Description

Technical Field

[0001] The utility model relates to a touch screen, more specifically, to a touch screen with a viewing area protection film attached correction structure. Background Art

[0002] Currently, some TP products require double-sided foam to be attached to the edge of the sensor for assembly of the housing. In order to ensure the assembly strength, the width of the foam will be increased, which will easily lead to a small distance between the foam and the viewing area. Usually, a finished product protective film is generally attached to the viewing area to protect the cleanliness of the product. The specific film attachment process is: first attach the viewing area protective film on the back, and then attach the foam (attaching the foam first will affect the cleaning effect of the product). Since the gap between the double-sided adhesive and the viewing area is very small, it is easy to cause the viewing area protective film to be attached sideways. Therefore, when attaching the foam, the viewing area protective film will be covered by the foam, affecting the quality of the product.

[0003] Chinese invention patent document CN103793119A discloses a capacitive touch screen cover, comprising a glass substrate and an ITO conductive layer. An ink frame layer is screen-printed around the periphery between the glass substrate and the ITO conductive layer, and the ink frame layer encloses a window area. A silver paste layer is formed around the bottom surface of the ITO conductive layer, and the silver paste layer corresponds to being directly below the ink frame layer. An insulating layer is formed on the bottom surface of the silver paste layer. A first protective film is arranged between the ITO conductive layer and the silver paste layer. A second protective film is arranged on the bottom surface of the insulating layer. The ink frame layer is a white ink frame layer. The capacitive touch screen cover is provided with a functional hole, and the glass substrate is rectangular, and the four corners of the glass substrate are all rounded. The cover is also provided with a flexible circuit board for electrically connecting a control circuit board of an electronic product. The present invention also provides a production process for a capacitive touch screen cover plate, comprising the following steps: step a: screen printing ink around the bottom surface of a glass substrate to form an ink frame layer, wherein the ink frame layer surrounds a window area; step b: plating a layer of ITO conductive film on the bottom surface of the ink frame layer, wherein the ITO conductive film covers the ink frame layer and the window area; step c: etching the ITO conductive film to form an ITO conductive layer; step d: plating a layer of protective film around the bottom surface of the ITO conductive layer to form a first protective film; step e: screen printing silver paste on the bottom surface of the first protective film to form a silver paste layer; step f: screen printing insulating material on the bottom surface of the silver paste layer to form an insulating layer; step g: plating a layer of protective film on the bottom surface of the insulating layer to form a second protective film.

[0004] Obviously, the patent has an ink frame layer printed on the periphery between the glass substrate and the ITO conductive layer to obtain a shielding effect. This structure cannot solve the problem of the existing viewing area protection film being pasted off-center.

[0005] Chinese utility model patent document CN204595806U discloses a protective film, which is applied to a touch screen to protect a touch sensing layer. The touch screen has a visible area and a non-visible area located outside the visible area. The protective film includes: a first substrate; an adhesive layer formed on the first substrate, the adhesive layer corresponding to the visible area and the non-visible area of ​​the touch screen respectively having a first adhesive area and a second adhesive area, the adhesive layer being used to bond with the touch sensing layer of the touch screen; a second substrate formed on the adhesive layer and blocking the first adhesive area of ​​the adhesive layer; and a release film formed on the second substrate. The second substrate exposes the second adhesive area of ​​the adhesive layer, and the release film is directly in contact with the second adhesive area of ​​the adhesive layer. The protective film also includes an auxiliary substrate arranged outside the second substrate, the auxiliary substrate corresponds to the second adhesive area of ​​the adhesive layer, and the auxiliary substrate and the second substrate separate the release film from the adhesive layer. The protective film also includes another adhesive layer formed between the first substrate and the adhesive layer. The shape profiles of the first substrate, the adhesive layer and the release film are consistent. The patent also discloses a touch screen, which has a visible area and a non-visible area located outside the visible area. The touch screen includes a touch sensing layer and a protective film bonded to the touch sensing layer. The protective film includes a first substrate, a glue layer, and a second substrate arranged in sequence. The glue layer has a first glue area and a second glue area corresponding to the visible area and the non-visible area of ​​the touch screen, respectively. The second glue area is bonded to the touch sensing layer, and the second substrate is located between the first glue area of ​​the glue layer and the touch sensing layer. The touch sensing layer includes a substrate and a sensing electrode layer arranged on one surface of the substrate. The second glue area is bonded to the other surface of the substrate of the touch sensing layer, and the second substrate is located between the first glue area of ​​the glue layer and the substrate of the touch sensing layer. The touch screen also includes a protective cover plate and a transparent optical glue layer bonding the protective cover plate and the touch sensing layer. The touch screen also includes a light shielding layer arranged between the protective cover plate and the transparent optical glue layer, and the area where the light shielding layer is located constitutes the non-visible area of ​​the touch screen. The protective film also includes another glue layer formed between the first substrate and the glue layer.

[0006] Obviously, in this patent, the second substrate of the protective film is used to isolate the adhesive layer of the protective film from the touch sensing layer. Even if the thickness of the touch sensing layer is small, the appearance of the touch sensing layer will not be affected by the viscosity of the protective film. This structure also solves the problem of the existing visual area protective film being pasted unevenly. Utility Model Content

[0029] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0030] As described in the background technology, for touch screens, some TP (TP, i.e., touch screen) products in the prior art need to stick double-sided foam on the edge of the sensor for assembly of the casing. In order to ensure the assembly strength, the width of the foam will be increased, which will easily lead to a very small distance between the foam and the viewing area. Usually, a finished product protective film is generally pasted on the viewing area to protect the cleanliness of the product. The specific film pasting process is: first paste the viewing area protective film on the back, and then paste the foam (pasting the foam first will affect the cleaning effect of the product). Since the gap between the double-sided adhesive and the viewing area is very small, it is easy to cause the viewing area protective film to be pasted off-center. Therefore, when pasting the foam, the viewing area protective film will be covered by the foam, affecting the quality of the product.

[0031] In order to solve this technical problem, the utility model provides a touch screen 1 with a viewing area protection film attachment correction structure, comprising a touch screen body 10, a rectangular viewing area 11 is provided in the middle of the touch screen body 10, an attachment area 12 is provided on the periphery of the viewing area 11, a fitting alignment line 121 is provided on the outer edge of the attachment area 12, and an alignment reference mark 2 is provided on the four corners of the attachment area 12. The outer edge of the fitting alignment line 121 coincides with the inner edge of the alignment reference mark 2. The fitting alignment line 121 is in the shape of a square. The alignment reference mark 2 is in the shape of an "L".

[0032] With the above structural design, when attaching the foam to the back of the touch screen, the worker can refer to the four "L"-shaped alignment reference marks 2 and align the four corners of the viewing area protective film to be attached with the four "L"-shaped alignment reference marks 2, thereby effectively improving the attachment accuracy of the viewing area protective film, preventing the viewing area protective film from being attached skewed, and facilitating the subsequent foam attachment operation. Since the alignment reference mark 2 is screen-printed together with the bonding alignment line 121, only the mesh needs to be changed, and the process will not be increased.
