OLED is currently enjoying its time in the spotlight, but a similar display technology, Micro-LED, could be the next big thing: while both are self-emitting, the latter offers a longer lifespan than current OLED panels (no burn-in), is smaller (easier to produce higher-resolution panels in a compact form factor), and boasts very high response times in the nanosecond range.
Where micro-LEDs differ from OLED is in the makeup of their LED materials. The O in OLED stands for organic and refers to the organic materials used in light producing part of the pixel stack. Micro-LED technology changes this to an inorganic Gallium Nitride (GaN) material, which is typically found in regular LED lighting. This switch also reduces the need for a polarizing and encapsulation layer, making panels thinner. As a result, Micro-LED components are tiny, hence the name, measuring less than 100 µm. That’s less than the width of a human hair.
