Problems solved by technology

The traditional Metal Mesh-based touch screen is connected by a conductive bridge, and its conductive material area occupies about 5% to 10% of the entire electrode area. Therefore, the contact area at both ends of the conductive bridge is small, which may easily cause high connection impedance or risk of open circuit

Abstract

The invention discloses a touch screen and a display screen. The touch screen comprises a substrate, a first electric conduction layer, an insulation layer and a second electric conduction layer, wherein the first electric conduction layer is positioned on the surface of the substrate and comprises a first metal electrode and a second metal electrode, and the first metal electrode and the second metal electrode are mutually insulated; the second metal electrode comprises two first sub-patterns which are independently arranged on two sides of the first metal electrode; the insulation layer is arranged on the first electric conduction layer; the second electric conduction layer is arranged on the first electric conduction layer and the insulation layer and comprises a third metal electrode;the third metal electrode is connected with two first sub-patterns through the insulation layer; a first sub-pattern in the first metal electrode and the second metal electrode form a touch driving electrode; and the other first sub-pattern forms a touch induction electrode. Through the above way, impedance can be effectively lowered, and a risk of open circuit is reduced.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a touch screen and a display panel. Background technique [0002] With the rapid development of flexible display OLED technology, the matching touch screen is also required to be flexible and foldable. The traditional touch screen is made of ITO, but ITO is made of brittle metal oxide, which can no longer meet the requirements of flexible touch. Require. [0003] Metal Mesh (metal grid) is very suitable for application on flexible touch screens due to its good flexibility. Traditional Metal Mesh-based touch screens are connected by conductive bridges. The conductive material area occupies about 5% to 10% of the entire electrode area. Therefore, the contact area at both ends of the conductive bridge is small, which may easily cause high connection impedance or risk of open circuit. Contents of the invention [0004] The main purpose of the present invention is to provide a touch s...
