Reference PDF of about 39.2 MB on COF and TAB flying line figures attributed to deybynet, related to an LCD TV repair machine. COF and TAB are the flexible driver bonds that join the panel glass to source and gate drivers, and flying line repair means bridging broken traces with fine wire. The figures show where to place jumpers for line faults on many panels. Match your panel model and flex layout to the figure exactly before soldering, as a wrong bridge can damage the driver.
