An Organic Light-Emitting Diode (OLED) is 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, allowing them to produce vibrant colors and deep blacks. OLEDs are commonly used in screens for televisions, smartphones, and other devices due to their thin profile and flexibility. One of the key advantages of OLED technology is its ability to provide better contrast and energy efficiency compared to traditional Liquid Crystal Displays (LCDs). Since each pixel in an OLED display generates its own light, they can turn off completely to create true black, enhancing the overall image quality.
