The antireflection layer 2 is a film for reducing reflection of light and increasing light transmittance, and may be formed of Nb2O5Material layer and SiO2The material layers are laminated, and the antireflection layer 2 may be disposed on the first surface of the glass layer 1 by physical vapor deposition, for example, by magnetron sputtering. The first film layer 3 needs to be made of Nb2O5Layer and SiO2Laminated layers, and note that Nb2O5The layer must be bonded to the second surface of glass layer 1, SiO2The layer must be bonded to the sensing layer 4; wherein, the above Nb2O5The bonding between the layer and the glass layer 1 can be achieved by directly depositing Nb by vapor deposition2O5The layer is arranged on the second surface of the glass layer 1, namely in the specific production, Nb is firstly magnetron sputtered on the second surface of the glass layer 12O5Layer, then magnetron sputtering of SiO2Layer, followed by the sensor layer 4 and SiO2Layer bonding; the arrangement of the sensing layer 4 can be performed by referring to the technical means in the prior art, and will not be described in detail here. The SiOxNy layer 5 is the outermost layer of the touch module and is a layer used for being connected with the liquid crystal display module, the arrangement of the SiOxNy layer 5 can effectively improve the transmittance of light rays emitted by the liquid crystal display module, reduce the refraction of the light rays and ensure the light ray amount entering the touch module.

Further, as shown in fig. 2, in order to match the antireflection layer 2, the first film layer 3 and the SiOxNy layer 5, and to achieve the best light transmission effect of the antireflection layer 2, the first Nb may be used2O5The thickness of the layer 21 is set to be in the range of 8-18nm, and the first SiO is applied2The thickness of the layer 22 is set in the range of 26-36nm, the second Nb2O5The thickness of the layer 23 is set to be in the range of 105-115nm, the second SiO2The thickness of layer 24 is set to be in the range of 80-90 nm. Wherein, in order to realize the best projection effect and the minimum refractive index, the first Nb is simulated by the Michelson optical simulation software2O5The optimum thickness of layer 21 is 13nm, the first SiO2The optimum thickness of layer 22 is 31nm, the second Nb2O5The optimum thickness of layer 23 is 110nm, the second SiO2The optimum thickness of layer 24 is 85 nm.

Furthermore, when the electronic device provided by the invention uses the OGS touch screen provided by the second embodiment, the electronic device can have a better display effect, and the use requirements for the electronic device can be met.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modification, equivalent change and modification made to the above embodiment according to the technical spirit of the present invention are still within the scope of the technical solution of the present invention.
