Zusammenfassung:A capacitive touch control device comprises transparent substrates, induction electrode layers, signal lead layers, flexible printed circuit boards and conductive resin layers, wherein the induction electrode layers and the signal lead layers are disposed on the transparent substrates, each induction electrode layer is provided with a plurality of induction circuits electrically isolated from one another, each signal lead layer is provided with a plurality of signal circuits electrically isolated from one another, and each signal circuit is provided with an outer end and connected with the corresponding induction circuit; each flexible printed circuit board is provided with a plurality of welding pads electrically isolated from one another; the conductive resin layers are disposed at the outer ends of the signal circuits and among the welding pads, each conductive resin layer is provided with a plurality of first blocks which are disposed at intervals and corresponds to the outer ends in position, each block is provided with a first resin body and a plurality of first conductors dispersed in the first resin body, and the first conductors of first blocks allow the outer ends of the signal lead layers to be correspondingly bonded with the welding pads of the flexible printed circuit boards. By the conductive resin layers, longitudinal electric breakover efficiency between the signal circuits and the flexible printed circuit boards can be increased effectively, and problems such as signal disconnection and instability are improved.
