Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The technical scheme provided by the embodiment of the disclosure relates to a terminal, which can be a mobile phone, a tablet computer, a smart watch and other devices provided with a touch screen, and the embodiment of the disclosure does not limit the terminal. In the related art, a touch screen arranged on a terminal, that is, a touch display module is provided with a plurality of rows of sensor groups, each row of sensor group includes a plurality of touch sensors, and the touch display module acquires a detection result through detection data detected by each touch sensor. If the touch display module is abnormal, the detection data detected by the touch sensor may be deviated, which affects the detection result of the touch display module, and the user experience is poor due to the serious possible occurrence of misoperation or touch failure and other results. According to the technical scheme, the difference data of the touch sensor which detects the pressing signal and the difference data of the touch sensor which does not detect the pressing signal are corrected through the first preset coefficient and the second preset coefficient, so that the deviation caused by the conditions of unstable grounding, noise or interference and the like can be filtered, the accuracy of the detection data detected by the touch sensor is improved, and the user experience is further improved.

Fig. 1a is a flowchart illustrating a touch anomaly adjustment method according to an exemplary embodiment, where the method is applied to a touch display device, which may be disposed in a terminal, as shown in fig. 1b, the touch display device 10 is provided with a plurality of sensor groups 10a, and each sensor group 10a includes a plurality of touch sensors 10a 1. As shown in fig. 1a, the touch anomaly adjustment method includes the following steps 101 to 103:

in step 101, when it is determined that there is a reference sensor group in which an abnormality occurs in the multiple sensor groups, a touch sensors that do not detect a pressing signal and B touch sensors that detect a pressing signal are determined from difference data of each of the multiple touch sensors included in the reference sensor group.

The difference data is a difference value between sampling data of the touch sensors and reference data of the touch display device, the reference sensor group is any one of multiple sensor groups, A and B are integers greater than or equal to 0, and the sum of A and B is equal to the number value of the touch sensors included in the reference sensor group.

For example, as shown in fig. 1c, the touch display device 10 may include a glass cover plate 10b, an optical adhesive layer 10c, a polarizing layer 10d, a color filter layer 10e, a multi-column sensor group 10a, a thin film transistor layer 10f and a backlight module 10g, the touch display device 10 is clamped in a module metal frame 10h, the module metal frame 10h is connected with a middle frame 10i in a matching manner, the multi-column sensor group 10a included in the touch display device 10 is electrically connected with the module metal frame 10h through a Flexible Printed Circuit (FPC) and a conductive adhesive, and the module metal frame 10h is electrically connected with the middle frame 10i through a conductive foam. When analyzing the grounding condition of the touch display device 10, the touch sensor 10a1 included in the multi-column sensor group 10a and other conductors included in the touch display device 10 may be equivalent to a capacitor Cs, and grounding is achieved through the capacitor Cs; the connection between the touch sensor 10a1 and the module metal frame 10h is equivalent to a capacitor Cb, the connection between the FPC and the conductive adhesive is equivalent to a resistor R1, and the grounding is realized through the capacitor Cb and the resistor R1; the connection between the touch sensor 10a1 and the module metal frame 10h is equivalent to a capacitor Cb, the connection between the module metal frame 10h and the middle frame 10i is equivalent to a resistor R2 through the conductive foam, and the grounding is realized through the capacitor Cb and the resistor R2, and a grounding equivalent circuit of any touch sensor 10a1 can be as shown in fig. 1 d. When the touch display device 10 is in operation, the plurality of touch sensors 10a1 arranged therein may be continuously scanned at preset time intervals, sample data of the plurality of touch sensors 10a1 is obtained, a difference value between the sample data of each touch sensor 10a1 and reference data, that is, difference value data, is determined as detection data of each touch sensor 10a1, and whether a user operation exists or not is determined according to the size of the detection data of each touch sensor 10a 1. For example, if the detection data of several touch sensors 10a1 among the plurality of touch sensors 10a1 provided in the touch display device 10 is greater than or equal to the second preset threshold, it is determined that the user operation exists, the areas corresponding to the several touch sensors 10a1 are determined as the click positions of the fingers of the user, and the user operation is fed back according to the icons or the content displayed at the click positions.

As can be seen from fig. 1d, if the grounding is good, the resistances of the resistor R1 and the resistor R2 are small, and may be smaller than 10 ohms in general, and at this time, the average value of the sampling data of all the touch sensors 10a1 disposed in the touch display device 10 may be used as the reference data of the touch display device 10. When there are several touch sensors 10a1 with unstable grounding in a certain scanning, the resistances of the resistor R1 and the resistor R2 corresponding to the touch sensor 10a1 with unstable grounding will increase instantaneously, which causes the impedance of the series circuit of the capacitor Cb and the resistor R (the resistor R is the parallel resistor of the resistor R1 and the resistor R2) to increase instantaneously, and at this time, the sampled data detected by the touch sensor 10a1 becomes larger, which further causes the forward increase of the difference data of the touch sensor 10a1 with unstable grounding in the scanning process, that is, the difference between the sampled data and the reference data becomes larger. If the touch display device 10 uses the difference data with deviation acquired by the touch sensors 10a1 with unstable grounding as the detection data in this scanning, a ghost point of the touch display device 10 may be mistakenly reported, that is, a user operation is detected under the condition that the user is not operating, which may seriously cause the touch display device 10 to enter a palm suppression mode, that is, the entire touch display device 10 is disabled (frozen), and further cause the user to be unable to continue using the device. Meanwhile, since the touch display device 10 adjusts the reference data according to the average value of the sampling data of the touch sensors 10a1 acquired in the multiple scanning processes, if the number of the touch sensors 10a1 with unstable grounding is large, the reference data of the touch display device 10 is increased along with the increase of the scanning times. Thus, when the grounding recovery of the touch display device 10 is good, even if there is a user operation, that is, the sampled data of the touch sensor 10a1 in the corresponding area is large, the difference between the sampled data of the touch sensor 10a1 in the area and the reference data is small, that is, the difference data of the touch sensor 10a1 in the area is small, and even a negative value occurs, because the reference data is too large. At this time, taking the difference data of the touch sensor 10a1 in the area as the detection data may cause the detection data of the touch sensor 10a1 in the area to be smaller than the second preset threshold, that is, the touch display device 10 cannot detect the user operation in the area, which greatly affects the user experience.

In practical applications, the abnormality of the touch sensor 10a1 may occur not only when the grounding is unstable, but also when the touch display device 10 encounters noise or interference.

As described above, the touch display device 10 can correct the difference data of the touch sensor 10a1 when detecting that the ground of the touch sensor 10a1 is unstable, that is, when an abnormality occurs, and then use the corrected data as the detection data, thereby improving the detection accuracy of the touch display device 10.

For example, the touch display device 10 may divide the acquired sample data of the plurality of touch sensors 10a1 by a plurality of columns of sensor groups 10a each time the plurality of touch sensors 10a1 are set by the scanner, acquire the difference data of each touch sensor 10a1 included in each column of sensor groups 10a, that is, acquire the difference between the sample data of each touch sensor 10a1 included in each column of sensor groups 10a and the reference data of the touch display device 10, and determine whether an abnormality occurs in each column of sensor groups 10a according to the difference data of each touch sensor 10a 1.

Specifically, since the sampling data of the touch sensor 10a1 is stable when no abnormality occurs, the touch display device 10 may preset a first preset threshold according to the difference data of each touch sensor 10a1 when no abnormality occurs, for example, the first preset threshold may be 20. Then, it is determined whether N touch sensors having difference data greater than or equal to a first preset threshold exist among the touch sensors included in each column of the sensor group 10a, and when N touch sensors having difference data greater than or equal to the first preset threshold exist among the touch sensors included in the sensor group 10a, it is determined that the sensor group 10a is abnormal. Taking a reference sensor group as an example, the reference sensor group is any one of multiple sensor groups 10a arranged in the touch display device 10, and the touch display device 10 may first obtain difference data of multiple touch sensors included in the reference sensor group, and then determine whether N touch sensors having difference data greater than or equal to a first preset threshold exist in the multiple touch sensors. If N touch sensors having difference data greater than or equal to a first preset threshold exist in the plurality of touch sensors included in the reference sensor group, it may be determined that the reference sensor group is abnormal. In practical applications, since the difference data may also have a negative value, the touch display device 10 may also determine whether there are N touch sensors having an absolute value of the difference data greater than or equal to the first preset threshold among the touch sensors included in the reference sensor group, and if there are N touch sensors having an absolute value of the difference data greater than or equal to the first preset threshold among the touch sensors, it may be determined that the reference sensor group is abnormal.

Alternatively, because the difference data of the touch sensor 10a1 in the touch area may be much larger than the first preset threshold when the user's finger touches, it may not be abnormal that the difference data of the touch sensor 10a1 is larger than or equal to the first preset threshold, and in order to avoid misinterpretating the normal operation of the user as abnormal, the touch display device 10 may further set a second preset threshold, where the first preset threshold is smaller than the second preset threshold, and the second preset threshold is used to limit a minimum value of the user operation that can be detected by the touch display device 10, and for example, the second preset threshold may be 200. If the difference data of the touch sensor 10a1 is smaller than the first preset threshold, it indicates that the touch sensor 10a1 is not abnormal; if the difference data of the touch sensor 10a1 is greater than or equal to the first preset threshold value and less than or equal to the second preset threshold value, it is determined that an abnormality occurs; if the difference data of the touch sensor 10a1 is greater than the second predetermined threshold, it indicates that the touch sensor 10a1 detects the user operation. Taking the reference sensor group as an example, the touch display device 10 may first obtain difference data of a plurality of touch sensors included in the reference sensor group, and then determine whether N touch sensors having difference data greater than or equal to a first preset threshold and less than or equal to a second preset threshold exist in the plurality of touch sensors. If there are N touch sensors having difference data greater than or equal to a first preset threshold and less than or equal to a second preset threshold among the plurality of touch sensors included in the reference sensor group, it may be determined that the reference sensor group is abnormal. In practical applications, because the difference data may also have a negative value, the touch display device 10 may also determine whether there are N touch sensors having an absolute value of the difference data greater than or equal to the first preset threshold and less than or equal to the second preset threshold among the touch sensors included in the reference sensor group, and if there are N touch sensors having an absolute value of the difference data greater than or equal to the first preset threshold and less than or equal to the second preset threshold among the touch sensors, it may be determined that the reference sensor group has an abnormality.

In practical application, since it is determined whether the accuracy of the abnormality is not high only by the number, and a false determination may occur, when it is determined whether the abnormality exists in the reference sensor group, it may be further determined whether a comparison difference between difference data of M pairs of adjacent touch sensors in a plurality of touch sensors included in the reference sensor group is smaller than or equal to a third preset threshold, where the third preset threshold may be 12. Specifically, the touch display device 10 may first obtain difference data of a plurality of touch sensors included in the reference sensor group, and then determine whether N touch sensors having difference data greater than or equal to a first preset threshold exist in the plurality of touch sensors. If N touch sensors with difference data larger than or equal to a first preset threshold exist in the plurality of touch sensors, sequentially obtaining the comparison difference of the difference data of adjacent touch sensors in the plurality of touch sensors included in the reference sensor group, namely obtaining the difference of the difference data of the adjacent touch sensors in the plurality of touch sensors included in the reference sensor group, and then determining whether the comparison difference of the difference data of the adjacent touch sensors in the plurality of touch sensors has a comparison difference of M pairs of difference data of the adjacent touch sensors smaller than or equal to a third preset threshold. And if the comparison difference of the difference value data of M pairs of adjacent touch sensors in the plurality of touch sensors is smaller than or equal to a third preset threshold value, determining that the reference sensor group is abnormal. In practical applications, since the difference data may also have a negative value, the touch display device 10 may also determine whether the absolute value of the comparison difference between M pairs of difference data of adjacent touch sensors is less than or equal to a third preset threshold when determining that there are N touch sensors having an absolute value greater than or equal to the first preset threshold among the touch sensors included in the reference sensor group. And if the absolute value of the comparison difference of the difference data of M pairs of adjacent touch sensors in the plurality of touch sensors is smaller than or equal to a third preset threshold, determining that the reference sensor group is abnormal.

For example, when it is determined that an abnormality occurs in the reference sensor group, the touch display device 10 may determine, according to the difference data of each of the touch sensors included in the reference sensor group, a touch sensors that do not detect a press signal and B touch sensors that detect a press signal, that is, a touch sensor that has a difference data smaller than or equal to a second preset threshold among the touch sensors included in the reference sensor group may be determined as a touch sensor that does not detect a press signal, and a touch sensor that has a difference data larger than the second preset threshold among the touch sensors may be determined as B touch sensors that detect a press signal.

In step 102, the difference data of the a touch sensors are corrected according to the difference data of the a touch sensors and a first preset coefficient, and detection data of the a touch sensors are obtained.

For example, the touch display device 10 may preset a first preset coefficient and a second preset coefficient, where the first preset coefficient is used to correct difference data of a touch sensor where an abnormality occurs and a pressing signal is not detected, and the second preset coefficient is used to correct difference data of a touch sensor where an abnormality occurs and a pressing signal is detected, for example, the first preset coefficient may be 1/10, and the second preset coefficient may be 3/4.

Specifically, after determining the a touch sensors that do not detect the pressing signal, the difference data of the a touch sensors may be corrected according to the difference data of the a touch sensors and the first preset coefficient, that is, the product of the difference data of the a touch sensors and the first preset coefficient is determined as the detection data of the a touch sensors.

In step 103, the difference data of the B touch sensors are corrected according to the difference data of the B touch sensors and a second preset coefficient, so as to obtain the detection data of the B touch sensors.

For example, after B touch sensors that detect the pressing signal are determined, the difference data of the B touch sensors may be corrected according to the difference data of the B touch sensors and the second preset coefficient, that is, the product of the difference data of the B touch sensors and the second preset coefficient is determined as the detection data of the B touch sensors, respectively.

According to the correction process of the reference sensor group, all abnormal sensor groups in the plurality of sensor groups set in the touch display device 10 can be corrected in sequence, that is, the difference data of the plurality of touch sensors included in the sensor group which is not abnormal is used as the detection data of the abnormal sensor groups, and the difference data of the plurality of touch sensors included in the sensor group which is abnormal is used as the detection data of the abnormal sensor groups according to the correction data of the first preset coefficient or the second preset coefficient, so that the touch display device 10 can determine the detection result according to the finally obtained detection data, that is, determine whether the user operation exists or not, or determine the motion track of the user operation, and the like, and improve the detection precision of the touch display device 10. Meanwhile, the algorithm corrects the difference data of the touch sensor with the abnormality through software, so that the hardware of the touch display device 10 is prevented from being maintained when the abnormality occurs, and the after-sale cost is reduced.

According to the technical scheme, the difference data of the touch sensor which detects the pressing signal and the difference data of the touch sensor which does not detect the pressing signal are corrected through the first preset coefficient and the second preset coefficient, so that the deviation caused by the conditions of unstable grounding, noise or interference and the like can be filtered, the accuracy of the detection data detected by the touch sensor is improved, and the user experience is further improved.

In one embodiment, as shown in fig. 1e, the method further comprises steps 104 to 107:

in step 104, when the pressing signals detected by the a touch sensors included in the reference sensor group disappear, the difference data of the plurality of touch sensors included in the reference sensor group is acquired for G times continuously.

Wherein G is an integer greater than or equal to 1.

In step 105, it is determined whether an abnormality of the reference sensor group continuously occurs according to the difference data of the plurality of touch sensors included in the reference sensor group obtained for G consecutive times.

In step 106, if the reference sensor group is continuously abnormal, reference data is obtained according to difference data of a plurality of touch sensors included in the reference sensor group obtained for G consecutive times.

In step 107, the reference data of the touch display device is updated according to the reference data.

For example, in order to avoid the waste of terminal computing resources caused by performing correction after each scanning, the touch display device may calibrate the reference data when it is determined that the user operation is completed and an abnormality continues to occur, so that the touch display device may not perform correction to obtain a correct detection result in the next user operation.

Taking the reference sensor group as an example, the touch display device may determine in real time whether the pressing signals detected by a touch sensors included in the reference sensor group disappear through scanning, that is, whether the operation of the user is completed. If the pressing signals detected by the a touch sensors included in the reference sensor group disappear, that is, the difference data of the a touch sensors included in the reference sensor group are all smaller than the second preset threshold value, the difference data of the multiple touch sensors included in the reference sensor group can be obtained through continuous scanning for G times, and whether the reference sensor group is abnormal in the scanning for G times or not is determined, that is, whether the reference sensor group is abnormal continuously or not is determined. If the reference sensor group is continuously abnormal, reference data can be obtained according to difference data of the touch sensors included in the reference sensor group obtained in the consecutive G times, and the datum data of the touch display device can be updated according to the reference data. Specifically, if the reference sensor group is continuously abnormal, the touch display device may obtain an average value of difference data of a plurality of touch sensors included in the reference sensor group obtained in G consecutive times, and then set the average value as the reference data of the touch display device.

In the technical scheme provided by the embodiment of the disclosure, through calibration of the reference data, waste of terminal computing resources caused by correction after each scanning of the touch display device can be avoided, and the standby time of the touch display device is prolonged.

The implementation is described in detail below by way of several embodiments.

Fig. 2 is a flowchart illustrating a touch anomaly adjustment method according to an exemplary embodiment, where an execution subject is a touch display device, the touch display device is provided with a plurality of sensor groups, each sensor group includes a plurality of touch sensors, and the touch display device can be disposed on a terminal, as shown in fig. 2, including the following steps:

in step 201, sampling data and reference data of each touch sensor set by the touch display device are acquired.

In step 202, difference data of each touch sensor is obtained according to the sampling data and the reference data of each touch sensor.

In step 203, determining whether the reference sensor group includes N touch sensors having difference data greater than or equal to a first preset threshold; if not, go to step 204; if so, go to step 205.

In step 204, it is determined that the reference sensor group is not abnormal, and the process ends.

In step 205, it is determined whether a comparison difference between upper and lower values of difference data of M pairs of adjacent touch sensors in a plurality of touch sensors included in the reference sensor group is smaller than or equal to a third preset threshold; if not, go to step 204; if yes, go to step 206.
