In the 2025 COB LED market price avalanche and production capacity carnival, Lehman Optoelectronics, the industry's first A-share listed company, broke through with technological innovation. Relying on more than 20 years of deep cultivation in the LED display field and 8 years of COB technology iteration, the first-mover advantage has officially launched the next generation HD King COB series products based on the core original PSE(COB Pixel Engine) patent to the global market, with the main model QS0.9. This new product, which brings together more than a dozen cutting-edge technologies and patents, not only accurately cuts into the incremental market of ultra-high-definition large screens with a spacing of 0.9mm, but also injects new technology-driven vitality into the current COB market where supply and demand are unbalanced with its core advantages of nobility and less expensive. Accelerate the implementation process of the era of 8K ultra-high-definition giant screen immersive experience.
Technology precipitation: PSE patents build a global moat
As a technology leader in the LED large-screen industry, Lehman Optoelectronics 'accumulation in the COB field has long formed a patent barrier + technical closed loop. Since it was the first to launch COB display large-screen products eight years ago, the company has obtained more than 100 domestic and foreign COB cutting-edge display patents. Among them, the core PSE patent has realized the layout of major markets around the world, covering key areas such as China, the United States, Canada, Germany, Japan, and Australia, building a complete technical moat from pixel drive architecture, packaging process to optical design.
The core value of PSE's patented technology lies in achieving a perfect balance of multi-dimensional performance of COB products. Traditional COB products often face industry pain points where high definition and cost are difficult to balance, and brightness and energy conservation are contradictory. Through the innovative design of the PSE pixel engine, Lehman optimizes current distribution and light efficiency conversion efficiency while improving pixel density, and finally achieves a collaborative breakthrough in clarity, price, energy conservation, temperature and life. This technology not only lays the technical foundation for large LED screens in the 8K ultra-high-definition Micro LED era, but also allows energy-saving and environmentally friendly cost-effective COB products to move from concept to large-scale application, breaking the way the previous industry either sacrificed performance to control costs or stuck to high-end The dilemma of high pricing.
New product bright sword: QS0.9 directly hits pain points in the ultra-high definition market
The main model QS0.9 of the HD King COB series launched this time is a masterpiece of Lehman PSE's patented technology. It accurately targets the current rapidly growing demand for ultra-high definition large screens with 0.9mm spacing, covering core scenarios such as professional displays (such as command centers, monitoring large screens) and commercial displays (such as high-end shopping malls and brand showrooms). Its product advantages can be summarized as five-dimensional breakthroughs:
First, the price is people-friendly: on the premise of ensuring 0.9mm ultra-high-definition spacing, PSE patents optimize the manufacturing process and improve yields, and bring product prices to a more competitive range, breaking the inherent recognition that ultra-high-definition must be high., providing the possibility for the industry to popularize ultra-high-definition COB large screens;
The second is extreme energy consumption: Relying on PSE's patented current optimization and heat dissipation design, QS0.9 consumes 50% less energy than traditional COB products. Even in the 24-hour command center scenario, it can significantly reduce enterprise operating costs and meet the requirements for green display under dual carbon goals;
The third is temperature controllability: the innovative packaging structure and heat dissipation path design make the working temperature of the screen lower than the human body temperature (below about 36℃), completely solving the problem of reducing the life of traditional LED large screens during high-temperature operation, combined with low power consumption characteristics, product service life is extended by more than 30% compared with the industry average;
The fourth is the professionalization of image quality: the high refresh rate (up to 3840Hz or above) design allows the picture to be free of smears and flashes, which is perfectly suitable for professional shooting scenes, whether it is a large background screen for live news broadcasts or a virtual studio for film and television production. It can avoid moire and picture tearing during shooting and meet professional-level visual presentation needs;
The fifth is scenario adaptation: In addition to core performance, QS0.9 also has characteristics such as high protection (IP54 dust and water resistance), low maintenance cost (single point of maintenance, maintenance efficiency increased by 60%), etc., which can not only cope with commercial scenarios. High-frequency use can also adapt to complex outdoor and semi-outdoor environments, broadening the application boundary of COB products.
Industry value: Injecting disruptive momentum
In the current critical period of reshuffle in the COB market when production expansion and low utilization coexist, the launch of Lehman Optoelectronics's new generation of HD King COB products is not only a reflection of the company's own technical strength, but will also bring to the entire new LED display industry chain. Three core values:
The first is to reshape the logic of competition: Different from the extensive competition in which some companies exchange price for volume, Lehman takes PSE's patented technology as the core and opens up the market through technology cost reduction rather than production capacity, setting a benchmark for technology-driven growth for the industry., guiding the COB market from a price war to a value war;
The second is to activate industrial chain collaboration: Large-scale production of QS0.9 will drive the technological upgrades of upstream core materials (such as high-purity packaging adhesives and microchips) and midstream equipment (such as high-precision die bonders and testing equipment), and at the same time provide downstream integration. Companies provide cost-effective ultra-high definition solutions, forming a positive cycle of technological breakthroughs and demand growth industrial chain upgrades;
The third is to accelerate the implementation of 8K: 0.9mm spacing is a key node for 8K ultra-high-definition display (8K 100-inch large screen requires a spacing of 0.9mm and below). The launch of QS0.9 has enabled the 8K giant screen to move from high-end customization to batch application. Whether it is a private giant screen in a home theater or an immersive exhibition hall in a science and technology museum, it is possible to achieve 8K experience at a more people-friendly price and promote the popularity of ultra-high-definition display.
Conclusion: Technology leaders 'ways to shuffle and break the game
At a time when the COB LED market is facing the dual test of imbalance between supply and demand and technological iteration, Lehman Optoelectronics 'new generation of HD King COB products have undoubtedly provided a breakthrough sample for the industry to build technical barriers with core patents and balance market demand with multi-dimensional performance., activate the incremental market at a people-friendly price. This will not only allow Lehman to take the lead in the current market reshuffle, but will also promote the transformation of the entire COB industry from barbaric growth to high-quality development.
As industry experts have said, the ultimate winners in the COB market must be companies that can not only see through technological trends, but also accurately match market needs. With PSE patented technology and new QS0.9 products, Lehman Optoelectronics has not only grasped the technical outlet of 8K ultra-high definition, but also solved the core pain point of high cost performance in the current market. Its exploration may provide reference for more industry players and jointly promote the LED display industry is moving towards a new stage of ultra-high definition, low energy consumption, and widespread popularization.
