MicroLED displays are built on the foundation of self-emissive inorganic LEDs, acting as subpixels. These LEDs are usually in the micrometer range, without package nor substrate, and therefore are transferred in a way different from traditional pick & place techniques.
The key to Micro-LED’s success lies in its unique value propositions. Not only do these displays offer stunning visual clarity, high luminance, fast refresh rate, low power consumption, high dynamic range, and high contrast, but they also provide transparency, seamless connections, sensor integration, and the promise of an extended lifetime. Such features make Micro-LED a game-changer in the display industry.
While the disruption begins with Micro-LED, it does not end there. These displays not only meet the demands of existing applications but also create entirely new possibilities.
For the former, eight applications are addressed most: augmented/mixed reality (AR/MR), virtual reality (VR), large video displays, TVs and monitors, automotive displays, mobile phones, smartwatches and wearables, tablets, and laptops.
IDTechEx have recently observed a clear trend that most efforts are put on only a few applications such as large video displays/large TVs, Smartwatches/wearables, and augmented reality.
When talking about Mini-LED and Micro-LED, the LED size is a very common feature to distinguish the two. Both Mini-LED and Micro-LED are based on inorganic LEDs. As the names indicate, Mini-LEDs are considered as LEDs in the millimeter range, while Micro-LEDs are in the micrometer range. However, the distinction is not so strict in reality, and the definition may vary from person to person. However, it is commonly accepted that micro-LEDs are under 100 µm and even under 50 µm. While mini-LEDs are much larger.
When applied in the display industry, size is just one factor when talking about Mini-LED and Micro-LED displays. Another feature is the LED thickness and substrate. Mini-LEDs usually have a large thickness of over 100 µm, largely due to the existence of an LED substrate. While Micro-LEDs are usually substrateless, and therefore the finished LEDs are extremely thin.
A third feature that is used to distinguish the two is the mass transfer techniques that are utilized to handle the LEDs. Mini-LEDs usually adopt conventional pick-and-place techniques, including surface mounting technology. Every time, the number of LEDs that can be transferred is limited. For Micro-LEDs, millions of LEDs usually need to be transferred when a heterogenous target substrate is used; therefore, the number of LEDs to be transferred at a time is significantly larger, and thus, a disruptive mass transfer technique should be considered.
