Description

Technical Field

[0001] The present application relates to the field of display repair technology, and in particular to a display panel fine circuit repair coating liquid needle adjustment method and related components for repairing fine circuit disconnection defects of a display panel. Background Art

[0002] At present, the fine lines of the display panel, such as the Gate line and the Data line, generally have a line width of 1-50 microns. Due to the process reasons, there will be line break defects. The current repair process is generally to manually adjust the XY axis position of the Ink (coating liquid) needle to ensure that the needle is at the center of the camera, and manually adjust the Z axis height to determine the working distance of the Ink needle in the Z axis direction, and then manually use the camera to observe whether the needle is in the focus position. Within the entire substrate size range, the substrate is array-divided into n line break defect repair areas, and the Ink needle XYZ axis position is further manually compensated and adjusted. After the adjustment is completed, the line break defect repair work begins. However, the current technology has the following disadvantages:

[0003] (1) Manual micron-level precision adjustment is inefficient and low-precision. During the repair process, the accuracy cannot be compensated in real time, which easily leads to quality abnormalities due to low precision in repairing broken wires.

[0004] (2) After the substrate moves over a large range, due to the product flatness problem, it is impossible to ensure that the focus of the ink needle is always on the surface of the substrate;

[0005] (3) In the actual production process, the axis that controls the Ink needle needs to switch positions frequently. After multiple switches, cumulative errors will occur, and the focus position of the Ink needle cannot be guaranteed to be stable, which affects the accuracy of actual circuit repair.

[0068] In one embodiment, Figure 1 As shown, a method for adjusting a display panel fine circuit repair coating needle is provided, comprising the following steps:

[0069] S1: Obtain a reference template for a coating needle for repairing fine circuits of a display panel.

[0070] It should be noted that the display panel fine circuit repair coating needle refers to the Ink needle, which is used to repair the broken wire defects of the display panel fine circuit. The reference template of the display panel fine circuit repair coating needle refers to the template generated based on the Ink needle contour line. The display panel can be an LCD (liquid crystal display) / OLED (current-type organic light-emitting device) panel, and the display panel fine circuit can be the Gate line, Data line, etc. on the LCD / OLED panel.

[0071] In some specific embodiments, Figure 2 As shown, before obtaining the reference template of the coating needle for repairing fine circuits of the display panel, the method also includes:

[0072] Detecting whether there is a reference template of a display panel fine circuit repair coating needle, wherein the reference template of the display panel fine circuit repair coating needle pre-stored in the database can be matched by an identifier of the display panel fine circuit repair coating needle, and the identifier can be information such as the display panel fine circuit repair coating needle model;

[0073] In response to the non-existence, constructing a reference template of the display panel fine circuit repair coating needle, that is, when the identifier of the display panel fine circuit repair coating needle does not exist in the database, it is determined that the reference template of the display panel fine circuit repair coating needle does not exist in the database, and at this time, it is necessary to construct a reference template corresponding to the display panel fine circuit repair coating needle;

[0074] In response to the existence, a reference template of the display panel fine circuit repair coating needle is obtained, that is, when the identifier of the display panel fine circuit repair coating needle exists in the database, it is determined that the reference template of the display panel fine circuit repair coating needle exists in the database, and the reference template corresponding to the display panel fine circuit repair coating needle can be directly obtained.

[0075] In some specific embodiments, constructing a reference template for a display panel fine circuit repair coating needle includes:

[0076] Adjust the Z-axis coordinate position of the display panel fine circuit repair coating needle until the display panel fine circuit repair coating needle is in the focus position of the camera device. After the display panel fine circuit repair coating needle is installed, the Z-axis coordinate position of the display panel fine circuit repair coating needle can be adjusted by Jog (manually) so that the display panel fine circuit repair coating needle is in the focus position of the camera device. At this time, a clear image of the display panel fine circuit repair coating needle can be presented;

[0077] In response to the display panel fine circuit repair coating needle being at the focus position of the camera device, adjusting the X-axis and Y-axis coordinate positions of the display panel fine circuit repair coating needle until the display panel fine circuit repair coating needle is at the center position of the camera device. In this step, the Z-axis coordinate position of the display panel fine circuit repair coating needle remains unchanged, and only the X-axis and Y-axis positions of the display panel fine circuit repair coating needle are moved until the display panel fine circuit repair coating needle is at the center position of the camera device;

[0078] Acquire an image of a display panel fine circuit repair coating needle at a current position, and extract the contour of the display panel fine circuit repair coating needle based on preset template parameters. Specifically, adjust the size of the display panel fine circuit repair coating needle template image rectangle parameters, automatically calculate and determine the template area according to the image rectangle parameters, and intercept the image of the display panel fine circuit repair coating needle in the current area. Further, according to the preset template parameters, extract the contour of the display panel fine circuit repair coating needle. The template parameters may include pyramid level, starting angle, optimization value and contrast, and the specific values ​​can be set according to actual needs.

[0079] The contour line of the display panel fine circuit repair coating needle is defined as the reference template of the display panel fine circuit repair coating needle, and the corresponding position information of the display panel fine circuit repair coating needle is defined as the reference template information, that is, the contour line obtained in the above steps is saved as the reference template of the display panel fine circuit repair coating needle, and the current XYZ axis position information of the display panel fine circuit repair coating needle, that is, the XYZ axis coordinate information, is recorded at the same time, and the XYZ axis position information is saved as the reference template information, and the reference template and its corresponding reference template information are saved in the database.

[0080] S2: moving the display panel fine circuit repair coating needle to a first target position, and acquiring a plurality of display panel fine circuit repair coating needle images within a moving range of the display panel fine circuit repair coating needle corresponding to a preset position at the first target position.

[0081] It should be noted that the first target position refers to any position on the surface of the product. The product may refer to an LCD (liquid crystal display) / OLED (current-type organic light-emitting device) panel, etc. The preset position moving range can be set according to actual needs, such as ±5mm up and down along the Z-axis direction. The first target position corresponding to the preset position moving range refers to the range of ±5mm up and down along the Z-axis direction of the first target position. If the first target position is (X, Y, Z), the coordinate range determined based on the first target position corresponding to the preset position moving range is (X, Y, Z±5mm).

[0082] In some specific embodiments, moving a display panel fine circuit repair coating needle to a first target position, and acquiring a plurality of display panel fine circuit repair coating needle images within a moving range of the display panel fine circuit repair coating needle corresponding to a preset position at the first target position includes:

[0083] In response to the display panel fine circuit repair coating needle head having moved to the first target position, obtaining the position movement range of the display panel fine circuit repair coating needle head in the Z-axis direction;

[0084] According to the preset number of position movement and the position movement spacing, the display panel fine circuit repair coating needle is moved within the position movement range, and the display panel fine circuit repair coating needle image after each movement is obtained, and multiple display panel fine circuit repair coating needle images are obtained, wherein the preset number of position movement and the position movement spacing can be set according to actual needs. For example, when the preset position movement range is ±5mm, the preset number of position movement is 5 times, and the position movement spacing can be equal distance, such as 2mm each time, or it can be random movement, such as 1mm for the first movement, 3mm for the second movement, 2mm for the third movement, etc. The position movement spacing can be selected according to actual needs, and the display panel fine circuit repair coating needle image can be obtained. After each movement of the panel fine circuit repair coating needle, an image of the display panel fine circuit repair coating needle at that position is obtained. When the preset number of movements is reached, multiple display panel fine circuit repair coating needle images can be obtained, and the position information of the display panel fine circuit repair coating needle in each display panel fine circuit repair coating needle image is recorded. Exemplarily, the display panel fine circuit repair coating needle is moved to any position of the product, and 5 display panel fine circuit repair coating needle images are taken within the range of ±5mm above and below with the Z-axis focal position as the center, and the position information of the display panel fine circuit repair coating needle in each display panel fine circuit repair coating needle image is recorded.

[0085] S3: Matching the plurality of display panel fine circuit repair coating needle images with a reference template of the display panel fine circuit repair coating needle, and determining a target display panel fine circuit repair coating needle image according to the matching result.

[0086] It should be noted that this step can calculate the similarity between the display panel fine circuit repair coating needle outline in the display panel fine circuit repair coating needle image and the reference template through a shape matching algorithm. The shape matching algorithm is a commonly used method in the field of computer vision technology, and its specific calculation process will not be repeated here.

[0088] Based on the shape matching mechanism, multiple display panel fine circuit repair coating needle images are matched with the reference template of the display panel fine circuit repair coating needle one by one to obtain multiple matching scores, that is, the contour line of the display panel fine circuit repair coating needle in each display panel fine circuit repair coating needle image is extracted, and the similarity of the contour line and the reference template is calculated, and the calculation result is the matching score, wherein the larger the matching score, the clearer the display panel fine circuit repair coating needle image is;

[0089] Sort multiple matching scores, and select a target display panel fine circuit repair coating needle image based on the sorting results, wherein the matching scores can be sorted from large to small or from small to large, and the image with the largest matching score in the sorting results is selected as the target display panel fine circuit repair coating needle image.

[0090] S4: Determine the position deviation value of the display panel fine circuit repair coating needle based on the target display panel fine circuit repair coating needle image and the reference template of the display panel fine circuit repair coating needle.

[0091] It should be noted that the position deviation value of the display panel fine circuit repair coating needle is the difference between the coordinate value corresponding to the target display panel fine circuit repair coating needle image and the coordinate value corresponding to the reference template. The above coordinate value generally refers to the needle tip coordinate value.

[0092] In some specific embodiments, based on the target display panel fine circuit repair coating needle image and the reference template of the display panel fine circuit repair coating needle, determining the position deviation value of the display panel fine circuit repair coating needle includes:

[0093] Obtaining the position information of the display panel fine circuit repair coating liquid needle in the target display panel fine circuit repair coating liquid needle image and the reference template information, wherein the position information of the display panel fine circuit repair coating liquid needle in the target display panel fine circuit repair coating liquid needle image is the coordinate value corresponding to the target display panel fine circuit repair coating liquid needle image, and the reference template information is the coordinate value corresponding to the reference template;

[0094] Calculate the difference between the position information of the display panel fine circuit repair coating needle in the target display panel fine circuit repair coating needle image and the reference template information, and define the difference as the position deviation value of the display panel fine circuit repair coating needle, that is, subtract the position information of the display panel fine circuit repair coating needle in the target display panel fine circuit repair coating needle image from the reference template information to obtain the corresponding difference.

[0095] S5: adjusting the position of the display panel fine circuit repair coating needle that has moved to the second target position based on the position deviation value of the display panel fine circuit repair coating needle.

[0096] It should be noted that the second target position refers to any position of the broken wire to be repaired on the product, such as the defective position of the Source line (output line of the signal source) and the Com line (fire line) on the panel ITO (conductive glass) and the GATE layer (gate layer in the integrated circuit).

[0097] In some specific embodiments, adjusting the position of the display panel fine circuit repair coating needle that has moved to the second target position based on the position deviation value of the display panel fine circuit repair coating needle includes:

[0098] In response to receiving a display panel fine line disconnection defect repair request, moving the display panel fine line repair coating liquid needle to a second target position;

[0099] According to the position deviation value of the display panel fine circuit repair coating liquid needle head, the position of the display panel fine circuit repair coating liquid needle head that has moved to the second target position is adjusted, that is, the position of the display panel fine circuit repair coating liquid needle head that has moved to the second target position is compensated and corrected by the position deviation value of the display panel fine circuit repair coating liquid needle head, so as to obtain the corrected display panel fine circuit repair coating liquid needle head position;

[0100] In response to the completion of the adjustment, a display panel fine circuit broken line defect repair operation is performed, that is, after the display panel fine circuit repair coating needle position correction is completed, the display panel fine circuit repair coating needle performs a coating repair operation according to the position corresponding to the Ink repair line shape to respond to the display panel fine circuit broken line defect repair request.

[0101] In the above-mentioned display panel fine circuit repair coating liquid needle adjustment method, the method includes: obtaining a reference template of the display panel fine circuit repair coating liquid needle; moving the display panel fine circuit repair coating liquid needle to a first target position, and obtaining a plurality of display panel fine circuit repair coating liquid needle images within a movement range of a preset position corresponding to the first target position of the display panel fine circuit repair coating liquid needle; matching the plurality of display panel fine circuit repair coating liquid needle images with the reference template of the display panel fine circuit repair coating liquid needle, and determining a target display panel fine circuit repair coating liquid needle image based on the matching result; and adjusting the display panel fine circuit repair coating liquid needle image based on the target display panel fine circuit repair coating liquid needle image and the display panel fine circuit repair coating liquid needle image. The reference template of the coating liquid needle is used to determine the position deviation value of the coating liquid needle for repairing fine circuits of the display panel; based on the position deviation value of the coating liquid needle for repairing fine circuits of the display panel, the position of the coating liquid needle for repairing fine circuits of the display panel that has been moved to the second target position is adjusted. Compared with the existing manual adjustment of the position of the coating liquid needle for repairing fine circuits of the display panel, the present application improves the adjustment efficiency of the coating liquid needle for repairing fine circuits of the display panel by automatically adjusting the position of the coating liquid needle for repairing fine circuits of the display panel, corrects the position of the coating liquid needle for repairing fine circuits of the display panel by the position deviation value, improves the adjustment accuracy of the coating liquid needle for repairing fine circuits of the display panel, and thus improves the accuracy and efficiency of broken line repair.
