The wave of display technology development is surging forward, and Micro-LED, with its unparalleled performance potential, is attracting the attention of the display industry. However, the road to industrialization of Micro-LED from the laboratory to the market is fraught with difficulties. The yield bottleneck of mass transfer, the high manufacturing cost, and the complex driving technology are all insurmountable obstacles.
In this race of display technology revolution, Chenxian Optoelectronics, as a "latecomer," has chosen the most difficult but also the most promising technological path—TFT-based Micro-LED. This is not only a milestone for China's new display industry, but also a risky move by Chenxian Optoelectronics as a "breakthrough player who dares to tackle tough challenges," amidst a triple game of risk, technology, and market.
The interplay of risk, technology, and market forces has shaped Chenxian's Micro-LED technology.
In 2020, Chenxian Optoelectronics was officially established. At that time, although the Micro-LED concept was hot, there were very few companies worldwide that had truly invested and made substantial progress, especially for the TFT-based route, which was more technically challenging. Although TFT glass substrates have natural advantages in terms of precision, flatness, driving methods, and the ability to achieve flexible and transparent forms in the future, their complex processes, compatibility with semiconductor processes, high initial resource investment, and unknown acceptance in the display market all made this path exceptionally "narrow".
Facing the triple challenges of risk, technology, and market, under the leadership of General Manager Dr. Huang Hsiu-Chi, Chenxian Optoelectronics has demonstrated remarkable execution and innovation capabilities, achieving breakthroughs in TFT-based Micro-LEDs by prioritizing innovation and speed.
In its second year of operation, Chenxian Optoelectronics quickly completed the Micro-LED principle verification and pilot development in less than 10 months, and built the first full-process pilot line for Micro-LED in mainland China, covering LTPS driving backplane, mass transfer, repair to module.
In 2024, Chenxian Optoelectronics once again achieved remarkable speed by lighting up the only TFT-based Micro-LED mass production line in mainland China with a total investment of 3 billion yuan. With its strong action and execution capabilities, it overcame the difficulties of Micro-LED mass production one by one.
Currently, Chenxian Optoelectronics has overcome key technical challenges such as mass transfer, driving architecture, seamless splicing, and hybrid binning. It has independently developed several innovative achievements, including high-speed mass transfer technology, glass-based TFT hybrid driving solutions, TFT-based double-sided LTPS-TFT backplane technology, and hybrid assembly technology. The company has applied for over 1,000 valid patents in the field of Micro-LED display technology, leveraging its strong technical strength and innovation capabilities to achieve mass production of Micro-LED technology.
A risky move in the field of Micro-LED technology has now become a brilliant one, putting Chenxian Optoelectronics at the forefront of Micro-LED display technology innovation.
Chenxian Optoelectronics' Latest Masterpiece—The World's Thinnest TFT-Based Micro-LED Display <br /> Leveraging its profound understanding of Micro-LED technology development trends, Chenxian Optoelectronics continues to create a rich portfolio of high-end Micro-LED products, primarily based on TFT technology. This year alone, Chenxian Optoelectronics has successively released the world's first mass-produced 135-inch P0.7 Micro-LED splicing screen and the world's first 88-inch P0.5 TFT-based Micro-LED splicing screen, demonstrating to the industry Chenxian Optoelectronics' solutions to the challenges of mass-producing Micro-LED applications.
At InfoComm China 2025, Chenxian Optoelectronics once again showcased its latest mass-production masterpiece—the world's thinnest TFT-based Micro-LED cabinet. With a thickness of less than 10mm at its thinnest point, the cabinet achieves zero-micron physical seams and a height difference of less than 10 microns, setting a new record once again. This extends LED displays beyond commercial applications, enabling them to demonstrate the full capabilities of Micro-LED's ultra-high definition and ultra-thin design in high-end scenarios such as conferences and education.
