G + G structure four-wire resistive touch screen

Abstract

The invention discloses a G + G structure four-wire resistive touch screen which comprises ITO conductive glass and a base layer which are sequentially arranged from top to bottom, an upper circuit layer and a lower circuit layer are arranged on the opposite faces of the ITO conductive glass and the base layer respectively, an upper silver wire is arranged on the upper circuit layer, and a lower silver wire is arranged on the lower circuit layer. Wherein the upper silver wire and the lower silver wire are connected through silver dispensing, and the upper silver wire and the lower silver wireat the joint are meshed with each other, so that the sum of the thicknesses of the upper silver wire and the lower silver wire at the joint is equal to the thickness of the upper silver wire or the lower silver wire at the non-joint; wherein an isolation layer is arranged between the upper circuit layer and the lower circuit layer, and a plurality of supporting points are arranged on the isolationlayer. Through the staggered meshing design of the connection points of the upper silver wires and the lower silver wires needing to be connected through silver dispensing, the total thickness is reduced to the thickness of one layer, the operation force of the touch screen is reduced to 120 g or below, and the touch experience feeling of a user is greatly improved.

Description

technical field [0001] The invention relates to the technical field of touch screen manufacturing, in particular to a G+G structure four-wire resistive touch screen. Background technique [0002] The upper circuit of the ordinary F+G structure four-wire resistive touch screen uses ITO conductive film. As the touch layer, because of its soft material, the operating force of the touch screen can reach ≤50g, which can fully meet the requirements of customers with an operating force of ≤120g. , but the upper circuit (touch layer) of the four-wire resistive touch screen with G+G structure uses ITO conductive glass. Since the thinnest ITO glass available on the market is 0.2mm, its material is hard and its curvature is much smaller than The ITO conductive film is small, so the operating force required for touch is generally ≥180g, which limits the promotion and application of the G+G structure four-wire resistive touch screen, and measures must be taken to reduce the operating for...
