3D explosion-proof tempered glass film and application method thereof

Abstract

The invention discloses a 3D explosion-proof tempered glass film, comprising a tempered glass layer, an explosion-proof sticking layer and a release layer, wherein the tempered glass layer is arrangedon the upper surface of the explosion-proof sticking layer; the explosion-proof sticking layer is arranged on the upper surface of the release layer; an optical OCA layer is bonded between the tempered glass layer and the explosion-proof sticking layer; the explosion-proof sticking layer comprises a first explosion-proof layer and a second explosion-proof layer; and a silica gel layer is arrangedbetween the first explosion-proof layer and the second explosion-proof layer. The invention also provides an application method for the 3D explosion-proof tempered glass film. The 3D explosion-prooftempered glass film of the invention can fully attach onto and perfectly adhere onto the screen of a mobile phone, has scratch resistance, explosion resistance and high sensitivity to touch, and is capable of overally protecting the screen of the mobile phone. In addition, the explosion-proof sticking layer of the invention comprises two explosion-proof layers, i.e., the first explosion-proof layer and the second explosion-proof layer; when protection film is to be peeled off, the first explosion-proof layer is separated from the second explosion-proof layer, and the second explosion-proof layer can be easily peeled off from the screen of the mobile phone, so the 3D explosion-proof tempered glass film is convenient to use.

Description

technical field [0001] The invention relates to the field of protective films for electronic products, in particular to a 3D explosion-proof tempered glass film and a use method thereof. Background technique [0002] At present, with the development of the mobile phone industry, large-curved screens have become a major trend of mobile phone screens, and the materials of curved screens are not easily damaged. Existing information shows that large-curved screens use special plastic materials instead of mainstream glass materials, so they are more flexible than ordinary mobile phones; curved screens display clearly; curved screens are low in thickness, light in weight and low in power consumption. The AMOLED-active matrix organic light-emitting diode technology used in the screen is related to this kind of diode, which saves power, has low energy consumption, and supports curved display, which is very beneficial for smartphones to continue to become lighter, thinner, and have a...

Problems solved by technology

However, due to the limitation of its technology, the hot-bending 3D glass has a large tolerance between the glass and the screen of the mobile phone, so it cannot be fully adsorbed and bonded. The hollow structure in some positions seriously affects the tactile sensitivity; the full-glue glass on the market is small in size. The half-screen structure cannot fully protect the mobile phone, and the process requirements are very strict, the defect rate is high, and the cost is high. Moreover, many glass films on the market only have a single explosion-proof layer, which is easy to cause sticking and tearing problems.
