[0081] The objectives, functional characteristics and advantages of the present application will be further described with reference to the accompanying drawings in conjunction with embodiments. DETAILED DESCRIPTION

[0082] In order to make the above objectives, characteristics and advantages of the present application more apparent, clear and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0083] At present, the display screen quality detection mainly adopts the manual detection method. Specifically, the manual detection method refers to that a technician observes whether the display screen entity has display failure through naked eyes on the production line, so as to evaluate the display screen quality. However, this method is greatly affected by subjective factors, resulting in low accuracy of display screen quality detection.

[0084] The embodiments of the present application provide a display screen quality detection method, applied to a quality detection device. In the first embodiment of the display screen quality detection method of the present application, with reference to Figure 1 , the display screen quality detection method comprises the following steps.

[0085] In step S10, if the quality detection request signals of the to-be-tested display screens are received, the power-on / off detection is performed on each of the to-be-tested display screens, and the corresponding power-on / off detection result is obtained.

[0086] In step S20, based on the power-on / off detection result, the corresponding camera of each of the to-be-tested display screens is controlled to perform image acquisition, and the corresponding display screen image is obtained.

[0087] In step S30, the image similarity of each of the display screen images is obtained, and according to the image similarity, the screen detection is performed on the corresponding to-be-tested display screen, and the corresponding screen detection result is obtained.

[0088] In step S40, according to the screen detection result and the power-on / off detection result, the quality grade of the corresponding to-be-tested display screen is determined.

[0089] In the present embodiment, it is necessary to refer to Figure 2It can be known that the quality detection device can include a test platform G110, the camera G120, the power control G130, and the display screen to be tested G140. The test platform can be a SkyRobot automatic test platform. The test platform is used to control the power control to perform a cycle power on-off. The camera is used to take a display screen image of the display screen to be tested. The quality detection device can simultaneously detect the display screen quality of multiple display screens to be tested. That is, the number of cameras and the number of power on-off controls in the quality detection device are set synchronously with the number of display screens to be tested. In Figure 2 only two display screens to be tested are listed in the description. In order to further ensure the accuracy of the display screen quality detection, thousands of on-off detection and screen detection can be performed on each display screen to be tested. The on-off detection result can include on-off time information and on-off stability information, which are used to represent the on-off performance of each display screen to be tested. The image similarity can be understood as an evaluation index of the display screen quality, which is used to perform screen detection on the display screen to be tested, that is, to determine whether the display screen to be tested appears black screen or screen.

[0090] As an example, steps S10 to S40 include: if it is detected that each display screen to be tested is placed on the detection table, the quality detection request signal can be triggered by clicking the start detection button on the detection table. When the test platform receives the quality detection request signal, the corresponding power control of each display screen to be tested is controlled to perform a cycle power on-off for on-off detection, so as to obtain corresponding on-off time information and on-off stability information. If each display screen to be tested is normally started, the corresponding camera of each display screen to be tested is controlled to take an image, so as to obtain a corresponding display screen start image. A third-party test library such as sikuli is called, and the image similarity of each display screen image can be directly calculated. According to the image similarity, screen detection is performed on the corresponding display screen to be tested to determine whether the display screen to be tested appears black screen or screen, so as to obtain a corresponding screen detection result. The screen detection result includes a black screen detection result and a screen detection result. The black screen detection result corresponds to black screen frequency information, and the screen detection result corresponds to screen frequency information. According to the black screen frequency information, the screen frequency information, the on-off time information, and the on-off stability information, a corresponding quality level is queried in a preset quality evaluation table. The quality level is obtained according to the four evaluation indexes of black screen frequency information, screen frequency information, on-off time information, and on-off stability information. The quality level can include high quality, medium quality, and low quality.

[0091] The screen detection result includes a black screen detection result and a screen detection result. The step of performing screen detection on the corresponding display screen to be tested according to the image similarity to obtain a corresponding screen detection result includes:

[0092] The step of controlling each camera corresponding to each display screen under test to capture images based on each of the power-on / off detection results to obtain each display screen image comprises:

[0093] In step S21, a waiting mode is started based on each of the power-on / off detection results.

[0094] In step S22, a waiting time corresponding to the waiting mode is obtained, and it is detected whether the waiting time reaches a preset waiting time.

[0095] In step S23, if yes, each camera is controlled to capture images to obtain corresponding display screen images.

[0096] In this embodiment, it should be noted that, during the power-on process of the display screen under test, other images such as product LOGO images may appear, and the display screen image captured in this embodiment is a display screen power-on image, that is, the initial image of the display screen under test after normal power-on. Only after the user performs remote control or voice operation, the initial image will change. In order to further ensure the accuracy of the display screen quality detection, a preset waiting time is set in this embodiment to achieve the purpose of ensuring that the captured display screen image is an initial image.

[0097] As an example, steps S21 to S23 comprise: if each of the power-on / off detection results is obtained, it indicates that each of the display screens under test is normally powered on, and then the waiting mode is started. The waiting mode means that the quality detection device suspends the quality detection process until the waiting time corresponding to the waiting mode reaches the preset waiting time. The preset waiting time is an experienced value set by a person skilled in the art according to the product performance of the display screen under test, that is, the initial image of the display screen under test will appear within a certain time. When the waiting time reaches the preset waiting time, the subsequent quality detection process is started, that is, each camera is controlled to capture images to obtain corresponding display screen images.

[0098] For example, assuming that the preset waiting time is 75 seconds, when the display screen 1 under test is normally powered on, the detection platform enters the waiting mode, and when the waiting time reaches 75 seconds, the camera corresponding to the display screen 1 under test is controlled to capture the display screen image thereof.

[0099] The step of obtaining the image similarity of each display screen image comprises:

[0100] In step S31, it is detected whether each display screen image is a preset normal display screen image.

[0101] In step S32, if yes, similarity detection is performed on each display screen image to obtain a corresponding image similarity.

[0102] Step S33, if no, the system is warned.

[0103] In the embodiment, it is to be noted that before the similarity detection, it is needed to judge whether each display screen image is a preset normal display screen image, if each display screen image is abnormal, such as the displayed image is incomplete or a black and white image, it is indicated that each display screen to be tested has a display failure at this time, and a warning is directly performed, and the specific process can refer to Figure 3 , and the subsequent similarity detection is not performed, the storage resource of quality detection is saved, and the efficiency of display screen quality detection is improved; the preset normal display screen image refers to an initial picture image of the display screen to be tested after normal booting.

[0104] As an example, steps S31 to S33 include: comparing each display screen image with the preset normal display screen image to detect whether each display screen image is a preset normal display screen image; if yes, it is indicated that each display screen is normally booted at this time, and the similarity detection is performed on each display screen image to obtain a corresponding image similarity; if no, it is indicated that each display screen has a display failure at this time, and the system is warned.

[0105] Step S34, according to each image similarity, it is detected whether the corresponding display screen to be tested has a black screen.

[0106] Step S35, if the black screen appears, the current black screen picture of the display screen to be tested and a corresponding first time stamp record are recorded as the black screen detection result, and a black screen warning is performed.

[0107] Step S36, if the black screen does not appear, according to each image similarity, it is detected whether the corresponding display screen to be tested has a screen flower.

[0108] Step S37, if the screen flower appears, the current screen flower picture of the display screen to be tested and a corresponding second time stamp record are recorded as the screen flower detection result, and a screen flower warning is performed.

[0109] As an example, the steps S34 to S37 include: detecting whether the corresponding to-be-tested display screen appears black screen according to the image similarities and a preset first similarity, wherein the preset first similarity refers to a similarity value of appearing black screen which is set in advance according to the iteration information of the to-be-tested display screen and product performance, and the value is an empirical value which can be adjusted according to actual conditions; if the black screen appears, the current black screen picture of the to-be-tested display screen and the corresponding first time stamp are recorded as the black screen detection result, and an email is sent to the relevant management personnel for early warning, and light early warning or voice broadcast early warning can also be performed, and the early warning form is not limited; wherein the first time stamp refers to the current time corresponding to the current black screen picture; if the black screen does not appear, the corresponding to-be-tested display screen is further detected whether the corresponding to-be-tested display screen appears a screen with a pattern according to the image similarities and a preset second similarity, wherein the second similarity value refers to a similarity value of appearing a screen with a pattern, and the specific meaning is the same as that of the preset first similarity value; if the screen with a pattern appears, the current screen with a pattern picture of the to-be-tested display screen and the corresponding second time stamp are recorded as the screen with a pattern detection result, and an email is sent to the relevant management personnel for screen with a pattern early warning, wherein the second time stamp refers to the current time corresponding to the current screen with a pattern picture; if the screen with a pattern does not appear, that is, the to-be-tested display screen all appears black screen and screen with a pattern, it is indicated that the to-be-tested display screen is normal.

[0110] The step of detecting whether the corresponding to-be-tested display screen appears black screen according to the image similarities includes:

[0111] The step S311 includes: detecting whether the image similarities are greater than a preset first similarity.

[0112] The step S312 includes: if yes, it is determined that the corresponding to-be-tested display screen does not appear black screen.

[0113] The step S313 includes: if no, it is determined that the corresponding to-be-tested display screen appears black screen.

[0114] As an example, the steps S311 to S313 include: detecting whether the image similarities are greater than a preset first similarity; if the image similarities are greater than the preset first similarity, it is determined that the corresponding to-be-tested display screen does not appear black screen, and it is further detected whether the to-be-tested display screen appears a screen with a pattern; if the image similarities are less than or equal to the preset first similarity, it is determined that the corresponding to-be-tested display screen appears black screen, and the current black screen picture and the corresponding first time stamp are recorded, and early warning is performed.

[0115] For example, refer to Figure 4Assuming the preset first similarity is 0.7 or 70%, if the calculated image similarity of the display screen 1 under test is 0.65, which is less than 0.7, then it is determined that the display screen 1 under test has a black screen, the black screen image at this time and the current computer time are recorded, and an alert is issued; if the calculated image similarity of the display screen 1 under test is 0.8, which is greater than 0.7, then it is determined that the display screen 1 under test has not a black screen, and then further detection is performed to see if the display screen 1 under test has a distorted screen.

[0116] The step of detecting whether the corresponding display screen to be tested has a distorted image based on the similarity of each image includes:

[0117] Step S331: Detect whether the similarity of each image is greater than a preset first similarity.

[0118] Step S332: If yes, then determine that the corresponding display screen under test has not shown a black screen;

[0119] Step S333: If not, then determine that the corresponding display screen under test is black.

[0120] As an example, steps S331 to S333 include: detecting whether the similarity of each image is greater than a preset second similarity; if the similarity of each image is greater than the preset second similarity, it is determined that the corresponding display screen under test has not shown a black screen, and at this time it is necessary to further detect whether the display screen under test has a distorted screen; if the similarity of each image is less than or equal to a preset first similarity, it is determined that the corresponding display screen under test has a black screen, and the current black screen image and the corresponding first timestamp are recorded, and an early warning is issued.

[0121] For example, refer to Figure 4 Assuming the preset second similarity is 0.94 or 94%, if the calculated image similarity of the display screen 1 under test is 0.8, which is less than 0.94, then it is determined that the display screen 1 under test has a distorted screen, the distorted screen image and the current computer time are recorded, and an alert is issued; if the calculated image similarity of the display screen 1 under test is 0.99, which is greater than 0.94, then it is determined that the display screen 1 under test has not a distorted screen, indicating that the display screen 1 under test is normal.

[0122] The power-on / off test results include power-on / off duration information and power-on / off stability information. The step of determining the quality level of the corresponding display screen under test based on the screen test results and the power-on / off test results includes:

[0123] Step S41: Obtain the black screen count information corresponding to each of the black screen detection results, and the screen flickering count information corresponding to each of the screen flickering detection results;

[0124] Step S42, according to each of the black screen times information, each of the screen times information, each of the switch time information and each of the switch stability information, matching the corresponding quality level of the to-be-tested display screen in the preset quality evaluation table.

[0125] In the embodiment, it is to be noted that the switch time information refers to the average boot time of each of the to-be-tested display screens; the switch stability information refers to the boot time stability of each of the to-be-tested display screens, wherein the boot time stability refers to the standard deviation obtained by normal distribution of the boot time of each of the to-be-tested display screens; the black screen times information is used to represent the number of times of black screen of each of the to-be-tested display screens; the screen times information is used to represent the number of times of screen of each of the to-be-tested display screens; in order to better evaluate the display screen quality, the preset quality evaluation table can be established, which can refer to Figure 5 , the preset quality evaluation table is used to evaluate the quality level of each to-be-tested display screen according to four evaluation indexes of black screen times information, screen times information, average boot time and boot time stability, and to formulate corresponding evaluation rules, such as black screen times 0, screen times 0, average boot time 70 seconds and boot time stability less than or equal to 5 seconds, quality level high quality, black screen times 0, at most 1 screen, average boot time 80 seconds and boot time stability less than or equal to 10 seconds, quality level medium quality, at most 1 black screen, at most 1 screen, average boot time 90 seconds, boot time stability less than or equal to 20 seconds, quality level low quality. For details, please refer to Figure 2 .

[0126] As an example, steps S41 to S42 include: obtaining the recording times of each of the current black screen pictures, taking the recording times as the black screen times, obtaining the recording times of each of the current screen pictures, taking the recording times as the screen times; according to each of the black screen times information, each of the screen times information, each of the average boot time and each of the boot time stability, matching the corresponding quality level in the preset quality evaluation table.

[0127] After the step of determining the quality level of the corresponding to-be-tested display screen according to each of the screen detection results and each of the switch detection results, the method further comprises:

[0128] Step A10, packaging the corresponding screen detection result, the corresponding switch detection result and the corresponding quality level of each of the to-be-tested display screens to obtain a data packet;

[0129] Step A20, sending the data packet to a preset display platform, the preset display platform is used to visually display the data packet.

[0130] In the embodiment, it should be noted that, since the display screen quality detection is performed by artificial detection in the prior art, in order to improve the intelligence of the display screen quality detection, the screen detection result, the power-on / off detection result and the quality level of each display screen to be detected are visualized in a preset display platform in the embodiment, so as to realize the purpose of remotely observing the quality detection result of each display screen to be detected; for reference Figure 2 , the preset display platform can be an online SkyGrafana display system, which includes a display screen real-time display module G510 / G520 and a mysql database G530, wherein the display screen real-time display module is used to call the data packet in the mysql database and display the content in the data packet, and the mysql database stores the data packet corresponding to each display screen to be detected transmitted by the quality detection equipment; for reference Figure 6 .
