Problems solved by technology
In the process of actually using the repairing equipment, there is usually a certain deviation between the defect coordinate information transmitted by the upstream equipment and the coordinate system of the repairing equipment. The conventional repair plan is usually only after manual inspection by the operator to find the defects that need to be repaired, which is relatively inefficient. Low, and manual repair is required when repairing, and the accuracy of repairing is low

The invention relates to a panel repair method and device. The method includes: acquiring image information of the panel; converting the image information of the panel into a geometric simulation diagram; and performing a comparison between the converted geometric simulation diagram and a pre-stored geometric simulation diagram. Fitting, detecting the defective area from the transformed geometric simulation diagram; obtaining the offset value between the center of the defective area and the center of the transformed geometric simulation diagram; calculating the defective area according to the offset value Perform position correction. The invention converts the image into a geometric simulation diagram, and performs fitting of the geometric simulation diagram to detect defects, which effectively improves the efficiency of defect detection; after detecting the defect, the offset value is calculated and the defect is detected using the offset value. Patching, improving the accuracy of patching.
Description
technical field [0001] The invention relates to the panel field, in particular to a panel repair method and device. Background technique [0002] Usually, in the production process of the panel, different graphics are usually formed on the panel by using a patterning process. If these graphics have defects, it will cause light leakage or other problems on the panel, thereby affecting the display quality of the panel. To this end, it is necessary to repair the defect pattern. [0003] In the panel industry, using repair equipment to repair defective panel products is an effective way to save product yield. In the process of actually using the repairing equipment, there is usually a certain deviation between the defect coordinate information transmitted by the upstream equipment and the coordinate system of the repairing equipment. The conventional repair plan is usually only after manual inspection by the operator to find the defects that need to be repaired, which is relati...
