"An Organic Light-Emitting Diode (OLED) is a type of display technology that produces light using organic (carbon-based) materials. Unlike traditional light sources that need a backlight, OLEDs emit light on their own when an electric current passes through them. This makes them thinner, lighter, and more flexible than conventional displays. OLEDs are known for their vibrant colors, deep blacks, and wide viewing angles, which is why they are commonly used in high-end smartphones, TVs, and wearable devices. Because each pixel in an OLED display can be turned on or off individually, they are also more energy-efficient when displaying darker images"-- $C Provided by publisher.
