[0026] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.
[0027] The term "multiple" as used herein refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.
[0028] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, stored data, displayed data, etc.) and signals involved in this application are all authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of relevant countries and regions. For example, the screen coverage information involved in this application is obtained with full authorization.
[0029] Please refer to Figure 1 , which shows a flow chart of a method for preventing accidental touches of a touch screen according to an exemplary embodiment of the present application. Figure 1 , the method comprising:
[0030] Step 101: Determine screen coverage information of the touch screen, where the screen coverage information is used to indicate whether the touch screen is covered with a protective film.
[0031] The screen coverage information is used to distinguish between the film-applied scene and the non-film-applied scene. For example, the screen coverage information may be a film-applied scene, which is used to indicate that the current touch screen is in a film-applied scene; for another example, the screen coverage information is a non-film-applied scene, which is used to indicate that the current touch screen is in a non-film-applied scene. In some embodiments, the terminal adds a film detection switch in the setting options; the user can set the screen coverage information by setting the film detection switch on or off. For example, when the touch screen is covered with a protective film, the user can set the film detection switch to the on state; and when the touch screen is not covered with a protective film, the user can set the film detection switch to the off state. In this step, the set screen coverage information is determined from the setting options of the touch screen. For example, the state of the film detection switch is determined from the setting options of the touch screen; when the film detection switch is on, the screen coverage information is determined to be a film-applied scene; when the film detection switch is off, the screen coverage information is determined to be a non-film-applied scene. In an embodiment of the present application, a film detection switch is set in the setting options, and the screen coverage information is determined by setting the state of the film detection switch, so that the screen coverage information is determined simply and efficiently.
[0032] In some embodiments, when the film detection switch is turned on, the user can also set the thickness of the protective film. For example, the terminal displays multiple protective film thicknesses, and the multiple protective film thicknesses are used by the user to select the thickness of the protective film currently attached to the touch screen. The user can select a protective film thickness from the multiple protective film thicknesses, and the selected protective film thickness is the thickness of the protective film currently attached to the touch screen. Accordingly, the screen coverage information includes not only the film that has been attached, but also the thickness of the film that has been attached.
[0033] Step 102: Obtain the accidental touch prevention condition that matches the screen coverage information.
[0034] The terminal stores the correspondence between the screen coverage information and the anti-false touch conditions; based on the screen coverage information, the terminal obtains the anti-false touch conditions that match the screen coverage information from the correspondence between the screen coverage information and the anti-false touch conditions. In some embodiments, the anti-false touch conditions include an effective touch area, and the effective touch area includes at least one of an effective touch width, an effective touch height, and an effective touch area; the effective touch width refers to the width of a continuous effective reporting point; the effective touch height refers to the height of a continuous effective reporting point, and the effective touch area refers to the area of a continuous effective reporting point, and the effective reporting point refers to the reporting point where the capacitance value and the default capacitance value are greater than the preset capacitance value. In the embodiment of the present application, the effective touch area is taken as an example for explanation.
[0035] After the touch screen is pasted with a protective film of a certain thickness, the suppression effect of edge anti-mistouch will become worse, thus causing false touches. The main reason is that the film will increase the probability of the user's finger touching the capacitive touch (ITO) material, causing the coupling capacitance induction to decrease. This will cause the user's mobile phone to click on the edge of the touch screen under the film, and the touch event will not meet the preset anti-mistouch conditions, increasing the probability of anti-mistouch. In the embodiment of the present application, the screen coverage information is used to determine whether the touch screen is filmed, and by distinguishing between the film-pasting scene and the non-film-pasting scene, the anti-mistouch conditions are dynamically switched to solve the problem of high false touch rate of edge anti-mistouch in the film-pasting scene.
[0036] Step 103: storing the accidental touch prevention condition.
[0037] The terminal stores the anti-false touch conditions so that the anti-false touch processing can be performed based on the stored anti-false touch conditions. The terminal collects touch signals at regular intervals and determines whether the touch screen is touched by an object (a user's finger or other object) based on the touch signals; when the touch screen is detected to be touched by an object, step 104 is executed; when the touch screen is not detected to be touched by an object, touch signals are continuously collected until the touch screen is detected to be touched by an object, and then step 104 is executed.
[0038] The basic principle of the touch screen is capacitive sensing. When the user's finger or other object touches the sensing material on the surface of the touch screen, the capacitance of the touch screen will change. The touch screen determines that the touch screen is touched by an object based on the capacitance change. In addition, the touch screen can also determine the number of fingers or objects pressed by an algorithm. Step 104 is executed only when the number of fingers or objects does not exceed a preset number. The preset number can be 2 or 3, etc.
[0039] The working principle of the touch screen is to trigger a scanning signal of a certain frequency at a certain time, detect whether the object is pressed on the touch screen, and calculate the coordinates based on the capacitive signal for reporting. Capacitive touch screens do not rely on the force of the finger to create and change the voltage value to detect the coordinates. Capacitive touch screens work through any object that holds an electric charge, including human skin. (The charge carried by the human body) Capacitive touch screens are made of materials such as alloys or ITO, and the charge is stored in micro-static networks that are thinner than hair. When a finger clicks on the screen, a small amount of current will be absorbed from the contact point, causing a voltage drop in the corner electrode, and the purpose of touch is achieved by inducing the weak current of the human body.
[0040] Step 104: When the touch screen detects a touch event, an anti-false touch process is performed on the touch event based on event information of the touch event and the stored anti-false touch conditions.
[0041] When the touch screen detects a touch event, the effective touch area of the touch event is determined, and the capacitance value of the reported point in the effective touch area is greater than the preset capacitance value; if the effective touch area is not greater than the area threshold included in the anti-false touch condition, the touch event is suppressed; if the effective touch area is greater than the area threshold included in the anti-false touch condition, the touch event is reported. In some embodiments, reporting the touch event refers to reporting the touch event to an upper layer, and the upper layer refers to the terminal system.
[0042] In some embodiments, the touch screen includes multiple reporting points, and the capacitance value of each reporting point is the difference between the capacitance value sent by the TX transmission channel and the capacitance value received by the RX receiving channel, that is, the touch screen is formed by the intersection of the TX transmission channel and the RX receiving channel. The terminal determines the event information of the touch event by collecting the capacitance value of the reporting point, and the event information includes the effective touch area. The process can be: the terminal determines the capacitance values of multiple reporting points of the touch screen, and for multiple reporting points arranged in sequence, if the capacitance value of the reporting point is greater than the preset capacitance value, the reporting point is a valid reporting point, and the area of the valid reporting point is accumulated, that is, the effective touch right; if the capacitance value of the reporting point is not greater than the preset capacitance value, the reporting point is a non-valid reporting point, and the area of the valid reporting point is not accumulated.
[0043] In an embodiment of the present application, the screen coverage information can indicate whether the touch screen is covered with a protective film. Therefore, the anti-mistouch conditions obtained based on the screen coverage information can distinguish between the film-sticking scene and the non-film-sticking scene, that is, different anti-mistouch conditions are set for the film-sticking scene and the non-film-sticking scene, so that the anti-mistouch conditions can be dynamically switched according to the film-sticking scene and the non-film-sticking scene, thereby solving the problem of high false touch rate of edge anti-mistouch in the film-sticking scene. Therefore, the present application can improve the accuracy of anti-mistouch.
[0044] Please refer to Figure 2 , which shows a flow chart of a method for preventing accidental touches of a touch screen according to an exemplary embodiment of the present application. Figure 2 , the method comprising:
[0045] Step 201: The terminal determines screen coverage information of the touch screen, where the screen coverage information is used to indicate whether the touch screen is covered with a protective film.
[0046] In some embodiments, this step is the same as step 101 and will not be repeated here.
[0047] Step 202: When the screen coverage information indicates that the touch screen is covered with a protective film, the terminal determines that the false touch prevention condition is a first false touch prevention condition.
[0048] The first anti-false touch condition includes a first effective touch area, and the first effective touch area includes at least one of a first effective touch width, a first effective touch height, and a first effective touch area. The first effective touch width refers to the width of a continuous effective reporting point; the first effective touch height refers to the height of a continuous effective reporting point, and the first effective touch area refers to the area of a continuous effective reporting point. A valid reporting point refers to a reporting point where the capacitance value and the default capacitance value are greater than a preset capacitance value. In the embodiment of the present application, the effective touch area is taken as an example for explanation. For example, in the film-sticking scenario, the first anti-false touch condition includes a first preset threshold condition, and the first preset threshold condition is that the first effective touch width is 3.
[0049] In some embodiments, the terminal can also distinguish that different film thicknesses correspond to different first anti-false touch conditions; accordingly, the step for the terminal to determine that the anti-false touch condition is the first anti-false touch condition can be: the terminal determines the thickness of the protective film; obtains the first anti-false touch condition that matches the thickness. The thickness of the protective film is negatively correlated with the first effective touch area included in the first anti-false touch condition, that is, the thicker the thickness of the protective film, the smaller the first effective touch area, and the thinner the thickness of the protective film, the larger the first effective touch area. In the embodiment of the present application, different first anti-false touch conditions are set according to different film thicknesses, so that the touch event can be more accurately judged to prevent false touches, further improving the accuracy of anti-false touch.
[0050] Step 203: When the touch coverage information is used to indicate that the touch screen is not covered with a protective film, the terminal determines that the false touch prevention condition is a second false touch prevention condition.
[0051] The first anti-false touch condition includes a first effective touch area, and the second anti-false touch condition includes a second effective touch area, and the first effective touch area is smaller than the second effective touch area. The second effective touch area includes at least one of a second effective touch width, a second effective touch height, and a second effective touch area. The second effective touch width refers to the width of a continuous effective reporting point; the second effective touch height refers to the height of a continuous effective reporting point, and the second effective touch area refers to the area of a continuous effective reporting point. A valid reporting point refers to a reporting point where the capacitance value and the default capacitance value are greater than a preset capacitance value. In an embodiment of the present application, the effective touch area is taken as an example for explanation. For example, in a scenario where no film is applied, the second anti-false touch condition includes a second preset threshold condition, and the second preset threshold condition is that the second effective touch width is 5.
[0052] Step 204: The terminal stores the first false touch prevention condition or the second false touch prevention condition.
[0053] In some embodiments, when the touch coverage information is used to indicate that the touch screen is covered with a protective film, the terminal stores a first anti-mistouch condition; when the touch coverage information is used to indicate that the touch screen is not covered with a protective film, the terminal stores a second anti-mistouch condition.
[0054] In some embodiments, the terminal stores the first anti-false touch condition by default, that is, before the anti-false touch condition is determined based on the screen coverage information, the terminal stores the first anti-false touch condition in advance; and after the anti-false touch condition is determined based on the screen coverage information, the terminal updates the stored first anti-false touch condition to the determined anti-false touch condition, thereby assuming that the touch screen is in a non-film-sticking scenario, thereby avoiding the inability to perform anti-false touch processing due to the failure to store the anti-false touch condition.
[0055] In some embodiments, after the terminal stores the first anti-false touch condition or the second anti-false touch condition, it can also display a first prompt message in the status bar of the terminal, and the first prompt message is used to prompt the current anti-false touch condition for preventing false touches, that is, the first prompt message prompts whether the first anti-false touch condition or the second anti-false touch condition has been stored; in addition, the first prompt message can also prompt the scene in which the touch screen is located, that is, the first prompt message prompts whether the touch screen is in a film-sticking scene or a non-film-sticking scene, so that the user can understand the anti-false touch conditions and avoid making wrong operations.
[0056] Step 205: When the touch screen detects a touch event, the terminal performs an anti-mistake touch process on the touch event based on the event information of the touch event and the stored anti-mistake touch conditions.
[0057] In some embodiments, when the stored false-touch prevention condition is the first false-touch prevention condition, the terminal performs false-touch prevention processing on the touch event based on the event information of the touch event and the first false-touch prevention condition; when the stored false-touch prevention condition is the second false-touch prevention condition, the terminal performs false-touch prevention processing on the touch event based on the event information of the touch event and the second false-touch prevention condition. In addition, the process of the terminal performing false-touch prevention processing on the touch event based on the event information of the touch event and the first false-touch prevention condition (or the second false-touch prevention condition) is similar to step 104 and is not repeated here.
[0058] For example, in the film-sticking scenario, the capacitance values of multiple reporting points included in the touch screen are as follows: Figure 3 As shown in the figure, the TX transmission channels are numbered 0-14, that is, there are 15 TX transmission channels; the RX reception channels are numbered 0-33, that is, there are 34 RX reception channels; the preset capacitance value can be 50. Figure 3 The capacitance values of the omitted and unmarked points are all 0, and Figure 3There are 10 valid reporting points, namely (TX13, RX26), (TX13, RX27), (TX13, RX28), (TX13, RX29), (TX13, RX50), (TX14, RX26), (TX14, RX27), (TX14, RX28), (TX14, RX29) and (TX14, RX50). Therefore, in the film-sticking scenario, the effective touch width is 5. In the non-film-sticking scenario, the capacitance values of the multiple reporting points included in the touch screen are as follows Figure 4 As shown, in Figure 4 The capacitance values of the omitted and unmarked points are all 0, and Figure 4 There are 6 valid reporting points, namely (TX13, RX27), (TX13, RX28), (TX13, RX29), (TX14, RX27), (TX14, RX28), (TX14, RX29). Therefore, in the non-film-sticking scenario, the effective touch width is 3. In the related art, the film-sticking scenario and the non-film-sticking scenario are not distinguished. Therefore, the anti-false touch conditions of the film-sticking scenario and the non-film-sticking scenario are the same, and the effective touch width is 5. The actual effective width reported by the film is 3, and the effective width included in the anti-false touch condition is 5. Then the current touch event is reported to the terminal system, causing a false touch. In the embodiment of the present application, in the film-sticking scenario, the effective width included in the first anti-false touch condition is 3, and in the film-sticking scenario, the effective width included in the second anti-false touch condition is 5. The actual effective width reported by the film is 3, and the effective width included in the second anti-false touch condition is 3, and the current touch event is suppressed.
[0059] In some embodiments, in step 204, the terminal stores the first anti-false touch condition and the second anti-false touch condition; in this step, the terminal can also determine whether to select the first anti-false touch condition or the second anti-false touch condition in combination with the application running in the foreground; for example, if the application running in the foreground is an application in the whitelist, the first anti-false touch condition is selected; and if the application running in the foreground is not an application in the whitelist, the second anti-false touch condition is selected. The whitelist stores applications with higher precision requirements. The present application not only combines the film-sticking scenario and the non-film-sticking scenario, but also combines the application running in the foreground to select the anti-false touch condition, thereby improving the accuracy of the determined anti-false touch condition, and then improving the accuracy of the anti-false touch.
[0060] In other embodiments, the first or second anti-false touch condition is still stored in step 204, and the terminal fine-tunes the stored anti-false touch condition in combination with the application running in the foreground; for example, if the application running in the foreground is an application in the white list, the effective touch area included in the stored anti-false touch condition is reduced (the effective touch width is adjusted from 3 to 2); and if the application running in the foreground is not an application in the white list, the effective touch area included in the stored anti-false touch condition is increased (the effective touch width is adjusted from 3 to 4), thereby accurately fine-tuning the anti-false touch condition and improving the accuracy of anti-false touch.
[0061] In some embodiments, in step 204, the terminal stores the first anti-false touch condition and the second anti-false touch condition; in this step, the terminal can also select the first anti-false touch condition or the second anti-false touch condition according to the state of the touch screen, and the state of the touch screen can be horizontal or vertical. For example, if the touch screen is in the horizontal state, the first anti-false touch condition is selected, and if the touch screen is in the vertical state, the second anti-false touch condition is selected, so that the anti-false touch condition is selected in combination with not only the film-sticking scene and the non-film-sticking scene, but also the state of the touch screen, thereby improving the accuracy of the determined anti-false touch condition, and further improving the accuracy of the anti-false touch.
[0062] In other embodiments, the first anti-false touch condition or the second anti-false touch condition is still stored in step 204, and the terminal fine-tunes the stored anti-false touch condition in combination with the state of the touch screen; for example, if the touch screen is in the horizontal state, the effective touch area included in the stored anti-false touch condition is reduced (the effective touch width is adjusted from 3 to 2); and if the touch screen is in the vertical state, the effective touch area included in the stored anti-false touch condition is increased (the effective touch width is adjusted from 3 to 4), thereby accurately fine-tuning the anti-false touch condition and improving the accuracy of anti-false touch.
[0063] In an embodiment of the present application, the screen coverage information can indicate whether the touch screen is covered with a protective film. Therefore, the anti-mistouch conditions obtained based on the screen coverage information can distinguish between the film-sticking scene and the non-film-sticking scene, that is, different anti-mistouch conditions are set for the film-sticking scene and the non-film-sticking scene, so that the anti-mistouch conditions can be dynamically switched according to the film-sticking scene and the non-film-sticking scene, thereby solving the problem of high false touch rate of edge anti-mistouch in the film-sticking scene. Therefore, the present application can improve the accuracy of anti-mistouch.
[0064] Please refer to Figure 5 , which shows a flow chart of a method for preventing accidental touches of a touch screen according to an exemplary embodiment of the present application. Figure 5 , the method comprising:
[0065] Step 501: The terminal determines screen coverage information of the touch screen, where the screen coverage information is used to indicate whether the touch screen is covered with a protective film.
[0066] In some embodiments, this step is the same as step 101 and will not be repeated here.
[0067] Step 502: The terminal obtains an anti-mistouch condition that matches the screen coverage information.
[0068] In some embodiments, this step is the same as step 102; alternatively, this step can be implemented through steps 202-203, which will not be described in detail here.
[0069] Step 503: The terminal stores the accidental touch prevention conditions.
[0070] In some embodiments, this step is the same as step 103 and will not be repeated here.
[0071] Step 504: When the duration of determining the screen coverage information reaches a preset duration, the terminal determines the screen coverage information of the touch screen again.
[0072] The terminal periodically updates the anti-false touch condition; therefore, when the time difference between the last time the screen coverage information was determined and the current time reaches a preset time length, the terminal determines the screen coverage information of the touch screen again; the process of the terminal determining the screen coverage information of the touch screen again is similar to step 501 and will not be repeated here. In the embodiment of the present application, the terminal periodically updates the anti-false touch condition, so that the touch event can be processed for false touch according to the latest anti-false touch condition, thereby improving the accuracy of the anti-false touch processing.
[0073] In some embodiments, since the user changes the touch coverage information through the film service switch, the terminal can also monitor the status of the film service switch; when the status of the film service switch changes, the screen coverage information of the touch screen is determined again, avoiding the waste of resources caused by frequently determining the screen coverage information when the screen coverage information has not changed.
[0074] In some embodiments, when a user applies a film to the touch screen, the terminal is often turned off; therefore, the terminal can display a second prompt message when it is turned on, and the second prompt message is used to prompt the user whether to apply a film to the touch screen, and when the user applies a film to the touch screen, guidance information for modifying the state of the film application service switch is provided, so that the user can modify the state of the film application service switch as soon as possible when applying a film to the touch screen, that is, modify the screen coverage information as soon as possible, and then the terminal can perform anti-mistouch judgment based on the latest screen coverage information, thereby improving the accuracy of anti-mistouch.
[0075] Step 505: When the re-determined screen coverage information is different from the last determined screen coverage information, the terminal obtains the false touch prevention condition matching the re-determined screen coverage information.
[0076] In some embodiments, if the screen coverage information determined again is that a film has been applied, the anti-false touch condition is the first anti-false touch condition; if the screen coverage information determined again is that a film has not been applied, the anti-false touch condition is the second anti-false touch condition.
[0077] Step 506: The terminal updates the stored accidental touch prevention condition to the re-determined accidental touch prevention condition.
[0078] In some embodiments, when the stored false-touch prevention condition is the first false-touch prevention condition, and the false-touch prevention condition determined again is the second false-touch prevention condition, the terminal updates the first false-touch prevention condition to the second false-touch prevention condition, that is, stores the second false-touch prevention condition. When the stored false-touch prevention condition is the second false-touch prevention condition, and the false-touch prevention condition determined again is the first false-touch prevention condition, the terminal updates the second false-touch prevention condition to the first false-touch prevention condition, that is, stores the first false-touch prevention condition.
[0079] Step 507: When the touch screen detects a touch event, the terminal performs an anti-mistake touch process on the touch event based on the event information of the touch event and the stored anti-mistake touch conditions.
[0080] In some embodiments, this step is the same as step 104 and will not be repeated here.
[0081] In the embodiment of the present application, the terminal periodically updates the false touch prevention conditions, so that the false touch prevention processing can be performed on the touch event according to the latest false touch prevention conditions, thereby improving the accuracy of the false touch prevention processing.
[0082] Please refer to Figure 6 , which shows a flowchart of a touch screen anti-mistaken touch method shown in an exemplary embodiment of the present application. The execution subject of the method is a terminal, which includes a film pasting service module and an anti-mistaken touch module. In the embodiment of the present application, the interaction between the film pasting service module and the anti-mistaken touch module is used as an example to explain the touch screen anti-mistaken touch method in detail. Figure 6 , the method comprising:
[0083] Step 601: The film-sticking service module determines screen coverage information of the touch screen, where the screen coverage information is used to indicate whether the touch screen is covered with a protective film.
[0084] In some embodiments, this step is similar to step 101 and will not be repeated here.
[0085] Step 602: The film pasting service module obtains the anti-mistouch condition matching the screen coverage information.
[0086] In some embodiments, this step is identical to step 102; alternatively, this step can be implemented through steps 202-203, which will not be described in detail here.
[0087] Step 603: the film pasting service module sends a storage instruction to the accidental touch prevention module. The storage instruction carries a command flag, and the command flag is used to mark the acquired accidental touch prevention condition.
[0088] When the anti-false touch condition obtained in step 602 is the first anti-false touch condition, the stored instruction is the first instruction; for example, the stored instruction is Flag=1, representing the first instruction; when the anti-false touch condition obtained in step 602 is the second anti-false touch condition, the stored instruction is the second instruction; for example, the stored instruction is Flag=2, representing the second instruction.
[0089] In some embodiments, the anti-mistaken touch module is set in the wireless access point (AP) system of the terminal, that is, the processing of the anti-mistaken touch module can be implemented by a program in the AP system. In other embodiments, the anti-mistaken touch module is set in the touch screen system of the terminal, and the anti-mistaken touch module is actually the touch screen driver in the touch screen system. Accordingly, this step can be: the film service module sends a storage instruction to the touch screen driver, and the storage instruction carries a command flag, and the command flag is used to mark the acquired anti-mistaken touch condition. The touch screen driver receives the storage instruction and forwards the storage instruction to the touch screen system. The operating system of the terminal is an Android operating system, and the Android operating system is divided into different software levels. For example, the Android operating system includes not only a touch screen driver, but also a battery management system service. The touch screen driver is responsible for receiving the storage instruction issued by the upper system service (film service module), and based on the storage instruction, it communicates data with the touch screen system, and is about to forward the storage instruction to the touch screen system. The battery management system service is responsible for monitoring the judgment of the insertion and removal status of the charger, and based on the insertion and removal status of the charger, controls the opening and closing of the charging switch.
[0090] Step 604: the anti-accidental touch module receives the storage instruction sent by the film-sticking service module, obtains the anti-accidental touch condition marked by the command flag, and stores the anti-accidental touch condition.
[0091] The anti-accidental touch module receives the first instruction sent by the film-sticking service module, obtains the first anti-accidental touch condition marked by the first instruction, and stores the first anti-accidental touch condition; the anti-accidental touch module receives the second instruction sent by the film-sticking service module, obtains the second anti-accidental touch condition marked by the second instruction, and stores the second anti-accidental touch condition. The anti-accidental touch module stores the first anti-accidental touch condition by default. Therefore, when the anti-accidental touch condition marked by the command flag is the first anti-accidental touch condition, the anti-accidental touch module does not update the anti-accidental touch condition; when the anti-accidental touch condition marked by the command flag is the second anti-accidental touch condition, the anti-accidental touch module updates the first anti-accidental touch condition to the second anti-accidental touch condition.
[0092] In some embodiments, when the film-sticking service module sends a storage instruction to the touch screen driver in step 603, step 604 can be replaced by: the touch screen system receives the storage instruction forwarded by the touch screen driver, obtains the anti-false touch condition marked by the command flag bit, and stores the anti-false touch condition in the register of the touch screen system through the data communication interface. The register is the memory of the touch screen system; the data communication interface can be an I2C interface, an SPI interface, or an I3C interface. The touch screen system also has its own central processing unit (CPU), and the touch screen system obtains the anti-false touch condition marked by the command flag bit through the CPU; in addition, the CPU of the touch screen system can also obtain the anti-false touch condition based on the screen coverage information; accordingly, the process can be: the film-sticking service module obtains the screen coverage information and sends the screen coverage information to the touch screen driver; the touch screen driver receives the screen coverage information, forwards the screen coverage information to the touch screen system, obtains the anti-false touch condition matching the screen coverage information, and stores the anti-false touch condition in the register of the touch screen system through the data communication interface. Similarly, the touch screen system stores the first anti-false touch condition by default. Therefore, when the anti-false touch condition marked by the command flag is the first anti-false touch condition, the touch screen system does not update the anti-false touch condition in the register; when the anti-false touch condition marked by the command flag is the second anti-false touch condition, the touch screen system updates the first anti-false touch condition in the register to the second anti-false touch condition.
[0093] Step 605: When the touch screen detects a touch event, the false touch prevention module performs false touch prevention processing on the touch event based on the event information of the touch event and the stored false touch prevention conditions.
[0094] In some embodiments, this step is similar to step 104 and will not be described again here.
[0095] In an embodiment of the present application, through the interaction between the film sticking service module and the anti-mistouch module, the anti-mistouch module can dynamically switch the anti-mistouch conditions through the film sticking scene and the non-film sticking scene, thereby solving the problem of high false touch rate of edge anti-mistouch in the film sticking scene. Therefore, the present application can improve the accuracy of anti-mistouch.

[0111] The storage module 703 is used to send a storage instruction to the anti-mistaken touch module 704 of the terminal through the film service module. The storage instruction carries a command flag bit, and the command flag bit is used to mark the obtained anti-mistaken touch condition; through the anti-mistaken touch module 704, the anti-mistaken touch condition marked by the command flag bit is obtained, and the anti-mistaken touch condition is stored.
[0112] In some embodiments, the false touch prevention module 704 is arranged in the AP system of the terminal, or the false touch prevention module 704 is arranged in the touch screen system of the terminal.
[0113] In some embodiments, the false touch prevention module 704 is used to determine the effective touch area of the touch event, and the capacitance value of the reporting point in the effective touch area is greater than the preset capacitance value; when the effective touch area is not greater than the area threshold included in the false touch prevention condition, the touch event is suppressed.
[0114] In an embodiment of the present application, the screen coverage information can indicate whether the touch screen is covered with a protective film. Therefore, the anti-mistouch conditions obtained based on the screen coverage information can distinguish between the film-sticking scene and the non-film-sticking scene, that is, different anti-mistouch conditions are set for the film-sticking scene and the non-film-sticking scene, so that the anti-mistouch conditions can be dynamically switched according to the film-sticking scene and the non-film-sticking scene, thereby solving the problem of high false touch rate of edge anti-mistouch in the film-sticking scene.
