Description

Technical Field

[0001] The utility model relates to a touch screen component, more specifically, to a touch screen protective film component with an alignment mark. Background Art

[0002] The penetration rate of touch screens is very high, and social demand is increasing. When manufacturing touch screens, the process of film pasting often lacks suitable edges and corners as marking objects due to the irregular shape of the samples, which leads to a decrease in production efficiency.

[0003] Chinese utility model patent document CN219958201U discloses an OGS touch screen structure with alignment marks, including: OGS glass, a first protective blue film and an alignment mark, wherein the first protective blue film is arranged on one side of the OGS glass, the first protective blue film is provided with an air-avoiding hole, the first protective blue film is used to isolate and protect the OGS glass, the alignment mark is arranged on the OGS glass, and the alignment mark is located in the air-avoiding hole. In one embodiment, a BM ink layer is arranged on one side of the OGS glass, the BM ink layer is arranged around the four sides of the OGS glass, and the alignment mark is located on the BM ink layer. There are multiple alignment marks, each of which is located on the BM ink layer. There are also multiple air-avoiding holes, each of which is located in each air-avoiding hole. The air-avoiding hole is provided with a rounded corner. The structure also includes a second protective blue film, which is arranged on one side of the OGS glass away from the first protective blue film. A touch function layer is arranged on the OGS glass. The OGS touch screen structure with alignment marks also includes an FPC, which is connected to the touch function layer on the OGS glass. Obviously, the patent can realize the touch sensing function through the OGS glass by setting the OGS glass, the first protective blue film and the alignment mark; the first protective blue film is used to isolate and protect one side of the OGS glass to prevent foreign objects from damaging the touch sensing pattern on the OGS glass during the production process. This structure cannot solve the existing alignment problem when applying the film.

[0004] Chinese utility model patent document CN202711224U discloses an alignment structure of a capacitive touch screen, comprising: a cross alignment mark formed by two vertical alignment marks on a sensor layer; a flexible circuit board, wherein the flexible circuit board is provided with a notch at the intersection of the cross alignment mark and partially covers each alignment mark, and an alignment copper foil is provided at the position corresponding to the covering alignment mark. The notch is a through hole, and the intersection of the cross alignment mark is located in the through hole. The notch is a U-shaped opening, extending from an edge of the flexible circuit board to the intersection of the cross alignment mark, and the intersection of the cross alignment mark is located at the bottom of the U-shaped opening. The notch is a missing corner, and the intersection of the cross alignment mark is located in the missing corner. The alignment mark structure of the capacitive touch screen also includes an ink layer located between the front cover and the sensor layer, and the ink layer is connected to the front cover. The ink layer is a black ink layer.

[0005] Obviously, the flexible circuit board in the patent has a notch at the intersection of the cross alignment mark, and partially covers each alignment mark, and sets an alignment copper foil at the position corresponding to the covering alignment mark, so that when aligning from the direction facing the flexible circuit board, the flexible circuit board does not completely cover the cross alignment mark, and the intersection of the cross alignment mark can be directly seen, and the cross alignment mark and the alignment copper foil set at the position corresponding to the two alignment marks can be used to align from the direction facing the flexible circuit board. This alignment method is too complicated and cannot solve the existing alignment problem during film application. Utility Model Content
