Abstract

The invention provides conductive film and a metal grid touch sensor. The conductive film comprises a substrate composed of a substrate body and a flexible connecting part, and a conductive layer including a plurality of first conductive wires, a plurality of second conductive wires, first isolating conductive wires and second isolating conductive wires, wherein the conductive layer is arranged onone surface of the substrate body. In an edge wiring area of the conductive layer, the first isolating conductive wires and the second isolating conductive wires are located on the inner sides of thepulled first conductive wires and the inner sides of the pulled second conductive wires and laid in the converging wiring directions of the pulled first conductive wires or laid in the converging wiring directions of the pulled second conductive wires. The conductive film is stabler in touch control signal and higher in touch control sensitivity and precision and shields clutter influences aroundthe exterior.

Description

technical field [0001] The invention relates to the technical field of touch control, in particular to a metal-mesh-based conductive film and a metal-mesh touch sensor. Background technique [0002] The conductive film has both high conductivity and good light transmission, and has a wide range of application prospects. In recent years, it has been successfully applied in liquid crystal displays, touch panels, electromagnetic wave protection, transparent electrode transparent surface heaters for solar cells, and flexible light-emitting devices. [0003] In the field of touch screen technology, the transparent conductive film is usually used as a sensing element for sensing input signals such as touch. Generally, the transparent conductive film includes a transparent substrate and a conductive layer disposed on the transparent substrate. Currently, indium tin oxide (Indium TinOxides, ITO) is the main material of the conductive layer in the transparent conductive film. [0...
