Screen protection paste

Abstract

The invention provides a screen protection paste. The screen protection paste comprises a protection paste (1), a back-adhesive layer (2) and a backing paper (3), wherein a screen protection area (11) and a panel protection area (12) are formed on the back of the protection paste (1); the front surface of the back-adhesive layer (2) is clung to the back of the protection paste (1); the front surface of the backing paper (3) is connected to the back of the protection paste (1) by the back-adhesive layer (2); an expanding surface of the back-adhesive layer (2) is only limited to the panel protection area (12); a plurality of lug bosses (10) extend from the protection paste (1) to the back direction; and a clearance (9) is formed between the screen protection area (11) and the backing paper (3). According to the screen protecting paste, the static electricity can be removed by the lug bosses, thus the paste is easier to be coated; and the lug bosses are manufactured by means of die casting, the process is simple and stable, and the yield is high.

Description

technical field [0001] The invention relates to a protective film for protecting a screen, in particular to a protective film suitable for a touch screen of a hand-held electronic device, in particular to a screen protective film. Background technique [0002] The touch screen of a handheld electronic device is protected by a film, which can protect it from scratches, oil stains, etc. Common pasting films in the prior art have the following two types: [0003] One is that the entire area of ​​the film adopts a composite layer structure. For example, the utility model patent whose notification number is CN202261425U and whose name is "a mobile phone film" discloses a three-layer composite structure. Its disadvantage is that unskilled users are still prone to air bubbles when sticking the film. [0004] The other is that the local area of ​​the film adopts a composite layer structure. For example, the invention application with the publication number CN102508522A and title...

AI Technical Summary

Problems solved by technology

Its disadvantage is that unskilled users are still prone to air bubbles when sticking the film

Its disadvantages are: the patent adopts the arrangement of particles on the back side of the plastic film to provide antistatic effect, but the production process of this method is relatively complicated. In addition, the technical solution of the invention application uses the printing particle method, which is easy to cause defective products and unsatisfactory products. Durable (such as not wear-resistant), and the spacing between the particles cannot be exactly the same, so the particle distribution is uneven, which affects the antistatic effect and avoids optical effects such as light separation and clarity
