The display industry is coming to a major turning-point due to high demand and unprecedented requirements of power efficiency and brightness driven by next-generation information displays, automotive, VR/AR, and IoT applications.  MicroLED technology is currently the only way for that transformation.

There are numerous obstacles in realizing a good quality, high yield, mass-production-ready micro-LED display. Poor efficiency at low current densities and variation of emission level between chips is one of the key issues that is directly related to the quality of the sidewalls of the chips and the high surface recombination effects. These effects become more prominent as the chip size gets smaller.
