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.
