‘A whole new generation of displays’: researchers develop RGB LED out of miracle material perovskite, paving the way for self sensing, solar powered displays — but its hour-long service life needs to be improved first


The majority of personal gadgets feature LCD and OLED screens, but most just show information. To make these screens do more – like detecting touch or changing light levels – they need additional sensors. Researchers at Linköping University (LiU) in Sweden have invented a new kind of screen where all these sensor functions are built right into the screen’s LEDs.

The breakthrough in display technology was achieved by crafting RGB LED displays from a “miracle” material known as perovskite. This development marks a potential revolution for future screens of smartphones, computers, and tablets.
