As LED display pixel pitches break the P1.0mm barrier, advancing toward P1.9 and beyond into the micro-LED era, 4K and 8K ultra-high-definition visuals are moving from specialized command centers into corporate boardrooms and even home theaters. However, this inward race for pixel density has ignited a different kind of “heat wave” within the industry.
On one hand, the market competition is heating up. With the rapid maturation and production capacity release of COB technology over the past two years, technical stability and industry standardization are quickly leveling the playing field. The direct consequence is an inevitable slide into homogenization, where price wars become the most straightforward competitive tool.
On the other hand, end-users are facing thermal anxiety. Against the global backdrop of the “Dual Carbon” goals, energy efficiency has become a critical direction for LED display products. As notorious power consumers, the high energy consumption and heat generated by LED displays during prolonged operation create significant pain points for users: soaring electricity costs, operational safety concerns, and complex maintenance.
Where the micro-LED trend meets industry pain points, Ledman has identified a core demand. The company is committed to deeply integrating its COB technology with the real-world needs of the end-market, striving to create more efficient, energy-saving, and higher-fidelity “cold screen” products. Today, Ledman offers a new solution for diverse application scenarios.
Introducing the Ledman “UHD King Icescreen QS0.9”
On November 11, Ledman officially launched its next-generation COB display product, the “UHD King Icescreen QS0.9”, to the global market at a grand launch event in Shenzhen. Leveraging proprietary PSE patented technology, the product precisely targets the rapidly growing P0.9mm pitch ultra-HD large-screen market, suitable for full-scenario applications like command and control centers, digital signage, and professional meeting spaces.
The “UHD King Icescreen QS0.9” incorporates more than ten of Ledman’s cutting-edge technologies and patents, boasting five key advantages: Ultra-Stability, Ultra-Clarity, Ultra-Efficiency, Ultra-Cool Operation, and Ultra-Comfort, delivering a comprehensively upgraded user experience. Its name highlights two core value propositions.
Redefining Reliability for Continuous Operation
The “UHD King Icescreen QS0.9” ensures long-term operational stability through its innovative “AI Low-Power Cold Screen System,” achieving a breakthrough in failure-free performance. This system is built on three core technologies:
- SmartCool AI Technology: Intelligently manages power for optimal display performance with minimal energy draw.
- PowerBalance Technology: Enables hyper-precise voltage control for unparalleled stability.
- TrueBlack Technology: Ensures lossless direct display on a dark base for perfect contrast.
Most notably, the panel surface temperature measures just 29.5°C, lower than the human body temperature. This cool operation not only allows for comfortable tactile interaction but also significantly extends the screen’s lifespan, making it a true “touchable cold screen.”
Uncompromised Visuals at a Micro Pitch
The “UHD King Icescreen QS0.9” delivers not just robust performance but also stunning ultra-high-definition visuals, characterized by its Ultra-Clarity, Ultra-Stability, Ultra-Efficiency, Ultra-Cool Operation, and Ultra-Comfort.
At the launch event, Ledman captivated the audience with a series of compelling live demonstrations, including creative “Ice Melt,” “Energy Saving,” and “Ultra-HD” challenges.
In the Ice Melt Challenge, after 30 minutes, the ice cube on the conventional COB product had completely melted, while half remained on the “Icescreen Master” P0.9, vividly demonstrating its superior heat management.
In the Energy Saving Challenge, while being powered by power banks of identical capacity, the conventional COB product went dark after 40 minutes. The “Icescreen Master,” however, retained over 50% of its charge, showcasing a remarkable energy efficiency advantage.
In the Ultra-HD Challenge, without prior knowledge of which product was Ledman’s, the audience voted based on perceived clarity and image quality. Ledman emerged as the clear winner by a significant margin.
These demonstrations not only highlighted the exceptional energy-saving performance of the “UHD King Icescreen QS0.9” but also provided tangible proof of Ledman’s relentless pursuit of technological innovation.
Leveraging its “high-performance, low-threshold” advantage, the “UHD King Icescreen QS0.9” perfectly meets the market’s need for a balance between effect and price. The product received an enthusiastic response at the launch, with pre-orders far exceeding expectations.
The Moat Behind Ledman’s Icescreen Technology
The outstanding performance of the “UHD King Icescreen QS0.9” is not an overnight achievement. It stems from Ledman’s continuous dedication in core technologies like COB, PSE, and PM Glass Substrate.
Ledman’s COB journey began in 2013. The project was formally launched in 2014, culminating in the mass production of its COB-based Micro LED ultra-HD display products in 2018. Through subsequent R&D iterations, Ledman has accumulated over 100 domestic and international patents for advanced COB display technology.
As COB technology matured, Ledman keenly identified the market’s urgent need for energy savings and sustainability, innovatively integrating its self-developed PSE patented technology into COB displays. Ledman’s core, original PSE patent now has protection in major global markets, including China, the US, Canada, Germany, Japan, and Australia.
It is this combination of technologies that brings Ledman’s energy-saving claims to life. For instance, its earlier PSE COB Ultra-HD Energy-Saving Icescreen consumes 50% less power than comparable products.
The market has responded warmly. In the first half of 2025, revenue for Ledman’s PSE Energy-Saving Icescreen products grew by 13.9% year-over-year, demonstrating strong market competitiveness.
Yet, Ledman’s exploration continues. To further optimize the cost and performance of Micro LED, the company is proactively developing its PM Glass Substrate technology. Ledman has already achieved small-batch trial production of PM-driven glass substrate Micro LED display panels and is actively building a new patent moat around this technology.
Breaking the Mold with “Icescreen,” Ledman Leads the 8K Ultra-HD Era
In the “heated” battlefield of LED displays, Ledman has chosen to be a “cool” disruptor. Instead of getting mired in price wars, Ledman returns to the essence of user value. With its “Icescreen” as a differentiated spearhead, it targets the industry’s core pain points of high energy consumption and heat, delivering a product that offers superior value.
With the grand debut of the “UHD King Icescreen QS0.9,” Ledman’s product portfolio is becoming increasingly comprehensive. We have reason to believe that with its leading cold screen technology, Ledman is using product success to drive partner success, powerfully enabling the upgrade of the LED display industry and accelerating the full arrival of the immersive 8K ultra-HD giant screen era.
