Parallel adjustable grid eyeshield privacy protecting adhesive film

Abstract

The invention discloses a parallel adjustable grid eyeshield privacy protecting adhesive film which comprises a surface layer, a middle main film and a bottom layer. The surface layer is a polyethylene layer, the bottom layer is a polyethylene layer, and the middle main film comprises an upper layer, a middle layer and a lower layer, wherein the upper layer is a polyethylene terephthalate layer, the lower layer is a polyethylene terephthalate layer, and the middle layer is an active carbon fiber layer. The protecting adhesive film adopts a screen privacy dark technology and can prevent confidential information from being revealed and lead a screen to be only browsed by a front person, and other persons can only view a dark picture at both sides; a visual range of an LCD screen is limited in a certain range (preferably 60 degrees), the picture can be clearly viewed in the right side, but can not be viewed at both the left side and the right side, and the privacy performance is improved on the basis of original scratch, corrosion, glare and radiation resistance.

Problems solved by technology

[0003] At present, the use of LCD screen protectors has been popularized to most electronic digital products. For a long time, LCD screen protectors have been favored by the public for their high light transmittance, high definition, electrostatic attachment, scratch resistance and wear resistance. But at the same time, there are also great defects, that is, it is easy to glare, the anti-reflection effect is poor, the screen information is extremely poor in confidentiality, and the information is easy to be peeped, etc.

In order to solve these problems, corresponding anti-glare screen protectors have also appeared on the market, which can prevent glare from causing damage to human eyes. However, such screen protectors still cannot solve the disadvantage of extremely poor screen information confidentiality.
