SMARTKEM, INC. MICRO-LED DISPLAY PAPER PUBLISHED IN LEADING SCIENCE JOURNAL, NATURE COMMUNICATIONS

MANCHESTER, England, Nov. 7, 2023 /PRNewswire/ -- SmartKem, Inc. (OTCQB: SMTK), a company seeking to reshape the world of electronics with its disruptive organic thin-film transistors (OTFTs) that can drive the next generation of displays, announced the publication of a scientific paper by the UK's leading peer reviewed science journal, Nature Communications (having a 2-year impact factor of 17.7 in 2021).

The paper, titled "Wafer-scale organic-on-III-V monolithic heterogeneous integration for active-matrix micro-LED displays" was a collaboration between SmartKem and Prof. Xiaojun Guo's group at Shanghai Jiao Tong University. The paper was co-authored by SmartKem's Chief Technology Officer, Dr. Simon Ogier, and SmartKem engineers Dan Sharkey, Andrew Baker, and Alejandro Carreras who were also responsible for the display backplane fabrication and display testing using SmartKem's patented TRUFLEX® OTFT technology with its benefits of low temperature processing and high charge mobility.

Such low temperature (<150 °C) organic last integration processes can thus be compatible with micro-LED processes for direct fabrication of the active-matrix OTFT array on top of the LEDs without affecting the micro-LED performance. The first OTFT-driven active-matrix micro-LED displays are demonstrated with highest brightness of 150,000 nits and highest resolution of 254 pixels-per-inch. This work would open a route for realizing active-matrix micro-LED displays through direct fabrication of high-density OTFT arrays onto the micro-LED plane with fully compatible processes.
