in the sensing unit 200 can be set so that the number of first sensing values ​​in the preset touch data generated by triggering the touch screen 11 is a preset number. For example, when the number of first sensing values ​​is 1, the corresponding type of screen protector 20 is a tempered glass film. When the number of first sensing values ​​is 2, the corresponding type of screen protector 20 is a privacy film.

[0173] For example, taking a sensing module measuring 4*4mm, with the first sensing area 21 corresponding to area 111 of the touch screen 11 and the second sensing area 22 corresponding to area 112, the sizes of the first sensing area 21 and the second sensing area 22 on the tempered film can be set to be less than or equal to 4*4mm. This allows, when the tempered film is mounted on the touch screen 11, a user touches the first sensing area 21 of the tempered film, and the sensing signal transmitted by the second sensing area 22 triggers area 112 to generate preset touch data, in which the number of first sensing values ​​in the preset touch data is 1. Alternatively, the first sensing area 21 of the privacy film can be set to 16*16mm, and the second sensing area 22 can be set to 8*8mm. This allows, when the tempered film is mounted on the touch screen 11, a user touches the first sensing area 21 of the tempered film, and the sensing signal transmitted by the second sensing area 22 triggers area 112 to generate preset touch data, in which the number of first sensing values ​​in the preset touch data is 2.

[0174] For another example, different types of screen protectors 20 can be distinguished by the number of first sensing areas 21 (or second sensing areas 22) in a sensing unit 200. Exemplarily, when the sensing unit 200 includes N first sensing areas 21 or N second sensing areas 22, the type of the screen protector 20 is determined to be a tempered film, where N is an integer greater than or equal to 2. As shown in FIG11B , the sensing unit 200 includes two second sensing areas 22a and 22b, and the type of the screen protector 20 shown in FIG11B is determined to be a tempered film. As another example, when the sensing unit 200 includes one first sensing area 21 or one second sensing area 22, the type of the screen protector 20 is determined to be a privacy film. As shown in FIG11A , the type of the screen protector 20 shown in FIG11A is determined to be a privacy film.

[0175] It is understandable that corresponding sensing units can be set for different screen protectors according to actual conditions, and the embodiments of the present application do not specifically limit this.

[0176] In the embodiment of the present application, the screen protector 20 may be the above-mentioned film, or a hydrogel film, etc., which is not specifically limited in the embodiment of the present application.

[0177] 12 , which illustrates an exemplary screen protector detection system 300 provided in an embodiment of the present application. The screen protector detection system 300 includes the aforementioned electronic device 10 and screen protector 20. The details of the electronic device 10 and screen protector 20 can be found above and will not be repeated here.

[0178] As shown in Figure 12, the various sensing areas and the conductive components 23 on the screen protector 20 are not visible. When the screen protector 20 is mounted on the touch screen 11, the user cannot see the various sensing areas and the conductive components 23 on the screen protector 20.

[0179] In other embodiments, the sensing area and / or the conductive component 23 on the screen protector 20 is visible, that is, the sensing area and / or the conductive component 23 on the screen protector 20 can be a visible pattern, or a visible pattern can be set at a position corresponding to the sensing area and / or the conductive component 23. The embodiments of the present application do not specifically limit this.

[0180] Please refer to Figure 13, which exemplifies the screen protector detection method provided in an embodiment of the present application. The screen protector detection method can be applied to the above-mentioned electronic device 10, and can also be applied to the above-mentioned screen protector detection system 300, and can be executed by the electronic device 10. The method includes steps S131 to S132.

[0181] Step S131 : In response to a touch operation on a first area of ​​the touch screen, target touch data of a second area of ​​the touch screen is acquired, where the first area corresponds to the second area and is spaced apart from each other.

[0182] In the embodiment of the present application, touch operations may include touch operations, click operations, long press operations, sliding operations, etc. performed by the user's fingers, and may also include touch operations, tapping operations, click operations, long press operations, sliding operations, etc. performed by the user using other parts of the body, such as knuckles. It may also include click operations, long press operations, writing operations, etc. performed by the user using an input device, such as a stylus. The embodiment of the present application does not make specific limitations on this.

[0183] For example, if a user performs a touch operation on a touch screen using a finger or knuckle, a touch operation is considered when the user's finger or knuckle moves away from the touch screen. In other words, a single click on the touch screen, a single long press on the touch screen, a single slide on the touch screen, or a single tap on the touch screen can all be considered a touch operation.

[0184] In an embodiment of the present application, a user's touch operation on the touch screen may include a touch operation performed on the touch screen by the user directly touching the touch screen, and may also include a touch operation performed on the touch screen by the user touching a screen protector through the screen protector. For example, when the screen protector is not installed on the touch screen, the user's fingers, knuckles, or other parts of the body, or the user uses an input device to directly touch the touch screen, inputting a touch operation to the touch screen. When the screen protector is installed on the touch screen, the user's fingers, knuckles, or other parts of the body, or the user uses an input device to touch the screen protector, inputting a touch operation to the screen protector. The screen protector transmits the touch operation it receives to the touch screen, and the touch operation on the screen protector is the touch operation on the touch screen.

[0185] In an embodiment of the present application, the touch operation on the first area of ​​the touch screen, that is, the touch operation of the user on the touch screen acts on the first area of ​​the touch screen. The touch operation of the user on the first area may include the touch operation performed by the user directly on the first area of ​​the touch screen, and may also include the touch operation performed by the user on the first area of ​​the touch screen through the screen protector. For example, when the screen protector is not installed on the touch screen, the user's fingers, knuckles or other parts or the user uses an input device to directly touch the first area of ​​the touch screen, and input a touch operation to the first area of ​​the touch screen. When the screen protector is installed on the touch screen, the user's fingers, knuckles or other parts or the user uses an input device to touch the area on the screen protector corresponding to the first area, the area on the screen protector corresponding to the first area transmits the received touch operation to the first area of ​​the touch screen, and the first area receives the user's touch operation.

[0186] In the embodiments of the present application, the first area and the second area are both local areas on the touch screen. The first area and the second area are separated from each other, that is, the first area and the second area are not connected. The first area and the second area have a one-to-one correspondence. When there are multiple first areas, each first area has its own unique corresponding second area, and correspondingly, each second area has its own unique corresponding first area. In other words, different first areas have different corresponding second areas, and different second areas have different corresponding first areas.

[0187] In an embodiment of the present application, the correspondence between the first area and the second area can be related to the first sensing area and the second sensing area on the screen protector. For example, taking a sensing unit comprising a first sensing area a and a second sensing area b, when the screen protector is installed on an electronic device, the first sensing area a of the screen protector corresponds to area A of the touch screen, and the second sensing area b corresponds to area B of the touch screen. Therefore, it can be determined that area A corresponds to area B. With area A corresponding to the first sensing area a being the first area, area B is the second area corresponding to the first area. As another example, taking a sensing unit comprising a first sensing area a1, a second sensing area b1, and a second sensing area b2, when the screen protector is installed on an electronic device, the first sensing area a1 of the screen protector corresponds to area A1 of the touch screen, the second sensing area b1 corresponds to area B1 of the touch screen, and the second sensing area b2 corresponds to area B2 of the touch screen. Therefore, it can be determined that area A1 corresponds to areas B1 and B2. With area A1 corresponding to the first sensing area a1 being the first area, both areas B1 and B2 are second areas corresponding to the first area.

[0188] In an embodiment of the present application, the electronic device obtains target touch data of a second area corresponding to the first area on the touch screen in response to a touch operation on the first area of ​​the touch screen. Correspondingly, the electronic device can also obtain target touch data of the first area corresponding to the second area on the touch screen in response to a touch operation on the second area of ​​the touch screen. For example, the first area A corresponds to the second area B, and the electronic device 10 obtains target touch data of the second area B on the touch screen 11 in response to a touch operation on the first area A of the touch screen 11. Correspondingly, the electronic device 10 can also obtain target touch data of the first area A on the touch screen 11 in response to a touch operation on the second area B of the touch screen 11.

[0189] In an embodiment of the present application, the electronic device may pre-store relevant information of the first area and the second area corresponding to the first area. For example, the electronic device may pre-establish a table to record the coordinates of the first area on its touch screen and the coordinates of the second area corresponding to the first area. When it is subsequently determined that the coordinates acted upon by the touch operation fall within the coordinates of the first area, the touch data corresponding to the coordinates of the second area corresponding to the first area is obtained, and the touch data corresponding to the coordinates of the second area is the target touch data. Alternatively, when it is subsequently determined that the coordinates acted upon by the touch operation fall within the coordinates of the second area, the touch data corresponding to the coordinates of the first area corresponding to the second area is obtained, and the touch data corresponding to the coordinates of the first area is the target touch data. As in the above example, the electronic device can obtain touch data on area A1 in response to a touch operation on area B1, and the touch data on area A1 is the target touch data.

[0190] In an embodiment of the present application, the coordinates of the recording area can be the coordinates on the X and Y axes of the recording touch screen, or the touch sampling points of the electrodes corresponding to the recording area. Taking Table 1 as an example, the first area includes 2*3 touch sampling points, and the 2*3 touch sampling points include: sampling points corresponding to RX1 and TX5, sampling points corresponding to RX1 and TX6, sampling points corresponding to RX1 and TX7, sampling points corresponding to RX2 and TX5, sampling points corresponding to RX2 and TX6, and sampling points corresponding to RX2 and TX7. The second area includes 1 touch sampling point, which is the sampling point corresponding to RX1 and TX1. The first area (2*3 touch sampling points) is associated with the second area (1 touch sampling point) to obtain the target touch data corresponding to the touch sampling point of the second area when it is subsequently determined that the touch operation acts on the touch sampling point corresponding to the first area, or, when it is subsequently determined that the touch operation acts on the touch sampling point corresponding to the second area, the target touch data corresponding to the touch sampling point of the first area is obtained.

[0191] In the embodiment of the present application, the touch data may include touch signals collected by touch detection components such as the touch sensor 14A, the capacitive sensor 14B, the electromagnetic sensor 14C, the pressure sensor 14D, the piezoelectric sensor or the piezoresistive sensor.

[0192] In other embodiments, the touch data may include data obtained after preprocessing the touch signal collected by the touch detection component. The preprocessing may include but is not limited to: setting the capacitance value smaller than the threshold to 0 as described above.

[0193] In this embodiment of the present application, the touch data for each area of ​​the touch screen includes a corresponding sensing value, and the acquired target touch data also includes its corresponding sensing value. As shown in Table 1, the touch data for the first area is the touch data collected by the aforementioned 2*3 touch sampling points, with capacitance values ​​of 980, 1600, 890, 459, 100, and 500, respectively. The target touch data for the second area is the touch data collected by the touch sampling points corresponding to RX1 and TX1. The sensing value of the target touch data for the second area is the capacitance value of 900 corresponding to RX1 and TX1.

[0194] In an embodiment of the present application, the electronic device can directly obtain target touch data of a second area in response to a touch operation on a first area of ​​the touch screen.

[0195] In other embodiments, the electronic device may obtain touch data of the touch screen in response to a touch operation on a first area of ​​the touch screen, where the touch data includes touch data of all areas, and then obtain target touch data of a second area from the touch data of the touch screen.

[0196] Step S132 : determining the relationship between the electronic device and the screen protector according to the target touch data, where the relationship includes whether the electronic device is installed with a screen protector or not.

[0197] In an embodiment of the present application, the screen protector includes at least one set of sensing units, each comprising a first sensing area, a second sensing area, and a conductive component connecting the first and second sensing areas. When the screen protector is mounted on a touch screen, the first sensing area corresponds to the first area and receives a sensing signal based on a touch operation on the first area. The second sensing area corresponds to the second area, and the conductive component transmits the sensing signal to the second sensing area, which triggers the second area to generate predetermined touch data.

[0198] It is understood that the first sensing area may also correspond to the second area, and the second sensing area may correspond to the first area. This application does not specifically limit this. The following description takes the first sensing area corresponding to the first area and the second sensing area corresponding to the second area as an example.

[0199] In an embodiment of the present application, when a screen protector is installed on a touch screen, a user touches the first sensing area of ​​the screen protector, and the first area on the touch screen also receives the user's touch operation. The touch screen generates touch data for the first area based on the touch operation on the first area. Simultaneously, the first sensing area receives a sensing signal based on the touch operation on the first area and transmits the sensing signal to the second sensing area via a conductive component. The sensing signal received by the second sensing area can be used to trigger the second area to generate predetermined touch data.

[0200] As shown in Figure 8A , when the screen protector 20 is installed on a capacitive touch screen, the sensing signal received by the second sensing area 22 is an electric field coupling signal. As shown in Figure 8B , when the screen protector 20 is installed on an electromagnetic touch screen, the sensing signal received by the second sensing area 22 is a magnetic field signal. As shown in Figure 8C , when the screen protector 20 is installed on a resistive touch screen, the sensing signal received by the second sensing area 22 is an electrical signal.

[0201] It can be understood that when the screen protector is installed on the touch screen, the user touches the first sensing area of ​​the screen protector, and the second area can generate preset touch data. When the screen protector is not installed on the touch screen, the user touches the second sensing area of ​​the screen protector, and the second area does not generate preset touch data. Therefore, it can be determined whether the target touch data obtained in the second area is the preset touch data. If so, it can be determined that the screen protector is installed on the touch screen. If not, it can be determined that the screen protector is not installed on the touch screen.

[0202] Specifically, when the screen protector is installed on a touch screen, a user performs a touch operation on the first sensing area of ​​the screen protector. The first area on the touch screen can receive the touch operation through the first sensing area, and the touch screen can generate touch data for the first area based on the touch operation on the first area. The second area can generate preset touch data based on the sensing signal. The preset touch data generated by the second area is the touch data generated by the second area on the touch screen based on the sensing signal from the second sensing area on the screen protector, and is not the touch data generated directly by the second area on the touch screen based on the user's touch operation. When the screen protector is not installed on the touch screen, a user performs a touch operation on the first sensing area of ​​the screen protector. The first area on the touch screen can receive the touch operation through the first sensing area, and the touch screen can generate touch data for the first area based on the touch operation on the first area. If the second area does not receive the user's touch operation, it does not generate touch data. The second area also does not receive the sensing signal transmitted by the second sensing area on the screen protector, and therefore does not generate preset touch data.

[0203] It is understood that when the screen protector is installed on the touch screen, the user touches the second sensing area of ​​the screen protector, and the first area can generate preset touch data. When the screen protector is not installed on the touch screen, the user touches the second sensing area of ​​the screen protector, and the first area does not generate preset touch data.

[0204] In the embodiment of the present application, the preset touch data is touch data that meets a preset condition, and the preset condition is related to the size or area of ​​the first sensing area and the second sensing area.

[0205] In an embodiment of the present application, the preset condition includes: the number of first sensing values ​​in the touch data is a first preset number, wherein the first sensing value is a sensing value greater than a first threshold, and the first preset number is set according to the size or area of ​​the first sensing area and the second sensing area.

[0206] The first threshold is used to determine whether the first sensing value has a signal. When the sensing value is greater than the first threshold, it can be determined that the touch sampling point corresponding to the sensing value has a signal, that is, the touch data at the touch sampling point has an initial value. When the sensing value is less than or equal to the first threshold, it can be determined that the touch sampling point corresponding to the sensing value has no signal, that is, the touch data at the touch sampling point has no initial value.

[0207] The first threshold value can be set according to actual conditions. For example, if the touch screen is a capacitive touch screen, the first threshold value can be 100, 200, 300 or 400, etc. This application does not make any specific limitation on this.

[0208] In an embodiment of the present application, the first preset number is set based on the size or area of ​​the first sensing area, the second sensing area, and the sensing module. For example, when the touch screen is a capacitive touch screen, and one sensing module is used to generate one capacitance value, the first sensing area and the second sensing area can be set to be less than or equal to the first area and greater than or equal to one-quarter of the first area. This can limit the first sensing value of the generated preset touch data to a single capacitance value, i.e., there is only one first sensing value, thereby limiting the number of first sensing values ​​in the generated preset touch data.

[0209] When a first region corresponds to only one second region, the first preset number can be the number of first sensing values ​​in the unique corresponding second region. When a first region corresponds to N second regions, the first preset number can be the total number of first sensing values ​​in the N second regions, or the number of first sensing values ​​in each second region. The first preset number can be 1, 2, or 3, and can be set based on actual circumstances, and this application does not impose specific limitations on this.

[0210] Specifically, step S132 of determining the relationship between the electronic device and the screen protector based on the target touch data includes: when the target touch data belongs to preset target touch data, that is, when the target touch data is touch data that meets preset conditions, determining that the relationship between the electronic device and the screen protector is that the electronic device is installed with a screen protector. When the target touch data does not belong to the preset target touch data, that is, when the target touch data is not touch data that meets the preset conditions, determining that the relationship between the electronic device and the screen protector is that the electronic device is not installed with a screen protector.

[0211] When the target touch data meets the above preset conditions, the target touch data belongs to the preset target touch data. When the target touch data does not meet the above preset conditions, the target touch data does not belong to the preset target touch data.

[0212] Taking the first threshold value of 300 and the first preset number of 1 as an example, as shown in Table 1, in response to a touch operation on the first area, target touch data for the second area is obtained. The target touch data is the capacitance value 900 corresponding to RX1 and TX1. Based on the fact that the capacitance value 900 of the second area is greater than 300, and only one capacitance value 900 is greater than 300, it can be determined that the electronic device is equipped with a screen protector.

[0213] Referring to FIG. 14 , another screen protector detection method provided in an embodiment of the present application is exemplarily described. This screen protector detection method can be applied to the aforementioned electronic device 10 or the aforementioned screen protector detection system 300. The method can be executed by the electronic device 10 and includes steps S141 to S145.

[0214] Step S141: detecting a first operation on the touch screen and acquiring touch data to be processed.

[0215] In the embodiment of the present application, the user's first operation on the touch screen may include a touch operation, a click operation, a long press operation, a sliding operation, etc. performed by the user's fingers on the touch screen, and may also include the user using other parts of the body, such as knuckles, to touch the touch screen, to tap, click, long press operation, sliding operation, etc., and may also include the user using an input device, such as a stylus, to touch, click, long press operation, writing operation, etc. on the touch screen. The embodiment of the present application does not make any specific limitations on this.

[0216] For example, a user performs a first operation on the touch screen using a finger or knuckle. The first operation occurs from the time the user's finger or knuckle touches the touch screen to the time the finger or knuckle leaves the touch screen. In other words, a single click on the touch screen, a single long press on the touch screen, a single slide on the touch screen, or a single tap on the touch screen 1 can all be considered a first operation.

[0217] In the embodiment of the present application, the touch screen may include but is not limited to: a touch screen using capacitive touch technology, a touch screen using electromagnetic induction (EMR) technology, a touch screen using the piezoresistive effect, etc., and the present application does not make specific limitations on this.

[0218] In an embodiment of the present application, the electronic device detects a first operation on the touch screen and obtains touch data to be processed of the touch screen. The touch data to be processed may include touch data of various areas on the touch screen.

[0219] The following uses a capacitive touch screen as an example.

[0220] The surface of a capacitive touchscreen is coated with a layer of conductive material, which forms a capacitive field. When a user touches the touchscreen, the capacitive field is disturbed and changes. The touchscreen can include multiple touch sampling points for sampling capacitance values. These touch sampling points can be distributed across the capacitive touchscreen in a grid-like pattern. Capacitive touchscreens sample the capacitance values ​​of each touch sampling point at a specific frequency to obtain capacitance data for each area of ​​the capacitive touchscreen. This capacitance data for each area of ​​the capacitive touchscreen serves as the touch data to be processed.

[0221] Generally speaking, regardless of whether the user is touching the touch screen, the touch screen sampling action can continue at a specific frequency. For example, when the touch screen is in the on state, the electronic device can sample the capacitance value of each touch sampling point at a higher touch sampling rate, such as 120Hz, 240Hz, 360Hz, 480Hz, or even higher sampling rate. When the electronic device is in the off state, the electronic device uses a lower touch sampling rate to reduce power consumption.

[0222] Each time the touch screen is sampled, a frame of capacitance data is generated. This capacitance data is also called raw capacitance data. Raw capacitance data is also the touch data to be processed. A frame of raw capacitance data can include the capacitance values ​​of each touch sampling point on the touch screen.

[0223] The touch screen can report the raw capacitance data to the touch screen driver in the core layer of the electronic device. The touch screen driver can then provide the received raw capacitance data to the corresponding module in the electronic device's system that processes input events to calculate the coordinates of the touch point. Generally speaking, the touch point can be the touch sampling point where the capacitance value of the touch screen changes the most during the user's touch operation.

[0224] When a person touches the screen (assuming the touch point is contact A), the values ​​of several capacitance feature points around contact A will change. For example, the capacitance values ​​of some of the m×n continuous capacitance feature points including contact A are likely to increase significantly after the user touches the touch screen. It should be noted here that among the above m×n continuous capacitance feature points, not all capacitance feature points will necessarily increase. Whether the capacitance value of each capacitance feature point changes, and the degree of change in the capacitance value, mainly depend on the distance between the capacitance feature point and contact A. Generally speaking, the capacitance value of the capacitance feature point where contact A is located changes the most. With contact A as the center, the capacitance value of the capacitance feature point farther away from contact A changes less.

[0225] Please refer to Table 1. The (2×3) capacitance characteristic points in TX5 to TX8 and RX1 to RX2 can be understood as the contact area. Among them, the points corresponding to TX6 and RX1 are the contact points.

[0226] In some embodiments, the electronic device may obtain a set of capacitance data (i.e., touch data to be processed) in response to a user's touch operation or first operation on the touch screen. The electronic device may store the obtained capacitance data in a random access memory (RAM), for example, in the form of a cache in the RAM, or may store the obtained capacitance data in a flash memory, which is not limited in the embodiments of the present application.

[0227] It is understandable that since the touch sampling rate of the touch screen is usually tens to hundreds of Hz, during each touch operation of the user, the touch screen usually samples the capacitance value of each touch sampling point multiple times, and each touch sampling will obtain a frame of capacitance data.

[0228] In an embodiment of the present application, the touch data to be processed includes the sensing value of the touch screen. The sensing value of the touch screen can be used to indicate touch information of the first operation, such as the touch point of the first operation. When the touch screen is a touch screen using capacitive touch technology, the sensing value obtained in the touch data to be processed can be a capacitance value. When the touch screen is a touch screen using electromagnetic induction technology, the sensing value obtained in the touch data to be processed can be a magnetic flux. When the touch screen is a touch screen implemented using the piezoresistive effect, the sensing value obtained in the touch data to be processed can be a voltage value or a current value.

[0229] Step S142: determining first touch data in the touch data to be processed that meets a touch condition, the touch condition including that the number of second sensing values ​​in the touch data is a second preset number, the areas on the touch screen corresponding to the second sensing values ​​are continuous, and the second sensing values ​​are sensing values ​​greater than a second threshold.

[0230] In the embodiment of the present application, the touch condition includes a finger touch condition and / or a stylus touch condition. The finger touch condition is the touch condition corresponding to a user operating the touch screen with a finger. The stylus touch condition is the touch condition corresponding to a user operating the touch screen with a stylus.

[0231] In some embodiments, the finger touch condition may be a touch condition corresponding to a user operating the touch screen through a human body part such as a finger or a knuckle.

[0232] In an embodiment of the present application, the second preset number is greater than the first preset number. The number of first sensing values ​​in the touch data generated by the touch screen in response to a touch operation is greater than the number of first sensing values ​​in the preset touch data generated by the touch screen in response to the sensing signal. The number of second sensing values ​​in the touch data generated by the touch screen in response to the touch operation is greater than the number of first sensing values ​​in the preset touch data generated by the touch screen in response to the sensing signal.

[0233] In an embodiment of the present application, the second threshold value in the finger touch condition is smaller than the second threshold value in the stylus touch condition. The second preset number in the finger touch condition is larger than the second preset number in the stylus touch condition.

[0234] In an embodiment of the present application, the electronic device may determine a corresponding touch condition according to the type of the touch screen. For example, when the touch screen is an electromagnetic touch screen, the touch condition may be determined to be a stylus touch condition.

[0235] In the embodiments of the present application, the first threshold and the second threshold may be the same or different. When the user operates the touch screen using a finger, knuckle, or other human body part, the first threshold and the second threshold may be the same. When the touch screen is operated using a stylus, the first threshold and the second threshold may be different, and the second threshold may be greater than the first threshold.

[0236] In the embodiment of the present application, when the touch data corresponding to the first operation meets the touch condition, such as determining that touch data meeting the touch condition exists in the touch data to be processed, the first operation is determined to be a touch operation.

[0237] Step S143 : when the area corresponding to the first touch data is the first area, determining that the first operation is a touch operation on the first area.

[0238] The first touch data that meets the touch condition corresponds to the first area, that is, the first touch data is touch data of the first area. In other words, if the touch data of the first area meets the touch condition, the first operation is a touch operation on the first area.

[0239] Step S144 : acquiring target touch data of a second area of ​​the touch screen in response to the touch operation on the first area of ​​the touch screen.

[0240] The relevant content of step S144 can refer to the above step S131 and will not be repeated here.

[0241] Step S145 : determining the relationship between the electronic device and the screen protector according to the target touch data, where the relationship includes whether the electronic device is installed with a screen protector or not.

[0242] In an embodiment of the present application, determining the relationship between the electronic device and the screen saver based on the target touch data includes: when the second preset number is greater than the number of first sensing values ​​in the target touch data, i.e., the touch data for the first area is generated based on a user's touch operation, while the touch data for the second area is not generated based on the user's touch operation, and thus the relationship between the electronic device and the screen saver can be determined based on the target touch data. When the second preset number is less than or equal to the number of first sensing values, i.e., the user may have simultaneously performed touch operations on the first area and the second area, and the relationship between the electronic device and the screen saver is not determined.

[0243] In the embodiment of the present application, when the user performs touch operations on the first sensing area and the second sensing area at the same time, in order to avoid misjudgment, the screen protector is not detected.

[0244] Referring to FIG. 15 , another screen saver detection method provided in an embodiment of the present application is exemplarily described. This screen saver detection method can be applied to the aforementioned electronic device 10 or the aforementioned screen saver detection system 300. The method can be executed by the electronic device 10 and includes steps S151 to S159.

[0245] Step S151: detecting a first operation on the touch screen and acquiring touch data to be processed.

[0246] The relevant content of step S151 can refer to the above step S141 and will not be repeated here.

[0247] Step S152 , determining whether there is a starting value in the first area or the second area of ​​the touch screen according to the touch data to be processed.

[0248] If not, execute step S153; if so, execute step S154.

[0249] In an embodiment of the present application, the electronic device may pre-store the coordinates corresponding to the first area and the second area. When the screen protector includes multiple sensing units, the coordinates of the area on the touch screen corresponding to each sensing area of ​​all sensing units may be stored. When there are multiple different types of screen protectors, the coordinates of the area on the touch screen corresponding to all sensing areas of all screen protectors may be stored.

[0250] In the embodiment of the present application, the electronic device determines whether the touch data to be processed falls within the stored coordinates of the first area or the second area based on the pre-stored coordinates of the first area and the second area.

[0251] In an embodiment of the present application, when a user uses an electronic device, the user will touch the touch screen of the electronic device, such as when the user's finger touches the electronic device. The touch screen of the electronic device will receive a touch signal. If the touch screen is a capacitive touch screen, the capacitance value (i.e., the touch data to be processed) is obtained on the mobile phone. According to the capacitance value, it is determined whether there is a starting value at the position of the pre-stored first area or the second area, that is, whether the sensing value on the first area or the second area is greater than the first threshold. If it is greater than or equal to the first threshold, it is considered that there is a starting value. If it is less than the first threshold, it is considered that there is no starting value.

[0252] For example, taking Table 1 as an example, the first threshold is 300, and the capacitance values ​​of the first region are 980, 1600, 890, 459, 1000, and 500, respectively. The capacitance values ​​of the first region are all greater than the first threshold of 300, so the first region has a starting value. The capacitance value of the second region is 900, which is also greater than the first threshold of 300, so the second region has a starting value.

[0253] Step S153, ending the screen protector detection process.

[0254] If there is no starting value in either the first area or the second area stored in the electronic device, the screen saver detection process ends and no determination is made whether the electronic device is equipped with a screen saver. When a user operation on the touch screen is detected next time, steps S151 and S152 may be continued to determine whether to perform the screen saver detection process.

[0255] When the user's first operation is performed on an area other than the first area and the second area on the touch screen, there is no value stored in the first area or the second area of ​​the electronic device. Since the user did not perform a touch operation on the first area or the second area, in order to avoid misjudgment, the screen protector detection process is ended.

[0256] Step S154 , determining whether the first operation is a touch operation on the first area.

[0257] In this embodiment of the present application, after determining in step S152 that the first or second area of ​​the touch screen has a starting value, the electronic device determines whether the touch data with the starting value meets the touch condition. If so, it determines whether the touch data meeting the touch condition corresponds to the first area. If so, it determines that the first operation is a touch operation on the first area. If it is determined that all touch data with the starting value do not meet the touch condition, the screen saver detection process ends.

[0258] When all the touch data with starting values ​​do not meet the touch condition, that is, the user's first operation is not a touch operation that meets the touch condition, the screen saver detection process ends.

[0259] For example, taking the second threshold as 800 and the first preset number as 3 as an example, when there is a starting value in the first area or the second area, it is determined whether the position corresponding to the first area is a touch operation. When the capacitance value of the first area is greater than the second threshold 800 and the number of capacitance values ​​greater than the second threshold is greater than 3, it is determined that the operation on the first area is a touch operation.

[0260] If yes, go to step S155; if no, go to step S158.

[0261] Step S155 , determining whether the target touch data of the second area is the preset touch data.

[0262] In the embodiment of the present application, when it is determined that the first operation is a touch operation on the first area after executing step S154, target touch data of a second area corresponding to the first area is obtained to determine whether the target touch data of the second area is preset touch data.

[0263] For details on determining whether the target touch data of the second area is the preset touch data, reference may be made to the above step S132 , which will not be described in detail here.

[0264] If yes, go to step S156; if no, go to step S157.

[0265] Step S156: Determine whether the electronic device is equipped with a screen protector.

[0266] Step S157: determining that the electronic device is not equipped with a screen protector.

[0267] In the embodiment of the present application, when it is determined that the user has performed a touch operation on the first area, it is determined whether the touch data on the second area corresponding to the first area meets the preset conditions. If so, it indicates that the user has installed a screen protector, and the screen is in the film-applied state. If not, such as if the second area has no starting value or the starting value of the second area is a starting value of another type, the preset conditions are not met, indicating that the user has not installed a screen protector, and the screen is in the non-film-applied state.

[0268] Step S158 , determining whether the first operation is a touch operation on the second area.

[0269] In the embodiment of the present application, after it is determined in step S154 that the first operation is not a touch operation on the first area, it is possible to continue to determine whether the first operation is a touch operation on the second area.

[0270] If yes, go to step S159; if no, go to step S153.

[0271] In the embodiment of the present application, after step S158 , if it is determined that the first operation is neither a touch operation on the first area nor a touch operation on the second area, the screen saver detection process may be terminated.

[0272] Step S159 , determining whether the target touch data of the first area is the preset touch data.

[0273] In the embodiment of the present application, after executing step S158 to determine that the first operation is a touch operation on the second area, target touch data of the first area corresponding to the second area is obtained to determine whether the target touch data of the first area is preset touch data.

[0274] For details on determining whether the target touch data of the first area is the preset touch data, reference may be made to the above-mentioned step S132 , which will not be described in detail herein.

[0275] If yes, go to step S156; if no, go to step S157.

[0276] In an embodiment of the present application, if the touch data of the first area does not meet the touch condition or the preset condition, the touch data of the first area may be a signal state caused by other noise. At this time, in the noise state, to prevent misjudgment, no statistical judgment is performed on the film state, and the screen protector detection process is ended.

[0277] After determining that a screen protector is installed on an electronic device, refer to FIG16 , which illustrates another screen protector detection method provided in an embodiment of the present application. This screen protector detection method can be applied to the electronic device 10 described above, as well as to the screen protector detection system 300 described above. The method can be executed by the electronic device 10 and includes steps S161 and S162.

[0278] Step S161 : When it is determined that the electronic device is equipped with a screen protector, the type of the screen protector is determined.

[0279] In an embodiment of the present application, the electronic device can determine the type of screen protector based on the number of first sensing values ​​in the target touch data, and / or determine the type of screen protector based on the number of areas, where the number of areas is the number of second areas corresponding to the first area.

[0280] Step S162: adjusting the functional mode of the touch screen to match the type of the screen protector, the functional mode including one or more of the following: touch sensitivity, display brightness, display color, and display of handwriting.

[0281] In the embodiment of the present application, the functional modes of the touch screen may include but are not limited to: a touch mode, a display mode, a writing mode, and a tap recognition mode of the touch screen.

[0282] After the touch screen is installed with a screen protector, for example, the touch sensitivity, display brightness, display color of the touch screen, and touch operations on the touch screen, the touch screen's tap recognition ability, and the display of written notes with a stylus will be affected. In order to ensure the use effect of the electronic device's touch screen in various functional modes, this application can pre-set the functional mode of the touch screen with the screen protector installed, for example, adjust the touch mode, display mode, writing mode, and tap recognition mode to match the functional mode with the screen protector, so as to compensate for the impact of the screen protector on the touch screen function and ensure the use effect of the touch screen in various functional modes.

[0283] Specifically, taking touch sensitivity as an example, the electronic device can pre-store a lower value (for example, 0x04, the larger the register value, the lower the sensitivity, and the smaller the pressure + value) than the original value (for example, the original register value is 0x05, and the corresponding pressure value is 80) in the touch screen sensitivity register, so that the sensitivity difference can be adjusted. Similarly, if the average value is greater than the original value, a larger value is written to the register until the difference between the average pressure value and the original value is within the set range. After confirming that the screen protector is installed, the corresponding value is obtained from the touch screen sensitivity register, and the touch sensitivity of the touch screen is adjusted to the corresponding parameter value that matches the installation of the screen protector.

[0284] In an embodiment of the present application, after the functional mode of the touch screen is adjusted to match the type of the screen protector, the adjusted functional mode of the touch screen is saved until it is detected that another different type of screen protector is installed on the electronic device.

[0285] In an embodiment of the present application, the electronic device can pre-set the functional mode of the corresponding touch screen for each type of screen protector. The electronic device stores each type of screen protector and its corresponding functional mode of the touch screen. For example, the tempered film and its corresponding functional mode are stored as A, and the anti-peep film and its corresponding functional mode are stored as B. Functional mode A includes one or more parameter setting values ​​such as touch sensitivity, display brightness, display color, and display of handwriting. Functional mode B includes one or more parameter setting values ​​such as touch sensitivity, display brightness, display color, and display of handwriting. The setting values ​​of each parameter in functional mode A and functional mode B may be different or partially the same.

[0286] In an embodiment of the present application, the electronic device can also display corresponding guidance graphics to guide the user to actively trigger the electronic device to detect the screen protector, and then actively adjust the functional mode of the touch screen to match the type of screen protector.

[0287] In an embodiment of the present application, the electronic device displays a guide graphic in response to the second operation, where the guide graphic is used to indicate the positions of the first area and the second area, and the second operation is used to instruct to perform a screen protector detection.

[0288] The second operation may include but is not limited to the above-mentioned touch operation, and may also be an operation on a button of the electronic device such as a volume button, or may be voice input, which is not specifically limited in the embodiment of the present application.

[0289] For example, the electronic device may provide a detection control for detecting a screen protector, and when the user opens the detection control, the electronic device receives the second operation.

[0290] In some embodiments, the second operation may also be used to indicate the type of screen protector being detected.

[0291] For example, an electronic device may provide different types of screen protector detection controls, such as control 1 for instructing the electronic device to detect the presence of a tempered glass film, and control 2 for instructing the electronic device to detect the presence of a privacy film. When the user turns on control 1, the electronic device receives a second operation, which instructs the electronic device to detect the presence of a tempered glass film, that is, the type of screen protector to be detected.

[0292] In an embodiment of the present application, different screen saver types correspond to different guide graphics. Displaying the guide graphics on the electronic device may include: obtaining the type of screen saver to be detected, displaying a guide graphic corresponding to the type of screen saver, wherein the corresponding guide graphic is used to indicate the positions of the first area and the second area corresponding to the type of screen saver.

[0293] For example, the electronic device may provide a detection control for detecting a screen saver. When the user opens the detection control, the electronic device may display a guidance interface 170 as shown in FIG17A . In FIG17A , guidance interface 170 includes a guidance graphic 171 for indicating the location of the first area, a guidance graphic 172 for instructing the user to touch the location of the first area, and a guidance frame 173 , wherein the text "Please click on the above area to detect the screen saver" is displayed in guidance frame 173 .

[0294] It can be understood that Figure 17A shows the display of the positions of the first areas in two sensing units, but in fact it can also display only the positions of all sensing areas or part of the sensing areas in one sensing unit, or it can display the positions of all sensing areas or part of the sensing areas in all sensing units.

[0295] The user performs a touch operation on the first area position indicated in Figure 17A. In response to the user's touch operation on the first area, the electronic device executes the screen protector detection method provided in the embodiment of the present application, and then displays the prompt interface 174 as shown in Figure 17B. A prompt box 175 is displayed on the prompt interface 174. The text "Confirmed that the screen protector is currently installed and the functional mode of the touch screen has been adjusted" is displayed in the prompt box 175. In other embodiments, the text "Confirmed that the tempered glass film is currently installed and the functional mode of the touch screen has been adjusted accordingly" is displayed in the prompt box 175.

[0302] The preset touch data is touch data that meets preset conditions, and the preset conditions are related to the size or area of ​​the first sensing area and the second sensing area.
