Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

The first embodiment.

Referring to fig. 1 and 2, the toughened glass film of the folding screen of the present invention comprises a transparent toughened glass layer 1 and a transparent AB glue layer 2, wherein the AB glue layer 2 is made of AB glue in the prior art, and the AB glue is a two-component epoxy resin adhesive, and has high transparency, and the cured adhesive is perfect, seamless, free of heating, curable at normal temperature, environment-friendly and nontoxic; high bonding strength, good toughness, oil resistance, water resistance and the like; the cured product has good electrical and physical properties such as insulation, compression resistance, low shrinkage rate and the like. The AB glue is prior art and is not described in detail herein. The toughened glass layer 1 and the AB glue layer 2 are adhered together, the thickness of the toughened glass layer 1 is 0.03-0.05mm, and the thickness of the AB glue layer 2 is 0.03-0.07 mm.

During the use, paste the toughened glass protection film and establish on mobile intelligent terminal's folding screen (like the OLED planar assembly of current folding screen cell-phone) via AB glue film 2, OLED's english is called organic light-Emitting Diode entirely, OLED belongs to the organic light Emitting device of a current type, OLED is prior art, and the toughened glass protection film protects the folding screen, avoids the folding screen to scrape the flower damage, prolongs the life of folding screen. The toughened glass protection film separately independent preparation with the smart mobile phone this moment, treat that the consumer purchases the smart mobile phone after, purchase again the utility model discloses a toughened glass protection film, then paste the toughened glass protection film and establish on the touch screen of smart mobile phone.

Certainly, can also with the utility model discloses a toughened glass protection film is integrative with the touch screen preparation, and after the touch screen preparation was accomplished, will the utility model discloses a toughened glass protection film directly laminates and forms touch screen unit on the touch screen, then assembles touch screen unit and cell-phone main part together, forms the smart mobile phone, and the smart mobile phone that the consumer purchased has the toughened glass protection film promptly. At the moment, the toughened glass protective film is used as an external screen main part of an OLED of a mobile phone screen of the original factory.

The strength of the toughened glass protective film is reduced through the thickness setting of the toughened glass layer 1 and the AB glue layer 2, and the toughened glass protective film is ensured to be freely bent along with the folding screen; in addition, utilize the thickness setting of toughened glass layer 1, AB glue film 2 to ensure the light transmissivity of toughened glass protection film, reduce the light blocking effect of toughened glass protection film to folding screen.

Folding screen is buckled when even taking AB glue film 2 and toughened glass layer 1 to buckle together, utilizes AB glue film 2 to support toughened glass layer 1, promotes the elasticity performance of toughened glass protection film, ensures that the toughened glass protection film can fully the reconversion after buckling, prolongs the life of toughened glass protection film.

In this embodiment, the structure of toughened glass layer 1 is the same with the structure of AB glue film 2, and toughened glass layer 1, AB glue film 2 all buckle along length direction's central line position. After the toughened glass protective film is pasted on the folding screen, the folding screen is designed for an external folding structure. Preferably, the toughened glass layer 1 and the AB glue layer 2 are both rectangular flat plates, and the toughened glass layer and the AB glue layer are overlapped and attached together.

In this embodiment, after folding the screen and buckling, AB glue film 2 buckles with toughened glass layer 1 along with folding the screen, and AB glue film 2 after buckling is located between the both ends about toughened glass layer 1 after buckling.

Example two

Referring to fig. 3 and 4, in the present embodiment, the number of the tempered glass layers 1 is two, the two tempered glass layers 1 have the same structure, the two tempered glass layers 1 are respectively attached to the left and right ends of the AB glue layer 2, and the buffer layer 3 attached to the middle of the AB glue layer 2 is disposed between the two tempered glass layers 1.

When folding screen buckled, folding screen drove AB glue film 2 and buckles, and two toughened glass layers 1 do not buckle, avoid toughened glass layer 1 because of bending the damage, the life of extension toughened glass protecting film. The buffer layer 3 compensates the change in the clearance between two toughened glass layers 1, avoids the clearance between two toughened glass layers 1 to change and leads to the toughened glass protective film to use badly, promotes the performance of toughened glass protective film.

Similarly, the toughened glass protective film can be used as an external screen main part of an OLED of a mobile phone screen of the original factory; the protective film can also be attached to the outer side of the folding screen of the smart phone independently to be used as the protective film.

In this embodiment, the buffer layer 3 is made of PET plastic, where PET is polyethylene terephthalate, and is prepared by exchanging dimethyl terephthalate with ethylene glycol or by esterifying terephthalic acid with ethylene glycol to synthesize dihydroxy ethyl terephthalate, and then performing polycondensation reaction, and the PET plastic is the prior art and is not described herein again. Utilize the characteristic of PET plastics, with PET plastics and two toughened glass layer 1 direct injection moulding together, increase the joint strength between PET plastics and the toughened glass layer 1, promote connection performance between them, promote assembly efficiency between them simultaneously.

Preferably, toughened glass layer 1 is close to the one end of buffer layer 3 and is equipped with the breach, and the breach is established from the terminal surface that toughened glass layer 1 is close to buffer layer 3 one end and is formed concavely, and the bore that the breach is close to buffer layer 3 one end is less than the bore that buffer layer 3 one end was kept away from to the breach, and buffer layer 3 is connected with and stretches into the intraoral dop of breach. The inner side wall of the gap is abutted against the blocking chuck to prevent the toughened glass layer 1 and the buffer layer 3 from being separated from each other.

In this embodiment, the buffer layer 3 is pasted and is established in AB glue film 2 along length direction's central line position department, and buffer layer 3 connects the one end that two toughened glass layers 1 are close to each other.

In this embodiment, after the toughened glass protective film subsides were established on folding screen, folding screen was folding structure of buckling in for, folding screen even takes the toughened glass protection film to buckle the back promptly, and two toughened glass layers 1 all are located between the both ends of the AB glue film 2 after buckling.

During the in-service use, AB glue film 2 is buckled with buffer layer 3 and is made two toughened glass layers 1 parallel arrangement, and the size in clearance changes when buffer layer 3 compensates the distance change between two toughened glass layers 1, ensures that two toughened glass layers 1 are firm all the time and pastes and establish on AB glue film 2.

In this embodiment, buffer layer 3 adopts transparent material to make, and two toughened glass layers 1 and the coplane setting of buffer layer 3 ensure the uniformity of buffer layer 3 and toughened glass layer 1 structure, avoid buffer layer 3 and toughened glass layer 1 inconsistent reduction consumer experience degree.

The rest of this embodiment is the same as the first embodiment, and the unexplained features in this embodiment are explained by the first embodiment, which is not described herein again.

The above description is only for the preferred embodiment of the present invention, and the present specification should not be construed as limiting the present invention.
