OLED technology, or Organic Light Emitting Diode technology, is a display technology that uses organic compounds to emit light when an electric current is applied. Unlike traditional LCD screens, which require a backlight, each pixel in an OLED display generates its own light. This allows for deeper blacks and more vibrant colors, as pixels can be turned off completely. One of the key advantages of OLED technology is its ability to produce thinner and more flexible screens. This has led to its use in various devices, including smartphones, televisions, and wearable devices. Additionally, OLED displays offer wider viewing angles and faster response times compared to other display technologies.
