We have developed a high-precision mass transfer technology for micro-LED displays utilizing self-alignment with wall structures. By optimizing the spacer design, we achieved high-precision mounting of μLEDs and Micro-ICs without relying on equipment accuracy. This technology facilitates the creation of transparent flexible displays without requiring TFTs, offering high-brightness and high-reliability, particularly for automotive applications.
