Abstract
The invention provides an outgoing line via overlap structure of a capacitive touch screen. A touch function area of the capacitive touch screen is in a single-layer structure. Vias of outgoing lines from an induction layer pattern are overlapped by the aid of an insulating layer and leads. Blank areas are preserved on the insulating layer at the overlap positions of the outgoing lines of the induction layer pattern and the leads. One blank area corresponds to the overlap of one outgoing line of the induction layer pattern and one lead. The leads and the outgoing lines of the induction layer pattern are disposed on two sides of the insulating layer respectively and are communicated by overlapping by the aid of the blank areas preserved on the insulating layer. The invention further provides a production method of the outgoing line via overlap structure. An induction layer and a drive layer of the touch function area are separated by the outgoing line via overlap, the number of the outgoing lines is reduced greatly, and the use of large-sized flexible circuit board solutions or multiple flexible circuit board solutions is avoided. The process difficulty in hot-pressing overlapping with the flexible circuit board is lowered, the yield is increased, the cost is lower, and the performances are not lowered.
