SHENZHEN, November 11, 2025 – The grand product launch event for the “Ledman’s UHD King Icescreen” was successfully held in Shenzhen. The event gathered industry leaders, university experts, numerous mainstream and trade media representatives, and partners from across the country, with over 500 attendees present. The launch was also live-streamed simultaneously via Tencent Video, LEDinside Video Channel, Hangjiashuo Video Channel, and Ledman’s official video and Douyin channels, allowing a global audience to witness this technological innovation milestone in the LED display industry.
PART.01 Industry Leaders Gather to Witness New Industry Directions
Li Mantie, Founder, Chairman, and President of Ledman, delivered a keynote speech titled “The Future of LED Display.” He elaborated on the development path and future trends of LED displays through “Eight Core Perceptual Dimensions” – Ultra-High Definition, Ultra-Immersive, Ultra-Low Power Consumption, Crystal-Cool Screen, Ultra-Stable, Ultra-Comfortable, Consumer-oriented; and “Five Technology Evolution Paths” – from DIP to SMD, SMD to COB, COB to MiP, COB to COG, and COB to PSE.
Jiao Yang, Deputy Secretary-General of the World Ultra High-Definition Video Industry Alliance (UWA), highlighted that the 8K ultra-high-definition industry is ushering in trillion-level development opportunities, becoming a core growth driver for the digital economy. He noted that Ledman, as a council member of the alliance, deeply cultivates core technologies like COB and PSE, supports national 8K infrastructure development, provides 8K Ultra HD family wall products and office display solutions for China Media Group (CMG), deeply participates in 8K channel trial broadcasts and live-streaming experiments, completed the world’s first AVS3 standard-based 8K live broadcast, and provided a 275-inch 8K Micro LED display and solutions for the International Broadcast Center at the Milan Winter Olympics, gaining high recognition for China’s ultra-high-definition technology on an international top-tier platform. Professor Sun Xiaowei, Chair Professor at Southern University of Science and Technology (SUSTech), praised Ledman’s PSE technological strength, affirming its five major advantages: Ultra-Stable, Ultra-High Definition, Crystal-Cool Screen, Ultra-Low Power Consumption, and Ultra-Comfortable. He mentioned his long-term focus on Ledman’s development, with interactions spanning nearly a decade, and fully affirmed Ledman’s role in driving the display technology industry forward.
PART.02 Core Technologies Address Pain Points; Challenge Verifies Performance Visually
01 Grand Launch of the UHD King Icescreen
Zhou Jie, General Manager of Ledman’s Product Management Department, conducted the grand product launch, directly addressing core pain points in the current LED display market, such as sudden black screens, signal interruptions, large-area dead pixels, and color distortion.
Citing Nobel Laureate Arrhenius’s “Ten-Degree Rule” – for every 10°C increase in operating temperature, the expected service life is halved, he emphasized the newly launched “UHD King Icescreen.” Based on Ledman’s exclusively developed AI Low-Power Cool Screen System, which includes three core technologies – Lingying AI Low-Power Intelligent Display, Zhiheng Ultra-Precise Voltage Control, and Xuanjia Bottom-Black Lossless Direct Display – it achieves five core advantages: Ultra-Stable, Ultra-High Definition, Ultra-Low Power Consumption, Crystal-Cool Screen, and Ultra-Comfortable, adaptable to full-scenario application requirements.
02 Hardcore Challenge Visually Verifies Product Performance
The launch event featured three hardcore challenge PKs: Ultra HD Blind Test, Energy Saving Challenge, and Ice Melting Challenge, comparing the performance of the “Ledman UHD King Icescreen” with a conventional COB product, both with the same pixel pitch of 0.9mm, under identical conditions.
Ultra HD Blind Test
Display Quality Selection
Energy Saving Challenge
Power Consumption Showdown
Ice Melting Challenge
Screen Temperature Battle
In the Ultra HD Challenge, two displays with obscured brand logos played identical content. Attendees voted for the display they perceived as having better visual quality. Ultimately, the “UHD King Icescreen” won with a high score of 189:88.
In the Energy Saving Challenge, using power banks of the same capacity to power both displays at the same brightness, after 40 minutes, the conventional COB product’s power bank drained completely, causing a black screen, while the power bank for the Ledman UHD King Icescreen still had over 50% charge remaining.
In the Ice Melting Challenge, equal amounts of ice were placed on both display products. After 30 minutes, the ice on the conventional COB product had completely melted, while a significant mound of ice remained on the Ledman UHD King Icescreen.
PART.03 Policy Support Ignites Market; Pre-order Frenzy Validates Strength
Huang Longyuan, General Manager of Ledman’s Domestic LED Business Division, announced on-site sales policies, specifying exclusive Double 11 day pre-order benefits and comprehensive support rights, instantly igniting the atmosphere. Clients on-site actively placed pre-orders or added to existing orders.
As a master integrating technological accumulation in the COB ultra-high-definition field, the “UHD King Icescreen” is positioned as a core product that is “easy to sell and profitable,” with its market potential highly recognized by partners.
Towards the end of the event, Chairman Li Mantie announced that the final pre-order volume for the Ledman UHD King Icescreen had exceeded 12,000 square meters, far surpassing the expected target. He, along with the heads of the company’s marketing team, jointly announced the successful launch voyage of the Ledman UHD King Icescreen.
QS0.9 8K
Energy-Saving Comparison Wall
Interactive Conference AlO
The Ledman UHD King Icescreen QS0.9 8K display on site, having been continuously lit for 24 hours, impressed clients with its low-temperature performance and vibrant picture quality. The smooth interaction of the Ledman Interactive Conference AlO allowed guests to personally experience its intelligence and convenience. The two Energy-Saving Comparison Walls used in the challenges, featuring convenient functions like one-click lifting, one-click start-up, and ready-to-use out-of-the-box without debugging, along with the real-time demonstrated low power consumption advantage, were highly favored by partners. Many guests indicated on the spot their intention to place orders for use in their company showrooms.
This new product launch not only represents a major breakthrough in COB technology but also sets a new industry benchmark, propelling LED displays into the “Crystal-Cool Screen Era.”
