Nt61219h-c6021a Cof: Datasheet
The NT61219H-C6021A is a source driver IC packaged in a COF (Chip-on-Film) format. It bonds directly to the flexible printed circuit (FPC) that connects the LCD glass to the main control board.
T-Con Board (Timing Controller) -> Mini-LVDS Cable -> PCB (X-board) -> NT61219H-C6021A COF -> LCD Glass Columns
The COF receives serialized video data, deserializes it via a shift register, latches one horizontal line, applies gamma correction (via internal resistor ladder or external references), and drives the pixel capacitors at high voltage.
One of the standout features in the NT61219H series datasheet is the integrated power management logic:
A: You need a pulse heat bonding machine (ACF bonder), a microscope for alignment, and ACF tape (width matching the 35µm pitch). Manual soldering is impossible due to the fine pitch. nt61219h-c6021a cof datasheet
Below is a blog post written assuming NT61219H-C6021A is a source driver COF for high-resolution LCD displays.
The NT61219H-C6021A features a complex pinout. Below is a logical grouping of signals (Note: Consult a physical datasheet for exact pad locations, as they vary by manufacturer).
| 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). | The NT61219H-C6021A is a source driver IC packaged
COF components are vulnerable during handling due to exposed copper leads.
| Model | Specification | Level | | :--- | :--- | :--- | | HBM (Human Body Model) | ±4kV | Class 3A | | CDM (Charged Device Model) | ±1kV | Class C3 | | MM (Machine Model) | ±200V | Class B |
Handling Recommendation: Use conductive anti-static trays and grounded wrist straps. Do not bend the COF within 2mm of the IC edge. The COF receives serialized video data, deserializes it
The NT61219H-C6021A is a proprietary Source Driver Chip-on-Film designed for large-format TFT-LCD panels. The naming convention reveals critical information:
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.
