发明名称 CAPACITIVE TOUCH-SENSITIVE DEVICE
摘要 A capacitive touch-sensitive device includes a sensor electrode layer, a signal trace layer, a flexible circuit board and an electrically-conductive adhesive layer. The sensor electrode layer includes electrically isolated sensor lines. The signal trace layer includes electrically isolated signal lines, each having an outer terminal portion coupled to a respective one of the sensor lines. The flexible circuit board has isolated mutually bonding pads, each corresponding to the outer terminal portion. The electrically-conductive adhesive layer includes a plurality of zones, each having a first adhesive matrix and first conductors dispersed therein. The first conductors bridge the outer terminal portion to the bonding pad.
