MicroLED, also known as micro-LED, mLED or µLED, is an emerging display technology having pixel size of smaller than 50 µm. The LEDs are lifted off from the growth substrate and transfered onto the display substrate by mass transfer technology.

History

In 2000, Hongxing Jiang and Jing Li et al. published their study of electrical injection microLEDs based on InGaN semiconductors.[1][2][3][4]
