LED backlight strips are a key component of LCD TV display systems, consisting of multiple LED chips arranged on a metal substrate. This particular LED backlight strip (models: POLA 2.0 42-inch Type A Rev0.1 2021.10.14, POLA 2.0 42-inch Type B Rev0.1 2021.10.14) is specifically designed for 42-inch TVs, including the 42LN5300, 42LN5400, and other 42LN/42LA series models. It employs a professional optical configuration, converting point light sources into uniform surface light sources through a light guide plate. This 42-inch TV backlight requires extremely precise matching of voltage (3V) and optical parameters, directly affecting brightness uniformity, color accuracy, and overall display quality. The component uses a standardized interface design, ensuring perfect compatibility with the original TV driver circuitry.

LED TV backlight strips Features:

• Precise Adaptation, Dual Specification Compatibility This LED backlight strip (model: POLA 2.0 42" series) uses 5+4 LED chips arranged with an accuracy of ±0.1mm. With a dual-length design (460MM+395MM), it perfectly matches the original structure of 42-inch TVs. It provides a stable 3V voltage output with current fluctuations controlled within ±2%. It is compatible with multiple 42-inch models such as the LG 42LN5300 and 42LA6200, and its interface is identical to the original TV, requiring no modification during installation—just plug and play.

• Optical Optimization, Uniform High Brightness Equipped with a custom optical lens, the 5+4 LED chips deliver a color temperature of 6500K ±200K (in line with the D65 white light standard). Combined with a 120° wide light angle, the brightness uniformity of the 42-inch screen exceeds 92%. It completely eliminates dark spots on the screen, providing clear and vivid visuals from any viewing angle, offering a high-quality visual experience for models like the 42LA6150-ZB.

• Aluminum Base, Durable and Stable The backlight strip uses an enlarged and thickened aluminum base for excellent heat dissipation. The LED chips have a lifespan of over 50,000 hours with light decay controlled within 5%. The aluminum base is resistant to oxidation and operates stably in environments ranging from -20°C to 80°C, with an overall lifespan exceeding 8 years. This provides long-term reliable backlight support for models like the 42LN5700, significantly reducing future maintenance costs.

• Energy-Efficient and Balanced Performance Running at 3V, each LED consumes a reasonable amount of power, delivering excellent energy savings compared to traditional backlight solutions. While meeting the high brightness display requirements of 42-inch models, it achieves a balance between energy efficiency and performance, making it an ideal choice for everyday viewing.

• Plug and Play, Easy Installation The interface is fully compatible with LG's 42-inch TV series (e.g., 42LN5400, 42LA6130-ZB), supporting plug and play with no need for any circuit modifications. The installation process is simple and efficient, allowing both professional technicians and DIY enthusiasts to easily complete the setup.

• Reliable Quality, Low Maintenance The backlight strip uses imported anti-fall-off LED beads, providing high brightness without flicker, ensuring a comfortable viewing experience. The set comes with a 5 pairs/set configuration, including spare strips for future maintenance. The product complies with RoHS environmental standards and uses lead-free soldering, with quality control throughout the entire production process, ensuring the backlight system's reliability and durability.

LED TV Backlight strips FAQ :

Q: Can I use the backlight strip in a high - humidity environment? A: Our backlight strips are designed to withstand normal indoor humidity levels. However, high - humidity environments, such as bathrooms or basements with poor ventilation, may cause damage over time. If you need to use it in such an area, proper waterproofing and ventilation measures are recommended.

Q: Are there any software updates available for the backlight strip? A: Some of our more advanced backlight strip models may have software updates. These updates can improve performance, add new features, or fix any minor glitches. You can check our official website or the product manual for information on how to check for and install updates.

Q: Can the backlight strip be controlled via a mobile app? A: Certain models of our backlight strips support mobile app control. This allows you to adjust settings like brightness, color, and lighting patterns conveniently from your smartphone. Check the product description to see if your chosen strip has this functionality and for details on how to pair it with the app.

Q: How does the backlight strip affect the overall power consumption of the TV? A: The backlight strip adds a relatively small amount of power consumption to the TV. Our strips are designed to be energy - efficient, and the additional power draw is usually negligible. However, the exact consumption depends on the strip's brightness setting and the length of use.

Q: What is the lifespan of the backlight strip under continuous use? A: Under normal continuous use conditions, our backlight strips have a lifespan of approximately [X] hours. This lifespan can be affected by factors such as temperature, power supply stability, and usage patterns.

Q: Can I install the backlight strip on a TV that has been previously repaired? A: In most cases, you can install the backlight strip on a previously repaired TV. However, it's important to ensure that the repair work didn't damage any components related to the backlighting system. If you're unsure, it's best to consult a professional technician or contact our support team for advice.
