QF82V2 LCD Inverter KOE Industrial Backlight Driver Board for Industrial LCD

QF82V2 Product Overview

The KOE QF82V2 is a LCD backlight inverter driver board (also referred to as a CCFL inverter or backlight power supply module) designed for industrial TFT-LCD display applications. This driver board converts low-voltage DC input (12 VDC) into high-frequency AC voltage output required to ignite and maintain stable operation of CCFL (Cold Cathode Fluorescent Lamp) backlight tubes in LCD display panels. The QF82V2 is capable of driving 2 CCFL tubes, making it suitable for 7" to 10.4" industrial TFT-LCD panels commonly found in HMI interfaces, medical monitoring equipment, and factory automation instrumentation.

Why Choose KOE QF82V2 LCD Inverter?

• KOE Display Expertise: Manufactured by KOE (a subsidiary of Kyocera), a global leader in industrial LCD display technology with decades of expertise in designing and manufacturing display components including inverters, driver boards, and TFT-LCD modules for industrial, medical, and automotive applications.

• Reliable CCFL Backlight Drive: The QF82V2 provides stable, high-frequency AC output (typically 500-1000 VAC at 40-80 kHz) required for CCFL tubes, ensuring consistent brightness, uniform illumination across the display, and long CCFL tube lifespan in industrial environments.

• 12VDC Wide Input Range: Operates from standard 12 VDC industrial power bus, compatible with common industrial power supplies and battery-backed systems used in factory automation, process control, and portable medical devices.

• Compact Industrial Design: Small form-factor PCB design with mounting holes for easy mechanical integration into LCD display assemblies, inverters are typically mounted on the rear or side of the display module frame.

• Drop-in Replacement: The QF82V2 is widely used as a replacement backlight inverter for aging industrial displays from manufacturers including Winmate, KOE/Kyocera, NEC, and other industrial LCD module brands.
