The Ledman QS Series Icescreen is a flagship indoor Ultra-HD Micro LED display line utilizing advanced COB (Chip-on-Board) packaging paired with Ledman's proprietary PSE (Pixel Sharing Engines) technology. Dubbed the "Icescreen" due to its revolutionary thermal management that keeps the screen surface exceptionally cool during continuous operation, this series delivers extreme resolution, massive energy savings, and certified eye protection. It stands as a premium, high-impact solution for command control centers, broadcasting studios, high-end corporate conference rooms, executive boardrooms, and luxury indoor digital showrooms.

Key Features & Advantages

  • Proprietary PSE (Pixel Sharing Engines) Technology: Enables the screen to easily achieve ultra-fine pixel pitches (down to 0.79mm and 0.9mm). This cutting-edge architecture outputs crisp, native 4K or 8K Ultra-HD video walls with remarkable image detail and zero pixelation at close-range viewing.

  • Extreme Energy Saving (Up to 50%): Features a technological breakthrough that boosts image brightness without raising power consumption. It cuts electrical usage by up to 50% compared to traditional alternative indoor screens, drastically lowering operational costs and total cost of ownership.

  • Cool-to-the-Touch "Icescreen" Technology: Driven by an AI-powered, high-efficiency cooling layout, the surface operating temperature of the screen remains locked between 29.5°C to 32.1°C—significantly cooler than the human body. This eliminates the uncomfortable ambient heat radiation common with large conventional video walls.

  • Broadcast-Grade Cinematic Performance: Boasting an ultra-high refresh rate of up to 7680Hz, the display guarantees perfectly smooth motion transitions with no ghosting or visible scan lines. It completely eliminates camera flickering and moiré effects during live professional video recordings or broadcast streams.

  • Certified Eye Health & Safety: Complies with strict EMC CLASS B standards for ultra-low radiation emissions. Additionally, it integrates a specialized soft-light technology and holds TÜV Rheinland Low Blue Light certification, ensuring long-term eye comfort for critical control room operators or audiences.

  • Rugged Multi-Layer Surface Protection: Utilizing an advanced surface encapsulation molding process, the display face is anti-bump (impact-resistant), dust-proof, moisture-proof, anti-static, and highly resistant to minor chemical or solvent exposure, making it resilient in high-traffic commercial spaces.
