Abstract
The present disclosure provides a flexible printed circuit board (FPCB), a method for manufacturing the FPCB, and a capacitive touch display device with the FPCB. The FPCB comprises an FPCB substrate and a common electrode voltage (VCOM) filter circuit arranged on the FPCB substrate. The FPCB further includes one or more filter units. the filter units comprises: a conduction layer, arranged on the FPCB substrate and electrically connected to a VCOM output end of the VCOM filter circuit; an isolation layer, arranged on the conduction layer; and a shielding film, which is grounded, arranged on the isolation layer and arranged parallel with the conduction layer.
