About Us

Helio is commercialising materials for brighter, more colourful and lower power displays.

Building on fundamental patents exclusively licensed from Oxford and Cambridge Universities, Helio is developing perovskite-based materials for colour conversion and is scaling them to pilot production.

Our materials are helping to drive the evolution in display architectures from colour filtering to pixel-level colour conversion. This fundamental change is significant for large-area OLED, microOLED and potentially future LCD architectures.

Helio offers a unique combination of colour conversion efficiency, narrow emission and high optical density to enable the highest performance colour conversion applications. We are engaging with the world’s leading panel makers and display innovators to bring these amazing materials to market.

We look forward to a bright and colourful future with Helio!

Our Staff

We employ the best material scientists and engineers in the world in our field and we look for qualified, experienced and passionate researchers to join our existing team.

We are located in custom built labs in beautiful surroundings at the Wood Centre for Innovation in Oxford

If you want to be part of a well-funded, fast-growing start-up, and feel that your skills and experience match current career opportunities at Helio, we'd like to hear from you.

Our Founders

Helio Display Materials was spun out from the Universities of Oxford and Cambridge by our founders, Professors Sir Richard Friend and Henry Snaith. The fundamental IP created by these eminent scientists is exclusively licensed to us by the universities. 

Professor Sir Richard Friend FRS FREng 

Distinguished for his work with organic polymers and the electronic properties of molecular semiconductors, Sir Richard was Cavendish Professor of Physics at the University of Cambridge from 1995 to 2020. He holds a wealth of prestigious awards and honours celebrating his achievements including a knighthood for services to physics gained in 2003.

Professor Henry Snaith FRS

Henry gained his PhD in 2005 for research on polymer solar cells, supervised by Sir Richard. He holds numerous accolades for his work, and currently leads the Photovoltaic and Optoelectronic Device Group at Oxford University.

In 2010, Henry founded the now hugely successful Oxford PV, leaders in perovskite solar cell technology.

Our Investors

Our investors include leading venture capitalists Longwall Ventures, BGF and IP Capital who each bring a wealth of experience in supporting start-up technology companies. They were attracted by our: 

  • Excellent prospects of being first to market with the next generation of display materials technology 
  • Promise to bring superior efficiency and lower costs to the industry through metal halide perovskites
  • Fundamental IP in light emitting applications of perovskites exclusively licensed from Oxford and Cambridge universities
  • Rapid speed of progress 
  • Close relationship with the founders, their active involvement assuring that our developments are based on the world leading science base in perovskites
