OLED displays are a type of screen technology that uses organic compounds to produce light. Unlike traditional LCD screens, which require a backlight, each pixel in an OLED display emits its own light. This allows for deeper blacks and more vibrant colors, as pixels can be turned off completely to create true black. Additionally, OLED displays are thinner and more flexible than other display types, making them suitable for a variety of devices, from smartphones to televisions. Their wide viewing angles and faster response times enhance the overall viewing experience, making them popular in modern electronics.
