An OLED display (Organic Light Emitting Diode) is a type of screen technology that uses organic compounds to produce light when an electric current is applied. 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, enhancing the overall picture quality. OLED displays are commonly used in various devices, including smartphones, televisions, and smartwatches. They are known for their thin design and flexibility, making them suitable for curved or foldable screens. Additionally, OLED technology is energy-efficient, especially when displaying darker images.
