Chenxian Optoelectronics launches the world’s thinnest TFT Micro-LED display

The development wave of display technology is rushing forward, and Micro-LED is attracting the attention of the display industry with its unparalleled performance potential. However, from the laboratory to the market, the road to Micro-LED industrialization is full of thorns. The yield bottleneck of mass transfer, high manufacturing costs, and complex driving technology are all insurmountable gaps.

On the track of this display technology revolution, Chenxian Optoelectronics, as a "latecomer", has chosen the most difficult but also the most promising technical path - TFT-based Micro-LED. This is not only a milestone for China's new display industry, but also a risky move made by Chenxian Optoelectronics as a "game-breaker who dares to bite the hard nut" in the triple game of risk, technology and market.

The triple game of risk, technology and market created Chenxian 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 around the world that really invested in and made substantial progress, especially the TFT-based route, which is more technically difficult. Although TFT glass substrates have natural advantages in precision, flatness, driving methods, and future flexibility and transparency, their process complexity, compatibility with semiconductor processes, high initial resource investment, and unknown acceptance in the display market all make this path extremely "narrow."

Faced with the triple challenges of risk, technology and market, Chenxian Optoelectronics, under the leadership of General Manager Dr. Huang Xiuqi, is based on innovation and aims to win quickly, showing amazing execution and innovation power, and achieving breakthroughs in TFT-based Micro-LED.

In the second year of its establishment, Chenxian Optoelectronics quickly completed the Micro-LED principle verification and pilot development in less than 10 months, and built the first LTPS drive system in mainland China. Micro-LED full-process pilot line from moving backplane, massive transfer, repair to full module coverage;

In 2024, Chenxian Optoelectronics once again completed the lighting of the only TFT-based Micro-LED mass production line in mainland China with a total investment of 3 billion yuan at an astonishing speed. With extremely strong action and execution, it has overcome the difficulties of Micro-LED mass production one by one.

At present, Chenxian Optoelectronics has overcome key technical problems such as mass transfer, drive architecture, seamless splicing and hybrid bin, and independently developed many innovative achievements such as high-speed mass transfer technology, glass-based TFT hybrid drive solution, TFT-based double-sided LTPS-TFT backplane technology and hybrid assembly technology. The company has applied for more than 1,000 valid patents in the field of Micro-LED display technology, and has achieved mass production of Micro-LED technology with its strong technical strength and innovation capabilities.

A risky move in the field of Micro-LED technology has now turned into a wonderful move, allowing Chenxian Optoelectronics to be at the forefront of Micro-LED display technology innovation.
Chenxian Optoelectronics’ latest masterpiece—the world’s thinnest TFT-based Micro-LED display

With its deep insight into the development trend of Micro-LED technology, Chenxian Optoelectronics continues to create a wealth of high-end Micro-LED products with TFT-based technology as its main technical route. Since this year alone, Chenxian Optoelectronics has released the world's first mass-produced 135-inch P0.7 Micro-LED splicing screen, the world's first 88-inch P0.5 TFT-based Micro-LED splicing screen and other products, allowing the industry to see the answers that Chenxian Optoelectronics has given in cracking the application of Micro-LED mass production.

At the InfoComm China 2025 exhibition, Chenxian Optoelectronics once again brought the latest mass production masterpiece-the world's thinnest TFT-based Micro-LED box. The thinnest part of the whole cabinet is less than 10mm, achieving "0" micron physical seams and a height difference of less than 10 microns, setting a new record again. It also allows the LED display to not only be used in commercial displays, but also to play the role of Micro-LED ultra-clear and ultra-thin in high-end scenes such as conferences and education. Comprehensive strength.

As the "ultimate display technology", the application scope of Micro-LED does not stop there. At the exhibition site, Chenxian Optoelectronics also displayed many of the world's first products, allowing the audience to see the charm of Micro-LED.

The new generation of 135-inch P0.7 TFT-based Micro-LED splicing screen created by Chenxian Optoelectronics has the advantage of ultra-high display performance, with a peak brightness of up to 1500nits, a contrast ratio of >6,000:1, pixels of 1.64 million/㎡, and a DCI-P3 color gamut of >98%. Through the integration of AM+TFT drive mode, 0.5T ultra-thin glass as the substrate, high-voltage low-current LED chips, fully-laminated aluminum brackets and other technologies, the screen has also formed four major advantages: eye protection, splicing effect, high reliability, and energy saving, helping the efficient application of Micro-LED technology;

For emerging transparent display applications, Chenxian Optoelectronics demonstrated the world's first P0.5 TFT-based Micro-LED transparent screen product. Chenxian Optoelectronics uses micron-level LED chips and high aperture ratio TFT transparent substrates to achieve a single-screen transmittance of 72%, a record for transparent displays. It also has an ultra-high brightness of 3000nits, allowing it to be used in vehicle-mounted transparent displays, high-end commercial windows, museum cultural relic showcases, aerospace, rail transit and other scenarios.

For the home theater application market, Chenxian Optoelectronics has brought an 88-inch P0.5 TFT solution to benchmark Micro-LED TV products from international manufacturers. Facing the demand for higher-definition displays in the consumer market, Chenxian's 88-inch P0.5 TFT solution has a pixel density of 3.93 million/㎡, a peak brightness of 2,000 nits, a contrast ratio of over 10,000:1, a vertical and horizontal viewing angle of 170°, and a DCI-P3 color gamut exceeding 99%. The plan paved the way for Chenxian Optoelectronics to explore the consumer market in the future.
