Abstract

The invention relates to a bridge type touch electrode, a manufacturing method thereof and a touch screen, wherein the bridge type touch electrode comprises a first conductive layer, a second conductive layer and a shadow elimination film layer, wherein at least one group of first electrode patterns and at least one group of second electrode patterns are arranged on the first conductive layer, each group of first electrode patterns comprises more than two first pattern units which are electrically connected with each other, and each group of second electrode patterns comprises more than two second pattern units which are spaced apart from each other; the second conductive layer comprises a connecting part and a body part; the shadow elimination film layer is clamped between the body partsof the first conductive layer and the second conductive layer, a via hole is formed in the shadow elimination film layer, the connecting part is located in the via hole, and the second pattern units are electrically connected with each other through the connecting part. According to the bridge type touch electrode, the manufacturing method of the bridge type touch electrode and the touch screen, the thickness of the shadow elimination film layer is small; a via hole is easy to form; the permeability of the via hole is good; and reliable bridging connection can be guaranteed. In addition, the shadow elimination film layer also has a visual anti-reflection function.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a bridge-type touch electrode, a manufacturing method thereof, and a touch screen. Background technique [0002] Currently, a single-layer indium tin oxide (Indium Tin Oxide, ITO) touch technology is used in the manufacture of touch screens due to its advantages of low cost and the ability to realize multi-touch. The so-called single-layer ITO touch sensor refers to a touch sensor formed by coating a layer of ITO on a glass or plastic substrate and etching the layer of ITO into a touch electrode. In this touch sensor, the ITO layer can be used as both a driving electrode and a sensing electrode, and the touch function can be realized without other film layers. The ITO layer is generally provided with an insulating layer and a conductive layer. The touch electrodes on the ITO layer, the insulating layer, and the conductive layer jointly form a bridge touch electrode. Vias a...
