Laser equipment maker Coherent says that its customer have expressed a "reasonable amount of interest " in its Micro-LED solutions. The company is taking orders for R&D tools, but it says that mass production of Micro-LED displays is "still years away".
Coherent offers several laser-based tools used to produce Micro-LED displays, including Laser Lift-Off equipment (LLO) used to separate micro-LEDs from the sapphire wafer and Laser Induced Forward Transfer (LIFT) used to move micro-LEDs from the donor to substrate.
Coherent is also a leader Excimer Laser Annealing (ELA) tools (used to fabricate LTPS backplanes). Coherent's laser tools can also be used to repair micro-LEDs and cut LED arrays.
