LED TV backlight strips Features:

Precise Compatibility with Multiple TV Models

This TV light strip is designed to precisely match several 55-inch models from Panasonic and TCL (e.g., TH-55FS435Q, L55M5-AD), with a 1064mm length that aligns perfectly with the backlight zones. The connector pins and definitions are identical to the original design, with an insertion tolerance of ≤0.1mm. The 4pcs/set configuration covers the screen fully, eliminating the need to distinguish between models and sizes. It resolves issues like light leakage and uneven brightness that arise from using universal strips across different models.

High Brightness and Uniform Display

As a core component, this LED TV backlight strip uses 12 high-color rendering LED chips with 3V constant voltage drive, achieving a luminous efficiency of 235lm/W. The chips are equipped with 120° wide-angle optical lenses, combined with a light guide structure to transform point light sources into a uniform surface light. The actual brightness uniformity reaches ≥97.2%, with color accuracy (ΔE) ≤2.6. This effectively eliminates dark corners and light spots on the screen, restoring 4K details and true-to-life colors.

Efficient Heat Dissipation for Long-Term Durability

The backlight strip uses a widened 1.5mm aluminum substrate, with an improved thermal conductivity of 2.4W/m·K. Coupled with hollow heat dissipation channels, this ensures efficient heat dissipation, keeping the LED junction temperature below 53°C during operation. After 72 hours of high and low-temperature cycle testing (from -20°C to 80°C), the light decay rate is ≤2.8% after 10,000 hours. This ensures a lifespan of over 8 years, solving the common issue of "brightness halving after 3 years" with typical strips and lowering long-term replacement costs.

Durable and Secure with Anti-Falling Technology

The LED beads are encapsulated using high-temperature-resistant technology, with a solder joint adhesion force of 4.0N, far exceeding the industry standard of 2.5N. This ensures no risk of detachment during installation or transportation. The PCB board is coated with an insulating, moisture-resistant layer, making it suitable for use in humid environments and preventing bead short-circuit failures. The brightness variation within the same batch is ≤1.5%, ensuring uniform screen brightness after installation without local dark spots or uneven lighting.

Easy Plug-and-Play Compatibility

The backlight strip is precisely calibrated to match the original voltage and current parameters, with a wavelength deviation of ≤2nm. It seamlessly integrates with the TV's backlight driver IC without issues such as flicker or overcurrent alarms. Featuring a standardized connector design, no soldering or rewiring is necessary—simply "remove the old and plug in the new" for a hassle-free replacement. This process takes less than 10 minutes for a technician, significantly improving repair efficiency without the need for specialized tools or equipment.
