Micro-LEDs: Low-cost mass production within reach

In mid-May Leti presented a promising micro-LED fabrication technology at a conference in the United States. The technology would make it possible to fabricate micro-LEDs at a very low cost and transfer the LEDs onto all types of substrates—rigid, flexible, transparent, or opaque—with no limits on size. In the future, consumers could even order custom TV screens tailored to the size and layout of their living rooms! Here is how it works: Each pixel’s micro-LEDs are fabricated directly on the associated CMOS command circuit, eliminating the need to transfer the LEDs one by one onto TFT glass plates containing the command circuit—the only solution until now. Leti is seeking partners to scale the innovation up and commercialize it within the next four to five years.
