OLED screens work through a unique technology that utilizes organic compounds to produce light. Unlike traditional LCD screens that require a backlight, OLED displays generate their own light, allowing for thinner and more flexible designs. Each pixel in an OLED screen is made up of organic materials that emit light when an electric current passes through them. This self-emissive property enables OLEDs to achieve true blacks and vibrant colors, making them a preferred choice for high-end applications in advertising and education.
