Abstract
The present invention provides a GF2 structure touch screen and a manufacturing technique thereof. The GF2 structure touch screen comprises a substrate layer having two opposite surfaces of a side A and a side B; and an exposure silver colloid layer, a transparent optical double-sided colloid layer, and a cover glass layer successively overlaid outwards from the side A; and a nano-silver layer is overlaid on the side B; or a nano-silver layer, a transparent optical double-sided colloid layer, and a cover glass layer successively overlaid outwards from the side A, and an exposure silver colloid layer is overlaid on the side B. According to the GF2 structure touch screen of the present invention, the nano-silver layer and the exposure silver colloid layer replace a current ITO conducting material, a line width may reach 2 micrometer or lower, low impedance and high transmittance of the touch screen are implemented when lighting and thinning of the touch screen is implemented, and optical performance of the touch screen is kept to be comparable to a current double-sided ITO touch screen.
Description
technical field [0001] The invention belongs to the technical field of touch screens, and in particular relates to a GF2 structure touch screen and a manufacturing process thereof. Background technique [0002] In the design and production process of mobile phones or notebooks / tablets and all human-machine touch screen interactive devices, thin-film touch screens are generally made by double-sided ITO technology. [0003] At present, the touch screen structure obtained by the traditional double-sided ITO indium tin oxide technology is as follows: figure 1 Shown: ITO layer 2, transparent optical double-sided adhesive layer 3, PET substrate layer 2, ITO layer 2, transparent optical double-sided adhesive layer 3, and cover glass layer 4 are sequentially stacked from one surface of PET substrate 1 outward . [0004] In the existing product structure, two layers of ITO conductive material and two layers of transparent optical double-sided adhesive are required. This kind of to...
