The NT61219H-C6021A is a specialized Chip-on-Film (COF) module, often referred to as a TAB (Tape Automated Bonding) IC, manufactured by Novatek. It is a critical driver component used in the repair and manufacturing of LCD and LED TV panels. This IC acts as an interface between the TV's T-Con board and the actual liquid crystal panel, managing the electrical signals that control pixel activation. Core Technical Specifications
While full engineering datasheets for COF ICs are typically proprietary to manufacturers like Novatek, trade listings and repair guides provide the following verified commercial specifications: Product Type: Driver IC / COF TAB Module. Application: LCD/LED TV screen repair and panel bonding.
Compatibility: Used in various 32-pin and high-definition panel configurations.
Condition: Typically sold as "100% New" for professional bonding/repair applications. Manufacturer: Novatek (identified by the "NT" prefix). Role in TV Repair and Maintenance nt61219h-c6021a cof datasheet
The NT61219H-C6021A is essential for addressing common display issues such as vertical lines, screen flickering, or complete loss of image. Repairing these faults often involves a process called COF Bonding, where a specialized machine is used to replace the damaged chip on the flexible film.
Technicians often use "flying line" or bypass diagrams when a specific trace on the original COF is damaged. These diagrams map the internal pinouts to allow for manual wiring (jumpers) to restore signal flow without replacing the entire module. Sourcing and Availability
Because these components are highly specialized, they are generally sourced through electronic component distributors and specialized TV repair wholesalers. LCD COF TAB NT61219H-C6021A
A: No. The NT61219H series typically uses Mini-LVDS. V-by-One HS is handled by the T-Con, not the source COF. Check your T-Con output signals.
Unlike traditional Chip-on-Glass (COG), the nt61219h-c6021a uses COF packaging, where the silicon die is mounted directly on a flexible polyimide film. This provides:
While the full datasheet is NDA-controlled, comparable source drivers share:
| Parameter | Typical Value | |-----------|----------------| | Output channels | 960–1440 | | Input interface | mini-LVDS (8–10 pair) | | Output voltage range | 0–15 V | | Supply voltage (VDD) | 3.3 V | | Analog supply (AVDD) | 8–12 V | | Max data rate | 1.2–1.8 Gbps per pair |
The NT61219H-C6021A is a Chip-on-Film (COF) package, a critical component used primarily in the assembly and repair of LCD and LED television panels. Manufactured by Novatek, these COF ICs act as the bridge between the television's source PCB and the glass LCD panel, driving the signals required to display images. Technical Specifications and Role
While full manufacturer datasheets for specific COF models are often proprietary and restricted to authorized repair centers or panel manufacturers, the following technical characteristics are standard for the NT61219H series: Reference Resistor (Rset):
Function: It serves as a source driver IC. It receives digital image data and converts it into the analog voltages needed to control the liquid crystals in the display.
Package Type: COF (Chip-on-Film). The IC is mounted on a flexible plastic substrate, allowing it to be folded behind the screen to minimize bezel size.
Application: Commonly found in high-definition TV panels from brands like Samsung, LG, and various Chinese manufacturers (e.g., BOE, CSOT).
Physical Interface: It features ultra-fine pitch "input" and "output" pins that must be bonded to the panel using Anisotropic Conductive Film (ACF) and specialized bonding machinery. Common Use Cases in Repair
In the repair industry, the NT61219H-C6021A is frequently sought after to fix specific screen defects. When this chip fails—often due to "gate/source COF burnout" or physical damage—the TV may exhibit: Vertical lines or bars on the screen. Half-screen blackouts or "frozen" images. Thermal failure (the chip becomes excessively hot). Sourcing and Replacement
Replacing a COF IC is not a DIY task for general consumers. It requires:
ACF Bonding Machine: A high-precision machine that uses heat and pressure to align the IC pins with the panel's electrodes.
Microscopic Alignment: The pins are measured in microns, requiring cameras and monitors for proper positioning.
Cleanroom Environment: To prevent dust from interfering with the electrical connections during the bonding process. Optional RC Filter:
