Micro-LED Displays
MicroLED technology is a new type of display that aims to combine the best features of current LED and OLED screens, offering high brightness, contrast, and long life. These displays use very small LED chips as individual pixels, much smaller than those used in large outdoor screens. While MicroLEDs promise amazing picture quality, faster response times, and the ability to be foldable, they are currently very difficult and expensive to make. The main challenges are growing the tiny red and green LED chips consistently and efficiently, and then accurately placing millions of these chips onto a display panel at a high speed. Various methods for placing these chips are being explored, but none are perfect yet. Despite significant investment and some products appearing, MicroLEDs are still facing big manufacturing hurdles that prevent them from being widely available and affordable.
