Første rullebare og transparente microLED display er på vej

Halvlederproducenten Smartkem vil i samarbejde med displayleverandøren AUO udvikle verdens første rullebare og transparente microLED display med afsæt i unik transistorteknologi (in english).

Smartkem, positioned to power the next generation of displays using its disruptive organic thin-film transistors (OTFTs), has partnered with AUO, the largest display manufacturer in Taiwan, to jointly develop the world's first advanced rollable, transparent microLED display using Smartkem’s technology.

- We believe that collaborating with global display industry leader AUO to develop a novel microLED display puts Smartkem’s technology on the frontier of microLED display commercialization. Our unique transistor technology is expected to enable display manufacturers to efficiently produce microLED displays, making mass production commercially viable. Smartkem’s technology has the potential to take today’s microLED TVs from high end market prices of $100,000 down to mass market prices, explains Ian Jenks, Smartkem Chairman and CEO, and he continues:

- Because our transistors are processed at such a low temperature compared to other technologies, we are able to pour them directly on top of the microLEDs, completely eliminating the problematic mass transfer and laser welding processes required with other technologies. The key feature that enables the development of this microLED display is our unique low temperature process that allows the use of low-cost, flexible plastic rather than glass. We believe that, if successful, this collaboration will be a significant milestone for Smartkem in its road to commercialization, and for microLED display product development using our technology.

Dr. Wei-Lung Liau, Chief Technology Officer of AUO, adds:

- AUO has dedicated years to developing the ultimate MicroLED display technology, forging alliances with ecosystem partners to enable mass production. In this collaboration, AUO has developed groundbreaking technologies that boost the high transparency and free-form in applications of MicroLED. With proprietary materials from Smartkem and the OTFT production process from ITRI, we are collaboratively developing the world’s first rollable MicroLED display for potential commercialization with cost advantage. We believe this will create new opportunities for the display industry and continue to expand value chain partner cooperation and influence.

Leading display analyst and DSCC (Display Supply Chain Consultants) CEO, Ross Young, comments this way:

- This is an exciting project that, if successful, will demonstrate the cost effectiveness of Smartkem’s technology in the most demanding of MicroLED applications, and could generate substantial market interest.

Smartkem’s disruption to the MicroLED display market

Smartkem believes it is poised to transform the display industry with a new class of microLED displays that are low-cost, thin, transparent, flexible and lightweight. This is made possible by Smartkem’s OTFTs that are processed at an industry comparatively low temperature, enabling them to be processed directly on top of microLEDs in the manufacturing of microLED displays, eliminating the need for mass transfer and laser welding processes required by existing technology.

This introduces an entirely new 'Chip-First' display architecture to the display market that is not currently possible using other transistor technologies. Additionally, Smartkem’s low temperature feature enables processing of Smartkem’s OTFTs on a plastic substrate, rather than glass, that is low-cost, thin, transparent, flexible and lightweight.

The project between Smartkem and AUO will commence on January 1, 2025. The collaboration has been awarded a grant from the 2024 Taiwan-UK Research & Development Collaboration, supported by The Taiwanese Ministry of Economic Affairs and Innovate UK, part of UK Research and Innovation (UKRI).

The 2024 UK-Taiwan Collaborative R&D Initiative has invested more than £10 million this year to promote bilateral industrial technology research and development cooperation. The nine award-winning projects will promote the joint development of advanced technologies in fields such as electrical information communication, biomedicine, and electromechanical by Taiwan-UK enterprises.
