Abstract
The invention discloses a side view prevention PET (polyethylene glycol terephthalate) protective membrane which comprises a PET release membrane, a glue layer, a PET original membrane and a polarizer; the glue layer is coated on the PET release membrane; the polarizer is coated on the glue layer; and the PET original membrane is coated on the polarizer. Through the mode, computer and cell phone users can not be restricted by occasions and can work freely; and the screen seen by people beside and around is completely black, thus business secret and personnel privacy are protected effectively.
Description
Technical field
The present invention relates to a kind of PET diaphragm, particularly relate to a kind of anti-side-looking PET diaphragm.
Background technology
Development along with society; novel high-end electronic product goes on the market in succession; its protectiveness requires more and more higher; particularly electronic display in use needs special protection; use in the market notebook computer; the LCDs visible angle of mobile phone is all very large; this gives senior business people; the Senior Consultant on Education; financial quarters's occurrences in human life and lawyer are in meeting; public arena or office during the journey bring larger puzzlement, because the personnel on every side of reaching can see the particular content among the screen very easily clearly, cause information leakage to cause huge commercial loss at one's side.
Existing PET diaphragm is mainly the former film of two-layer mould release membrance bad person PET, namely behind the former film glue coating of PET, and the PET mould release membrance of fitting again.This product does not pass through specially treated, only possesses the basic functions such as anti-dirty.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of anti-side-looking PET diaphragm; can use ultra tiny shutter optical technology; effectively reduce the angles of display of display screen; the viewing area only has 60 degree; anyone looks in both sides can only see pitch-dark picture, makes screen content specialize in the user and reads in the front, can allow the user of computer and mobile phone not be subjected to the restriction of occasion; freely handle official business, effectively protect trade secret and individual privacy.
For solving the problems of the technologies described above; the technical scheme that the present invention adopts is: a kind of anti-side-looking PET diaphragm is provided; comprise the former film of PET mould release membrance, glue-line and PET; described a kind of anti-side-looking PET diaphragm also comprises polaroid; coated glue layer on the described PET mould release membrance; be covered with polaroid on the described glue-line, be covered with the former film of PET on the described polaroid.
The invention has the beneficial effects as follows: a kind of anti-side-looking PET diaphragm of the present invention; can use ultra tiny shutter optical technology; effectively reduce the angles of display of display screen; the viewing area only has 60 degree; anyone looks in both sides can only see pitch-dark picture, makes screen content specialize in the user and reads in the front, can allow the user of computer and mobile phone not be subjected to the restriction of occasion; freely handle official business, effectively protect trade secret and individual privacy.
