Ledman launches the UHD King Icescreen QS0.9 display, which stands out for its low power consumption and superior visual performance.

As LED display pixel pitches break the P1.0 mm barrier and advance toward P0.9 and beyond, entering 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 race toward higher pixel density has triggered another kind of “heat wave” within the industry.

On one hand, market competition is intensifying. With the rapid maturation and release of production capacity for 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 “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 major pain points for users: rising electricity costs, operational safety concerns, and complex maintenance.

At the point where the micro-LED trend meets the industry's main pain points, Ledman has identified a core demand. The company is committed to deeply integrating its COB technology with the real needs of the end market, striving to create more efficient, energy-saving, and higher-fidelity “cold screen” products.

Ledman offers a new solution for diverse application scenarios.

Introducing 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 during a grand launch event in Shenzhen. Leveraging its patented PSE technology, this product targets the ultra-HD large-screen market with P0.9 mm pitch, suitable for full-scenario applications such as command and control centers, digital signage, and professional meeting rooms.

The UHD King Icescreen QS0.9 incorporates more than ten of Ledman’s advanced technologies and patents, and features five key advantages: ultra-stability, ultra-clarity, ultra-efficiency, ultra-cool operation, and ultra-comfort, delivering a fully upgraded user experience. Its name highlights two essential value propositions.

The “cold screen master”: redefining reliability in continuous operation

The UHD King Icescreen QS0.9 ensures long-term operational stability through its innovative AI Low-Power Cold Screen System, achieving breakthrough fail-free performance. This system is built on three core technologies:

• SmartCool AI Technology: intelligently manages power for optimal performance with minimal consumption.
• PowerBalance Technology: enables ultra-precise voltage control for unmatched stability.
• TrueBlack Technology: ensures lossless direct display on a dark base, achieving perfect contrast.

The most notable feature is that the panel’s surface temperature is only 29.5°C, lower than human body temperature. This cool operation not only allows comfortable touch interaction but also significantly extends the screen’s lifespan, making it a true “cold screen to the touch”.

The 'UHD king': impeccable micro-pitch visual quality

The UHD King Icescreen QS0.9 delivers not only robust performance but also stunning ultra-HD visuals characterized by ultra-clarity, ultra-stability, ultra-efficiency, ultra-cool operation, and ultra-comfort.

During the launch event, Ledman impressed the audience with a series of live demonstrations, including the challenges of ice melting, energy saving, and ultra HD.

• Ice-melting challenge: after 30 minutes, the ice cube on a conventional COB product had completely melted, while on the Icescreen Master P0.9 only half had disappeared, demonstrating superior thermal management.
• Energy-saving challenge: powered by external batteries of equal capacity, the conventional COB product went dark after 40 minutes. The Icescreen Master, however, still retained more than 50% of its charge, showing a remarkable energy-efficiency advantage.
• Ultra-HD challenge: without knowing which product was Ledman’s, the audience voted based on perceived clarity and image quality. Ledman was the clear winner by a wide 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 ongoing pursuit of technological innovation.

Leveraging its high-performance, low-threshold advantage, the UHD King Icescreen QS0.9 perfectly meets the market’s need to balance effect and price. The product received an enthusiastic response at launch, exceeding pre-sale expectations.

The technological moat behind Ledman’s Icescreen technology

The exceptional performance of the UHD King Icescreen QS0.9 is not an overnight achievement. It stems from Ledman’s continued dedication to key technologies such as COB, PSE and PM glass substrate.

Ledman’s COB journey began in 2013. The project was formally launched in 2014 and culminated in 2018 with the mass production of Micro LED ultra-HD panels based on COB. Through subsequent R&D iterations, Ledman has accumulated more than 100 domestic and international patents for advanced COB technology.

As COB technology matured, Ledman identified the urgent market need for energy savings and sustainability, innovatively integrating its patented PSE technology into COB displays. Ledman’s PSE patent now has protection in major markets such as China, the U.S., Canada, Germany, Japan and Australia.

This combination of technologies brings Ledman’s energy-saving claims to life. For example, its PSE COB Ultra-HD energy-saving display consumes 50% less power than comparable products.

The market has responded positively. In the first half of 2025, revenue from the PSE Energy-Saving Icescreen line grew 13.9% year-on-year, demonstrating strong competitiveness.

But Ledman’s exploration continues. To further optimize the cost and performance of Micro LED, the company is actively developing its PM glass substrate technology. Ledman has already achieved small-batch pilot production of Micro LED display panels based on PM-driven glass substrate and is building a new patent moat around this technology.

Breaking the mold with Icescreen

In the “heated” battlefield of LED displays, Ledman has chosen to be a “cool” disruptor. Instead of falling into price wars, the company returns to the essence of user value. With “Icescreen” as its differentiated spearhead, it addresses the industry’s biggest pain points: high energy consumption and heat, delivering a product of superior value.

With the grand debut of the UHD King Icescreen QS0.9, Ledman’s product portfolio is becoming increasingly complete. All signs indicate that, with its cold screen technology, Ledman is using product success to drive partner success, accelerating the upgrade of the LED display industry and the full arrival of the immersive 8K ultra-HD giant-screen era.
