[0002] After a display screen is manufactured, it is usually necessary to detect the display function and appearance of the display screen to avoid display function defects or appearance defects in the display screen.

[0003] In the existing detection of display screen defects, when it is detected that the display screen has a display function defect or an appearance defect, it is necessary for a human to use measuring tools such as a grid or a measuring instrument to measure the defect position, use a marker pen to mark the defect position, mark the size, position, and defect type of the defect, etc., and record the defect information. However, the display screen defects may be relatively small defects such as points or lines, which may cause inaccurate manual measurement and marked positions, and it is more troublesome to use various tools for measurement, thus affecting the efficiency of display screen defect detection and marking. Summary of the Invention

[0004] In view of this, the present invention aims to provide a method for marking display screen defects, a device for marking display screen defects, an electronic device, and a computer-readable storage medium, which are used to improve the problems of low efficiency of display screen defect detection and marking and low marking accuracy rate in the process of manually marking the defects existing in the display screen in the prior art.

[0005] In a first aspect, an embodiment of the present application provides a method for marking display screen defects, including: creating a marking layer corresponding to the size of the display screen, where the marking layer is used to be displayed on the display screen; marking a first position on the marking layer based on a control instruction of a user, where the first position is used to represent the corresponding position of the position where the display screen defect is located on the marking layer.

[0006] In the embodiment of the present application, by creating a marking layer corresponding to the size of the display screen and displaying it on the display screen, so that after the user determines the defects existing in the display screen, the user can mark on the marking layer. Since the marking layer corresponds to the display screen, compared with the prior art, there is no need for a human to use tools to measure and mark on the display screen, and accurate marking can be directly performed on the marking layer corresponding to the display screen, thereby improving the accuracy and efficiency of marking.

[0007] In one embodiment, before marking the first position on the marking layer based on the user's operation, the method further includes: generating a detection image for detecting defects of the display screen, the detection image being used for display on the display screen so that the user can determine the location of the display screen defect based on the detection image, wherein the detection image is displayed overlapping with the marking layer, the marking layer is transparent and the transparency is a preset value, and the marking layer floats above the detection image.

[0008] In the embodiments of the present application, a detection image is generated and displayed on the display screen to detect whether there are defects in the display function of the display screen through the detection image, thereby facilitating the user to determine the location of the display screen defect and mark it.

[0009] In one embodiment, the marking of the first position on the marking layer includes: generating a marking symbol for marking the first position based on the user's selection, and the center of the marking symbol coincides with the center of the defect.

[0010] In the embodiments of the present application, by making the center of the marking symbol coincide with the center of the first position corresponding to the defect location, the accuracy of defect marking can be improved to a certain extent.

[0011] In one embodiment, after generating a marking symbol for marking the first position based on the user's selection, the method further includes: generating an associated information annotation of the marking based on the first position and the marking symbol.

[0012] In the embodiments of the present application, the associated information annotation is automatically generated based on the marking symbol and the first position. Compared with the prior art where manual annotation is performed, the process of manually measuring the defect location can be reduced, the workload can be reduced, thereby improving the efficiency of annotating the display screen defect. At the same time, human errors in the manual annotation process are reduced, further improving the accuracy of defect marking.

[0013] In a second aspect, the embodiments of the present application provide a display screen defect marking device, including: a marking layer unit for creating a marking layer corresponding to the size of the display screen, the marking layer being used for display on the display screen; a marking unit for marking the first position on the marking layer based on the user's selection, the first position being used to represent the corresponding position of the location of the display screen defect on the marking layer.

[0014] In one embodiment, the marking unit includes: a marking symbol module for generating a marking symbol for marking the first position based on the user's selection, and the center of the marking symbol coincides with the center of the defect.

[0015] In one embodiment, the marking unit further includes: a marking generation module, configured to generate an association information marking of the mark based on the first position and the marking symbol.

[0016] In one embodiment, the display defect marking device further includes: a storage unit, configured to save the marked marking layer.

[0017] In the embodiments of the present application, by saving the marked marking layer, compared with the prior art of marking on the display screen with a marker pen, the file generated by the marking layer is easier to save, and it can also avoid the pollution caused by the marking to the display screen.

[0018] In a third aspect, the embodiments of the present application provide an electronic device, including a memory and a processor. Computer-readable instructions are stored in the memory. When the computer-readable instructions are executed by the processor, the processor is caused to execute the functions of a display defect marking device as described in the first aspect or implement a display defect marking method as described in the second aspect.

The specific implementation process of this method can refer to Figure 2 for the specific content, which will not be elaborated here. The processor of the electronic device is used to provide computing and control capabilities to support the operation of the entire electronic device. The internal memory can store computer-readable instructions. When the computer-readable instructions are executed by the processor, the processor can be made to execute a method for marking display screen defects. Those skilled in the art can understand that Figure 1 the structure shown in

The specific electronic device may include more or fewer components than those shown in the figure, or combine some components, or have different component arrangements.

[0036] The input device 130 is for user use, enabling the user to input control instructions and enter information, so as to mark the defects of the display screen. Specifically, the input device may include a two-dimensional pointer device, a keyboard, and a barcode scanning device. The two-dimensional pointer device may be a mouse, a trackball, a touchpad, a touch screen, etc.

[0038] A communication module 150 for connecting the display screen detection device to the server and uploading the detection results of the display screen stored in the memory 140 to the server. Specifically, the communication module 150 can include an Ethernet module, Wi-Fi module, 4G module, 5G module, etc.

[0039] Please refer to Figure 2 , Figure 2 which is a flowchart of a method for marking display screen defects provided by an embodiment of the present application. The method includes:

[0040] S110: Create a marking layer corresponding to the size of the display screen, and the marking layer is used to be displayed on the display screen.

[0041] Please refer to Figure 3 , Figure 3 which is a schematic diagram of the marking layer provided by an embodiment of the present application.

[0042] In this embodiment, after the user creates the marking layer and before operating on the marking layer, the marking layer can be presented as a colorless and transparent top floating window. It can be understood that the top floating window is similar to a colorless transparent film and can be displayed on the display screen. Specifically, the marking layer can be fully transparent (i.e., the transparency is 100%) or have a certain transparency (i.e., the transparency can be 1% - 99%). When the user does not operate on the marking layer, the marking layer can be fully transparent. When the user uses the marking layer or operates on the marking layer, the marking layer can be displayed as a top floating window with a certain transparency or a top floating window with a background color and a certain transparency, so that the user can distinguish the marking layer from other displayed contents. In some implementation cases, when the user operates on the marking layer, the marking layer can also be a colorless and transparent top floating window with a specific color border. It can be understood that the transparency of the marking layer can be reasonably adjusted without affecting the user's detection of display screen defects.

[0043] In this embodiment, the electronic device can create a marking layer based on the user's control. The marking layer is used for display on the display screen. When creating the marking layer, the user can set parameters corresponding to the size of the display screen, so as to create a marking layer of the corresponding size. Thus, when there are defects on the display screen, marks can be made at the corresponding positions on the marking layer. Specifically, a marking layer with the same length and width as the display screen is created according to the length and width of the display screen. Thus, when the marking layer is displayed on the display screen, each position of the display screen corresponds to each position of the marking layer. Thus, when there are defects on the display screen, marking the corresponding positions on the marking layer is equivalent to marking the positions where the defects of the display screen are located.

[0044] In one embodiment, before the user marks the defects of the display screen, a detection image for detecting the defects of the display screen is generated. The detection image is used for display on the display screen so that the user can determine the location of the defects of the display screen based on the detection image. The detection image and the marking layer are overlapped and displayed. The marking layer is transparent and has a preset transparency value, and the marking layer floats above the detection image.

[0045] Generally, when detecting the defects existing on the display screen, a detection image is used. The detection image can be a pure color image of red, yellow, blue, black, or white, or an image with a specific pattern such as a checkerboard. The detection image is used for display on the display screen. Since the detection image has a specific color or pattern, when the detection image is displayed on the display screen, the defects existing on the display screen can be revealed. For example, when using a pure white detection image to detect the display screen, the positions of the defects on the display screen may not be able to display white normally and display other colors. The user can then determine that the positions on the display screen where other colors are displayed are the defect positions. During the detection, the user can also adjust the gray scale of the displayed image through the input device 130, adjusting the gray scale within the range of 0-100 to detect the display function of the display screen under different gray scale values. Specifically, adjusting the gray scale can be done by increasing or decreasing the gray scale through the keyboard or by adjusting it with the mouse wheel.

[0046] In this embodiment, the detection image can be set in advance or generated in real time. If the detection image is set in advance, the detection image is stored in the memory. When in use, the processor can directly call the required detection image, and the processor sends the called detection image to the image generation unit so that the detection image is displayed on the display screen.

[0047] In this embodiment, the marking layer is independent of the detection image, and the user can operate on the marking layer and the detection image separately. Since the marking layer can be displayed as a fully transparent and colorless layer, when the marking layer can be suspended above the detection image, it does not affect the normal display of the detection image and the user's judgment of defects. Specifically, when detecting the display screen, detections of different colors and patterns are required. Since the marking layer is a fully transparent layer, it can avoid the abnormality of the detection image seen by the user due to the color of the marking layer.

[0048] During the detection process, different detection images are needed to detect screen defects. Therefore, the marking layer and the detection image can be operated separately. It can be understood that during the detection, usually different detection images need to be displayed on the same display screen to detect different types of display screen defects. Therefore, the separate operation of the marking layer can also concentrate the defects existing in the same display screen detected by different detection images on one layer, facilitating the preservation of defect marking data and the viewing of the positions where defects exist.

[0049] S120. Mark the first position on the marking layer based on the user's operation. The first position is used to represent the corresponding position of the location where the display screen defect is located on the marking layer.

[0050] In this embodiment, after the user determines the defects existing in the display screen through the detection image, the user can mark the corresponding position of the display screen defect position on the marking layer. As Figure 4 shown, when the detection image displayed on the display screen is abnormal, such as bright lines and bright spots, the user can select the corresponding position on the marking layer to mark the defect position.

[0051] In one embodiment, a marking symbol for marking the first position is generated based on the user's selection, and the center of the marking symbol coincides with the center of the defect.

[0052] In this embodiment, after the user determines the defect location, the user can use the input device to select the first position corresponding to the display screen defect on the marking layer, and select the type of marking symbol, and create the selected marking symbol at the first position on the marking layer. The electronic device generates a marking symbol at the first position according to the user's selection. Specifically, the marking symbols preset are stored in the memory. For example, the marking symbols can have styles such as circles, ellipses, and squares. The user can select the marking symbol of the required style, and use the input device to select the location of the defect, and issue an instruction to create the selected marking symbol. The electronic device generates the marking symbol of the style selected by the user at the first position according to the received instruction. After creating the marking symbol, the user can select the created marking symbol and modify it, such as modifying the color, modifying the size, moving the position, etc. For example, change the color of the marking symbol, select the marking symbol and drag it to move the position of the marking symbol, or click on the marking symbol, and draggable points appear above, below, left, and right of the marking symbol. Dragging this point can modify the size of the marking symbol.

[0053] In this embodiment, when the marking symbol is generated or modified, the center point of the marking symbol will be displayed. The user can move the center point to the center of the defect, thereby realizing the coincidence of the center of the marking symbol and the center of the defect, so that the marking is more accurate.

[0054] In this embodiment, the connection lines between the marking symbols can also be set. The connection lines are used to represent the relationship between the connected marking symbols. For example, when two defects are detected on the display screen based on the same detection image, after marking the defects, the marking symbols of the two defects can be connected by the connection lines to represent that these two defects belong to the same type of defect. In addition, the user can add annotations. The annotations are used to record defect information or detection-related information, and through the connection lines, the relationship between the marking symbols and the annotations is established, so that the annotations can explain the marking symbols.

[0055] In one embodiment, the association information annotation is marked based on the association between the first position and the marking symbol generation.

[0056] In this embodiment, after the first position is marked by the marking symbol, the electronic device can generate the corresponding association information annotation according to the type of the marking symbol and the coordinates of the unique position. Such as Figure 4 when the marking symbol is the ellipse in the figure, it can be determined that the defect is a line and the corresponding annotation is generated. When the marking symbol is the small circle in the figure, it can be determined that the defect is a point and the corresponding annotation is generated. The corresponding annotation can also be generated according to the type of the detection image during marking. For another example, when the detection image is a pure black image and the defect is marked, the generated annotation can be a bright point or a bright line, etc.

[0057] In this embodiment, a complete annotation may include defect information (such as dark spots, bright spots, bright lines, etc.), defect positions, and marked graphic information (graphic shape, X-axis length / side length, Y-axis length / side length, graphic color, detection image. Please refer to Figure 4 , Figure 4 For an example of a display defect mark, the associated information annotation content can be understood as follows: The types of both defects are dark spots. The centers of the positions of the two defects in the coordinates of the screen are (13, 9) and (4, 22) respectively. The shapes of the marked graphics are both oval C. In the annotation, (2, 2, B) indicates that the detailed features are that the X-axis length and Y-axis length are 2, the marked color is black B, and W indicates that the detection image used is white. It can be understood that the electronic device can generate annotation information that conforms to the actual situation of the defect. Among them, the defect position coordinates can take any vertex of the display screen as the origin, establish a coordinate system, and use the position where the defect center is located as, and determine it as the coordinates of the defect position.

[0058] In this embodiment, after the user confirms that the display defects detected in a detection image are marked, the detection image can be switched so that the user can mark the display defects detected in other detection images.

[0059] In this embodiment, after the display screen is detected by all detection images, the electronic device automatically records all the marks and the corresponding annotation information, and saves the marked layer and the recorded mark annotations as a defect record file for the user to view the information of the display screen. In addition, in the defect record file, the last saved time of the display defect mark record can also be recorded, as well as information such as the display screen number, QR code, barcode, serial number, etc., so that the data of each file can correspond to the display screen.

[0060] In this embodiment, after saving the display defect information as a file, the electronic device can upload the defect record file to a remote server for storage through the communication module 150 for query and verification.

[0061] In one embodiment, after detecting the display screen using all the detected images and saving the defects as a defect record file, the display screen can also be rejudged. The rejudgment process may include: reading the number, QR code, barcode, and serial number of the display screen and selecting rejudgment; requesting the defect record file corresponding to the display screen from the server; creating a marking layer, and drawing all marking symbols and generating corresponding annotations on the marking layer according to the defect information in the defect record file; since the defect record file records the marking symbols and annotations, and the annotations record the detected images corresponding to the existing defects, therefore, according to the information in the defect record file, the detected images in which the display screen is detected to have display defects can be determined, and the detected images are displayed so that the user can judge whether there are defects characterized by the marking symbols and annotations; when the rejudged defects are consistent with the defects detected for the first time, then switch to the next detected image, and when they are inconsistent, modify the corresponding marks; after all the detected images in which the display screen is detected to have display defects are used to detect the display screen again, a rejudgment defect record file is generated; if the rejudgment defect record file is inconsistent with the defect record file detected for the first time, then upload the rejudgment defect record file to the server for storage.

[0062] In the embodiment of the present application, by creating a marking layer corresponding to the size of the display screen and displaying it on the display screen, so that the user can mark on the marking layer after determining the defects existing in the display screen. Since the marking layer corresponds to the display screen, compared with the prior art, it is possible to directly and accurately mark on the marking layer corresponding to the display screen without manually using tools to measure and mark on the display screen, thereby improving the accuracy and efficiency of marking.

The marking symbol module 321 is used to generate a marking symbol for marking the first position based on the user's selection, and the center of the marking symbol coincides with the center of the defect. The annotation module 322 is used to generate an associated information annotation of the marking based on the first position and the marking symbol.
