[0002] Most current home appliances are designed to be program-displayed and controlled via touchscreen displays to meet consumers' needs for interactive home experiences. Through the appliance's screen, users can clearly understand device information and select a series of programs to control the appliance. The control of the appliance's touchscreen display is based on factory-preset touch parameters.

[0003] However, touch sensitivity is easily affected by environmental changes. For example, in high temperature and high humidity environments, water vapor in the air may condense on the surface of the touch film, changing its electrical properties and thus affecting the transmission and recognition of touch signals. In low temperature and dry environments, static electricity problems occur frequently, which can also interfere with touch sensitivity.

[0004] While existing technologies have proposed methods for calibrating touch sensitivity on touchscreens, these methods only address the sensitivity issues caused by interference devices associated with clothing-related devices, and do not solve the problem of how environmental factors affect the sensitivity of touch displays.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0057] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0058] The terms "first," "second," "third," "fourth," etc. (if present) in the specification and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0059] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0060] Most current home appliances are designed to be program-displayed and controlled via touchscreen displays to meet consumers' needs for interactive home experiences. Through the appliance's screen, users can clearly understand device information and select a series of programs to control the appliance. The control of the appliance's touchscreen display is based on factory-preset touch parameters.

[0061] However, touch sensitivity is easily affected by environmental changes. For example, in high temperature and high humidity environments, water vapor in the air may condense on the surface of the touch film, changing its electrical properties and thus affecting the transmission and recognition of touch signals. In low temperature and dry environments, static electricity problems occur frequently, which can also interfere with touch sensitivity.

[0062] While existing technologies have proposed methods for calibrating touch sensitivity on touchscreens, these methods only address the sensitivity issues caused by interference devices associated with clothing-related devices, and do not solve the problem of how environmental factors affect the sensitivity of touch displays. Based on these issues, to ensure touch accuracy and user usability, it is essential to adjust touch parameters in real-time according to external conditions to correct sensitivity.

[0063] To address the aforementioned technical problems, this application provides a screen touch calibration method. When a user touches the display screen, the method analyzes environmental data in real time across different time periods. Based on the changing parameters of the environmental data, if the changing parameters exceed a preset threshold, touch calibration is performed on the display screen. By acquiring environmental information at different times and calculating environmental change values, and performing touch calibration when environmental changes are significant, the method effectively compensates for the impact of environmental factors on the touch screen, thereby improving the accuracy and reliability of touch detection. This results in more precise responses to user touch operations and enhances the user experience.

[0064] The technical solutions of this application and how they solve the aforementioned technical problems are described in detail below with specific embodiments. These specific embodiments may exist independently or in combination with each other. Identical or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0065] Figure 1 A flowchart illustrating the screen touch calibration method provided in this application embodiment. Figure 1 .like Figure 1 As shown, the screen touch calibration method provided in this embodiment includes:

[0066] S101. In response to the user's touch operation on the display screen of the smart device, obtain the environmental information corresponding to the smart device. The environmental information includes: first environmental data and second environmental data.

[0067] The time interval between the acquisition time of the first environmental data and the acquisition time of the second environmental data is the first preset time.

[0068] Understandably, when a user performs a touch operation on the display screen of a smart device, the touch sensing system inside the smart device will immediately activate. This system can be based on capacitive, resistive, or other advanced touch detection technologies, capable of accurately identifying the location, pressure, and type of touch behavior; this application will not elaborate on these aspects. Once a user touch operation on the display screen is detected, the device's central processing unit can trigger the corresponding event processing flow.

[0069] Specifically, the equipment can be equipped with relevant sensors to obtain environmental data. For example, an ambient light sensor can be used to obtain the ambient light intensity, a temperature sensor can be used to collect the current ambient temperature, a humidity sensor can be used to obtain the ambient humidity, or a barometric pressure sensor can be used to measure the atmospheric pressure.

[0070] A first preset duration is maintained between the acquisition of the first environmental data and the acquisition of the second environmental data. The first preset duration can be set according to the needs of equipment detection, such as 2 seconds or 5 seconds, to ensure that environmental data with a certain time dimension for comparison is acquired, providing an effective data foundation for subsequent data analysis and processing.

[0071] S102. Determine the environmental change value corresponding to the smart device based on the first environmental data and the second environmental data.

[0072] Specifically, for each environmental parameter (such as temperature, humidity, light intensity, etc.), the difference between the first environmental data and the second environmental data can be calculated.

[0073] Understandably, the calculated environmental change values ​​provide a quantitative basis for further analysis of environmental conditions by the equipment. Based on these change values, combined with preset thresholds and algorithmic logic, the equipment can determine whether the environmental changes have reached a level requiring specific actions.

[0074] S103. Determine whether the environmental change value is greater than the first preset value; if yes, proceed to step S104; if no, proceed to step S105.

[0075] S104. Perform touch calibration on the display screen.

[0076] The device sets a basic calibration cycle for the screen during the initial setup. Based on this cycle, the touch sensitivity of the display screen can be maintained during device use. However, under the influence of external environmental factors, excessive environmental changes may affect the screen sensitivity. Therefore, when the environmental changes exceed a first preset value, the display screen is calibrated to ensure timely response when environmental changes significantly affect touch operation.

[0077] Understandably, if an environmental change exceeds its corresponding preset value, the smart device can trigger a touch calibration process. During calibration, the device first pauses any currently executing touch-related tasks to prevent interference. Then, the system invokes a screen calibration algorithm, which re-analyzes and adjusts the data collected by the touch sensing system based on pre-stored screen touch characteristic parameters. For example, it sends calibration signals to specific areas of the screen to detect the accuracy of touch feedback and corrects the touch coordinate mapping based on the detection results. After calibration, the device automatically resumes the previously paused tasks and returns to normal operation, ensuring users can continue using the smart device in a stable and accurate touch interaction environment.

[0078] In one possible implementation, in addition to common temperature and humidity data, multi-dimensional environmental data such as air pressure and light intensity can also be collected. By fusing these different types of data, the impact of environmental changes on the touchscreen can be assessed more comprehensively and accurately. For example, changes in air pressure may affect the touch sensitivity of the screen, and changes in light intensity may interfere with the reception of touch signals. By employing data fusion algorithms, such as the Kalman filter algorithm, the multi-dimensional environmental data can be processed to obtain more accurate values ​​of environmental changes.

[0079] By performing timely touch calibration, the negative impact of environmental changes on the touch sensitivity of the display screen can be eliminated, ensuring that users can obtain a stable and accurate touch operation experience in different environments.

[0080] S105. Perform touch calibration on the display screen according to the calibration cycle.

[0081] During device operation, a calibration cycle is set, and the device can perform touch calibration on the display screen according to the calibration cycle. Specifically, an internal timer is started, which counts the time at intervals according to the calibration cycle. When the timer reaches the set time of the calibration cycle, the device will first check the current operating status of the display screen.

[0082] Understandably, by performing touch calibration according to a set cycle, smart devices can periodically test and optimize the screen's touch performance, promptly identifying and correcting touch deviations caused by environmental changes, prolonged use, and other factors. This helps maintain the accuracy and stability of the screen's touch, improving the user experience.

[0083] The screen touch calibration method provided in this embodiment obtains environmental information corresponding to the smart device in response to a user's touch operation on the display screen of the smart device. This environmental information includes first environmental data and second environmental data, with the interval between the acquisition of the first and second environmental data being a first preset duration. Based on the first and second environmental data, an environmental change value corresponding to the smart device is determined. It is then determined whether the environmental change value is greater than a first preset value, and if so, touch calibration processing is performed on the display screen. By judging the environmental data of the smart device in real time and adjusting the touch calibration processing of the display screen accordingly, the sensitivity of the display screen is corrected based on the real-time environmental state, which helps improve the accuracy of screen touch control and enhances the user experience.

[0084] Figure 2 A flowchart illustrating the screen touch calibration method provided in this application embodiment. Figure 2 .like Figure 2 As shown, this embodiment is... Figure 1 Based on the embodiments, the screen touch calibration method is described in detail, and the method includes:

[0085] S201. In response to the user's touch operation on the display screen of the smart device, obtain the environmental information corresponding to the smart device. The environmental information includes: first environmental data and second environmental data.

[0086] Step S201 is similar to step S101 above, and will not be described in detail here.

[0087] S202. Determine the rate of change of temperature between the first temperature and the second temperature, and the rate of change of humidity between the first humidity and the second humidity.

[0088] S203. The rate of change of temperature and the rate of change of humidity are used as the environmental change values ​​between the first environmental information and the second environmental information.

[0089] For example, it can be done through The rate of temperature change is calculated, where R is the constant. T The formula is used to represent the rate of temperature change, where T1 represents the first temperature and T2 represents the second temperature. This formula reflects the proportion of temperature change relative to the initial temperature within a first preset time period. Correspondingly, the rate of humidity change can be expressed as follows: The calculation yields the following result: R H The two values ​​are used to represent the rate of change of humidity. H1 represents the first humidity level, and H2 represents the second humidity level.

[0090] Understandably, the system calculates and displays the rate of change of temperature and humidity, and determines whether to perform touch calibration based on whether the rate of change exceeds a preset threshold.

[0091] S204. Determine whether the rate of temperature change is greater than the first temperature change threshold and / or whether the rate of humidity change is greater than the first humidity change threshold; if yes, proceed to step S205; if no, proceed to steps S206-S209.

[0092] S205. Perform touch calibration on the display screen.

[0093] The server of the smart device can determine whether the rate of temperature change is greater than the first temperature change threshold and / or whether the rate of humidity change is greater than the first humidity change threshold. If either of the above conditions is met, it is considered that the environmental change may affect the touch operation, and then the display screen is subjected to touch calibration.

[0094] Understandably, devices can perform touch calibration on the display screen using built-in screen calibration algorithms. Specifically, based on precise measurement data of the screen's touch characteristics at the time of manufacture, the calibration algorithm can send high-precision calibration signals to multiple specific areas such as the four corners and the center of the screen. Taking the upper left corner of the screen as an example, after the calibration signal is sent, the device detects the signal strength and coordinate information fed back by the touch sensing system. If the fed-back coordinate information deviates from the theoretical upper left corner coordinates, the algorithm will adjust the mapping relationship of the touch coordinates according to a pre-set correction model. This adjustment is not a simple linear correction, but rather an optimization using a complex nonlinear algorithm that combines the physical characteristics of the screen and potential manufacturing errors. This application does not limit the specific touch calibration method used.

[0095] In one possible implementation, the device can monitor the calibration effect in real time, ensuring that the accuracy of the touch coordinates reaches the set precision standard by repeatedly sending calibration signals and comparing feedback data. Once calibration is complete and the accuracy meets the standard, the device can reactivate the previously paused application process and return to normal operation.

[0096] S206. Determine whether the change state is greater than the second preset value; if yes, proceed to steps S207-S208; if no, proceed to step S209.

[0097] S207. Determine the update calibration time corresponding to the environmental change value.

[0098] The first preset value is greater than the second preset value. If the environmental change value does not meet the first preset value, the device will again determine whether the temperature change rate is greater than the second temperature change threshold and whether the humidity change rate is greater than the second humidity change threshold. If the environmental change value (temperature change rate or humidity change rate) is greater than the second preset value, the device will determine the update calibration time corresponding to the environmental change value according to the preset rules.

[0099] Understandably, once the update calibration duration is determined, the device will periodically calibrate the screen according to that duration during subsequent use. For example, if the update calibration duration is 5 minutes, the device can automatically trigger the screen calibration process every 5 minutes, repeating the calibration algorithm's steps to ensure that the screen touch interaction remains accurate and stable under changing environmental conditions, providing users with a superior user experience.

[0100] In one possible implementation, it is determined whether the rate of temperature change is greater than a second temperature change threshold and / or whether the rate of humidity change is greater than a second humidity change threshold, wherein the second temperature change threshold is less than a first temperature change threshold and the second humidity change threshold is less than a first humidity change threshold.

[0101] Specifically, it can be determined whether the rate of temperature change is greater than the second temperature change threshold and / or whether the rate of humidity change is greater than the second humidity change threshold. If either of the above conditions is met, it is considered that the environmental change may affect the touch operation, and the calibration cycle is updated to ensure that the screen touch interaction remains accurate and stable under environmental changes.

[0102] In one possible implementation, the temperature change rate and / or humidity change rate are determined; the minimum of the temperature calibration duration and / or humidity calibration duration is determined as the update calibration duration corresponding to the changing state.

[0103] Specifically, for the temperature change rate, the device can determine its corresponding temperature calibration time according to pre-set rules. Similarly, it can determine its corresponding humidity calibration time based on the humidity change rate. For example, a mapping relationship between temperature change rate and temperature calibration time, and humidity change rate and humidity calibration time can be established through a large amount of experimental data and experience. This relationship can be recorded using a piecewise function, and the corresponding calibration time can be called when the corresponding preset value is reached.

[0104] Understandably, comparing the calculated temperature calibration time and humidity calibration time and selecting the minimum of the two as the calibration time for the changing state avoids unnecessary long calibration times and improves equipment operating efficiency and resource utilization. For example, if the temperature calibration time is 5 minutes and the humidity calibration time is 8 minutes, then the 5-minute temperature calibration time is selected as the update calibration time.

[0105] S207. Update the calibration cycle according to the updated calibration duration, and perform touch calibration on the display screen according to the updated calibration cycle.

[0106] The calibration period is used to indicate the reference time interval between two consecutive touch calibration processes on the display screen. The device has an initial calibration period pre-stored inside, which is a reference time interval set at the factory based on general environmental conditions and screen characteristics, and is used to indicate the time interval between two consecutive touch calibration processes on the display screen.

[0107] Understandably, after determining the update calibration duration, it can be directly replaced with the time interval between two consecutive calibration processes within the calibration cycle, and the calibration cycle can be updated according to this rule. After completing the calibration cycle update, the device can start a timer that counts according to the updated calibration cycle. When the timer reaches the end of a calibration cycle, the device will automatically trigger the display screen touch calibration process. Simultaneously, the device can continue timing and calibration operations according to the updated calibration cycle to adapt to the impact of environmental changes on screen touch accuracy, ensuring users receive a stable and accurate touch interaction experience when using smart devices.

[0108] Through this process, smart devices can dynamically adjust the calibration cycle according to environmental changes and rationally arrange touch calibration processing, ensuring screen touch quality while minimizing interference with the user's use of the device.

[0109] S209. Perform touch calibration on the display screen according to the calibration cycle.

[0110] Step S209 is similar to step S105 above, and will not be described again here.

[0111] The screen touch calibration method provided in this application acquires temperature and humidity data and calculates their rate of change, comparing the rate of change with first and second preset thresholds. If the rate of change is greater than the first preset threshold, touch calibration is performed immediately; if it is less than the first preset threshold but greater than the second preset threshold, a corresponding calibration duration is determined, and the minimum of the temperature and humidity calibration durations is taken as the final calibration duration. This update the calibration cycle, and touch calibration is performed according to the updated calibration cycle. The calibration strategy is precisely adjusted according to the degree of environmental change. For situations with large temperature and humidity changes, calibration is performed immediately; for smaller changes, the calibration cycle is updated appropriately to maintain screen touch accuracy, improving the user experience. Furthermore, through a hierarchical threshold judgment and duration determination mechanism, the method effectively balances the utilization of device resources while ensuring calibration effectiveness, avoiding excessively frequent calibrations that could affect device performance and user experience, thus achieving intelligent and efficient screen calibration management in different environments.

[0112] Figure 3 A flowchart illustrating the screen touch calibration method provided in this application embodiment. Figure 3 .like Figure 3 As shown, this embodiment is... Figure 1 and Figure 2 Based on the embodiments, a possible implementation method for the case where the display screen is not calibrated for touch is described in detail, the method including:

[0113] S301. Obtain the touch capacitance data of the display screen.

[0114] In some cases where touch calibration of the display screen is required, there may be scenarios where it is not performed. This could be because the user is currently interacting with the display screen, and performing touch calibration at this time could negatively impact the user experience. Therefore, in situations where touch calibration is required but not performed, it is necessary to determine the reason for the omission and when to perform touch calibration in the future.

[0115] Understandably, if the display screen has not undergone touch calibration, the device will acquire touch capacitance data from the screen. The touch sensing system of smart devices operates based on the principle of capacitive sensing, with multiple capacitive sensing units distributed across the screen surface. The device acquires touch capacitance data by sending specific electrical signals to these units and detecting changes in their feedback capacitance values.

[0116] Specifically, touch capacitance data can include capacitance information for different areas of the screen under different states, such as the baseline capacitance value when there is no touch, and the change in capacitance value when there is a touch operation. By analyzing the touch capacitance data, the device can further determine whether there are potential touch problems or user touch interventions on the screen, such as performance degradation of the capacitive sensing unit or whether it is affected by electromagnetic interference.

[0117] S302. Determine the operating status of the display screen based on the touch capacitance data.

[0118] S303. When the running state is user operation state, pause the touch calibration process until the running state is basic running state, then perform touch calibration process on the display screen.

[0119] The basic operating status is used to indicate that the current display screen has not detected any touch operation from the user.

[0120] Understandably, based on the acquired touch capacitive data, the device can further determine the operating status of the display screen. The device has pre-set judgment rules to distinguish different operating states. When the touch capacitive data shows frequent and irregular changes in capacitance values, and the magnitude of these changes exceeds a certain threshold, the device can determine that the display screen is in a user-operated state. This is because user touch operations, such as clicking or swiping, cause significant changes in the capacitance value of the capacitive sensing unit. When the touch capacitive data shows a relatively stable capacitance value, with fluctuations within a normal baseline range, the device will determine that the display screen is in a basic operating state, i.e., without user touch interference.

[0121] Specifically, when the device is in user operation mode, it will pause touch calibration to avoid interfering with user operations. The device continuously monitors touch capacitance data, and once the capacitance data meets the basic operating condition criteria (i.e., the capacitance value stabilizes), the device will immediately perform touch calibration on the display screen. During calibration, the currently touch-dependent application process will also be paused, and a screen calibration algorithm will be invoked to calibrate the screen. Once calibration is complete, the application process will resume.

[0122] In addition, performing touch calibration on the display screen under basic operating conditions, i.e. without user interference, enables the calibration algorithm to more accurately detect and adjust the screen's touch characteristics. This is because the touch capacitance data at this time more accurately reflects the screen's own state, thereby improving the accuracy of the calibration and ensuring the stability and accuracy of the screen's touch function.

[0123] The screen touch calibration method provided in this embodiment first acquires the touch capacitance data of the display screen when the smart device has not performed touch calibration processing on the display screen. Then, it determines the screen operating state based on the touch capacitance data. Touch calibration processing is paused when the operating state is the user operation state, and resumed when the operating state changes to the basic operating state. By rationally scheduling the timing of calibration processing, unnecessary calibration operations are avoided, reducing the waste of device resources. The device does not need to forcibly perform calibration during user operation, saving computing resources and power, and improving the overall operating efficiency of the device. At the same time, avoiding calibration processing while the user is operating the screen prevents interference with normal user use, ensuring smooth user operation and preventing user interruptions due to calibration, thus providing a better interactive experience.
