Abstract

The invention discloses a manufacture method of a touch screen. The manufacture method comprises the following steps: forming a conducting layer on a substrate; etching the conducting layer to form a plurality of first electrodes and a plurality of second electrodes, wherein the first electrodes and the second electrodes are roughly arranged in a matrix way, are mutually insulated and are arranged at intervals; forming a plurality of insulating layers on the conducting layer, wherein each insulating layer covers the corners of two adjacent first electrodes arranged in the same row arranged along a first direction and the corners of two adjacent second electrodes arranged in the same line arranged in a second direction; and adopting an ink jet printing method to form a plurality of conducting rings which are mutually connected in series on the corresponding insulating layer. The invention also provides the touch screen which adopts the manufacture method. The manufacture method has the advantages of being simple in manufacture procedures and high in processing efficiency.

Description

technical field [0001] The invention relates to a touch screen, in particular to a touch screen with a single conductive layer and a manufacturing method thereof. Background technique [0002] Touch screens are widely used, and touch screens with a single-layer indium tin oxide (Single Indium Tin Oxide, SITO) structure have broader application prospects due to their thin thickness and low manufacturing cost. A SITO touch screen generally includes a substrate, and an indium tin oxide film formed on the substrate. The indium tin oxide film forms a plurality of first electrodes and a plurality of second electrodes roughly arranged in a matrix through etching and other methods. A plurality of second electrodes and a plurality of first electrodes are arranged at intervals. The plurality of first electrodes in the same row in the first direction are electrically connected. The plurality of second electrodes are insulated. In order to electrically connect the plurality of second ...
