Helio is commercialising perovskite materials in light-emitting applications such as display panels, whether LCD, OLED or μLED. Perovskites are of strong interest as they are highly efficient and tuneable emitters of pure light. This enables increased brightness, colour range and power efficiency.

Helio is a joint spin-out from Oxford and Cambridge Universities and will initially commercialise materials for colour conversion. Quantum dots have started to be adopted in backlight films for colour conversion, however, the more significant opportunity is in the pixel structure itself, where perovskites are strongly differentiated due to their extraordinarily high optical density.
