LED TV backlight strips Features:

Precise Fit, Plug-and-Play Installation Designed for Haier 39-inch models, these strips (model RF-BS390001SE30-0701 A0 and equivalents) are sized at 760 mm to match the original backlight layout. The connectors align perfectly with the factory driver board, so the set can be installed directly with no rewiring. The three-piece configuration covers the full panel area, preventing the brightness issues caused by mismatched models. Beginners can complete the replacement in about ten minutes by following the printed labels.

Bright, Flicker-Free, Comfortable Viewing A 7-LED imported setup with a stable 3V drive delivers high efficiency of up to 215 lm/W. The optical lens design provides a wide 120° beam, reducing dark corners and hot spots with measured brightness uniformity above 95%. The flicker-free output helps ease eye strain, ensuring smooth, comfortable picture quality for both home viewing and commercial displays.

Wide Aluminum Cooling for Long Service Life A widened, thickened aluminum substrate with 2.2 W/m·K thermal conductivity and vented cutouts helps maintain LED temperatures below 60°C during operation. Reinforced LED packaging provides 3.2 N adhesion strength. After 72 hours of high/low temperature cycling (-20°C to 75°C), brightness decay remains under 3% per 10,000 hours, supporting a lifespan of over eight years.

OEM-Level Compatibility Calibrated to Haier factory specifications, these strips maintain wavelength deviation within 2 nm and current variation within ±5 mA. Batch-to-batch brightness differences stay under 2%. Once installed, they pair seamlessly with the original driver IC with no flicker, over-current alerts, or adjustment needed—reducing the risk of secondary repairs.

Durable and Safe for Transport A reinforced anti-bend PCB, combined with protective cushioned packaging, minimizes damage during international shipping. The simple structural design and straightforward steps make installation easy without specialized tools, suitable for both bulk trade orders and end users replacing the parts themselves.
