Touch control screen and manufacturing method of touch control screen

Abstract

The invention relates to a touch control screen, which comprises a base plate, an indium tin oxide film and connecting conducting wires, wherein the indium tin oxide film is formed on the surface of the base plate; a plurality of first electrodes and a plurality of second electrodes in matrix arrangement are formed at the indium tin oxide film; the first electrodes and the second electrodes are in alternate arrangement; the first electrodes arranged in the same line in a first direction are mutually and electrically connected; the second electrodes arranged in the same line in a second direction crossed with the first direction are mutually separated and are electrically connected through the connecting conducting wires; and each connecting conducting wire is made of metal, and the surface of each connecting conducting wire is subjected to oxidation or vulcanization treatment. The invention also provides a manufacturing method of the touch control screen. The surfaces of the connecting conducting wires of the touch control screen are subjected to the oxidation or vulcanization treatment, so a layer of oxides or sulfides is produced on the surface of each connecting conducting wire; the reflectivity of the oxides or sulfides in the visible light wave band is lower, so the surface reflexivity of the connecting conducting wires can be reduced for reducing the visuality of the connecting conducting wires in strong light.

Description

technical field [0001] The invention relates to a touch screen, in particular to a touch screen with a single-layer indium tin oxide film 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 first electrodes and a plurality of second 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...
