The datasheet reveals a hidden "Test Mode" (Pin 99 tied to VGH through a 100k resistor). This allows you to test the COF without a T-Con board, forcing all outputs to a 50% gray pattern. This is the only way to diagnose if the COF or the panel glass is shorted. Conclusion: Why This Document is Your Golden Ticket The NT61219HC6021A COF Datasheet is more than a technical document; it is the key to extending the life of millions of LG-based 4K televisions. As manufacturers push for "non-repairable" bonded displays, having the exclusive electrical specs, pinouts, and timing diagrams for this component puts you ahead of 99% of repair shops.
This article serves as an for the NT61219HC6021A COF Datasheet . We will break down its technical parameters, application logic, common failure modes, and why sourcing this exact Chip on Film (COF) component is becoming a bottleneck in the display repair industry. What is the NT61219HC6021A? Defining the Component Before diving into the datasheet, we must understand the architecture. NT61219HC6021A is not a standard IC; it is a Driver IC bonded to a flexible film —commonly known in the industry as a Chip on Film (COF) or TCP (Tape Carrier Package).
Always cross-reference the "Lot Number" on the physical COF film (located near the sprocket hole) with the "Wafer Fab Code" in the datasheet's appendix. If the codes don't match the revision table, you are likely holding a counterfeit part. nt61219hc6021a cof datasheet exclusive

In the high-stakes world of modern electronics, the difference between a flagship display and a failed prototype often comes down to a single, overlooked component. For engineers, procurement specialists, and repair technicians working on large-format LCD panels, one number has recently surfaced as a critical reference: NT61219HC6021A . The datasheet reveals a hidden "Test Mode" (Pin
The specifications listed above are aggregated from field repairs and service manuals. Always refer to the official LG Display restricted datasheet for exact voltage and timing tolerances for your specific panel revision.

Note the tight tolerance on AVDD (14.0V typ). If your power management IC (PMIC) supplies 15.2V, the NT61219HC6021A will overheat, crack the chip, and short the column lines, resulting in a vertical line defect on the screen. Application: Which TV Models Use This COF? If you are searching for this datasheet, you likely have a broken TV on your bench. This COF is exclusively found in Ultra High Definition (UHD) 4K and 8K panels produced between 2018 and 2024. Conclusion: Why This Document is Your Golden Ticket
Section 6.2 details the "Source Output Delay." When using a SONY CX7 bonding machine, you must set the "Thermode Temperature" to exactly 270°C ± 5°C for exactly 8 seconds. Too hot, and the "HC" polymer film melts; too cold, and the ACF does not cure.
