Abstract

The utility model discloses an anti-drop metal bridge touch screen, which comprises: the substrate layer, one end face of substrate layer from top to bottom stacks gradually and sets up first figure layer, first protective layer, second figure layer, metal bridge body layer and second protective layer. According to the anti-drop metal bridge touch screen, the ITO layer is additionally manufactured after the OC layer, so that the ITO layer can be attached to the surface of the OC layer, and the contact area of the OC layer and the strong acid can be isolated because the wiring of the metal bridge body is acid etched by using phosphoric acid, nitric acid and acetic acid, so that the OC layer is protected, the adhesion of the OC layer is prevented from being poor, drop is avoided, and the contact area of the naked-leakage metal bridge body on the strong acid is further reduced.

Example 1

Referring to fig. 1 and 2, an anti-drop metal bridge touch screen 10 includes: the substrate layer 100, one end surface of the substrate layer 100 is sequentially laminated with a first pattern layer 110, a first protection layer 120, a second pattern layer 130, a metal bridge layer 140 and a second protection layer 150, preferably, the first protection layer 120 is an OC layer, and the second pattern layer 130 is an ITO layer.

It should be noted that, the second graphic layer 130 is disposed below the first protective layer 120, specifically, the first protective layer 120 is an OC layer, the second graphic layer 130 is an ITO layer, the ITO layer is an independent whole block, through isolation of the ITO layer, the OC layer is prevented from being in direct contact with the metal bridge layer 140, the metal bridge layer 140 is etched by strong acid, the OC layer is polyisoprene, and is not acid-proof, if the OC layer is in direct contact with the metal bridge layer 140 for a long time, the OC layer is corroded, so that the metal bridge layer 140 is exposed, and the metal bridge layer 140 is damaged.

In an embodiment, the second protection layer 150 is an OC layer, the metal bridge layer 140 is routed on top by strong acid etching, and the metal bridge layer 140 is not routed on bottom by strong acid etching, so that the provision of the second protection layer 150 as an OC layer can avoid the metal bridge layer 140 from directly contacting the substrate layer 100, and reduce the abrasion of the metal bridge layer 140.

In an embodiment, the first pattern layer 110 is an ITO layer, and the ITO layer has better conductivity, and meanwhile, the ITO layer has a light and thin property, so as to avoid blocking the sight of the user, and provide better touch feeling, and avoid breaking touch.

In another embodiment, the distance between the second pattern layer 110 and the metal bridge layer is 10 μm, and preferably, the distance between the second pattern layer 110 and the metal bridge layer 140 is 10 μm, which does not cause shielding of the line of sight, and the exposure accuracy of the yellow light process is 5 μm during the production and manufacture process.

Further, the base material layer 100 is a glass layer or a PET layer, and the glass layer and the PET layer have good light transmittance and stable properties, and do not react with other hierarchical structures.

Still further, the metal bridge layer 140 is any one of metal oxides of molybdenum, aluminum, and copper.
