The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless expressly specified otherwise.

In order to explain the technical means described in the present application, the following description will be given by way of specific embodiments.

Referring to fig. 1, which is a flowchart illustrating a first implementation procedure of a detection method for providing an electronic metering device according to an embodiment of the present application, for convenience of description, only a portion related to the embodiment of the present application is shown.

First, one or more embodiments of the present specification provide a method for detecting an electronic metering device, where the electronic metering device includes a capacitive touch screen, the method includes:

s101, obtaining dead points of the capacitive touch screen, wherein the dead points refer to capacitive points in the capacitive touch screen, the capacitance values of which do not meet standard conditions, the capacitance values are calculated through a capacitance value calculation formula, and the capacitance value calculation formula isWherein, in the step (A),in order to have a dielectric constant in a vacuum,is the dielectric constant of the edge dielectric layer; s is the area of the part opposite to the electrode plate; d is the thickness of the insulating medium layer, and when the C does not meet the standard condition, the current capacitance point is determined to be a dead point.

In this embodiment, the electronic metering device first obtains a capacitance value of a capacitance point in the capacitive touch screen, and then determines whether the capacitance value of the capacitance point meets a preset standard condition, and if not, determines that the capacitive touch screen is a defective pixel. It should be noted that the capacitive touch screen is formed by orderly arranging a plurality of capacitors, a position where each capacitor is located is called a capacitor point, and a capacitance value is obtained by measuring the capacitor point. The capacitance value can be obtained by measuring the capacitance value of each capacitance point through a professional measuring instrument and then directly receiving the value fed back by the measuring instrument; the analog signal conducted by the capacitance point can also be directly acquired and then converted into a corresponding numerical value through analog-to-digital conversion, wherein the numerical value directly corresponds to the analog signal, the concept of the capacitance value is not necessarily the same as the concept of the capacitance value accepted on the market, and the capacitance value is not necessarily applicable to the capacitance international unit farad and the like.

In some possible embodiments, the capacitive touch screen includes a driving end and a receiving end, the driving end and the receiving end may be disposed at any position of the capacitive touch screen, the driving end and the receiving end may not be located at opposite sides, the driving end includes a driving line, the receiving end includes a receiving line, and each intersection point of the driving line and the receiving line is a capacitive point. It is assumed that the number of driving lines at the driving end is N, and the number of receiving lines at the receiving end is M, so that the number of formed capacitance points is N × M. All capacitance points in the horizontal direction or the vertical direction in the same direction are called capacitance points on a horizontal line or a vertical line, wherein M capacitance points are arranged on one driving line, and N capacitance points are arranged on one receiving line. The current flows through the capacitance point through the driving line to the receiving line and finally to the receiving end. And finally obtaining the capacitance value of each capacitance point by acquiring the signal of the receiving end.

In some other possible embodiments, the standard condition is that the capacitance value is greater than a predetermined maximum capacitance threshold value and/or less than the predetermined minimum capacitance threshold value. In other words, the dead pixel refers to a capacitive point that cannot work normally or the working sensitivity and accuracy cannot meet the requirements in the capacitive touch screen. The formed dead pixel can be a low-capacitance dead pixel generated by too low capacitance value of the capacitance point, so that the capacitance point cannot work normally; the high capacitance defect generated by the over-high capacitance of the capacitance point may cause the sensitivity of the capacitance point to be abnormal, and the touch of the user may not be accurately reflected or the color change of the screen may not be accurately responded. In addition, the detected capacitance point is the capacitance point currently being detected.

Therefore, the preset condition that the capacitance value needs to satisfy may be only when the capacitance value is lower than a preset threshold value; it is also possible that only when the capacitance value is higher than a preset threshold value; it is also possible to detect the case of too low or too high a capacitance value at the same time. Meanwhile, as can be seen from the previous step, the expression form of the capacitance value may be international farad unit expression or the like, or may be a digital signal reflecting only an analog signal of the capacitance point. The value of the predetermined condition also corresponds to the representation of the capacitance value.

In a specific application scenario, it is checked whether the capacitance value is smaller than an allowed lowest threshold (this lowest threshold is an empirical value, taken as 50% of the average of all signals from a plurality of sample capacitive screens). If the capacitance signal is below the threshold, the point is determined to be a bad point. At the same time, it is checked whether the capacitance value is greater than the highest allowed threshold (this highest threshold is an empirical value 250, while the theoretical value of the signal value ranges from 0 to 255). If the capacitance value signal is higher than the threshold value, the point is determined to be a dead point.

In some possibly implemented embodiments, the dead pixel includes a first dead pixel and a second dead pixel, and correspondingly, the dead pixel of the capacitive touch screen is obtained, where the dead pixel refers to a capacitive point in the capacitive touch screen whose capacitance value does not meet a standard condition, and specifically includes:

when the capacitance value is smaller than the lowest threshold value, determining that the detected capacitance point corresponding to the capacitance value is a first dead pixel;

and when the capacitance value is larger than the highest threshold value, determining that the detected capacitance point corresponding to the capacitance value is a second dead pixel.

S102: and when the dead points are used as detection starting points, and the capacitance points of which the number is continuously preset in the arrangement sequence of the capacitance points are all dead points, determining that the electronic metering device is an unqualified capacitive touch screen product.

In this embodiment, when the electronic metering device obtains a dead pixel of the capacitive touch screen, it determines that the dead pixel is a base point, that is, a detected starting point, and determines whether a next capacitive point is a dead pixel according to the array sequence of the capacitive points, and if a preset number of the capacitive points are dead pixels, it determines that the capacitive touch screen is unqualified, and the electronic metering device is an unqualified product.

It should be noted that the arrangement sequence means that in the process of the capacitive touch screen component, the connection of each capacitor is arranged and connected according to the sequence of each line, a plurality of capacitor points are arranged on each driving line or each receiving line of the capacitive screen in sequence, each line is arranged in sequence from the capacitor point closest to the driving end or the receiving end, and the capacitor point farthest from the driving end or the receiving end on each line is the end capacitor point. Furthermore, it can be understood that, since each capacitance point is located on one driving line and one receiving line, and the detected capacitance point is taken as a starting point according to the arrangement sequence, the capacitance points can actually extend in four directions, for example, on the driving line, the detection is performed in the direction away from the driving end along the communication sequence, or the detection is performed in the direction close to the driving end against the communication sequence, and the same is true on the receiving line.

Because the number of the capacitors in the capacitive touch screen is too many, the situation of a problematic capacitor in the capacitor is caused, and the situation of a single capacitor defective pixel is caused in many ways, so that if a defective pixel is caused, the problem that the whole capacitive touch screen has a non-negligible problem is not realistic, and meanwhile, the production efficiency caused by the detection mode is very low and the cost is very high. Furthermore, whether a plurality of continuous points are dead spots or not is detected through the step, and the capacitive screen with non-negligible problems such as broken lines, large-area dead spots and the like is further detected.

Referring to fig. 2, in some possible embodiments, when the number of the capacitor points that are continuously preset in the arrangement sequence of the capacitor points is all dead points with the dead point as a detection starting point, determining that the electronic metering device is an unqualified product of the capacitive touch screen specifically includes:

s201: when the detected capacitor points are first dead points or second dead points, judging whether the detected capacitor points are detected in the initial direction of the arrangement sequence by taking the detected capacitor points as a starting point according to the arrangement sequence of the capacitor points, and judging whether the preset number of the capacitor points are the first dead points or the second dead points;

s202: and if so, determining that the electronic metering device is an unqualified capacitive touch screen product of a dead pixel aggregation type.

When the dead pixel is detected, the dead pixel is used as a base point, dead pixel detection is performed in four directions, that is, four directions in which the driving line and the receiving line are located, whether a preset number of first dead pixels or second dead pixels exist is detected, if yes, it is determined that all the dead pixels exist in the area, that is, the capacitive touch screen is damaged in a large area, and the capacitive touch screen is determined to be a dead pixel aggregation type capacitive touch screen, and the electronic metering device is an unqualified product of the dead pixel aggregation type capacitive touch screen.

In some possibly implemented embodiments, when the capacitor points are all dead points in a preset number of consecutive capacitor points in the arrangement order of the capacitor points with the dead point as a detection starting point, determining that the electronic metering device is an unqualified product of the capacitive touch screen specifically includes:

when the detected capacitor points are first dead points, judging whether the detected capacitor points are detected in the initial direction of the arrangement sequence by taking the detected capacitor points as a starting point according to the arrangement sequence of the capacitor points, and judging whether the preset number of the capacitor points are the first dead points or not;

and if so, determining that the electronic metering device is an unqualified capacitive touch screen product of a broken line type.

When the dead pixel is detected, the dead pixel is used as a base point, the arrangement sequence of the capacitance points is detected, whether a continuous number of first dead pixels exist is detected, if yes, the arrangement sequence direction of the dead pixel is determined, the driving line or the receiving line is all dead pixels, namely the line is in a broken line state, the capacitance touch screen is determined to be a broken line type capacitance touch screen, and then the electronic metering device is determined to be an unqualified broken line type capacitance touch screen product.

In some other embodiments that may be implemented, when the number of the capacitor points that are continuously preset in the arrangement order of the capacitor points is not all dead points, taking the dead point as a detection starting point, counting the number of the dead points that are all dead points of the capacitor touch screen, and calculating a dead point rate of the capacitor touch screen according to the number of the dead points and the total number of the capacitor points;

and when the dead pixel rate is greater than a preset threshold value, determining that the electronic metering device is an unqualified capacitive touch screen product with excessive dead pixels.

When the electronic metering device detects the dead pixels, counting all the dead pixels in the capacitive touch screen, and calculating the dead pixel rate of the capacitive touch screen according to the ratio of the total number of the dead pixels to the total number of the capacitive points. And when the defective pixel rate is larger than a preset threshold value, determining that the capacitive touch screen is a capacitive touch screen with excessive defective pixels, and determining that the electronic metering device is an unqualified capacitive touch screen with excessive defective pixels.

In some possibly implemented embodiments, the obtaining a dead pixel of the capacitive touch screen, where the dead pixel is before a capacitance point of the capacitive touch screen whose capacitance value does not meet a standard condition, further includes:

acquiring an analog signal generated by the capacitance point;

converting the analog signal to a digital signal using analog to digital conversion;

and transmitting the digital signal through a universal serial bus channel, and analyzing the digital signal to generate the capacitance value.

In some other possibly implemented embodiments, the method further includes, after obtaining a dead pixel of the capacitive touch screen, where the dead pixel is a capacitive point in the capacitive touch screen whose capacitance value does not meet a standard condition, the method further includes:

and displaying the dead pixels in special colors through a preset display rule.

The judged passing capacitor point is the normal capacitor point, the passing capacitor point can be displayed by colors such as green and the like during display, the passing capacitor point is detected as a dead pixel and is displayed by colors such as red and the like, the special color is the color which is obviously different from the color used by the normal capacitor point, and the colors of the passing capacitor point and the dead pixel are convenient to distinguish.

Compared with the prior art, the implementation mode of the invention has the following beneficial effects: firstly, dead spots of the capacitive touch screen are obtained, wherein the dead spots refer to capacitive points in the capacitive touch screen, the capacitance values of which do not meet standard conditions, the capacitance values are calculated through a capacitance value calculation formula, and the capacitance value calculation formula isWherein, in the step (A),in order to have a dielectric constant in a vacuum,is the dielectric constant of the edge dielectric layer; s is the area of the part opposite to the electrode plate; d is the thickness of the insulating medium layer, when the C does not meet the standard condition, the current capacitance point is determined to be a dead point, and then when the dead point is taken as a detection starting point and all the capacitance points continuously preset in number in the arrangement sequence of the capacitance points are dead points, the electronic metering device is determined to be an unqualified capacitive touch screen product. And finding the defective point with the abnormal capacitance value by acquiring the capacitive touch screen, and continuously detecting other capacitive points arranged in the sequence by taking the detected first defective point as a base point to determine whether the electronic metering device is a qualified product. Whether the capacitive touch screen is damaged or not is detected manually, the detection efficiency is low, the error is high, and therefore the technical effects that the detection efficiency is improved, the metering precision of the electronic metering device is improved and the like can be achieved.
