Micro LED display is a display technology that uses self-illuminating miniaturized LEDs as pixels.

Since the display houses self-emissive LEDs as its subpixels, it can express outstanding contrast ratio and vivid colors. Similar to OLEDs without a backlight and color filters, the display can have a lighter and slimmer design than LCD panel. Therefore, the structure of Micro LED display is relatively simple compared to LCDs and OLEDs.

Micro LED’s chips are so small as to require high-precision transfer technology, and chips are fabricated by processing ‘Epi wafer’. In the process, the wafer is cut into tiny pieces of chip units and transferred to an electrical circuit board. Thanks to bonding the micro-LEDs onto substrate end to end, micro LED display is open to all sizes and shapes.
