World’s First 270-inch TFT Micro-LED Unveiled: Vistar-Chenxian Lead the Next-Generation Large-Format Display Era

At the 2025 World Display Industry Innovation and Development Conference held in Chengdu, China, Chenxian Optoelectronics unveiled the world’s first 270-inch TFT-based Micro-LED display. The announcement marks a new milestone in the development of China’s Micro-LED industry and is the result of close collaboration with Vistar, a Visionox-affiliated company specializing in Micro-LED technology.

The 270-inch large-format display achieves a 0.7 mm pixel pitch and 8K resolution (33 million pixels). With TFT-based active-matrix (AM) driving technology, each pixel is controlled independently, solving the brightness non-uniformity issues common in LED screens while delivering perfect blacks, high contrast ratios, and vivid color reproduction. This makes it ideal for professional cinemas, premium home theaters, command centers, and commercial display applications.

Alongside this flagship model, Chenxian unveiled several new products: a 13.55-inch P0.7 Micro-LED splicing module, a 27-inch P0.7 textured display, and a 19-inch P0.4 transparent Micro-LED screen. The modular design ensures high flatness and minimal seams, enabling scalability for large displays. The transparent model offers 72 % transmittance and supports touch interaction, providing a seamless fusion of digital imagery and real-world environments. Through these developments, Chenxian has established a comprehensive Micro-LED technology ecosystem encompassing materials, equipment, processes, modules, and complete display systems.

The company’s growth has been driven by its collaboration with Visionox and its subsidiary Vistar. Founded in 2020, Vistar specializes in Micro-LED productization and module integration, assembling the Micro-LED tiles manufactured by Chenxian into panel units and integrating drive modules. The tiling process-involving alignment, calibration, and fine adjustment-is carried out by Vistar’s System Integration (SI) engineering division, ensuring the precision required for large-format panels.

Vistar’s investment and mass-production roadmap also highlights the rapid pace of its expansion. A pilot line valued at USD 160 million broke ground in August 2020 and achieved lighting success in May 2021. In 2023, the company began construction of its first mass-production (MP) line worth USD 400 million. Following lighting completion in December 2024, full-scale mass production is scheduled for April 2025, with a USD 1 billion large-scale TFT-based line planned for 2026.

The unveiling of the 270-inch Micro-LED display demonstrates Chenxian’s emergence as a global leader in both technological innovation and production capability. The vertical collaboration structure between Vistar and Chenxian is accelerating the commercialization of Micro-LED technology and strengthening the overall competitiveness of China’s display industry.
