Today, let’s use the most Simple and easy to understand of the Method , guiding everyone to understand Micro-LED , and also The key technology that breaks the bottleneck for mass production 。

Micro-LED What is it?

Actually, don’t let its name scare you, Micro-LED Its core is particularly easy to understand: it simply takes what we usually see… LED The LED beads are engineered to an extreme miniaturization, so small that each individual chip can function as a standalone display pixel.

Its full name is Micro Light Emitting Diode , in Chinese it is called a micro light-emitting diode, and is often abbreviated as μLED Specifically, it involves replacing the conventional high-power LED , compressed to the micrometer scale level the size of —— How small is this size? It’s roughly the diameter of a human hair. 1/50 to 1/100 , the appearance of a single chip is completely invisible to the naked eye.

Compared with the screens we commonly use today, its structure is simpler and also more… “ Pure ”：

LCD Like “ Backlight + Blinds ” , prone to light leakage and impure black; OLED Is “ Organic small light bulb emits its own light ” , the picture quality is good but it is prone to aging and screen burn-in; whereas Micro-LED , is “ Countless ultra‑miniature inorganic LED Small light bulbs, neatly arranged in an array, emit light. ” It features no backlight panel and no liquid crystal layer; each tiny light bulb can be switched on or off independently, with individual brightness control, resulting in a simpler structure and even more exceptional performance.

Here, it is also necessary to distinguish a concept that is easily confused. — Mini-LED . Many people will associate it with Micro-LED Confusion arises because the fundamental difference between the two lies in chip size: Mini-LED The chip size is in 50-200 Microns, considered as… “ Advanced Backlight ” , at its core, it’s still auxiliary.
