Abstract

The invention relates to a touch screen and a method for manufacturing the same. The touch screen comprises a substrate, first electrodes, first peripheral wires, insulation layers, second electrodes and second peripheral wires and is further divided into a touch control region, a first peripheral region and a second peripheral region. The first electrodes comprise first main bodies and first contact pads, the first main bodies are positioned in the touch control region, the first contact pads are positioned in the first peripheral region, the first peripheral wires are arranged on the substrate and comprise first connecting pads, second connecting pads and first wires, the first connecting pads are connected with the first contact pads, the second peripheral wires are arranged on the substrate, are positioned in the second peripheral region and comprise third connecting pads, fourth connecting pads and second wires, the insulation layers correspond to the touch control region and the first peripheral region and are arranged on the substrate, the first electrodes, the first connecting pads and at least partial first wires, and the second electrodes are arranged on the insulation layers, are overlapped with the first electrodes in an insulation manner and are further connected with the third connecting pads.

Description

technical field [0001] The invention relates to a touch screen and a manufacturing method thereof. Background technique [0002] At present, touch screens have been widely used in display devices of various electronic products, so that users can control the actions of the electronic products by touch. In order to make the electrodes in the touch area of ​​the touch screen difficult to be recognized, indium tin oxide (Indium Tin Oxides, ITO) is usually used to form transparent touch electrodes. The touch screen generally includes a first electrode extending along a first direction and a A second electrode extending and insulated from overlapping the first electrode. [0003] In a touch screen with a single-layer conductive layer (Single ITO, also called SITO) structure, the first electrode and the second electrode are arranged on the same layer, but are insulated by an insulating layer at the intersection, wherein the second electrode The two parts of the electrode located ...
