OLED screens in mobile devices

OLED screens in mobile devices use organic light-emitting diodes—tiny, flexible materials that emit light when powered. Unlike traditional LCD screens that rely on a backlight, each OLED pixel produces its own light, allowing for deeper blacks, higher contrast, and more vibrant colors. This technology enables thinner displays, better energy efficiency, and wider viewing angles. Because each pixel can be turned on or off independently, OLED screens are ideal for dynamic visuals and are often preferred for high-quality images and videos on smartphones.
