By arranging the antibacterial anti-fingerprint layer 100 on the upper surface of the glass substrate 200, the surface of the OGS touch screen has the antibacterial function and the anti-fingerprint function at the same time, so that after the surface of the touch screen is frequently contacted with the skin of a user, the surface of the touch screen can be prevented from breeding a large amount of bacteria and residual viruses, the potential threat to the health of the user is avoided, and meanwhile, the surface of the touch screen can be prevented from being stained with greasy dirt and fingerprints, and the influence on the appearance and the display effect of the touch screen caused by the dirty appearance of the touch screen is avoided; specifically, in this embodiment, the antibacterial anti-fingerprint layer 100 is an antibacterial anti-fingerprint drug layer, the antibacterial anti-fingerprint drug layer includes a silver-zinc composite antibacterial material and a fluorine-containing organic anti-fingerprint solution, wherein the silver-zinc composite antibacterial material has an antibacterial effect, specifically, silver ions and zinc ions are loaded on a silica carrier in the form of silver oxide and zinc oxide, then the silica carrier containing the silver-zinc ions is subjected to silane derivative surface treatment and cyclodextrin is wrapped, so as to obtain a silver-zinc composite antibacterial material wrapped with cyclodextrin, the silver-zinc composite antibacterial material has a better adsorption performance and can have an excellent antibacterial effect, and the antibacterial principle of the silver-zinc composite antibacterial material is as follows: under the environment of certain humidity, silver ions and zinc ions can be moderately released from silver oxide and zinc ions, so that the silver oxide and zinc ions can cause damage to bacterial cell walls and cell membranes, enter cells, react with biological groups such as protease, DNA and the like in the cells, and cause denaturation and inactivation of the biological groups, thereby achieving the aim of inhibiting and killing microorganisms; the fluorine-containing organic anti-fingerprint solution is an organic solution with active silane groups and fluorine-containing modified organic groups, and can achieve a better anti-fingerprint effect.
Further, the first ink layer 300 is disposed around the periphery of the visual area, and in this embodiment, the first ink layer 300 is a black ink layer, so that the first ink layer forms a frame of the OGS touch screen structure, and the black frame formed by the first ink layer 300 can play a role in shading and decoration, so that the metal wiring layer in the touch Sensor structure 500 can be prevented from being seen by naked eyes, and preferably, the thickness of the first ink layer 300 is 1-2.5 μm. In addition, the IM layer 400 plays a role in eliminating shadows, specifically, since the ITO Bridge layer and the ITO layer in the touch sensor structure 500 can form visual contrast with other areas, the IM layer 400 can reduce contrast, so that the ITO Bridge layer and the ITO layer fade under ambient light, and shadow elimination is realized, so that human eyes are prevented from being aware of the ITO Bridge layer and the ITO layer in the touch sensor structure 500. Further, by plating the SIO2 layer 600 on a side of the touch sensor structure 500 away from the glass substrate 200, that is, by covering the entire surface of the SIO2 layer 600 with the touch sensor structure 500, external foreign matters are prevented from directly contacting the touch sensor structure, so that the touch function of the touch sensor structure 600 is damaged, but when plating the SIO2 layer 600, binding sites on the touch sensor structure 600 need to be avoided, and preferably the thickness of the SIO2 layer is 40nm.
