Perovskite is one of the focuses of LED research as the material is believed to deliver light with lower production cost. However, the efficiency and stability of perovskite-based LEDs still need to be improved with worldwide research teams continuously working on the material. Helio Display Materials, a spin-off company of Oxford University and Cambridge University, is pushing perovskite LEDs commercialization with the IPs from both universities.

Helio Display Materials aims to leverage its technology to enhance color performance for current light emitters covering LCD and OLED display, as well as optimizing the next-gen display technologies Mini LED and Micro LED. With proprietary technologies, the company is developing color converting film and matrix to transfer blue LEDs to RGB backlight to enhance color saturation. The matrix technology, according to Helio Display Materials, can also apply to Micro LED technology with better power efficiency.

One of the production challenges of Micro LED is to achieve full RGB colors. The manufacture of red Micro LED chips has been confronting difficulties with poor yield and lack of efficiency. Many solutions were proposed for tackling the issue including perovskite.
