[0047] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0048] In the above technical solution, the humidity value of the user's hand is collected when the user touches the screen of the electronic device. A first capacitance value corresponding to the humidity value is determined. The reference capacitance value of the screen is updated based on the first capacitance value, and touch recognition is performed based on the updated reference capacitance value. Through this technical solution, when faced with different humidity levels on the user's hand, the first capacitance value corresponding to that humidity is obtained to update the reference capacitance value of the screen, thereby calibrating the reference capacitance value based on humidity. Since the reference capacitance value affects the current used to locate the operation position during touch operation, after calibrating the reference capacitance value based on humidity, the current used for touch operation under that humidity level is consistent with or close to that when the hand is dry. Therefore, touch recognition using the updated reference capacitance value can solve the problem of misoperation or operation failure caused by wet hands. Furthermore, the above solution is applicable to scenarios with different humidity levels, improving its applicability.

[0055] Figure 5 This is a block diagram illustrating another screen control device according to an exemplary embodiment.

[0056] Figure 6This is a block diagram illustrating yet another screen control device according to an exemplary embodiment. Detailed Implementation

[0057] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0058] The electronic devices in the various embodiments of this disclosure can be electronic devices with a screen (touchscreen), such as mobile phones, tablets, wearable electronic devices (e.g., smartwatches), etc. When users are exercising, washing clothes, cooking, or in other similar scenarios, their hands may have a lot of sweat or moisture. In this case, operating the screen of an electronic device with wet fingers may result in touch operation failure or inaccuracy. For example, when there is liquid on the fingers, unlocking via the nine-grid key may result in touch disconnection, and unlocking will most likely fail.

[0059] The reason for this phenomenon is that capacitive screens are suitable for direct finger operation and support multi-touch, so most electronic devices with screens currently use capacitive screens. For a capacitive screen, when the human body is not touching the screen, the capacitance value sensed by the screen (the capacitance value borne by the capacitive electrodes) is its own capacitance value, which can be called the base capacitance value. When a user touches the capacitive screen, due to the human body's electric field, a coupling capacitance is formed between the user's finger and the screen surface. At this time, the capacitance value sensed by the screen becomes the sum of the capacitive electrodes and this coupling capacitance. Because of the change in capacitance, the operation of the human body can be sensed. Furthermore, since the screen is connected to high-frequency signals, and capacitors are direct conductors for high-frequency signals, the existence of this coupling capacitance causes the finger to absorb a small current. This current flows out from the electrodes at the four corners of the screen, and theoretically, the current flowing through the four electrodes is proportional to the distance from the finger to the four corners of the screen. The electronic device, through its controller, precisely calculates the ratio of the four currents to determine the location of the touch point. If a user operates the screen with wet hands, the capacitance value sensed by the screen differs from that sensed when the hands are dry. This difference in capacitance value leads to a discrepancy in the current absorbed by the finger during touch operation, which can easily cause operation failures or misoperations, such as inaccurate touch point positioning. Therefore, this disclosure provides a screen control method that can calibrate the screen's capacitance value by collecting the humidity value of the user's hands.

[0060] Figure 1This is a flowchart illustrating a screen control method according to an exemplary embodiment, the method being applied to an electronic device, such as... Figure 1 As shown, the method includes the following steps:

[0061] In step S101, the humidity value of the user's hand is collected when the user touches the screen of the electronic device.

[0062] For example, a humidity sensor can be installed on an electronic device to detect the humidity level of a user's hands. This humidity sensor can be one or more, positioned at a specific location on the electronic device. This location can be determined based on where the user's hands frequently hold the device. Taking a mobile phone as an example, the humidity sensor can be placed on the top, left, and / or right bezel, so that it comes into contact with the user's hand when holding the phone, facilitating subsequent detection of the user's hand humidity level. Alternatively, the humidity sensor can be placed in other easily accessible locations on the electronic device, such as on the back of the device, where the user's fingers can reach it while holding the device. This allows the user to actively contact the humidity sensor when their hands are damp, facilitating subsequent detection of the user's hand humidity level.

[0063] In step S102, the first capacitance value corresponding to the humidity value is determined.

[0064] It is understood that the screen in this embodiment is a capacitive touchscreen. Since the actual humidity value is uncertain, in order to calibrate the touchscreen under different humidity conditions, different humidity values ​​can be pre-set with corresponding capacitance values. That is, each humidity value can cover a certain humidity range, and a suitable touchscreen capacitance value is pre-set for each humidity value. These different humidity values ​​can be determined experimentally, and the correspondence between different humidity values ​​and capacitance values ​​is written into the electronic device before it leaves the factory. During the use of the electronic device, this correspondence can also be downloaded or updated from the cloud provided by the manufacturer. Furthermore, it should be noted that the values ​​in the correspondence between humidity values ​​and capacitance values ​​may differ for capacitive touchscreens of different manufacturers and specifications. The specific values ​​can be set according to the actual situation, and this disclosure does not impose any limitations.

[0065] Optionally, after collecting the humidity value of the user's hand through the humidity sensor, the humidity value can be sent to the control center of the electronic device. The control center can be the control software on the electronic device used to control the screen, or it can be the processor of the electronic device, or it can be the processing unit in the screen used to control the screen.

[0066] In one implementation, after the processor of the electronic device collects a humidity value through a humidity sensor, it can report the humidity value as a string to the control center of the electronic device. In this case, the control center can be the software of the electronic device used to control the screen, or a processing unit within the screen used to control the screen. The string contains the humidity value. After receiving the string, the control center extracts the current humidity value from it and determines the corresponding capacitance value based on the humidity value. The above-described string format is merely exemplary; any other possible information carrier or format can be used to report the humidity value to the control center of the electronic device.

[0067] In step S103, the reference capacitance value of the screen is updated according to the first capacitance value, and touch recognition is performed according to the updated reference capacitance value.

[0068] As mentioned earlier, the reference capacitance value, or base value, is the capacitance of the screen's capacitive electrodes when the human body is not in contact with the screen. It can be understood that updating the screen's reference capacitance value based on a first capacitance value can mean updating the first capacitance value to a new reference capacitance value. For example, the screen's reference capacitance value is typically stored in a register of the touch component, which can be a touch IC, a circuit, or a chip. If the first capacitance value is the calibrated reference capacitance value, it can be directly updated in this register as the updated reference capacitance value.

[0069] Alternatively, a new reference capacitance value can be determined based on the first capacitance value. For example, the first capacitance value can be a compensation value corresponding to the humidity value. After determining the first capacitance value, the current reference capacitance value in the register of the touch component can be read, and then the compensation value can be superimposed on the current reference capacitance value to obtain the updated reference capacitance value; or the average value between the first capacitance value and the reference capacitance value can be calculated, and the average value can be used as the updated reference capacitance value.

[0070] The above technical solution obtains a first capacitance value corresponding to the humidity of the user's hand to update the screen's reference capacitance value, thereby calibrating the screen's reference capacitance value based on humidity. As mentioned earlier, when a finger operates on the screen, it absorbs current, and the location of the touch point can be calculated based on the proportion of current flowing out from the electrodes at the four corners of the screen. The reference capacitance value affects the magnitude of this current. Therefore, after updating the reference capacitance value, the current absorbed by the hand during touch operation under the specified humidity is consistent with or close to the current absorbed by the hand under dry conditions. Thus, touch recognition using the updated reference capacitance value can solve the problem of misoperation or operation failure caused by wet hands. Furthermore, the above solution is applicable to scenarios with different humidity levels, improving its applicability.

[0071] Figure 2 This is a flowchart illustrating another screen control method according to an exemplary embodiment, the method being applied to an electronic device, such as... Figure 2 As shown, step S102 may include the following steps:

[0072] In step S1021, the humidity level corresponding to the humidity value is determined.

[0073] In step S1022, the first capacitance value corresponding to the humidity level is obtained.

[0074] For example, the correspondence between humidity range and humidity level, and the correspondence between humidity level and reference capacitance value can be preset in the electronic device. The correspondence between humidity range and humidity level includes different humidity levels corresponding to different humidity value ranges, and the correspondence between humidity level and reference capacitance value includes the correspondence between different humidity levels and different reference capacitance values.

[0075] This step S1021 may include:

[0076] Determine the target humidity range corresponding to the humidity value.

[0077] Based on the correspondence between humidity ranges and humidity levels, the humidity level corresponding to the target humidity range is determined. Therefore, the corresponding reference capacitance value can be determined based on the humidity level. For example, the pre-defined humidity levels may include low humidity, medium humidity, and high humidity.

[0078] In one implementation, the correspondence between the humidity range and humidity level can be stored in the control center of the electronic device, and the correspondence between the humidity level and the reference capacitance value can be stored in the memory of the touch component of the screen. Thus, under the control of the electronic device, after the humidity sensor collects a humidity value, it can send the humidity value to the control center. After obtaining the humidity value, the control center first determines the humidity range within which the humidity value falls, and then determines the corresponding humidity level based on the correspondence between the humidity range and the humidity level. The control center then sends the humidity level to the touch component of the screen, which can be the aforementioned touch IC. After receiving the humidity level sent by the control center, the touch component determines the first capacitance value corresponding to that humidity level based on the correspondence between different humidity levels and different reference capacitance values.

[0079] For example, step S1022 may include the following steps:

[0080] Electronic devices generate instructions carrying humidity levels via a control center.

[0081] The electronic device sends the instruction to the touch component through the control center, so that the touch component can obtain the first capacitance value corresponding to the humidity level from the memory of the touch component.

[0082] For example, the instruction can be a string with a specified format. The control center can send the humidity level to the touch component by sending this string containing the humidity level. For example, the string has a flag indicating the humidity level at a specified position. After receiving the string, the touch component can determine the humidity level based on the character of the flag in the string. For example, the position of the first character of the string can be designated as the flag. If the character of the flag is A, it indicates a low humidity level; if the character of the flag is B, it indicates a medium humidity level; and if the character of the flag is C, it indicates a high humidity level. Thus, after receiving the string sent by the control center, the touch component can determine the corresponding humidity value by recognizing the first character of the string. The above-described humidity level classification is merely an example. To achieve a finer granularity in the classification and a higher humidity recognition capability, the classification can be tailored to specific needs. The aforementioned identifier bits in the string can be set according to the specific format of the string. For example, if the string is in binary, two bits can be selected to indicate the humidity level. For instance, a value of 00 for these two bits indicates a low humidity level, 01 indicates a medium humidity level, and 01 indicates a high humidity level. The specific settings can be determined according to actual needs, and this disclosure does not impose any limitations.

[0083] It is worth mentioning that, in another implementation, the correspondence between humidity range and humidity level, as well as the correspondence between humidity level and reference capacitance value, can be stored in the memory of the touch component. After the humidity sensor collects a humidity value, it can directly send the humidity value to the touch component, allowing the touch component to determine the humidity level corresponding to the humidity value and the first capacitance value corresponding to the humidity level, and then execute step S103 to update the reference capacitance value. Alternatively, in another implementation, the correspondence between humidity range and humidity level, as well as the correspondence between humidity level and reference capacitance value, can be stored by the control center. After determining the humidity level based on the collected humidity value, the control center can further determine the first capacitance value corresponding to the humidity level based on the humidity level and the reference capacitance value, and send the first capacitance value to the touch component, so that the touch component executes step S103 to update the reference capacitance value based on the received first capacitance value.

[0084] Accordingly, in Figure 2 Following step 102, step S103 can be: updating the reference capacitance value of the touch component to the first capacitance value. That is, using the first capacitance value as the updated reference capacitance value.

[0085] For example, the current reference capacitance value of the screen is stored in the register of the touch component. Electronic devices typically recalibrate this reference capacitance value each time the screen is woken up. After obtaining the first capacitance value corresponding to the current humidity level, this first capacitance value is written into the register of the touch component to update the current reference capacitance value to the first capacitance value. The updated first capacitance value is the new reference capacitance value for the touch screen, allowing the new reference capacitance value of the screen to adapt to the current humidity level. This ensures that the humidity is taken into account when calibrating the screen's reference capacitance value. The updated reference capacitance value can correct the current absorbed from the screen when the finger is wet, making this current consistent with or only slightly different from the current absorbed from the screen when the finger is dry. This ensures that the touch point position calculated based on this current remains accurate, thus improving the problem of operation failure or malfunction when the user's hands are wet, thereby optimizing the user experience to a certain extent.

[0086] Optionally, Figure 3 This is a flowchart illustrating yet another screen control method according to an exemplary embodiment, the method being applied to an electronic device, such as... Figure 3 As shown, after step S103, the method may further include the following steps:

[0087] In step S104, upon receiving a first touch operation, the second capacitance value of the first touch operation is obtained.

[0088] In step S105, the difference between the second capacitance value and the updated reference capacitance value is obtained.

[0089] As described above, in step S103, the updated reference capacitance value can be determined based on the first capacitance value, or the first capacitance value can be directly used as the updated reference capacitance value. In this embodiment, the method of directly using the first capacitance value as the updated reference capacitance value is taken as an example. After step S103, the updated reference capacitance value is the first capacitance value. If the reference capacitance value has not been updated again after step S103 and before the first touch operation, the updated reference capacitance value in step S105 is the first capacitance value. Alternatively, if there are one or more update operations on the reference capacitance value after step S103 and before the first touch operation, the updated reference capacitance value in step S105 is the most recently updated reference capacitance value.

[0090] In step S106, when the difference is less than or equal to the first set threshold, the updated reference capacitance value remains unchanged, that is, touch recognition continues to be performed based on the updated reference capacitance value.

[0091] In step S107, if the difference is greater than the first set threshold, the updated reference capacitance value of the screen is updated according to the second capacitance value, and touch recognition is performed according to the updated reference capacitance value.

[0092] For example, taking the updated reference capacitance value in step S103 as the first capacitance value, and assuming that the reference capacitance value has not been updated again between step S103 and the first touch operation, the updated reference capacitance value in steps S105 to S107 is the first capacitance value. Thus, when the screen receives a user's touch operation, the second capacitance value at the start time of the current touch operation (the moment when the screen refreshes the first frame when the touch operation is received) can be collected, and the second capacitance value is compared with the current first capacitance value. If the difference between the second capacitance value and the first capacitance value is greater than the first set threshold, the current reference capacitance value needs to be updated from the first capacitance value to the second capacitance value, that is, the second capacitance value is used as the updated reference capacitance value. If the difference between the second capacitance value and the first capacitance value is less than the first set threshold, the reference capacitance value does not need to be updated again, that is, the reference capacitance value updated in step S103 is kept unchanged, i.e., the first capacitance value remains unchanged. If the reference capacitance value has been updated once or more after step S103, then the updated reference capacitance value in steps S105 to S107 is the most recently updated reference capacitance value.

[0093] Optionally, prior to step S101, the method may further include the following steps:

[0094] Upon receiving a second touch operation, obtain the third capacitance value of the second touch operation.

[0095] If the difference between the third capacitance value and the reference capacitance value is greater than the second set threshold, the step of collecting the humidity value of the user's hand when the user touches the screen of the electronic device is performed. The reference capacitance value is the capacitance value of the user's hand when the touch operation is performed under dry conditions.

[0096] Understandably, before activating the humidity sensor to collect the humidity value of the user's hands, it is possible to preliminarily determine whether the user's hands are wet. Since the humidity sensor is not yet activated at this time, identification can be based on the touch operation received on the screen. Therefore, before step 101, when the third touch operation is received, the capacitance value at the start of the third touch operation (the capacitance value resulting from the superposition of the current reference capacitance value and the coupling capacitance value generated by the current human body) can be obtained and compared with the reference capacitance value of the touch operation under dry conditions (the capacitance value resulting from the superposition of the current reference capacitance value and the coupling capacitance value generated by the human body under dry conditions). When the difference between the two capacitance values ​​is greater than the second set threshold, it can be determined that the user's hands are wet, so the humidity sensor can be activated to collect the humidity value of the user's hands to further determine the specific humidity value. When the difference in capacitance values ​​is less than or equal to the second set threshold, it can be considered that the user's hands are dry, and the humidity sensor can be deactivated, thereby saving power. The aforementioned reference capacitance value can be pre-set in the electronic device. This reference capacitance value can be determined through experimental data or empirical values. For example, in one implementation, multiple experimental personnel (since different individuals have different human electric fields, multiple personnel can be selected to participate) can be obtained by performing touch operations on the same electronic device with their hands dry. The capacitance values ​​of these multiple experimental personnel when performing touch operations are obtained (the capacitance value is the sum of the reference capacitance value of the screen and the coupling capacitance value generated by the human body at the start of the touch operation). Then, the average capacitance value is calculated based on the capacitance values ​​of these multiple experimental personnel when performing touch operations. This average capacitance value can be used as the aforementioned reference capacitance value and written into the electronic device before it leaves the factory.

[0097] Alternatively, in another possible implementation, given a fixed reference capacitance value, the coupling capacitance generated by the human body differs between touch operations performed when the hands are wet and when the hands are dry. This difference leads to a difference in the current absorbed by the hand from the screen during touch operations. Therefore, the humidity sensor can be activated to collect the humidity value of the user's hands if the difference between the current absorbed by the hand on the screen during the second touch operation and the current absorbed by the hand on the screen when the hands are dry exceeds a preset current threshold.

[0098] Optionally, the humidity sensor may be a sensor containing a humidity-sensitive element, which can be resistive or capacitive. Common humidity sensors include lithium chloride humidity sensors, alumina hygrometers, and ceramic humidity sensors. The type of humidity sensor can be selected according to actual needs, and this disclosure does not limit it.

[0099] Optionally, the humidity sensor described above in the electronic device can also be used to detect air humidity or humidity in other scenarios. For example, when the humidity sensor detects an air humidity value, it can be displayed through the electronic device's application to remind the user of the current air humidity. Alternatively, for electronic devices without waterproof functionality, if the humidity value detected by the humidity sensor exceeds a certain threshold, it can be determined that the electronic device has been dropped into water, and the power can be cut off to prevent short circuits caused by water ingress, thus protecting the electronic device.

[0100] In the above technical solution, the humidity value of the user's hand is collected when the user touches the screen of the electronic device. A first capacitance value corresponding to the humidity value is determined. The reference capacitance value of the screen is updated based on the first capacitance value, and touch recognition is performed based on the updated reference capacitance value. Through this technical solution, when faced with different humidity levels on the user's hand, the first capacitance value corresponding to that humidity is obtained to update the reference capacitance value of the screen, thereby calibrating the reference capacitance value based on humidity. Since the reference capacitance value affects the current used to locate the operation position during touch operation, after calibrating the reference capacitance value based on humidity, the current used for touch operation under that humidity level is consistent with or close to that when the hand is dry. Therefore, touch recognition using the updated reference capacitance value can solve the problem of misoperation or operation failure caused by wet hands. Furthermore, the above solution is applicable to scenarios with different humidity levels, improving its applicability.

[0118] The first capacitance value corresponding to the humidity level is obtained from the memory of the touch component, which stores multiple capacitance values ​​corresponding to humidity levels.

[0119] Optionally, the control module 403 is configured as follows:

[0120] The first capacitance value is written into the register of the touch component to update the current reference capacitance value in the register to the first capacitance value; touch recognition is performed based on the updated reference capacitance value.

[0121] Optionally, the touch component is a touch IC.

[0122] By employing the above technical solution, when faced with different humidity levels on the user's hands, a first capacitance value corresponding to that humidity is obtained to update the screen's reference capacitance value. This allows for humidity-based calibration of the screen's reference capacitance value. Since the reference capacitance value affects the current used to locate the operation position during touch operation, humidity-based calibration ensures that the current during touch operation at that humidity level is consistent with or close to that when the hands are dry. Therefore, touch recognition using the updated reference capacitance value can solve the problem of misoperation or operation failure caused by wet hands. Furthermore, the above solution is applicable to scenarios with different humidity levels, improving its applicability.
