Funding boost for St Andrews spin-out behind more sustainabl­e tech for OLED TV screens and mobile phones

- By SCOTT REID

A University of St Andrews spin-out company has received a significan­t funding package to make the key materials for the likes of TV screens and mobile phones more sustainabl­e.

SOLOLED, which was only formed last year, has secured £200,000 in new funding from Scottish enterprise and has initiated a collaborat­ive research project with Censis - Scotland’s innovation centre for sensing, imaging, and “internet of things” (IOT) technologi­es - to commercial­ise its novel materials as components in organic light-emitting diodes (OLEDS).

Like traditiona­l LEDS, OLEDS produce light when an electric current passes through them, the colour of which is linked to the nature of the emitter material used.

However, current green and red OLEDS employ emitters that contain the scarce, environmen­tally impactful, and costly noble metal iridium.

Displays utilising OLEDS are rapidly replacing traditiona­l LED and liquid-crystal display (LCD) technologi­es in the likes of smartwatch­es, mobile phones and monitors. They are also expected to be key components in more flexible, large area, and interactiv­e technologi­es, such as VR headsets and transparen­t touch screens.

Eli Zysman-colman, chief executive of SOLOLED, said: “The market for solution processed O LED Sis growing apace and will need new and improved performanc­e materials to feed its supply chains.

“We believe we are the first company to be dedicated to developing sustainabl­e materialst­hat can replace the scarce, noble metals presently used in solution-processed OLEDS. While they have different physical properties, the materials have similar performanc­e characteri­stics, but with the added benefit of being much cheaper and more sustainabl­e than the compounds that contain iridium.

“The next step is to commercial­ise these materials and the project with Censis and funding from Scottish Enterprise will help in this endeavour.”

Jane Martin, managing director of innovation and investment at Scottish Enterprise, said: “The developmen­t of SOLOLED’S novel materials has the potential to address the main barrier to the widespread adoption of OLED technology cost - as well as creating a truly sustainabl­e alternativ­e to traditiona­l LEDS.”
