Touch screen, electronic equipment including same and method for manufacturing same

Abstract

The invention relates to the technical field of touch screens, and in particular relates to a touch screen, electronic equipment including the same and a method for manufacturing the same. The touch screen comprises driving electrode layers, a transparent polymerization organic matter layer and a metal bridge, wherein the metal bridge is used for conducting two adjacent driving electrode layers; and a protective layer for covering the metal bridge and preventing oxidization of the metal bridge is arranged between the driving electrode layers and the metal bridge. According to the touch screen provided in the invention, as the protective layer covers the metal bridge, the metal bridge is not subjected to an oxidation reaction due to the contact of the metal bridge and a transparent polymerization organic matter, thus the conductivity of the metal bridge is effectively guaranteed, the impedance of an oxidation layer is avoided from increasing, and the yield of the touch screen is improved.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a touch screen, electronic equipment including the touch screen, and a manufacturing method of the touch screen. Background technique [0002] With the development and application of computer technology and various electronic devices, touch screens, as a human-computer interaction device, are increasingly used in various computers and various electronic devices. As the latest input device, the touch screen is currently the simplest, most convenient and natural way of human-computer interaction. With this technology, the user can operate the host by touching the icon or text on the touch screen with his finger, which makes the human-computer interaction more straightforward and greatly facilitates those users who do not understand computer operation. [0003] The wide application of touch screens has promoted the technical progress of touch screens at the same time, and has...

Problems solved by technology

[0004] The inventors of the present application found that in the current touch screen structure, the transparent polymeric organic layer is usually directly covered on the metal bridge, but since the transparent polymeric organic layer is exposed and developed to form holes after the post-baking process, the transparent polymeric organic layer The part of the hole close to the metal bridge will slip and react with the metal bridge to form a metal oxide layer with high impedance on the surface of the metal bridge. The metal oxide layer reduces or hinders the conductivity of the metal bridge, resulting in poor performance of touch screen products. degradation or malfunction
