Projected capacitive touch screen panel with single-layer indium tin compound electrode

2012 
The invention discloses a projected capacitive touch screen panel with a single-layer indium tin compound electrode, comprising a first protective layer, an indium tin compound electrode layer and a second protective layer, wherein the indium tin compound electrode layer consists of a plurality of basic units; each basic unit comprises an interdigital type induction region and two driving electrode wiring channels; the interdigital type induction region comprises an induction electrode and a driving electrode which are arranged in an interdigital way. Compared with the prior art, the projected capacitive touch screen panel with the single-layer indium tin compound electrode has the indium tin compound electrode layer, the induction electrode and the driving electrode of the indium tin compound electrode layer are located on the same ITO (Indium Tin Oxide) layer, thus the process complexity is lowered; and as the induction electrode and the driving electrode are not overlapped on the same layer, the bridging process in the traditional touch screen panel is not needed, the manufacturing cost is saved, and the problem of the raising reject ratio of the touch screen panel caused by breakage of a metal connection bridge is avoided. Meanwhile the invention discloses a projected capacitive touch screen.
