Technicians often use "flying line" or when a specific trace on the original COF is damaged. These diagrams map the internal pinouts to allow for manual wiring (jumpers) to restore signal flow without replacing the entire module. Sourcing and Availability

The NT61219H-C6021A is a Chip-On-Film (COF) driver module used in LCD/TFT display assemblies to drive panel gate and source lines while minimizing board area and simplifying display integration. COF packages like this combine fine-pitch driver ICs with a flexible film substrate for direct attachment to glass panels, enabling thinner bezels and compact device profiles.
