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"+).

This component serves as the critical bridge between the main TV scaler board and the panel's source driver ICs, managing signal integrity and power distribution. nt61219h-c6021a cof datasheet

In a typical 55-inch 4K TV panel, you will find 12 to 16 NT61219H-C6021A COFs bonded directly to the bottom edge of the glass. Each chip drives 720 columns. For a 3840x2160 panel (4K), 3840 total columns / 720 outputs = approximately 5.3 chips, so manufacturers use 6 chips per side, or staggered across top and bottom.

NT61219H-C6021A is a specialized Chip-on-Film (COF) module primarily used as a driver integrated circuit (IC) in LCD and LED television panels

. These components are critical for translating digital signals from the TV's logic board into the electrical voltages required to control the individual pixels of the display. Technical Overview and Functionality Chip-on-Film (COF)

module, the IC is mounted directly onto a flexible plastic substrate rather than a traditional rigid PCB. This "Tape Automated Bonding" (TAB) design allows the chip to be folded behind the screen, enabling thinner bezels and more compact display designs. Alibaba.com The NT61219H-C6021A typically functions as a source driver

, which manages the data lines that determine the brightness and color of each pixel. In common repair scenarios, these chips are often associated with panel models like the LC320DXJ-SHAE Key Specifications and Procurement

While full internal schematics are often proprietary to manufacturers like Novatek, the following logistical and technical details are standard for this part: Application : LCD/LED TV panel repair and manufacturing. Package Type : COF/TAB (flexible film). Typical Pinout Signals Below is the recommended external component setup for

: Like other COF ICs in this series, it manages critical voltages such as (Gate High), (Gate Low), (Logic Power, typically 3.3V), and Procurement

: Available through specialized electronic parts suppliers like RGB TV Screen LCD Repair Machine Minimum Order Quantity (MOQ)

: Typically ranges from 5 to 20 pieces depending on the vendor. Common Failure Symptoms and Repair

Technicians often look for the NT61219H-C6021A datasheet when diagnosing common "panel bond" failures. Symptoms of a faulty COF IC include: Vertical Lines : One or more permanent vertical lines of a specific color. Horizontal Bars

: Often caused by gate driver failure, though source drivers can cause similar artifacts. No Image/Dark Screen

: If the COF IC responsible for the main data lines fails, the entire screen or a large section may remain black. STMicroelectronics Community Repairing these components requires a COF bonding machine Reference Resistor (Rset):

, which uses heat and Anisotropic Conductive Film (ACF) to bond the flexible driver back onto the glass panel or PCB. Lcd/Led Tv Panel's Cof Ic Datasheet.#Pro Hack Lcd/Led Tv Panel's Cof Ic Datasheet.#Pro Hack

Bending Radius Limit: The C6021A film can withstand 50,000 bend cycles at a radius of 1.5mm (180° dynamic bend) before copper fatigue.

The C6021A film layout is designed for a 1:1 mapping between IC bumps and panel data lines. Pin groups typically include:

Important Layout Note: The nt61219h-c6021a requires strict impedance matching on input differential pairs (100Ω ±10%). Any deviation causes signal reflection and display artifacts.
