The adhesive layer is adhered to the display screen of the preset electronic device (such as the panel of the smart phone or the touch screen of the tablet), and then the second tear film is peeled off for the scratch-resistant layer to be formed on the surface of the opposite display screen. The scratch layer has a scratch-resistant effect, so that the scratch-resistant layer can form a protective effect on the surface of the display screen for external objects (such as fingers, stylus or carry-on coins, keys, etc.) to contact and slide on the display screen surface. When moving, pressing or touching, it can reduce the damage caused by scratches or streaks caused by external object pressing or rubbing, and maintain the integrity of the display screen, so that the user can smoothly touch the display screen.

The secondary purpose of this creation is that the electronic device protection sticker is provided with a scratch-resistant inner layer made of polyethylene terephthalate (PET) on the scratch-resistant layer, and the upper and lower surfaces of the inner layer of the scratch-proof inner layer. There is a glass layer made of polymethyl methacrylate (PMMA resin, also known as acrylic) mixed with bismuth (Si), so that the scratch-resistant layer has a transmittance of 91% or more and produces 7 The surface hardness of 9H (Hardness), so that the scratch-resistant layer is not easily damaged by scratches or streaks caused by contact or rubbing of fingers, stylus or external objects such as coins or keys, to maintain the integrity of the display screen. And enable the user to smoothly touch the display screen.
