QLED, OLED, Mini-LED, what does it all mean? Not all modern TVs are created equal. TV technology demystified and explained. The difference comes down to how each TV creates light: Mini-LED sets use thousands of much smaller LEDs behind the panel to create more dimming zones, while OLED panels light each pixel individually for deeper blacks and a wider colour range without a backlight. If you're comparing TV display technologies before you buy, this quick guide breaks down what LED means, how QLED, OLED, and Mini-LED differ, and which type is likely to suit your room, viewing habits, and budget best.
