Description

Technical Field

[0001] The present application relates to the field of display repair technology, and in particular to a method and component for adjusting a display panel fine circuit repair path. Background Art

[0002] The current display panel fine lines such as Gate lines and Data lines generally have a line width of 1-50 microns. Due to process reasons, there will be broken line defects. The current repair process is generally based on the drawn repair path. The broken line defects are repaired by using the Ink (liquid coating) needle under the Ink camera. After the repair is completed, the Ns (nanosecond) laser is used for baking and curing. After the baking and curing are completed, it is necessary to switch to the AF (Automatic Focus) camera and use the Fs (femtosecond) laser to trim the edge width of the curing path. During the multiple switching between the AF camera and the Ink camera, due to external factors such as equipment vibration, product flatness, and axis movement accuracy, the stability of the Ink needle's liquid coating trajectory cannot be guaranteed, resulting in an offset of the liquid coating trajectory compared to the repair path. When the liquid coating trajectory is offset, when it is moved from the Ink camera to the AF camera again for laser trimming, there will be multiple accumulated precision errors, resulting in the Fs laser trimming accuracy exceeding 3 microns, which cannot meet the performance requirements.

[0073] In one embodiment, Figure 1-Figure 2 As shown, a method for adjusting a display panel fine line repair path is provided, comprising the following steps:

[0074] S1: drawing an initial repair path according to the disconnection defect of the fine circuit of the display panel, and acquiring a first image corresponding to the initial repair path by using a first camera.

[0075] It should be noted that the display panel may include an LCD (liquid crystal display) / OLED (current-type organic light-emitting device) panel, etc., and the fine circuits of the display panel may include Gate lines, Data lines, etc.

[0076] In some specific embodiments, before drawing an initial repair path according to the disconnection defect of the fine circuit of the display panel and acquiring a first image corresponding to the initial repair path by using a first camera, the method further includes:

[0077] Acquire a first center position of the first camera and a second center position of the second camera respectively;

[0078] Determining a direction deviation value between the first camera and the second camera based on the first center position and the second center position;

[0079] Based on the direction deviation value, a moving direction and distance for switching the gantry corresponding to the first camera and the second camera are determined.

[0080] Among them, the first camera is an Ink camera, and the second camera is an AF camera. The current working camera is switched by moving the gantry. For example, if the gantry moves under the Ink camera, the image information in the display panel can be captured by the Ink camera. If the gantry moves under the AF camera, the image information in the display panel can be captured by the AF camera. The moving distance and direction are determined by the center position difference between the two cameras. The coordinate difference between the center position of the AF camera and the center position of the Ink camera in the XY axis direction is calibrated as the XY axis direction deviation values ​​OffsetX1 and OffsetY1, and the Z axis direction coordinate value remains unchanged. Based on this, the gantry is moved to switch the first camera and the second camera.

[0081] In some specific embodiments, when a short circuit defect is detected in a fine circuit of a display panel, the coordinate position of the short circuit defect is obtained, and based on the coordinate position, an initial repair path is drawn under the AF camera. After the drawing is completed, the gantry is moved to the Ink camera according to OffsetX1 and OffsetY1, and the first image corresponding to the initial repair path is captured.

[0082] S2: Based on the initial repair path, the open circuit defects of the fine circuits of the display panel are repaired and baked to be cured, a curing path is generated, and a second image of the curing path is acquired by using a first camera.

[0083] It should be noted that the repair coating material for the short-circuit defects of the fine circuits of the display panel is Ag or PTC (conductive material), etc. According to the initial repair path drawn, the short-circuit defects of the fine circuits of the display panel are repaired by coating with the Ink needle under the Ink camera, and the repair coating is baked and cured using an Ns (nanosecond) laser. After baking and curing, the second image of the curing path is obtained through the Ink camera.

[0084] S3: Extracting a first contour of the curing path based on the path grayscale values ​​of the first image and the second image.

[0085] It should be noted that the image grayscale value refers to the color depth of each pixel in a black and white image, usually ranging from 0 to 255, where 0 represents black and 255 represents white. The larger the grayscale value, the brighter the pixel, and the smaller the grayscale value, the darker the pixel.

[0086] In some specific embodiments, extracting a first contour of the curing path based on the path grayscale values ​​of the first image and the second image includes:

[0087] Grayscale processing is performed on the first image and the second image, wherein the grayscale processing refers to the process of converting the first image and the second image from color images to grayscale images, and the specific process is to make the three component values ​​of R, G, and B of the color image equal (that is, R=G=B), so as to convert the color image into a grayscale image. The specific conversion method includes a component method, a maximum value method, an average value method, a weighted average method, etc., which can be selected according to actual needs. The conversion method is a commonly used method and will not be repeated here. By grayscale processing the first image and the second image, the efficiency of subsequent image processing can be improved;

[0088] Based on the filtering algorithm, filtering is performed on the grayscaled first image and the second image respectively, and the path grayscale value of the first image is determined, wherein the filtering operation is to suppress the noise of the target image while retaining the image detail features as much as possible. Based on this, the step removes the image noise in the first image and the second image through the filtering algorithm. The filtering algorithm may include a limiting filtering method, a median filtering method, and an arithmetic mean filtering method, etc., which can be selected according to actual needs. Filtering the image through the above filtering algorithm is a common method, and the specific process of filtering is not repeated here;

[0089] Based on the contrast enhancement algorithm, gray enhancement processing is performed on the second image after graying, and the path gray value of the second image is determined, wherein the contrast enhancement algorithm is used to expand the range between the gray levels of the image to improve the accuracy of contour extraction. The contrast enhancement algorithm includes a linear enhancement method, a nonlinear enhancement method, and a histogram enhancement method, etc., which can be selected according to actual needs. It is a common method to perform image enhancement processing on the image by using the above contrast enhancement algorithm, and the specific process of image enhancement processing will not be repeated here;

[0090] Calculate the path grayscale difference between the path grayscale value of the first image and the path grayscale value of the second image, and extract the first contour of the curing path based on the path grayscale difference, wherein the path grayscale difference here is an absolute value. The first contour of the curing path can be extracted based on the calculated absolute grayscale difference between the first image and the second image.

[0091] In some specific embodiments, after extracting the first contour of the solidification path based on the path grayscale values ​​of the first image and the second image, the method further includes:

[0092] Obtaining a first center coordinate position of the first contour in the second image and a second center coordinate position of the second image, wherein the first center coordinate position is the position of the center of the contour in the second image, and the second center coordinate position is the center position of the second image, and the first center coordinate position and the second center coordinate position may only include coordinates in the XY axis direction;

[0093] Calculate a first position deviation value between the first center coordinate position and the second center coordinate position, wherein the first position deviation value is an absolute difference value, and its calculation formula may be OffsetX2=|X2-X1|, OffsetY2=|Y2-Y1|, the first position deviation value is OffsetX2, OffsetY2, (X1, Y1) represents the first center coordinate position, (X2, Y2) represents the second center coordinate position;

[0094] In response to the first position deviation value being within the first preset range, the gantry is moved from the first camera to the second camera according to the direction deviation value between the first camera and the second camera, so as to obtain a third image of the curing path based on the second camera, wherein the first preset range can be set according to actual needs, and a generally smaller value is set, such as when the first position deviation value is less than a preset value, so as to screen out a second image with a smaller error, and when the first position deviation value is within the first preset range, the gantry is moved from the first camera to the second camera according to the direction deviation value, so as to obtain a third image of the curing path based on the second camera;

[0095] In response to the first position deviation value not being within the first preset range, the repair path is redrawn and the first position deviation value calculation operation is performed until the first position deviation value is within the first preset range, that is, when the first position deviation value is not within the first preset range, the above steps are repeated until the first position deviation value is within the first preset range.

[0096] S4: acquiring a third image of the curing path based on the second camera, and determining a second contour of the curing path in the third image according to the first contour of the curing path.

[0097] It should be noted that the third image is an image captured by the AF camera when the gantry is moved under the AF camera.

[0098] In some specific embodiments, determining a second contour of the curing path in the third image according to the first contour of the curing path includes:

[0099] gray-scaling the third image;

[0100] Based on a filtering algorithm, filtering is performed on the third image after the grayscale processing;

[0101] Based on the contrast enhancement algorithm, grayscale enhancement processing is performed on the third image after the filtering processing, and the second contour of the solidification path in the third image after the grayscale enhancement processing is determined based on the first contour matching of the solidification path.

[0102] Specifically, the above-mentioned grayscale processing method, filtering algorithm and contrast enhancement algorithm are the same as the method in step S3 and will not be repeated here. The first contour of the solidification path is defined as a contour template, and the contour template is matched with the processed third image to obtain the second contour of the solidification path in the third image and the position information of the second contour.

[0103] S5: Determine a contour accuracy deviation value based on the center coordinate positions of the first contour and the second contour.

[0104] It should be noted that the center coordinate position of the first contour refers to the position of the center of the first contour in the second image, and the center coordinate position of the second contour refers to the position of the center of the second contour in the third image.

[0105] In some specific implementations, determining the contour accuracy deviation value based on the center coordinate positions of the first contour and the second contour includes:

[0106] Acquire a first center coordinate position of the first contour in the second image and a third center coordinate position of the second contour in the third image;

[0107] Calculate a second position deviation value between the first center coordinate position and the third center coordinate position, wherein the second position deviation value is calculated as OffsetX3=X3-X1, OffsetY3=Y3-Y1, wherein OffsetX3, OffsetY3 represent the second position deviation value, (X3, Y3) represents the third center coordinate position, and (X1, Y1) represents the first center coordinate position;

[0108] In response to the second position deviation value being within the second preset range, defining the second position deviation value as a contour accuracy deviation value, wherein the second preset range can be set according to actual needs, and a generally smaller value is set, such as the second position deviation value being less than a preset value, so as to screen out a second contour with a smaller error, thereby improving the accuracy of contour accuracy deviation value calculation;

[0109] In response to the second position deviation value not being within the second preset range, the repair path is redrawn and the second position deviation value calculation operation is performed until the second position deviation value is within the second preset range. If the second position deviation value exceeds a preset value, the above steps are re-executed until the second position deviation value is less than a preset value.

[0110] S6: According to the contour accuracy deviation value, the second contour position of the solidification path in the third image is adjusted to obtain a target repair path.

[0111] It should be noted that this step is an operation performed when the gantry moves to the AF camera, that is, OffsetX3 and OffsetY3 are compensated to the center coordinate position of the second contour. After compensating the contour accuracy deviation value to the center coordinate of the laser repair path, the target repair path can be obtained. After obtaining the target repair path, the method further includes:

[0112] The edge width of the target repair path is adjusted, and in response to the completion of the adjustment, it is determined that the open circuit defect repair operation of the display panel fine circuit is completed, that is, the contour edge is trimmed using the Fs laser to remove excess coating liquid from the contour edge, so that the trimmed contour width accuracy is within the range of 3um to meet the repair process requirements.

[0113] In the above-mentioned display panel fine circuit repair path adjustment method, the method includes: according to the open circuit defect of the display panel fine circuit, drawing an initial repair path, using a first camera to obtain a first image corresponding to the initial repair path; based on the initial repair path, the open circuit defect of the display panel fine circuit is repaired and baked and cured to generate a curing path, and the second image of the curing path is obtained by the first camera; based on the path grayscale values ​​of the first image and the second image, a first contour of the curing path is extracted; based on the second camera, a third image of the curing path is obtained, and according to the first contour of the curing path, a second contour of the curing path in the third image is determined; based on the central coordinate position of the first contour and the second contour, a contour accuracy deviation value is determined; according to the contour accuracy deviation value, the second contour position of the curing path in the third image is adjusted to obtain a target repair path; the present application obtains image information under the AF camera and the Ink camera in real time, analyzes the position deviation of the path contour, so as to determine the contour accuracy deviation value, and dynamically compensates the path contour position in the image based on the contour accuracy deviation value, thereby overcoming the problem of affecting the repair accuracy due to camera switching, lens switching, dynamic deviation of the coating accuracy of the repair path, and the inability to adjust static parameters in real time, thereby improving the repair accuracy of the open circuit defect.

[0114] It should be understood that although Figure 1-Figure 2 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 1-Figure 2 At least part of the steps may include multiple sub-steps or multiple stages.
