iode) An LED display technology that uses very small pixels. Also known as "mLED" and "µLED," MicroLED is a true LED emitter like OLED and plasma rather than the backlight source in an LCD/LED TV. Modular wall-sized MicroLED displays were demonstrated by LG and Samsung in 2018 that were made up of several square modules that fit together. In 2019, Samsung introduced a 75" MicroLED TV. Mass production for MicroLED-based TVs, phones, watches and microdisplays is expected in the 2021-2024 time frame. See LED

Color Emitters vs. Backlighting
No larger than 100 µm, MicroLEDs directly emit colors. In contrast, regular LEDs and MiniLEDs 100 to 300 µm in size are used as backlights. MiniLEDs provide greater dimming precision. (Image courtesy of Ron Mertens.)
