(Organic LED) A display technology that offers rich colors, high contrast, deep blacks, wide viewing angle, low power and fast response time for action scenes. Instead of silicon or gallium, which LEDs are made of, OLEDs use "organic" carbon emitting layers. OLED screens are found in TVs, smartphones, tablets, watches and VR/AR headsets. Increasingly, laptop displays and monitors are OLED, but screen burn-in is a problem when the same toolbars and logos remain on screen for weeks on end. For more OLED technology details, see OLED layers. See LED and PHOLED.

Transparent OLEDs (TOLEDs) function in heads-up displays and even as window shades. Flexible OLEDs (FOLEDs) can be folded, and OLEDs are also used for general-purpose ceiling and light fixtures. OLED's thinness, transparency and flexibility make it a versatile display technology for the 21st century. See TOLED, FOLED, WOLED and OLED lighting.

From 11 to 77 Inches
In 2007, Sony's 11" XEL-1 OLED TV (top) was the first commercial OLED TV. To emphasize its thinness, the tuner was separated from the screen. The intense colors captivated audiences but not its USD $2499 price tag. Seven years later, LG unveiled a 77" 4K OLED (bottom). By 2020, a 65" OLED cost less than the 11" OLED.

organic development

Internal growth based on adjusting and adapting to the situations at hand. For example, new information systems might evolve incrementally based on user feedback rather than starting anew with a system from a third party. See organic search.

organic search results

The ranking of a website on a search engine results list that is due entirely to the search engine's algorithms evaluating the site rather than from a paid ad. The websites of companies that pay for ads are ranked either on the first page or very high in the results list. However, without paid ads, websites are ranked based on their popularity and the content of their pages, the latter often manipulated by optimization specialists who try to trick the search engine (see page ranking and search engine optimization). Also called a "natural search." See vertical search engine and search engine.

organic semiconductor

A semiconductor made from a carbon-based material. For example, light-emitting polymers (LEPs) are organic semiconductors. Contrast with inorganic semiconductor. See LEP.
