The smart screens won’t need separate sensors
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.
Perovskite is renowned for its remarkable light absorption and emission capabilities. This crystalline substance forms the core of the LED and fuels the array of features in the screen.
