The LED TV backlight strip is a key component in the LCD TV display system, consisting of multiple LED chips arranged on a metal substrate. The LED TV backlight strip (models MS-L1717 V1, JL.D40071330-001DS-M, 01D400307V1-X4) is specifically designed for 40-inch TVs including 40L3750VM, 40l48504b, 40L3750, 40L48804M, 40E3, STV-LC40LT0020, 40E2, 40E20DGSWA and other compatible models. It adopts a professional optical configuration with imported lamp beads that are not easy to fall off, providing high brightness, high quality, and no stroboscopic effect. This 40-inch TV backlight requires precise voltage matching (3V) and optical parameters, which directly impact brightness uniformity, color accuracy, and overall display quality. The component features an interface that is the same as the original machine, ensuring perfect compatibility with the TV’s original driver circuit and enabling plug-and-play installation.

LED TV backlight strips Features:

• Precise Compatibility with Multiple 40-Inch Models, Strong Versatility This LED light strip is available in models such as MS-L1717 V1 and JL.D40071330-001DS-M, with a length of 720mm that fits perfectly into the 40-inch TV backlight structure. The strip features 7 LED chips arranged with an accuracy of ±0.1mm. The 3V voltage output is stable, and the current fluctuation is controlled within ±2%. The interface is fully compatible with models like 40L3750VM, 40l48504b, and many others, requiring no modification during installation. It provides a flexible solution for various 40-inch TV backlight systems.

• Imported LED Beads, Exceptional Picture Quality Equipped with imported anti-detachment LED beads and a professional optical design, the light strip offers brightness uniformity of over 92% and flicker-free performance. It effectively eliminates dark areas and light spots on the screen. Whether watching dynamic scenes in movies or static displays for daily use, the strip ensures a clear, detailed, and color-accurate picture on the 40-inch screen, delivering an immersive visual experience.

• Aluminum Base Material, Excellent Durability The light strip features a widened and thickened aluminum base with excellent heat dissipation, allowing it to efficiently channel heat away from the LED chips and prevent performance degradation due to high temperatures. The LED chips have a lifespan of over 50,000 hours, with light decay controlled within 5%. The aluminum base is highly resistant to oxidation and operates stably in environments ranging from -20°C to 80°C, with an overall lifespan exceeding 8 years.

• 3V Low Voltage, Significant Energy Savings Operating at 3V, each LED consumes only about 60% of the power of traditional backlight chips, resulting in lower overall energy consumption. While maintaining the high brightness of 7 LEDs, the system reduces the power consumption of the TV’s backlight, leading to long-term savings on electricity bills while balancing performance and energy efficiency.

• Plug-and-Play, Convenient and Efficient Installation The interface design is fully compatible with the original 40-inch TV models, supporting plug-and-play installation without the need for specialized electrical knowledge or complex tools. The package includes 3pcs/set, and the configuration can be flexibly adapted according to the actual number of TV backlight units. The installation process is simple, time-saving, and user-friendly, making it easy for ordinary users to complete the setup.

• Reliable Quality, Comprehensive After-Sales Support Product code XR1452. The production process undergoes strict quality control, and the LED beads are encapsulated to prevent detachment. The product complies with industry standards, using safe, non-toxic materials. It also comes with comprehensive after-sales support to ensure the stable operation of the 40-inch TV backlight system, providing users with peace of mind.
