The preset test image data may be test image data for the display screen to be tested, or at least include one piece of test image data for the display screen to be tested. The preset test image data may correspond to attribute information of the display screen to be tested.
In the specific implementation, after the communication connection is established between the testing device and the display screen to be tested, the preset testing image data can be sent to the display screen to be tested, and the display screen to be tested is instructed to display the preset testing image data to obtain the display effect data, wherein the display effect data can be various display effect data contained in the actual display effect image.
The display effect data may include display effect data of a plurality of pixels, and the display effect data of each pixel may include at least one of: pixel values, pixel coordinate locations, pixel colors, etc., without limitation.
Optionally, before the step 101, the following steps may be further included:
a1, acquiring a target attribute parameter of the display screen to be tested;
a2, determining a target test data identifier corresponding to the target attribute parameter according to a mapping relation between a preset attribute parameter and the test data identifier;
and A3, acquiring the preset test image data corresponding to the target test data identification from a test database.

The test database may store a plurality of types of test data in advance, and each test data may be for at least one type of display screen or for at least one developer's display screen.
Specifically, communication connection is established between the testing equipment and the display screen to be tested, then, a target attribute parameter of the display screen to be tested can be obtained in a communication interaction mode, then, a target testing data identifier corresponding to the target attribute parameter is determined according to a mapping relation between a preset attribute parameter and a testing data identifier, preset testing image data corresponding to the target testing data identifier is obtained from a testing database, then, the display screen can be tested by utilizing testing data corresponding to the display screen, and the efficiency and the accuracy of testing the display screen are improved.
302. And receiving the display effect data fed back by the display screen to be tested.
The display screen to be tested can send the display effect data to the testing equipment, and then the testing equipment can receive the display effect data fed back by the display screen to be tested.
303. And determining a test result of the display screen to be tested according to the display effect data.
The display effect data can represent the display effect of the display screen to be tested, and then the test result of the display screen to be tested can be determined through the display effect data, and the test result can include a test result of at least one dimension, for example, the test result can be normal for display of the display screen, and for example, the test result can be abnormal for display of the display screen, and for example, the test result can include a test result of at least one dimension of backlight, color accuracy, color cast with different brightness, display definition and image stability.
Optionally, in step 303, determining a test result of the display screen to be tested according to the display effect data may include the following steps:
a31, extracting preset type parameters according to the display effect data;
a32, acquiring a comparison threshold corresponding to the preset type parameter;
and A33, comparing the preset type parameter with the comparison threshold value to obtain a comparison result, and determining the test result of the display screen to be tested according to the comparison result.
The preset type parameter may be a parameter of a preset test dimension, and the preset test dimension may be at least one of: backlight, color shift, sharpness, image stability, etc., without limitation. Different testing dimensions can correspond to different comparison threshold values, the mapping relation between the preset testing dimensions and the comparison threshold values can be stored in the testing equipment in advance, then the comparison threshold values corresponding to preset type parameters can be determined based on the mapping relation, then the preset type parameters are compared with the comparison threshold values to obtain comparison results, and the testing results of the display screen to be tested are determined according to the comparison results, namely the different comparison results can correspond to different testing result information, so that the display function of the display screen can be tested by the multiple testing dimensions, and further, the accurate testing of the display screen is facilitated.
Optionally, when the preset type parameter is an image stability evaluation parameter, the step a31 of extracting the preset type parameter according to the display effect data may include the following steps:
a311, dividing the display effect data into a plurality of regions to obtain a plurality of groups of region data;
a312, determining a mean square error corresponding to each region data in the multiple groups of region data to obtain multiple mean square errors;
a313, determining a stability evaluation parameter corresponding to each mean square error in the plurality of mean square errors according to a preset mapping relation between the mean square errors and the stability evaluation parameters to obtain a plurality of reference stability evaluation parameters;
a314, determining an adjusting parameter corresponding to each of the plurality of regions according to a mapping relation between the size of a preset region and the adjusting parameter to obtain a plurality of adjusting parameters;
a315, calculating according to the reference stability evaluation parameters and the adjustment parameters to obtain a plurality of target stability evaluation parameters;
a316, determining the image stability evaluation parameters according to the target stability evaluation parameters.
In a specific implementation, the preset type parameter may be an image stability evaluation parameter, that is, a display function of the display screen is tested from an image stability dimension. In a specific implementation, the display effect data may be divided into a plurality of regions to obtain a plurality of sets of region data, and since the display effect data itself may be regarded as an image, which is equivalent to performing region division on the image, the size of each region may be the same or different.
Furthermore, the mean square error corresponding to each area data in the multiple sets of area data can be determined to obtain multiple mean square errors, that is, the mean square error between the pixel values of each area is calculated, and the mean square error can reflect the stability of the area image. Then, according to a preset mapping relationship between the mean square deviations and the stability evaluation parameters, the stability evaluation parameter corresponding to each mean square deviation in the plurality of mean square deviations can be determined to obtain a plurality of reference stability evaluation parameters, that is, the smaller the mean square deviation is, the better the stability is, and conversely, the larger the mean square deviation is, the worse the stability is.
Of course, the image stability is also related to the size of the region, i.e. the smaller the region, the greater the randomness of the calculated mean square error, whereas the larger the region, the influence of the local stability is unintentionally reduced, and therefore, different adjustment parameters may be set for different region sizes. And then, determining an adjusting parameter corresponding to each of the plurality of areas according to a mapping relation between the preset area size and the adjusting parameter to obtain a plurality of adjusting parameters, performing operation according to the plurality of reference stability evaluation parameters and the plurality of adjusting parameters to obtain a plurality of target stability evaluation parameters, namely determining a product between the corresponding reference stability evaluation parameter and the adjusting parameter, and taking the product as the target stability evaluation parameter.
Finally, the average value of the target stability evaluation parameters can be determined as the image stability evaluation parameters, so that on one hand, the influence of reducing local stability unintentionally brought by considering the whole image can be avoided, and on the other hand, the difference between the area size and the area is considered, so that the image stability evaluation is more objective and close to the actual display condition of the image, and the accuracy of the image stability evaluation is improved.
Optionally, when the comparison threshold is the first set value, the step a33 of comparing the preset type parameter with the comparison threshold to obtain a comparison result, and determining the test result of the display screen to be tested according to the comparison result may include the following steps:
a331, when the image stability evaluation parameter is larger than a first set value, determining that the image stability of the display screen to be tested meets the requirement of display stability;
and A332, when the image stability evaluation parameter is less than or equal to the first set value, determining that the image stability of the display screen to be tested does not meet the display stability requirement.
Wherein, the first setting value can be preset or default by the system. In the specific implementation, when the image stability evaluation parameter is greater than the first set value, it is determined that the image stability of the display screen to be tested meets the display stability requirement, and when the image stability evaluation parameter is less than or equal to the first set value, it is determined that the image stability of the display screen to be tested does not meet the display stability requirement.
Optionally, the method may further include the following steps:
b1, detecting whether a mean square error larger than a second set value exists in the plurality of mean square errors;
b2, when the mean square error larger than the second set value exists in the plurality of mean square errors, determining that the image stability of the display screen to be tested does not meet the display stability requirement;
and B3, when the mean square error larger than the second set value does not exist in the plurality of mean square errors, executing the step of determining the stability evaluation parameter corresponding to each mean square error in the plurality of mean square errors according to a preset mapping relation between the mean square error and the stability evaluation parameter to obtain a plurality of reference stability evaluation parameters.
The second setting value can be set by a user or defaulted by a system, if the mean square error is larger than the second setting value, the local image stability is very poor, and the image stability of the display screen to be tested is directly determined not to meet the display stability requirement.
In the specific implementation, whether the mean square error larger than the second set value exists in the plurality of mean square errors or not can be detected, when the mean square error larger than the second set value exists in the plurality of mean square errors, the fact that the image stability of the display screen to be tested does not meet the display stability requirement is directly determined, otherwise, when the mean square error larger than the second set value does not exist in the plurality of mean square errors, the step A313 is executed, and therefore, the method is equivalent to firstly achieving preliminary image stability detection and then performing depth image stability detection, and further improving the image stability detection efficiency.
Optionally, in step 303, determining a test result of the display screen to be tested according to the display effect data may include the following steps:
b31, determining a first image quality evaluation value of the preset test image data;
b32, determining a second image quality evaluation value of the display effect data;
b33, determining an absolute value of a difference between the first image quality evaluation value and the second image quality evaluation value;
b34, when the absolute value is smaller than a third set value, determining that the display of the display screen to be tested is normal;
and B35, when the absolute value is larger than or equal to the third set value, determining that the display screen to be tested is abnormal.
In a specific implementation, the third setting value may be preset or default to the system. The image quality evaluation of the preset test image data can be performed by using at least one image quality evaluation index to obtain a first image quality evaluation value, and the image quality evaluation index can include at least one of the following: information entropy, signal-to-noise ratio, sharpness, edge preservation, contrast, saturation, etc., without limitation. Similarly, a second image quality evaluation value of the display effect data can be determined, an absolute value of a difference value between the first image quality evaluation value and the second image quality evaluation value is determined, when the absolute value is smaller than a third set value, it is determined that the display of the display screen to be tested is normal, otherwise, when the absolute value is larger than or equal to the third set value, it is determined that the display of the display screen to be tested is abnormal, and thus, whether the display function of the display screen is normal can be tested by presetting the difference between the test image data and the display effect data, which is beneficial to improving the test efficiency of the display function.
Optionally, when the preset test image data includes a plurality of test image data, the display effect data includes a plurality of groups of display effect data, in step 303, determining the test result of the display screen to be tested according to the display effect data, which may include the following steps:
c31, selecting the best group of target display effect data in the multiple groups of display effect data;
and C32, determining a test result of the display screen to be tested according to the target display effect data.
When the preset test image data comprise a plurality of test image data, each test image data can be specific to one display screen or one manufacturer, and then the plurality of test image data can be sent to the display screen to be tested for testing, only the test image data of the display screen is completely matched, the best display effect can be obtained, and further, based on the principle, the best target display effect data in a plurality of groups of display effect data can be selected, the test result of the display screen to be tested is determined through the target display effect data, so that the test is performed on the display screens of different types or different suppliers, and the test efficiency of the display screen is improved.

For example, as shown in fig. 4, in the embodiment of the present application, the LCD display screen may be tested in the connection manner as shown in the figure.
For example, as shown in fig. 5, for an application scenario of the RGB888 video mode, if the corresponding data transmission format is: and the video mode can test the LCD display screen in a connection mode as shown in the figure.
For another example, as shown in fig. 6, for an application scenario of generating an RGB888 command mode (command mode), the LCD display screen may be tested in the connection manner as shown in the figure.
