Search for the panel model number (sticker on the back of the screen) instead of the COF IC number. The panel’s datasheet often lists electrical characteristics of its COF drivers.
Before diving into the specifics of the NT61219HC6021A, it's essential to understand what COF technology entails. COF, or Chip-on-Film, is a packaging technology used in displays, where the driver IC (Integrated Circuit) is mounted directly onto a flexible film. This approach allows for thinner, lighter, and more flexible display designs compared to traditional packaging methods.
The NT61219HC6021A COF is a powerful yet enigmatic component. Its "exclusive" nature means standard datasheets are hidden behind OEM NDAs, but the technical data provided here—from power sequencing to failure analysis—gives any display engineer or repair technician the upper hand.

NT61219HC6021A COF Datasheet: The Definitive Guide for Panel Repair
Are you struggling with a "No Picture" or "Vertical Line" issue on a modern LED/LCD TV? If the panel uses the NT61219HC6021A COF (Chip-on-Film)
, you’ve likely found that technical documentation is incredibly hard to come by.
In this exclusive deep dive, we break down what makes this driver IC tick and where you can find the vital pinout data needed for successful ACF bonding and bypass repairs. What is the NT61219HC6021A? The NT61219HC6021A
is a Display Driver IC manufactured by Novatek Microelectronics. It is mounted on a flexible film ribbon cable (COF) that connects the T-Con board (or Source PCB) to the LCD glass.
Its primary job is to receive high-speed signals and translate them into precise voltages that control the liquid crystal pixels. When this chip fails—often due to heat or liquid damage—it results in the common "flickering" or "line" symptoms seen in professional TV repair. Key Specifications (Technical Overview)
While the full factory datasheet is often protected under NDA, repair technicians have identified these core characteristics for the NT61-series COFs:
Technology: CMOS silicon gate process for low power consumption.
Function: Integrated Source/Gate driver logic for high-resolution panels.
Voltage Requirements: Typically requires VGH (Gate High), VGL (Gate Low), and VDD (Logic) supplies to function.
Interface: High-speed differential signaling (similar to LVDS or mini-LVDS). Troubleshooting with the NT61219HC6021A
If you are performing a COF Bypass (Flying Line) repair, you need to identify the "Gate Points" on the film. Common failure points include: nt61219hc6021a cof datasheet exclusive
VGH/VGL Missing: Often causes a slow-motion or ghosting image.
STVP/CPV Signals: Critical for timing; if these are broken, the screen may remain completely blank.
Burn Marks: Physical inspection under a microscope often reveals "pitting" or carbonization on the NT61219HC6021A chip itself. Exclusive: Where to Download the Datasheet
Because these are industrial components, you won't find them on standard consumer sites. However, technical repositories often host "COF Data Books" that include the NT61219HC6021A:
Scribd Technical Archives: Detailed lists of COF equivalents and pinouts can be found on Scribd's COF IC Data Sheets.
Repair Communities: Platforms like Pinterest's Gate COF Data boards often host leaked "flying line" diagrams specifically for the NT series.
Technical Video Guides: For a visual walkthrough of pin measurements, the Electro Burner YouTube channel is a known resource for COF troubleshooting. Final Thoughts for Technicians Replacing an NT61219HC6021A
requires professional ACF bonding equipment. Attempting a manual solder repair on these pins is nearly impossible due to the microscopic pitch. Always verify your VGH/VGL voltages at the T-Con first before blaming the COF!

The NT61219HC6021A is a specialized Chip-on-Film (COF) driver IC, typically manufactured by Novatek, primarily used in the manufacturing and repair of large-format LCD and LED television panels.
While technical datasheets for specific COF part numbers are often proprietary to panel manufacturers (like Samsung or LG) and repair professionals, the NT61219 series generally features: Primary Features
Driver Type: Source driver IC integrated onto a flexible film.
Application: High-definition (HD) and Ultra-HD (4K) LCD/LED display panels.
Mounting Technology: TCP (Tape Carrier Package) or COF, which allows for the slim bezel designs found in modern TVs. Function: TFT-LCD Source Driver (Column Driver)
High Pin Density: Designed to handle a high number of output channels to drive thousands of vertical columns of pixels on a screen. Typical COF Specifications
While the exact "6021A" variant details are exclusive, similar Novatek NT61xxx series drivers typically offer:
Voltage Support: Compatibility with standard panel logic voltages (typically 3.3V) and high-voltage driving outputs.
Interface: Support for high-speed differential signaling (like mini-LVDS or P2P interfaces) to receive image data from the Timing Controller (TCON).
Precision: Internal digital-to-analog converters (DACs) for accurate grayscale (Gamma) reproduction.
Note for Repair Professionals: If you are seeking this part for a "tab bonding" repair, it is crucial to match the part number exactly, as COF chips are typically not interchangeable due to unique pinout configurations and bonding pitches. COF - 易華電子
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
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.
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.
