Researchers at Carnegie Mellon University have made a groundbreaking development in smartphone displays by creating a technology that incorporates physical keys into flat screens. Unlike the traditional on-screen keyboards that rely on haptic feedback, this new technology uses embedded electroosmotic pumps to generate actual bumps on the display.
The thin panel, placed behind the OLED screen, contains miniaturized hydraulic pumps that can create tactile bumps and form a physical keyboard when required. Each pump is individually controlled, allowing for various functions and providing users with a more immersive and realistic typing experience.
