Abstract

A touch screen comprises a touch substrate, a protection substrate and a transparent optical cement layer. The touch substrate comprises a transparent base and a first conductive layer arranged on one side of the transparent base. The protection substrate comprises a panel body and a second conductive layer arranged on one side of the panel body. The transparent optical cement layer is arranged between the touch substrate and the side, where the second conductive layer is located, of the protection substrate. At least one of the first conductive layer and the second conductive layer comprises a cured transparent photosensitive resin matrix and conductive nanometer wires embedded into the cured transparent photosensitive resin matrix, and the conductive nanometer wires are connected in a staggered mode to form a conductive grid. The first conductive layer is patterned to form a plurality of first touch electrodes which are arranged in parallel at intervals and the first touch electrodes are respectively in the shape of a strip. The second conductive layer is patterned to form a plurality of second touch electrodes which are arranged in parallel at intervals, the second touch electrodes are respectively in the shape of a strip, and the first touch electrodes and the second touch electrodes are arranged perpendicularly. The touch screen has better conductive performance.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a touch screen. Background technique [0002] A touch screen is an inductive device that receives touch input signals. The touch screen has endowed information interaction with a new look and is a very attractive new information interaction device. The development of touch screen technology has aroused widespread concern in the information media circles at home and abroad, and has become a rising high-tech industry in the optoelectronic industry. [0003] The touch screen includes a touch substrate and a panel body stacked on the touch substrate. The traditional manufacturing method of touch substrate is usually as follows: [0004] (1) A conductive layer is formed directly on a transparent substrate. Taking an ITO (Indium Tin Oxide, indium tin oxide) conductive layer as an example, it is necessary to perform ITO coating first, and then perform patterning on the obtained ITO l...
