[0028] The technical solution in the embodiment of the present application is to solve the problem that the difference in BIOS performance is not considered in the above-mentioned capacitive touch screen detection and identification. The overall idea is as follows:

[0029] The BIOS identification evaluation value obtained through the BIOS identification data determines whether to perform BIOS identification optimization, and then the touch screen configuration complexity evaluation value obtained based on the touch screen configuration data determines whether to perform touch screen configuration optimization. Finally, the touch screen operation evaluation value obtained based on the touch screen operation data determines whether to perform touch screen optimization, thereby achieving the effect of improving the effectiveness of touch screen detection and identification of BIOS identification.

[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] like Figure 1As shown, it is a flowchart of a touch screen detection and identification method based on BIOS identification provided by an embodiment of the present application, and the method includes the following steps: S1, identifying the touch screen: reading the circuit connection state of the preset channel through the touch chip, identifying the touch screen according to the circuit connection state of the preset channel, and the circuit connection state of the preset channel represents the circuit connection state of the preset channel of the flexible printed circuit board interface of the capacitive touch screen; S2, BIOS identification capability evaluation: performing BIOS identification capability evaluation according to the acquired BIOS identification data to obtain a BIOS identification evaluation value, judging whether to perform BIOS identification optimization based on the BIOS identification evaluation value, and the BIOS identification evaluation value is used to quantitatively evaluate the identification capability of the BIOS; S3, touch screen configuration complexity evaluation: if BIOS identification optimization is performed, then performing touch screen configuration complexity evaluation according to the acquired touch screen configuration data to obtain a touch screen configuration complexity evaluation value, judging whether to perform touch screen configuration optimization based on the touch screen configuration complexity evaluation value, and the touch screen configuration complexity evaluation value is used to quantitatively evaluate the complexity of parameter configuration of the touch screen; S4, touch screen working performance evaluation: if touch screen configuration optimization is performed, then performing touch screen working performance evaluation according to the acquired touch screen working data to obtain a touch screen working evaluation value, judging whether to perform touch screen optimization based on the touch screen working evaluation value, and the touch screen working evaluation value is used to quantitatively evaluate the working performance of the touch screen.

[0032] It should be understood that the steps of identifying the touch screen are: prepare an intact touch screen for backup, and prepare a touch chip and a touch screen flexible printed circuit board (FPC) interface component; improve the touch screen FPC interface, and add connection channels at the outer end of the touch screen FPC interface; specially mark the preset channels of the touch screen FPC interface for easy distinction; different touches perform different short circuits between the added channels; the touch chip reads the preset channels and obtains the short circuit conditions in the channels, thereby automatically identifying the current touch screen; the special marking method is not limited, and can be specifically smeared with a marker or scratched with a knife; the preset channel represents the channel added to the touch screen FPC interface; the preset channel needs to ensure that it does not establish a connection relationship with the sensor of the touch screen; the circuit connection state indicates that different touches perform different short circuits between the added channels; identifying the touch screen according to the circuit connection state of the preset channel means using the circuit connection state of the preset channel on the touch screen to determine the touched area on the touch screen through the touch chip or controller, and identifying the touch position and operation.

[0033] It should be added that BIOS identification data includes identification time, identification information completeness coefficient, touch screen resolution, touch screen size, and channel capacitance value of preset channels; touch screen configuration data includes the number of parameter configuration items, the number of BIOS supported parameters, parameter configuration time, and parameter configuration error rate; touch screen working data includes touch response time, touch accuracy, touch screen refresh rate stability coefficient, noise suppression coefficient, touch screen power consumption, and touch sensitivity.

[0034] The identification time indicates the time taken by the BIOS from startup to identification of the touch screen, which is obtained by recording the time during the BIOS startup process until the BIOS completes the identification of the touch screen. The identification information completeness coefficient is obtained by calculating the ratio of the amount of hardware information read by the BIOS to the total amount of hardware information of the capacitive touch screen. The total amount of hardware information of the capacitive touch screen includes the physical characteristics, drive requirements, and touch parameter configuration of the touch screen, which are obtained through the driver of the capacitive touch screen. The amount of hardware information read by the BIOS is obtained through the Extended Display Identification Data (EDID) in the BIOS firmware. The touch screen resolution and touch screen size are obtained through the capacitive touch screen driver. The channel capacitance value of the preset channel is represented by measuring the capacitance value of the preset channel of the flexible printed circuit board interface of the capacitive touch screen with a capacitance tester.

[0035] The number of parameter configuration items is the number of configurable parameters obtained through the touch screen driver; the number of BIOS supported parameters is obtained by finding configuration items related to the touch screen in the BIOS settings and counting the number of parameters; the parameter configuration time represents the time from entering the configuration interface to completing the parameter configuration, which is obtained through the recorded timestamp; the parameter configuration error rate is obtained by deliberately setting wrong parameters during the configuration process, recording whether the system can correctly identify and prompt errors, and calculating the ratio of the number of wrong parameters identified to the number of wrongly set parameters; in the configuration process of the touch screen device, parameters usually refer to specific values, settings or function options that can be adjusted, modified or configured. Common touch screen parameters may include touch sensitivity, touch screen response speed, refresh rate, brightness, etc.; configuration items usually refer to options or entries that appear in a specific configuration interface or setting. Each configuration item corresponds to a setting item that can be adjusted by the user or the system. For example, in the BIOS settings, there may be options such as "set touch sensitivity" and "adjust touch screen resolution", and each option corresponds to a configuration item. Each configuration item has a specific parameter value, and the user can choose to modify the value.

[0036] The touch response time indicates the time difference from touch to screen response, which is obtained through the timestamp of the touch screen response; the touch accuracy indicates the deviation between the touch input position and the actual position, which is obtained by performing a ratio operation on the touch input position and the actual position; the refresh rate stability coefficient of the touch screen indicates the degree of deviation between the actual refresh rate of the touch screen and the preset refresh rate, which is obtained by performing a ratio operation on the actual refresh rate and the preset refresh rate; the noise suppression coefficient is expressed by measuring the ratio of the touch signal to the noise signal by the capacitive touch chip; the touch screen power consumption is expressed by the power consumption of the touch screen in the working state measured by the power consumption tester; the touch sensitivity indicates the minimum detectable change in touch capacitance, and the relationship between the capacitance change and the touch response is measured through the hardware testing equipment of the capacitive touch screen to determine the minimum detectable change; the actual position indicates a pre-set standard position on the capacitive touch screen, such as the upper left corner of the touch screen or the center of the screen, which is used as the standard position to compare the touch input; the preset refresh rate is set according to application requirements. In daily use scenarios, the preset refresh rate can be set to 60Hz.

[0037] In this embodiment, the total amount of hardware information of the capacitive touch screen is fixed and will not increase with the length of use. It has been determined and fixed in the physical structure and circuit configuration of the touch screen during the production process; the physical characteristics include but are not limited to the size, shape, and material of the touch screen; the driving requirements include but are not limited to the control circuit, driving method, and interface protocol of the touch screen; the touch parameter configuration includes but is not limited to the capacitance value, resistance value, inductance value, response time, sensitivity, and multi-touch capability of the touch screen.

[0038] This optimizes the BIOS settings and touch screen configuration, thereby improving the effectiveness of touch screen detection and recognition identified by the BIOS.

[0039] Further, the specific method of evaluating the BIOS recognition capability according to the acquired BIOS recognition data to obtain the BIOS recognition evaluation value is as follows: obtaining the recognition time index (i.e. ), the recognition time index is obtained by calculating the ratio of the recognition time to the preset recognition time in the database; the parameter configuration error index (i.e. ), the parameter configuration error index is obtained by calculating the ratio of the parameter configuration error rate to the preset parameter configuration error rate in the database; the identification information completeness coefficient (i.e. ), the identification information completeness coefficient and the preset identification information completeness coefficient in the database are processed to obtain the identification information completeness index (i.e. The identification information integrity coefficient is obtained by calculating the ratio of the amount of hardware information read by the BIOS to the total amount of hardware information of the capacitive touch screen; the touch screen resolution index (i.e. ), the touch screen resolution index is obtained by performing a ratio operation on the touch screen resolution and the preset touch screen resolution in the database; if the touch screen size is equal to the preset touch screen size in the database, and the parameter configuration error rate is less than the preset parameter configuration error rate in the database, the capacitance factor, recognition time index, parameter configuration error index, recognition information completeness index and touch screen resolution index are processed to obtain the BIOS recognition evaluation value; if the touch screen size is not equal to the preset touch screen size in the database, or the parameter configuration error rate is not less than the preset parameter configuration error rate in the database, the BIOS recognition evaluation value is recorded as 0; the capacitance factor represents the influence of the channel capacitance value of the preset channel on the BIOS recognition ability of the capacitive touch screen.

[0040] It should be understood that the specific method for obtaining the BIOS identification evaluation value is:

[0041]

[0042] In the formula, i represents the number of times the BIOS recognizes the capacitive touch screen. , N represents the total number of times the BIOS recognizes the capacitive touch screen, represents the BIOS recognition evaluation value of the i-th BIOS recognition of the capacitive touch screen, DRO represents the capacitance factor, Indicates the duration of the BIOS recognizing the capacitive touch screen for the i-th time. Indicates the amount of hardware information read by the BIOS for the i-th BIOS identification of the capacitive touch screen. Indicates the total amount of hardware information corresponding to the i-th BIOS recognition of the capacitive touch screen. Indicates the touch screen resolution of the capacitive touch screen identified by the BIOS for the i-th time. Indicates the touch screen size of the capacitive touch screen when the BIOS recognizes the i-th time. It represents the complete coefficient of the recognition information of the capacitive touch screen recognized by the BIOS for the i-th time, Indicates the preset identification information completeness coefficient, It indicates the parameter configuration error rate of the i-th BIOS recognition of the capacitive touch screen. Indicates the preset parameter configuration error rate (not 0), Indicates the preset recognition time. Indicates the preset touch screen resolution. Indicates the preset touch screen size.

[0043] In this embodiment, the preset recognition time is represented by the average value of the recognition time in the historical time period; the touch screen resolution represents the size of the minimum touch point that the capacitive touch screen can recognize; the preset resolution is set according to specific application requirements, for example, the touch screen resolution of a smart phone is 2 mm; the preset touch screen size is set according to specific application requirements, for example, the touch screen size of a smart phone is between 10-25 cm; the preset recognition information completeness coefficient is set according to specific application requirements, for example, in daily office use scenarios, the preset recognition information completeness coefficient can be set to 60; the preset parameter configuration error rate is represented by the average value of the parameter configuration error rate in the historical time period.

[0044] The capacitance factor is obtained from the database and indicates the degree of influence of the channel capacitance value of the preset channel on the BIOS identification evaluation value. For example, a mapping set of channel capacitance values ​​and their corresponding influencing factors is constructed based on the relationship between historical channel capacitance values ​​and BIOS identification data (such as identification time and identification information completeness coefficient), and the real-time channel capacitance value is input into the mapping set to obtain the corresponding capacitance factor.

[0045] The BIOS identification evaluation value in this algorithm involves processing multiple independent variables (identification time, identification information completeness coefficient, touch screen resolution, touch screen size, channel capacitance value of preset channels, parameter configuration error rate), and there is a mutual influence relationship between these independent variables; a capacitive touch screen with a higher resolution may require a longer identification time to ensure accurate data collection and processing, because subtle changes on the capacitive touch screen require more processing power and time; a shorter identification time may lead to an increase in the parameter configuration error rate; a larger identification information completeness coefficient may lead to a reduction in identification time, because complete information can complete the identification process more quickly; the resolution and size of the capacitive touch screen will also directly affect the selection of the channel capacitance value of the preset channel, because the larger the resolution and size of the capacitive touch screen, the higher the capacitance value may be required to ensure accurate touch identification; the larger the resolution and size of the touch screen, the longer the identification time may be, because more data or higher-precision data needs to be processed; if the capacitance value deviates from the normal range, it may affect the accuracy of channel identification.

[0046] In this algorithm, if the touch screen size is equal to the preset touch screen size in the database, and the parameter configuration error rate is less than the preset parameter configuration error rate in the database, the BIOS identification evaluation value is negatively correlated with the identification time. The closer the identification information completeness coefficient and the touch screen resolution are to the preset values, the greater the BIOS identification evaluation value. If the touch screen size is not equal to the preset touch screen size in the database, or the parameter configuration error rate is not less than the preset parameter configuration error rate in the database, the BIOS identification evaluation value is recorded as 0.

[0047] Taking the preset recognition time as 25s, the preset parameter configuration error rate as 0.5%, the preset recognition information completeness coefficient as 1, the preset touch screen resolution as 45mm, the capacitance factor as 1, the preset touch screen size as 10cm, the touch screen size of the i-th BIOS recognition capacitive touch screen as 10cm, and the parameter configuration error rate as less than 0.5% as an example, the change statistics of the BIOS recognition evaluation value are shown in Table 1:

[0048] Table 1 Statistics of changes in BIOS identification evaluation values

[0049]

[0050] From the first and second groups of data in the table, it can be seen that the BIOS identification evaluation value decreases with the increase of identification time; from the second and third groups of data, it can be seen that the BIOS identification evaluation value decreases with the increase of parameter configuration error rate; from the third and fourth groups of data, it can be seen that the BIOS identification evaluation value decreases with the increase of identification information completeness coefficient; from the fourth and fifth groups of data, it can be seen that the BIOS identification evaluation value increases with the increase of touch screen resolution.

[0051] Through the above steps, the recognition ability of BIOS is quantitatively evaluated, and the subsequent optimization of BIOS settings is achieved.

[0052] Furthermore, the specific process of judging whether to perform BIOS identification optimization based on the BIOS identification evaluation value is as follows: judging whether the BIOS identification evaluation value is less than a preset identification threshold: if the BIOS identification evaluation value is less than the preset identification threshold, performing BIOS identification optimization; if the BIOS identification evaluation value is not less than the preset identification threshold, not performing BIOS identification optimization; the specific steps of BIOS identification optimization are as follows: judging whether the BIOS identification evaluation value after the first identification optimization is less than the preset identification threshold, if the BIOS identification evaluation value is not less than the preset identification threshold, ending the BIOS identification optimization, otherwise performing the second identification optimization; the first identification optimization means detecting whether the BIOS firmware and the driver of the capacitive touch screen are the latest versions, if not, updating the BIOS firmware and the driver of the capacitive touch screen, and if so, re-identifying the capacitive touch screen; the second identification optimization means prompting the preset personnel to optimize the BIOS startup sequence, adjust the memory and CPU settings, the hard disk mode settings, optimize the circuit design, optimize the data transmission interface, and replace the capacitive touch screen; optimizing the data transmission interface is achieved by reducing the interface calls whose interface usage frequency is lower than the preset interface usage frequency.

[0053] In this embodiment, the preset recognition threshold is represented by the minimum value of the BIOS recognition evaluation value of the qualified recognition capability of the BIOS within the historical time period; the BIOS firmware version is detected by checking whether the BIOS firmware version is the latest version in the BIOS setting interface, and if it is not the latest version, the BIOS firmware version is automatically updated; the driver of the capacitive touch screen is detected by checking whether the driver of the capacitive touch screen is the latest version through the device manager, and if it is not the latest version, the driver of the capacitive touch screen is automatically updated; re-identifying the capacitive touch screen means re-identifying the capacitive touch screen through the BIOS.

[0054] Optimize the boot order of BIOS: Enter the BIOS setup interface, navigate to the Boot menu, use the arrow keys to select "Boot Priority" or "Boot Order", list the current boot device order, use the arrow keys to select the boot device to be changed, use the prompted keys (such as F5 / F6, + / -) to adjust the device priority, and move the hard disk to be started to the first place.

[0055] Hard disk mode setting: In BIOS, select the hard disk working mode according to the hard disk configuration and requirements, such as IDE mode, AHCI mode and RAID mode; IDE mode has better compatibility but lower performance; AHCI mode has higher performance and supports more advanced hard disk management functions; RAID mode is used for multiple hard disk combinations to provide data backup or performance improvement.

[0056] Differential signal transmission technology is used to optimize circuit design; the preset interface usage frequency is represented by the difference between the average and variance of the interface usage frequency in the historical time period; if the BIOS identification evaluation value after optimization by the above BIOS identification optimization measures is less than the preset identification threshold, if the BIOS identification evaluation value is not less than the preset identification threshold, the BIOS identification optimization is terminated, otherwise the capacitive touch screen is replaced.

[0057] Through the above steps, the recognition capability of BIOS is improved during the capacitive touch screen detection and recognition process.

[0058] Further, the specific method of evaluating the complexity of touch screen configuration according to the acquired touch screen configuration data to obtain the touch screen configuration complexity evaluation value is as follows: according to the relative relationship between the number of parameter configuration items and the number of BIOS supported parameters, the number of BIOS parameter configurable options (i.e. ), the number of BIOS parameter configurable options is obtained by calculating the ratio of the number of parameter configuration items to the number of parameters supported by the BIOS; the configuration error index (i.e. ), the configuration error index is obtained by calculating the ratio of the parameter configuration error rate to the parameter configuration time; the parameter configuration time index (i.e. ), the parameter configuration time index is obtained by calculating the ratio of the parameter configuration time to the preset parameter configuration time in the database; the configuration complexity coefficient (i.e. ), the configuration complexity coefficient is obtained by multiplying the number of parameter configuration items, the parameter configuration error rate and the parameter configuration time; the configuration complexity coefficient, the number of BIOS parameter configurable options, the configuration error index and the parameter configuration time index are processed to obtain the touch screen configuration complexity evaluation value.

[0059] The specific method for obtaining the touch screen configuration complexity evaluation value is as follows:

[0060] ;

[0061] In the formula, i represents the number of times the BIOS recognizes the capacitive touch screen. , N represents the total number of times the BIOS recognizes the capacitive touch screen, represents the touch screen configuration complexity evaluation value of the i-th BIOS identification of the capacitive touch screen, represents the optimized BIOS recognition evaluation value of the i-th BIOS recognition of the capacitive touch screen, Indicates the preset recognition threshold, Indicates the number of parameter configuration items for the BIOS to identify the capacitive touch screen for the i-th time. BCS indicates the number of parameters supported by the BIOS. It indicates the parameter configuration error rate of the i-th BIOS recognition of the capacitive touch screen. Indicates the parameter configuration time of the ith BIOS recognition of the capacitive touch screen. Indicates the preset parameter configuration time.

[0062] In this embodiment, the preset parameter configuration time is represented by an average value of the parameter configuration time in a historical time period; and the number of parameter configuration items is greater than the number of parameters supported by the BIOS.

[0063] The touch screen configuration complexity evaluation value in this algorithm involves processing multiple independent variables (the number of parameter configuration items, the number of parameters supported by BIOS, the parameter configuration time, and the parameter configuration error rate), and there is a mutual influence relationship between these independent variables; the more configurable options for BIOS parameters, the stronger the flexibility and adaptability of the system, and the more finely the system parameters can be adjusted, thereby reducing the configuration error rate; an increase in the number of configuration items may lead to a longer parameter configuration time because more time is required to select and adjust each parameter; an increase in the number of configuration items may also increase the configuration error rate because the possibility of erroneous operation or improper selection may increase during the selection process due to too many options; a larger number of parameters supported by BIOS may lead to a larger number of parameter configuration items, thereby increasing the complexity and configuration time of parameter configuration; a longer parameter configuration time may lead to an increase in the configuration error rate.

[0064] In this algorithm, when the BIOS identification evaluation value is not less than the preset identification threshold, the touch screen configuration complexity evaluation value increases with the increase of the configuration complexity coefficient, the number of BIOS parameter configurable options, and the parameter configuration time index.

[0065] It should be understood that the specific process of determining whether to perform touch screen configuration optimization based on the touch screen configuration complexity evaluation value is as follows: Determine whether the touch screen configuration complexity evaluation value is less than the preset complexity threshold: If the touch screen configuration complexity evaluation value is less than the preset complexity threshold, the touch screen configuration will not be optimized; If the touch screen configuration complexity evaluation value is not less than the preset complexity threshold, the touch screen configuration will be optimized; The preset complexity threshold is represented by the maximum value of the touch screen configuration complexity evaluation value in the historical time period.

[0066] The specific method of touch screen configuration optimization is as follows: evaluate the usage frequency of BIOS supported parameters, obtain parameters with a usage frequency lower than the preset parameter usage frequency, and set the parameters with a usage frequency lower than the preset usage frequency as default values; improve the BIOS startup speed through fast startup technology (such as unified extensible firmware interface); when it is detected that the parameter configuration error rate is greater than the preset parameter configuration error rate, prompt the preset personnel to correct the parameter settings; correct the parameter settings by entering the BIOS setting interface, finding the relevant parameters and adjusting them; the preset parameter usage frequency is represented by the difference between the average and variance of the parameter usage frequency in the historical time period; the preset parameter configuration error rate is set according to industry standards. For example, if the application scenario is daily office, the preset parameter configuration error rate can be set to 1%.

[0067] Taking the preset parameter configuration time as 300s, the preset identification threshold as 2, and the BIOS identification evaluation value as 5 as an example, the change statistics of the touch screen configuration complexity evaluation value are shown in Table 2:

[0068] Table 2 Statistics of changes in touch screen configuration complexity evaluation values

[0069]

[0070] From the first and second groups of data in the table, it can be seen that the touch screen configuration complexity evaluation value increases with the increase of the number of parameter configuration items; from the second and third groups of data, it can be seen that the touch screen configuration complexity evaluation value decreases with the increase of the number of BIOS supported parameters; from the third and fourth groups of data, it can be seen that the touch screen configuration complexity evaluation value increases with the increase of parameter configuration time; from the fourth and fifth groups of data, it can be seen that the touch screen configuration complexity evaluation value increases with the increase of parameter configuration error rate.

[0071] Through the above steps, the complexity of the parameter configuration of the touch screen is quantitatively evaluated, thereby achieving the optimization of the touch screen configuration and the improvement of BIOS performance.

[0072] Further, the specific method of evaluating the working performance of the touch screen according to the acquired working data of the touch screen to obtain the working evaluation value of the touch screen is as follows: according to the relative relationship between the touch response time and the preset touch response time in the database, the touch response time index (i.e. ), the touch response time index is obtained by calculating the ratio of the touch response time to the preset touch response time in the database; the touch screen power consumption index (i.e. ), the touch screen power consumption index is obtained by calculating the ratio of the touch screen power consumption to the preset touch screen power consumption in the database; the refresh rate stability coefficient (i.e. ), the refresh rate stability coefficient is obtained by calculating the ratio of the difference between the refresh rate of the touch screen and the preset refresh rate of the touch screen in the database to the preset refresh rate; the touch accuracy index (i.e. ), the touch accuracy index is obtained by calculating the ratio of the touch accuracy to the touch accuracy in the database; the noise suppression index is obtained according to the relative relationship between the noise suppression coefficient and the noise suppression coefficient in the database (i.e. ), the noise suppression index is obtained by performing a ratio operation on the noise suppression coefficient and the noise suppression coefficient in the database; the touch sensitivity factor, touch response time index, touch screen power consumption index, refresh rate stability coefficient, touch accuracy index and noise suppression index are processed to obtain the touch screen working evaluation value; the touch sensitivity factor indicates the influence of touch sensitivity on the working performance of the touch screen.

[0073] The specific method for obtaining the touch screen working evaluation value is as follows:

[0074] ; ; ; ; ; ; ; In the formula, i represents the number of times the BIOS recognizes the capacitive touch screen, , N represents the total number of times the BIOS recognizes the capacitive touch screen, represents the touch screen working evaluation value of the capacitive touch screen identified by the BIOS for the i-th time, α represents the touch screen working coefficient, Indicates the touch screen power consumption index. Represents the touch response time index, Represents the refresh rate stability coefficient, Represents the touch accuracy index, represents the noise suppression index, Indicates the preset complex threshold, represents the optimized touch screen configuration complexity evaluation value of the capacitive touch screen identified by the ith BIOS, Indicates the touch response time of the capacitive touch screen when the BIOS recognizes the i-th time. Indicates the touch screen power consumption when the BIOS identifies the capacitive touch screen for the i-th time, Indicates the refresh rate of the touch screen when the BIOS recognizes the capacitive touch screen for the i-th time, Indicates the touch accuracy of the capacitive touch screen identified by the BIOS for the i-th time. represents the noise suppression coefficient of the capacitive touch screen identified by the BIOS for the i-th time, LMD represents the touch sensitivity factor, Indicates the preset touch response time. Indicates the preset refresh rate of the touch screen. Indicates the preset touch accuracy. Represents the preset noise suppression coefficient, Indicates the preset minimum power consumption of the touch screen. Indicates the preset maximum power consumption of the touch screen.

[0075] In this embodiment, the preset maximum power consumption of the touch screen is set according to industry standards. For example, the standard power consumption of the capacitive touch screen is 1w, so the preset maximum power consumption of the touch screen is set to 1w; the preset minimum power consumption of the touch screen is represented by the minimum value of the touch screen power consumption in a historical time period; the preset touch response time is set according to application requirements. For example, in daily office use scenarios, the maximum touch response time can be set to 50ms, so the preset touch response time is set to 50ms; the preset refresh rate is set according to application requirements. For example, in daily office use scenarios, the preset refresh rate can be set to 60Hz; the preset touch accuracy is set according to industry standards. For example, in daily office use scenarios, the preset touch accuracy can be set to 1ms; the preset noise suppression coefficient is set according to industry standards. For example, in daily office use scenarios, the noise suppression coefficient can be set to 20dB.

[0076] The touch sensitivity factor is obtained from the database and represents the influence of touch sensitivity on the touch screen working evaluation value. For example, a mapping set of touch sensitivity and its corresponding influencing factors is constructed based on the relationship between historical touch sensitivity and touch screen working data (such as touch response time and touch accuracy), and the real-time touch sensitivity is input into the mapping set to obtain the corresponding touch sensitivity factor.

[0077] The touch screen working evaluation value in this algorithm involves processing multiple independent variables (touch response time, touch accuracy, touch screen refresh rate stability, noise suppression coefficient, touch screen power consumption, touch sensitivity), and there is a mutual influence relationship between these independent variables; the higher the touch sensitivity, the faster the touch response time can usually be achieved, because the touch input can be detected and processed more quickly; if the touch response time is longer, it may not be possible to accurately capture the user's fast or continuous touch operations, resulting in a decrease in touch accuracy; the shorter the response time is, the better the refresh rate stability; the lower the refresh rate stability, the lower the touch accuracy; if the noise suppression coefficient is insufficient, external interference may cause the touch screen to falsely report or miss touch operations, thereby reducing touch accuracy; the noise suppression coefficient usually requires a certain amount of power consumption to achieve, so while improving the noise suppression coefficient, the touch screen power consumption may increase; the touch screen power consumption lower than the preset touch screen power consumption may cause the touch screen to respond at a reduced speed, because the system requires more time to process and identify touch operations; in summary, the touch screen working evaluation value is negatively correlated with the touch response time, the touch screen power consumption, and the touch screen refresh rate stability; the touch screen working evaluation value is positively correlated with the touch accuracy and the noise suppression coefficient.

[0078] Through the above steps, the working performance of the touch screen is quantitatively evaluated, thereby achieving improvement in the working efficiency of the touch screen during the touch screen detection and recognition process.

[0079] Furthermore, the specific process of judging whether to perform touch screen optimization based on the touch screen working evaluation value is as follows: judging whether the touch screen working evaluation value is less than the preset working threshold: if the touch screen working evaluation value is less than the preset working threshold, the touch screen is optimized; if the touch screen working evaluation value is not less than the preset working threshold, the touch screen is not optimized; the touch screen optimization includes calibrating the touch screen input, optimizing the data structure, optimizing the data extraction, optimizing the data processing, optimizing the touch algorithm and optimizing the power consumption management strategy.

[0080] In this embodiment, the preset working threshold is represented by the minimum value of the touch screen working evaluation value in the historical time period.

[0081] Calibrating the touch screen input includes prompting the preset personnel to use the touch screen calibration tool to adjust the touch screen input coordinates and adjust the touch sensitivity parameters; optimizing the data structure by optimizing the data structure (such as a hash table) to store and query touch points; optimizing data extraction by extracting the characteristics of the touch signal through fast Fourier transform; optimizing data processing by parallel processing technology to accelerate the data processing process; optimizing the touch algorithm including smoothing the touch trajectory through the Kalman filter and adapting to the user's touch habits based on the K-nearest neighbor algorithm in the machine learning algorithm; optimizing the power consumption management strategy means dynamically adjusting the processor's operating frequency according to the usage of the capacitive touch screen.

[0082] Through the above steps, the accuracy and response timeliness of the capacitive touch screen in the touch screen detection and recognition process are improved, thereby improving the user's touch experience.
