LED TV backlight strips Features:

Directional Fit for Easy Installation These R/L-specific TV light strips are precisely sized at 437 mm (right) and 373 mm (left) to match the original 40-inch Samsung backlight layout used in models like the UE40JU6000U. The connectors follow the exact factory pin configuration with tight 0.1 mm tolerance. With 10 strips in the set, the full panel is evenly covered. Just match the markings on the panel and the strips—no soldering, no rewiring, and no trial-and-error.

Flicker-Free, Even Illumination A 5+4 LED design with 3V constant-voltage drive delivers bright, low-blue-light output at up to 225 lm/W. The built-in micro-lens provides a wide 120° beam, achieving high uniformity and reducing hot spots, edge dimming, and visible flicker. This creates a smoother, more comfortable viewing experience for both home use and long-hour commercial playback.

Copper Cooling for Long Lifespan A 1.2 mm pure copper substrate (380 W/m·K) and vented heat-dissipation design keep LED temperatures under control, extending reliability. High-temperature solder and reinforced packaging provide 3.6 N adhesion strength. After 72 hours of thermal cycling from –20°C to 75°C, brightness decay stays within 3% per 10,000 hours—supporting up to eight years of stable performance.

OEM-Grade Compatibility Each strip is calibrated to Samsung’s original optical and electrical standards, maintaining wavelength deviation within 2 nm and current fluctuation within ±5 mA. This ensures smooth operation with the factory driver IC, avoiding issues such as flicker, over-current warnings, or mismatched brightness—common with non-OEM alternatives.

Export-Ready and Damage-Resistant Designed for overseas Samsung 40-inch models, the strips offer a direct drop-in replacement with no modification required. Protective rigid packaging with foam cushioning prevents damage during international transport. The simple structure and clear installation steps make it user-friendly for both bulk buyers and end-users replacing the strips on their own.

LED TV Backlight strips FAQ：

Q: How do your backlight strips compare in terms of color accuracy? A: Our backlight strips are engineered to offer high color accuracy. They are designed to closely replicate true - to - life colors, providing a vivid and immersive viewing experience. Through strict quality control during manufacturing, we ensure that the color output of each strip meets industry - standard color gamut requirements, making colors look rich and consistent across your TV screen.

Q: Can I use the backlight strip in a TV that has been stored for a long time? A: Yes, you can. However, before installing the backlight strip, it's advisable to check the TV for any signs of damage or moisture ingress that may have occurred during storage. Also, let the TV warm up to room temperature if it was stored in a cold environment. This helps prevent any thermal stress on the components. Once you've ensured the TV is in good condition, proceed with the backlight strip installation as per the instructions.

Q: What if I want to upgrade the backlight strip to improve the picture quality? A: Upgrading the backlight strip can potentially enhance picture quality. First, determine the compatibility of the new strip with your TV model. Consider factors like brightness, color temperature, and power requirements. If you're unsure, provide us with your TV's details, and we can recommend an appropriate upgrade. An upgrade might involve a strip with higher - quality LEDs, better heat dissipation, or more advanced dimming capabilities for improved contrast and overall picture performance.

Q: Are your backlight strips resistant to electromagnetic interference? A: Our backlight strips are designed with features to minimize the impact of electromagnetic interference (EMI). We use shielding materials and proper circuit design to reduce the susceptibility of the strip to external EMI sources. This helps ensure stable operation and prevents issues like flickering or color distortion that could be caused by EMI. However, in extremely high - EMI environments, additional precautions may be necessary.

Q: How do I store the backlight strip if I'm not going to install it immediately? A: Store the backlight strip in a cool, dry place away from direct sunlight, heat sources, and humidity. Keep it in its original packaging to protect it from dust and physical damage. If possible, store it in an anti - static bag to prevent electrostatic discharge, which can harm the sensitive components of the strip. This way, the strip will remain in good condition until you're ready to install it.

Q: Can I use a universal backlight strip for different TV models? A: While there are some universal - type backlight strips available, their compatibility can vary. A truly "universal" strip may not fit all TV models perfectly due to differences in physical size, electrical connections, and power requirements. It's always best to choose a backlight strip that is specifically recommended for your TV model. If you have multiple TV models and are considering a universal option, contact us with the details of each TV, and we can advise on the most suitable solution.
