COF is a key component for displays that transmits electric signals that drive each pixel on the panel. A display driver IC is mounted on the substrate to interconnect a display and a PCB.
Value proposition / Competitiveness
01Fine Pitch PatterningReducing the inner lead pitch of a driver IC (reduced chip size) and implementing multiple channels
02High flexibility and compact sizeRealizing a larger degree of freedom for connecting module components, and reducing the size of assembly areas
03High-resolution optical inspectionAutomatic precision inspection of micro-circuits
