Nt61219hc6021a Cof Datasheet Exclusive May 2026
This occurs when the output bonding pad (Pin 78 to 144, depending on the segment) detaches from the glass.
The NT61219HC6021A is ideal for systems requiring:
Look for traces leading from the main input connector (the flex that goes to the motherboard) to the chip.
Would you like help identifying the LCD panel model that might use this COF, or a strategy to contact Novatek’s support for an old datasheet request?
The NT61219HC6021A is a specialized Chip-On-Film (COF) integrated circuit primarily used as a Source Driver for high-resolution LCD and LED display panels. This component is part of the Novatek (NT) series, often found in repair contexts for large-format televisions and monitors where thin-film bonding is required to bridge the glass panel and the PCB. Long Feature: Advanced Multi-Channel Source Driving nt61219hc6021a cof datasheet exclusive
The standout feature of the NT61219HC6021A is its High-Density Channel Output with Integrated Low-Power Management. Unlike standard drivers, this COF package is engineered to handle the massive data throughput required for 4K and Ultra-HD resolutions while maintaining structural flexibility.
Chip-On-Film (COF) Architecture: This technology mechanically fixes the semiconductor chip onto a flexible film. It is specifically designed to tolerate extreme temperatures (often exceeding 400∘C400 raised to the composed with power C ) during the Inner Lead Bonding (ILB) process.
Structural Flexing & Space Efficiency: The film is thin enough to permit flexing at any point, which is crucial for modern "borderless" or "narrow-frame" display designs. This allows the driver to be folded behind the panel, significantly reducing the width of the display bezel.
Thermal Stability: Despite the high electrical load of driving hundreds of individual source lines, the NT61219 series uses a high-conductivity substrate that minimizes dimensional change during the bonding process. This occurs when the output bonding pad (Pin
Precision Voltage Control: It employs sophisticated digital-to-analog converters (DACs) to provide precise gamma-corrected voltages to each pixel, ensuring high color accuracy and smooth gradients across the display. Common Use Cases:
LCD/LED Panel Repair: Often used in bonding machines for fixing "vertical line" issues on television screens.
UHD Display Manufacturing: Ideal for high-refresh-rate panels where signal integrity over flexible leads is paramount.

Title: Technical Assessment of the NT61219HC6021A Chip-on-Film (COF) Package Subject: NT61219HC6021A COF Datasheet Exclusive Date: October 26, 2023 Prepared For: Display Engineering & Procurement Teams
If you are looking for this datasheet to repair a panel (e.g., vertical lines on screen), you don't need the full specs, just the diagnostic logic.
The "A" revision has a known thermal coefficient issue. At ambient > 70°C, quiescent current jumps from 5 mA to 50 mA, causing the COF to delaminate from the glass.
Why is the keyword "exclusive" attached to this datasheet? Because LG Display has moved to a closed-loop supply chain. Look for traces leading from the main input
You cannot buy a genuine NT61219HC6021A from Mouser, DigiKey, or Alibaba with standard lead times. The IC is programmed with a unique T-Con Handshake Code.
