LED TV Backlight strips Features：

Precision Manufacturing for Superior Performance
With over a decade of expertise, our state-of-the-art factory leverages advanced engineering and stringent precision standards to produce industry-leading LED backlight strips. We maintain a monthly production capacity of 10,000 units, each undergoing rigorous 24-hour quality inspections to ensure full compliance with technical specifications and a 99.8% product qualification rate. Our vertically integrated process — from automated SMT assembly to final validation — guarantees end-to-end quality control across every manufacturing stage.

Advanced Thermal Management for Extended Lifespan
Designed with oxygen-free copper circuits and a double-layer thickened aluminum substrate, our backlight strips incorporate innovative cooling technology that reduces operating temperatures by up to 30% compared to conventional solutions. Paired with high-thermal-conductivity padding, this system effectively dissipates heat to prevent performance loss and ensure long-term reliability. The result is a product capable of continuous operation exceeding 50,000 hours while maintaining stable brightness and color consistency.

Seamless Compatibility and OEM-Grade Quality
Engineered to original equipment specifications, our backlight strips deliver true plug-and-play integration with major TV brands. A proprietary circuit design ensures stable voltage output (±1% tolerance) and flicker-free performance across 32–85 inch models. Each unit undergoes individual compatibility testing to validate mechanical, electrical, and optical performance — guaranteeing over 95% brightness uniformity, a CRI >95 for realistic color reproduction, and durability that meets or exceeds OEM standards.

LED TV Backlight strips FAQ：

Q: Does this backlight have good heat dissipation?

  A: Of course yes, for instance, designed with broadened and thickened aluminum base so as to achieve rapid heat radiation thereby prolonging its service life.

Q: Is it true that this backlight has consistent brightness?

  A: That’s right, actually, our backlight uses high-brightness, clear and stable illuminant lamp beads without any shadow issues.

Q: Is installing LED TV Backlight strips easy?

  A: The backlight has exactly the same interface as original machine, so you can install it easily by plugging in directly without any other ado involved.

Q: How about the factory output?

  A: Our products are very huge, can reached more than 100,000, and support customization, look forward to cooperating with you.

Q: How to transport the goods to me?

  A: For urgent orders and lightweight, you can choose the following couriers: UPS, FedEx, TNT, DHL, EMS. For heavier weight, you can choose other ways to delivery your goods by air or by sea to save costs, etc.,without worrying about the way you want to ship.

Q: What about the lead time? 

  A:Samples take 3-5 days, and mass production takes 7-14 days—with factory-direct pricing lower than market rates due to our large-scale production and no middlemen to carry out secondary sales.
