Soft touch screen protective film

Abstract

The invention discloses a soft touch screen protective film. The protective film comprises a polyethylene terephthalate (PET) film layer, a supporting layer, a silica gel layer, a fluoride release film and a buffer layer; the supporting layer is attached to the bottom of the PET film layer; the silica gel layer is attached to the bottom of the supporting layer; one side, far away from the supportlayer, of the silica gel layer is connected with the buffer layer; and one side, far away from the silica gel layer, of the buffer layer is connected with the fluoride release film, wherein the thickness of the fluoride release film is 50 microns. The buffer layer comprises a first high-transparency PET film, a second high-transparency PET film and a third high-transparency PET film, wherein the first high-transparency PET film is attached to the bottom of the silica gel layer, the second high-transparency PET film is connected to the bottom of the first high-permeability PET film, and the third high-transparency PET film is connected to the bottom of the second high-permeability PET film. The soft touch screen protective film can well prevent a situation that bubbles is generated when thefilm is adhered to a mobile phone touch panel, so that adhesion is facilitated, and meanwhile, a situation that damage to a human bodies due to the fact that a conventional toughened glass film is easily broken is avoided.

Description

technical field [0001] The invention relates to the technical field of touch screen protective films, in particular to a soft touch screen protective film. Background technique [0002] With the development of society, the use of touch panels is becoming more and more common. Touch panels are mostly used for touch control of display devices. After long-term use, the surface of touch panels will have a certain degree of abrasion, resulting in poor touch effects. , so a layer of soft touch film is usually installed on the current touch panel. [0003] Existing touch film is generally directly composed of PET film and adhesive layer. After long-term use of this type of touch film, the friction on the surface of the PET film will also cause damage to the PET film, and it will also damage the touch screen if you do not pay attention. There are certain scratches on the surface of the panel, resulting in damage to the touch panel; [0004] In order to protect the touch panel in t...

[0002] With the development of society, the use of touch panels is becoming more and more common. Touch panels are mostly used for touch control of display devices. After long-term use, the surface of touch panels will have a certain degree of abrasion, resulting in poor touch effects. , so a layer of soft touch film is usually installed on the current touch panel

[0003] Existing touch film is generally directly composed of PET film and adhesive layer. After long-term use of this type of touch film, the friction on the surface of the PET film will also cause damage to the PET film, and it will also damage the touch screen if you do not pay attention. There are certain scratches on the surface of the panel, resulting in damage to the touch panel;

[0004] In order to protect the touch panel in the existing market, a glass film is usually installed. The tempered glass film has a certain hardness and has a certain explosion-proof performance in actual use. However, this type of tempered glass film is fragile in use and is easier to use. or cause harm, for this reason, we propose a soft touch screen protective film
