Description

Technical Field

[0002] As a human-computer interface, touchscreen displays play a crucial role in modern smart devices. Their electrical performance directly impacts the user experience, requiring various electrical performance tests, including but not limited to testing core parameters such as wiring resistance, insulation resistance, capacitance, response time, linearity, sensitivity, and power consumption. Each core parameter must meet design standards, meaning it must be within a specified data range. After all core parameters are tested, all test data is integrated to assess the health of the touchscreen. While this testing method can fully assess the electrical performance of touchscreens, it suffers from the following issues: It cannot update the health of the touchscreen in real time based on the data already tested. Furthermore, while corresponding data ranges (design standards) are set for each parameter, the closer the core parameter test is to the optimal standard, the better the electrical performance. However, current testing methods only use whether each parameter is within the corresponding design standard as the decision logic. Therefore, a high-precision electrical performance testing method for touchscreens is urgently needed to address these issues. Summary of the Invention

Obviously, the drawings described below are merely embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on the provided drawings without any creative work.

[0040] Figure 1 This is a flow chart of an electrical performance testing method for high-precision testing of a touch display component provided in an embodiment of the present application. DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0042] In this application, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus comprising the element.

[0043] Example

[0044] From the above background technology, it can be seen that the touch display component, as a human-computer interaction interface, plays a vital role in modern smart devices. Its electrical performance data will directly affect the user experience. Therefore, it is necessary to test its various electrical performances, including but not limited to testing of core parameters such as wiring resistance, insulation resistance, capacitance characteristics, response time, linearity, sensitivity and power consumption. The test of each core parameter needs to meet the design standards, that is, it must be within the set data range.

[0045] In the prior art, a test method is provided for each core parameter. All core parameters are tested using the corresponding test method to obtain a plurality of test data, and then all the test data are analyzed and processed to evaluate the electrical performance of the touch display component. However, this method has the following problems: First, it is impossible to use the detected data to update the health status of the touch display component in real time; second, it is impossible to make a higher-precision distinction of the electrical performance of the touch display component.

[0046] Therefore, the present application provides a method for detecting electrical performance of a touch display component with high precision, such as Figure 1 Shown, including:

[0047] Obtain all parameters to be tested of the touch display component, and obtain the initial qualified range and optimal values ​​of all parameters to be tested;

[0048] Store all parameters to be tested and corresponding test methods into the preset data set;

[0049] Based on the preset data set, a corresponding test means for any parameter to be measured is obtained, the parameter to be measured is tested based on the test means to obtain a test value, and it is determined whether the test value is within a corresponding initial qualified interval. If not, an early warning is issued. If so, the initial qualified interval is divided into a plurality of equal data intervals, and the data interval corresponding to the optimal value is recorded as the optimal interval. The distance between the data interval where the test value is located and the optimal interval is calculated to obtain a calculation result;

[0050] Traversing the remaining data in the preset data set to obtain multiple calculation results;

[0051] Building an electrical performance model, and training the electrical performance model based on all test values ​​and all calculation results;

[0052] Based on the trained electrical performance model, the electrical performance of the touch display component to be tested is displayed and updated.

[0053] Among them, all the parameters to be measured of the touch display component include wiring resistance, insulation resistance, capacitance characteristics, response time, linearity, sensitivity and power consumption. It should be noted that the parameters to be measured for different types of touch display components can be adjusted according to actual conditions and are not specifically limited in this embodiment.

[0054] Among them, the initial qualified range and optimal values ​​of all parameters to be tested can be obtained through industry standards and relevant manuals.

[0055] Among them, all parameters to be tested and corresponding test methods are stored in a preset data set. For example, the wiring resistance test adopts the four-wire Kelvin test method, the insulation resistance test adopts the application of high voltage to detect the insulation between layers, the capacitance characteristic test adopts the dynamic capacitance change capture, and the response time test adopts high-speed signal excitation and acquisition. The corresponding test methods of the remaining test parameters can also adopt mature test methods in the industry, which will not be elaborated in detail in this embodiment.

[0056] Among them, based on the preset data set, the corresponding test means of any parameter to be measured is obtained, the parameter to be measured is tested using the test means, and a test value is obtained. It is judged whether the test value is in the corresponding initial qualified interval. If not, an early warning is issued. If so, the initial qualified interval is divided into several equal data intervals, and the data interval corresponding to the optimal value is recorded as the optimal interval. The distance between the data interval where the test value is located and the optimal interval is calculated, and the distance between the test value and the optimal value is replaced by the interval distance, which eliminates the difference caused by the dimension and can more intuitively obtain the distance between the test value and the optimal value.

[0057] Among them, the distance between the data interval where the test value is located and the optimal interval is calculated. For example, if the number of data intervals between the data interval where the test value is located and the optimal interval is 3, then 3 is the distance between the test value and the corresponding optimal value.

[0058] Among them, the electrical performance model is constructed and trained using all test values ​​and all calculation results, including:

[0059]

[0060] P is the electrical performance value of the touch display component, M is the number of test parameters, d i is the distance between the data interval where the test value of the test parameter is located and the corresponding optimal interval;

[0061] Whenever any test parameter is tested, the distance between the data interval where the test value of the test parameter is located and the corresponding optimal interval is input into the above formula, and the electrical performance value of the touch display component is displayed and updated;

[0062] The construction logic of the above formula is based on the principle that the closer the test value is to the optimal value, the better the electrical performance of the touch display component. When the distance between the test value and the optimal value is greater, the electrical performance of the touch display component is worse. In addition, a cumulative formula is designed, that is, each time a test is completed, it can be updated through the cumulative formula.

[0063] Among them, based on the electrical performance model, monitoring the electrical performance value of the touch display component to be tested includes:

[0064] When the electrical performance value of the touch display component to be tested is lower than the first threshold, a first method is adopted for processing;

[0065] When the electrical performance value of the touch display component to be tested is lower than the second threshold, the second method is adopted;

[0066] When the electrical performance value of the touch display component to be tested is lower than the third threshold, a third method is adopted;

[0067] Its first threshold is greater than the second threshold and greater than the third threshold. It should be noted that the electrical performance value of the touch display component to be tested is based on the electrical performance value after the core parameters have been tested. For example, after the wiring resistance and response time tests have been carried out, the linearity test is to be carried out. At this time, if the electrical performance value of the touch display component to be tested is already lower than the first threshold, it is necessary to determine whether the distance between the data interval where the linearity test value is located and the corresponding optimal interval exceeds the first preset value (such as 5), indicating that the electrical performance of the touch display component is in poor condition. If so, an early warning is required, otherwise, no action is taken; if the touch If the electrical performance value of the display component is lower than the second threshold, it means that the electrical performance of the touch display component is poor. It is necessary to determine whether the distance between the data interval of the linearity test value and the corresponding optimal interval exceeds the second preset value (such as 3). If so, an early warning is required. If not, no action is taken. If the electrical performance value of the touch display component to be tested is lower than the third threshold, it means that the electrical performance of the touch display component to be tested is close to the category of unqualified products. It is necessary to determine whether the data interval of the linearity test value belongs to the corresponding optimal interval. If so, no action is taken. If not, an early warning is required. It should be noted that the first preset value is greater than the second preset value.

[0068] In some embodiments, calculating the distance between the data interval where the test value is located and the optimal interval to obtain the calculation result includes:

[0069] Obtaining the position of the optimal interval and marking it as a reference position;

[0070] The number of intervals between the data interval where the test value is located and the reference position is obtained as N, and N is used as the distance between the data interval where the test value is located and the optimal interval.

[0071] In some embodiments, training the electrical performance model based on all test values ​​and all calculation results includes:

[0076] When the electrical performance value of the touch display component to be tested is lower than a first threshold, a first method is used for processing;

[0077] When the electrical performance value of the touch display component to be tested is lower than a second threshold, a second method is used for processing;

[0078] When the electrical performance value of the touch display component to be tested is lower than a third threshold, a third method is used for processing;

[0079] The first threshold is greater than the second threshold, and the second threshold is greater than the third threshold.
