Abstract

The invention discloses a capacitive touch screen. The capacitive touch screen comprises a substrate component and a cover plate component, wherein the substrate component comprises a substrate; a SiO2 film is plated on the upper surface of the substrate, and a SiO2 film is plated on the lower surface of the substrate; a strip Mo-Al-Mo wire mesh electrode group is formed on each of the two SiO2 films; the two strip Mo-Al-Mo wire mesh electrode groups are mutually vertical; a passivation film is coated on each of the two strip Mo-Al-Mo wire mesh electrode groups; the cover plate component comprises a cover plate; a protective film is plated on the upper surface of the cover plate; an anti-reflection (AR) film is plated on the lower surface of the cover plate; an ink window is arranged around the anti-reflection (AR) film; and the lower surface of the cover plate is bonded with the upper surface of the cover plate. The capacitive touch screen has the advantages of simple manufacturing process and low production cost.

Description

technical field [0001] The invention relates to a touch screen, in particular to a capacitive touch screen. Background technique [0002] With the development of electronic technology and the advancement of information technology, the perfect combination of the two forms touch screen technology. According to the realization principle, touch screen technology can be divided into many kinds. The most commonly used are resistive touch screen and capacitive touch screen, among which capacitive touch screen is a new technology developed in recent years. The resistive touch screen is easy to manufacture, low cost, and easy to implement, making it the most widely used technology for early touch screens, and there are a large number of product applications in various fields. However, with the extensive use of resistive touch screens, defects such as poor surface wear resistance, poor light transmittance, inability to achieve precise positioning, poor positioning accuracy over time...
