With the rapid development of the smart electronic equipment market, the shipments of capacitive touch panels are showing a rapid growth trend. Touch screens, especially capacitive screens, are the most important way of human-computer interaction, and their performance directly affects the operation of touch screens. Experience has a great impact on the experience of using the whole machine. .

At present, most touch screens are capacitive touch panels (Capacitive Touch Panel, CTP). When the user touches the capacitive touch screen, the self-mutual capacitance value of the touch screen changes, and the capacitance sensing value (Rawdata) obtained by the touch IC through row and column scanning sampling will change, and the coordinates of the touch point are calculated by detecting the change in Rawdata, and Report the coordinate data to the electronic device. Specifically, by calculating the difference between the Rawdata and the baseline value (Baseline), the capacitance difference data (diffdata) representing the variation of the Rawdata is obtained. The diffdata is used as input to obtain the touch through a complex touch algorithm. The coordinates of the point.

In the related technology, the temperature change of the touch screen environment will cause the Rawdata obtained by IC scanning to be abnormal (for example, lifted), resulting in problems such as false alarm points, no function, and insensitive clicks on the touch screen. In view of the above problems, the currently commonly used optimization method is: when the finger touches the touch screen, update the baseline data (Baseline) to offset the abnormal lifting value of diffdata in the non-touch area, and then when the finger leaves the touch screen After that, update the Baseline again to restore the Baseline again. Since the above method updates the Baseline when the touch screen receives touch input, and the touch IC will not calculate the coordinates when updating the base, so when the touch input is received In the case of updating the Baseline, the accuracy of the current touch input reporting points will be low, such as missing points or disconnection, resulting in poor user experience.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

It should be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application can be practiced in sequences other than those illustrated or described herein, and that references to "first," "second," etc. distinguish Objects are generally of one type, and the number of objects is not limited. For example, there may be one or more first objects. In addition, "and/or" in the specification and claims means at least one of the connected objects, and the character "/" generally means that the related objects are an "or" relationship.

The method for processing screen data provided by the embodiment of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

First, the process of sampling touch events on the screen will be described in detail. Capacitive touch detects fingers by detecting changes in self-mutual capacitance caused by finger touches. When the finger touches, the capacitance value of the self-mutual capacitance changes, and the capacitive sensing data (that is, Rawdata) obtained by the touch IC through row and column scanning sampling will change, and the coordinates of the touch point are calculated by detecting the variation of Rawdata, and then the coordinate data is passed through SPI/I2C reports to the terminal IC, which is the whole process of touch event sampling.

After the touch IC acquires Rawdata through scanning and sampling, it will establish a baseline data (Baseline). The touch IC will establish a Baseline with a frame of Rawdata with no touch event and a high level of full-screen data. The capacitance difference of each frame of data The value data (diffdata) is obtained by subtracting the Baseline from the Rawdata collected in each frame scan, and the diffdata goes through a series of filtering, center of gravity, and smoothing algorithms to obtain the actual coordinates of the touch point. As shown in (a) in Figure 1, it is the diffdata data obtained when a single finger is touched. When a touch event occurs, the envelope of the touch area (dotted line box) can be clearly captured on the diffdata plane (that is, a frame of difference data is obtained). Area). It should be noted that the benchmark data of the touch IC is not static after the benchmark data is established, because the frequency of touch scanning and the ambient temperature change, and these changes will cause changes in Rawdata. In order to ensure that touch points will not be falsely reported, Baseline It needs to be slowly and dynamically updated with the changing trend of Rawdata.

Secondly, based on the entire process of touch event sampling mentioned above, currently, in the face of some complex scenarios, the processing effect of existing touch screen algorithms is poor. For example, high and low temperature environment switching, the capacitance value changes with the temperature change, the capacitive touch IC detects the finger by detecting the self-mutual capacitance value change caused by the finger touch, so the temperature change will cause the signal amount detected by the IC That is, the Rawdata changes, especially in the self-capacitance scanning mode. The self-capacitance scanning detects the finger by detecting the change of the coupling capacitance of the sensor to the ground, which is more affected by the temperature. In the low temperature mode, the Rawdata obtained by IC scanning sampling will be relatively small, and in the high temperature mode, the Rawdata obtained by IC scanning will be relatively large, and the lower the temperature, the smaller the Rawdata, and the higher the temperature, the larger the Rawdata.

Because temperature changes will bring about changes in Rawdata, and changes in Rawdata will cause Baseline to be in a dynamic update state, which brings about two problems. One is that the changes in Rawdata caused by temperature changes are faster than the update speed of the baseline data (Baseline). The second reason is that when a touch occurs, the touch IC will not update the Baseline. If the ambient temperature changes greatly at this time, the Rawdata plane (that is, one frame of capacitive sensing data) will be different from the Baseline plane (that is, one frame of reference data) Will produce a large offset:

The data changes in the two temperature switching scenarios are listed below:

1) When the electronic device is switched from a low-temperature environment to a high-temperature environment, Rawdata will increase as a whole. If the update of the Baseline plane is slow or stops, the value of the Rawdata plane will increase relative to the value of the Baseline plane as a whole, showing that the diffdata in most areas is A positive value, as shown in (b) in Figure 1, is the diffdata data obtained when switching from low temperature to high temperature without touch. If the diffdata of the non-touch area exceeds the reporting point threshold, it will display false alarm points and reduce user experience;

2) When the electronic device switches from a high temperature environment to a low temperature environment, the Rawdata will decrease as a whole, and the value of the Rawdata plane will decrease as a whole relative to the value of the Baseline plane, showing that the diffdata in most areas is a negative value, as shown in Figure 1 As shown in (c), it is the diffdata data obtained when there is no touch at high temperature and low temperature. The negative value in the touch area will offset the sensing amount generated by the finger. When the sensing amount of the finger is lower than the reporting threshold, the touch screen will show no function , The click is not sensitive, reducing the user experience.

In related technologies, in view of the above-mentioned problems such as high and low temperature switching that cause false alarm points on the touch screen, no function, and insensitive clicks, some commonly used optimization methods are:

1) The baseline data is strengthened when the finger is touched, and the abnormal lifting value of the diffdata in the non-touch area is removed, and then the baseline data is updated again after the hand is raised, and the Baseline including the finger touch sensing amount will be restored to the Baseline under the five-touch state, but Since the diffdata is obtained by subtracting the Baseline from the Rawdata, the touch IC will not calculate the coordinates and report points when updating the baseline data, so updating the baseline data when there is a touch will lead to missing points and disconnection problems , affecting user experience;

2) Detect the lift rate (or drop rate) of full-screen diffdata after temperature switching, increase the update speed of Baseline according to the change of Rawdata, and let the update speed of Baseline quickly adapt to temperature changes when the user raises his hand or is idle without touching Rawdata changes brought about. However, this method also has the following two problems. On the one hand, when the full-screen diffdata is lifted, the update speed of the Baseline is accelerated, and the real-time performance is poor. If the user has been using the touch-screen terminal after warming up, the Baseline will stop updating, which is easy. False alarm points affect the user’s use. On the other hand, after warming up, the full-screen diffdata lifting data features are similar to full-screen large-area palm pressing. These two states are easy to confuse. When the current state is mistakenly confirmed as large-area pressing The screen will trigger a large area of suppression, which means that the touch screen has no function and the user experience is poor;

3) After the electronic device host monitors the temperature information, it will notify the touch IC in real time through SPI/I2C, and the IC detects the high and low temperature environment change information to perform related algorithm preprocessing. This processing also has two disadvantages. On the one hand, the main control detection of electronic equipment The temperature is the internal temperature, which has a certain difference from the temperature of the touch screen node capacitance. The software implementation effect may not be good. On the other hand, increasing the interaction information between the main control and the touch IC will increase the hardware power consumption and software development costs, and it is not easy to deliver the effect of the whole machine. .

The present application proposes a method for optimizing the touch effect of switching between high and low temperatures according to the differences in temperature sensitivity of node capacitances in different areas of the touch screen. Based on the external structure of electronic equipment, it is realized to analyze the sensitivity difference of the touch screen capacitance node to the temperature difference change, and to detect the ambient temperature according to the difference of the Rawdata data collected by the nodes in different regions brought about by the temperature difference change. When the temperature of the touch screen environment occurs When changing, by detecting changes in the baseline data Baseline plane, the relevant algorithms are quickly switched for data processing, avoiding false positives, non-functional and insensitive problems, and improving user experience.

The method for detecting the ambient temperature of the touch screen of the present application is described below in combination with specific application scenarios:

Taking a mobile phone whose electronic device is a single speaker hole at the bottom of the full screen as an example, its appearance is shown in (a) in FIG. 2 . Since the bottom of the electronic device is equipped with USB ports, speakers, earphone holes, and microphone holes, compared with the top area (camera area), the bottom area of the touch screen has a larger contact area with the air and is more affected by temperature changes, especially the right The lower corner area is most sensitive to temperature changes.

Because the touch screen module of electronic equipment will check the capacitance value of the node when it leaves the factory, therefore, under normal temperature environment, the difference between the capacitance value of the far and near end nodes is not large, and the Rawdata matrix collected by the touch IC scan has a high flatness. (b) in Figure 2 is a schematic diagram of the detected node Baseline data in a normal temperature (25°C) environment and no touch input on the screen of the electronic device. It can be seen from (b) in Figure 2 that the rectangular The overall data difference between the Baseline data in the frame 21a and the Baseline data in the rectangular frame 22a is small, that is, the overall difference in the capacitance value between the upper right corner area of the screen and the lower right corner area of the screen is small.

When switching from a high temperature environment to a low temperature environment, compared with the top area, the bottom area of the touch screen will cool down faster, the node capacitance is more affected by temperature, and the raw data of the bottom area node collected by the touch IC scan will be smaller. (c) in Figure 2 is a schematic diagram of the detected node Baseline data in a low temperature (minus 15°C) environment, and the screen of the electronic device has no touch input, as can be seen from (c) in Figure 2, The overall data difference between the Baseline data in the rectangular frame 21b and the Baseline data in the rectangular frame 22b is relatively large, that is, the overall difference in capacitance values between the upper right corner area of the screen and the lower right corner area of the screen is relatively large.

When switching from a low temperature to a high temperature environment, the bottom area of the touch screen will heat up faster than the top area, and the Rawdata of the bottom area node collected by the touch IC scan will be larger. (d) in Figure 2 is a schematic diagram of the detected node Baseline data in a high temperature (50°C) environment, and the screen of the electronic device has no touch input. It can be seen from (d) in Figure 2 that the rectangular frame The overall data difference between the Baseline data in 21c and the Baseline data in the rectangular frame 22c is relatively large, that is, the capacitance values in the upper right corner area of the screen and the lower right corner area of the screen are generally different.

It should be noted that the touch chip (that is, the touch IC) can scan each node of the screen through row scanning or column scanning, obtain the capacitive sensing data (Rawdata) of each node of the screen, and further determine the benchmark Value (Baseline). That is to say, the arrangement of the data in FIG. 2 is consistent with the arrangement order of the nodes on the screen of the electronic device, and there is a corresponding relationship between the area where the data is located in FIG. 2 and the screen area. For example, the area where the rectangular frame 21a in FIG. 2 is located corresponds to the upper right corner area of the screen.

It should be noted that since the Baseline data is determined based on the Rawdata data obtained by scanning the touch IC, the Baseline data can reflect the data characteristics of the corresponding Rawdata data.

According to the above experimental data, it can be seen that 1) the reason for switching from a low-temperature environment to a high-temperature environment is that it is easy to misreport points: the Baseline value in the bottom area of the screen is small in a low-temperature environment, and the node capacitance in the bottom area returns to temperature faster after the low temperature returns to high temperature. The value of Rawdata at the bottom rises rapidly, and the value of diffdata at the bottom of the screen increases to a positive value. At this time, if the touch screen is in the touch state for a long time, the Baseline has not been updated or the update is slow. The diffdata value of the non-touch area rises too high and reaches the reporting threshold, so the key to processing is to include two points:

i. In a low temperature environment, when it is detected that the value of the Baseline plane in the bottom area of the screen decreases as a whole, increase the Baseline update speed in advance to ensure that the Baseline update speed will not lag behind the Rawdata change speed caused by the temperature;

ii. Increase the Noise threshold, and use the row-column average filter algorithm to filter out data lifts caused by temperature changes, so as to avoid false alarm points due to the sudden increase of node data in the bottom area diffdata to the reporting point threshold.

2) Switching from a high temperature environment to a low temperature environment is easy to have no function and low sensitivity. The reason is that the value of the Baseline plane in the bottom area is too large in the high temperature environment. After the high temperature returns to low temperature, the node capacitance in the bottom area cools down faster, and the value in the bottom area of the Rawdata plane drops rapidly. , the diffdata has a negative value in the bottom area of the plane. At this time, if the touch screen is in use or touched for a long time, the Baseline has been in a state of not updating or updating slowly, and the diffdata may have a negative value in a large area, which affects the sensitivity. The processing method includes two points:

i. Switch with low temperature, increase the update speed of Baseline;

ii. Reduce the reporting threshold to avoid problems such as no function of the touch screen and insensitive scribing and clicking due to weakened finger sensing. After the temperature stabilizes and the flatness of the Baseline plane is restored, the reporting threshold will be restored.

An embodiment of the present application provides a method for adjusting screen parameters, which can be applied to electronic devices. FIG. 3 shows a flow chart of the method for adjusting screen parameters provided by the embodiment of the present application. As shown in FIG. 3 , the screen parameter adjustment method provided by the embodiment of the present application may include the following steps 201 to 203:

Step 201: Acquiring first reference data of the screen.

Wherein, the above-mentioned screen includes N areas, and the above-mentioned first reference data includes: a first touch response reference value corresponding to each area, and N is a positive integer.

In the embodiment of the present application, the above-mentioned first reference data may be one frame of reference data of the screen.

In this embodiment of the present application, the above-mentioned one frame of first reference data includes at least one piece of data. Exemplarily, in the case that the screen includes M*N nodes, the above-mentioned first reference data includes M*N node data.

Optionally, in the embodiment of the present application, the above-mentioned first detection data may be benchmark data Baseline, which is used for the current obtained third detection data (Rawdata) when the screen currently receives touch input. Do the difference to get the capacitance difference data (diffdata).

Exemplarily, after acquiring the first reference data of the screen, the screen parameter adjustment device may acquire a frame of third detection data of the screen.

It should be noted that the above capacitance difference data is used to determine the coordinates of the touch point of the touch input.

Optionally, in the embodiment of the present application, the above-mentioned first touch response reference value is the value of the above-mentioned first reference data.

For example, take N areas including area 1 at the lower right corner of the screen and area 2 at the upper right corner as an example. Then the first touch response reference value of area 1 is the touch response reference value of the lower right corner of the screen, and the first touch response reference value of area 2 is the touch response reference value of the upper right corner of the screen.

It should be noted that due to the structure of the electronic device, the capacitive sensing data of the screen area in the lower right corner is more susceptible to the influence of the temperature difference of the external environment than the capacitive sensing data of the screen area in the upper right corner. Therefore, based on these two The sensing data of the area is used to judge the temperature difference outside.

Optionally, in this embodiment of the present application, after acquiring a frame of first benchmark data of the screen, the screen parameter adjustment device may establish a Baseline matrix corresponding to the first benchmark data, so as to calculate or process the benchmark data through the Baseline matrix .

Exemplarily, the above-mentioned Baseline matrix can also be called a Baseline plane, and the Baseline plane can be a rectangular plane, and the benchmark data in the plane corresponds to the benchmark data of the entire area of the screen, and is used to represent a frame of benchmark data of the screen overall volatility.

Exemplarily, the device for adjusting screen parameters may acquire the reference data of the upper right corner area of the Baseline plane, so as to obtain the reference data of the upper right corner area of the screen.

Step 202: Acquiring second reference data of the screen when the first predetermined condition is met.

Wherein, the above-mentioned second reference data includes: a second touch response reference value corresponding to each area.

Wherein, the first reference data is reference data obtained at a first time, and the second reference data is reference data obtained at a second time, and the second time is later than the first time.

In the embodiment of the present application, the above-mentioned first predetermined condition includes: the capacitance sensing value in a frame of third detection data fluctuates, that is, the capacitance sensing value changes as a whole.

Exemplarily, after the screen parameter adjustment device acquires the third detection data, it can obtain the difference data diffdata based on the third detection data and the above-mentioned first reference data, and determine the value of the third detection data by detecting the change amount of the diffdata whether fluctuations occur. Further, if the value of diffdata changes, the value representing the third detection data changes. For example, if the overall diffdata tends to 0, then the numerical value representing the third detection data does not fluctuate; when the overall diffdata data is large, the numerical value representing the third detection data fluctuates.

In the embodiment of the present application, the above-mentioned second reference data may be an updated frame of second reference data. Exemplarily, the above-mentioned first reference data may be currently obtained updated data for the first reference data.

Exemplarily, the screen parameter adjustment may obtain the second reference data of the screen at any time (ie, the second time) after the first reference data of the screen is obtained. Since the benchmark data of the screen can be updated slowly, the second benchmark data acquired at the second time may be different from the first benchmark data acquired before, that is, the second benchmark data acquired at the second time may be updated After the first benchmark data.

It should be noted that after obtaining the first reference data of one frame of the screen, when the user performs touch input, the screen parameter adjustment device will obtain the current capacitive sensing data (ie Rawdata), if external factors such as temperature cause the acquisition If the value of the current capacitive sensing data rises or falls abnormally, the current baseline data (ie, Baseline) will also change accordingly to offset the abnormal value of the capacitive sensing data, so as to obtain a more accurate report of the touch input.

Optionally, in this embodiment of the present application, after acquiring the current capacitive sensing data of the screen, the screen parameter adjustment device may establish a Rawdata matrix corresponding to the Rawdata, so as to calculate or process the capacitive sensing data through the Rawdata matrix.

It should be noted that the aforementioned Rawdata matrix may also be called a Rawdata plane.

Optionally, in the embodiment of the present application, the device for adjusting screen parameters may obtain updated second reference data of a frame when it detects data fluctuations in the current capacitive sensing data (ie, Rawdata).

Exemplarily, the screen parameter adjustment device acquires the current Baseline plane when it detects that the data of the current Rawdata plane fluctuates.

Step 203: Adjust the target parameter of the screen based on the variation between the first touch response reference value and the second touch response reference value corresponding to each area.

Wherein, the above-mentioned target parameters include at least one of the following: an update rate of reference data, a noise threshold, and a response threshold, and the above-mentioned response threshold may be a reporting threshold of a screen.

Optionally, in the embodiment of the present application, the above N areas may include the first area and the second area;

Exemplarily, the above step 203 may include the following steps 203a to 203c:

Step 203a: The screen parameter adjustment device acquires the first variation between the first touch response reference value of the first area and the second touch response reference value of the first area, and the first touch response reference value of the second area The second variation between the value and the second touch response reference value.

Step 203b: The screen parameter adjustment device determines the first value according to the first variation and the second variation.

Step 203c: the screen parameter adjustment device adjusts the target parameter of the screen according to the above-mentioned first value.

Exemplarily, the above-mentioned first area and second area may be symmetrical areas on the screen. For example, the first area is the upper right area of the screen, and the second area is the lower right area of the screen. For another example, the first area is the upper half area of the screen, and the second area is the lower half area of the screen.

Exemplarily, the above-mentioned first change amount may be the difference between the first touch response reference value corresponding to the first area and the second touch response reference value; the above-mentioned second change amount may be the second touch response reference value corresponding to the second area. A difference between a touch response reference value and a second touch response reference value.

Exemplarily, the above-mentioned first numerical value may be a ratio between the above-mentioned first change amount and the above-mentioned second change amount.

Exemplarily, the screen parameter adjustment device may adjust the target parameter of the screen based on the ratio between the above-mentioned change amounts corresponding to each area.

Further optionally, in the embodiment of the present application, the above step 203c may include the following steps 203c1 and 203c2:

Step 203c1: The screen parameter adjustment device determines an adjustment strategy according to the target value range of the first value.

Step 203c2: The screen parameter adjustment device adjusts the target parameter of the screen based on the above adjustment strategy.

Exemplarily, the device for adjusting screen parameters may determine the target value range of the ratio in at least one preset value range, and then adjust the target parameter of the screen. Further, a preset value range corresponds to an adjustment strategy.

In a specific implementation, the screen parameter adjustment device may determine the first difference between the first touch response reference value and the second touch response reference value of the first area, and determine the first touch response reference value of the second area value and the second touch response reference value, then calculate the ratio of the first difference to the second difference, and determine the numerical range of the ratio, and finally, according to the numerical value of the ratio The adjustment strategy corresponding to the range is used to adjust the target parameters of the screen in a targeted manner.

Further optionally, in the embodiment of the present application, the above step 203c1 may include the following step 204a or step 204b:

Step 204a: When the first numerical value is in the first numerical range, determine the adjustment strategy as the first adjustment strategy.

Wherein, the above-mentioned first adjustment strategy includes: adjusting the update rate of the reference data of the screen to the first update rate, and adjusting the noise threshold to the first noise threshold, the above-mentioned first update rate is greater than the update rate before adjustment, and the above-mentioned first The noise threshold is greater than the noise threshold before adjustment.

Step 204b: When the first numerical value is in the second numerical range, determine that the adjustment strategy is the second adjustment strategy.

Wherein, the second adjustment strategy includes: adjusting the update rate of the reference data of the screen to the second update rate, and adjusting the response threshold to the first response threshold, and the first response threshold is smaller than the response threshold before adjustment.

Exemplarily, the apparatus for adjusting screen parameters may determine the adjustment strategy according to the value range of the first value and the magnitudes of the first change amount and the second change amount.

Exemplarily, the above-mentioned first numerical range and the above-mentioned second numerical range can be [Φ, +∞), the above-mentioned first variation (that is, the first difference) can be represented by ΔR1, and the above-mentioned second variation ( That is, the second difference) can be represented by ΔR2, and the above-mentioned first value (ie, the ratio) can be represented by ΔR1/ΔR2.

The following is the adjustment strategy for the target parameters of the screen according to the value range of the first value and the size of the first change amount and the second change amount:

1) When △R1/△R2 is in the interval [-Φ, Φ], the temperature difference representing the current environment is small, and the Baseline is slowly updated with the changing trend of Rawdata;

2) When △R1/△R2 is in the interval [Φ, +∞) and △R1<0, △R2<0, it means that the current ambient temperature is decreasing.

For example, when it is recognized that the current ambient temperature is low temperature, the Baseline update speed is increased in advance to ensure that the low temperature and high temperature Baseline speed can catch up with the Rawdata change speed caused by the temperature; when the current ambient temperature is recognized as high temperature, the Baseline update speed is increased in advance, and reduced Reporting threshold, so as to ensure the sensitivity of the screen and the accuracy of the touch screen in high temperature and low temperature scenes.

Wherein, the above-mentioned one frame of first reference data is: among the above-mentioned N frames of first detection data, one frame of first detection data collected when no touch input from the user is received.

Exemplarily, after the touch IC is powered on or wakes up from sleep, it scans to obtain several frames of first detection data (Rawdata), and when it detects that a certain frame of Rawdata is relatively stable and no touch occurs, the frame of Rawdata is determined as the first reference Data (Baseline), and establish a Baseline plane with a frame of Rawdata with higher flatness.

Optionally, in the embodiment of the present application, after the above step 201, the screen parameter adjustment method provided in the embodiment of the present application further includes the following steps B1 to B3:

Step B1: Obtain a frame of third detection data of the screen.

Step B2: Determine the target difference between the capacitive sensing value in the above-mentioned frame of third detection data and the touch response reference value in the currently acquired frame of detection data.

Step B3: Based on the target difference, determine whether a touch input is received on the screen.

Wherein, the above-mentioned third detection data includes: a capacitance sensing value in the screen.

Exemplarily, after the screen parameter adjustment device establishes the Baseline plane, it can scan the screen nodes through the touch IC to obtain the third detection data of the screen.

Exemplarily, the above-mentioned frame of detection data includes: currently acquired baseline data (Baseline).

Exemplarily, the above-mentioned target difference is used to characterize the variation of the capacitance data of the screen.

Exemplarily, the apparatus for adjusting screen parameters may determine whether a touch input is currently received based on the aforementioned target difference. For example, in a case where the above-mentioned target difference is greater than the reporting threshold, it is determined that a touch input is currently received.

Further optionally, in the embodiment of the present application, the above step B3 may include the following step C1:

Step C1: When it is determined that the screen receives a touch input, in response to the touch input, determine the coordinates of the touch point corresponding to the touch input according to the target difference.

Exemplarily, the device for determining the screen parameter may judge whether the value of the currently sampled third detection data fluctuates according to the capacitance difference data (diffdata).

Exemplarily, the above capacitance difference data is determined based on the above third detection data and updated baseline data (Baseline).

It should be noted that if the screen does not receive touch input, under normal circumstances, the currently detected capacitive sensing value (Rawdata) of the screen is basically consistent with the baseline value (Baseline), that is, the difference between the capacitive sensing value and the baseline value The value will tend to 0 (that is, the 0 plane), and in the case of a sudden change in the ambient temperature (for example, from an environment of 25°C to an environment of 5°C), it will have an impact on the currently acquired capacitive sensing value. In some cases, the difference between the capacitive sensing value and the reference value is relatively large, and it is considered that the currently acquired capacitive sensing value generates data fluctuations.

The following is an example of an implementation step of the screen parameter adjustment method provided by the embodiment of the present application, as shown in FIG. 4, which is a flow chart of the screen parameter processing method provided by the embodiment of the present application:

Take baseline data (first benchmark data, second benchmark data) as Baseline, and detection data (first detection data, third detection data) as Rawdata as an example.

Step1: After the touch IC is powered on or wakes up from sleep, scan to obtain several frames of Rawdata. When it is detected that the Rawdata is relatively stable and no touch occurs, an initial Baseline plane is established with a frame of Rawdata with higher flatness;

Step2: Calculate the mean value R10 of the Baseline of M*N nodes in the lower right corner area of the initial Baseline plane, and calculate the mean value R20 of the Baseline of the symmetrical area in the upper right corner. Taking the touch module of 18Tx*32Rx as an example, M is the number of rows and can be 5, and N is The number of columns can be 9;

Step3: After establishing the initial Baseline plane, the touch IC scans to obtain Rawdata, calculates the current diffdata data, and obtains the diffdata plane after filtering;

Setp4: Detect whether there is a touch on the diffdata plane, if so, calculate the touch coordinates through a series of algorithms, and then report the point, if no touch occurs, judge whether the Rawdata sampled in Step3 has changed through the diffdata plane, that is, whether there is a data offset , if there is no change, return to Setp3 to start the next frame of Rawdata sampling, and enter Step5 if there is data offset;

Step5: After detecting that the data of the current Rawdata plane has changed, obtain the current Baseline plane, calculate the mean value R11 of the Baseline of the M*N nodes in the lower right corner area of the current Baseline plane and the mean value R21 of the Baseline of the symmetrical area in the upper right corner, and calculate the current Baseline plane The difference between the mean value of the lower right corner area of the initial Baseline plane and the mean value of the lower right corner area of the initial Baseline plane △R1=R11-R10, and calculate the mean value of the upper right corner area of the current Baseline plane and the mean value of the upper right corner area of the initial Baseline plane The difference between △R2=R21-R20;

Step6: Determine the relationship between the ratio △R1/△R2 between the above difference △R1 and the difference △R2 and the preset threshold Φ, and then enter different processing procedures:

1) When △R1/△R2 is in the interval [-Φ, Φ], it indicates that although there is a data offset between the Rawdata and the Baseline plane, the offset degree is small, that is, the current ambient temperature difference is small, and it slowly changes with the Rawdata Trend update Baseline;

2) When △R1/△R2 is in the interval [Φ, +∞) and △R1<0, △R2<0, it indicates that the current ambient temperature is decreasing. In order to avoid the false jump point of the touch screen when switching from low temperature to high temperature, increase the Baseline Update speed, and increase the Noise threshold, and use the mean filtering algorithm for data filtering;

3) When △R1/△R2 is in the [Φ, +∞) interval and △R1>0, △R2>0, it is considered that the current ambient temperature is rising, in order to avoid switching from high to low temperature, the touch screen has no function and low sensitivity , increase the speed of Baseline update, and reduce the reporting threshold;

4) If neither △R1/△R2 satisfies (1)(2)(3), then it is considered that the currently obtained Baseline is wrong, and return to Step 1 to obtain Rawdata to establish a Baseline.

It should be noted that, considering that there will be a gap between the far and near ends of the full-screen capacitive nodes of the touch capacitive screen, the value of Φ can be 5, and return to Setp3 after processing to start the next frame of Rawdata sampling.
