Nt61219h-c6021a Cof Datasheet [better] Direct

While full official datasheets are often proprietary to manufacturers, technical summaries from RGB TV Parts and repair documentation reveal several core characteristics:

While proprietary Novatek documents are tightly controlled under non-disclosure agreements, empirical benchmarks and component specifications delineate the foundational electrical behavior of the NT61219H series: Specification Profile / Value Novatek Microelectronics Package Type Chip-on-Film (COF) / TAB Primary Application LCD TV Panels, High-Resolution Monitors Logic Supply Voltage ( VDDcap V sub cap D cap D end-sub ) 2.5V to 3.6V Analog Supply Voltage ( VLSDcap V sub cap L cap S cap D end-sub VAAcap V sub cap A cap A end-sub ) 13.5V to 18.0V (Gamma & Source Driver rail) Output Channels

The NT61219H-C6021A belongs to the or TAB (Tape Automated Bonding) family of drivers. In this architecture, the driver IC is mounted directly onto a flexible plastic film. Primary Functions

Enables fine-pitch connection between the IC and the display. nt61219h-c6021a cof datasheet

With the data in hand, he performs a "COF bypass". Using a wire thinner than a human hair, he jumps a signal from a healthy part of the board directly to a tiny copper pad on the NT61219H film. It’s microsurgery for machines. NT51021 - Phoenix Display

The output side consists of hundreds of microscopic, high-density pins (

The NT61219H-C6021A integrates a high-speed digital shift register, data latches, and a multi-channel digital-to-analog converter (DAC) onto a flexible printed circuit (FPC) film. Source Driver (Column Driver) While full official datasheets are often proprietary to

Chip-on-Film (COF) / Tape Carrier Package (TCP) Application: LCD/LED Panel Gate Driver (Row Driver) Logic Voltage ( VDDcap V sub cap D cap D end-sub ): Typically 3.3V High-Level Drive Voltage ( VGHcap V sub cap G cap H end-sub ): 20V to 35V Low-Level Drive Voltage ( VGLcap V sub cap G cap L end-sub ): -5V to -15V Key Pin Functions & Voltage Points

While the full OEM datasheet is confidential to panel manufacturers, reverse-engineered and service manual data provide the following reliable specifications:

This article provides a comprehensive overview of the , covering its technical specifications, application in screen repair, and critical features for technicians and engineers. What is the NT61219H-C6021A? With the data in hand, he performs a "COF bypass"

: Heat the damaged COF tab using a specialized heating pad and gently peel it away from both the PCB and the LCD glass edge.

The term COF stands for . Unlike traditional surface-mount technology where an integrated circuit (IC) is soldered to a hard PCB, a COF integrates the silicon driver die directly onto a flexible polymer substrate.
