The NT61219H-C6021A is a high-performance Timing Controller (T-Con) COF package designed by Note Technology (Note Electronic). It is engineered for Large-Sized LCD Panels, typically found in 4K High-Resolution TVs (ranging from 43" to 65"+).
That said, I can help you in two ways:
If you are troubleshooting a display issue (like vertical lines or a "no picture" condition), technicians often look for: nt61219h-c6021a cof datasheet
| Pin Group | Signal Name | Description | | :--- | :--- | :--- | | Input Power | VDD, VSS | Digital core power (3.3V) and ground. | | | AVDD, AVSS | Analog power for output buffers (13-17V). | | | VGH, VGL | Gate high (25-30V) and Gate low (-5V to -8V) – passed through for gate drivers. | | Data Input | RxIN0P/N ... RxIN9P/N | 10-pair Mini-LVDS differential data lines. | | | RxCLKINP/N | Differential clock input. | | Control | POL | Polarity inversion signal (line or dot inversion). | | | STH (Start Horizontal) | Horizontal start pulse for source driver shift register. | | | CPH (Clock Horizontal) | Clock for shifting in data. | | Output | S1 to S720 | Analog source drive outputs to LCD columns. | | Test | TEST1, TEST2 | Factory test pins (leave floating in application). |
To prevent latch-up and panel flicker, follow this exact sequence: | | | AVDD, AVSS | Analog power for output buffers (13-17V)
VGH (Voltage Gate High): The power that switches pixels "on". VGL (Voltage Gate Low): The pulse that shuts them "off".
This COF is predominantly used in 4K UHD (3840x2160) and 8K televisions, medical monitors, and high-end industrial displays. It is responsible for converting the mini-LVDS or eDP (Embedded DisplayPort) input signals into the analog voltages required to drive each column of pixels.

Hidden behind the bezel, Elias found the NT61219H-C6021A. This COF is essentially a flexible ribbon cable with a silicon brain embedded directly onto the film. Its datasheet is the "holy grail" for technicians like Elias; it doesn't just list voltage—it provides the map for every signal, from the gate drivers to the source clocks.
