Problems solved by technology

[0002] The screen protective film sold in the existing market is difficult to fit the display screen during the film sticking process, and it is easy to generate air bubbles. For example, patent 200620137617.9 discloses a protective film replacement structure for LCD screens, which is used to replace a protective film. It includes a casing composed of a first casing and a second casing; a fixing plate fixed on the top side of the first casing, which has several vertical positioning parts; a liquid crystal module set on the top side of the fixing plate , which has a number of traversing positioning parts and a number of vertical positioning holes, the vertical positioning holes are used for the vertical positioning parts to pass through; , and can be displaced between an open position and a locked position, and it has a number of grooves for the traverse positioning parts to pass through, and the traverse positioning parts can be displaced along the grooves, so that the Two handles can drive the touch panel to move along the vertical positioning parts
The display window area of ​​the screen protector also has sticky glue, it is easy to absorb dust and other dirty substances, it is difficult to clean, and it is easy to scrap

Embodiment 1

[0026] The thickness of the white PET film is 0.03mm, the thickness of the transparent double-sided adhesive layer is 0.03mm, and the thickness of the PE film is 0.0475mm.

Embodiment 2

[0028] The thickness of the white PET film is 0.07mm, the thickness of the transparent double-sided adhesive layer is 0.07mm, and the thickness of the PE film is 0.0725mm.

Embodiment 3

[0030] The thickness of the white PET film is 0.05mm, the thickness of the transparent double-sided adhesive layer is 0.05mm, and the thickness of the PE film is 0.06mm.

[0031] The liquid crystal screen protective film of the present invention, because the screen display part does not contain any adhesive components, such as glue, only the non-display window area is glued for bonding with the screen, and no air bubbles will be generated when it is in contact with the screen, so it is very easy to bond ; The edge decoration part uses the color of the raw material itself as the background color, the printing effect is fuller and the color is more gorgeous. It can be applied to LCD screen protection films and decorative products of various high-end smart phones, handheld computers, tablet computers and other digital products.

Abstract

The invention discloses a liquid crystal screen protective film and a preparation method thereof. The liquid crystal screen protective film has a four-layer structure. Obverse and reverse sides of the liquid crystal screen protective film respectively are a transparent PET film and a frosted PET film. Two middle layers of the liquid crystal screen protective film respectively are a white PET film and a transparent double-faced adhesive tape layer. The white PET film is compounded between the transparent PET film and the transparent double-faced adhesive tape layer. The transparent double-faced adhesive tape layer is compounded between the white PET film and the frosted PET film. The liquid crystal screen protective film does not produce any bubbles when contacting with a screen and can be applied easily. The preparation method utilizes common film-preparation equipment, has simple processes and can be operated easily.
