China’s LED display industry is at a pivotal turning point, shifting from fragmented operations to collaborative growth.
On March 6, during the ISLE 2026 exhibition in Shenzhen, China’s first group standard, LED Display Control Interface and Communication Protocol Based on TCON, was officially released. Led by Beijing Novatech Microelectronics Co., Ltd., the standard was jointly compiled by 16 core industrial chain enterprises, including Unilumin Group, Nanjing Lopu, BOE Crystal Core, Hikvision, Dahua Technology, and Uniview. It was finalized and approved by the China Optics and Optoelectronics Manufacturers Association (COEMA).
This standard systematically defines for the first time the terminology, interface electrical parameters, and communication protocol specifications for core components such as timing controllers, bridges, and drivers in TCON-based LED display control systems. It effectively resolves long-standing technical barriers and collaboration challenges in the industry.
Yao Dahu, Secretary of the Party Branch and Secretary-General of COEMA, stated that a sound standard system is crucial for improving production efficiency, ensuring product quality, driving technological innovation, optimizing industrial structure, promoting industrial coordination, and advancing industrial upgrading. He called on the entire industrial chain to strengthen cooperation, take innovation as the guide and standards as the guarantee, and jointly support the construction of a modern industrial system.
Breaking the Deadlock: From "Universal Charger" Chaos to Standardized Uniformity
"The current LED display control system is just like the old 'universal chargers'—convenient on the surface, but a huge headache for the industry," said Lin Mingfeng, Chairman of Unilumin Group, at the launch conference. For a long time, China’s LED display industry has suffered from fragmented interface standards and privatized protocols. These issues have led to overstocking as companies prepare for different systems, the need for multiple spare parts for global operation and maintenance, and low production efficiency due to equipment incompatibility.
Drawing a parallel to the Type-C interface unification driven by mobile terminals, Lin noted that standardized uniformity will ultimately benefit the entire industry. "Users want increasingly simple operations that do not require professional personnel. This is an irresistible trend."
He revealed that Unilumin has mass-produced five-in-one products compliant with the LED-TCON standard, which integrate multiple functions and greatly simplify display systems. "We have adopted them on a large scale, proving this path is feasible." He urged traditional system manufacturers to embrace the new era, shifting "from fragmented operations to joint creation—leaving complexity to us and simplicity to users."
During the concurrent ISLE 2026 exhibition, multiple leading enterprises also disclosed progress in the commercialization of LED TCON technology. Novatech, together with Xida Electronics and MTC Crystal Display, showcased innovative products such as 8K ultra-high-definition large screens and 135-inch conference all-in-one machines equipped with domestic LED TCON solutions and driver ICs under the unified standard. These became successful full-chain application cases from chip R&D to terminal products.
"As the owner of the world’s largest LED display production capacity, China is fully capable of evolving from a capacity exporter to a standard setter," said Zhang Jinfang, Chairman of Novatech.
Currently, China accounts for more than 80% of the global LED display production capacity. Previously, large-size displays long followed Japanese and South Korean standards. In recent years, leading enterprises such as BOE and CSOT have launched independent interface standards. The release of the unified LED TCON standard marks that domestic substitution has extended from hardware manufacturing to rule-making, significantly enhancing the industrial chain’s security and independence.
Driving Innovation: Unlocking Imagination for the Consumer Market
Standardization and application of a "unified language" for LED displays help unlock new market growth. Traditionally, LED large screens have been mostly used in commercial, industrial, and high-end consumer scenarios due to high costs and complex technology. With consumer electronics becoming more accessible and prices of 100-inch TVs dropping below 20,000 yuan, the cost of LED displays has fallen sharply, awakening consumer demand for large-size screens.
"Our mobile phones and computers can connect across screens, but what about LED displays larger than 100 inches? Most of the time, they sit idle," Zhang Jinfang said in a panel discussion at the LED TCON standard launch conference. Novatech aims to connect "the last screen" to the mobile internet to unlock greater commercial value.
"The fundamental reason so many leading enterprises are responding is that everyone sees the huge business opportunities for these screens in the future," Zhang revealed. Novatech’s LED TCON chips already generated significant revenue last year, and "growth will accelerate."
Market data shows the global LED display market size is expected to exceed 10 billion US dollars in 2026. Meanwhile, the Ministry of Industry and Information Technology has explicitly identified new displays (including LED) as one of the six emerging pillar industries to foster and expand during the 15th Five-Year Plan period.
Facing vast development opportunities, the LED industry is standardizing technical languages and interface specifications at an early stage. This promotes technical connectivity and product compatibility across the industrial chain, enables seamless integration and mutual empowerment of innovations from different enterprises, and lays a standardized foundation for the LED display industry to develop toward high integration, cost-effectiveness, and high-end positioning. Ultimately, it will help secure a more advantageous position in the global market amid new trends such as Micro LED and AI+display.
Numerous enterprises are preparing to launch standard-compliant products, with initial synergy effects emerging across the industrial chain. To ensure the standard delivers real value, the LED TCON Application and Promotion Working Group was officially established upon the standard’s release.
Focused on standard implementation, popularization, and iteration, the working group plans to hold multiple seminars in 2026 to effectively bridge the "last mile" of technology commercialization and promote wide adoption of the standard across the industry.
