Please refer to FIG. 2. FIG. 2 is a flowchart of a method for marking defects on a display screen provided by an embodiment of the present application. The method includes:

S110: Create a mark layer corresponding to the size of the display screen, and the mark layer is used to display on the display screen.

Please refer to FIG. 3 , which is a schematic diagram of a markup layer provided by an embodiment of the present application.

In this embodiment, after the user creates the mark layer and does not operate the mark layer, the mark layer can be represented as a colorless and transparent top-level floating window. It can be understood that the top floating window is similar to a colorless transparent film. The top floating window can be displayed on the display. Specifically, the marker layer may be fully transparent (that is, the transparency is 100%) or have a certain transparency (that is, the transparency may be 1%-99%). When the user does not operate the marker layer, the marker layer may be fully transparent. transparent. When the user uses or operates on the marker layer, the marker layer can be displayed as a top-level floating window with a certain transparency, or a top-level floating window with a certain transparency and a background color, so that the user can distinguish the markers Layers and other content displayed. In some implementation cases, when the user operates the marker layer, the marker layer may also be a colorless and transparent top-level floating window with a border of a specific color. It can be understood that the transparency of the marker layer can be adjusted reasonably without affecting the user's detection of defects in the display screen.

In this embodiment, the electronic device may create a marker layer based on the user's control, and the marker layer is used for displaying on the display screen. Among them, when creating a marker layer, the user can set the parameters of the corresponding size according to the size of the display screen, so as to create a marker layer of the corresponding size, so that when the display screen has defects, it can be performed at the corresponding position on the marker layer. mark. Specifically, a marker layer with the same length and width is created according to the length and width of the display screen, so that when the marker layer is displayed on the display screen, each position of the display screen corresponds to each position of the marker layer, thus , when there is a defect on the display screen, marking the corresponding position of the marking layer is equivalent to marking the position of the defect on the display screen.

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, and the detection image is used for displaying on the display screen, so that the user can determine the location of the defects of the display screen based on the detection image, wherein The detection image and the marker layer are displayed overlapping, the marker layer is transparent and has a preset transparency value, and the marker layer is suspended on the detection image.

Usually, inspection images are used when inspecting the display screen for defects. The detection image can be a solid color image of red, yellow, blue, black, and white, or an image of a specific pattern such as a checkerboard. The inspection image is used to display on the display. Since the inspection image has a specific color or pattern, when the inspection image is displayed on the display screen, the defects existing in the display screen can be exposed. For example, when the detection image is a pure white image to detect the display screen, the position of the defect on the display screen may not display white normally, but other colors are displayed, and the user can determine that the position where other colors are displayed on the display screen is the defect position. During detection, the user can also adjust the grayscale of the displayed image through the input device 130, and adjust the grayscale within the range of 0-100, so as to detect the display function of the display screen under different grayscale values. The grayscale can be increased or decreased through the keyboard, and can also be adjusted through the mouse wheel.

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

In this embodiment, the marking layer and the detection image are independent of each other, and the user can operate the marking layer and the detection image respectively. Since the mark layer can be displayed as a fully transparent and colorless layer, when the mark layer can be suspended and displayed on the inspection image, it does not affect the normal display of the inspection image and the user's judgment of defects. Specifically, different colors and patterns need to be detected when detecting the display screen. Since the marking layer is a fully transparent layer, it is possible to avoid the abnormality of the detected image seen by the user due to the color of the marking layer.

In the inspection process, different inspection images need to be used to detect screen defects, so the marking layer and inspection images can be operated separately. It is understandable that during inspection, different inspection images usually need to be displayed on the same display screen. In order to detect different types of display screen defects, the separate operation of the marking layer can also collect the defects existing in the same display screen detected by different inspection images into one layer, which is convenient for saving the defect marking data and checking the existing defects. s position.

S120: Mark a first position on the marking layer based on a user's operation, where the first position is used to represent a corresponding position on the marking layer where the display screen defect is located.

In this embodiment, after the user determines the defect existing in the display screen by detecting the image, the user can mark the corresponding position of the defect position of the display screen on the marking layer. As shown in Figure 4, when the display screen shows that there is an abnormality in the detected image, such as bright lines and bright spots, the user can choose to mark the defect position at the position corresponding to the marking layer.

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

In this embodiment, after the user determines the defect position, the user can use the input device to select the display screen defect at the first position corresponding to the marking layer, select the type of the marking symbol, and create the selected first position on the marking layer. The marker symbol, the electronic device generates the marker symbol at the first position according to the user's selection. Specifically, the pre-set markers are stored in the memory. For example, the markers can be in the form of circle, ellipse, square, etc. The user can select the marker of the desired style, and use the input device to select the location of the defect, and send out the According to the instruction of the selected marker, the electronic device generates the marker of the style selected by the user at the first position according to the received instruction. After creating a marker, the user can select the created marker and make modifications, such as changing the color, size, moving position, etc., such as changing the color of the marker, selecting the marker and dragging it to move the marker , or click the marker, a draggable point will appear on the upper, lower, left, and right sides of the marker. Drag the point to modify the size of the marker.

In this embodiment, when the marker is generated or modified, the center point of the marker will be displayed, and the user can move the center point to the center of the defect, thereby realizing the coincidence of the center of the marker and the center of the defect, thereby making the marker more accurate.

In this embodiment, an association line between the markers can also be set, and the association line is used to represent the relationship between the connected markers. After marking, the marking symbols of the two defects can be connected by an association line to indicate that the two defects belong to the same type of defect. In addition, users can also add annotations, which are used to record defect information or detection-related information, and establish the relationship between markers and annotations through associative lines, so that annotations describe the markers.

In one embodiment, the associated information annotation of the marker is generated based on the first position and the marker symbol.

In this embodiment, after the first location is marked by the marker symbol, the electronic device may generate a corresponding associated information annotation according to the type of the marker symbol and the coordinates of the unique location. As shown in Figure 4, when the marker is an ellipse in the figure, the defect can be judged as a line, and a corresponding annotation can be generated; when the marker is a small circle in the figure, the defect can be judged as a point and a corresponding annotation can be generated. Corresponding annotations can also be generated according to the type of the detection image when marking. For another example, when the detection image is a pure black image, the defects are marked, and the generated annotations can be bright spots or bright lines.

In this embodiment, a complete annotation may include defect information (such as dark spots, bright spots, bright lines, etc.), defect locations, 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 is an example of a display screen defect mark. The content of the associated information mark can be understood as: the types of the two defects are dark spots, and the coordinates of the centers of the two defect positions on the screen are respectively are (13, 9) and (4, 22), the shapes of the marked graphics are all oval C, and (2, 2, B) in the label indicates that the detailed feature is the X-axis length and the Y-axis length of 2, and the marking color is black B, W represent that the detection image used is white.It can be understood that the electronic equipment can generate the labeling information that meets the situation according to the actual situation of the defect.Wherein, the defect position coordinates can take any vertex of the display screen as the origin to establish a coordinate system, The position of the defect center is taken as the coordinates of the defect position.

In this embodiment, after the user confirms that the display screen defects detected by one inspection image are marked, the inspection images can be switched, so that the user can mark the display screen defects detected by other inspection images.

In this embodiment, after the display screen is detected by all the detection images, the electronic device automatically records all the marks and the corresponding label information, and saves the mark layer and the recorded mark labels as a defect record file for the user to view and display information on the screen. In addition, the defect record file can also record the last saved time of the display screen defect mark record, and record the display screen number, two-dimensional code, barcode, serial code and other information, so that the data of each file can be displayed with the display. corresponding to the screen.

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

In one embodiment, after the display screen is detected by using all the inspection images and the defects are saved as a defect record file, the display screen can also be re-judged. The re-judgment process can include: reading the serial number, QR code, barcode, serial code of the display screen and selecting a re-judgment; requesting the server for the defect record file corresponding to the display screen; creating a mark layer and recording the defect information according to the defect information of the file. All markers are drawn on the marker layer and corresponding annotations are generated; since the defect record file records the marker symbols and annotations, and the annotation records the inspection image corresponding to the existing defect, therefore, according to the information of the defect record file, the inspection can be determined. There is an inspection image showing the defect on the display screen, and the inspection image is displayed, so that the user can judge whether there is a defect represented by the mark symbol and label; when the re-judged defect is consistent with the defect detected for the first time, switch to the next If the inspection images are inconsistent, the corresponding marks will be modified; after all the inspection images that have detected defects in the display screen are inspected again, the re-judgment defect record file will be generated; if the re-judgment defect record file and the first detected defect record file If they are inconsistent, upload the re-judgment defect record file to the server for storage.

In this embodiment of the present application, a mark layer corresponding to the size of the display screen is created and displayed on the display screen, so that the user can mark the mark layer after determining the defects existing in the display screen. The layer corresponds to the display screen. Compared with the prior art, it is not necessary to manually use tools to measure and mark the display screen, and directly mark the mark layer corresponding to the display screen accurately, thereby improving the accuracy and efficiency of marking. .
