Abstract
The present disclosure provides a film cutting method, a film cutting device, a composite film, a backlight module and a display device. The film material cutting method includes: using a cutting tool provided with a viscous material to cut a composite film that includes at least two laminated optical films, with the viscous material on the cutting tool being transferred to a cutting end surface of the composite film during cutting; and, curing the viscous material on the cutting end surface.
Claims16
A film cutting method, comprising:
- using a cutting tool provided with a viscous material to cut a composite film that includes at least two laminated optical films, with the viscous material on the cutting tool being transferred to a cutting end surface of the composite film during cutting;
- and,
- curing the viscous material on the cutting end surface.
A film cutting device, comprising:
- a cutting mechanism including a cutting tool provided with viscous material;
- a feeding mechanism configured to convey a composite film that includes at least two laminated optical films to the cutting mechanism;
- and
- a cutting mechanism configured to, after the cutting tool cuts the composite film, cure the viscous material that is transferred from the cutting tool to a cutting end surface of the composite film.
A composite film comprising:
- at least two laminated optical films;
- a first viscous material disposed between the at least two laminated optical films and binding the at least two laminated optical films together;
- and
- a second viscous material disposed on a lateral end surface of the at least two laminated optical films.
