Abstract
Abstract
This study presents a hybrid fabrication process for LED matrix on flexible multilayer printed circuit boards (PCBs). To prepare for the flexible PCB, a roll-to-roll screen printing process was developed to create a core circuit board by printing on both sides of the flexible substrate. From the core PCB, the lamination and etching processes are then used to form four layers in total. By using the proposed method, we successfully implemented the passive LED matrix display. This approach could be used for other applications that require flexible and multilayer circuits.
