Description

Technical Field

[0001] The utility model relates to a protective film, more specifically, to a multi-purpose display module protective film. Background Art

[0002] After the display module is attached to the cover plate, a protective film is attached to the cover plate, and then it flows to the QC position. When the QC personnel check the screen function, they need to put a PASS label (or NG label) on the protective film. The label attachment positions are not uniform, and there are many types of labels, which makes the display module surface messy and difficult to check. Secondly, the whole machine assembly and shipment also requires the display module protective film to be torn off and another whole machine protective film to be attached, which wastes materials and labor costs.

[0003] Chinese utility model patent document CN216890780U discloses a display module protective film, including a light release film, the front of which is fixedly connected to a protective film body, one side of which is fixedly connected to a tear handle, and a positioning hole is provided on the front of the tear handle. The number of the positioning holes is three, and the three positioning holes are distributed in an equilateral triangle. The protective film body includes a base film, and the front of the base film is fixedly connected to a functional film. The functional film is composed of six layers: a PET peeling layer, an anti-oil coating, an explosion-proof tempered layer, a blue light eye protection layer, a base film layer and an adhesive layer. The front of the base film is fixedly connected to an adhesive layer, and the material of the adhesive layer is electrostatic silicon ions. The front of the adhesive layer is fixedly connected to a base film layer, and the material of the base film layer is polyethylene terephthalate. The front of the base film layer is fixedly connected to a blue light eye protection layer, and the material of the blue light eye protection layer is an optical PET film. The front of the blue light eye protection layer is fixedly connected to an explosion-proof tempered layer, and the material of the explosion-proof tempered layer is thermoplastic polyurethane elastomer rubber. The front of the explosion-proof tempered layer is fixedly connected with an anti-oil coating, the material of which is butyl rubber and vinyl resin. The front of the anti-oil coating is fixedly connected with a PET peeling layer, the material of which is polyethylene terephthalate.

[0004] Obviously, the protective film in the patent is attached manually with a fixture, and the three circular positioning holes can be used for alignment. The three circular positioning holes are aligned with the positioning posts on the fixture to determine the relative position of the protective film and the module, which can quickly and accurately attach the protective film and adapt to the rhythm of the assembly line. It solves the problems of difficult and slow alignment of the protective film when attached manually, and repeated alignment of the offset attachment. At the same time, the circular positioning holes are designed on the tear handle to make full use of the original space of the protective film and avoid adding extra space and wasting materials. After the tear handle is aligned, the rest of the protective film is attached to effectively remove bubbles. However, this structure cannot solve the problem of attaching PASS labels on existing protective films. Utility Model Content
