Product description

Chip-on-flm or COF is a substrate manufactured by mounting semiconductor chips directly on a thin film printed circuit board (PCB). It serves to transmit electrical signals to a display panel.

It is the ideal material for the next generation of flexible and wearable displays, such as that of smartphones with a thin and narrow bezel.
