A major bottleneck in the commercialization of Micro LED displays is the mass transfer of micron-size LEDs to a display backplane. Research by LEDinside, a division of TrendForce, reveals that many companies across industries worldwide have entered the Micro LED market and are in a race to develop methods for the mass transfer process. However, their solutions have yet to meet the standard for commercialization in terms of production output (in unit per hour, UPH), transfer yield and size of LED chips (i.e. Micro LED is technically defined as LEDs that are smaller than 100 microns).
Currently, entrants in the Micro LED market are working towards the mass transfer of LEDs sized around 150 microns. LEDinside anticipates that displays and projection modules featuring 150-micron LEDs will be available on the market as early as 2018. When the mass transfer for LEDs of this size matures, market entrants will then invest in processes for making smaller products.
