Problems solved by technology

The preparation of the traditional ITO layer is generally to plate ITO on the glass, and obtain the required induction lines in the X and Y directions after etching. This traditional production process is complex and lengthy, and this production method inevitably requires engraving If the etching process is used, a large amount of ITO materials will be wasted, further increasing the manufacturing cost, making the price of the touch screen higher, resulting in a higher price of touch electronic products

Abstract

The invention relates to a touch screen. The touch screen comprises a glass panel and an induction module which is arranged on the glass panel in a laminating mode; the induction module comprises a first conducting layer which is arranged on the glass panel; the first conducting layer comprises a first conducting electrode which is made of UV (Ultra Violet) type photoreceptive nanometer conducting materials and a plurality of first conducting bridges which are arranged on the first conducting electrode. According to the touch screen, the first conducting layer is made of the UV type photoreceptive nanometer conducting materials, UV type photoreceptive nanometer conducting ink coats the glass panel in a coating mode, then the first conducting electrode is produced in an exposure developing mode, finally silver paste prints the first conducting electrode to produce the plurality of first conducting bridges, the etching technology is saved due to the fact that ITO is replaced by UV type photoreceptive nanometer conducting materials, the production technology is simple, the production costs are low, and accordingly the price of the touch screen is low and reduction of the price of a touch electronic product is facilitated.

Description

technical field [0001] The invention relates to the technical field of touch, in particular to a touch screen. Background technique [0002] With the rapid development of the TP (TOUCPANEL) industry, there is an increasing demand for transparent conductive materials, but since the transparent conductive material commonly used in touch screens is indium tin oxide (ITO), the indium element in ITO is a rare and precious metal. Relative lack and high price make the price of touch electronic products higher. Therefore, it is urgent to find a new transparent conductive material to replace indium tin oxide (ITO), so as to reduce the price of touch electronic products. [0003] At present, ITO coating and ITO patterning are generally required to prepare touch screen electrodes with ITO. The preparation of the traditional ITO layer is generally to plate ITO on the glass, and obtain the required induction lines in the X and Y directions after etching. This traditional production pro...
