Mobile phone curved film, production method thereof, and curved attachment plate
View Patent ↗The present application discloses a curved attachment plate dedicated for mobile phone curved film, wherein the curved attachment plate comprises a planar region, a left bent region located at a left side of the planar region, and a right bent region located at a right side of the planar region, the left bent region is arranged corresponding to left sides of the curved toughened glass and curved explosion-proof film of the mobile phone curved film, and the right bent region is arranged corresponding to right sides of the curved toughened glass and curved explosion-proof film of the mobile phone curved film. The technical solution of the present application has the advantage of high user experience.
1. A method for producing a mobile phone curved film, which comprises:
a curved toughened glass and a curved explosion-proof film are bonded together and fixed, and an adhesive roller is employed to roll on a lower surface of the curved explosion-proof film to produce an adhesive layer, wherein a distance between a central axis of the adhesive roller and a planar region of a lower surface of the curved explosion-proof film is a constant C; a distance between a central axis of the adhesive roller and a home region of a lower surface of the curved explosion-proof film is L1, and L1=C+log 10 (w−m+1), wherein m is a distance from a point m of the home region in contact with an edge of the adhesive roller to a bottom line of the curved explosion-proof film, and w is a maximum value of the home region in X axis direction; a distance between a central axis of the adhesive roller and a special-shaped region of a lower surface of the curved explosion-proof film is L2, and L2=C+log 10 (s−n+1), wherein n is a distance from a point n of the special-shaped region in contact with an edge of the adhesive roller to a top line of the curved explosion-proof film, and s is a maximum value of the special-shaped region in X axis direction,
the curved attachment plate is bonded with the lower surface of the curved explosion-proof film through the adhesive layer.
2. The method of claim 1 , wherein the curved attachment plate comprises:
a planar region, a left bent region located at a left side of the planar region, and a right bent region located at a right side of the planar region, wherein the left bent region is arranged corresponding to left sides of the curved toughened glass and curved explosion-proof film, and the right bent region is arranged corresponding to right sides of the curved toughened glass and curved explosion-proof film.
3. The method of claim 1 , wherein an arched region is arranged at an upper side of the curved attachment plate, and the arched region is arranged corresponding to special-shaped regions of the curved toughened glass and curved explosion-proof film.
4. The method of claim 1 , wherein the adhesive layer is made of AB adhesive.
