Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a screen testing method, system, industrial computer and storage medium. Background Art

[0002] With the rapid development of media technology, a large amount of visual information has appeared in daily life, which provides more possibilities for people's communication. Users can achieve information exchange by using various types of electronic devices. Furthermore, it is necessary to perform display tests on various types of display screens to understand the screen display performance.

[0003] Currently, there is a way to test the performance parameters of the screen through measuring instruments, but it cannot be completely free from human intervention. Manual operation takes a lot of time and effort, and is prone to problems such as inaccurate control of measuring instruments, low data statistical efficiency, and errors in judgment. Summary of the invention

[0004] The present application provides a screen testing method, system, industrial computer and storage medium, which can reduce the manpower input in the screen testing process and improve the accuracy of screen testing while ensuring the efficiency of screen testing.

[0005] In a first aspect, a method for testing a screen is provided, comprising: detecting a test task, the test task comprising at least one test item; obtaining, according to the at least one test item, a test image corresponding to each test item and an optical parameter to be tested corresponding to each test item; sending the test image corresponding to each test item to the screen to be tested, so that the screen to be tested displays the test image; sending the optical parameter to be tested corresponding to each test item to a measuring instrument, so that the measuring instrument collects parameter values ​​of the optical parameter to be tested; obtaining the parameter values ​​of the optical parameter to be tested collected by the measuring instrument; generating a test result of the screen to be tested according to the parameter values ​​of the optical parameter to be tested, wherein the test result of the screen to be tested is used to indicate the display performance of the screen to be tested.

[0006] In the above method, a test task is acquired based on the test item selected by the user, a test image corresponding to the test item is sent to the screen to be tested, and the optical parameter to be tested corresponding to the test item is sent to the measuring instrument, so that when the screen to be tested displays the test image corresponding to the test item, the measuring instrument detects the screen to be tested that is currently displaying the test image, and acquires the parameter value of the optical parameter to be tested corresponding to the test item; and a test result of the screen to be tested is generated based on the parameter value of the optical parameter to be tested acquired by the measuring instrument, indicating the display performance of the screen to be tested. In the method of the present application, on the one hand, since the test method of the present application does not require human intervention, it can send the test image corresponding to the test item to the screen to be tested based on the test item in the test task, and can send the optical parameter to be tested corresponding to the test item to the measuring instrument based on the test item in the test task, so as to realize automatic testing of the screen to be tested, reduce manpower input, and improve testing efficiency; on the other hand, in this case, when testing the screen to be tested, for each test item in at least one test item, the test image corresponding to each test item and the parameter value of the optical parameter to be tested can be obtained; through the test image corresponding to each test item and the parameter value of the optical parameter to be tested, targeted testing of the test item is realized, so that the test result of each test item obtained is more accurate; by improving the accuracy of each test item, the accuracy of the test result of the screen to be tested can be improved; while ensuring the efficiency of screen testing, the accuracy of screen testing is improved.

[0007] In combination with the first aspect, in some possible implementations, if the test images corresponding to each test item include at least two identical test images, and the at least two identical test images correspond to a target test item in at least one test item, the optical parameters to be measured corresponding to each test item are sent to the measuring instrument, including: simultaneously sending the optical parameters to be measured corresponding to the target test item to the measuring instrument, so that the measuring instrument simultaneously collects the parameter values ​​of the optical parameters to be measured corresponding to the target test items of the screen to be tested.

[0008] The target test items are at least two test items corresponding to the same test image.

[0009] In this embodiment, when at least two test images are the same among the test images corresponding to multiple test items, at least two test items (for example, target test items) can be tested simultaneously when the test image is displayed, that is, the measuring instrument can simultaneously collect the optical parameters to be tested corresponding to the at least two test items; compared with executing each test item separately, this solution can reduce the test time of the screen to be tested to a certain extent and improve the test efficiency.

[0010] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, at least one test item includes a first test item and a second test item, and the optical parameters to be measured corresponding to each test item are sent to the measuring instrument, including: sending the optical parameters to be measured corresponding to the first test item to the measuring instrument; after obtaining the parameter value of the optical parameter to be measured corresponding to the first test item collected by the measuring instrument, sending the optical parameter to be measured corresponding to the second test item to the measuring instrument.

[0011] In this embodiment, when executing multiple test items, another test item can be executed after one test item is completed, thereby avoiding mutual interference between the multiple test items and improving the accuracy of the test.

[0012] In one possible implementation, whether the current test item has been completed is determined by determining whether the parameter value of the optical parameter to be tested corresponding to the current test item is received; after completing the test of the current item, the optical parameter to be tested corresponding to the next test item is sent to the measuring instrument; and a test image corresponding to the next test item is sent to the screen to be tested, so that the measuring instrument obtains the parameter value of the optical parameter to be tested corresponding to the next test item in the screen to be tested.

[0013] It should be noted that the same test item has its corresponding optical parameters to be tested and test images, so there is a binding relationship between the optical parameters to be tested and the test images corresponding to the same test item. For example, when the optical parameters to be tested corresponding to the first test item are sent to the measuring instrument, the test image corresponding to the first test item will be sent to the screen to be tested; when the optical parameters to be tested corresponding to the first test item are not sent to the measuring instrument, the test image corresponding to the first test item will not be sent to the screen to be tested.

[0014] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, after obtaining the parameter value of the optical parameter to be measured corresponding to the first test item collected by the measuring instrument, the method also includes: sending a deletion instruction to the screen to be tested so that the screen to be tested deletes the test image corresponding to the first test item.

[0015] In this embodiment, after the test of a test item is completed, the test image corresponding to the test item in the screen to be tested can be deleted; compared with the processing method of overwriting the test image corresponding to the previous test item when displaying the test image corresponding to the current test item, the solution of the present application can avoid the mutual influence between the test images corresponding to multiple test items; ensure the accuracy of the test image displayed on the screen to be tested, thereby improving the accuracy of the test results.

[0016] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the pixel values ​​of different pixel positions in the test image are the same, and the test images corresponding to each test item are sent to the screen to be tested so that the screen to be tested displays the test image, including: sending the pixel value of any pixel point in the test image corresponding to each test item to the screen to be tested so that the screen to be tested displays the test image.

[0017] In this embodiment, the pixel value of a pixel point can be sent to the screen to be tested, so that the screen to be tested displays a test image according to the pixel value and a preset resolution; compared with directly sending the pixel values ​​of all pixel points of the test image, the solution of the present application can reduce the amount of data that needs to be transmitted and improve the testing efficiency of the screen to be tested.

[0018] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, at least one test item includes: one or more of: gamma curve test, contrast test, brightness uniformity test, color temperature test, color gamut test, white balance error test, and bare screen test.

[0019] In this embodiment, more executable test items can be provided, and the display performance of the screen to be tested can be tested in various dimensions; so that the display performance of the screen to be tested can be more comprehensively understood, and the accuracy of the screen test can be improved while ensuring the efficiency of the screen test.

[0026] The result generating module is used to generate the test result of the screen to be tested according to the parameter value of the optical parameter to be tested, and the test result of the screen to be tested is used to indicate the display performance of the screen to be tested.

[0027] In combination with the second aspect, in some possible implementations, if the test images corresponding to each test item include at least two identical test images, and the at least two identical test images correspond to a target test item in at least one test item, the second sending module is specifically used to: simultaneously send the optical parameters to be measured corresponding to the target test item to the measuring instrument, so that the measuring instrument simultaneously collects the parameter values ​​of the optical parameters to be measured corresponding to the target test item.

[0029] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, after obtaining the parameter value of the optical parameter to be measured corresponding to the first test item collected by the measuring instrument, the second sending module is also used to: send a deletion instruction to the screen to be tested so that the screen to be tested deletes the test image corresponding to the first test item.

[0048] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0049] Figure 1 It is a schematic diagram of an application scenario suitable for the present application, wherein the industrial computer 600 is communicatively connected with the screen to be tested 001, and is used to send a test image to the screen to be tested 001; the industrial computer 600 is communicatively connected with the measuring instrument 002, and is used to send optical parameters to be tested to the measuring instrument 002, and obtain parameter values ​​of the optical parameters to be tested collected by the measuring instrument 002.

[0050] In some related technologies, in order to conduct a comprehensive test on the display performance of the screen to be tested 001, it is necessary to measure multiple test items (for example, contrast, brightness uniformity, white balance error, etc.). In this regard, when measuring different test items, the tester needs to manually adjust the measuring instrument 002 to perform the test, collect the parameter values ​​of the optical parameters of the screen to be tested 001, and manually record the parameter values ​​of the optical parameters displayed by the measuring instrument 002 to analyze the display performance of the screen to be tested 001.

[0051] It is understandable that when the above test steps are performed manually, the operation is cumbersome. At the same time, the accuracy of manual execution is not high, and it is easy to make mistakes due to fatigue and other reasons, including the control measuring instrument 002 collecting unnecessary optical parameter values, errors in the statistical measurement of the optical parameter values ​​displayed by the measuring instrument 002, and inaccurate display performance calculated based on the optical parameter values, etc., resulting in low test efficiency.

[0052] In addition, when executing different test items, in order to reduce manual input, the screen to be tested 001 displays a random or uniform test screen, and the parameter values ​​of the optical parameters corresponding to each test item cannot be accurately obtained. The test of the display performance of the screen to be tested is inaccurate, and even if the screen to be tested 001 is detected to be qualified according to the test method, it may be a defective product, affecting the user experience.

[0053] In some related technologies, there are also solutions for autonomously detecting the screen, but usually multiple test items are tested on a group of images, and the test accuracy is low.

[0054] In this regard, the present application proposes a screen testing method, which is applied to an industrial computer 600 and combines Figure 2 The screen testing method 100 provided in the present application is described in detail.

[0055] It should be noted that, in the present application, terms such as "first" and "second" are used to distinguish different individuals in the same type of objects. For example, the first test item and the second test item represent two different test items. There is no other limitation.

[0056] Method 100 may be performed by Figure 1 The industrial computer 600 shown in FIG. Figure 2 As shown, method 100 includes the following contents.

[0057] S110, a test task is detected, where the test task includes at least one test item.

[0058] Optionally, before testing the test task, the current test environment is tested to confirm the communication status between various devices. For example, the industrial computer sends handshake information to various devices (screens to be tested and measuring instruments, etc.), and after receiving feedback on the handshake information, it is confirmed that the communication with various devices is normal, that is, the test environment is normal.

[0059] Optionally, before testing the test task, the qualification criteria of each test item can be adjusted according to the needs of the target user. For example, the natural environment in the northern and southern hemispheres is different, and the white balance parameters required for display are different. Therefore, before testing the screen to be tested, the qualification criteria of white balance are adaptively adjusted (for example, RGB values ​​under commonly used color temperatures are input), so that the display performance of the screen to be tested finally obtained better meets the needs of the target user.

[0060] Optionally, the at least one test item includes: one or more of: a gamma curve test, a contrast test, a brightness uniformity test, a color temperature test, a color gamut test, a white balance error test, and a bare screen test.

[0061] In this embodiment, more executable test items can be provided, and the display performance of the screen to be tested can be tested in various dimensions; so that the display performance of the screen to be tested can be more comprehensively understood, and the accuracy of the screen test can be improved while ensuring the efficiency of the screen test.

[0062] Exemplarily, the test items can be obtained by the tester checking them in the display interface of the industrial computer.

[0063] S120: According to at least one test item, a test image corresponding to each test item and an optical parameter to be measured corresponding to each test item are acquired.

[0064] That is, different test items are preset with targeted test images and corresponding optical parameters to be tested. After the tester checks the test item, the industrial control machine will read the test image and optical parameters to be tested corresponding to the test item and prepare for the test.

[0065] Optionally, when the test item is a gamma curve test, the corresponding test image is a set of grayscale images arranged according to grayscale values, and the corresponding optical parameter to be tested is brightness. It is used to confirm whether the brightness of the screen changes evenly when the grayscale changes in the screen to be tested, or whether the brightness change of the screen conforms to the usage habits of the target user.

[0066] Optionally, when the test item is a contrast test, the corresponding test images are a pure black image (grayscale value is 0) and a pure white image (grayscale value is 255), and the corresponding optical parameter to be tested is brightness, which is used to confirm the brightness limit of the screen to be tested. Specifically, the first brightness value of the center point of the pure white image can be obtained, and the second brightness value of the edge of the pure black image can be obtained. The contrast value calculated based on the first brightness value and the second brightness value can better reflect the brightness limit of the screen to be tested.

[0067] Optionally, when the test item is a brightness uniformity test, the corresponding test image is a pure color image, and the corresponding optical parameter to be tested is brightness, which is used to confirm whether the display brightness of the screen to be tested is uniform, or whether the brightness of each area is within a reasonable range. Specifically, the brightness values ​​of different preset points in the image can be obtained to calculate and confirm the brightness uniformity of the screen to be tested.

[0068] Optionally, when the test item is a color temperature test, the corresponding test image is a pure white image (grayscale value is 255), and the corresponding optical parameter to be measured is color temperature, which is used to confirm whether the color temperature value is within a normal and acceptable range.

[0069] Optionally, when the test item is a color gamut test, the corresponding test image is a set of RGB images, including a red image with an R value of 255, a G value and a B value of 0; a green image with a G value of 255, an R value and a B value of 0; and a blue image with a B value of 255, an R value and a G value of 0. The corresponding optical parameters to be tested are the RGB values ​​of each image, or the xy values ​​of each image in the XYZ color space, which are used to confirm the maximum color range that the screen to be tested can display.

[0070] Optionally, when the test item is a white balance error test, the corresponding test image is a set of grayscale images, and the corresponding optical parameter to be tested is chromaticity (UV value in YUV data format), which is used to confirm whether the white balance error of the screen to be tested is within an allowable range.

[0071] Optionally, when the test item is a bare screen test, the corresponding test image is a null value, that is, no test image is displayed, and the corresponding optical parameter to be tested is brightness or color temperature, which is used to confirm the general performance of the screen hardware to be tested.

[0072] S130, sending the test images corresponding to the test items to the screen to be tested, so that the screen to be tested displays the test images.

[0073] Optionally, after the test items are detected, a test item queue of the test items is generated, and the test items are executed in sequence according to the test item queue. For example, the test items are sorted by checking the order of the test items, or the test items are randomly sorted to obtain the test item queue. When sending the test images corresponding to each test item to the screen to be tested, they are sent in sequence according to the order of the test items in the test item queue. Avoid mutual influence between the test images of the test items and reduce the probability of error.

[0074] For example, if the test items include a bare screen test, the bare screen test is placed at the top of the test item queue, because the screen to be tested does not need to display any image during the bare screen test, so as to avoid other previously executed test items affecting the display image of the bare screen test, resulting in inaccurate bare screen test results.

[0075] Optionally, the pixel values ​​of different pixel positions in the test image are the same, and the test images corresponding to each test item are sent to the screen to be tested so that the screen to be tested displays the test image, including: sending the pixel value of any pixel point in the test image corresponding to each test item to the screen to be tested so that the screen to be tested displays the test image.

[0076] Exemplarily, the pixel value may be an RGB parameter value.

[0077] Exemplarily, after the screen to be tested receives the pixel value, a test image is generated according to the pixel value and preset resolution or size parameters, and finally the test image is displayed.

[0078] In this embodiment, the pixel value of a pixel point can be sent to the screen to be tested, so that the screen to be tested displays a test image according to the pixel value and a preset resolution; compared with directly sending the pixel values ​​of all pixel points of the test image, the solution of the present application can reduce the amount of data that needs to be transmitted and improve the testing efficiency of the screen to be tested.

[0079] At the same time, the test image is directly generated according to the pixel value, which can ensure the accuracy of the test image. If the complete image data is sent, due to the large amount of test image data (including the location information of each pixel point and the pixel value of each pixel point, etc.), packet loss and other problems may occur during the transmission process, causing the test image displayed on the screen to be tested to lose details, etc., resulting in inaccurate display and affecting the test results.

[0080] S140, sending the optical parameters to be measured corresponding to each test item to the measuring instrument, so that the measuring instrument collects parameter values ​​of the optical parameters to be measured.

[0081] Optionally, the measuring instrument is a color analyzer CA410.

[0082] It can be understood that when the measuring instrument collects the parameter value of the optical parameter to be measured corresponding to the test item in the screen to be measured, the screen to be measured displays the test image corresponding to the test item.

[0083] Optionally, the industrial computer sends to the measuring instrument optical parameters to be measured, for example, the test items correspond to brightness and color temperature that need to be tested.

[0084] Optionally, if the test images corresponding to each test item include at least two identical test images, and the at least two identical test images correspond to a target test item in at least one test item, the optical parameters to be measured corresponding to each test item are sent to the measuring instrument, including: simultaneously sending the optical parameters to be measured corresponding to the target test item to the measuring instrument, so that the measuring instrument simultaneously collects the parameter values ​​of the optical parameters to be measured corresponding to the target test item.

[0085] The target test items are at least two test items corresponding to the aforementioned same test image.

[0086] In this embodiment, when at least two test images are the same among the test images corresponding to the multiple test items, the at least two test items (target test items) corresponding to the test images can be tested simultaneously when the test images are displayed, that is, the measuring instrument simultaneously collects the parameter values ​​of the optical parameters to be measured corresponding to the at least two test items (target test items). Compared with executing each test item separately, this solution can reduce the test time of the screen to be tested to a certain extent and improve the test efficiency.

[0087] Exemplarily, when the test items include contrast test and color temperature test, the test images corresponding to the contrast test are pure black images and pure white images, and the test images corresponding to the color temperature test are pure white images, that is, pure white images exist in all test images. Therefore, the brightness required to be measured for the contrast test and the color temperature required to be measured for the color temperature test are sent to the measuring instrument, so that when the screen to be tested displays a pure white image, the measuring instrument simultaneously obtains the brightness value and the color temperature value, which reduces the test time of the screen to be tested to a certain extent and improves the test efficiency.

[0088] Optionally, at least one test item includes a first test item and a second test item, and sending the optical parameters to be measured corresponding to each test item to the measuring instrument includes: sending the optical parameters to be measured corresponding to the first test item to the measuring instrument; after obtaining the parameter value of the optical parameter to be measured corresponding to the first test item collected by the measuring instrument, sending the optical parameter to be measured corresponding to the second test item to the measuring instrument.

[0089] Exemplarily, obtaining the parameter value of the optical parameter to be measured collected by the measuring instrument includes actively sending a query message to the measuring instrument or receiving active feedback from the measuring instrument.

[0090] In this embodiment, when executing multiple test items, another test item can be executed after one test item is completed, thereby avoiding mutual interference between the multiple test items and improving the accuracy of the test.

[0091] In one possible implementation, whether the current test item has been completed is determined by determining whether the parameter value of the optical parameter to be tested corresponding to the current test item is received; after completing the test of the current item, the optical parameter to be tested corresponding to the next test item is sent to the measuring instrument; and a test image corresponding to the next test item is sent to the screen to be tested, so that the measuring instrument obtains the parameter value of the optical parameter to be tested corresponding to the next test item in the screen to be tested.

[0092] It can be understood that the same test item has its corresponding optical parameters to be measured and measured images, so there is a binding relationship between the optical parameters to be measured and the measured images corresponding to the same test item, for example, a binding relationship of sending time.

[0093] Exemplarily, when the optical parameters to be measured corresponding to the first test item are sent to the measuring instrument, the test image corresponding to the first test item is sent to the screen to be tested; when the optical parameters to be measured corresponding to the first test item are not sent to the measuring instrument, the test image corresponding to the first test item is not sent to the screen to be tested. When the measuring instrument tests the screen to be tested according to the optical parameters to be tested corresponding to the first test item, the screen to be tested is displaying the test image corresponding to the first test item, thereby ensuring the accuracy of the test.

[0094] Optionally, after obtaining the parameter value of the optical parameter to be measured corresponding to the first test item collected by the measuring instrument, the method further includes: sending a deletion instruction to the screen to be measured, so that the screen to be measured deletes the test image corresponding to the first test item.

[0095] In the present embodiment, after the test of a test item is completed, the test image corresponding to the test item in the screen to be tested can be deleted; compared with the processing method of overwriting the test image corresponding to the previous test item when displaying the test image corresponding to the current test item, the solution of the present application can avoid the mutual influence between the test images corresponding to multiple test items; ensure the accuracy of the test image displayed on the screen to be tested, thereby improving the accuracy of the test results.

[0096] S150, obtaining parameter values ​​of the optical parameters to be measured collected by the measuring instrument.

[0097] For example, after the measuring instrument completes the collection of the optical parameters to be measured sent by the industrial computer, the parameter values ​​of the collected optical parameters to be measured will be fed back to the industrial computer, so that the industrial computer can record and analyze relevant data to determine the display performance of the screen to be measured. Alternatively, after the industrial computer sends the optical parameters to be measured to the measuring instrument, the parameter values ​​of the optical parameters to be measured collected by the measuring instrument will be actively queried at a preset time.

[0098] Among them, when the size of the screen to be measured is large, more points need to be measured, and the amount of data of the parameter values ​​of the optical parameters to be measured is also relatively large. It is easy to miss when recording manually, and the probability of error is high. However, directly transmitting the parameter values ​​of the relevant optical parameters to be measured to the industrial computer can avoid omissions, and the data that can be retained is high in accuracy.

[0099] S160, generating a test result of the screen to be tested according to the parameter value of the optical parameter to be tested, wherein the test result of the screen to be tested is used to indicate the display performance of the screen to be tested.

[0100] That is, the industrial computer analyzes the collected parameter values ​​of the optical parameters to be tested and confirms the display performance of the screen to be tested. For example, a test report is generated, and the test report displays the parameter values ​​of the optical parameters to be tested and the evaluation results of the display performance.

[0101] Exemplarily, when the test item in the test task is a gamma curve test, the corresponding test image is a set of grayscale images arranged evenly in the order of grayscale values, and the difference in grayscale values ​​between two adjacent grayscale images is equal. For example, the test image is 256 grayscale images arranged according to grayscale values ​​of 0-255, and the difference in grayscale values ​​between two adjacent grayscale images is 1, or 128 grayscale images arranged according to grayscale values ​​of 0, 2, 4, 6...255, and the difference in grayscale values ​​between two adjacent grayscale images is 2. If the difference in grayscale values ​​between two adjacent grayscale images is equal, the change in grayscale is uniform. The parameter value of the optical parameter to be measured collected is the brightness value corresponding to each grayscale image, which can be the brightness value of the same pixel point in different grayscale images.

[0102] According to the changing trend of the brightness value, the test result of the screen to be tested is obtained. For example, the difference in brightness values ​​corresponding to two adjacent grayscale images is obtained to confirm whether each difference is within the allowable range. For example, the allowable difference between grayscale images with smaller grayscale values ​​is larger, and the allowable difference between grayscale images with larger grayscale values ​​is smaller. If so, the test result of the screen to be tested is generated, indicating that the gamma curve test is qualified. Alternatively, a gamma curve is drawn according to the grayscale value corresponding to the grayscale image and the obtained brightness value to confirm whether the parameter value of the gamma curve is within the allowable range. If so, the test result of the screen to be tested is generated, indicating that the gamma curve test is qualified.

[0103] In addition, when the difference between the obtained parameter value of the optical parameter to be measured and the preset standard value is greater than the preset threshold, it is confirmed whether the measurement environment is abnormal. After eliminating the environmental factors, the test can be repeated.

[0104] In the above method, a test task is obtained according to the test item selected by the user, a test image corresponding to the test item is sent to the screen to be tested, and the optical parameter to be tested corresponding to the test item is sent to the measuring instrument, so that when the screen to be tested displays the test image corresponding to the test item, the measuring instrument tests the screen to be tested that is currently displaying the test image, and obtains the parameter value of the optical parameter to be tested corresponding to the test item; the test result of the screen to be tested is generated according to the parameter value of the optical parameter to be tested obtained by the measuring instrument, indicating the display performance of the screen to be tested. In the method of the present application, on the one hand, since the test method of the present application does not require human intervention, it can send the test image corresponding to the test item to the screen to be tested based on the test item in the test task, and can send the optical parameter to be tested corresponding to the test item to the measuring instrument based on the test item in the test task, so as to realize automatic testing of the screen to be tested, reduce manpower input, and improve testing efficiency; on the other hand, in this case, when testing the screen to be tested, for each test item in at least one test item, the test image corresponding to each test item and the parameter value of the optical parameter to be tested can be obtained; through the test image corresponding to each test item and the parameter value of the optical parameter to be tested, targeted testing of the test item is realized, so that the test result of each test item obtained is more accurate; by improving the accuracy of each test item, the accuracy of the test result of the screen to be tested can be improved; while ensuring the efficiency of screen testing, the accuracy of screen testing is improved.

[0105] For example, Figure 3 An operable interface for a screen testing method proposed in the present application includes a test item check area 11 , a test result display area 12 , a personalized adjustment area 13 , and a control start area 14 .

[0106] Among them, the test item check area 11 is used for the tester to confirm the test items that need to be tested on the screen to be tested; the test result display area 12 is used to display the test results of the final screen to be tested; the personalized adjustment area 13 is used to adjust the judgment criteria of the test items according to user needs; the control start area 14 is used to control the start and stop of the test task, etc.

[0107] Exemplarily, in the personalized adjustment area 13, the Gamma order item is to set the number of grayscale images in the gamma curve test according to user needs.

[0108] Test platforms such as 982, 972, 9950, 811, etc., indicate the model of the image processing chip of the screen to be tested. After selecting the 982 or 972 platform, no special processing is required. After selecting the 9950 or 811 platform, a trigger message needs to be sent to trigger the external proxy platform to start, and send data to the screen to be tested through the external proxy platform.

[0109] When the white balance needs to be corrected, you need to enter the standard RGB, cold RGB and warm RGB of the target white balance to adjust the test standard in the white balance error test. The white balance can be corrected accordingly according to the geographical environment where the user is located.

[0119] It should be noted that S203 and S204 can be executed simultaneously, that is, the industrial computer sends the test image corresponding to the first test item to the screen to be tested, and at the same time sends the optical parameter to be tested corresponding to the first test item to the measuring instrument, so that when the measuring instrument collects the parameter value of the optical parameter to be tested of the screen to be tested, the screen to be tested displays the test image corresponding to the first test item.

[0120] S205: Display a test image corresponding to the first test item.

[0127] Exemplarily, in this embodiment, the second test item is tested after the first test item is tested, so as to avoid mutual interference between parameters (test images, etc.) between the test items and improve the accuracy of the test results.

[0128] Exemplarily, the parameter value of the optical parameter to be measured corresponding to the first test item obtained by the industrial computer is used as an indication that the test of the first test item is completed.

When the measuring instrument collects the parameter value of the optical parameter to be tested corresponding to the second test item, the screen to be tested displays the test image corresponding to the second test item.

[0134] If it is set to send simultaneously, after receiving the optical parameters to be tested of the first test item, the industrial computer is triggered to simultaneously send the test image and the optical parameters to be tested corresponding to the second test. The logic setting of data sending is simple, and there is no need to set the sequence and disaster recovery delay.
