[0026] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0027] The touch detection method, device, electronic device, and storage medium according to the embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0028] Currently, electronic devices using capacitive touch screens, such as mobile phones, may experience ghost points in scenarios such as charging, radio frequency interference, and calibration anomalies. Figure 1 As shown, Figure 1 This is a schematic diagram of a touch screen ghost point recognition scenario provided in an embodiment of the present disclosure, wherein a ghost point is an abnormal point that is not touched by the user but is recognized by the touch screen integrated circuit (Touch Integrated Circuit, Touch IC), which may cause the touch screen to be unable to respond to user input or automatic sliding and clicking, affecting the user experience.

[0029] In response to the above-mentioned problems, the present disclosure proposes a touch detection method. During the touch screen process, after the touch screen integrated circuit Touch IC detects a change in the capacitance value of a certain position on the touch screen and exceeds a change threshold, it obtains the coordinates, temperature and other data of the position and performs analysis and processing. If the position is not a touch position, the baseline value is recalibrated, thereby providing conditions for reducing the frequency of touch point ghost points, improving the reliability and accuracy of touch detection, and enhancing the user experience.

[0030] Figure 2 A schematic flow chart of a touch detection method provided by an embodiment of the present disclosure.

[0031] The embodiment of the present disclosure is described by taking the touch detection method configured in a touch detection device as an example. The touch detection device can be applied to any electronic device to enable the electronic device to perform a touch detection function.

[0032] like Figure 2 As shown, the touch detection method may include the following steps:

[0033] Step 201 : When it is detected that a capacitance change value corresponding to any position on the touch screen is greater than a first change threshold, a current first temperature value of any position is obtained.

[0034] The first change threshold is a critical value of capacitance change when any position on the touch screen is touched. It can be preset or determined by the touch detection device according to the performance of the touch screen. This disclosure does not limit this.

[0035] The following combination Figure 3 , the principle of the capacitance change value corresponding to each position of the touch screen is explained. Figure 3 As shown, Figure 3 This is a schematic diagram of the capacitance values ​​of the touch screen in different states provided by the embodiment of the present disclosure. Figure 3 The capacitance values ​​shown in the "Baseline Value" graph are the capacitance values ​​of each position on the touch screen in a non-touch state; the capacitance values ​​shown in the "Raw Data" graph are the capacitance values ​​corresponding to each position obtained by real-time detection of the touch screen; and the "Change Value" is the difference between the "Raw Data" and the "Baseline Value" of each position.

[0036] In the present disclosure, when the touch screen integrated circuit Touch IC detects that the capacitance change value at any position in the touch screen is greater than a first change threshold, it can determine the coordinates of the any position and obtain the current first temperature value of the any position through the temperature measuring device built into the touch screen (such as a temperature sensor), and then report the coordinate information and the first temperature value of the any position to the touch screen driver.

[0037] Step 202: Determine whether any position is a touch position according to the first temperature value.

[0038] In the present disclosure, after receiving the coordinates of any position and the first temperature value, the touch screen driver may analyze and process the first temperature value of any position to determine whether the position is a touch position.

[0039] In some possible implementations, any position is determined to be a touch position when a difference between a first temperature value and at least one second temperature value is greater than or equal to a difference threshold.

[0040] The second temperature value is the current temperature value of the reference position whose corresponding capacitance change value is less than the second change threshold.

[0041] The second change threshold is a critical capacitance value for determining that any position on the touch screen is not touched. It may be preset or determined by the touch detection device according to the performance of the touch screen, and this disclosure does not limit this.

[0042] The second change threshold may be the same as the first change threshold, or may be different from the first change threshold. For example, the second change threshold may be a value smaller than the first change threshold, which is not limited in the present disclosure.

[0043] The reference position is a position on the touch screen other than the position corresponding to the first temperature value.

[0044] Among them, the difference threshold is a temperature critical value used to determine whether a certain position has generated a temperature change due to being touched. It can be pre-set or determined by the touch detection device based on the current ambient temperature, etc. This disclosure does not limit this.

[0045] In the present disclosure, when the difference between the first temperature value and at least one second temperature value is greater than or equal to the difference threshold, it can be considered that the capacitance change at any position is caused by being touched. At this time, any position can be determined as a touch position.

[0046] In some possible implementations, when the difference between the first temperature value and at least one second temperature value is less than a difference threshold, it can be considered that the capacitance change at any position is not caused by being touched. In this case, any position can be determined as a non-touch position.

[0047] Step 203 : When any position is not a touch position, calibrate the baseline value of the touch screen to obtain a calibrated baseline value.

[0048] In the present disclosure, when any position is not a touch position, it can be considered that any position is not a position touched by the user, that is, the capacitance change value at this time is greater than the first change threshold, which is caused by other reasons. At this time, in order to minimize the frequency of abnormal touch detection, the baseline value of the touch screen can be calibrated to obtain the calibrated baseline value.

[0049] It should be noted that if any position is not a touch position, the touch screen driver will not report this position to the framework layer to avoid touch screen malfunction, ghost points, etc. In addition, the touch screen driver will notify the TouchIC to recalibrate the touch screen baseline value.

[0050] In the disclosed embodiment, when a capacitance change corresponding to any location on the touch screen is detected to be greater than a first change threshold, the current first temperature value of the location is obtained. Based on the first temperature value, whether the location is a touch location is determined. If the location is not a touch location, the baseline value of the touch screen is calibrated to obtain a calibrated baseline value. Thus, by monitoring capacitance changes and temperature changes at various locations on the touch screen to determine whether the location is a touch location, and triggering a calibration of the touch screen baseline value if a detection anomaly is determined at any location, touch detection anomalies are effectively avoided, the reliability and accuracy of touch detection results are improved, and the user experience is enhanced.

[0051] Figure 4 A flow chart of a touch detection method provided by an embodiment of the present disclosure is shown as follows: Figure 4 As shown, the touch detection method may include the following steps:

[0052] Step 401 : When it is detected that a capacitance change value corresponding to any position on the touch screen is greater than a first change threshold, a current first temperature value of any position is obtained.

[0053] The specific implementation of step 401 can refer to the detailed description of other embodiments of the present disclosure and will not be repeated here.

[0054] Step 402: Obtain the temperature value of the current environment of the touch screen.

[0055] In the present disclosure, after obtaining the current first temperature value of any position, the temperature value of the environment where the touch screen is currently located can be obtained.

[0056] It should be noted that, depending on the current environment in which the touch screen is located, the corresponding temperature values ​​may be the same or different, and this disclosure does not limit this.

[0057] Step 403: Determine a preset temperature range according to the ambient temperature.

[0058] The preset temperature range is a temperature range used to determine whether any position is a touch position. It can be pre-set or determined by the touch detection device according to the current ambient temperature. This disclosure does not limit this.

[0059] It should be noted that, depending on the temperature value of the environment in which the touch screen is currently located, the determined preset temperature range may be the same or different, and this disclosure does not limit this.

[0060] Step 404 : When the first temperature value falls within a preset temperature range, determine any position as a touch position.

[0061] In the present disclosure, when the first temperature value falls within a preset temperature range, it can be considered that the capacitance change at any position corresponding to the first temperature value is caused by being touched. In this case, the any position can be determined as a touch position.

[0062] It should be noted that when any of these positions is a touch position, the touch screen driver can report this position to the framework layer, and then the framework layer can send the reported position to the corresponding application (Application, APP) window through judgment, and the APP will use the touch position.

[0063] In the disclosed embodiment, when a capacitance change corresponding to any location on the touch screen is detected to be greater than a first change threshold, the current first temperature value of the location is first obtained. Then, the temperature value of the environment in which the touch screen is currently located is obtained. Based on the temperature value of the environment, a preset temperature range is determined. Finally, if the first temperature value falls within the preset temperature range, the location is determined to be a touch location. Thus, by determining whether a location is a touch location based on the relationship between the current temperature value of a location on the touch screen and the preset temperature range, the efficiency and reliability of touch detection results are improved.

[0064] Figure 5 A flow chart of a touch detection method provided by an embodiment of the present disclosure is shown as follows: Figure 5 As shown, the touch detection method may include the following steps:

[0065] Step 501 : When it is detected that a capacitance change value corresponding to any position on the touch screen is greater than a first change threshold, a current first temperature value of any position is obtained.

[0066] Step 502: Obtain the temperature value of the current environment of the touch screen.

[0067] Step 503: Determine a preset temperature range according to the ambient temperature.

[0068] The specific implementation of steps 501 to 503 can refer to the detailed description of other embodiments of the present disclosure and will not be repeated here.

[0069] Step 504 : If the first temperature value does not fall within a preset temperature range, determine that any position is a non-touch position.

[0070] In the present disclosure, when the first temperature value does not fall within the preset temperature range, it can be considered that the capacitance change at any position corresponding to the first temperature value is not caused by being touched. In this case, the any position can be determined as a non-touch position.

[0071] Step 505 : When any position is not a touch position, calibrate the baseline value of the touch screen to obtain a calibrated baseline value.

[0072] The specific implementation of step 505 can refer to the detailed description of other embodiments of the present disclosure and will not be repeated here.

[0073] In an embodiment of the present disclosure, when a capacitance change value corresponding to any position on the touch screen is detected to be greater than a first change threshold, a current first temperature value of the position is obtained, and then the temperature value of the environment in which the touch screen is currently located is obtained. A preset temperature range is then determined based on the temperature value of the environment. If the first temperature value does not fall within the preset temperature range, the position is determined to be a non-touch position. If the position is a non-touch position, the baseline value of the touch screen is calibrated to obtain a calibrated baseline value. Thus, by determining whether a position is a touch position based on the relationship between the current temperature value of any position on the touch screen and the preset temperature range, and triggering a calibration of the baseline value of the touch screen if a detection anomaly is determined at any position, the reliability and accuracy of the touch detection results are improved, thereby enhancing the user experience.

[0074] Figure 6 A flow chart of a touch detection method provided by an embodiment of the present disclosure is shown as follows: Figure 6 As shown, the touch detection method may include the following steps:

[0075] Step 601 : When it is detected that a capacitance change value corresponding to any position on the touch screen is greater than a first change threshold, a current first temperature value of any position is obtained.

[0076] Step 602: Determine whether any position is a touch position according to the first temperature value.

[0077] The specific implementation of steps 601 to 602 can refer to the detailed description of other embodiments of the present disclosure and will not be repeated here.

[0078] Step 603 : When any position is not a touch position, obtain the third temperature value currently corresponding to each position on the touch screen.

[0079] In the present disclosure, when any position is not a touch position, the temperature values ​​currently corresponding to each position in the touch screen can be obtained.

[0080] Step 604 : When the third temperature values ​​are within the preset temperature range, or when the differences between the third temperature values ​​are less than the difference threshold, the current capacitance value of each position is determined as the baseline value after touch screen calibration.

[0081] In the present disclosure, when each third temperature value is within a preset temperature range, or when the difference between each third temperature value is less than a difference threshold, it can be considered that each position in the touch screen is not touched. At this time, the current capacitance value of each position can be determined as the baseline value after calibration of the touch screen.

[0082] In an embodiment of the present disclosure, when a capacitance change value corresponding to any position on the touch screen is detected to be greater than a first change threshold, a current first temperature value of the position is obtained. Then, based on the first temperature value, whether the position is a touch position is determined. If the position is not a touch position, a current third temperature value corresponding to each position on the touch screen is obtained. If each third temperature value is within a preset temperature range, or if the difference between each third temperature value is less than a difference threshold, the current capacitance value of each position is determined as the baseline value of the touch screen after calibration. Thus, when any position is not a touch position, the baseline value of the touch screen is calibrated based on the current capacitance value and temperature value of each position on the touch screen, thereby reducing the frequency of touch detection anomalies and improving the accuracy of touch detection results.

[0083] In order to implement the above embodiments, the present disclosure further provides a touch detection device.

[0084] Figure 7 This is a schematic diagram of the structure of the touch detection device provided by an embodiment of the present disclosure.

[0085] like Figure 7 As shown, the touch detection device 700 may include: an acquisition module 701 , a determination module 702 , and a calibration module 703 .

[0086] An acquisition module 701 is configured to acquire a current first temperature value at any position on the touch screen when a capacitance change value corresponding to any position on the touch screen is detected to be greater than a first change threshold;

[0087] A determination module 702 is configured to determine whether any position is a touch position according to the first temperature value;

[0089] Optionally, the determining module 702 is specifically configured to:

[0090] When the first temperature value falls within a preset temperature range, determining any position as a touch position; or

[0091] When the first temperature value does not fall within the preset temperature range, any position is determined to be a non-touch position.

[0092] Optionally, before determining whether any position is a touch position according to the first temperature value, the determining module 702 is further configured to:

[0093] Get the temperature value of the touch screen's current environment;

[0094] Determine the preset temperature range based on the ambient temperature value.

[0095] Optionally, the determining module 702 is specifically configured to:

[0096] If the difference between the first temperature value and at least one second temperature value is greater than or equal to a difference threshold, determining any position as a touch position; or

[0097] determining any position as a non-touch position when a difference between the first temperature value and at least one second temperature value is less than a difference threshold;

[0098] The second temperature value is the current temperature value of the reference position whose corresponding capacitance change value is less than the second change threshold.

[0099] Optionally, the calibration module 703 is specifically configured to:

[0100] Obtain the third temperature value currently corresponding to each position of the touch screen;

[0101] When the third temperature values ​​are all within the preset temperature range, or when the differences between the third temperature values ​​are all less than the difference threshold, the current capacitance value of each position is determined as the baseline value after touch screen calibration.

[0102] The functions and specific implementation principles of the above modules in the embodiments of the present disclosure can be referred to the above method embodiments and will not be repeated here.

[0103] The touch detection device of the disclosed embodiment, when detecting that the capacitance change value corresponding to any position on the touch screen is greater than a first change threshold, obtains the current first temperature value of any position, then determines whether the position is a touch position based on the first temperature value. If any position is not a touch position, the touch screen baseline value is calibrated to obtain a calibrated baseline value. Thus, by determining whether a position is a touch position based on monitoring capacitance changes and temperature changes at each position on the touch screen, and triggering calibration of the touch screen baseline value if a detection anomaly is determined at any position, touch detection anomalies are effectively avoided, the reliability and accuracy of touch detection results are improved, and the user experience is enhanced.

Components of electronic device 12 may include, but are not limited to, one or more processors or processing units 16, system memory 28, and a bus 18 that connects various system components (including system memory 28 and processing unit 16).

[0108] Bus 18 represents one or more of several types of bus structures, including a memory bus or memory controller, a peripheral bus, an accelerated graphics port, a processor, or a local bus using any of a variety of bus architectures. Examples of these architectures include, but are not limited to, an Industry Standard Architecture (ISA) bus, a Micro Channel Architecture (MAC) bus, an Enhanced ISA bus, a Video Electronics Standards Association (VESA) local bus, and a Peripheral Component Interconnection (PCI) bus.

[0109] The electronic device 12 typically includes a variety of computer system readable media. These media can be any available media that can be accessed by the electronic device 12, including volatile and non-volatile media, removable and non-removable media.

[0110] The memory 28 may include computer system readable media in the form of volatile memory, such as random access memory (RAM) 30 and / or cache memory 32. The electronic device 12 may further include other removable / non-removable, volatile / non-volatile computer system storage media. By way of example only, the storage system 34 may be configured to read and write non-removable, non-volatile magnetic media ( Figure 8 Not shown, often called a "hard drive"). Although Figure 8 Although not shown, a disk drive for reading and writing to a removable non-volatile disk (e.g., a "floppy disk"), and an optical disk drive for reading and writing to a removable non-volatile optical disk (e.g., a Compact Disc Read Only Memory (hereinafter referred to as: CD-ROM), a Digital Video Disc Read Only Memory (hereinafter referred to as: DVD-ROM), or other optical media) may be provided. In these cases, each drive may be connected to the bus 18 via one or more data medium interfaces. The memory 28 may include at least one program product having a set (e.g., at least one) of program modules configured to perform the functions of the various embodiments of the present disclosure.

[0111] A program / utility 40 having a set (at least one) of program modules 42 may be stored, for example, in memory 28. Such program modules 42 include, but are not limited to, an operating system, one or more application programs, other program modules, and program data, each of which, or some combination thereof, may include an implementation of a network environment. Program modules 42 generally implement the functions and / or methods of the embodiments described herein.

[0112] The electronic device 12 can also communicate with one or more external devices 14 (e.g., a keyboard, pointing device, display 24, etc.), one or more devices that enable a user to interact with the electronic device 12, and / or any device that enables the electronic device 12 to communicate with one or more other computing devices (e.g., a network card, a modem, etc.). This communication can occur via an input / output (I / O) interface 22. Furthermore, the electronic device 12 can communicate with one or more networks (e.g., a local area network (LAN), a wide area network (WAN), and / or a public network such as the Internet) via a network adapter 20. As shown, the network adapter 20 communicates with other modules of the electronic device 12 via the bus 18. It should be understood that, although not shown, other hardware and / or software modules can be used in conjunction with the electronic device 12, including but not limited to microcode, device drivers, redundant processing units, external disk drive arrays, RAID systems, tape drives, and data backup storage systems.

[0114] The disclosed technical solution, when detecting a capacitance change at any location on the touch screen that is greater than a first change threshold, obtains the current first temperature value of the location. Based on the first temperature value, the system then determines whether the location is a touch location. If the location is not a touch location, the system calibrates the touch screen's baseline to obtain a calibrated baseline value. Thus, by monitoring capacitance changes and temperature changes at each location on the touch screen to determine whether the location is a touch location, and triggering a baseline calibration if a detection anomaly is detected at any location, the system effectively avoids touch detection anomalies, improves the reliability and accuracy of touch detection results, and enhances the user experience.
