and A3, determining whether the touch function of the display screen to be tested is normal or not according to the test touch data set and the real touch data set.
In this embodiment of the present application, the display screen to be tested may acquire a test touch data set for the display screen to be tested, where the test touch data set may include a plurality of touch data, and may also acquire a real touch data set for the display screen to be tested, where the real touch data set may also include a plurality of touch data. Furthermore, whether the touch function of the display screen to be tested is normal or not can be determined according to the test touch data set and the real touch data set, namely, the deviation between the test touch data set and the real touch data set is determined, and whether the touch function is normal or not is detected through the deviation between the test touch data set and the real touch data set, so that the touch function test can be realized.

And further, when the performance evaluation value is larger than a preset threshold value, determining that the touch function is normal, otherwise, when the performance evaluation value is smaller than or equal to the preset threshold value, determining that the touch function is abnormal, further, performing performance evaluation through the touch function to obtain the performance evaluation value, and quantifying the quality of the touch function through the performance evaluation value, thereby realizing accurate test on the touch function.

and B4, executing the step A31 when the absolute value of the difference value between the total number of the first touch points and the total number of the second touch points is smaller than or equal to the set value.
Wherein, the set value can be preset or default. In a specific implementation, the total number of first touch points contained in the test touch data set and the total number of second touch points contained in the real touch data set can be determined, when the absolute value of the difference between the total number of first touch points and the total number of second touch points is larger than a set value, the difference between the total number of first touch points and the total number of second touch points is larger, the touch function abnormality is determined, otherwise, when the absolute value of the difference between the total number of first touch points and the total number of second touch points is smaller than or equal to the set value, the step A31 is executed, so that the abnormality detection can be primarily performed on the touch function through the number of touch points, and the detection efficiency is improved.
Optionally, step a33, determining the deviation degree of each of the P touch points according to the P test touch data and the P real touch data to obtain P deviation degrees, may include the following steps:
a331, acquiring a first touch coordinate and a first touch force of test touch data i, wherein the test touch data i is test touch data of a touch point i, and the touch point i is any one of the P touch points;

a334, determining a second reference deviation degree according to the first touch force and the second touch force;
and A335, carrying out weighted operation according to the first reference deviation degree and the second reference deviation degree to obtain the deviation degree of the touch point i.
In a specific implementation, taking test touch data i as an example, the test touch data i is test touch data of a touch point i, the touch point i is any one of P touch points, then a first touch coordinate and a first touch force of the test touch data i can be obtained, then a second touch coordinate and a second touch force of real touch data i corresponding to the test touch data i are obtained, and a first reference deviation degree can be determined according to the first touch coordinate and the second touch coordinate, for example, a distance between the two touch coordinates can be determined, the larger the distance is, the larger the deviation degree is, and the smaller the distance is, the smaller the deviation degree is. Further, the second reference deviation degree may also be determined according to the first touch force and the second touch force, for example, a difference value between the two touch forces may be determined, where the larger the difference value is, the larger the deviation degree is, and the smaller the difference value is, and the smaller the deviation degree is. Finally, a weighted operation may be performed according to the first reference deviation degree and the second reference deviation degree, so as to obtain a deviation degree of the touch point i, for example, the first reference deviation degree may correspond to a first weight, and the second reference deviation degree may correspond to a second weight, which is specifically as follows:
The deviation of the touch point i=the first reference deviation, the first weight+the second reference deviation, the second weight
The range of the first weight and the second weight is 0-1, and the sum of the first weight and the second weight may be equal to 1, for example, the first weight=0.6, and the second weight=0.4.
Therefore, the quality of the touch function can be quantized through the touch coordinate difference and the touch force difference, and accurate detection of the touch function can be realized. Of course, the first weight and the second weight may also be in the form of weight pairs, and the selection of the weight pairs may be related to attribute information of the display screen, or may also be related to test content.

a341, determining a target deviation mean value and a target standard deviation of the P deviations;
a342, determining a reference performance evaluation value corresponding to the target deviation average value according to a mapping relation between the preset deviation and the performance evaluation value;
a343, determining a target optimization coefficient corresponding to the target standard deviation according to a mapping relation between a preset standard deviation and the optimization coefficient;
And A344, optimizing the reference performance evaluation value according to the target optimization coefficient to obtain the performance evaluation value of the touch function of the display screen to be tested.
The mapping relation between the preset deviation degree and the performance evaluation value and the mapping relation between the preset standard deviation and the optimization coefficient can be stored in the test equipment in advance. The standard deviation reflects the fluctuation condition of the performance, and further, the performance evaluation value can be optimized through the standard deviation, the smaller the standard deviation is, the smaller the optimization coefficient is, the larger the standard deviation is, the larger the optimization coefficient is, and the value range of the optimization coefficient can be 0-0.1.
In specific implementation, a target deviation mean value and a target standard deviation of the P deviations can be determined, then a reference performance evaluation value corresponding to the target deviation mean value is determined according to a mapping relation between a preset deviation and the performance evaluation value, then a target optimization coefficient corresponding to the target standard deviation is determined according to a mapping relation between the preset standard deviation and the optimization coefficient, and further the reference performance evaluation value can be optimized according to the target optimization coefficient to obtain the performance evaluation value of the touch function of the display screen to be tested, and the specific steps are as follows:
Performance evaluation value= (1-target optimization coefficient) reference performance evaluation value
Furthermore, the influence of a single touch point can be reduced by the average deviation, and in addition, the fluctuation influence among different touch points is optimized by the standard deviation, so that the accurate performance evaluation of the whole display screen is facilitated.

c1, acquiring display content to be tested and reference display effect parameters;
c2, sending the display content to be tested to the display screen to be tested, and indicating the display screen to be tested to display so as to obtain target display effect parameters;
c3, receiving the target display effect parameters sent by the display screen to be tested;
and C4, detecting whether the display screen to be tested displays normally or not according to the reference display effect parameter and the target display effect parameter.

Optionally, the step C4 of detecting whether the display screen to be tested displays normally according to the reference display effect parameter and the target display effect parameter may include the following steps:
c41, determining first average brightness and first saturation according to the reference display effect parameters;
c42, determining second average brightness and second saturation according to the target display effect parameters;
c43, determining an absolute value of a difference value between the first average brightness and the second average brightness to obtain a reference absolute value;
c44, determining a target gain parameter according to the first saturation and the second saturation;
c45, determining a target adjustment factor corresponding to the target gain parameter;
c46, adjusting the reference absolute value according to the target adjusting factor to obtain a target absolute value;
and C47, detecting whether the display screen to be tested displays normally or not according to the target absolute value.
In a specific implementation, the first average brightness and the first saturation may be determined according to a reference display effect parameter, where the reference display effect parameter may include a display effect parameter of each pixel point of the display screen to be tested, and similarly, the second average brightness and the second saturation may be determined according to a target display effect parameter, and then an absolute value of a difference between the first average brightness and the second average brightness may be determined to obtain a reference absolute value.
Further, the target gain parameter may be determined according to the first saturation and the second saturation, which is specifically as follows: the target gain parameter= (second saturation-first saturation)/first saturation may determine a target adjustment factor corresponding to the target gain parameter according to a mapping relationship between a preset adjustment factor and the gain parameter, in this embodiment, the value range of the adjustment factor may be-0.2, and then the reference absolute value is adjusted according to the target adjustment factor to obtain a target absolute value, that is, the target absolute value= (1+target adjustment factor) ×the reference absolute value, and finally, whether the display screen to be tested is normal or not may be detected according to the target absolute value, where the smaller the absolute value is, the better the display effect of the display screen is, and conversely, the larger the absolute value is, the worse the display effect of the display screen is, so that the display function of the display screen may be detected.
