Organic Light-Emitting Diodes, or OLEDs, are a type of display technology that uses organic compounds to emit light when an electric current is applied. These diodes are made from carbon-based materials, which allow them to produce vibrant colors and deep blacks, making them popular in screens for smartphones, televisions, and other devices. Unlike traditional LEDs, which use inorganic materials, OLEDs are thinner and more flexible, enabling innovative designs like curved or foldable screens. They also offer better energy efficiency and faster response times, enhancing the viewing experience for users across various applications.
