Organic Light-Emitting Diode: a display technology in which each pixel produces its own light, enabling deep blacks and thin, flexible screens.
Traditional LCD screens use a backlight shining through layers of liquid crystals and filters. In an OLED display, each pixel is made of organic compounds that glow when electricity passes through them. Pixels can turn off completely, producing true black and very high contrast.
OLED panels are common in premium smartphones, televisions, smartwatches, and increasingly laptops and monitors. Because they do not need a backlight, they can be thinner and even flexible, enabling foldable phones. Showing dark content can also save power. Drawbacks include higher cost and the possibility of burn-in, where static images such as on-screen icons leave faint permanent marks over long periods, though manufacturers use various techniques to reduce this.
