LED TV backlight strips Features

I. Superior Optical Performance for a Stunning Picture Quality Experience

Features: Utilizes high-quality LED chips from top global brands (such as Epistar and San'an) as the core light source, employing a precise optical lens design.

Advantages: This ensures your TV delivers extremely high peak brightness, deep dark scenes, and exceptionally high contrast, resulting in a clear and layered picture. Ultimately, it significantly enhances the overall visual appeal of the product,

making picture quality your brand's most powerful competitive advantage and easily meeting the demanding requirements of high-end consumers.

Features: Achieves industry-leading brightness and color uniformity through precise binning technology and a scientific LED layout.

Advantages Fundamentally solves common problems such as dark corners, localized bright spots, or yellowing patches on the screen, delivering a pure, flawless, and color-consistent display. This not only greatly improves end-user viewing 

satisfaction but also significantly reduces the risk of after-sales complaints and returns due to uneven display, protecting your brand reputation.

Features: Supports high color rendering index (CRI > 90) and wide color gamut coverage (up to 92% DCI-P3 and above).

Advantages: 

Enables more realistic and accurate reproduction of the original colors of images, especially excelling in the representation of reds and greens. This allows your TVs to deliver stunning visual effects 

with rich colors, natural,transitions, and abundant detail when playing HDR content,perfectly aligning with next-generation ultra-high-definition display standards and becoming a powerful technical selling point in your product promotion.

II. Ultra-Long Lifespan and Ultimate Reliability: Building a Worry-Free Supply Chain

Features: Utilizes high thermal conductivity PCB materials (such as FR-4) and a scientifically designed copper-based heat dissipation channel, optimizing heat dissipation efficiency from a physical structure perspective, ensuring a product 

lifespan of 50,000 to 70,000 hours.

Advantages: Excellent thermal management capabilities effectively suppress the light decay rate of LED chips, ensuring your TV maintains its original brightness throughout its entire lifespan. This not only extends the durability of the end 

product, creating long-term value for users, but also reduces the risk of mass after-sales service due to batch light decay issues, saving you significant maintenance costs.

Features: Each batch of products undergoes multiple extreme environmental reliability tests, including high temperature and humidity, thermal shock, and dual 85 testing, simulating the aging process after years of use.

Advantages: We pre-test products in harsh environments for you, ensuring that every product delivered to you can operate stably in various complex climates and usage environments. This "design-to-reliable" philosophy greatly reduces the 

field failure rate of your products, building a solid quality reputation for your brand.

Features: Implements 100% aging test and rigorous incoming quality control (IQC) processes.

Advantages: 

This comprehensive quality control system effectively eliminates early-stage defective products before shipment, keeping the production line defect rate (DPPM) at an extremely low level. This means your production line can 

avoid downtime and rework due to LED strip issues, ensuring a smooth and efficient production process, directly reducing costs and increasing efficiency for you.
