53‐4: Development of Particle‐Arrayed ACF for MicroLED

Anisotropic Conductive Film (ACF) is an adhesive film that provides three functions: adhesion, conduction, and insulation. It is used in many applications, including flat panel displays. Recently, we developed a new particle‐arrayed ACF specifically for Micro‐LED applications. This product ensures excellent contact resistance and high shear strength when bonding to small pads of the Micro‐LED. We also investigated the laser bonding process to improve production efficiency and pre‐cut ACF technology for transparent displays.
