Abstract

The invention provides a capacitive touch screen. The capacitive touch screen comprises an induction layer and a display panel. The capacitive touch screen further comprises a shielding layer. The shielding layer is arranged between the induction layer and the display panel. The shielding layer is an ultralow-resistance transparent conducting film. The visible light transmittance of the ultralow-resistance transparent conducting film ranges from 90% to 97%, the thickness is larger than 0 micrometer and smaller than 80 micrometers, and the sheet resistance value ranges from 0.01 ohm to 40 ohms. The sheet resistance value of the ultralow-resistance transparent conducting film ranges from 0.01 ohm to 8 ohms. The problem that in the prior art, a capacitive touch screen cannot simultaneously achieve the ultrathin purpose and the high signal-to-noise ratio is solved.

Description

Technical field [0001] The present invention relates to the field of electronic touch screens, in particular to a capacitive touch screen. Background technique [0002] The capacitive touch screen is a four-layer composite glass screen, which generally includes four layers from top to bottom: 1) substrate; 2) touch sensing layer; 3) OCA adhesive layer; 4) display panel. [0003] The capacitive touch screen is a touch screen technology that uses the current induction of the human body to work. Widely used in mobile phones, GPS, tablet computers and other electronic products, it is developing in the direction of large size, ultra-light and thin, high transparency and low manufacturing cost. However, in the development process of capacitive touch screens, some technical development bottlenecks are also encountered: first, it is difficult to drive and less sensitive; second, the process is complex, the yield is low, and the cost remains high; third, it is difficult to achieve super t...
