Abstract
The utility model discloses a capacitive touch screen cover plate. The capacitive touch screen cover plate comprises a glass substrate and an ITO conducting layer, wherein a printing ink frame layer is arranged on the periphery between the glass substrate and the ITO conducting layer in a silk-screen mode, a window area is defined by the printing ink frame layer, and a silver paste layer is formed on the periphery of the bottom surface of the ITO conducting layer. According to the capacitive touch screen cover plate, the printing ink frame layer is arranged on the periphery between the glass substrate and the ITO conducting layer in the silk-screen mode, namely the printing ink frame layer is tightly attached to the bottom surface of the periphery of the glass substrate, the periphery of the ITO conducting layer is directly covered and blocked, the periphery of the ITO conducting layer cannot be seen from the outside, and therefore the printing ink frame layer just needs to achieve the blocking effect; the printing ink frame layer can contain printing ink in various colors and is not restricted by the colors of the printing ink, and therefore the application range of the capacitive touch screen cover plate produced through the OGS production technology is broadened.
