Electrostatic capacity type touch screen panel and method for fabricating the same

Abstract

The invention relates to an electrostatic capacity type touch screen panel and a method for fabricating the same. The electrostatic capacity type touch screen panel comprises substrates with screen regions and passive regions; transparent electrode pattern parts formed by patterned transparent conducting layers in the screen regions of at least one side surfaces of the substrates respectively; external electrode lines patterned on the passive regions of at least one side surfaces of the substrates respectively, electrically connected with the transparent electrode pattern parts correspondingly, and provided with first to third metal layers which are stacked on the corresponding transparent conducting layers and made of NiCr alloy, conductive metal containing Cu, and NiCr alloy respectively. According to the touch screen panel and the method, the fabricating cost of a touch screen can be reduced effectively and the fabricating procedures for the touch screen panel can be greatly decreased. In addition, through a patterning technique of double-face exposure/etching, the precise alignment tolerance between the first and second transparent electrode pattern parts, between the first and second transparent electrode pattern parts and the first and second external electrode lines, and between the first and second external electrode lines can be maintained.

Problems solved by technology

[0010] First, it is difficult to maintain precise tolerances when patterning individual touchscreens followed by lamination

That is, signal-to-interference and aperture ratios can be increased by shifting, overlapping, etc.

[0011] Second, it is difficult to maintain precise alignment tolerances between ITO and outer electrode parts

That is, due to the screen printing (silver paste) operation through the external reference hole, it is difficult to control the process precisely, and due to the c
