Description

Technical Field

[0001] The utility model relates to the technical field of touch screens, and in particular to an anti-static touch module and an electronic device. Background Art

[0002] Static electricity often causes great harm to electronic products such as touch screens, so it is very necessary to improve the anti-static ability of the touch module during the production process. In OGS touch screens, the conventionally designed OGS touch screens will add static cones around the wiring to prevent static electricity from damaging the touch screen, but this layer of static cone protection is not enough to achieve a good anti-static effect. According to the conventional design, in order to make the touch screen GND and the screen assembly GND have better common grounding ability, the GND leakage copper of the FPC of the two is usually connected to the common ground through the client motherboard, but when the two are not connected, their GND is in a suspended state, which will cause the touch module to be easily damaged by static electricity during production.

[0031] The touch cover plate 100 includes a transparent substrate 110, a silk screen ink layer 120, a touch function layer 130, a metal wiring layer 140 and an insulating ink layer 150 which are sequentially arranged from bottom to top;

[0032] The silk-screen ink layer 120 and the metal wiring layer 140 are both disposed in the non-display area 1 of the touch cover 100;

[0033] The metal wiring layer 140 includes a GND 141 and a binding point 142;

[0039] The touch function layer 130 is arranged in the display area 2 of the touch cover. The first ITO layer 131 is an ITO bridge point structure in the touch module; the second ITO layer 133 is an ITO pattern layer in the touch module; the first OC insulating layer 132 is used to isolate the first ITO layer 131 and the second ITO layer 133, that is, to isolate the overlapping part of the ITO bridge point structure and the ITO pattern layer to avoid short circuit between the two. In addition, the first OC insulating layer 132 only partially covers the first ITO layer 131, so that the first ITO layer 131 can still connect to the sensing channel or driving channel on the second ITO layer 133; the metal wiring layer 140 can be connected and conducted with the second ITO layer 133.

The double-layer ink superposition method can prevent the metal wiring layer from being observed through the silk screen ink layer.

[0042] As a preferred embodiment of the present invention, a shadow elimination layer is further provided between the silk screen ink layer 120 and the touch function layer 130. The provision of the shadow elimination layer can greatly avoid poor display phenomena, such as the shadow problem caused by the transparent substrate, the first ITO layer or the second ITO layer, and improve the quality and display effect of the touch module.

[0043] As a preferred embodiment of the present invention, an AR coating layer is further provided between the silk-screen ink layer 120 and the transparent substrate. In the embodiment of the present invention, vacuum sputtering coating can be performed on the transparent substrate to coat a layer of niobium oxide as an oxide film layer for eliminating etching lines, thereby forming an AR coating layer, thereby eliminating etching lines and improving the display quality of the touch module.

[0044] As a preferred embodiment of the present invention, the transparent substrate is tempered glass, thereby improving the strength of the touch display screen.

[0045] As a preferred embodiment of the present invention, one or more of an anti-peep film layer, an AG film layer or an AF film layer is provided on the side of the transparent substrate away from the silk-screen ink layer 120.
