The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

The present embodiment provides an optical film structure, including:

the optical film comprises an optical film main body 10, wherein the optical film main body 10 comprises a first surface and a second surface, the first surface is provided with a first release film 20, and the second surface is provided with a second release film 30;

the adhesive film paper 40, the adhesive film paper 40 includes the bonding area 401 and the handle area 402, the adhesive film paper 40 is disposed at the corner position of the first release film 20, and the bonding area 401 is attached to the surface of the first release film 20.

The optical film body 10 is provided with a heavy release film and a light release film, the release film is a film having a surface energy distinction, and the release film has no stickiness or slight stickiness after contacting with a specific material under a limited condition. According to different release forces of the optical colloid, the optical colloid is divided into a heavy release film and a light release film.

Preferably, the first release film 20 is a heavy release film, and the second release film 30 is a light release film. The second release film 30 has a smaller release force than the first release film 20.

Preferably, a cover layer 101 is provided between the first release film 20 and the optical film main body.

Preferably, an adhesive layer 102 is disposed between the second release film 30 and the optical film main body.

Preferably, the size of the adhesive film paper 40 is smaller than that of the first release film 20.

The adhesive film paper 40 has the viscosity of common viscosity, high viscosity, strong viscosity and the like, and the release film is taken down by adopting the adhesive film paper 40, so that the convenience is realized, the time is saved, and no trace is left.

Preferably, the adhesive paper 40 has a rectangular shape. According to fig. 1-2, the adhesive film paper 40 is disposed at any one of the peripheral corners of the first release film 20, and the adhesive film paper 40 is disposed at the corner, so as to better avoid scratching the optical film main body 10 during the tearing process. The adhesive film paper 40 can be rectangular, or in other shapes, and only the adhesive film paper 40 needs to be torn away from the first release film 20, or can be set by a person skilled in the art according to requirements.

Preferably, the adhesive area 401 has adhesive and the handle area 402 has no adhesive. The adhesive film paper 40 is divided into two ends, one end is the bonding area 401, the other end is the handle area 402, the lower surface of the bonding area 401 has adhesive, the adhesive has strong adhesiveness, the single-sided attachment is facilitated on the heavy release film, the set handle area 402 is used for providing an upward pulling force, the heavy release film is torn off when the bonding area 401 is driven, time and labor are saved, no trace is left, the optical film main body 10 is not damaged, and the handle area 402 does not have adhesive preferably. The handle area 402 may also have an adhesive, and a protective paper is required to cover the adhesive portion of the handle area 402, so as to achieve the effect of no adhesive on the handle area 402.

Preferably, the handle area 402 enables the first release film 20 to be torn off. Because the adhesive force of the self-contained film of the optical film main body 10 is better, the film is difficult to be torn from the release film under the condition of no tearing, the production line can be torn from the original release film and then is replaced by the release film with weaker adhesive force, the manual tearing is convenient, according to the drawing 1-2, the adhesive film paper 40 is arranged on the heavy release film in the embodiment, one end of the adhesive film paper 40 is the handle area 402 without adhesive, the handle area 402 mainly provides an external pulling force point, when the pulling force acts, the other end adhesive area 401 of the adhesive film paper 40 can drive the heavy release film, and the effect of tearing from the heavy release film is achieved. In a preferred embodiment, the handle area 402 may be provided in different colors, such as red and blue, to better identify the pull area, with a manual tear-off operation.

Preferably, the optical film body 10, the first release film 20, and the second release film 30 are rectangular.

The setting of adhesive film paper 40 is in the heavy surface corner position of leaving the type membrane in this embodiment for directly tearing from heavy type membrane, according to actual demand, also can set up in the light surface corner position of leaving the type membrane, be used for directly tearing from light type membrane, can also two all set up adhesive film paper 40 from the type membrane surface.

The above detailed description of the optical film structure according to the embodiment of the present application is provided, and the principles and embodiments of the present application are described herein by using specific examples, and the above description of the embodiments is only provided to help understanding the method and the core concept of the present application; meanwhile, for a person skilled in the art, according to the idea of the present application, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present application.
