Helio Display Materials

Helio Display Materials is a company that develops perovskite-based materials for the display industry. Founded in 2017 as the first joint spin-out from Oxford and Cambridge Universities, Helio creates proprietary materials for digital screen displays. The company's technology focuses on photoluminescent and electroluminescent perovskite-based materials that can be used in LCD, OLED, and Micro-LED displays. Helio's materials are designed to produce brighter and more colorful displays while significantly reducing power consumption.

The company's perovskite materials have several advantages over existing technologies. They emit a very narrow spectrum of light, which maximizes color gamut and allows displays to reproduce a wider range of colors. Helio's materials can convert light from one color to another efficiently in a very thin film, which is crucial for optical design and manufacturing cost considerations. For example, the company's materials can convert 99.9% of incident blue light into green light in a film less than five microns thick. This results in displays with more vivid colors and lower power consumption.

Helio aims to partner with companies in the display supply chain to tap into the display module market, which the company estimated to be worth USD 120 billion as of March 2022. The company's technology is particularly relevant for next-generation screens, whether based on LCD, OLED, or Micro-LED. Helio claims that its materials can increase LCD power efficiency by up to 70%, which could significantly impact mobile device battery life and reduce carbon emissions from televisions.

As of May 2022, Helio Display Materials had a team of ten employees and was planning to continue recruiting throughout the year. The company moved into custom-built labs at the Wood Centre for Innovation in Oxford in April 2022, which provided the specialized wet lab facilities required for their research and development efforts.
