Detailed Description

The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.

An embodiment of the invention provides a detection method and device for a touch screen panel and a storage medium, and the detection method and device can avoid the problem that a good touch screen panel is judged to be a defective product, reduce the production cost and improve the production efficiency.

The method for detecting the touch screen panel of the present embodiment is based on the determination of whether the capacitance value of each capacitor on the touch screen panel meets the requirement. The capacitance detection module 10 may detect capacitance values, and then perform screening and analysis on data of the detected capacitance values, thereby forming the method.

Fig. 1 and 2 are flowcharts of a method for detecting a touch screen panel according to two embodiments of the present application, respectively, wherein fig. 2 is a more specific embodiment of the overall flowchart. Although the present application provides method operational steps as described in the following embodiments or flowcharts, the method is not limited to the order of execution provided in the embodiments of the present application in which the steps are logically not necessarily causal, based on conventional or non-inventive labor.

The detection method of the touch screen panel comprises the following steps:

step S1: acquiring capacitance matrix data of the touch screen panel;

specifically, the steps include:

acquiring a capacitance acquisition data set, wherein the capacitance acquisition data set is data of a plurality of detected capacitance values;

acquiring the number of rows and the number of columns of the capacitor of the touch screen panel, wherein the number of rows and the number of columns correspond to the actual arrangement on the panel;

and adjusting the capacitor acquisition data set to be the capacitor matrix data according to the number of the rows and the number of the columns, so that the capacitor acquisition data set is changed into matrix data of one row and one column, and the matrix data can be shown in fig. 6.

Step S2:

the first predetermined range may be a matrix having a size corresponding to the capacitance matrix data, for example, a matrix of 10 × 13, and the values of the 10 × 13 matrix data of the capacitance matrix data are compared with the values of a matrix of 10 × 13 first predetermined range. The first predetermined range may also be all one value, for example, all values in the capacitance matrix data are compared with the same value.

For example, a 10 × 13 matrix is determined, the first preset range is a range that is up to and down 20% of each value of the 10 × 13 matrix, for example, a certain value is 100, the floating range is within 80-120, and the floating range is satisfactory, each value in the capacitance matrix data is compared with the range that is up to 20% of each reference value, and if the value is within the range, the requirement is satisfied, and if the value is not within the range, the requirement is not satisfied.

Step S3:

when each capacitance value in the capacitance matrix data is not all within the first preset range, step S3 may be performed as follows:

and if not, judging the touch screen panel as a defective product.

Specifically, the abnormal capacitance includes an upper limit abnormal capacitance exceeding an upper limit of the first preset range, and the preset number condition includes an upper limit number condition;

the upper limit quantity condition comprises an upper limit row continuous value, an upper limit row discontinuous value, an upper limit column continuous value and an upper limit column discontinuous value;

step S3 includes:

step S311:

Step S312:

and if not, judging the touch screen panel as a defective product.

Further, the abnormal capacitance includes a lower limit abnormal capacitance lower than a lower limit of the first preset range, and the preset number condition includes a lower limit number condition;

the lower limit quantity condition comprises a lower limit row continuous value, a lower limit row discontinuous value, a lower limit column continuous value and a lower limit column discontinuous value;

step S3 further includes:

step S321:

Step S322:

and if not, judging the touch screen panel as a defective product.

The above step S3 will be described more specifically with reference to fig. 3, 4, and 5 as an example.

In the above example, the row-limited continuous value is 2, the upper row discontinuous value is 2, the upper column continuous value is 5, and the upper column discontinuous value is 5, OK in fig. 3, 4, and 5 is a normal capacitance whose capacitance value is within the first preset range, and NG is an upper abnormal capacitance which all exceeds the upper limit of the first preset range:

in fig. 3, the row continuous value is 1, the column continuous value is 4, there is no abnormal capacitance of row discontinuity and column discontinuity, and the upper limit row continuous value is 2 and the upper limit column continuous value is 5, which are all within the requirement, so the screen meets the requirement in the determination of step S3;

in fig. 4, the row continuous value is 2, the column continuous value is 2, there is no abnormal capacitance of row discontinuity and column discontinuity, and the upper limit row continuous value is 2, and the upper limit column continuous value is 5, so the row continuous value is not less than the upper limit row continuous value, so the screen is directly judged as a defective product in step S3;

in fig. 5, the row continuous value is 2, the column continuous value is 4, there is no abnormal capacitance of row discontinuity and column discontinuity, the upper limit row continuous value is 2, the upper limit column continuous value is 5, and the row continuous value is not less than the upper limit row continuous value, so the screen is directly determined as a defective product in step S3.

In addition, the following explanation is given by taking the case where the upper row-limited continuous value is 3, the upper row-limited discontinuous value is 3, the upper column-limited continuous value is 3, and the upper column-limited discontinuous value is 3:

in fig. 3, the row continuous value is 1, the column continuous value is 4, there is no abnormal capacitance of row discontinuity and column discontinuity, and the upper limit row continuous value is 3, the upper limit column continuous value is 3, and the row continuous value is greater than the upper limit row continuous value, which is not within the requirement. Therefore, the screen is directly judged as a defective product in step S3;

in fig. 4, the row continuous value is 2, the column continuous value is 2, there is no abnormal capacitance of row discontinuity and column discontinuity, and the upper limit row continuous value is 3 and the upper limit column continuous value is 3, both of them are within the requirement, so the screen meets the requirement in the determination of step S3;

in fig. 5, the row continuous value is 2, the column continuous value is 4, there is no abnormal capacitance of row discontinuity and column discontinuity, the upper limit row continuous value is 3, the upper limit column continuous value is 3, and the column continuous value is not less than the upper limit column continuous value, so the screen is directly determined as a defective product in step S3.

Similarly, when NG in fig. 3, 4, and 5 is an upper limit abnormal capacitance that partially exceeds the upper limit of the first preset range, a lower limit abnormal capacitance that partially exceeds the lower limit of the first preset range, or a lower limit abnormal capacitance that is less than the lower limit of the first preset range, the determination may be performed by referring to the above method.

Through the judgment, a single or a plurality of rectangles composed of abnormal capacitors in the screen are found, some abnormal capacitors are, for example, the position of a camera, the area of a light sensor, or some specific areas, or areas capable of being repaired, and the existence of the rectangular areas does not mean that the screen is directly a defective product, so that the continuous values of the upper limit row, the upper limit column and the upper limit column are adjusted according to requirements, and/or different parameters of the continuous values of the lower limit row, the lower limit column and the lower limit column are adjusted according to requirements, the requirements of screening the sizes and the quantities of different rectangles can be met, and when the sizes and the quantities exceed the requirements of the rectangles, the defective product is judged.

Step S4:

in step S2, when each capacitance value in the capacitance matrix data is all within a first preset range, step S4 may be performed:

performing a blending calculation determination, the blending calculation determination comprising the steps of:

calculating the difference value of capacitance values of two adjacent columns in the capacitance matrix data to generate column difference value matrix data, calculating the sum of the difference values of each row in the column difference value matrix data to generate row difference matrix data;

and judging whether the touch screen panel is good or not according to the row difference matrix data, the column difference matrix data, the difference matrix data and/or the column difference matrix data, the row difference matrix data and the difference matrix data.

Specifically, taking the tables in fig. 6 to 10 as an example, the step S4 is described more specifically:

FIG. 6 is a data table of capacitance matrix data listing the magnitude of all capacitance values of the capacitance matrix data, FIG. 6 is a 10 × 13 matrix, in accordance with one embodiment of the present invention;

FIG. 7 is a table of row difference matrix data according to an embodiment of the present invention, wherein two adjacent rows in FIG. 6 are subtracted to obtain the absolute value of the row difference matrix data to obtain FIG. 7, and FIG. 7 is a 9 × 13 matrix;

FIG. 8 is a table of column difference matrix data according to an embodiment of the present invention, wherein two adjacent columns in FIG. 6 are subtracted to obtain the absolute value of the subtracted column to obtain FIG. 8, and FIG. 8 is a 10 × 12 matrix;

FIG. 9 is a table of column sum difference matrix data for one embodiment of the present invention, summing all of the columns of FIG. 7 to obtain FIG. 9, FIG. 9 being a 9 x 1 matrix;

fig. 10 is a data table of row and difference matrix data for one embodiment of the invention, where fig. 10 is a 1 x 12 matrix obtained by summing all the rows in fig. 8.

Further, step S4 further includes the steps of:

comparing whether all of the data in the column difference matrix data are within a preset column difference matrix range, and/or,

if yes, judging the touch screen panel to be a good product;

and if not, judging the touch screen panel as a defective product.

The range of the preset row difference matrix, the range of the preset column difference matrix, and the range of the preset row difference matrix may be a matrix with corresponding sizes, and the values of each position in the matrix are compared in a one-to-one correspondence manner, for example, 9 × 13 matrix data of the row difference matrix is compared with a value of a 9 × 13 preset row difference matrix. The predetermined row difference matrix range, the predetermined column and difference matrix range, the predetermined row and difference matrix range may all be a single value, for example, all values in the row difference matrix data may be compared to the same value.

The comparison can be only compared with any one or all of the comparisons, and the effect is better when all the comparisons are carried out, and the comparison significance lies in that:

in the test, a problem exists that the capacitance value of a certain measured point is close to the upper limit of a normal value, and the capacitance values of other adjacent measured points are close to the lower limit of the normal value, in the actual production, the phenomenon generally occurs in a whole row or a whole column, so the situation can be passed through by using the conventional detection method, but because the difference value of two adjacent capacitance values is overlarge, the screen is unqualified actually, namely, in the existing judgment, the problem of judgment missing exists, and the defective product is changed into a good product.

Therefore, by comparing the row difference matrix data, the column difference matrix data, the row difference matrix data and the column and difference matrix data, a relationship can be established between the capacitances of the adjacent rows, the capacitances of the adjacent columns, the capacitances of all rows and all columns, for example, in fig. 9, if all values in the column and difference matrix data are required to be below 2000, the touch screen panel can be judged as a defective product.

The judgment in step S4 takes into consideration the uniformity of the difference between the capacitance values of the adjacent points of the touch screen panel and the uniformity of the difference between the capacitance values of the entire touch screen panel, so that the problems of missing detection and missing judgment are avoided.

Step S5:

on the basis of step S3, when the number of the abnormal capacitors meets the preset number condition, step S5 is performed, and one embodiment of step S5 is as follows:

For example, in step S2, the first predetermined range is, for example, 20% of fluctuation, the reference value is 100, the capacitance value is satisfactory within 80 to 120, and the second predetermined range is, for example, 40% of fluctuation, the capacitance value is satisfactory within 60 to 140, which means that the requirement of the point capacitance value is relaxed on the basis of the quantitative determination that the requirement is satisfactory, and if the requirement is still not satisfied under the relaxed condition, the touch screen panel is determined to be a defective product.

The problem of the excessive inspection of a part of screens is avoided, and the premise that the first preset range is widened to the second preset range is that the number meets the requirement, so that the problems of missed inspection and defective product judgment as a good product are also avoided.

Further, the step of "comparing whether each capacitance value of the abnormal capacitances is within a second preset range" includes:

if all the capacitance values are within the second preset range, the hybrid calculation determination is performed, that is, the determination of step S4 is performed.

At this time, since the uniformity of the adjacent capacitors and the uniformity of the whole capacitor are not determined within the requirement of the second preset range, the good capacitor is further determined by screening in step S4.

In other examples of step S5, another implementation of step S5 is as follows:

the blend calculation determination is performed, that is, the determination of step S4 is directly performed.

If the capacitance values of a row and a column of some screens may be all 0, at this time, even if the second predetermined range is determined to be still not passed, but the capacitance values of the row and the column may be normal, for example, the capacitance values of the camera position and the light sensor position may be very small or even 0, so that the second predetermined range is not determined at this time, and the determination of step S4 is directly performed.

Compared with the prior art, the embodiment has the following beneficial effects:

by the method for detecting the touch screen panel, the probability of over-judgment can be reduced, and the good-quality touch screen panel is screened at least from two dimensions of the capacitance value and the abnormal capacitance, so that the problem that the good-quality touch screen panel is judged to be a poor-quality product is solved, the production cost is reduced, and the production efficiency is improved.
