We make semiconducting nanocrystals called perovskites. These are nano sized particles which emit light at specific wavelengths. We can tune the wavelength very accurately by tweaking the composition of our materials. Our aim is to use this material in display panels from smart phones to televisions. By using our products, the customers will have two benefits. Firstly, they will see a very pure colour, enhancing the viewer experience. Secondly, the display unit will use considerably less energy, enabling devices to become up to 70% more power efficient.
