Gyd-9e Datasheet =link= (2024)

The is a versatile constant current power supply board primarily used as a driver for LED backlight strips in LCD televisions and monitors. This component is often sought out by DIY electronics enthusiasts and repair professionals to replace faulty integrated high-voltage power boards or to upgrade standard displays with high-brightness LED backlighting. Technical Specifications

Solder the interface harness wires securely to these identified locations, and plug the opposite end into the GYD-9E input header.

The GYD-9E is a specialized, high-efficiency , also commonly referred to as an LED backlight driver or inverter. It is an after-market component, primarily designed to repair or upgrade LCD screens in monitors, televisions, and other display panels that have failed or are being converted from older CCFL (Cold Cathode Fluorescent Lamp) technology to modern, energy-efficient LED strips. gyd-9e datasheet

The is a highly versatile, universal constant current LED backlight driver board engineered primarily to upgrade older 15-to-24-inch LCD monitors and televisions from CCFL (Cold Cathode Fluorescent Lamp) to energy-efficient LED backlighting. Driven by a specialized high-efficiency PWM control step-up/step-down architecture (frequently utilizing the DF6113/DF6113A step-down/step-up controller chip), this board ensures highly stable, uniform current delivery to keep LED replacement strips operating reliably without dimming or flickering. It features a wide input voltage tolerance, dual output connectivity, and support for analog/PWM dimming interfaces, making it a staple tool for bench technicians and display hardware modifiers. Technical Specifications & Operating Parameters
