In order to make the objects, technical solutions and advantages of the present disclosure more apparent, the technical solutions of the present disclosure will be described clearly and completely below with reference to the accompanying drawings of the present disclosure. It is to be understood that the described embodiments are only a few embodiments of the present disclosure, and not all embodiments.

To maintain the following description of the present disclosure clear and concise, detailed descriptions of known functions and known components are omitted from the present disclosure.
For the purpose of facilitating an understanding of the present disclosure, a detailed description of one of the detection methods disclosed in the present disclosure will be provided first.
A first aspect of the present disclosure provides a detection method, fig. 1 shows a flowchart of the detection method, and specific steps include the following S101 to S103:
s101, a first test value of a first touch sensor and a second test value of a second touch sensor are obtained from the touch sensors to be detected, wherein the first touch sensor and the second touch sensor are adjacent in a touch display panel.
In the specific detection process, the test signal is transmitted to the touch screen to be detected through the touch integrated circuit, and specifically transmitted to each touch sensor to be detected included in the touch screen to be detected, wherein the test signal includes a preset current and voltage touch screen and the like. Each touch sensor to be detected feeds back aiming at the test signal and returns the feedback signal to the touch integrated circuit; thereafter, the touch integrated circuit transmits the received feedback signals to a converter, which converts each of the received feedback signals into a decimal test value and transmits each of the test values to a processor or processing device or the like.
Here, the touch sensor to be detected is a touch sensor satisfying a predetermined condition, wherein the predetermined condition includes: the test value obtained by the touch sensor based on the test signal is within a predetermined range. Specifically, the detection process is performed on the normal touch sensors in advance to obtain the test values corresponding to the normal touch sensors, a reference value is determined based on the test values corresponding to the normal touch sensors, for example, an average value of the test values corresponding to the normal touch sensors is used as a reference value, and a predetermined range is determined based on the reference value, for example, if the determined reference value is 5, the predetermined range corresponding to the reference value is determined to be [4.5, 5.5], and the like. On the basis, the detection process is executed on all the touch sensors to be detected, after a test value corresponding to each touch sensor to be detected is obtained, the test values within a preset range are screened out, and the touch sensors corresponding to the test values within the preset range are used as the touch sensors to be detected; then, the detection method disclosed by the invention is used for detecting the touch sensor to be detected, namely, carrying out secondary detection on the touch sensor in the touch screen to be detected, so as to improve the detection accuracy.
S102, determining a first span value based on the first test value and the second test value.
After the first test value and the second test value are obtained, the first test value and the second test value are calculated to obtain a first span value.
The span value is used for indicating the difference degree of the first test value and the second test value, so that the difference degree of the first touch sensor and the second touch sensor can be determined.
Specifically, the specific steps of determining the first span value based on the first test value and the second test value may refer to fig. 2, and specifically include:
s201, determining the absolute value of the difference value between the first test value and the second test value.
S202, a first span value is determined based on the ratio of the absolute value of the difference value to the first test value.
Fig. 3 shows a test value corresponding to each touch sensor in the touch screen to be detected, and the distribution of the test values corresponds to the distribution of the touch sensors. It should be noted that the test values shown in fig. 3 are only used to assist those skilled in the art to understand the embodiments of the present disclosure, and are not values obtained by actually converting the feedback signal by the converter.
For example, in fig. 3, 4 is a first test value, 6 is a second test value, 4 corresponds to the first touch sensor, and 6 corresponds to the second touch sensor. Firstly, calculating the absolute value of the difference between the first test value and the second test value, namely the absolute value of the difference between 4 and 6 is 2; then, determining a first span value based on a ratio of the absolute value of the difference to the first test value, specifically, taking the absolute value of the difference as a dividend, taking the first test value as a divisor, and calculating to obtain a quotient as a first span value, that is, 2/4 obtains 0.5, where the first span value is 0.5; the absolute value of the difference may also be used as a dividend, the first test value is used as a divisor, and the percentage of quotient conversion obtained by calculation is used as a first span value, that is, 2/4 × 100% obtains 50%, and the first span value is 50% at this time, which is not specifically limited in this embodiment of the disclosure.
Of course, 6 may be used as the first test value, 4 may be used as the second test value, and then 6 corresponds to the first touch sensor and 4 corresponds to the second touch sensor.
S103, determining abnormal conditions of the first touch sensor and the second touch sensor based on the first span value.
After the first span value is determined, whether the first touch sensor and the second touch sensor are abnormal or not is determined according to the first span value. Specifically, fig. 4 shows a method for determining an abnormal condition of the first touch sensor and the second touch sensor based on the first span value, wherein the specific steps are as follows:
s401, detecting whether the first span value is larger than a preset span value.
S402, determining that the first touch sensor and the second touch sensor are abnormal when the first span value is larger than the preset span value.
Considering that the difference degree between two adjacent touch sensors is large, the user may have the situations of touch dislocation, touch insensibility and the like in the process of using the touch screen, and therefore, the difference degree between two adjacent touch sensors needs to be limited within a certain range to avoid the situations of touch dislocation, touch insensibility and the like of the touch screen. Specifically, the predetermined span value is determined based on the historical test data, and the two adjacent touch sensors do not cause the situations of touch dislocation, touch insensibility and the like of the touch screen when the difference degree corresponding to the predetermined span value exists.
Further, after the first span value is determined, the first span value is compared with a preset span value, and if the first span value is larger than the preset span value, it is determined that the first touch sensor and the second touch sensor are abnormal.
Here, it is considered that there may be a case where the detection result is inaccurate when only the first span value calculation is performed, for example, when 6 is taken as the first test value and 4 is taken as the second test value in a case where the predetermined span value is 35%, the calculated first span value is [ (| 6-4 |/6) × 100% ] — 33.33%; when 4 is taken as the first test value and 6 as the second test value, the calculated first span value is [ (| 4-6 |/4) × 100% ] -50%; at this time, it may cause a normal touch sensor to be determined as abnormal. Therefore, the embodiment of the present disclosure further provides the detection method shown in fig. 5 to further improve the detection accuracy, where the detection method in fig. 5 includes steps S501 to S505, which are specifically as follows:
s501, a first test value of a first touch sensor and a second test value of a second touch sensor are obtained from the touch sensors to be detected.
In the same process as S101, a first test value of a first touch sensor and a second test value of a second touch sensor in the touch sensors to be detected adjacently are obtained.
S502, determining a first span value based on the first test value and the second test value.
And S102, after the first test value and the second test value are obtained, calculating the first test value and the second test value to obtain a first span value.
S503, determining a second span value based on a ratio of the absolute value of the difference to the second test value.
After the first span value is obtained through calculation, a second span value is further determined based on a ratio of an absolute value of a difference value between the first test value and the second test value to the second test value, the absolute value of the difference value can be used as a dividend, the second test value is used as a divisor, and a quotient is obtained through calculation and is used as the second span value; the absolute value of the difference value can be used as a dividend, the second test value can be used as a divisor, the percentage of quotient conversion is calculated to be used as a second span value, and the like, as long as the type of the quotient conversion is consistent with that of the first span value.
For example, taking 6 as a first test value and 4 as a second test value, the first span value calculated is [ (| 6-4 |/6) × 100% ] -33.33%, and the second span value calculated is [ (| 4-6 |/4) × 100% ] -50%. Of course, if 4 is taken as the first test value and 6 as the second test value, the first span value calculated is [ (| 4-6 |/4) × 100% ] -50%, and the second span value calculated is [ (| 6-4|/6 × 100% ] -33.33%.
S504, whether the first span value is larger than a preset span value or not is detected, and whether the second span value is larger than the preset span value or not is detected.
After the first span value and the second span value are determined, comparing the first span value with a preset span value, and judging whether the first span value is greater than the preset span value; and comparing the second span value with the preset span value to judge whether the second span value is greater than the preset span value.
And S505, determining that the first touch sensor and the second touch sensor are abnormal under the condition that the first span value and the second span value are both larger than a preset span value.
Here, when both the first span value and the second span value are greater than the predetermined span value, it is determined that both the first touch sensor and the second touch sensor are abnormal, which is higher in accuracy than when the first span value is greater than the predetermined span value, it is determined that both the first touch sensor and the second touch sensor are abnormal.
Of course, when the abnormal conditions of the first touch sensor and the second touch sensor are actually determined, the abnormal conditions can be determined according to the above-mentioned manner, that is, when the first span value is greater than the predetermined span value, it is determined that the first touch sensor and the second touch sensor are abnormal; or determining that the first touch sensor and the second touch sensor are abnormal under the condition that the first span value and the second span value are both larger than the preset span value. Here, in consideration of the fact that only one of the first span value and the second span value is greater than the predetermined span value, it may be determined that the first touch sensor is normal and the second touch sensor is abnormal when the first span value is greater than the predetermined span value and the second span value is less than the predetermined span value; and under the condition that the first span value is smaller than the preset span value and the second span value is larger than the preset span value, determining that the first touch sensor is abnormal and the second touch sensor is normal. Thus, the accuracy of detection can be improved.
In a specific implementation, multiple touch sensors may also be detected simultaneously, for example, a first test value of a first touch sensor and a second test value of multiple second touch sensors are obtained, where each second touch sensor is adjacent to the first touch sensor, as shown in fig. 6, a denotes the first touch sensor, and B, C, D, E denotes the second touch sensor; again, as shown in figure 7, the "return" shape, a identifies the first touch sensor, B, C, D, E, F, G, H, I each identifies the second touch sensor, etc.; as long as it is satisfied that the first touch sensor is adjacent to the second touch sensor.
After all the touch sensors in the whole touch screen to be detected are detected, determining the abnormal condition of the touch screen based on the number, the positions and the like of the abnormal touch sensors; for example, when the number of the abnormal touch sensors is larger than a preset threshold, it is determined that the touch screen is abnormal; determining that the touch screen is abnormal and the like under the condition that the position of the abnormal touch sensor is within a preset range; the embodiment of the present disclosure is not particularly limited to this.
Further, after determining the abnormal conditions of all the touch sensors in the touch screen to be detected, the first touch sensor and the second touch sensor in the abnormal state may be marked. As shown in fig. 8, it is determined that the touch sensors corresponding to the test values 4 and 6 are both abnormal based on the above-mentioned detection method, and therefore, the areas corresponding to 4 and 6 may be filled with colors to be distinguished from other areas, so that an observer can easily distinguish a normal touch sensor from an abnormal touch sensor when the marked first touch sensor and/or second touch sensor is displayed.
It should be noted that, in fig. 8, the color filled in the area corresponding to 4 is different from the color filled in the area corresponding to 6, and of course, the color may be the same when actually performing the marking; note that, as shown in fig. 9, when the touch sensor corresponding to 6 is determined to be abnormal, the area corresponding to 6 may be marked with "r" or the like, as long as the normal touch sensor can be distinguished from the abnormal touch sensor, and the embodiment of the present disclosure is not particularly limited to this.
The method and the device can effectively detect whether the adjacent touch sensors have large difference, avoid the condition that the touch screen is abnormal (for example, touch dislocation/touch cannot be sensed) due to the large difference between the adjacent touch sensors, and further improve the accuracy of detection of the touch sensors.
Based on the same inventive concept, the second aspect of the present disclosure further provides a detection apparatus corresponding to the detection method, and since the principle of the apparatus in the present disclosure for solving the problem is similar to the detection method in the present disclosure, the implementation of the apparatus may refer to the implementation of the method, and repeated details are not repeated.
Referring to fig. 10, the detecting device includes:
the obtaining module 1001 is configured to obtain a first test value of a first touch sensor and a second test value of a second touch sensor from touch sensors to be detected, where the first touch sensor and the second touch sensor are adjacent to each other in a touch display panel.
In the specific detection process, the test signal is transmitted to the touch screen to be detected through the touch integrated circuit, and specifically transmitted to each touch sensor to be detected included in the touch screen to be detected, wherein the test signal includes a preset current and voltage touch screen and the like. Each touch sensor to be detected feeds back aiming at the test signal and returns the feedback signal to the touch integrated circuit; thereafter, the touch integrated circuit transmits the received feedback signals to a converter, which converts each of the received feedback signals into a decimal test value and transmits each of the test values to a processor or processing device or the like.
Here, the touch sensor to be detected is a touch sensor satisfying a predetermined condition, wherein the predetermined condition includes: the test value obtained by the touch sensor based on the test signal is within a predetermined range. Specifically, the detection process is performed on the normal touch sensors in advance to obtain the test values corresponding to the normal touch sensors, a reference value is determined based on the test values corresponding to the normal touch sensors, for example, an average value of the test values corresponding to the normal touch sensors is used as a reference value, and a predetermined range is determined based on the reference value, for example, if the determined reference value is 5, the predetermined range corresponding to the reference value is determined to be [4.5, 5.5], and the like. On the basis, the detection process is executed on all the touch sensors to be detected, after a test value corresponding to each touch sensor to be detected is obtained, the test values within a preset range are screened out, and the touch sensors corresponding to the test values within the preset range are used as the touch sensors to be detected; then, the detection method disclosed by the invention is used for detecting the touch sensor to be detected, namely, carrying out secondary detection on the touch sensor in the touch screen to be detected, so as to improve the detection accuracy.
A first determining module 1002, configured to determine a first span value based on the first test value and the second test value.
After the first test value and the second test value are obtained, the first test value and the second test value are calculated to obtain a first span value.
The span value is used for indicating the difference degree of the first test value and the second test value, so that the difference degree of the first touch sensor and the second touch sensor can be determined.
A second determining module 1003, configured to determine an abnormal condition of the first touch sensor and the second touch sensor based on the first span value.
After the first span value is determined, whether the first touch sensor and the second touch sensor are abnormal or not is determined according to the first span value.
In yet another embodiment, the first determining module 1002 includes:
a first determination unit for determining an absolute value of a difference between the first test value and the second test value;
a second determination unit for determining the first span value based on a ratio of the absolute value of the difference to the first test value.
For example, if 4 is the first test value and 6 is the second test value, 4 corresponds to the first touch sensor and 6 corresponds to the second touch sensor. Firstly, calculating the absolute value of the difference between the first test value and the second test value, namely the absolute value of the difference between 4 and 6 is 2; then, determining a first span value based on a ratio of the absolute value of the difference to the first test value, specifically, taking the absolute value of the difference as a dividend, taking the first test value as a divisor, and calculating to obtain a quotient as a first span value, that is, 2/4 obtains 0.5, where the first span value is 0.5; the absolute value of the difference may also be used as a dividend, the first test value is used as a divisor, and the percentage of quotient conversion obtained by calculation is used as a first span value, that is, 2/4 × 100% obtains 50%, and the first span value is 50% at this time, which is not specifically limited in this embodiment of the disclosure. Of course, 6 may be used as the first test value, 4 may be used as the second test value, and then 6 corresponds to the first touch sensor and 4 corresponds to the second touch sensor.
In yet another embodiment, the second determining module 1003 includes:
a first detection unit for detecting whether the first span value is greater than a predetermined span value;
and the third determining unit is used for determining that the first touch sensor and the second touch sensor are abnormal under the condition that the first span value is greater than the preset span value.
Considering that the difference degree between two adjacent touch sensors is large, the user may have the situations of touch dislocation, touch insensibility and the like in the process of using the touch screen, and therefore, the difference degree between two adjacent touch sensors needs to be limited within a certain range to avoid the situations of touch dislocation, touch insensibility and the like of the touch screen. Specifically, the predetermined span value is determined based on the historical test data, and the two adjacent touch sensors do not cause the situations of touch dislocation, touch insensibility and the like of the touch screen when the difference degree corresponding to the predetermined span value exists.
Further, after the first span value is determined, the first span value is compared with a preset span value, and if the first span value is larger than the preset span value, it is determined that the first touch sensor and the second touch sensor are abnormal.
In yet another embodiment, the first determining module 1002 further comprises:
a fourth determination unit for determining a second span value based on a ratio of the absolute value of the difference to the second test value.
After the first span value is obtained through calculation, a second span value is further determined based on a ratio of an absolute value of a difference value between the first test value and the second test value to the second test value, the absolute value of the difference value can be used as a dividend, the second test value is used as a divisor, and a quotient is obtained through calculation and is used as the second span value; the absolute value of the difference value can be used as a dividend, the second test value can be used as a divisor, the percentage of quotient conversion is calculated to be used as a second span value, and the like, as long as the type of the quotient conversion is consistent with that of the first span value.
For example, taking 6 as a first test value and 4 as a second test value, the first span value calculated is [ (| 6-4 |/6) × 100% ] -33.33%, and the second span value calculated is [ (| 4-6 |/4) × 100% ] -50%. Of course, if 4 is taken as the first test value and 6 as the second test value, the first span value calculated is [ (| 4-6 |/4) × 100% ] -50%, and the second span value calculated is [ (| 6-4|/6 × 100% ] -33.33%.
In yet another embodiment, the second determining module 1003 further includes:
the second detection unit is used for detecting whether the first span value is larger than the preset span value or not and detecting whether the second span value is larger than the preset span value or not.
After the first span value and the second span value are determined, comparing the first span value with a preset span value, and judging whether the first span value is greater than the preset span value; and comparing the second span value with the preset span value to judge whether the second span value is greater than the preset span value.
And the fifth determining unit is used for determining that the first touch sensor and the second touch sensor are abnormal under the condition that the first span value and the second span value are both larger than the preset span value.
Here, when both the first span value and the second span value are greater than the predetermined span value, it is determined that both the first touch sensor and the second touch sensor are abnormal, which is higher in accuracy than when the first span value is greater than the predetermined span value, it is determined that both the first touch sensor and the second touch sensor are abnormal.
Of course, when the abnormal conditions of the first touch sensor and the second touch sensor are actually determined, the abnormal conditions can be determined according to the above-mentioned manner, that is, when the first span value is greater than the predetermined span value, it is determined that the first touch sensor and the second touch sensor are abnormal; or determining that the first touch sensor and the second touch sensor are abnormal under the condition that the first span value and the second span value are both larger than the preset span value. Here, in consideration of the fact that only one of the first span value and the second span value is greater than the predetermined span value, it may be determined that the first touch sensor is normal and the second touch sensor is abnormal when the first span value is greater than the predetermined span value and the second span value is less than the predetermined span value; and under the condition that the first span value is smaller than the preset span value and the second span value is larger than the preset span value, determining that the first touch sensor is abnormal and the second touch sensor is normal. Thus, the accuracy of detection can be improved.
In a specific implementation, a plurality of touch sensors may be simultaneously detected, for example, a first test value of a first touch sensor and a second test value of a plurality of second touch sensors are obtained, where each second touch sensor is adjacent to the first touch sensor, such as a cross shape, and further such as a return shape, etc.; as long as it is satisfied that the first touch sensor is adjacent to the second touch sensor.
In yet another embodiment, the detection apparatus further comprises:
the marking module 1004 is configured to mark the first touch sensor and the second touch sensor in the abnormal state, and display the marked first touch sensor and/or second touch sensor.
After all the touch sensors in the whole touch screen to be detected are detected, determining the abnormal condition of the touch screen based on the number, the positions and the like of the abnormal touch sensors; for example, when the number of the abnormal touch sensors is larger than a preset threshold, it is determined that the touch screen is abnormal; determining that the touch screen is abnormal and the like under the condition that the position of the abnormal touch sensor is within a preset range; the embodiment of the present disclosure is not particularly limited to this.
Further, after determining the abnormal conditions of all the touch sensors in the touch screen to be detected, the first touch sensor and the second touch sensor in the abnormal state may be marked. For example, when the second determining module 1003 determines that the touch sensors corresponding to the test values 4 and 6 are both abnormal, the areas corresponding to 4 and 6 may be filled with colors to be distinguished from other areas, so that when the marked first touch sensor and/or second touch sensor are displayed, an observer can easily distinguish a normal touch sensor from an abnormal touch sensor.
It should be noted that the color filled in the region corresponding to 4 and the color filled in the region corresponding to 6 may be the same or different; of course, other methods may be used for marking, for example, when the touch sensor corresponding to 6 is determined to be abnormal, marking "r" in the area corresponding to 6 is enough as long as the normal touch sensor can be distinguished from the abnormal touch sensor, and this is not particularly limited in the embodiment of the present disclosure.
The method and the device can effectively detect whether the adjacent touch sensors have large difference, avoid the condition that the touch screen is abnormal (for example, touch dislocation/touch cannot be sensed) due to the large difference between the adjacent touch sensors, and further improve the accuracy of detection of the touch sensors.
